Abstract

The invention relates to a luminaire having a light source (2) which has at least one light emitting semiconductor, and having a, as seen from the light source (2), concave reflector (1), the light source (2) being arranged in substance in the longitudinal axis of the reflector (1). In accordance with the invention, the light source (2) is of a plurality of luminous diodes (4) arranged on a carrier surface (3) and controllable, the ratio between the carrier surface (3) and the opening of the reflector (1) being between 1:3 and 1:20.
