    摘要: A dial illuminating assembly allows for minimum power operation while maintaining uniformity of illumination in a telephone dial. The dial illumination assembly includes a plurality of fiber optic light guides for receiving light rays emanating from a light source and for directing these light rays to a plurality of translucent buttons. Illumination of the translucent buttons is achieved by creating multiple abraded surfaces on the light guides for dispersing the light rays in the vicinity of each translucent button. The light guides are routed along opposed sides of the translucent buttons with abraded surfaces on the light guides being positioned next to each button for providing the desired illumination. The dial illuminating assembly directs light rays so efficiently that only one light source is needed to provide uniform illumination in standard telephone dials.
