Abstract
A surface luminaire with a luminous chamber in the form of a hollow fiberoptic conductor is provided. The luminous chamber comprising a peripheral frame, an emission opening and a base plate which is populated at least partially with light-emitting diodes and on which sloping faces are arranged. The sloping faces bridge the edge region of the base plate and a region of the peripheral frame which adjoins the base plate and form a cavity between the lower region of the peripheral frame, the edge region of the base plate and the sloping faces, in which cavity control electronics, which drive the light-emitting diodes, are arranged.
