The light i.e. tunnel light (1), has asymmetrical lenses (3) associated to point light sources (2) i.e. LEDs, for achieving an asymmetric luminous intensity distribution and illumination of a tunnel surface. The lenses are formed so that luminous fluxes delivered by the sources radiate in a driving direction and are limited in a half-space, which lies behind the sources in the direction. The lenses are exposingly arranged and include a bump-like edge elevation on a side that turns against the direction. An outer side of the elevation is provided with an inward effective reflective coating. The lenses are anchored on a carrier surface by a hardening binding agent i.e. synthetic resin. |
