LIGHT SOURCE MODULE

摘要

The present invention relates to a light source module (2) comprising a light source (4), which light source module (2) comprises cooling means (8) for cooling the light source base (6), which light source module (2) further comprises a dechroic reflector (10), where at least one heat sink (12) surrounds the dechroic reflector. The object of the present invention is to reduce the temperature at the lamp base (6) to increase the lifetime of a lamp. This can be achieved by a light source module (2) that comprises at least a first heat sink (12), which first heat sink (12) comprises a number of dishes (14), which dishes are formed to achieve air gaps (16) therebetween, which dishes (14) comprises at least one opening for the dechroic reflector (10), which dishes (14) are placed radially around the dechroic reflector (10), which air gaps (16) between the dishes (14) are directed mostly perpendicularly to a centre axis (18) of the light source module (2). Hereby, it is achieved that most of the infrared light, which is radiated in the direction of the dechroic reflector (10) is absorbed in the dishes (14) of the heat sink (12), and because the direction of the dishes (14) is perpendicular to the main axis (18) of the lamp module (2), the dishes (14) conduct the heat radially towards the outer surface of the dishes (14).
