Multi-directional non-imaging radiations concentrator and/or deconcentrator device

摘要

The device comprises an extension of a radiation conductor of constant cross-section, having a radiations-confining interface of truncated shape, of which the directrices and generatrices can be any type. According to the invention, said device comprises at least a second radiations-confining interface of conical shape situated inside the first interface, the distance between these two radiations-confining interfaces being substantially constant, and said two interfaces facing in such a way that the radiations are confined between them and propagate towards or from the widened end of the interface opposite the conductor.
