Abstract: A luminaire reflector composed of a pot-like hollow, rotationally symmetrical, frustoconical reflector body having a peripheral wall that is circularly curved in a peripheral direction and increases in diameter from a rear side up to a front light exit opening is provided. The reflector body has an outwardly bent over, annular peripheral edge web that surrounds the light exit opening and is bounded by two circles of different radii. The peripheral wall of the reflector body is longitudinally divided into two to four shell-like wall parts correspondingly curved in the shape of a circular arc in a peripheral direction, or the peripheral may be formed from one piece. Each wall part, or the unitary peripheral wall, together with a part of the annular peripheral edge web, is formed from a pre-coated sheet metal material that is strongly optically reflecting at least on the inside.
