<p><P>PROBLEM TO BE SOLVED: To provide an edge lighting system for interactive display surface. <P>SOLUTION: The edge lighting system has a plurality of light sources 66 mounted at spaced-apart intervals along a rail 100 that is disposed adjacent to an edge 114 of a display surface 64a. Openings 90 formed in the rail in which the light sources are inserted are sized to enable each light source to move freely into contact with the edge of the display surface when urged by a force provided by a compressed elastomeric member 108 to provide a uniform illumination as the light is internally reflected in the material comprising the display surface. The light sources extend beyond a concave (paraboloid) surface 112 on the rail that reflects the light from the light sources into the edge. Any object approaching the display surface is illuminated by the light being conveyed within the material. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
