CoB LED is a single device with many LED chips mounted on a thermally efficient substrate, or board. Each chip is a bare die – that is, the chip does not have its own leadframe, phosphor coating or lens. This means that the chips can be mounted extremely closely together on the substrate.
COB LEDs are brighter, consume less power, and output a higher quality beam of light compared to older LED technologies found in most other trade show lighting.
