An optical element is provided with an optical layer in which a concavo-convex surface is formed on the surface thereof, and a wavelength-selective reflection layer formed on the concavo-convex surface. The wavelength-selective reflection layer directionally reflects light having a specific wavelength band selectively, while transmitting light having wavelength bands other than the specific wavelength band. The concavo-convex surface is provided with a plurality of first structural elements that are extended in a first direction within the surface of the optical layer and a plurality of second structural elements that are extended in a second direction within the surface of the optical layer, and placed to be spaced apart from each other, with the first direction and the second direction intersecting with each other.

A device for performing solar shade analysis combines a spherical reflective dome and a ball compass mounted on a platform, with a compass alignment mark and four dots in the corners of the platform. A user may place the device on a surface of a roof, or in another location where solar shading analysis is required. A user, while standing above the device can take a photo of the device. The photographs can then be used in order to evaluate solar capacity and perform shade analysis for potential sites for solar photovoltaic systems. By using the device in conjunction with a mobile device having a camera, photographs may be taken and uploaded, to be analyzed and processed to determine a shading percentage. For example, the solar shade analysis system may calculate the percentage of time that the solar photovoltaic system might be shaded for each month of the year. These measurements and data, or similar measurements and data, may be valuable when applying for solar rebates or solar installation permits.

A solar-shading assembly for fastening to a support mullion, comprises an elongate louver member having longitudinal front and rear edges, an elongate cap element for extending along and covering the rear edge, a bracket which is connectable to the support mullion, and a fastening device for connecting the bracket to the rear edge of the louver member. The in use fastening device is coverable by the cap element so as to hide the fastening device from view. Preferably, at least part of the bracket is also coverable by the cap element so as to hide the said part of the bracket from view.

The invention discloses a solar shielding device for an automobile. The device comprises a machine body, and the machine body is installed at the top end of an automobile. An accommodating cavity is formed in the machine body; chutes are formed in the left side and the right side of the accommodating cavity in a communicating mode; lifting devices are arranged in the chutes; each lifting device comprises a sliding rod; a first rotating rod and a second rotating rod are arranged on each sliding rod in a crossed manner; a lifting block is hinged to the upper ends of the first rotating rod and the second rotating rod; according to the invention, the solar panel is mounted on the sun shield; when the sun shield is used, solar energy can be converted into electric energy to be stored through the solar panel; the device is used for supplying power to a motor in the device and an automobile; and the sun shield is arranged at the top of the automobile, the illumination effect is good, the conversion rate of electric energy is increased, the sun shield can be driven by the adjusting device to swing front and back to shield different areas including the front glass and the rear glass of theautomobile, automatic operation is achieved, manpower is saved, and when not used, the sun shield can be contracted and placed, does not occupy the internal space of the automobile and is convenient to use.

The invention relates to a machine and method for the semi-continuous cold-bending of sections (3) with low ductility, of the type including a horizontal mount (1) and an interchangeable tool (4) against which the section (3) is bent. The machine includes a gantry support (10). The tool (4) is located in a zone delimited by the mount (1), vertical supports (5) for the tool (4), and a compression plate (7) actuated by vertical pressure cylinders. The tool (4) is positioned facing an actuation plane defined by a double set of hydraulic positioning (23) and push (20) cylinders. The bent sections (3) can be used for tents, skylights, facades, solar shading louvres, or three-rail frames for truck tarps, guaranteeing a uniform bend in all bent sections, without the section becoming pinned in the machine during bending.

An optical body includes a first optical layer having a random concave-convex surface, a reflecting layer formed on the concave-convex surface, and a second optical layer formed on the reflecting layer to embed the concave-convex surface, wherein the reflecting layer is a wavelength-selective reflecting layer for diffusely reflecting, of incident light, light in a specific wavelength band and transmitting light other than the specific wavelength band therethrough.
