SOLAR CONVERGING LIGHT GUIDE SYSTEM

WIPO Patent Application WO/2019/169674

A1

A converging light guide system that outputs sunlight at stable intensity, comprising a converging lens array and an optical fiber (2) as a transmission medium. Sunlight passes through the converging lens array and is converged at the optical fibers (2) corresponding to respective converging lenses (1) and is transmitted. The converging lens array consists of (2n x+1) × (2n y+1) converging lenses (1) arranged in east-west and south-north directions. The light-converging end of the optical fiber (2) is located at a focal point of the converging lens (1) and an optical fiber axis overlaps with a principal axis of the converging lens (1). The converging light guide system moves synchronously with a tracking and positioning device. The number of converging lenses (1) in the converging lens array is sufficient the formula (I). The converging light guide system can effectively reduce a variation in light-converging efficiency caused by a deviation between an actual angle of incidence of sunlight and a designed angle of incidence.
