摘要： An optical element and associated methods for generating an optical element and apparatus comprising the optical element, wherein the optical element comprises a first surface (10), a second surface (15), and a side wall structure (25) between the first and second surfaces. The side wall structure has an internally reflecting profile such that optical radiation incident on the first surface at an angle less than or equal to an acceptance angle and then incident on the side wall structure is internally reflected to the second surface by the side wall structure. In a first cross section of the optical element, the side wall structure has a first internally reflecting profile and/or the first surface has a first cross sectional profile. In a second cross section that is rotated relative to the first cross section, the side wall structure has a second internally reflecting profile and/or the first surface has a second cross sectional profile, wherein the second internally reflecting profile of the side wall structure and/or the second cross sectional profile of the first surface is different from the first internally reflecting profile of the side wall structure and/or the first cross sectional profile of the first surface.

摘要： The present invention relates to apparatus and methods to provide a control system for the purpose of redirecting light from a source onto a target. The present invention appreciates that the diffraction pattern for light that is both diffracted and re-directed by a heliostat is a function of how the light redirecting element is aimed. This means that the aim of the light redirecting element can be precisely determined once the aim of the diffracted light is known. Advantageously, the characteristics of diffracted light indicative of how the diffracted light is aimed can be determined from locations outside the zone of concentrated illumination in which sensors are at undue risk. This, in turn, means that diffracted light characteristics can be detected at a safe location, and this information can then be used to help precisely aim the light redirecting element onto the desired target, such as a receiver in a CSP system. The aim of the diffracted light is thus an accurate proxy for the light beam to be aimed at the receiver.

摘要： A concentrator and a solar light router for converting light energy into electrical, photochemical and thermal energy, among other possible forms of usable energy, comprising a fixed body (1) and a movable part (2), wherein the fixed body (1) has an upper side with a converging lens (4) through which the sun rays (R1) enter, and a lower side where a mirror (5) is arranged. The mobile part 2 has a support arm 7 having a lower leg 8 coupled to a movement unit 10, and an upper leg 9 extending above the converging lens 4, in which is displaceable mounted a module (11) receptor/router of convergent solar rays (R4) that emerges from the fixed body (1). The support (7) is connected to angular displacement means housed in the movement unit (10) so that the angle traveled by its arm (9) encompasses a virtual surface (17), defined between the converging lens (4) and the module (11), where a focal point (19) incise of the convergent rays (R4), that travels according to the curvilinear paths (18n) in accordance with the displacement of the sunlight captured by the converging lens (4). The module (11) presents a lower face (13) through which the converging solar rays (R4) enters, and an upper face (14) from which concentrated solar rays (R5) are emitted which are directed, for example, towards a solar energy converter receiver (20) arranged in a tower (T) spaced from the device. The module (11) is connected to translation means along the upper section (9) of the support (7) and to rotating means with respect to its axis (E1) transverse to the defined plane by the converging lens (4) and includes means detecting the positions of the focal point (19), which together with the angular arm displacement means (7) and the translational and rotational means of the module (11) are connected to a module position control and control unit (11) to maintain it facing the focal point (19) and facing the receiver/solar energy converter (20) of the tower (T). In an alternate realization, the module (11) may act as a solar energy receiver/converter, for which it may include solar cells, a thermoelectric motor, or other solar energy converters.

摘要： An optical device and systems using an optical device are provided, where the optical device may be configured for collimating incoming light rays. The optical device may include a host medium substantially comprised of a transparent material and an array of substantially transparent structures embedded within the host medium. The structures of the 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, collimating the rays. Multiple stages of arrays may be provided in the optical device, typically with lengthening aspect ratios and increasing indexes of refraction in a direction from the input face toward the output face. The systems may use the optical device for using an exterior light to illuminate an interior space in a building or to generate power.

摘要： A solar power method is provided using two-stage light concentration to drive concentrating photovoltaic conversion in conjunction with thermal collection. The method concentrates light rays received in a plurality of transverse planes towards a primary linear focus in an axial plane, which is orthogonal to the transverse planes. T band wavelengths of light are transmitted to the primary linear focus. R band wavelengths of light are reflected towards a secondary linear focus in the axial plane, which is parallel to the primary linear focus. The light received at the primary linear focus is translated into thermal energy. The light received at the secondary linear focus is focused by optical elements along a plurality of tertiary linear foci, which are orthogonal to the axial plane. The focused light in each tertiary primary focus is focused into a plurality of receiving areas, and translated into electrical energy.

摘要： A solar concentrator has frame members connected together to form a framework, and a flexible sheet attached to the framework such that the flexible sheet takes a loose shape and can flex in response to shaping forces exerted thereon. The sheet has a reflective surface located between the frame members. A shaping force system is operative, when activated, to exert the shaping forces on the sheet, the shaping forces configured to draw the sheet from the loose shape into a desired shape such that solar rays striking the reflective surface are focused on a target, and a solar energy receiver is attached to the framework at a location corresponding to the target. Thin wall tubing filled with pressurized air can provide strong light frame members. When the shaping force system is deactivated, the flexible sheet reverts substantially to the loose shape.
