Lamp for illumination of a surface of a building

摘要

The light (10) has a light source arranged at an interior (19) of a cup-shaped curved reflector (21), where the light source is selected from a group consisting of a HIT-TC-CE-lamp and halogen-lower volt-incandescent lamp such as QT 12-aX or LED. A set of cylindrical segments (14a-14n) is arranged at a reflector inner side (30). The inner side exhibits a surface that is curved to an inner area. The segments are arranged between a vertex (S) and a free edge area (R) of the reflector, and a cylinder axis is aligned under a pointed angle along a longitudinal center axis of the reflector.
