AI Technical Summary
The lighting direction of existing LED street lights is unidirectional, resulting in limited lighting area, and brightness and power consumption need to be increased to ensure lighting effect.
A double-sided luminous photoelectric semiconductor module is designed. By setting a reflector and a thermal conductor in the street lamp, the light of the LED lamp beads is reflected in both directions under the action of the reflector, increasing the lighting area.
