Title: Solar concentrator with integrated tracking and light delivery system with summation

Abstract

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.

  • A nontracking solar concentrator with a high concentration ratio is provided. The concentrator includes a plurality of energy absorbers which communicate with a main header by which absorbed heat is removed. Undesired heat flow of those absorbers not being heated by radiant energy at a particular instant is impeded, improving the efficiency of the concentrator.
  • Automatic tracking of a source of radiant energy to pivotally displace an energy collector panel assembly for optimum concentration of the radiant energy absorbed is disclosed. Changes in magnitude and/or location of the source relative to the collector produces a change in differential air pressure in a sensor to displace the center of mass of a gravitational drive device through which tracking movement is imparted to the collector panel assembly.
