Background

L ED is English (light emitting diode), L ED lamp bead is the abbreviation L ED for light emitting diode, which is a popular name.

The working principle is as follows: the terminal voltage of the PN junction forms a certain potential barrier, when a forward bias voltage is applied, the potential barrier is lowered, and most carriers in the P region and the N region diffuse to each other. Since electron mobility is much greater than hole mobility, a large number of electrons will diffuse into the P region, constituting an injection of minority carriers into the P region. These electrons recombine with holes in the valence band and the energy obtained upon recombination is released as light energy. This is the principle of PN junction luminescence.
