1. COB ( Chips on Board ) is a new technology of LED packaging of LED light engine.
2. In COB lighting, single LED chips are placed directly on a circuit board ( or substrate ) which has thermal properties to disperse heat.
3. Heat dissipation as a very important aspect of LED lighting, it can have a major impact on the life expectancy of the luminary.
4. COB lighting can have a higher LED chip density and achieve higher light level while maintaining or improving life expectancy.
5. COB led lights are also a more efficient form of LED lighting for general or automotive lighting applications.
