Tunnelleuchte and tunnel lighting system with a variety of such tunnel lights

摘要

The present invention relates to a tunnel luminaire with an asymmetrical light intensity distribution and a tunnel lighting system, comprising a plurality of such luminaires, which are arranged in a line behind the other over the road and / or on a road side or on two lane sides in the form of a light band. According to the invention, it is provided that the luminous flux of the luminaire is limited to a half-space pointing in the direction of travel, and the luminaire has a masking area which comprises the half-space pointing counter to the direction of travel. By illuminating the tunnel or the road area in the direction of travel, vehicles driving in front of a certain vehicle are illuminated, so to speak, from behind, so that they are clearly visible to the driver driving behind them. This excludes glare from persons traveling in the tunnel, regardless of the luminance of the luminaire in the radiation area (in the direction of travel). In addition, the glare is also eliminated or greatly reduced in the radiation space of the luminaire by means of a light point decomposition by which light impinges on each point of the illuminated surface originating from a large number of separately perceptible points of light which do not exceed a certain size.
