How COB (chip on board) LED light source works?
In COB lighting, single LED chips are placed directly on a circuit board (or substrate) which has thermal properties to disperse heat.
Heat dissipation is a very important aspect of LED lighting since it can have a major impact on the life expectancy of the luminary.
Therefore, COB lighting can have a higher LED chip density and achieve higher light level while maintaining or improving life expectancy.

Advantage of COB:
COB lights are a more efficient form of LED lighting for general or automotive lighting applications because:
- light has a more uniform appearance
- better life expectancy
- achieve higher light level over a large area
- COB is more stable and reliable than standard LED package
