Abstract
A lumenaire system for providing illumination by distributing and mixing light from multiple sources of illumination which includes a first light source providing Lambertian light radiation and a second light source providing collimated illumination. There is a prismatic light guide structure having at least two functions, the first function being to refract the light radiation from the first light source disposed as to at least partially surround the light source, and the second function is to guide and distribute light from the second light source so as to mix it with light from the first light source.

A lumenaire system for providing illumination by distributing and mixing light from multiple sources of illumination comprising:
- a. a first light source providing Lambertian light radiation;
- b. a second light source providing collimated illumination;
- and
- c. a prismatic light guide structure having at least two functions, the first function being to refract the Lambertian light radiation from said first light source disposed as to at least partially surround said light source and the second function being to guide and distribute collimated light from the second light source so as to mix it with light from said first light source.
A lumenaire system for providing illumination by distributing and mixing light from multiple sources of illumination comprising:
- a. a first light source providing Lambertian light radiation;
- b. a second light source providing collimated illumination;
- and
- c. a prismatic structure having at least two functions, the first function being to refract the Lambertian light radiation from said first light source;
- and the second function being to redirect said collimated light through internal reflection from said second light source and mix it with said light from said first light source.
In a lumenaire having a light source and an optic system having a refracting function, the improvement comprising:
- a component of the light system for providing the refracting function of variably changing the distribution of light rays from the light source entering said component, said component being a flexible plastic film having prism structures, said component having a changeable curvature which is changed by a mechanical force,
A lumenaire system for providing illumination comprising:
- an array of light projecting panels for providing a first light source, each said panel including at least one LED light source mounted to a heat sink;
- a collimating optic at least partially surrounding each LED, said collimating optic functioning to project light out of at least one edge of said panel;
- a second light source;
- the array of panels being disposed to form openings between the panels to allow light from said second light source to pass through the openings;
- the surfaces of the sides of the light projecting panels including a light controlling material to alter the distribution of light from said second light source passing through the openings between the light projecting panels.
