Description

technical field [0001] The invention belongs to the technical field of lighting, and more specifically, the invention relates to a light engine structure with the same substrate for optical devices. Background technique [0002] LED is a new type of solid-state cold light source. It has the advantages of simple structure, light weight, small size, low energy consumption, fast response, good shock resistance and convenient use, so it is favored by people. Under the same illuminance, the power consumption and lifespan of LED lamps have obvious advantages over incandescent lamps and fluorescent lamps. Moreover, LEDs can be used not only as indicator lights, display light sources and signal light sources, but also for general lighting. Therefore, people have formed a consensus that LED is the fourth-generation light source after incandescent lamps, fluorescent lamps and HID lamps, and is recognized as the most promising electric light source in the 21st century. [0003] The m...
