When the forward voltage is applied to the light-emitting diode, the holes injected from the P area to the N area and the electrons injected from the N area to the P area are respectively in the vicinity of the PN junction with the electrons in the N area and the P area. The holes recombine to produ......

A light-emitting diode (LED) is a light-emitting display device made of semiconductor materials such as gallium phosphide (GaP) that can directly convert electrical energy into light energy. When there is a certain current passing through it, it will emit light.

Light-emitting diodes are a kind of semiconductor components. At the beginning, it was mostly used as indicator light, display light-emitting diode board, etc

If the lamp strip in the LED lamp is aged or damaged, you can only replace the lamp strip in the lamp tube without replacing the lamp shell.

LED (light emitting diode) is a solid-state semiconductor device that can convert electric energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor wafer.
