CA 2216945

The light sources provided give off light in all directions. If a light source at the edge of a planiform lamp which radiates into the lamp is attached or imbedded at the edge, it is apparent that a large portion of the light at the edge of the surface to be illuminated leaves the lamp (visible as a bright edge etc.). This effect occurs in all known arrangements because in this region the light strikes the surface with a smaller angle than the angle of total reflection, and for the most part exits. This natural characteristic considerably limits the use of radiated light for the lighting effect in the entire area of the lamp. An essential major feature of this patent application is how to compensate for this effect and thus the possibility of using the portion of light normally ignored in known applications.

L'invention concerne des sources lumineuses permettant un rayonnement de la lumière dans toutes les directions. Lorsqu'une source lumineuse est montée sur le bord d'une lampe en deux dimensions ou incorporée dans une zone du bord, avec rayonnement dans la lampe, on observe qu'une grande partie de la lumière au bord des surfaces à éclairer quitte la lampe (visible sous forme de bord clair etc.). Cet effet apparaît dans tous les dispositifs connus car la lumière dans cette zone frappe la surface avec un angle inférieur à l'angle de la réflexion totale, et donc sort en grande partie. Cette propriété naturelle limite considérablement l'utilisation de la lumière émise pour l'effet d'éclairage dans l'ensemble de la lampe. La compensation de cet effet et par conséquent la possibilité d'utiliser la partie de la lumière non prise en considération dans les applications connues constitue l'une des caractéristiques principales de cette invention.
