3. lens (lens 22)

   … In other words the light guides comprising the capping lens 22 are generally in the vertical and displaced from the vertical relative to the angles of the sun.

4. lens (lens 22)

   As indicated above the angle of the solar radiation transmitted (passing to focusing lens 24) is dependent on the angle of the incident solar radiation, the wavelength of the solar radiation and the width and length of the guide (reflective surface). The light guides comprising the capping lens 22 are generally in the vertical and displaced from the vertical relative to the angle of

5. light guide lens (light guide lens 22)

   In that the primary directivity of the capping light guide lens 22 (in the vertical) is displaced 90° from the primary directivity of the wall light guide lens 21 (in the horizontal), it can be appreciated that the solar radiation transmitted must be '“'bent” by the wall light guide lens 21 to strike the flat surface of the focusing lenses 26 and 28. …

6. top lens (top lens 22)

   The structure of the overall system of FIG. 1 and particularly the collector lens 20 of FIG. 2 comprising top lens 22 and wall lens 21 can take most any overall configuration - round, square, cylindrical, and so on. …

9. lens (lens 22)

   In certain applications for certain given periods of excess “sun” days, the accumulated heat within the overall collector lens 20 may: exceed a safe standard. To limit the amount of incoming solar radiation a shutter automatically responsive to temperature is movably positioned over the dome 61 of the lens 22. This con-
