Abstract
A passive solar lighting system is disclosed. A multiplyer lens (20) located within an aperture (12) in a building (10) increases the cone of light acceptance which would result in the absence of lens (20). Light passing through lens (20) is further refracted by lenses (22, 24) and the resultant light is thereby directed to a target area (14) for interior lighting.
