What to Do When LED Bulbs Keep Burning Out?
1 Answers
LED bulbs frequently burning out may be due to an abnormal low beam relay, which can be resolved by replacement. Below is relevant information about LED bulbs: Basic Definition: LED bulb is the English abbreviation for light-emitting diode, abbreviated as LED, which is a common term. Luminescence Principle: The terminal voltage of the PN junction forms a certain potential barrier. When a forward bias voltage is applied, the potential barrier decreases, and the majority carriers in the P and N regions diffuse toward each other. Since electron mobility is much greater than hole mobility, a large number of electrons diffuse into the P region, constituting minority carrier injection into the P region. These electrons recombine with holes in the valence band, and the energy obtained during recombination is released in the form of light energy. This is the luminescence principle of the PN junction.
