<p>A fiber optic display sign for outdoor use includes a number of fiber optics (14) having light receiving ends (16) for receiving an image from image generator (15). An array of lenses which may be fixed or movable is positioned adjacent the output ends (16) for directing light to control the viewing angle of the image displayed. The image generator (15) employs a light source (66) formed of a densely packed array of white light emitting diodes and a number of image bearing transparencies (54) mounted on a movable support to position a selected transparency between the light source (66) and the light receiving ends (16). The viewing angle and/or the image displayed is automatically controlled and/or remotely controlled.</p> |
