Abstract:
1. Reflector luminaire with a light-emitting means and a reflector, which reflects light from the light-emitting means which is incident on said reflector in a predetermined emission direction and has a rim which points towards the emission direction, said reflector comprising: a plurality of differently designed segments each consisting of a single curved facet, said segments being aligned radially and symmetrically with respect to a mid-axis of said luminaire such that all segments run substantially radially from the rim in the direction of the mid-axis and which run with a continuous curvature in the region used for the reflection, said segments being calculated individually with respect to the light-emitting means in terms of their shape, namely their width, length and curvature for defined illumination of a predetermined area; and a plurality of transition sections joining adjacent segments, wherein the predetermined total reflecting surface of said segments comprises more than seventy-five percent of the total surface area of the reflector.
