  • Covering and luminaire having such a covering
    Patent number: 9400098
    Abstract: A cover, in particular for an explosion-proof luminaire at least comprises a mounting frame, which is detachably fastened to the luminaire, and a transparent luminaire cover held at least along a circumferential edge by the mounting frame. In order to improve a cover of this nature to the effect that it is protected in a cost-effective manner and without substantial constructive effort from the occurrence of microcracks due to the effects of shocks and impacts on the luminaire cover, a transparent protective cover is placed in front of the luminaire cover for a flameproof and impact-resistant embodiment of the cover. The invention also relates to an explosion-proof luminaire with a cover of this nature.
