Secondary Reflectors for Solar Collectors and Methods of Making the Same

Guangdong Zhu (Inventor)

Research output: Patent


The present disclosure relates to a device that includes a reflecting surface having a length aligned along a first axis (z), where a cross-section of the reflecting surface in a plane perpendicular to the first axis (z) forms a curve comprising a concave section positioned between a first endpoint and a second endpoint, at least a portion of the concave section is accurately approximated by a polynomial equation, an aper­ture is formed by a straight line connecting the first endpoint to the second endpoint, and the concave section is config­ured to focus a plurality of beams of light passing through the aperture onto a focal point.
