Abstract

On a light signal, for example a traffic signal, to reduce the parasite reflections of an external light source (for example the sun), a series of parallel, superposed lamellae are arranged between the light source and the dispersion glass (2). At least a portion of the upper surface (4) of these lamellae particularly more exposed to the external light source is highly light absorbing, whereas the other surface (5) is preferably highly reflecting. Conveniently, the position of the lamellae (3) is adjustable.
