In order to welcome the Guangzhou Asian Games event, the Guangzhou Municipal Government has invested heavily in the planning and renovation of municipal facilities. Among them, the focus of the lighting industry is that the Guangzhou Municipal Government has allocated a large amount of money to support the promotion and application of the LED lighting industry. It is understood that in order to do a good job in the Asian Games and fully demonstrate the urban style of Guangzhou, the Guangzhou Municipal Government will complete the energy-saving renovation of 40,000 existing street lamps, making the city's LED street lights expected to exceed 50,000. This shows LEDs to a certain extent. As a product of street light source, it also reveals that the strong development trend of LED street lights is unstoppable.
According to research by LED related industry research institutes, it is estimated that the number of LED street light fixtures in the world in 2010 is about 870,000, which is 42.62% higher than that of 2009. As far as China is concerned, the number of LED street lighting installations in China in 2009 was about 250,000 baht. It is estimated that by 2010, China's LED streetlight market will grow by 60% to 400,000 ç› or more.
In recent years, with the accelerating urbanization process in China, urban road lighting has become more and more closely related to people's daily life. The LED street lights that are efficient, energy-saving, green and long-lasting will enter people's field of vision in large quantities, becoming a "specified light" that illuminates the city's night sky and a starry landscape that can't be erased.
Compared with ordinary traditional street light sources, LED street lights show its undeniable advantages. For example, the most significant is the long life of LEDs. For example, the life of metal halide lamps is 6000~12000 hours, and the life of high pressure sodium lamps is 12000. Hours, and when the LED light flux is attenuated to 80%, its life can reach 25,000 hours; the light color and color rendering of white LEDs are better than high-pressure sodium lamps, which is beneficial to improve the chances of human eyes distinguishing things; LED can be reduced The method of small current is used for dimming, and the pulse width method can also be used for adjustment. Therefore, in view of the frequent switching frequency, it does not cause too much loss of the LED lamp; the LED is different from the conventional light source by using a full-space light source, but The semi-space illuminating light source can effectively reduce the light loss and improve the light utilization rate. In addition, the LED environmental protection performance is well known. The main point is that the LED light source does not contain harmful metal mercury, unlike high pressure sodium lamp or metal halide. The lamp is hazardous to the environment when it is disposed of.
In the Guangzhou City Road Lighting Reconstruction Project, the energy-saving renovation of LED street lamps is now at the national leading level. Driven by this, the urban road lighting application development market of LED street lamps is coming to the fore, and the urbanization of LED street lamps is bound to become a construction project that should receive more attention and support in the process of urbanization in China.
