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
