Abstract

LIGHT FIXTURE A light fixture (10) is described and illustrated. The special feature consists in the fact that faceted segments (14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h, 14i, 14j, 14k, 14l, 14m, 14n) having a cylindrical surface (OF) are situated on the inner surface (30) of a dish-shaped, curved reflector (21). The cylinder axes (m, m1, m2, m3, m4) of the segments are oriented in such a way that, according to the differing spacing of the segment to a vertex region (S) of the reflector (21), the orientation of the segment with respect to a tangent (T1, T2, T3, T4), which may be applied to the exterior (38) of the reflector (21) in a connecting region (15b, 15f, 15i, 15n) of the segment on the reflector, varies.
