Abstract
A solar radiation concentrator consisting of a refractor in the form of at least one strip of transparent material having on it a pattern of prismatic parallel grooves arranged to refract incident solar radiation onto a trough shaped reflector the opening of which is closed by the said strip, a linearly extending target being arranged within the reflector parallel to the axis of the said strip, the strip and the concentrator having optical properties such that in combination the concentration of solar radiation of the target is maximized so as to permit stationary operation of the concentrator without sun-tracking or seasonal orientation.
Claims5
A solar radiation concentrator comprising:
- trough means, having an open portion, for reflecting solar radiation incident thereupon;
- refracting means, covering said open portion of said trough means, for refracting solar radiation incident thereupon onto said trough means, said refracting means comprising at least one strip of transparent material including a pattern of prismatic parallel grooves;
- and
- target means, linearly, extended in said trough means parallel with a longitudinal axis of said strip means, for absorbing solar radiation refracted and reflected thereupon by said refracting means and said trough means, respectively, said trough means including at least two side portions, each of said side portions is a circular curved reflective portion with a center of curvature offset from a center of curvature of the other side portion, and a substantially flat bottom portion, said side portions in combination with said refracting means facilitating the focussing of solar radiation, incident at angles up to 30.degree. from a normal to said refracting means, upon said target means so as to permit stationary operation of said concentrator without sun-tracking or seasonal orientation.
