OPTICAL POWER SUPPLY CONVERTER

An optical power supply converter () that photoelectrically converts light from optical fiber cables comprises a reflecting unit () including a concave reflecting mirror () made of a rotating paraboloid, a light receiving element () including a light receiving surface () at the focus of the mirror () orthogonal to the rotation axis of the mirror (), and a plurality of mounting portions () for mounting the emitting ends (OE) of the fiber cables. The seperation distance (s), the shift distance (h) and the divergence angle (θ) are set appropriately so as to concentrate all reflected light on the light receiving surface ().
