Abstract: The parabolic trough collector has a receiver formed by several single absorber tubes (13). The single absorber tubes (13) are supported by absorber tube supports (14) and surrounded by a glass tube (15). Because of different expansion behavior of the absorber tube (13) and the glass tube (15) during collector operation flexible unions (17) are foreseen between absorber tube (13) and glass tube (15). In order to use the radiation coming to the non active-area where the absorber tube supports (14) and the flexible unions (17) are installed a mirror collar (20) is installed on this area. The mirror collar (20) is able to reflect the solar radiation, which is coming from different directions, to the active absorber part of the single absorber tubes (13) also when the sun incident angle is changing.

Abstract: A light guide apparatus that can redirect light impinging on the apparatus over a wide range of incident angles and can concentrate light without using a tracking system and methods for fabrication. This apparatus uses conditions of total internal reflection and refraction near the critical angle for total internal reflection (near TIR) in order to trap light within the apparatus.

Abstract: An apparatus designed to direct daylight through an aperture toward a target area in a building or other structure is disclosed. A housing provides a base attachable to the building and a support structure for supporting a reflector above the aperture. According to one embodiment of the invention the reflector is in the shape of an inverted cone. A light diffusing lens structure is disposed in the optical path between the reflector and the target area. In use, light is transmitted through the support structure, reflected from the surface of the reflector, and dispersed about the target area by the light diffusing lens structure.

Abstract: A solar concentrator utilizes an arrangement of an outer reflective ring around a centrally located inner reflective cone to concentrate light. The reflective surface of the outer reflective ring is substantially 45 degrees from a transmitted light source. Light from the light source is reflected off of the outer reflective ring to produce a reflected light having a light reflective axis. The reflected light is directed toward the inner reflective cone and is reflected off of the reflective surface of the inner reflective cone as transmitted light toward alight receiver. The reflective surface of the inner reflective cone is configured at 45 degrees from the light reflective axis. The light receiver may convert the transmitted light into electricity or heat a fluid or other article. A solar tracker may be used to keep the central axis of the solar concentrator aligned with the sun.

Abstract: Implementations of a system for collecting radiant energy with a non-imaging solar concentrator are provided. In some implementations, the system may be configured to focus radiant energy striking a plurality of concentric, conical ring-like reflective elements of the non-imaging concentrator onto a receiver positioned thereunder and to rotate and/or pivot the receiver so that at least a portion thereof is always kept within the focal point (or area) of the non-imaging concentrator. Wherein the center of the focal point (or area) is fixed with respect to the ground. In some implementations, the system for collecting radiant energy with a non-imaging solar concentrator may comprise a tracking apparatus configured to support the non-imaging concentrator and position it so that the sun is normal thereto, and a piping system that is configured to transfer concentrated solar energy from the receiver to an absorbing system where the energy is finally utilized.

Abstract: A heat receiver, a reactor, and a heater utilize the heat of concentrated solar light for thermal decomposition and/or chemical reaction of coals, etc. The heat receiver includes: a side portion forming a substantially cylindrical side surface; a substantially circular bottom portion connected to the lower edge of the side portion; and a ceiling connected to the upper edge of the side portion. A substantially circular aperture is formed in the center of the ceiling. The heat receiver has a substantially cylindrical cavity and the opening portion is open. When the cavity has a diameter of D and a length of L, and the aperture has a diameter of d, d=D/2 or less and L=2D or more. Concentrated solar light entering the heat receiver is to be contained in the heat receiver to effectively utilize the solar light.
