| 摘要 |
This invention relates to a solar energy collecting device that concentrates the intensity of the sunlight by funneling the sunlight with one or more light funnels having a substantially V-shaped cross section made of light reflecting surfaces. The sunlight funneled to the apex zone of the light funnel is absorbed by one or more substantially flat fins radially extending a short distance from a conduit and dividing the wedge angle of the light funnel. The sunlight absorbed by the light absorbing fins heats the heat transfer fluid moving through the conduit disposed adjacent and parallel to the apex line of the light funnel. The opening of the diverging end of the light funnel is covered with a simple transparent cover or a two dimensional Fresnel lens cover. The solar trap may be used independently as a solar energy concentrating and collecting device or in conjunction with prefocusing reflectors or lenses.
