1. A solar lighting reflector apparatus for illuminating the interior of a roofed building during daylight hours and adapted to follow daily movements of the sum, the roofed building having a light transmissive opening in the roof thereon, said apparatus comprising:

  • a plurality of generally planar reflective panels for reflecting sunlight into the light transmissive opening, each of the reflective panels extending between first and second opposing ends along a generally horizontal longitudinal axis, the longitudinal axes of the plurality of reflective panels substantially being parallel to each other, the plurality of reflective panels including at least a frontmost reflective panel and rearmost reflective panel, the rearmost reflective panel being supported at a higher elevation than the frontmost reflective panel to avoid shading of the rearmost reflective panel by the frontmost reflective panel;

    means for supporting said reflective panels above said light transmissive openings;

    means coupled to said reflective panels for rotating said reflective panels when driven by a rotation force;

    a rotatable shaft connected to said coupling means;

    means for coupling the output shaft of a d.c. motor to said rotatable shaft whereby the reflective panels are directed to the sun as the sun moves throughout the day; and

    a worm gear and stepper wheel mounted to said rotatable shaft.
