| 摘要 |
The invention is a radiant energy trap. As a solar collector it can combine diffuse light concentration and hybrid electric and thermal conversion. A refractor comprises a plurality of non-imaging concentrators, each interfaced with a corresponding receiver, adjacent to a reflector, which can be symmetrical or asymmetrical, with optically independent or dependant sections. The refractor can be a composite of layers, solid or nested fluid layers. The fluid can be a transparent refractive component or be optically independent from the refractive function of the invention and can flow through the refractor as a thermal transfer medium. The refractor can selectively direct radiant energy without reducing the collectors angle of acceptance (AOA) of ambient radiant energy, can take advantage of total internal reflection and can be thermally isolated. The invention has a relatively high concentration (CR) of diffuse light when the AOA is equivalent to that of a flat panel collector.
