Abstract
The invention relates to a lighting fixture () which comprises at least one lighting fixture housing () and a cover () and which is constructed particularly as a safety and/or emergency exit light and/or as an explosion-proof light. A light is held by a clamp connection () at the lighting fixture housing, and at least one auxiliary electrical device () into the light is disposed at the lighting fixture housing. The lighting fixture can be expanded with a lower expense for the installation and with all explosion-protection measures observed, by virtue of the lighting fixture housing () having conductor rails () for supplying electricity to the light and to the auxiliary electrical device, where the auxiliary electrical device is constructed as a plug-in module which can be plugged onto the conductor rails.
