Title:
OPTICAL POWER SUPPLY CONVERTER
Document Type and Number:
WIPO Patent Application WO/2022/176185
Kind Code:
A1
Abstract:
[Problem] To provide an optical power supply converter capable of easily increasing the number of optical fiber cables for inputting light, and of receiving all the input light with a light-receiving element to increase output. [Solution] This optical power feeding converter (1) for converting light from optical fiber cables into power and supplying that power has a reflector (3) provided with a concave reflecting mirror (6) having a concave surface of a paraboloid of revolution as a reflective surface, a light-receiving element (2) for photoelectric conversion arranged such that a center of a light-receiving surface (2a) orthogonal to an axis of rotation of the concave reflecting mirror (6) is aligned with the focal point of the concave reflecting mirror (6), and a plurality of mounting parts (9) mounted in parallel to the axis of rotation of the concave reflecting mirror (6) such that output ends (OE) of a plurality of optical fiber cables that output light toward the concave reflecting mirror (6) are spaced apart from this axis of rotation by a predetermined spacing distance, and the output ends (OE) of the optical fiber cables can be mounted in a position closer to the concave reflecting mirror (6) or in a position farther from the concave reflecting mirror (6) by a shift distance corresponding to the spacing distance in the axial direction of the axis of rotation from a plane including the light-receiving surface (2a).
