Wakefield- Vette's COB & SMD LED heat sinks are compact size with a large amount of surface area. This allows the  concentrated heat requiring sufficient thermal contact area to quickly help the heat sink core source to dissipate heat through passive cooling. And if the central conductive column of the heat sink is too large, the heat cannot be quickly transferred to the heat sink and a large amount of heat will be attached to the inside of the lamp, resulting in a large increase in temperature. Therefore, the heat on the COB source cannot be completely transmitted, and its service life will be rapidly reduced, potentially posing a potential safety hazard. Therefore these style of heat sinks allow for passive cooling.
