SOLID STATE LIGHTING MODULE WITH IMPROVED HEAT SPREADER

摘要

A solid state lighting module (102) for attachment to a socket (103) through rotation of the solid state lighting module around an axis of rotation (111). The solid state lighting module (102) comprises at least one solid state light-source (112); a heat spreading member (104) having two surfaces arranged opposite each other and in thermal connection with each other, the first surface (114) being in thermal connection with the solid state light-source (112); and fastening means (109) arranged to co-operate with fastening means (113) comprised in the socket (103) to bring the second surface (115) of the heat spreading member (104) in thermal connection with a heat sink (110) comprised in the socket (103). The second surface (115) of the heat spreading member (104) has a surface topography with at least one peak (119) and at least one valley (120) arranged concentrically in relation to the axis of rotation (111).
