Abstract: The invention relates to a cooling device for a headlight of a motor vehicle, in particular for a laser headlight. The cooling device comprises a cooling body for thermal contacting a light source of the headlight and one or more passive air guides. A respective air guide comprises an inlet conduit and an outlet conduit so that, while the motor vehicle is moving, outside air from outside the headlight is fed to the cooling body via the inlet conduit and the outside air is discharged again via the outlet conduit. The outside air enters the inlet conduit via an inlet opening and exits the outlet conduit via an outlet opening, both openings positioned remotely from the cooling body. The cooling device may be positioned in the motor vehicle such that, while the motor vehicle is moving, the air pressure at the inlet opening is higher than the air pressure at the outlet opening.
