ABSTRACT:
A solar clock utilizes the sun's radiant energy to illuminate a digital display in accordance with the solar time. An opaque mask member, preferably in the form of a right circular cylinder, is provided with a series of sunlight-transmitting apertures which cooperate with a plurality of strategically positioned fiber optic arrays, operatively coupled to a light-responsive digital display, to provide an indication of the solar time. During the course of travel of the sun across the sky, the sun illuminates different fiber optic arrays through the mask. The fiber optics serve to couple the sun's energy to the digital display.
