COB (Chip-on-Board)
The "naked" semi-conductors are applied to the substrate, a process that enables much denser LED arrays in comparison to SMD technology. The great advantage of COB modules lies in the highly homogeneous light they emit. That means a consistent light beam is emitted, without any visible individual light points. The addition of a ceramic substrate then creates optimal conditions for cooling, which contributes to higher efficiency and a longer service life.
