Light ray concentrator

A system for using an exterior light for illuminating an interior space in a building, the system comprising an external portion and an internal portion,

• the external portion including an optical device and a coupler for interfacing with a fiber optic cable, and
• the internal portion including a diffuser coupled to the fiber optic cable,
• wherein the optical device includes
• a. a host medium substantially comprised of a transparent material, the host medium providing the input face and the output face;
• and
• b. a first array of substantially transparent structures embedded within the host medium, the first array substantially parallel to the input face of the host medium, and wherein the structures of the first array each include a convex side presented to the incoming light rays and a concave side that passes light rays through toward the output face of the host medium.

A system for generating power from a light source, the system comprising:

• a collimating lens, a focusing lens, and a power generation component,
• wherein the collimating lens includes
• a. a host medium substantially comprised of a transparent material, the host medium providing the input face and the output face;
• and
• b. a first array of substantially transparent structures embedded within the host medium, the first array substantially parallel to the input face of the host medium, and wherein the structures of the first array each include a convex side presented to the incoming light rays and a concave side that passes light rays through toward the output face of the host medium.
