LED street lights are mainly used for road lighting, trunk roads, secondary trunk roads, branch roads, factories, schools, gardens, city squares, courtyards, etc.
The improvement of output power and luminous flux also needs to be further improved from the basic level of high-power white LED epitaxial technology and chip technology. In terms of secondary optical design, the radiation forms of LEDs are Lambertian, side-fire, batwing and concentrating. In the field of road lighting, according to the design experience, Lambertian and batwing are more suitable. Through the secondary optical design, the illumination range and luminosity curve of LED meet the requirements of road lighting.
The most common form of LED used in road luminaires is mainly in the luminaire. On an almost flat mounting surface (also a reflective surface), a matrix LED is mounted. This design method is impossible to get a good luminaire. Light distribution.
