[0014] Figure 1 is a schematic diagram of the overall structure of the LED street light optical system, including a main reflector 1, an auxiliary reflector 2, an LED lamp 3 and several connecting pieces. The main reflector 1 is composed of m basic units, the axes of the main reflecting surfaces of each basic unit are parallel to each other, forming m rows, and there are n holes at the bottom of each basic unit of the main reflector 1 for placing n LEDs, Among them, n is the number of LEDs in each row, and there are 2 auxiliary reflectors 2, which are respectively located on both sides of the main reflector and installed in the "V"-shaped grooves on the top of both sides of the main reflector. 1. The auxiliary reflector 2 and the LED lamp are connected and fixed together. m is the number of rows of LEDs, m≥1; n is the number of LEDs in each row, n>1. The light emitting surfaces of all LED chips are located in the same plane.
[0015] The basic unit of each primary reflector ...
