Abstract
Official abstract text for this publication.
An illuminated color display panel having at least one light diffusing waveguide, and a transparent panel having at least one luminophore provided in a predetermined pattern on at least one major planar surface of the transparent panel is provided. Light from at least one light source is coupled to the waveguide and light from the waveguide is coupled to the panel at or adjacent at least one edge of the panel. The resulting illuminated color display panel is useful for general lighting purposes and signage.
First claim
Opening claim text (preview).
What is claimed is: 1. An illuminated color display panel comprising: at least one glass core light diffusing waveguide; at least one light source coupled to the at least one glass core of said at least one light diffusing waveguide; and a transparent panel having at least one major substantially planar surface and at least one luminophore disposed in a predetermined pattern on the at least one major substantially planar surface of the transparent panel, the light being couple…
