Abstract

The device has a base reflector with a first reflector axis for holding a light source and an ancillary reflector with a second axis for mounting in a wall or ceiling element. The reflector axes enclose an obtuse angle. The reflector opening contours at the joint are unequal. A flange arrangement on one butting opening edge extends inwards or outwards and is dimensioned to cover the region of one opening contour protruding beyond the other. The device has a base reflector (2) with a first reflector axis for holding a light source and an ancillary reflector (6) with a second axis for mounting in a wall or ceiling element. The reflector axes enclose an obtuse angle and the opening contours of the reflectors at the joint are unequal. A flange arrangement (3) on one of the butting opening edges extends inwards or outwards and is dimensioned so that the region of the opening contour protruding beyond the other contour is covered.
