Abstract

There is provided a lighting device (100) comprising a printed circuit board, PCB, a light source (101) for emitting light mounted on the PCB, and a heat release member (105) for dissipating heat generated by the light source. The light source is thermally connected to at least one electrically and thermally conductive portion of the PCB by at least one contact, and the PCB is arranged such that an upper surface (108) of the PCB is arranged in thermal connection with an upper inner surface (116) of a cavity (115) arranged in the heat release member, while the light source is arranged in an aperture (118) of that cavity. Heat generated by the light source is transferred along a heat transfer path extending from the light source via the at least one contact and at least one thermally conductive portion to the heat release member via the interface formed by the upper surface of the PCB and the heat releasing member. Further, a corresponding light emitting system is provided.
