Title
(EN) HIGH EFFICIENCY LIGHT GUIDE
(FR) GUIDE DE LUMIERE A GRANDE EFFICACITE
Abstract
(EN)
The present invention includes a light guide system (200) and a method (300) for increasing the efficiency of light guide systems. The light guide system can include a light conduit (204) for directing light and a reflective material (206) coated to the light conduit without a boundary between the light conduit and the reflective material. The light guide system can also include a light source (202) optically coupled to the light conduit. A method of increasing the efficiency of a light guide system can include the steps of providing (304) a light conduit and coating (306) the light conduit with a reflective material without a boundary between the coating and the light conduit.

L'invention concerne un système de guide de lumière (200) et un procédé (300) permettant d'augmenter l'efficacité de systèmes de guide de lumière. Le système de guide de lumière de cette invention peut comprendre un conduit de lumière (204) destiné à diriger la lumière et un matériau réfléchissant (206) appliqué sur le conduit de lumière sans qu'il y ait de limite entre le conduit de lumière et le matériau réfléchissant. Ce système de guide de lumière peut également comprendre une source de lumière (202) couplée au niveau optique au conduit de lumière. Le procédé de cette invention permettant d'augmenter l'efficacité d'un guide de lumière peut comprendre les étapes consistant à obtenir (304) un conduit de lumière et à revêtir (306) ce conduit de lumière avec un matériau réfléchissant sans limite entre le revêtement et le conduit de lumière.
