Lighting device i.e. LED lighting device, for e.g. interior environment, has base comprising heat pipe that extends from hot end to cold end, where cold end is provided with heat distribution elements and hot end supports light source

摘要

The device (1) has a base (2), a light source (3) i.e. LED light source, and a heat distribution system (4) that comprises multiple heat distribution elements (5) protruding from the base. The base longitudinally extends along an axis (A) between a hot end (11) and a cold end (12). The hot end supports the source. The cold end is provided with the distribution elements. The base has a heat pipe extending from the hot end to the cold end. The source and the elements protrude transverse to the axis. The base is made from flat sheet. The base is made of metallic material such as aluminum.
