An optical device for collecting light and selectively outputting or concentrating the light. A layer has an optical index of refraction n, and top, bottom and side surfaces defining an angel of inclination &#x3c6;. A back surface spans the top, bottom and side surface. A first layer is coupled to the bottom surface of the layer and has an index of refraction n. The first layer index ncauses light input through the back surface of the layer to be preferentially output into the first layer. A second layer is coupled to the bottom of the first layer and selectively causes output of light into ambient. Additional layers, such as alight polarization layer, a polarization converting layer and a post LCD diffuser layer can be used to make preferential use of polarized light of diffuse light having passed through the LCD layer to enhance viewing of the output light.

Multilayer luminaire device

A color projection system, comprising a rotatable color drum with reflective segments on the surface of the drum, the segments composed of dichroic filters having different color reflection bands, and means for focussing images of the segments onto a reflective electro-optical light modulator panel, whereby in operation the segment images are scrolled across the surface of the light modulator, synchronously with the application of color components of a display signal corresponding to the colors of the scrolling segment images, to produce a full color display image.
