Why LED lighting better competent for our lives

We implemented a large-scale urban renovation project last year, we mainly improved the city's lighting, because our city is the same as other cities where the streets are lighted up every night, especially in the square, waiting rooms, parks, tunnels, etc. The public environment must be lit all the night, so the annual electricity financial investment is quite large, which almost account for the third of the whole financial investment in urban construction, government decided to vigorously transform lighting facilities to change the current, I naturally involved in the beginning as urban design division, we have compared the many other lighting facilities, the LED light :100 lumens per watt, 50,000 hours, fluorescent: 80W 100 lumens / watt, 24,000 hours; HPS: 91 lm / W, 16,000 hours; metal halide lamps: 65 lm / W, 12,000 hours; Incandescent: 13 lm / W, 1200 hours, we can clearly see luminous efficiency of the LED light is the highest and the use of time is longest, so we surely put LED as the best choice for lighting objects.

Make sure the LED lighting is the best lighting, we began to search which is the best suppliers, as a large renovation project, because a huge amount of lighting is required, we can not shop in Amazon that is shopping site for small customers to find, we need to cooperate with LED manufacturers , we have referred to proposals of other departments of urban design and found on

B2B platform, e we finally locked in China wher

e the manufacture is developed, but we were unwilling to cooperate with  well-known  LED manufacturers, because the prices of high-profile product with the same quality are generally much higher than other manufacturers, so what our best choice is that small lighting enterprise specialize in relatively low price and high quality products, through further screening, we found this a manufacturer that has very good reputation named Lead lighting, we originally purchased the LED tunnel light, because most of tunnel lights often need to be maintained and replaced, we firstly viewed their tunnel lights product page www.lead-lighting.com/products/bid32-1.htm, user-friendly design and detailed explanation did not only allow us to easily find what we need, but we could learn more about the performance of LED tunnel light, we thought the product of such company designing so professional web site must not be inferior, and soon their salesman replied me as soon as we send the inquiry, we are very satisfied with their simple and humor simple response, our procurement staff decided to visit the lighting company, according to them, so they are very astonished by their neat and bright plant and warm and harmony production research and development team,，we surely didn’t purchased 200PCS tunnel lights until compared to the price, tunnel lights were sent to our hands after less than a week delivery, plus with detailed installation instructions, they didn’t forgot to call on our technical staff to explain precautions, and then we also ordered LED floodlights and other LED lighting products, from January last year to now, in addition to LED tunnel lights lit for 24 hours need to be simply repaired and maintained, floodlights are basically not out of any problem, and fifth of electricity financial investment in the prior year was saved compared to the previous year, visible, LED lighting is obvious known as energy saving.

Of course, I believe there are many of my friends having benefited from LED lighting, although the price is relatively higher than normal lighting products, but the latter more than offset by savings in electricity purchase more investment, this is my personal experience as an urban planner, I hope one day LED lighting can enter every household in our city, thanks to LED lighting, our health has more sub-guarantee, our lives has more laughter，our environment has less pollution.

The personally experience tells Why LED Lighting

I am a city designer and responsible for the planning and design urban lighting, especially when darkness has fallen，the bright lights flash in the streets, the pastel and bright  city square , parks, stadium and waiting room where we amuse and leisure and watch the game and quietly wait room the LED flood light illuminate, we are safely driving in the tunnel illuminated by LED tunnel lights, I am always having a noble feeling that their convenience and enjoyment and fun is brought by LED lighting I personally designed，which also bring my own convenience as the city’s citizen, but, it is really a way to kill two birds with one stone, meanwhile，I must thank a good lighting supplier Lead lightinghttp://www.lead-lighting.com due to professional LED lighting they provided, I participate in the planning and construction the city with the help of LED lighting, I am always feeling very honored.

Each of us must spends each night along with lights, so lighting in our lives has played a pivotal role, and now we increasingly accelerated pace of life, the heavy burden has been also increasing our mental stress, the LED lighting emits soft lighting that not only does not irritate the eyes, but also can relieve our stress and improve working and learning efficiency, the environment is now more and more abnormal, because more and more serious pollution is caused by lighting, the LED lighting as an energy-saving semiconductor product can be effectively solved the problem. It significance improve energy efficiency and reduce waste into heat so that not only effectively describes our expenditure on electricity, more importantly, but also reduce greenhouse gases and dust pollution of the atmosphere caused by coal power generation.

Do you know LED stadium light

China Network Association (Jiangmen) tennis training base installed the high-power integrated module package LED stadium lights, which initiated the use of LED stadium lights nationwide and have been paid attention to by the Guangdong provincial tennis.

LED stadium lamp adopts LED floodlights design and lighting principles, using  high-power integrated package module further improves and enhances the strength and breadth of lighting，it has the same advantage as LED flood light that is known as energy saving, environmental protection, low-carbon, emissions, etc., compared to traditional sodium lamp， energy saving is up to 60%, its service life is 10 times longer and has high reliability and stability. The practical test shows that its service life is 50,000 hours or more, which efficiently solve instability, frequent failures, serious loss, large lumen, modeling monotonous and higher maintenance costs many drawback the stadium lights luminous efficiency has always existed.

With the development of rapid economy society，the construction of community sports venue that is to improve the physical fitness of the general public as the carrier has been changed with each new day , but what the hot topic of NPC deputies and CPPCC members motions and proposals is that the utilization rate of the venue is not high. Number of community sports will be "black light" district in the evening ，the youth including the schoolchildren are attracted by colorful mahjong parlors and Internet cafes, causing social instability. The crux of the problem lies in significant energy consumption of the existing stadium light, which is easy to wear and tear, therefore, the task of charged with green lighting LED stadium lights came into being.

Currently, the international common consider that photonics technology is cutting-edge technology of the 21st century. If sort the most significant representatives of leading industries in the 21st century,: first is photonics industry; second is the information communication industry; Third, health and welfare industries. The LED optoelectronics industry is the most important optoelectronic materials and components, based on the entire photonics industry. The successful development of stadium lights will become an exotic flower of sports industry. In accordance with the formulation of the sports industry category focused on sports consumption, fitness services, sports equipment, etc in the past., today stadium green light will be the new way to grow a valid extension. It has more development potential  than any other individual industry.

Some tips to help you choose the most suitable LED light

LED lighting as energy saving products has been more and more accepted by consumers, but most consumers are lack of understanding the LED, but also do not understand the complex jargon, little knowledge about how to purchase LED lamps is compiled to share with readers.

First, we need to know what the core values ​​of LED lamps is? Do you have these needs? The main advantages of LED lamps is energy-saving, long life, rich light color and stylish.

Second, cost. From a cost perspective, the price of LED lighting is about 3-10 times higher than the traditional lamp，the electricity is used for six hours or more every day, it is cost-effective to use LED lighting，which is expected to be able to save money that is equal to the money used for buying light about a year; if using 2-3 hours each day, there is not much electricity bills saved.

Third, the value .Of course, not all of the activities is only pursuit for the money in the whole human life, but fashion and accept new things that is an attitude towards life.

Fourth, the quality. determining to buy LED lamps, you will look for yourself what kind of quality of LED lamps. Currently the state has not yet introduced quality standards of LED lighting, so the quality of LED products on the market is uneven, and some no-name goods are always used very cheap poor quality chips, said 1W, actually only 0.5W-0.7W, and manufacturers increase the output current of drive power to produce high brightness, which will cause serious bad light. Should choose some have their own brand of products, Lead lighting with absolute sincerity attitude to service every new and old customers and adhere to choose qualified LED chips and chip and has never produced any shoddy LED lighting, , and now LED floodlights, LED tunnel light, LED tube and other indoor and outdoor lighting have been exported to Europe, America and other countries where the LED lighting is also popular, you can loge in  LED Tunnel Light page www.lead-lighting.com/products/bid32-1.htm to view more vivid and specific LED tunnel lights or go homepage to looking for your LED lighting

 Fifth, after-sales service. We’d better ask for the agents to know how long warranty period of the product is, the insurance of some bad products is only one year, which is almost the same life as the traditional energy-saving lamp, but the price is yet expensive, it is not worth.

Sixth, the other is how to choose product features, such as LED ceiling light (also called LED lighting) and LED grille lights are converging products, they are mainly for highlighting local lighting, according to the requirements of luminous efficiency they can be customized 5 degrees , 15 degrees, 30 degrees, 60 degrees, different angles lens; LED downlights are the products of LED flood light, its main function is lighting; LED strip lights are mainly used for auxiliary light efficiency, T5 lamp is relatively common, what its advantages is in addition to save power，it can also be used in curved spaces, such as the ceiling.

What’s the main character of LED light compare to incandescent and energy-saving lamps

The illumination of LED lamp is not only much better than incandescent, but also much higher than the energy-saving lamps, the illuminance uniformity of the incandescent is most evenly, but if you do not use the condenser component， part of the light can be wasted, so energy-saving lamps and LED lights still perform better on practical aspect.

English: This is a stage lighting test comparison between the American DJ LED 64 Pro, one of the brightest RGB LED fixtures currently available, and a traditional PAR-54 300 watt medium flood incandescent made by General Electric. This image shows the lighting on a cart in a computer lab classroom. (Photo credit: Wikipedia)

The incandescent can excellently control color temperature, but which does not mean that other lighting poorly control color temperature. In the tested products, the color temperature controls of most products are in line with our lighting needs, the user should select the color temperature that is less than 200K controlled by the lighting, and the color temperature of the lamps is from 45 degrees to 135 degrees.

The results speak for themselves in energy efficiency. LED with high electro-optic conversion rate has been the lowest energy consumption, electricity generated is the least, but if you want to get more obvious electricity savings, we need to use a plurality of LED lamps to achieve energy saving.

The energy-saving lamps have higher temperatures, but also spent more energy in heat, LED lamp temperature is better controlled, if you want better cooling effect, I recommend that you choose to use the cooling fins of the LED lights.

In the strobe lights, the incandescent lamp don’t better perform as we might expect, energy-saving lamps also flicker, LED lights behave differently, some products perform better.

In general, no matter contrast with energy-saving lamps and incandescent, LED lights has obvious advantages in many ways, but also is the future development of the lighting direction, but different quality of LED lights actually unevenly perform, which also requires the user according to their actual needs to choose products.

Lead lighting with professional R & D and production teams adopts high quality LED materials to focus on producing more environmentally friendly and energy-saving LED floodlights, LED tunnel light, LED tube and other indoor and outdoor LED lighting products, high power LED floodlights and LED tunnel lights have been exported to Europe and critically acclaimed, if you want to know more LED tunnel lights, you can browse  www.lead-lighting.com/products/bid32-1.htmor or return home for more LED lighting

The second key of design tunnel lighting—controlling the glare and stroboscopic

Why the glare form in the tunnel is because that there is the very high brightness or luminance contrast, making the eye function decline or discomfort. The glare of the tunnel lighting comes from oncoming vehicles headlights, tunnel lamps, high brightness outside the tunnel exit. Glare will make people fall on the ability to identify obstacles and endanger traffic safety. Tunnel lighting should be cut light type, taking direct and reflected glare elimination special technical measures, the formation of diffuse reflection, so that light entering the eye is very soft.

International Commission on Illumination uses a relative threshold increment (TI) to illustrate the glare causes decline in visual function, ie, a measure of disability glare. European Standards Committee tunnel lighting standards (CR 14380:2003 E), on disability glare provides as follows: during the day inside the tunnel threshold segment and the entire tunnel section and the night, and its relative threshold increment (TI) must be less than 15% .

stroboscopic effect
Strobe means that since the illuminator is not arranged in a row, the driver constantly exposed to the stimulus generating shading upset in a long tunnel,. It is related to the changing brightness , the changing frequency , the total time of strobe，which is linked with optical characteristics of the lamps , the traveling speed of the vehicle, the lighting installation spacing, the tunnel length. In general,what the flicker is acceptable is that strobe frequency is less than 2.5 and greater than 15Hz .

If the vehicle speed is 60km / h is 16.6m / s, lighting installation pitch is 4, so that the frequency of strobe is about 4.2Hz. When designing, choosing the appropriate lighting installation spacing should be taken into account, . If the strobe frequency lies between 4Hz and 11Hz, and lasts is longer than 20s,which will bring that the driver feel obviously uncomfortable.

Browse www.lead-lighting.com/led-tunnel-light/led-tunnel-light-cl3-60w.htm， you can know more LED tunnel light and learn about its parameters and scope and why it is suitable for tunnel lighting.

The first key of designing tunnel lighting—brightness

Highway tunnel lighting has its own characteristics, which is different from ordinary road lighting. the design of the following points should needed to be considered and paid attention to:

1.the road should have a certain level of brightness

2 the tunnel wall should have a certain level of brightness

3 design speed, traffic volume, route alignment, and many other factors

4 Considering the driving safety and comfort and other aspects to determine the level of illumination

5 human visual adaptability, especially the tunnel entrance and outlet sections, etc.

6 the tunnel needs lighting daytime, but the problems of lighting during the day is more complicated than at night.

How to achieve energy savings and improve lighting effects and ensure traffic safety and comfort in the tunnel lighting is usually available from the following aspects to be considered:

(1) Brightness

As the brightness of the day is much higher than outside, therefore when the driver drove into the tunnel, there is a certain visual adaptation time before you can see the situation inside the tunnel, a phenomenon called "adaptive hysteresis," if there is no proper transition, it will produce a black hole phenomenon, so that the driver temporarily lost normal visual function, which will bring to certain security risks. Black hole phenomenon is not only occurring before entering the tunnel vision problems, but also the tunnel lighting is the most important issue. The tunnel lighting is usually divided into the entrance tunnel lighting, interior lighting and exit lighting. Wherein the brightness of tunnel entrance lighting at daytime is determined by the brightness outside the tunnel, the speed, the view of the entrance field and the length of the tunnel. Threshold section is to eliminate the "black hole" phenomenon, the illumination levels of the transition section further gradually decreased so as to provide the driver with visual dark adaptation time.

(2) brightness uniformity

Good visual function not only requires a good average brightness, but average luminance on the road is not much different with the minimum brightness. If the brightness of the view field is too large different, bright parts will form a glare source, and the light and dark will bring some changes in stroboscopic effect, thereby affecting vision, human visual effect will be significantly worse, while the visual fatigue will increase.

Overall brightness uniformity U0 is the minimum brightness and the average ratio of brightness on the road inside the tunnel section, vertical uniformity axis U1 is the smallest brightness and maximum surface brightness ratio in the driveway surface. If the road surface continuously, repeatedly emerges bright bands and dark bands, namely "zebra effect", the users travelling in this lane road will feel very irritable. This issue relates to human psychology, but it can also endanger road safety, the longitudinal uniformity is mainly used to evaluate the "zebra" effect size.

What should be taken into account when designing the LED tunnel light

Tunnel lighting design should not only take into account the length, linear, interior, road types, with or without sidewalks, structure linking the roads, the design speed, traffic volume and car types, etc., but also considering the light source color, lighting, arrangement, lighting level, brightness outside the tunnel and eye adaptation status, tunnel lighting is designed to solve the issue of this series.

Energy-saving of tunnel light offers requests for the lighting, lamps, lighting methods, energy saving includes management and designing lighting, designing lighting is the most important measures for energy saving, which include the using innovative and reliable design and reasonable standard value, and adopting efficient lighting, efficient lighting, increasing the light reflectance and lighting control and energy saving. Compared with the traditional light, what’s the biggest advantage of LED tunnel light is energy and stability, so based on the advantages and features of LED，the efficiency of the LED chip should be improved, reasonable light fixture must be designed to enhance the overall performance, LED tunnel lighting is needed to address the important issues.

The source and light efficiency of the LED tunnel light is a basic indicator that measure whether the efficiency of the tunnel light is excellent or not, according to the requirements in practice, LED tunnel lights need to reach a certain level of light efficiency to meet the replacement of traditional road lighting sodium, metal halide needs.

Take a good look at www.lead-lighting.com/products/bid32-1.htm you will to learn about more and better LED Tunnel Light.

What's the main advantages of LED tunnel light

Led tunnel lamp is known as energy saving and emits efficiency light, it adopts light-emitting diode (LED) as a light source so that it has high luminous efficiency, long life matching with different reflector can be achieved multipurpose lighting; after softening, do not make produce glare or other discomfort. It selects overheating protection technology as ballast to ensure lamp life. The reflector is made of imported high purity anodized aluminum mirror and designed ​​by precision optical, power factor is greater than 0.9,    the LED Tunnel Light has advantages of reflective, high efficiency, good transparency, energy saving and environmental protection.

LED tunnel light is a solid-state semiconductor device contrast with conventional LED, which can directly convert electricity into light, compared to traditional road tunnel lighting (sodium, metal halide, etc.), LED light source has the following advantages:

(1) light decay: If conditions are favorable in the case of cooling, the light fade of LED is Masamitsu failure during 10000h,the light fades is 3% a 10% before 10000h, 30% during 50000h , which far below the normal road lighting, it emits more stably.

(2) high color: Normal LED color is about 70 ~ 80, if trichromatic phosphor is higher; HPS generally is 20 to 35, low pressure sodium is lower, so even the brightness of the traditional light is higher than the LED, but the visual effect is worse than the LED, "not the brightest, but can see most clearly," this should be the application developing direction of the LED light source.

(3) life: the life of LED is currently higher than general road tunnel lighting that is more higher than 50000H.

(4) Price: Although the current prices is higher than traditional lighting, but with the manufacturing technology matures, its price is currently constantly significantly dropped, the price of the high and low pressure sodium lamps generally set 2,000 yuan, while its cable and other accessories member price is higher than the LED cable and other expenses.

In addition, LED tunnel light also has advantages of high coefficient of maintenance, security, performance, no flicker and energy saving and environmental protection .

What is the preferable lighting for courtyard

I am an environmental enthusiasts, I often study energy-saving products, LED lighting as the fourth generation of lighting products is known for their eco-friendliness, LED floodlights and LED tunnel lights are mainly used for outdoor lighting, LED floodlights are used in stadiums, squares, large commercial buildings, fountains, parks and other commercial lighting and public lighting, LED tunnel lights is used for traffic lighting, they are high-power LED light, and LED tubes, LED bulbs, LED ceiling lamp, LED panels are mainly used for interior lighting,the courtyard as the outdoor environment because the place is relatively wide, mostly using LED floodlights.

Why LED flood lights have better effect on energy-saving relative to traditional light is because that the LED floodlight adopts semiconductor light-emitting principle, reducing large amounts of luminous infrared and ultraviolet light generated by the inert gases containing in the energy-saving lamps and fluorescent lamps and light pollution, and the LED flood light has no mercury, lead and other heavy metals that hazards human and environment, the pink Lane of the energy-saving lamps and fluorescent light is added a small amount of heavy metals, so LED floodlight doesn't cause secondary pollution to the environment, so it is known as environmental protection, low-voltage constant current driver converts alternating current into direct current so that the light emitted is more stable, reducing the flicker of light and not to hurt the eyes, but also improve the effective utilization of current, saving the waste of current into heat, so energy saving.

Of course, what I installed in my courtyard is also LED floodlights, at the beginning ，I also worried about which LED light is best for my yard, I naturally considered finding affordable products, I have some of the engineering and designing friends, they are often associated with lighting designed to deal with, my engineer friend Dick is primarily responsible for construction site lighting, their projects that is developed and designed  such as stadiums, subways are also using LED floodlights and LED tunnel lights, they are often cooperate with a Chinese LED manufacturing companies, he is always talking about topic of LED lighting applied as the energy saving lighting in the 21 century, so I surely want to seek his advice when deciding to use LED lighting, and he recommended me to buy from a Chinese LED lighting manufacturers,I didn't made up my mind until I viewed their Home www.lead-lighting.com/products/bid19-1.htm , because I rarely see business website that specialize in thoughtful design and detailing, I asked the price, they answered in detail and warm service made me decision in this attitude of professional companies to buy good products, I and my friend together ordered 10 LED floodlight, although such a small order for such high-volume businesses would not be considered, but they still individually produced for us, plus，when arrived less than a week delivery schedule, they specially talked on the phone to tell us special attention, the LED floodlights have been used for almost a year until now, there has been nothing problem with starting，replacement, glare, and it has saved us an average of nearly one hundred electricity bills each month.

What‘s the advantage of LED light compare with energy-saving lamps

The LED light has no heavy metal pollution and is more healthy

In recent years, the state has been promotion energy-saving lamps as a lighting tool in order to save more resources,. Energy-saving lamps reduce the waste of electricity in some extent, but bringing many risks can not be underestimated.

CFL glass tubes contain inert gases, trace heavy metals such as mercury and lead which is activated to emission by electrical. Mercury and lead, heavy metals are toxic substances, once saving lamps is accidentally broke, they may cause injury to persons. Reporters learned that a common energy-saving lamps contain tens of micrograms mercury, and one milligram mercury can cause fish death in the pond.

As we all know, why LED light emits light is because light emitting diode， LED bulb does not contain anything heavy metals and consist of a variety of electronic components, so do not harm to the human body.

LED bulbs still need to take special recycling as general light bulbs, electronic products. Recycling electronic products should be gradually taken seriously, LED bulbs considerably reduces the harm to our body, but the we should still be correctly discard them.

Although energy-saving lamps still dominate the market, it is no doubt that LED light as semiconductor tech lighting is much advancer than energy saving lamp, and the unique design ensure that it is more environmentally friendly, the LED lighting technology becomes more mature especially in the public lighting such as LED flood light, LED tunnel lights and other outdoor venues and residential lighting such as LED tube, etc. have been applied more widely, but also a large number of companies specializing in LED lighting appeared, Lead lighting is famous for its leading peer technology and professional R & D and manufacturing teams that have  produced environmentally friendly and energy saving LED lighting to suitable for mass consumption, Lead lighting whose homepage is www.lead-lighting.com work with us to practice low-carbon green living

What‘s the advantage of LED light compare with incandescent lamp

After testing more than 1600 kinds of materials, Edison eventually placed  tungsten having longish life inside incandescent, so the world bright. In the past, incandescent have been accompanying us for more than 100 years, but it was found that it is bad in energy-saving and easily damaged after prolonged use. "Filament will be black, and then not so bright and tungsten are also particularly vulnerable to being blown." ，which is our common experience, we have to frequently replace bulbs. Looking around the world, 1/5 of the electricity is used for lighting, we can see how much power consumption is.

A few years ago, European countries began to prohibit the use of incandescent lamps, and China also issued a notice that it would phase out incandescent a few years ago , and planed a detailed route for incandescent exiting: from November 1, 2011 to September 30，2012 is the transition period, October 1, the importing and selling100 watts and above ordinary incandescent lighting was banned in 2012, the importing and selling 60 watts and above ordinary incandescent lighting will be banned on October 1, 2014,from May 10，2015 to September 30, 2016 is the mid-term evaluation period， the importing and selling 15 watts and above ordinary incandescent lighting will be banned on October 1, 2016, or, as the mid-term evaluation results to adjust. Implemented until now, it has been difficult to find a 100-watt incandescent lamp and above it for general lighting in the market.

Compared with incandescent consuming Large power, LED bulbs relying on light-emitting diode it very good at energy-saving, life expectancy is ten times longer than incandescent. Meanwhile, our hands will feel the heat of the lamp when closing to the incandescent lamp, the LED lamp itself does not generate heat but a dedicated heat sink outside, it will not burn hands.

Some cosmetics stated on the promotional materials, the beauty of women should pay attention to indoor sun. Some people may wonder why we need sunscreen in room where there is no sun, it is also because that the traditional incandescent light contains part of ultraviolet and infrared that has sunburn risk to us we using LED lighting aren't worry about any more.

Nowadays, LED lighting has gradually taken up space on the market, although not the large-scale application in home lighting, fluorescent still dominant, but as our awareness of environmental protection and LED lighting technology innovation, more and more LED lighting that is close to our live has gradually appeared, and more and more LED commercial lighting whose technology is currently obvious mature such as LED flood light and LED tunnel lights etc. have occupied large market, many lighting manufacturers due to the professional LED technology and attentive service is enthusiastically welcomed by the people, Lead lighting www.lead-lighting.com is one of them, we believe we together with these LED lighting manufacturers spear LED to every corner of the world so that the Earth will been revitalized.

What is development direction of LED lighting in 2013

2013, home lighting market will no longer be confined to the lighting ingredients and gradually develop toward the effect, styling, technology and application of new technologies, materials changes and other direction.Therefore, consumer demand presents nine trends in the lighting market:     

First, respect for nature. cater to innocence and respect for nature, using a variety of wood sculpture, no less real than handicraft.     

Second, the functional subdivision. People are no longer merely satisfied lighting function，requirements for a variety of lamps came into being.     

Third, luxury shape. decorative lighting is increasingly luxury, high-grade in High-grade office buildings, luxury hotels, restaurants and other public facilities. such as LED flood light. 

Fourth, multifunctional. Such as live table lamp, desk lamp with music box, there is a bedside lamp doubles as photosensitive phone controlled lights, night indirect call, the lamp will automatically light up, can automatically turn off after hanging up about 50 seconds delay.     

Five high technology. No strobe light, three wavelengths chromatography adjustable lights, red lights, and other radiation far-infrared have the function to protect eyesight lamps onto the market.     

Six, energy conservation. Energy-saving lamps is popular with consumers.     

Seven, environmental protection. Environmental protection is a brand new topics of lamp production technology, shows that people pay great attention to living environment in the living room and concerned that this is the main development direction of home lighting in future.     

Eight, rich colors. Today lighting market is synchronizing with colorful life, wearing "colorful" coat, a red maple leaf, natural blue, coral, yellow, and green plants, color, look elegant and warm.     

Nine, used in combination. It is also a popular fashion that nine residential Lighting changing trend combines with lighting and the daily routine, such as a ceiling fan lights, round mirror lights, flashlights yellow lights.

How to choose the preferable LED lighting

We can choose the preferable LED light according to above tips

1, brightness  Different brightness have different prices. The LED source shall comply with Laser ClassⅠ standards.

2, antistatic ability  The LED lighting that has strong antistatic ability have longer life, and therefore higher prices. Usually static than 700V can be used for LED lighting.

3, the same wavelength  The LED having the same wavelength emits the same color, such as requiring the same color, then，it is difficult to produce pure colors for the manufacturers not having LED spectral separation device.

4, the leakage current  LED is one-way conductive light, reverse current is called leakage, the larger the leakage current is LED, the shorter and lower the life and prices is.

5 LED light-emitting angle  Different usage hasn't the same light-emitting angle . Special light-emitting angle have higher prices. If all diffusion angle, higher prices.

6, the different life  Quality is the key to life, life is determined by the light fades. The Smaller the Light decay is, the longer and higher the life and price. Is.

7, the light chip  The different chips have vary widely prices. Japan, the U.S. chip is expensive, and chip generally made in Taiwan is lower than Japan and the U.S..

8, the chip size  The big is better than small. Price proportional to the size

9, colloidal  Ordinary LED colloidal generally epoxy resin, plus a UV LED and fire agents is more expensive, high-quality outdoor LED lighting should resist UV and fire.

Each product surely have different design, different designs apply for different purposes, reliability design of LED lighting include: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, safe use of time and other factors. As far as electrical safety concerned， should be consistent with relevant international, country standards. As the LED is a new product, the standards lag behind , but each country provides product qualification testing. The price of LED lighting with international safety certification (such as GS, CE, UL, etc.) and country product quality certification is dear, because these products are designed to be safe and reliable. What Consumers must pay attention to is that the authenticity of the certificate should be carefully identified, there aren't currently many manufacturers passed international safety certification and country product certification. But lead lighting whose home page is www.lead-lighting.com just one of them that specializes in LED flood light，LED tunnel light and LED tube and other indoor and outdoor lighting.

Why is LED tunnel light most suitable for tunnel lighting

At present, the high pressure sodium lamp obtain a large-scale applications because of higher photopic luminous efficiency (up to 120lm / w) in lighting source adopting tunnel lighting, but it is still more difficult to overcome the main problem that is poor color and scope and limited choice of power source (usually only choose 250W and 400W) high pressure sodium lighting in the tunnel, especially in the interior section lighting, high pressure sodium has no less power, on the other hand, glare and flicker caused by strong punctate light is more serious.

 

In some long tunnel, the straight tube fluorescent lamps because of its high color rendering and a good visual inducing linear light has also been a number of applications, but the life of the fluorescent lamp is short, usually only about 8,000 hours, and it often needs to be replaced, greatly increasing the maintenance cost of the tunnel. In addition, fluorescent less power can not meet the requirements at the entrance stage, transitional stage and outlet areas that require high illuminance. In recent years as the electrodeless lamp matures, due to the elimination the electrode factors, compared to traditional fluorescent lamp electrodeless fluorescent lamps have a longer life and more power, which makes the lamp reflected an advantage in the tunnel lighting applications. But lamp emitting surface is larger, when making optical designing，the optical efficiency is low. The LED tunnel light can be said is the integration of high-pressure sodium lamps, straight tube fluorescent lamp and various advantages.

How to overhaul that the component of led lamps is significantly damaged

1, although fuse is not burned, neither do the line ，resistance is apparently damaged， beyond doubt.，transistor must be damaged ，which is may be caused by the aging of the lamp, followed by poor using environment, the other may be caused by C1 losing capacity. For the first two cases, replace resistors, transistors, the best is replacing matching C3, C4 small electrolysis. For the latter, C3, C4 does not have to be replaced, because C1 operates under high pressure, be sure to use high-quality heat-resistant electrolytic capacitors substitution.

2,fuse burned, in the case of the line burned, if C1, Q1, Q2 intact, you must individually routine inspection and pressure testing for D1 ~ D4. Or the D1 ~ D4 all with quality product substitution.

3, C1 burst, if accompanied fusing insurance, blown the line ， D1 ~ D4, C1 to all should be replaced.

4, only one side of the RC element Q2, transistor is burned, C2， should focus on checking whether the breakdown.

5, if high-frequency transformer B is damaged, the∮ 0.32mm  high strength line can wound on  a 10mm × 6mm × 5mm high-frequency magnetic, T1, T2 should be wounded the four laps; T3 8 ring (note head and tail). Chokes L: lamp power is  5 ~ 40W, corresponding to between 1.5 ~ 5.5mH

Definitely, choosing a good quality LED lighting is also a key factor eliminating failure, Lead lighting LED lighting stick to adopt qualified materials to produce a variety of energy saving LED flood light, LED tunnel lights, LED tube and other indoor and outdoor lighting, we believe that Lead lighting www.lead-lighting.com must surely lead us closer to energy-saving life with excellent quality and the constant pursuit of innovation for our level of consumption.

How to overhaul that led light does not illuminate

1, common is the resonant capacitor C6 breakdown (short circuit) or pressure reduction (soft breakdown), should be replaced by the high-quality polyester or CBB capacitor that the same voltage capacity is above 1kV .

2, open filament lamp. If the lamp is not serious black, parallel 0.047μF/400V  across broken wire foot after emergency use polyester capacitors.

3, R1, R2 open or variable value (generally greater possibility is failure in R1),substitution with the same high-resistance resistor 1/4W .

4, transistor open. Found that only one transistor open, but can not replace one,  should replace one pair of voltage above 400V same model in pairing switch. Or prone to rolling or re-burn tube lights.

5, lights flashing. If lamp is serious black, check D5, D6 whether the Weld or open, if D5, D6 soft breakdown or filter capacitor C1 leakage and adverse, which also make lights flash.

6,it is difficult to light up  the lamp , sometimes touching the lamp can be lit or lights roll, which may be C3, C4 insufficient capacity mismatch.

7, if the single low-power energy-saving lamps lit filament emerging redness or luminous phenomena should also check whether the soft breakdown D1 ~ D4, C1 is installed backwards or leakage, power supply part  is short circuit or not.

8, Chokes L, and the oscillation transformer B, cores are broken. Should single core change, we should pay attention to three points: (1) using the core to meet the requirements, otherwise it may cause choke inductance values ​​have greater access to lay hidden energy-saving lamps; (2) the magnetic gap is not too small, so magnetic saturation; (3) after interstitial magnetic material with a suitable pad，a good pad with adhesive glue and wrap high temperature flame retardant tape, to prevent loosening. In addition can not pick the wrong side to B with the same name.

9, repair using trigger tube electronic ballast, should focus on checking bidirectional trigger diode, this pipe is generally used DB3 type, it's two-way breakdown voltage is 32 ± 4V.

Lead lighting basically adopts high quality LED lighting chip and power so that the power LED Outdoor Lighting such as LED flood light, LED tunnel lamp does not damage after the long-term use, reducing repair and maintenance and the human and material resources commitment and traffic accidents, which is the preferable choice for variety of outdoor lighting, while LED tube greatly restore the most realistic lighting effects and save a lot of electricity costs due to high-quality energy-saving and soft lighting for commercial lighting and home lighting, we can find more high-quality LED lighting in www.lead-lighting.com, Li Sida lighting join us to usher in more comfortable and natural tomorrow.

LED lighting has four percent growth in China

According to McKinsey & Company reported that in 2012, China accounted for 45% of the lighting market in Asia, while the LED lighting account for 12% in the Chinese lighting market. According to McKinsey & Company predicted that from now until 2016, the compound annual growth rate will reach 43% in Chinese LED general lighting market.

China LED lighting market

The Dow Corning analysis, more advanced materials technology is a major factor driving this growth. Traditional materials promote the growth of low-power LED lighting market, and high-performance products, such as silicone materials help solid-state lighting products to cope increasingly demanding in the rapid developing Chinese general lighting market. Dow Corning Electronics Industry Solutions Division Vice President Eric Peters (Eric + Peeters) pointed out that "Chinese rapidly growing market increasingly demand on general lighting board chip package structure, which expand the actual performance of the traditional glass ring epoxy resin and plastic packaging materials to the limit. Currently, the industry's interest silicone materials is growing, including the constant pursuit of higher performance, and constantly improve the LED temperature performance, continuing to explore more design space, continue to cut costs. Peters said: "The needs of these emerging markets will not hinder that China develops a new generation LED lighting products, but in China, succeed in the highly fragmented and competitive market requires that designers, manufacturers and materials developers work closely together. "

LED Lighting has now entered the stage of rapid development, it will quickly occupy the leading position in lighting maket the next few years, and now the power LED flood light, LED tunnel lights, LED tube, etc. have already been used in commercial scale and decorative lighting and home lighting to replace the traditional fluorescent lighting, while there have been a large number of professional LED manufacturer, Lead lighting is spearing its high-quality lighting and low prices to the world, Lead lighting Home page www.lead-lighting.com specialize humanity professional design that allows us to understand more detail in the scope and application of LED performance, and let us together with lead lighting create more energy saving world.

Why do we popularize LED lighting especially in China？

Mainly in three aspects.

1.LED lighting promote the application in the city. If considering only 657 cities nationwide municipal lighting (not including about 2,000 counties and about 20,000 small town)，there are 17,740,000 municipal road lights, the number of LED flood light and other landscape lighting is huge. Because China is in the urbanization high-speed development period，the urban population annual increase more than 10 million, the number of street lights will grow 120-150 ten thousand, and this process will continue for 25 years or even 30 years. If the city's new street fill with LED, replacing part of the old street lamps and landscape lighting with LED lighting, of which potential and development prospects can be imagined.

(2) to promote LED lighting in residential building. China is a big construction country, there are 2 billion square meters new construction per year, which is equivalent to half of the world's new building in China, where at least 20 lights must be needed in each building unit; coupled with the "Twelve Five" period, the government pays to build 36 million units affordable housing, about 5-6 one hundred million LED lights will be potentially applied.  The  construction area that has been built in the city is ​​more than 200 million square meters, according to expert estimates, if using 30% of LED lighting, we can save more than 1000 billion kWh. Compared with other energy-saving projects, LED lights has a huge potential, such as replacing the 50% of the national motor with high efficiency motors can saving 3.4 billion kWh of electricity, it is because that 10% energy saving is quite a lot for the motor. But replacing the traditional incandescent with LED， energy savings is 50% or more.

3. The potential applications is greater in the vast rural market. The most pressing is that nearly 20 million households are lack of less electricity, if these farmers use solar energy and LED integration, replacing large power grid, the annual electricity savings will also be more than 500 million degrees. If traditional power grid extends to those remote village, not only 75% of the electricity will be consumed on the line, but its maintenance costs is extremely high, the total investment is more than $ 50 billion. Household solar photovoltaic integrated LED lighting facilities, only 1,600 yuan， per household lighting problem can be solved, and very low maintenance costs. Coupled with  about 20,000 small urbanization towns accommodating nearly half of the population capacity，the market of promoting LED is huge. Thus, promoting LED is undoubtedly one of the main battlefield of our energy reduction.

China has a lot of professional LED manufacturers, especially in the coastal areas of the Pearl River Delta, Shenzhen Li Sida lighting is one of a photoelectric company, adhering to the professional environmental and energy-efficient LED lighting to adapt to our consumption demand，which has advanced the LED lighting illuminates to every corner of the world, Li Sida lighting www.lead-lighting.com is currently still trying best to contribution to low-carbon environment.

Safety starts from the LED Tunnel Light

Every time I take train, when the train shuttle in the tunnel, I have a kind of nameless fear, the longer the time is, the deeper this fear is, perhaps that’s why we fear the dark, and only at this time I have more profound understanding that how important the light is. Every time I see traffic accidents, I am very sorry, although many accidents occur not directly in the tunnel, the trains and other vehicles must pass through the tunnel, indeed, traffic accidents is closely related to the driver's fatigue driving. Of course if we choose lighting suitable for our vision, which will greatly reduce the driver's fatigue.

As an environmental enthusiast, I am very interested in green energy, LED lighting as the third generation of lighting use semiconductor as its luminous body, energy saving is the biggest characteristic of the semiconductor light-emitting, emitting soft and non-glare light, The LED tunnel light as a basis for the use of semiconductor lighting is known as high brightness and soft light. As we all know, many drivers are used to long-distance driving, motorways and the tracks often pass through tunnels, and driver are exhausted after of driving a car and the train for one or second days. The dazzling lighting undoubtedly affect their vision and aggravated their fatigue in the tunnel, if we choose this high brightness and non-glare LED tunnel lights, which can effectively solve this problem.

 

I also surely chose LED lamps for indoor lighting, stable and soft light indeed is suitable for learning and working, and monthly tariff reduction is from the previous fifty or sixty to now two thirty, the LED tube was introduced by my friend Jack who is working as engineer，they have been using LED lighting for the site lighting, LED floodlighting are currently  widely used in the stadiums, squares, parks lights outdoor lighting place, they have been cooperating with a LED lighting manufacturer , which provides quality LED floodlights already have been used for more than two years on the construction site, and their attentive service ensure the product timely replace unless man-made damage, so he recommended me to use their LED lighting , I didn't decide to buy the LED lamp from the company until I viewed this company's homepage www.lead-lighting.com, so user-friendly design and detailed product descriptions that I can’t help admiring professional and attentive of this company’s staff, , LED tube ordered with friends does not appear any problems nearly a year later.

If you are the engineers building the tunnel, I suggest you choose this company LED tunnel lights, because the company's products is  more professional and relatively lower prices compare to big brands at a high price, why do you still hesitant? Take action just for our safe!

The third key of limiting the popularity of LED light—quality

Reporters have an interview with some shops, although there are LED lighting selling in many shops, the majority are small brands and rarely big brands. Some small brands of products are manufactured comparatively roughly in some detail, vaguely marked on the product text, making it difficult to identify, although retail sales staff said that these LED lights can be used normally seven years, but looking at these bulb it is hard to confirm its quality. there are customers into shops to buy lights jewelry from time to time, but the choice of LED lighting is relatively small, why the customer does not trust is that they unlikely to understand the LED product, one is expensive, and the other is there are some problems with the quality, as like the customer said: "You can use more than seven years on business, but what hard to say is that whether is the case."

LED lighting products have to give us confidence to enter the homes of ordinary people, the immediate priority must be to improve quality and brand image. Although LED lighting products sales on the market, the quality issues also have always been. Some consumers buy a LED bulbs and have to come back to change just for a week, the paid the price but did not enjoy the corresponding services, they will generate resentment for such products, it would be difficult for the brand to set up. Fortunately many companies have a profound understanding of this point.

Quality is fundamental to establish a brand, but the wine is also deeply afraid of the alley, you must put your own branding to go out, strengthening channel construction has become the consensus of many LED companies, which has become an important direction for LED business Because interior lighting directly face to end customers and consumers, so the importance of channels is highlighted. It can be said that who mastered the channel, who will seize the initiative in the indoor lighting market, many companies have started building in the channel force. Reporters found that many LED lighting companies played the investment advertising at the show,,. Some of the leading LED enterprises with strength also increase invest channel to find the right franchisee this year, and select a number of high-quality seller channel for cooperation to open interior lighting market.

Li Sida lighting stick with qualified LED chips and LED light source and other LED materials and eliminate all inferior materials, so people is assured of LED lighting, LED flood light and LED tunnel lights and other commercial lighting has long been out of the country into the European market and has been well received, Li Sida lighting www.lead-lighting.com is continuing its efforts to develop more environmentally friendly LED light that is suitable for ordinary consumer groups to spread it to every corner of the world！
