The rise of the domestic LED lighting market begins with the field of
LED street lights . From “Ten Cities and Ten Thousand Miles” to “Fifty Cities Millions”, LED outdoor lighting has been rapidly developed by the encouragement of policies. In order to better adapt to the development of the market, LED companies have strengthened the research and development of technology. From single imitation lumens to today's light engine modules, the rapid advancement of technology has greatly promoted the development of LED street lamps.
The so-called modularization means that a composite module such as a light source, a heat dissipating component, and a driving power source is mass-produced, and a standardized LED lighting product is manufactured according to fixed parameters and a mold.
At present, there are not a few companies that do modularization. Xu Min, technical director of Shanxi Guangyu, introduced at the 2014 High-tech LED Annual Meeting that most of the light source module solutions with direct heat dissipation are directly made of lenses made of polymer materials. When exposed to sunlight, the module is sealed with silicone. At the same time, the wires connected by the modules are also directly exposed to sunlight. The long-term exposure of these materials to ultraviolet rays will have a significant impact on the performance of these materials, such as lens yellowing, deterioration of the silica gel, resulting in decreased sealing performance, and wire aging. In Xu Min's view, for outdoor street lights, cost and price are not the most important, reliability is.
A standardized and good light engine can solve many difficult problems in high-power LED lighting, such as heat dissipation, waterproof, serialization, maintenance, and versatility. Chen Kai, general manager of Maple Yongming, believes that the module should be IP68. IP68 is to close the whole thing, just like the traditional light bulb, including boiling in boiling water. "This is actually done, and now it has already been mass-produced." Chen Kai said.
Once the reliability is guaranteed, you should pay more attention to the uniqueness of the module for LED street lights and the superior performance of traditional street lighting.
"A few years ago, everyone wanted to treat streetlights as a kind of scenery. Now, I don't know how everyone thinks about the city's appearance of such streetlights now," Xu Min said.
Today's street lights are not very characteristic. I believe that few people will have an impression of the street lights on a certain road, because they look similar, one pole plus a flat plate and a lampshade. LED as a "high-precision" in essence of electronic products, it is entirely possible to make a difference, so that each road has the characteristics of each road, so that people can shine.
In fact, from the modular design, whether it is the modularization of the light source or the modularization of the light engine, it provides a broad design space for the design. In the future, different modules can be selected according to different application requirements. From this point of view, LED street lighting companies, including outdoor high-power module manufacturers still have a lot of articles to do.
You can't talk about products from the market, and you can't talk about the market from the product. Since we are already in the era of LED lighting, what we have to do is to study how to maximize the advantages of LED and better serve the people's lives.
