Title:
PLANAR LIGHT GUIDE
Document Type and Number:
WIPO Patent Application WO/2012/150876
Kind Code:
A3
Abstract:
The invention relates to solar power engineering and, in particular, to solar concentrators. The proposed planar light guide consists of two optical wedges, arranged so that the corresponding working faces thereof are adjacent with a gap therebetween, and a light-deflecting element. The gap between the wedges is filled with an optical medium, and the light-deflecting element can be situated above the light-receiving working face of the first optical wedge, below the working face of the second optical wedge, or in the gap between the wedges. The technical results of the invention are a high concentration factor of solar energy and the manufacturability of the article. Furthermore, depending upon the type of device (light transducer or light source) disposed on the bases of the wedges, the present technical solution can be used as a light concentrator or a light diffuser respectively.
