Street lights are widely used in various places where lighting is required. Street lights involve lighting technology and are suitable for street lights. The purpose is to design a high-efficiency energy-saving street lamp with long life, low power consumption and high brightness. LED, light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a bracket, and one end is a negative electrode , the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.

Existing street lamps generally adopt a closed structure to prevent the damage of rainwater.
