Patent attributes
A solar concentrator may include a substantially planar surface, a curved primary mirror having a first perimeter, at least a portion of the first perimeter being in contact with the substantially planar surface, a secondary mirror disposed between the substantially planar surface and the curved primary mirror, the secondary mirror associated with a desired focal area, and a shield element disposed between the substantially planar surface and the curved primary mirror. The shield element is to prevent a portion of light reflected by the secondary mirror from reaching the primary mirror. In some aspects, a portion of the shield element may be disposed between the substantially planar surface and a plane which is substantially parallel to the substantially planar surface and which includes a portion of the desired focal area. The shield element may include a reflective surface to reflect light received from the secondary mirror toward the desired focal area.
