SMD LED means surface mount light emitting diode, SMD SMD chip helps to increase production efficiency as well as different facility applications. It is a solid state semiconductor device that converts electricity directly into light. It has a voltage of 1.9-3.2V, with the lowest voltage for red and yellow light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a holder, one end is negative, and the other end is connected to the positive end of the power supply, so that the whole wafer is encapsulated by epoxy resin. Semiconductor wafer consists of two parts, one is a P-type semiconductor, in which holes dominate, the other end is an N-type semiconductor, on this side is mainly electrons. However, when these two semiconductors are connected, a P-N junction is formed between them. When the current through the wire acting on this wafer, the electrons will be pushed to the P region, in the P region, the electrons and holes compound, and then will be issued in the form of photons of energy, which is the principle of LED light. And the wavelength of light, which is the color of light, is determined by the formation of the P-N junction material.
1. Flexible, can be curled like wire
2. Can cut and extend the connection, the shortest can do 1 light a cut.
3. Lamp beads and circuits are completely wrapped with flexible plastic, insulated, waterproof and safe to use.
4. High brightness, long service life.
5. Mature industry chain, complete automation equipment, high capacity
6. Easy to install, height can be customized. Circuit board is lighter and thinner, suitable for various installation scenarios.
7. Easy to make graphics, text and other shapes.
