Abstract: A light fixture (14) is shown and described for illuminating a building surface (19) and having a fixture housing (26) holding a bowl-shaped reflector (11) with a generally rotation-symmetrical (11) outer surface centered on a longitudinal center axis (M) and an inner surface (16) provided with a plurality of segments (15) for producing a rotationally asymmetrical illuminated zone. The novelty is, inter alia, that the fixture housing has a rotary bearing (29) for the reflector so as to enable rotation of the reflector about its central longitudinal axis, and in that a device (30) is provided on the fixture housing for rotationally arresting the reflector, the device fixing the reflector relative to the fixture housing in any of a plurality of angularly offset positions.

Abstract: Described and illustrated are, among other things, a prismatic lens (10) for a light fixture (25), comprising a light-entry side (11) and a light-exit side (12), and comprising a plurality of prisms (16, 16a, 16b, 16c, 16d, 16e, 16f, 16g, 17, 17a, 17b, 17c, 17d, 17e, 17f, 17g) arrayed in a structured manner and used for directing light along a preferred direction (V). The invention is characterized in that at least partial regions (24, PF2) of the light-exit side (12) have a light-diffusing design.

Abstract: A light fixture (10) is described and shown. Its uniqueness is comprised inter alia in that facet-like undercut segments (14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h, 14i, 14j, 14k, 14l, 14m, 14n) are arranged on the interior (30) of a cup-shaped curved reflector (21).

Abstract: 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.

Abstract: A light fixture is shown and described is for illuminating building surfaces or portions thereof, comprising a generally cup-shaped arcuate reflector (10) having an interior (21) provided with a lamp emitting light at least partially reflected or dispersed by an inner surface (27) of the reflector to the building surface or portion to be illuminated, the inner surface of the reflector being subdivided into a plurality of structured segments (15a, 15b, 15c, 15d, 32, 38). The novelty is that the segments each have a surface (31a, 31b, 31c, 36, 37, 40) that is curved toward the interior.
