Just What is COBs LED
This is a COBs LED made use of in car headlight showed as above. COB supplies high light source output, each chip could reach 2000-3000 lumen. COB light-spot is a complete surface light yet not a straight source of light. Even it uses ceramics with great thermal conductivity or superconducting aluminum as the substratum, surrounding the beautiful area into strips, due to the limitations of the bundle, COB LEDs still can not attain the application goals on auto lighting for little dimension, high current and also high reliability.
The vehicle led front lights utilized COBs LED, is easy to triggered scatted light when the emitted-light surpass the main light producing location of 1-1.2 mm, because its light giving off surface is bigger too much than halogen filament. That can not enhance efficient lighting driving on roadway; but will certainly create stunning to approaching website traffic. Although the price of COBs LED front lights is cheap, the light beam is bad, it is not trusted working in high current for long time.
