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.

Light with a transparent panel

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