LUMINAIRE

摘要

The luminaire comprises a concave reflector (1) with an optical center (2) on an optical main axis (3), in an optical main plane (4). A screen (6) extends along the main axis (3) up to a light emission window (5). A panel (7) extends at a first side of the main plane (4) from the screen (6) up to the light emission window (5). The reflector (1) includes a first, faceted reflector portion (10) at the first side of the main plane (4), which extends towards the main plane (4), and which may be parabolically curved, the optical center (2) being its focus and the main axis (3) being its axis. A second, faceted reflector portion (20) is present at the other side of the main plane (4) and may be parabolically curved, which reflector portion has a side axis (22) passing through the optical center (2), and a focus lying in the optical center (2). The side axis (22) is tilted, with respect to the main axis (3), through acute angles in the main plane (4) and out of said main plane (4). The luminaire provides a screened-off light beam which is asymmetrical in horizontal planes as well as in vertical planes, as a result of which said luminaire can suitably be used to illuminate highways in the oncoming-traffic direction.
