Description

TECHNICAL FIELD

[0002] LED lamp pearl is the English abbreviation of light-emitting diode, which is a popular name, and the principle of LED lamp pearl is that the terminal voltage of PN junction forms a certain potential barrier. When a forward bias voltage is applied, the potential barrier decreases, and the majority carriers of the P region and the N region diffuse to each other. Because the electron mobility is much higher than the hole mobility, a large number of electrons diffuse to the P region, forming injection of the P region minority carriers. These electrons and holes on the valence band recombine, and the energy released in the process is released in the form of light energy. LED lamp pearl consumes less power when working, has high energy efficiency, and can emit bright light, meet various lighting needs, has strong vibration resistance, and is suitable for various complex environments.
