ABSTRACT:
From a quasi point source, light distribution means produce a selected one or ones of broadly distributed ambient light, non-shadowing task illumination, multibeam display lighting, projective lineal lighting and projective surface washing illumination lineally or radially distributed. Collimation optics shape light from a quasi point source into a disc of selected axial thickness. Containment optics contain divergence of and direct light from the collimation optics to distribution optics. The distribution optics modulates and redirects the radiant energy into a shape or shapes useful in illuminating architectural space. The distribution optics may reflect or refract light to direct and shape it for a particular architectural illumination requirement. The efficient combination of the optics provides for a system of minimized thickness, permitting maximum flexibility in integration with or within shelves, soffits and other structural members.
