Abstract

The invention relates to a lighting fixture, comprising a substantially planar carrier which on a first side is provided with at least one light source and on a second side opposite the first side is provided with a cooling body for dissipating heat generated by the light source. The cooling body comprises cooling elements which extend from the planar carrier in a direction away from the carrier. Further, the cooling body comprises a flow path for a convection flow, which extends from the periphery of the carrier to a central part of the cooling body which is free from cooling elements.
