Just What is COBs LED

This is a COBs LED used in car headlight revealed as above. COB offers high light source result, each chip could get to 2000-3000 lumen. COB light-spot is a complete surface light but not a direct light source. Even it makes use of ceramics with good thermal conductivity or superconducting aluminum as the substrate, surrounding the beautiful area right into strips, due to the constraints of the package, COB LEDs still can not accomplish the application objectives on vehicle lights for small size, high existing as well as high reliability.

The automobile led front lights made use of COBs LED, is easy to triggered scatted light when the emitted-light go beyond the main light giving off area of 1-1.2 mm, since its light releasing surface is larger too much than halogen filament. That can not increase reliable illumination driving on road; yet will certainly trigger amazing to oncoming web traffic. Although the cost of COBs LED headlight is cheap, the beam is poor, it is not reliable working in high present for long time.
