Abstract: The present invention relates to an illumination device comprising a number of light sources and a number light collecting means, where the light collecting means collect light generated by the first light sources and convert the light into a source light beam propagating primarily along a primary optical axis. The light source module comprises a cooling module comprising a number of interconnected plane mounting surfaces angled in relation to each other and where the light sources is arranged on said plane mounting surfaces. The cooling module comprises a first side comprising the mounting surfaces and a second side comprising a number of cooling fins defining a number of radial air channels.
