The optical structure includes: a planar optical waveguide which has a parallel first and second planar waveguide surfaces, wherein the first planar waveguide surface extends parallel to the redirected light emitting surface, wherein the first planar waveguide surface is at least partially covered by a photonic layer which is configured to provide an angular restriction of a light emission from the planar waveguide through the redirected light emitting surface, and a light scattering and/or luminescent material, which material is arranged as particles in the planar optical waveguide and/or in a layer which at least partially covers the second planar waveguide surface.

A heliostat frame includes a primary beam and several secondary beams arranged on the primary beam at intervals. The secondary beams are fixed on the primary beam along an extending direction of a center axis of the primary beam, and the secondary beam is provided with several supporting block assemblies.

A height of each of the supporting blocks is configured according to its position on the secondary beam, so that a line connected by centers of top surfaces of all of the supporting blocks on the secondary beam is arc-shaped. The heliostat frame reduces the requirements for the manufacturing accuracy of the secondary beam while guaranteeing surface accuracy of the heliostat, thereby effectively reducing the production costs and improving the manufacturing efficiency.

The invented optical chamber is sealed and encapsulated by a transparent element, a connection element and a transparent substrate or another transparent element. The optical chamber is filled with a transparent fluid and equipped with an electronic sensing and execution component.

The parabolic trough solar concentrator described within is sized for shipping in containers and mounting on existing structures without requiring specialized labor or equipment. Besides achieving a proximity to the thermal load not previously achievable economically and preserving precious land, the concentrator array shelters the area below from the sun reducing its energy requirement for cooling and making it more inhabitable when cooling is not provided. As the troughs are generally mounted on an incline on roof structures, they can provide for rainwater collection.
