Abstract
An illuminating display including a transparent substrate in the form of a sheet or slab having an upper face, a lower face and a plurality of edge faces. The edge faces are provided with an internally reflective treatment and at least one light source associated with the substrate, causing a relatively narrow beam of light rays to emanate into said substrate. At least one reflective surface arranged internally of said substrate to operatively internally reflect light rays from said at least one light source within the substrate. Either (or both) the upper face and the lower face having material in contact therewith for directing light from within the substrate out of a face. The display may be employed in combination with a liquid crystal display (LCD) assembly.
Claims31
An illuminating display including:
- a transparent substrate in the form of a sheet or slab having an upper face, a lower face and a plurality of edge faces;
- the plurality of edge faces provided with an internally reflective treatment;
- at least one light source associated with the substrate, causing a relatively narrow beam of light rays to emanate into said substrate;
- a plurality of semi-circular reflective surfaces extending from at least one of said edge faces and arranged internally of said substrate to operatively internally reflect light rays from said at least one light source within the substrate;
- and
- at least one of the upper face and the lower face having light capturing material in contact therewith for directing internally reflected light outwardly of the substrate.
The illuminating display of claim 4, wherein each said air-gap has a further light source located therein to provide further rays of light to emanate with said substrate.
An illuminating display including:
- a transparent substrate having a viewing face;
- at least one light source located within said substrate producing a relatively narrow beam of light rays;
- a plurality of semi-circular reflective surfaces arranged laterally with respect to the viewing face and extending from an edge face of said transparent substrate to operatively internally reflect light rays from said at least one light source;
- and
- at least one face of the substrate having material in contact therewith for directing internally reflected light from within the substrate to illuminate a selected portion of the substrate.
