ABSTRACT:
An active solar reflector, preferably mounted within a transparent dome, tracks the sun from sunrise to sunset to reflect impinging solar radiation into a room or other space to be lighted. The reflector includes a plurality of angled mirrors mounted one behind the other and of progressively increasing heights to intercept and reflect as large a flat plate area of solar radiation as possible. The mirrors are mounted upon a support rotatable about an axis to track the sun and to have the mirrors continuously reflect the impinging solar radiation.
