The development of new LED street light has a considerably important significance on urban construction

Outdoor lighting including: Lawn lamp, garden lights, tunnel lights, flood lights, underwater lights, street lights, wall lights, landscape lights, buried lights., which are known as the power, strong brightness, bulky, long lifespan, low maintenance costs by comparison with home lighting.

  

Currently, the LED street light is highest applications of outdoor lighting. Los Angeles plans to install 140,000 LED street lights during five years, while all of the street lights in the Pennsylvania Ambler and Sunbury city are about to be replaced with LED street lights, LED street lamps are also significantly commonly used in other countries, such as UK,German,Japan, Korea and so on. In China, Dongguan city plan to replace all of the road lighting with LED street lights within three years, Hainan plans to achieve within five years. The infrastructure construction of Beijing Olympic Games, Shanghai World Expo and Guangzhou Asian Games also makes extensive use of LED outdoor lighting, such as 70,000 LED street lights were installed around the main stadium and the surrounding roads of Guangzhou Asian Games venues, , 12,000 high pressure sodium lamp were all transformed into LED street lights  on 12 main roads surrounding  Foshan Lingnan Pearl Stadium arena .

   

There is no doubt that street light is an important part of urban lighting. The traditional street lights are often high pressure sodium lights, the low overall light efficiency of pressure sodium lamp causes a huge waste of energy, therefore, the development of new LED street lighting with high efficiency, energy saving, long lifespan, high color rendering index, environmentally friendly has a considerably important significance on urban construction.

What’re the working characteristics of fluorescent lamp and differences between LED tube and fluorescent lamp

There is filament at each end of the fluorescent lamp, the lamp is filled with traces of argon and thin mercury vapor, the inner wall of the lamp is coated with a fluorescent powder, the gas between the filament at each end of the fluorescent lamp will emit ultraviolet when the gas is conductive，making that phosphors emit soft visible light.

Working characteristics of fluorescent: The lamp requires a high voltage to light up, which only allows through lower current when the lamp normally work, the voltage across the lamp is lower than the supply voltage.

Both ends of fluorescent tube is filled with the filament, the inner wall of the glass tube is coated with a thin layer of uniform phosphor powder，the tube is evacuated to a vacuum and a filled with small amount of inert gas, while being injected small amounts of liquid mercury. The inductor ballast is core induction coil, when the current in the coil is changed, the change in the magnetic flux is caused in the coil, thereby generating an induced electromotive force，the direction of which is opposite to that of the current, thereby hampering the current changes.

The starter in the circuit is playing as switch, which consists of a neon discharge tube in parallel with a capacitor, the capacitor is to eliminate electromagnetic interference on the power supply and form the oscillation circuit with the ballast to increase the amplitude of the pulse voltage started. A electrode in the discharge tube is composed by the bimetal, by discharging and heating the neon bulb induce the mutations of current through on the inductor ballast so that produce a high voltage pulse applied across the lamp，when the bimetal is opening and closing.

When the fluorescent lamp access to the circuit, the starter between the two electrodes begin to glow and discharge, then the bimetal expanded because of thermal contact with the stationary pole, so the power supply, ballast, starter and filament form a closed loop，the current preheat the filament, after being heated for 1-3 seconds， the starter between two electrodes do not glow any more, followed by cooling bimetal disconnect with the stationary pole, , the ballast produce a high-voltage pulse as soon as the electrodes are disconnected and the circuit current suddenly disappeared, so that the inert gas inside the lamp is ionized and cause arc discharge, the ballast inductance also plays a role in stabilizing current in the circuit.

   

LED tube light uses the LED as light source and work at DC current，which do not contain mercy and phosphor powder and is known as environmental friendly, long lifespan, energy-saving and wide projection angle adjustment range, the 15W LED tube light is equivalent to ordinary 40W fluorescent lamps. LED tube light withstands high temperatures and is famous for moisture and waterproof, leakproof. There Voltage: 110V, 220V available, the cover is made of glass or PC material.

LED tube light uses the latest LED technology, 12W LED tube light is equivalent to 40W fluorescent tube (for ballast and starter, the real consumption power of 36W fluorescent is 42W to 44W). The lifespan of LED tube light is 1.5 times more than that of the ordinary lamp, there is no need to frequently replace the lamp, ballast, starter. The LED tube light with green semiconductor light source and soft light, pure spectrum is in favor of protecting our eyesight and physical health. The cool 6000K cool white light gives us comfortable vision,, user-friendly design of illumination differences also helps us to focus and improve efficiency.

How to choose LED lamp is based on the appearance and energy saving effect and price

The appearance and weight of LED lights especially commercial LED lamp including LED flood light can be used as a reference to determine whether the lamp is good or not. Brand  LED lighting products focus on the appearance to give us a better impact，so the LED flood light and other commercial and industrial and household LED lamps with exquisite workmanship, compact assembly, clear identification is generally qualify, because the quality appearance of LED lamps is actually related to the industrial design and abrasives invested by the manufacturers， in addition, the LED flood light and other outdoor and indoor LED lamps require dissipating heat, massive of poor shell is made of ordinary plastic to reduce costs, the entire product is so lightweight that are generally relatively poor product quality.

    

Energy saving effect and long lifespan are the advantages of LED light, considering the energy saving effect, for the the LED flood light and other outdoor and indoor LED lighting products, luminous efficiency (lumens / watt, lm / W)) is proportional to the energy saving effect， the higher the luminous efficiency, the better the energy saving effect. We who mainly rely on the product or the power to determine energy efficient are currently not very familiar with LED lighting effect, lots of small brands mark fake power and lighting effects to attract customers，the best way is to believe the brand and go to the regular place to buy.

Price is an important factor when we choose the LED light, but there are so many kinds of LED lighting product including LED flood light and other commercial and industrial and household LED lamps that the price can not be generalized, it is difficult to judge whether it is good or not. The current prices of LED flood light and other commercial and industrial and household LED lighting have been significantly reduced compared to previous years. For example, according to price trend of LED bulb of several major brands tracked by Taobao network terminal from CSA Research, the price of LED bulb/ power has declined from 8.08 yuan / W to 6.10 yuan / W from August 2013 to March 2014 , a drop is 24.5%.

What are the mechanical components and structures of LED lamp

By designing the structure， The mechanically is to determine the relationship between the position of the lamp and the optical system, the electrical system and the heating system, so that the lamp can be fixed in the secure setting environment.

   

The mechanical system of traditional lamp is composed by the fixed light source， reflector, control devices , the flexible cable or cord, sealing structure, mechanical protection structure, lighting fixtures fixed structure and regulation structures and other structures, which are specifically the lighting source and lighting connectors，as well as the lamp socket and holders mounting bracket, cord holder, terminal Block, housing, lampshades and mounting bracket and so on. Due to the characteristics of LED light sources especially household LED lamp including LED ceiling light, there are several kinds of LED lights，including package, module, LED light engine, integral LED lamps, non-integral LED lamps, in addition the internal structure of integral and non-integral LED lamps is similar to that of the traditional lighting fixtures, LED ceiling light and other household and commercial LED light with no standard lamp have following structural features:

LED ceiling light and other indoor and outdoor LED lamps do not have lamp holder, but the connecting member is used to connect the LED lighting source and light fixture, and adopt other ways to fix the LED lights on the lamp body.

There are a large quantities of heat sink to derive the heat generated by the chip of LED ceiling light and other household and commercial LED light, which are generally much bigger and heavier than conventional light fixtures, lamps mounting structure should be considered accordingly to ensure the safety and reliability of the installation. Meanwhile heat sink should be designed to be easily cleaned, otherwise the fin efficiency will soon be reduced.

The power cord and the power cord  LED ceiling light and other household and commercial LED lamp use  are removable for maintenance, a non-Z-type connector is the same as the Z-type connector of non-traditional sources, LED lamps should also use cord holder.

Japan built the world’s largest LED vegetable factory

Recently, Taga City, Miyagi Prefecture, Japan built the world’s largest LED vegetable factory that can produce 10,000pcs lettuces every day. Vegetable production has increased by 5 percent due to the use of LED grow light.

   

Previously, LED grow light are accustomed to emitting linear light, a large quantities of LED grow lights need to be installed for a large-scale radiation, which makes the cost of production significantly exceeded，it is difficult to earn profits. And the plant is currently adopting the new technology developed by the General Electric Company，which overcomes the LED grow light’s linear light and can be allowed to produce a wide range of scattering of light, and also issued several light waves promoting photosynthesis and plant growth, when the plant is planted, the new LED grow light can be used separately, depending on the growth stage, including “seedling stage”, “harvest”, etc., and the power consumed by this new LED grow light is lower by 4 percent.

In Japan, there are many vegetable plants using artificial light sources, LED grow light is also not uncommon, but most of plants are unable to adopt all of the LED grow light because of cost issues, which  use a mix of LED and fluorescent illumination.

The vegetable plant operators Mirai company expects the plant will provide the supermarket of the prefecture with vegetable, which is priced at 200 yen (about 12 yuan), the annual sales is expected to reach 300 million yen (about RMB 18,250,000 million).

How to design football field lighting

Football is a highly confrontational collective athletic events, which is widely popular sport in the world. The history of the development of football is sufficient to explain the vitality and influence. In accordance with FIFA, the length of soccer venues is 105 ~ 110m, the width is 68 ~ 75m, there should be not an obstacle 5m at least within the bottom line and the outer edge course to ensure the safety of athletes.

   

Soccer field lighting is divided into indoor football stadium lighting and outdoor football stadium lighting, which lamp should be installed depends on the venue. How to determine the standard is based on the features of the football field, which is divided into seven levels, training and entertainment illumination 200lx, amateur competitions 500lx, professional game 750lx, general TV broadcast 1000lx, large-scale international competitions HD television 1400lx, TV emergency 750lx.

   

The 1000W, 1500W metal halide lamp or spotlights used to be adopted as traditional football field lighting, because there are high-energy, short life, inconvenient installation, poor color rendering， the insufficient actual brightness and other shortcomings, which has been difficult to meet the lighting requirements of modern stadiums.

The LED lighting especially high power LED flood light on top of the football stadium venue should have enough illumination so that athletes should avoid causing glare. The pole lamp or high power LED flood light are generally used in soccer field, which can be installed on the edge of the stands roof, or mounted on top of the pole mounted around the stadium; how many LED flood lights and pole lamps should be installed and how to arrange them shall be based on the different requirements of LED lighting in different soccer field.Browsing http://www.lead-lighting.com/products/sid124-1.htm for more information about high power LED flood light.

How to arrange lighting

Identify our needs. How to arrange lighting depends on our lifestyle. So, we need to develop a home lighting plan to meet what our family need. When planning our lighting, we need to analyze the type of activity in each room, the atmosphere we want to create (light and dark, light and shadow, modern and traditional and so on), the decor elements we want to emphasize. Remember, the light will be absorbed and wasted in a dark room, which is differently for a light colored room, the light is reflected and wasted. In addition, I want to emphasize is that if there are a variety of activities in a room，for example, the living room，a variety of ways need to be set to meet different lighting illumination.

The first way of lighting: general lighting

   

General lighting provides an area with overall illumination，which is ambient lighting mentioned by the designers，general lighting provides a comfortable brightness, ensuring the safety of walking so that we can see the objects. Which light we should use? Don’t worry, we can use ceiling lights, wall lamps, embedded lamps, track lighting, and even adopted the use outdoor lighting. General illumination is the most basic lighting we layout.

The second way of lighting: task lighting

   

Task lighting is to help us to complete specific tasks, such as reading in the library, and washing clothes in the laundry room, cooking in the kitchen, playing video games and so on. We can use the embedded lamps, track lamps, ceiling lamps, portable lamps. In addition we shall avoid glare and shadows when using these lamps, but there must be bright enough to avoid visual fatigue.

A third way of lighting: accent lighting

   

Accent lighting give the room to increase dramatic effect to create excitement. As an element of decoration, we can not only use it to light up paintings, sculptures, and other decorations, but also stress the material of walls or fabric (such as curtains)，which can also be used for outdoor scene lighting. For the accent lighting mode, the central illumination required is three times more than the surrounding. We can use track lighting, recessed light fixtures or wall lamp to meet these.

What do LED grow lighting make effect on plants

1. Different wavelengths of light make different effect on the photosynthesis, plants are different, the wavelength of light the plant need to photosynthesis is about 400-700nm. 400-500nm (blue) and（610-720nm (red)，which makes the greatest contribution to photosynthesis.

2.The light emitted by LED grow lighting is a combination of two colors. For the visual effect, the combination of red and blue lights shows pink.

3 blue light promote leaf growth; red light helps to prolong flowering and fruiting and flowering!

4 When LED grow lighting pour light to a plant，the gap between the leaves and LED grow lighting is generally about 0.5 meters, which continuously illuminating for 12-16 hours a day can completely replace the sun.

        

The advantages of LED grow lighting:

· Reduce cultivation costs, extend the flowering period

· Promote plant precocity, increase production, improve the quality of fruits

• Ensure the taste of greenhouse vegetables, to achieve in-season cultivation

· Inhibit bacteria and pests breeding, reduce the amount of pesticides, green and no pollution

What are the other five questions for the design of the LED tube light

1.What is the  relationship between PFC power factor and wide voltage of LED series-parallel?

There are currently three kinds of PFC power supply on the market: one is dedicated circuit without PFC, the PFC is generally about 0.65; one is with a passive PFC circuit, the light board match well, the PFC is generally about 0.92; there is PFC power supply with an active 7527/6561 circuit, which can reach 0.99, but the cost of this program as twice expensive as the second solution. So as The secondary program. For passive PFC circuit，which is also called a valley-fill PFC circuit, the operating voltage range is half of the peak voltage of the AC input. If the input is 180V, the peak is 180 * 1.414 = 254V, the half of the peak voltage is 127V, a step-down pressure minus is 30V, the maximum output is 90V, so the maximum number of series LED lamp is 28 strings. Therefore, to get relatively large power factor, the number of lamp beads series should be not too much, otherwise, it can not reach the low voltage requirements.

   

2, how much current precision of power supply of LED tube T5 and T8 would be the most appropriate?

some of precision constant current of power supply on the market is too bad, such as the popularity of the constant program, including PT4107/HV9910/BP2808/SMD802 programs whose deviation is ± 8% or ± 10%, the constant deviation is too large. General requirements is ± 3%. Deviation is 3%, for the 6 parallel, each of the deviation is about ± 0.5%, if the 12-way parallel, each of the error is about ± 0.25%, the accuracy is sufficient. Accuracy is too high, the cost will be greatly increased. And, 17 mA and 17.5 mA make little effect on LED.

3, isolated / non-isolated

The transformer of 15W isolated power placed inside LED tube T5 and T8 is generally bulky, it is difficult to put into the tube. Especially for T5/T8 lamp, so the LED tube T5 and T8 with isolated power is generally 15W, those exceeding15W are rarely, and the price is very expensive. So the cost of LED tube T5 and T8 with isolation power is not high, the non-isolated is generally more mainstream, the volume can be smaller, the minimum height is 8 mm.

4, power efficiency of LED fluorescent lamp

Output power (output LED voltage * Output current / input power). This parameter is particularly important，low inefficient means a large amount of the input power is converted into heat; If the power supply is installed in the lamp，which will produce a very high temperature, the temperature will be higher superposed. And the lifespan of electronic components inside the LED tube T5 and T8 will be shortened with increasing temperature. So efficiency is the most fundamental factor, deciding the life，the efficiency can not be too low, or the heat generated by power in too much.

5, power of LED tube T5 and T8

Height is the main limiting factor, the power generally used for T5 tube / T8 can not be too highly, which is ≤ 9 mm.Browsing http://www.lead-lighting.com/led-tube/t5-tube-smd-3014-series.htm for more information about LED tube T5.

What are the three key factors affecting the price of LED lighting products

1, the domestic enterprises without core technology

The vast majority of core patents of LED upstream industry lies in the hands of foreigners, China mainland lighting companies specializing in commercial LED lighting including RGB LED flood light and household LED lighting have not mastered the core technology, although the manufacturing capacity and share of China’s RGB LED flood light and other commercial and industrial and household LED lighting application products nearly account for 50% in the world, yet it does at least profits.

The main cost of RGB LED flood light and other commercial and outdoor  and indoor LED lighting mainly lies in LED chip, as long as chip prices decline, The price of LED lumen unit can be reduced considerably with that of energy-saving lamps. Because the LED chip uses larger wafers while the production process and the number are growing, which will continue to reduce costs, the lower rate is 20% annually in recent years, the decline in the price include the enhancing efficiency of LED chip, for the better product at the same price，there is still a great price cut for the LED chip.

    

2, it is difficult to dissipate heat for LED RGB LED flood light and other commercial and industrial and household LED lighting application

The effective cooling design is very simple to maintain the 5% cooling cost, there are always two directions: First, the shorter the path of LED chip and the heat sink, the better the thermal design; Second, heat resistance , that is to have enough heat spread path while must also have sufficient “cooling path.” The main cost of this part is structure, which accounts about 20% of the  cost of luminaire，and there is not much costs for cooling. The biggest problem now is how to design more creatively and more reasonable RGB LED flood light and other commercial and industrial and household LED lighting.

3, LED power supply applications

Power is weakest link of led lighting, which restricts the development of LED lighting. The costs of design account for about 20% of that of RGB LED flood light and other commercial and industrial and household LED lighting now, with the technology development of power，about 5-10% cost is the most reasonable.

The cost of RGB LED flood light and other commercial and outdoor and indoor LED lighting is not high contrast with other lighting source，in fact, especially LED lighting is known as environmental protection, energy saving, no mercury, and the price of LED lighting are sliding down at every quarter, The price of RGB LED flood light and other commercial and industrial and household LED lighting will be able to reach an acceptable level of people in a relatively short period of time.Browsing http://www.lead-lighting.com/led-flood-light/led-flood-light-rgb-series.htm for more information about RGB LED flood light.
