What is COBs LED

This is a COBs LED used in lorry front lights revealed as above. COB offers high light source output, each chip can reach 2000-3000 lumen. COB light-spot is a complete surface area source of light but not a straight light source. Also it uses porcelains with excellent thermal conductivity or superconducting aluminum as the substratum, bordering the glowing location into strips, because of the limitations of the bundle, COB LEDs still could not achieve the application objectives on auto lights for tiny dimension, high current and high reliability.
The car led headlight made use of COBs LED, is easy to caused scatted light when the emitted-light exceed the central light producing location of 1-1.2 mm, since its light emitting surface area is larger way too much than halogen filament. That can not raise reliable lighting driving on road; however will trigger stunning to oncoming traffic. Although the cost of COBs LED headlight is cheap, the light beam is poor, it is not trustworthy working in high present for long time.
