Abstract

The light has a filament (26) arranged along a longitudinal optical axis (A-A) for producing a light beam. A reflecting unit reflects a channelised lateral part of the light beam towards the front of the light to transversally spread the light beam on a back face (52) of a protection glass (20). The filament images that are emitted towards the front of the light are oriented horizontally on a screen placed at the front.
