Background

The LED lamp bead is a semiconductor diode and can convert electric energy into light energy. The light emitting diode is composed of a PN junction as common diodes, and also has unidirectional conductivity. When a forward voltage is applied to the light emitting diode, holes injected from the P region to the N region and electrons injected from the N region to the P region recombine with the electrons in the N region and the holes in the P region within a few micrometers near the PN junction, respectively, and spontaneous emission fluorescence is generated. The energy states of electrons and holes are different in different semiconductor materials. The more energy is released, the shorter the wavelength of light emitted, the more energy is released when electrons and holes recombine. Diodes emitting red, green or yellow light are commonly used. The reverse breakdown voltage of the light emitting diode is greater than 5 volts. Its forward current-voltage characteristic is very steep and in use a current limiting resistor must be connected in series to control the current through the diode.
