NOVELTY - The apparatus has a light guide component including an injection layer section placed adjacent to a light guide layer section. An index of refraction of the injection layer section is greater than an index of refraction of the light guide layer section by an amount greater than zero. A lens array is placed adjacent to the light guide component. An axial gradient index of a light guide layer does not extend for more than 20 percentages of thickness of the guide layer. A total internal reflection (TIR) layer is adjacent to the guide layer section that is not adjacent the injection layer section.    USE - Light guide apparatus for collecting and emitting light for lighting applications in a concentrated photo-voltaic (CPV) solar energy system.    ADVANTAGE - The CPV solar energy system is more efficient, lower in cost and easier to manufacture. The apparatus can be redirected to travel down a guide at a lower angle relative to a guiding axis for more efficient collection, propagation, emission and overall system operation, thus allowing light to be contained in the guide for a longer propagation distance, and hence increasing concentration that the system can achieve. The apparatus allows a one-sided system to be folded in half such that thickness of the one-sided system is reduced, thus reducing weight and material used. The apparatus allows lenslets and dimples to be formed by a tool and formed in potentially same process step, thus minimizing registration errors from a given manufacturing technology. The apparatus allows a high index glass to increase usable injection angles and to gain added concentration in a secondary concentrator. The apparatus allows a borofloat glass which is less expensive and has relatively high transmission, thus offering a commercial solution in an efficient manner. The apparatus utilizes a seemingly odd irregular mirror perimeter shape to maximize offset and area for the 100 jtm sag over a less efficient faceted Fresnel mirror, and to improve coupling into the guide layer. The apparatus is improved upon in many ways to more closely resemble optimally designed performance. The apparatus allows a bypass element to reduce disruption, thus decreasing loss and increasing maximum out-coupled light concentration.    DETAILED DESCRIPTION - The guide layer is glass and plastic material, and the injection layer section is thermoplastic and a silicone material. An INDEPENDENT CLAIM is also included for a solar light guide.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a multi-surface by-pass prism dimple with un-tilted reflection surfaces.
