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.

The demand for high power LED light will increase to $ 27 billion pcs

Market research firm NPD Display Search estimates that the compound annual growth rate (CAGR) of shipments of high power LED lights including LED street lights，direct type LED backlight, LED spotlight and other LED applications with high-brightness will reach 13% from 2014 to 2017; Quarterly LED Lighting and Display Supply / Demand Report predicted that the demand for high power LED light will increase to $ 27 billion in 2017 from 18.5 billion in 2014.

  

LED street light applications will occupy 28% of total shipments of high power LED lighting in 2014, followed by TV LED backlight and LED spot light, each accounting for 27 ，NPD Display Search forecast LED street lights will dominate the market share of high power LED lighting by 2017, followed by LED spotlights (21%) and TV LED backlighting (15%).

Although the prices of high power LED lamp is relatively expensive over that of low power LED lighting, but considering the cost structure in the street light, LED street light occupy only a small part of the total cost of the street lights, most manufacturers are using high-power LED street lights with better reliability to achieve the high reliability and performance requirements required, thus promoting a growth in shipments of high-power LED light. Moreover, with the rise in energy costs, high-brightness lighting demand will continue to grow to achieve energy efficient in countries.

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.
