Abstract
A light-weight and energy-efficient lighting panel is constructed from a light-transmissive and light diffusive extrusion formed to have elongated hollows, which are hollow structures or volumes between two surfaces, at least one of which is transmissive and diffusive. Light projected into the hollow flows through the hollow and part of the light is emitted through the light transmissive and diffusive surfaces. Even though the light sources are located at the edges of a panel, the surface of the panel appears to be uniformly light by light sources distribute directly behind the panels rather than along the edges.
Claims6
An illumination device comprising:
- a panel comprised of a plurality of elongated hollows, each hollow having first and second opposing ends, first and second spaced apart, substantially parallel and adjacent web sections, and at least one light transmissive side;
- and
- a plurality of light sources, wherein light sources are coupled to both ends of the plurality of the hollows, each light source directing light into a corresponding hollow;
- wherein the plurality of light sources are configured such that at least part of a light source is within the illumination panel, and located at least partially between first and second sides and between the first and second adjacent web sections;
- and
- wherein light emitted from the light sources that are within the illumination panel travels through the corresponding hollow and at least part of the emitted light passing through the hollow passes through the at least one light transmissive side.
