Heat dissipation for lamp headsets

A modification to plastic mining lamp headsets to improve heat dissipation consists of stripping a lamp headset (a) to a bare shell, rebating the rear of the lamp where the original helmet bracket (e) fits, and drilling out and tapping the existing charging keyway aperture at the rear of the lamp. A threaded plug (b) of heat conducting material is screwed into the aperture, and its rear machined flush to accept a finned external heat sink (c) that is retained in position by the helmet bracket (e). A heat sink plate (d) is attached to the end of the plug (b) and is used to mount LEDs. The heat generated by the LEDs is conducted to the heat sink (c) and dissipated. The modification provides a lamp capable of handling powerful LEDs which is suitable for recreational caving, cycling, exploring and potholing.
