What is the classification and characteristics of LED lights

LED floodlights and LED tunnel lights or LED high bay lights are used outdoor , LED ceiling light, LED spotlights and LED tube or LED bulb are used indoor. LED light is know as energy-saving and environmental protection. Why LED light has energy-saving and environmental effects is because that it uses semiconductor as lighting source, which has the advantage of greatly reduce the current waste into heat, compared to incandescent and fluorescent lamps, the efficiency of LED light is up to 30 %, while fluorescent is less than 20%， incandescent less than 10%, the United States,Japan and other countries and Taiwan of China's has been predicted energy-saving benefits of LED lighting. If in the United States 55% a of the incandescent lamp is replaced by LED ，annual savings is $ 35 billion and reduce carbon dioxide emissions by 755 million tons. In Japan, 100% of the incandescent is replaced, can reduce the generating capacity of I ~ 2 nuclear power plant, annual save consumption of more than one billion kilograms of crude oil. Japanese estimates, with half of its LED replacement of incandescent and fluorescent lamps, annual savings is equivalent to energy of six billion liters of crude oil. Such as Taiwan, China ，25% and 100% of the incandescent lamp is replaced by white LED, annually saving 11 billion kWh of electricity. 

Moreover, I can explain why LED lighting has environmentally friendly effect, the traditional incandescent and fluorescent lamps all contain mercury and other heavy metals, abandoned will pollute the air and water, and the LED lights do not add any heavy metals, Based on the use of semiconductor light, it does not pollute the environment , followed the traditional incandescent and fluorescent lamps adopt alternating current discharge, the changing frequency of the AC inevitable lead to stroboscopic effect that stimulation human eyes ，the tungsten in incandescent light and inert gas in fluorescent emission result in a lot of infrared and ultraviolet light that caused light pollution, while LED lighting adopts constant current driver at low-voltage so that it can convert the AC into DC luminous point, not only has no flicker, but also greatly reduces the infrared and ultraviolet. 

As an environmental enthusiasts, I am always insisting on using LED lighting, although the price is relatively high compare to ordinary bulbs, but the savings in lighting costs each month greatly exceeds the extra costs, Above all，unique structure of LED lights especially LED flood light ensures it has longer life than incandescent and fluorescent lamps, the most important is obviously that the LED lighting saves large amount of energy, it has been contributing to low-carbon environmental protection, of course, good LED products need professional LED manufacturers to complete, I have been choosing Li Sida lighting, whose website is www.lead-lighting.com, this company has relatively mature technology and welcoming service that is ahead of other companies, on my recommendation, a lot of friends who construct project and need LED floodlights for outdoor lighting and LED tub for interior lighting have accepted my opinion, unanimously approved after use.

LED floodlight installation tips and precautions

Although it is easy to be installed for LED floodlight, but there are some installation tips that need to be payed attention to, it is the supplement for advantage of the LED floodlight.

Buy lamps with screws, installation is relatively simple, elaborate below: the material needed to use: LED guardrail lamps clamp, the transformer with waterproof function, sub-controller, follow these steps:

1, install the fence, punching on the wall, arduous according to actual requirements, generally within three centimeters,

2, good anti-static measures, such as bench should connect to the ground, the workers wear appropriate static clothing, the different grades of LED floodlights has different quality result in different anti-static ability of strength and different anti-static measures.

3, Installation sealing, poor sealing directly affect the service life of LED floodlights

4, LED flood light wiring is preferably not more than 25 cm, large power transformers can be correspondingly longer, otherwise affect the brightness

LED Floodlight Installation Precautions

1, try to use series LED patterns, because the LED floodlight voltage has special difference. Normal LED peak current is maintained at 80 mA, reverse voltage at 6V and down, we should pay attention to design the peak voltage and current during the limit

2, using under 25 watts voltage when welding, electric iron alone control 300 degrees Celsius under high temperature bare SMD LED, do not squeeze its part epoxy, or use sharp or hard objects to clean, because the LED lamps is very fragile, easily damaged, welding time under three seconds.

LED floodlights are widely used, so installation and precautions is very important tips, LED is the new light source, in the correct methods of installation is to ensure long-term stability of LED floodlights work..

Li Sida Lighting www.lead-lighting.com is always providing excellent products and detailed installation, considerate and humanity services won compliments and a series of honors and is popular in by Chinese and foreign customers 

Don't be mislead by these mistakes when selecting LED floodlights

The market of LED floodlights lighting is variety, such as explosion-proof floodlights glare floodlights，it is very large to choice for consumers, many selection methods is unscientific, the following interpretation is to help consumers avoid mistakes when purchasing floodlight .

1, select cheap floodlights, take the same type of lamps for example, the different price may be nearly doubled, consumers often demand cheaper, while sellers are used to displaying poor quality lamps that prices is low to attract. This is not correct, low-priced products tend to be low-level, why we use LED floodlight is intended to environmental protection, long life. Although origin and brand is not the same, indeed there is big difference between the power driver and chip, moreover， the quality of lamp beads directly affects the lamp brightness, low quality LED floodlights consume large amount of power，the heat is severe and insecurity is higher.

2, the decorative effect  Many consumers choose LED flood light based on the exterior but ignoring quality, partly because we did not know how to identify, basically, we should look for product specifications and certificates in the product packaging, and other basic accessories , the appearance of lamps is currently colorful, unique, we mustn't refer to salesmen when buying so-called evidence and no certificate of delivery, these lamps tend to come from small workshops, there is no guarantee safety and quality, it is the best way to choose the big brands, such as Philips and so on.，Li Sida lighting is devoted to adopting higher quality of chip and better light source to manufacturer  more professional LED light，which can be confirmed by browsing the product characteristic in www.lead-lighting.com and acknowledgement from the consumer.

3, the most high-power 

Misunderstanding is that lighting effect of the lamp is power, in fact, what decide lighting effects of LED floodlight is flux, the bigger is the power, the more unnatural is light, we must ensure how much is luminous size of flux, you can view the manual, the quality of light beads, luminous flux and power driver are different, , please be careful of differences when selecting.

Why do we choose LED flood light instead of others

LED lighting adopts semiconductor lighting, effectively avoid emission large quantities of heat, which is produced by the tungsten in incandescent light and inert gas in fluorescent light, resulting in less heat and making great efforts to solve the bad bulb bursts that caused by heat or even fire. Moreover, semiconductor lighting does not emit large amounts of infrared and ultraviolet light, which contains in light pollution caused by incandescent and fluorescent seriously and have severe influence on the atmosphere and people's daily lives, LED lighting commonly used low-voltage constant current driver that directly convert power the AC into direct current, thus solving strobe that irritate the human eye because of AC luminescence ，no harm to the human eye

As an environmental enthusiast, I also strive to practicing action of low-carbon environment, the annual Earth Hour promote energy-saving, but we can not turn off the lights all the time at night, so LED lights with high energy saving is essential  My friends Susan is working in a city planning bureau, where she is primarily responsible for her county lighting plan, since the adoption of LED floodlights for urban plazas, parks and public places, the institute hall lamp lighting，with LED light’s help， the county has efficiently reduced trouble in  financial repair and maintenance of investment and manpower, she also bought a LED lamp to decorate in the apartment. In her recommendation, I have just renovated courtyard, also bought LED floodlight for lighting, indeed LED flood light really help me save the cost of electricity and avoid trouble of replacement！ LED flood light has bright, wide light and is unlike incandescent as glare. Their county planning need a lot of cheap but good quality lighting because of their large-scale renovation project, they had to looking for a long time and refer lighting and fortunately they found a professional LED manufacturer and made a agreement due to friendly service and on-time delivery, a large number of LED floodlights and street lighting have been used nearly a year, and now in addition there are few bad LED street lights，LED floodlight basically has nothing problem in stadium and park. Such high-quality lighting equipment is the first time they met, she recommended me this company www.lead-lighting.com, I did not hesitate to buy a dozen LED floodlights, I am very satisfied with the less than one weeks delivery and considerate service .

Obviously, LED lights have attracted the world's leading electronic products Apple’s attention, and why he has so such charm, in fact, he is not only known for their eco-friendliness, and compared with the traditional fluorescent light ，it can greatly reduces the stimulation of human eye，especially LED flood light in the outdoor decorative lighting is acclaimed for its wide brightness by the us, Li Sida photoelectric www.lead-lighting.com, with its more leading peer LED lighting technology ，has accounted for a place in the LED lighting market.

What kind of light bulb saves more energy?

Obviously，LED light is our best answer. Now it is so popular and widely used in our daily life， we choose LED light instead of any others，what is the unique advantage compare to other lamps such fluorescent lamp. Let me explain to you

As we all know，the LED light is the third generation lighting product  superior to any others  because it is special in energy saving and environmental protection. Why？It adopts semiconductor lighting, which is ahead of the tungsten filament in incandescent and inert gases in energy-saving lamps In the case of the same current, the heat can be converted less, it greatly improve the utilization of energy, that's why it prefers to save energy. The semiconductor does not produce unique infrared and ultraviolet light, greatly reduce light pollution, in the constant pressure driven conditions, it directly convert AC into DC, so it is different with fluorescent and LED lighting, energy saving lamps, which generated flicker by frequent changes in the frequency of the alternating current, stimulate the human eye, it can be environmentally friendly.

Now LED flood light is popular in LED lighting, it is widely used in outdoor landscape lighting, because it uses highly integrated COB as light source, ensure high lighting intensity relative to other products, its unique design lampshade octahedron and light design so that it can irradiate all directions, and the LED floodlight with high thermal conductivity aluminum alloy and high heat dissipation lamp body inside the spray material, lampshades made ​​of high quality tempered glass, all of these features bring that LED floodlights is major in shock-resistant  and heat-resistant, waterproof and dustproof and good freshness, radiation characteristics, therefore it is widely welcomed in outdoor lighting, such as squares, parks, stadiums, airports, operating table, aerial vehicles, stage, tall buildings, etc. in vitro need to use LED Floodlights.

With the LED lighting is hot on the market, more and more enterprises have been taking participate in the LED lighting. Often a handful master the core technology, Li Sida lighting www.lead-lighting.com is one of a representative. Excellent quality and professional R & D and manufacturing staff  are devoting their effort to create more leading peer LED lighting

Why is LED light so popular in lighting industry

(1) LED lighting has been playing a huge role in energy conservation, single LED power is only 0.03-0.06W, and has low driving voltage (1.5-3.5V), current is small (15-18mA), under the same lighting effects, power consumption is only one-eighth of incandescent, fluorescent half. We can see that using the LED light source instead of incandescent and fluorescent lamps for landscape lighting which consume large amount of electricity, the energy saving effect is very obvious, with strong market competitiveness. And the LED light source life is 100 times of incandescent, fluorescent 20-30 times, eliminating the puzzle over needing frequent maintenance, furthermore it has rich colors and good controllability，nothing is better than the urban landscape lighting. Now, LED has increased by  a 50% rate to replace the traditional light source, it will lead the fourth time in the history of mankind lighting revolution, which greatly improve the human environment, alleviate the increasingly serious global energy crisis.

(2) LED light source structure has light weight (epoxy resin), compact, able to adapt to a variety of different geometry and size of the space, light is solid, not inflated, there is no gas sealing problems, no glass enclosure, resistance Shock, shock-resistant, not easily broken, determines that the require of its strength and stiffness is low than other light sources. Moreover, LED has cold light source, controllable, fast response time, can be repeated frequently turn on and off, not tired. LED tube is the best example to illustrate these advantages

(3) LED light color is pure, rich, can evolve any color, the color is better than metal halide lamp, and its decorative is unparalleled. LED flood light is the best lighting which apply in the decorative lighting. LED light source is compact so that it has  good flexibility, can form a variety of point, line, surface, balls and other shapes. According to the purposes of landscape lighting， with the help of the microcomputer intelligent control technology, the changes of LED light source can be made into what is suitable for point, line, surface, the ball, and other forms, including: Flicker (flashing) control, suitable for the formation of "point, line "; gradual (soft change) control, suitable for the formation of" side "; dynamic variable (jump) control, suitable for forming a pattern vertical and horizontal movement changes. These three changes can also form a sphere rotating movement, also can be a single lamp control and light control group.

Of course, everything is not perfect, LED lighting is no exception, its price is currently slightly high compare with conventional lighting equipment, and he needs constant current drive and excellent heat dissipation configured to support, relatively low CRI.

With increasing demands for energy saving, environmentally conscious are getting higher and higher, LED lighting has been extensively used in people's daily life, at same time, LED manufacturers have also took part in the lighting industry, but professional LED manufacturer is few，Li Sida www.lead-lighting.com is one of a photoelectric, he is leading the industry to create the highest quality LED lighting and the most appropriate price for the public, and his excellent sales and delivery has been greatly praised by users at home and abroad ,he together with us is fully committed to save energy and protect the environment. 

Illuminate the road to warm our heart

The city's street lights are to illuminate the road，however，it brings a lot of light pollution and energy waste, it has long been heavily criticized but no good solutions. The media recently reported that a group of researchers from China, Taiwan and Mexico developed a new lighting system, the efficient useful of LED ensure that street lamp illuminates where only need light, without creating unnecessary light.

We often see the light and dark areas of the road serrated distribution on the road lighted by ordinary street lighting especially on the narrow road. The traditional way of lighting is not only inefficient, but also result in a serious light pollution. The study found that more than one fifth of the traditional street lights energy are wasted by levels and upward light.

"A unique feature of this new LED system is its ability to adapt to different street street layout, efficient lighting for a variety of streets and roads," China Taiwan Central University involved in the study of electro-optical and Engineering Professor Sun Qingcheng said.

This new street lighting system consists of three parts. The first part contain a string of light emitting diodes, each of them is equipped with the apparatus called a lens of total internal reflection (TIR), and it can pooled light and precisely control the light beam direction so that the light emitted in parallel without mutual cross. These lens is mounted in a reflector cavity, the recycling of light ensure that they can be used to illuminate a target, which is the second part of the system. The third part is the outermost layer of the light filter means, its role is to reduce unwanted glare. Through this unique structure, the researchers were able to control the shape of the beam, the preliminary design of the beam is rectangular in shape, very suitable for road lighting. 

The researchers used light utilization (OUF) to quantify the performance of the street lamps, the LED road light utilization efficiency is higher，the light performance is better. The computer simulation results show that this new type of street lighting system light utilization efficiency can reach 51% to 81%, far more than 45% of the ordinary street. In addition, compared with the traditional street lights, this new lamp brightness is higher, more energy efficient, easy to produce glare and light pollution.

The researchers said that due to the design of simple structure, the use of ordinary LED bulbs can be easily modular assembly. They prototyping, is expected to be completed within next 3-6 months, the actual installation experiments would be done on the road early next year. More professional user-friendly website www.lead-lighting.com is to create a more perfect LED lights.
