LED street lights are mainly used for road lighting such as main roads, secondary roads, branch roads, factories, schools, gardens, urban squares, courtyards, etc.
The increase 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-fired, bat-wing and concentrating. In the field of road lighting, based on design experience, Lambertian and bat wing are more suitable. Through secondary optical design, the illumination range and luminosity curve of LED can meet the needs of road lighting.
The most common form of LED used in road lighting is mainly in the lighting. A matrix LED is installed on an almost flat mounting surface (also a reflective surface). This design method is impossible to get a good lighting. Light distribution.
