Description

Solar concentrating panels

Technical Field

The invention relates to the field of solar energy concentration.

Background technique

Traditional focusing devices mostly use circular curved mirrors to focus light. This solution occupies a large space, causes serious light pollution, and has a limited scope of use. Based on this, this solution aims to provide a focusing device that occupies a small space, has low light pollution, and has good adaptability.

Summary of the invention

In order to solve the above technical problems, the present invention provides a solar concentrator panel, which can concentrate direct light from a large area panel to one side of the panel to form high-magnification light, and can be applied to the field of solar energy concentration.

The technical solution adopted by the present invention to solve the technical problem is: a solar concentrator comprises a leaf mirror array and a bottom mirror panel;

The leaf mirror array is provided by a plurality of blade arrays;

The bottom mirror panel is arranged below the leaf mirror array and forms a light reflection passage with the bottom surface of the leaf mirror array.

In the embodiment, the leaf mirror array is fixed by sheet metal with grooves, and a transparent glass is arranged above the leaf mirror array for dust prevention. An edge-sealed glass strip is arranged on the light-emitting side of the focusing plate and an edge-sealed mirror strip (the reflective surface faces inward) is arranged on the opposite side.

Preferably, the surface of the blades of the leaf mirror array are all mirror surfaces, the gaps between adjacent blades on the incident light side are large to form a light entrance, and the gaps on the bottom mirror plate side are small to form a light exit, thereby increasing the light collection area.

Preferably, the light outlets of the adjacent blades are biased to one side relative to the light entrance, and the light enters through the light entrance and exits through the light exit, and the direction of the light changes, so as to better constrain the light.

Preferably, the light reflection passage is a single-sided reflection passage, and the light enters the light reflection passage through the leaf mirror array, and is reflected back and forth between the bottom surface of the leaf mirror array and the bottom mirror plate to converge toward one side of the passage, so as to better concentrate the light.

Beneficial effects of the present invention:

This solution can concentrate direct light from a large area panel to one side of the panel to form high-magnification light, and can be applied to the field of solar energy concentration.

Implementation

In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the solar concentrator includes a leaf mirror array and a bottom mirror panel 3 ;

The blade mirror array is arranged by a plurality of blades 2 array;

The bottom mirror plate 3 is arranged below the leaf mirror array and forms a light reflection passage with the bottom surface of the leaf mirror array.

As shown in Figures 6, 7 and 8, the leaf mirror array of the embodiment is fixed with a sheet metal 4 with a groove, a light-transmitting glass 1 is arranged above the leaf mirror array for dust prevention, an edge-sealed glass strip 5 is arranged on the light-emitting side of the focusing plate and an edge-sealed mirror strip 6 (the reflective surface faces inward) on the opposite side.

As shown in FIG4 and FIG5 , the surface of the blades 2 of the leaf mirror array are all mirror surfaces, the gaps between adjacent blades 2 on the incident light side are large to form a light entrance, and the gaps on the bottom mirror plate side are small to form a light exit, thereby increasing the light collection area.

The light outlet direction of the adjacent blades 2 is biased to one side relative to the light entrance direction, and the light enters through the light entrance and exits through the light exit, and the light direction is changed, so as to better constrain the light.

The light reflection passage is a unilateral reflection passage, and the light enters the light reflection passage through the leaf mirror array, and is reflected back and forth and converged toward one side of the passage between the bottom surface of the leaf mirror array and the bottom mirror plate 3, so as to better concentrate the light.

Beneficial effects of the present invention:

This solution can concentrate direct light from a large area panel to one side of the panel to form high-magnification light, and can be applied to the field of solar energy concentration.

The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion within the scope of the claims of the present invention shall fall within the protection scope.
