LED tube light is application of a new type of LED lighting light source on the basis of traditional tube light of the development of improved products, compared with traditional tube light has the following advantages: energy saving, low carbon, long life, good color rendering and fast response.LED tube light, a design more beautiful light, installation to keep building decoration of the overall unity and perfect, does not destroy the set of lamps and lanterns, light hidden inside the building decoration, light source is not exposed, no glare, the visual effect of soft and uniform.
P-n junction terminal voltage constitute a certain potential barrier, when the positive bias voltage drop time base, P and N the majority carrier diffusion to the other party.Due to the electron mobility is much bigger than hole mobility, so there will be a large number of electronic spreading P area, constitute of P area of minority carrier injection.These electrons and valence with hole composite, composite when the energy in the form of light energy to release out.This is the principle of PN junction glow.
