Title
(EN) OPTICAL SYSTEM FOR MANIPULATION AND CONCENTRATION OF DIFFUSE LIGHT
(FR) SYSTÈME OPTIQUE DE MANIPULATION ET DE CONCENTRATION DE LUMIÈRE DIFFUSE
Abstract
(EN)
The present invention relates to an optical system for concentrating incoming light comprising a plurality of concentrating optical elements (100) with a front surface (102) arranged to receive incoming light and a back surface (103) arranged to exit light, wherein the front surface is larger than the back surface. Adjacent concentrating optical elements are separated by gaps (101) and the refractive index of the material in a concentrating optical element is higher than the refractive index of the gap. The geometry of the concentrating optical elements is optimized to enhance the light concentration.
(FR)
La présente invention concerne un système optique de concentration de lumière entrante, comprenant une pluralité d'éléments optiques de concentration (100) ayant une surface avant (102) disposée pour recevoir la lumière entrante et une surface arrière (103) disposée pour laisser sortir la lumière, la surface avant étant plus grande que la surface arrière. Des éléments optiques de concentration adjacents sont séparés par des espaces (101) et l'indice de réfraction du matériau dans un élément optique de concentration est supérieur à l'indice de réfraction de l'espace. La géométrie des éléments optiques de concentration est optimisée pour améliorer la concentration de la lumière.
