    • The principle of LED lamp

      LED (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device that converts electricity directly into light. The heart of the LED is a semiconductor chip, one end of which is attached to a bracket, 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.
