Abstract: The invention relates to a light comprising a light source or connection means for a light source, and a transparent panel which extends crosswise to a direction of light emission. An object of the invention is to improve the light in terms of glare suppression. To this end, the transparent panel is provided with a microstructure and light homogenization means are provided. The latter ensure that the brightness of the light entering the panel is approximately equal in all parts of the panel.

Abstract: An optical element (1) for reflecting and/or redirecting light rays (L1) entering therein and again emerging therefrom consists of a transparent base body (2) which is so structured and/or formed that, with the formation of reflection surfaces (8) bounding the base body (2), at least a part of the light rays (L1) impinging upon the reflection surfaces (8) upon emergence from the transparent base body (2) are totally reflected, and at least one cover body (9) arranged behind the reflection surfaces (8). The reflection surfaces (8), and the surfaces of the cover body or bodies (9) towards the reflection surfaces, are adapted to one another such that between them there remains a thin gap (10) or only point contacts exist.

Abstract: A light (1) comprises a light source (4) and a wedge-shaped light guiding element (3) having two wedge surfaces (11, 13) and a light entry face (10) extending between the wedge surfaces where they are farthest apart. Light from the source (4) enters light guiding element via the face (10) and is reflected by one wedge surface (13) against the other wedge surface (11) where it exits from the light guiding element (3). To improve radiation characteristics, the other wedge surface (11), which is an exit surface, is profiled with adjacent elevations and indentations extending crosswise to the direction of the wedge. A transparent diffuser (20) is positioned at a distance in front of the exit surface (11). The side of the diffuser (20) facing away from the light exit surface is profiled with adjacent elevations and indentations. The distance between the diffuser (20) and the light guiding element (3) prevents light from entering the diffuser at any angle and thus increases the effectiveness of the profiling.
