1. A light collection and distribution system for use in illuminating the interior of a structure comprising:
- a solar collector for use in gathering sunlight, a light dispersion device capable of dispersing light collected by the solar collector for illumination purposes; and
a liquid-filled light guide connected to the solar collector and the light dispersion device for transmission of light from the solar collector to the light dispersion device.

Abstract
A liquid-filled light guide is coupled with a solar collector and a light dispersion device to form a system used to illuminate the interior of a human-inhabitable structure, such as building, underground space or lightless underwater space. The liquid filled light guide establishes a light transmissive pathway that may be split and joined through the use of liquid filled coupling devices.

25. A solar light distribution system, comprising:
-
a tubular structure having a first index of refraction and a diameter greater than one-half inch;
liquid material with favorable optical properties and having a second index of refraction; and
tubular end caps connectable to tubular structure that permits the transmission of light, said liquid material contained within tubular structure by tubular end caps, such that light is permitted to traverse the assembly via total internal reflection, said liquid material being transparent mineral oil with a specific gravity of 0.81 to 0.89, said end caps connectable to other end caps and optical means to support the transmission of light. - View Dependent Claims (30)
