Abstract
A light collection systems with at least one light receiving element, such as a window, a photovoltaic element, a heating element, a light guiding element or combinations thereof, and at least one light reflector-deflector element. The light reflecting elements include a front light receiving surface, a rear surface, and a transparent volume, disposed between the front light receiving surface and the rear surface, the transparent layer being of a higher refractive index than of its surrounding. The transparent volume comprises an asymmetric pattern which is configured to at least partially reflect light by internal reflection and direct the light within the element, reflect some light off said front light receiving surface, reflect, deflect and guide light within the light reflector-deflector element; and direct light through the front light receiving surface towards the at least one light receiving element.
