What is COBs LED
This is a COBs LED used in automobile headlight revealed as above. COB supplies high light outcome, each chip can get to 2000-3000 lumen. COB light-spot is a full surface area light however not a straight light source.
Also it makes use of porcelains with excellent thermal conductivity or superconducting light weight aluminum as the substrate, surrounding the radiant area right into strips, because of the restrictions of the package, COB LEDs still can not attain the application goals on automobile illumination for little size, high current and high dependability.
The car led front lights utilized COBs LED, is very easy to caused scatted light when the emitted-light exceed the main light giving off location of 1-1.2 mm, since its light giving off surface area is bigger excessive compared to halogen filament.
That can not enhance efficient illumination driving on road; however will certainly cause spectacular to oncoming web traffic. Although the cost of COBs LED headlight economicals, the light beam is bad, it is not dependable working in high current for long period of time.
