The light source module is the future development direction of LED street lamp www.ledld.com.cn

The current lighting fixtures are: high-pressure sodium lamps, which is currently the mainstream of the market; metal halide lamps, due to higher prices, only a few to adopt; fluorescent lamps, a few use; LED, the current rapid development trend. It is possible for LED street lamps to achieve 30 to 40% energy savings through reasonable design.
At present, the main source of street lamps is high-pressure sodium lamps. The efficacy of high-pressure sodium lamps is as high as 120 lm/W, and the efficiency of LED light sources is 90 to 100 lm/W. In terms of light utilization, the luminous flux of the high-pressure sodium lamp on the effective road surface is about 40%, and the effective light utilization rate of the LED lamp must be more than 50% before it is possible to save energy. From the point of view of the life of the lamp, it is possible for the LED street lamp to reach a lifetime of more than 20,000 through a reasonable design.
However, due to the fact that existing high-power LED luminaires adopt an integrated integrated design, that is, the lamp housing is integrated with the LED device and sealed in the glass, which makes maintenance extremely difficult, and also affects the overall life of the luminaire. The development of LED technology cannot be standardized. 

Street lamp light source module is the main solution to solve these real problems. The idea of light source refers to the integration of a number of LED light sources in high-power LED lamps into a light distribution, heat dissipation, and waterproof and dustproof IP rating. A light fixture consists of several modules, not all of the original LED light sources. Both are installed in one fixture. The entire LED lamp consists of three components: a lamp base, a light source module, and a driver. This is the same as a lamp with a conventional light source. The module is waterproof, light distribution, heat dissipation, easy removal and other functions. In this way, high-power LED lighting maintenance, repair is very convenient. If the drive is broken, change the drive; if a LED light source module is damaged, replace the damage module; if the LED light source life expires or product replacement, as long as the replacement of the components can be, without the need to replace the entire lamp. On the one hand, it saves costs and on the other hand it is easy to operate. The entire maintenance process is as convenient as the lamps with traditional light sources. LED street lamps designed according to this idea have been lit on Fudan University campus.

At present, most LED street lamps use integral lamps. The advantages of traditional light source lamps in terms of maintenance, use costs, etc., make us think about the development direction of LED street lamps. China's current LED street lights There are many manufacturers and different forms of lamps and lanterns, which also poses challenges for the industry's specifications. The light source module is expected to solve these problems and become the development direction of LED street lamps.
