Abstract
The invention relates to a lighting device comprising a light source () which is mounted on a heat sink () having an outer contour (). Furthermore, it comprises a cooling device () for dynamically cooling the light source via cooling of the heat sink by means of a fluid flowing alongside the contour of the heat sink, the cooling device having one or a plurality of cooling openings (). The cooling device is a vibrating membrane cooling system for generating a sequence of fluid pulses (). The cooling openings are arranged alongside the heat sink. The light source comprises optical means () for collimating and directing light originating from the light source during operation, while the contour of the heat sink has a shape similar to that of the optical means.
