Abstract
The present invention relates to a light source module comprising a light source, which light source module comprises cooling means for cooling the light source base, which light source module further comprises a dechroic reflector, where at least one heat sink surrounds the dechroic reflector. The object of the present invention is to reduce the temperature at the lamp base to increase the lifetime of a lamp. This can be achieved by a light source module that comprises at least a first heat sink, which first heat sink comprises a number of dishes, which dishes are formed to achieve air gabs there between, which dishes comprises at least one opening for the dechroic reflector, which dishes are placed radially around the dechroic reflector, which air gabs between the dishes are directed mostly perpendicularly to a centre axis of the light source module. Hereby, it is achieved that most of the infrared light, which is radiated in the direction of the dechroic reflector is absorbed in the dishes of the heat sink, and because the direction of the dishes is perpendicular to the main axis of the lamp module, the dishes conduct the heat radially towards the outer surface of the dishes.
