Abstract
A thermally conductive heatsink is for cooling a plurality of light emitters within a lamp, luminaire, lighting device or ancillary apparatus thereof, the heatsink having one or more holes, recesses, compartments, chambers or internal cavities for locating one or more cells, batteries or other charge storage devices able to provide power to electronic control circuitry and or light source(s). The internal cavities may additionally provide space to fully or partially locate electronic circuitry or electrical components. Conjointly to thermal operation, the heatsink may act as a chassis or holder for one or more components of the lamp, luminaire or lighting device. The cooling elements can be of any size, design or material, and the heatsink can have one or more parts each of any shape, design, construction or material.
