Abstract (en)

[origin: WO2015051810A1] A light fixture, in particular for use in areas in which there is a risk of explosions, has at least a lighting means, a cooling device for the lighting means and a light fixture housing with a light exit opening, wherein at least the lighting means and the cooling device are arranged in the light fixture housing. In order to improve heat transfer from the lighting means, in particular from the cooling device, to the light fixture housing in a simple and reliable manner without the additional use of a thermally conductive paste or the like, wherein corresponding manufacturing tolerances, which can have a negative influence on good thermal contact, no longer have to be taken into account, the cooling device has, for heat transfer to the light fixture housing, a cooling element of variable length or is in the form of a cooling element of variable length.
