Tunnel light and tunnel lighting system with a number of such tunnel lights

摘要

The light i.e. tunnel light (1), has an optics for realization of asymmetric luminous intensity distribution and uniform illumination of a surface of a road (12) or a tunnel (10) and areas lying over the road. Luminous flux of the light is limited to a half-space (21) viewable in a travel direction and lying behind the light. The luminous flux is limited to a cone or club-shaped radiation area (8) whose major axis is acute angularly inclined to the travel direction and directed to the road. A set of punctiform light sources i.e. LEDs, is provided.
