A cooling system for a projector for dissipating the heat output by a light source and/or optical components or electric and electronic components through which current flows in a projector housing with a lamp housing and a base tray is provided. The cooling system comprising a first cooling device in which a first convection flow is guided through the interior space of the base tray and the lamp housing and around which a second convection flow circulates which circulates around the lamp housing at least partially in the circumferential direction, and a second cooling device for a cooling air flow which is directed substantially perpendicularly to the second convection flow and runs parallel to the optical axis of the projector.
