Analysis of LED street lamp Market in 2010

With ten city lights of semiconductor lighting project started, and the demand for energy saving and environmental protection is more and more high, our country basically determined to LED outdoor lighting as the main direction. Among them, the LED street lamp has attracted much attention, the government as an important starting point for the introduction of lighting applications market. In the LED chip and packaging technology continues to progress, LED has become a leading lighting. More and more countries have formulated regulations and Standard Specification for carbon reduction and energy saving lighting, which not only contributes to the development of LED lighting applications market, also means that the LED lamp will immediately become a master of technology innovation in the field of road lighting. LED street lamp will become the new favorite of the road lighting market with its excellent environmental protection, reliability, energy saving and the characteristics of aesthetic design.

Analysis of domestic LED street market size

Estimates, with the global economic growth, the global lighting market will show the trend of increasing year by year, in 2010 the global market size of up to 1.6 to 180 million street lights around.

The development speed of 2009 LED lamp although not as fast as expected, but it will replace the traditional street lamp, it is beyond doubt. Now a lot of LED companies competing to invest in R & D LED street lamps, there have been hundreds of LED street lamp products, but most have not achieved mass production. Compared with the enthusiasm of LED street lights, in 2009 China's LED street market has yet to force. According to statistics, in 2009 Chinese LED street market size is only 20-30 million, in the next few years, ten city lights, one hundred thousand lights and other slogans Trinidad policies, Chinese LED streetlight market still maintain a rapid pace of market development, is expected to 2012, the market size in 2008 will be 560 million yuan growth to 3 billion 960 million yuan, the annual compound growth rate of 63%.

LED Street cost competitive advantage

Although LED street is still 3 times more expensive than the price of high pressure sodium lamp, but the overall power consumption and maintenance costs and other factors, after 2 years of use, the total cost is equal to almost LED lamp and high-pressure sodium. Therefore, in the long run, the cost of LED street lamp will be better than the current high pressure sodium lamp. To 8 meters of LED street lamp and high pressure lamp, high voltage lamp power consumption of about 250 watts, LED only need to be 60 watts, in the service life of part, high pressure sodium lamp on average about 4000 hours, but LED can be up to 50 thousand hours. With the continuous decline in the price of LED street lamp, its competitive advantage will become more and more obvious.

LED street light use efficiency

The luminous efficiency of LED high. At present, the light efficiency of LED can be purchased up to 100lm/W, and its light effect is much higher than that of energy saving lamp, metal halide lamp and electrodeless lamp, which is higher than that of the high-pressure sodium lamp which is commonly used in street lamp lighting at present. 10%. As a result, LED has now become one of the most luminous light sources. Using LED instead of incandescent lamp, fluorescent lamp, metal halide lamp and high pressure sodium lamp and other light source is no longer a big technical obstacles, but a matter of time.

LED streetlight technical problems development

With the LED lighting market blowout in the market, the development of LED lights gradually clear.

Many companies have vied for LED street market situation out of control. Although the LED industry has developed rapidly in recent years, but it is still a lack of authoritative technical standards, resulting in the industry as a whole, good and bad, for a wide range of promotion is very unfavorable. In the relatively high degree of technical difficulty in the LED street lamp, the lack of technical standards is particularly evident. Many of the technical excellence of LED manufacturers and integrators, do not know how to design a practical street lamp, the application can not clear the specific requirements of the department. For example, many manufacturers in order to solve the problem of LED heat dissipation, the design of a hollow type lampshade. But for street lamps, this style of "rain" function is not suitable for street lamps.

Light source, heat and power system still needs to be improved

Although in the government's strong support, the LED lighting market is growing fast, but can not be ignored, in order to obtain long-term development of real LED street market is still facing severe challenges. At present, in addition to the high cost, the main problems of LED street lamp products include: light source, heat dissipation and power supply system.

From the source point of view, on the one hand is the need to further enhance the luminous efficiency of LED, on the other hand, is to improve the arrangement of light source. At present, the market of a large part of the LED road lamp, LED light source is arranged through the lattice structure, the biggest advantage of this method is to solve the problem of heat dissipation, but this structure due to the horizontal irradiation distance is not enough, the light distribution range is larger, so it cannot achieve the centralized distribution of light reflecting cup, the need to achieve independent light distribution the two lens, the two lens for the material requirements higher, at present the two lenses of different materials have some problems, affect the use effect of the product. If the treatment is not good, the lens will also affect the lighting effect and clarity.

In order to improve the above problems, some enterprises have introduced the use of LED lamp light source module integrated mode, the source package reduces the circuit board welding and finished at work due to the emergence of a light source arranged or several road products lack of light. In addition, the utility model can realize the centralized light distribution by using the reflecting cup, and can also avoid the negative influence caused by the use of the two lens. However, it is undeniable that the use of such packaging light source will face a more severe heat challenge.

From the power perspective, different from the traditional lighting products can be directly connected to the AC power and LED are low
