This is a COBs LED used in car headlight revealed as above. COB provides high source of light result, each chip could get to 2000-3000 lumen. COB light-spot is a complete surface light source however not a straight light source.

Even it utilizes porcelains with good thermal conductivity or superconducting light weight aluminum as the substratum, bordering the radiant location right into strips, as a result of the limitations of the plan, COB LEDs still can not attain the application goals on automobile lighting for little size, high present and high reliability.

The auto led front lights used COBs LED, is simple to caused scatted light when the emitted-light surpass the central light releasing location of 1-1.2 mm, due to the fact that its light producing surface area is bigger way too much compared to halogen filament. That could not enhance effective lighting driving on road; but will certainly create stunning to oncoming traffic. Although the expense of COBs LED front lights is cheap, the beam is inadequate, it is not reputable working in high existing for long period of time.
