[0002] In modern lighting applications, light-emitting diode (LED) light sources have gradually replaced traditional light sources due to their energy-saving, high-efficiency, and good stability. The time cannot meet the application requirements, so it is necessary to distribute light to the LED light source. At present, the industry uses optical devices such as reflective cups or lenses to control the light emitted by the LED, so as to meet the lighting requirements. This light distribution method requires optical devices. It takes a lot of space, and requires a lot of investment in the cost of optical devices and assembly costs, which is not conducive to the development of miniaturization and ultra-thinning of lamps and the reduction of costs
