Solar Concentrator with Integrated Tracking and Light Delivery System with Summation

摘要

A solar light distribution system includes a solar light concentrator that is affixed externally to a light transfer tube. Solar light waves are processed by the concentrator into a collimated beam of light, which is then transferred through a light receiving port and into the light transfer tube. A reflector redirects the collimated beam of light through the tube to a light distribution port. The interior surface of the light transfer tube is highly reflective so that the light transfers through the tube with minimal losses. An interchangeable luminaire is attached to the light distribution port and provides light inside of a structure. A sun tracking device rotates the concentrator and the light transfer tube to optimize the receiving of solar light by the concentrator throughout the day. The system provides interior lighting that uses only renewable energy sources, and releases no carbon dioxide emissions into the atmosphere.

主权项

1. A solar light distribution system comprising:
a first tubular member extending lengthwise along a central, longitudinal axis (CL1), said first tubular member having a first support wall defining a first light transfer duct having a regular convex polygonal sectional shape, one or more light receiving ports, and a first light delivery port that are optically coupled; one or more solar light concentrators affixed externally to said first tubular member and each one being located proximate to one of the one or more light receiving ports, said light concentrators for receiving solar light waves and directing the light waves through the one or more light receiving ports and into the first light transfer duct; a first turning reflector disposed inside of the first light transfer duct and located proximate to each one of the one or more light receiving ports, each of said first turning reflectors for reflecting the light waves from one of the light receiving ports, down the first light transfer duct, to the first light delivery port; and wherein each of said first turning reflectors includes a deflecting surface that diverts the light waves, introduced through the one or more light receiving ports, away from the first turning reflectors to facilitate a summation of the light waves within the first light transfer duct.
