LED tube light, luminous principle and characteristics

in LED spotlights is a kind of embedded in the ceiling light beam type of lighting lamps and lanterns. LED tube light is directional lighting lamps and lanterns, can only by the light of the opposite, the beam Angle belongs to the condenser, the light is relatively concentrated, comparative and intense light and shade. More prominent as objects, lumens degrees higher, more foil a quiet atmosphere.

the LED spotlights is mainly by way of diodes lighting, life depends mainly on solid LED light source and drives the cooling section, 2012 led downlights life has reached more than 80000 hours, with the development of LED technology research and widely used, has reached a relatively ideal drive and thermal state, compared with the ordinary halogen tube light, commercially available high quality led downlights life reached more than 80000 hours.

luminescence principle: PN junction terminal voltage of a certain potential barrier, when to add 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.

the LED downlight features: keep building decoration of the overall unity and perfect, does not destroy the set of lamps and lanterns, light hidden inside building decoration, no leakage, no glare, the visual effect of soft and uniform.
