Multi LED chips are packaged together as one light module. When it lights up, it looks like a lighting panel.How COB 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
