The LED patch lamp is made of FPC circuit board, LED lamp, and silicone sleeve. Waterproof performance, convenient use of low-voltage DC power supply, diverse luminous colors and bright colors. SMD diodes, also known as crystal diodes, are electronic devices that conduct current in one direction. There is a PN junction and two lead terminals inside the semiconductor diode. This kind of electronic device has unidirectional current conductivity according to the direction of the applied voltage. Generally speaking, the chip crystal diode is a combination of P-type semiconductor and N-type semiconductor Sintered PN junction interface. Space charge layers are formed on both sides of the interface to form a self-built electric field. When the applied voltage is equal to zero, the diffusion current and the drift current drawn by the self-built electric field are equal and in an electrical equilibrium state due to the difference in the carrier concentration on both sides of the PN junction.

The SMD LED Diode is widely used in various home appliances, digital products, LED backlights, LED displays, computers,
communications, automotive electronics, electronic toys, electronic and electrical indicators, lighting, urban lighting projects, etc.
