COB & SMD LED Heat Sinks

Wakefield Thermal COB and SMD LED Heat Sinks for active and passive cooling are compact with a large cooling surface area. Concentrated heat requires sufficient thermal contact areas to quickly help the heat sink to dissipate heat through passive cooling. If the central conductive column of the heat sink is too large, the heat cannot be quickly transferred to the heat sink. A large amount of heat will be attached to the inside of the lamp, resulting in a large increase in temperature. The heat on the COB source cannot be completely transmitted, and the service life will be rapidly reduced. This can potentially pose a safety hazard. Wakefield Thermal COB and SMD LED Heat Sinks allow for active and passive cooling over the whole surface.
