Abstract: A method for generating an air stream for cooling a light source, and a light source module for a light fixture with a blower for cooling the light source and the light source base. To achieve highly effective cooling of a lamp in a light fixture or a projector at least one forced air stream is generated by a blower system which blower system can be placed at a distance from the light source module and can be connected from the blower through a tube to a duct which directs an air stream towards the light source. By using a tube for the connection between the blowing unit and the actual place where air stream is to be used for cooling, it is possible to operate the blower in a place where the suction inlet for air into the blowing unit is a relatively cool place.
