Introduction to DC COB LED

DC COB (Chip-on-Board) LED is a type of light - emitting diode technology. In a DC COB LED, multiple LED chips are directly mounted on a substrate, which allows for a high - density arrangement of chips. This design results in a more concentrated and uniform light source compared to traditional single - chip LEDs. DC COB LEDs are known for their high luminous efficacy, good color rendering index (CRI), and long lifespan. They are widely used in various lighting applications such as commercial lighting, industrial lighting, and architectural lighting due to their excellent performance and energy - saving characteristics.
