ABSTRACT:
An illumination device for producing uniform illumination of a surface, comprising several parallel optical conductors which are placed above an optically reflecting surface, and whose reflecting outside sheath is removed locally at least in such a way that the light thereby emerging from the optical conductor is reflected by the reflecting surface to the surface to be illuminated. The optical conductors are spaced at such intervals and placed at such a distance above the reflecting surface that the light reflected by the reflecting surface can reach the surface to be illuminated on the other side of the optical conductors through the space between the optical conductors in such a way that the most uniform possible illumination of said surface is obtained.
