[0050] In one embodiment, a solar energy utilization device is provided, which is a solar energy utilization device with focusing and heat dissipation or heat utilization functions, which is used to receive and utilize sunlight for energy conversion, and convert sunlight into electrical energy, thermal energy and other forms of energy for people to use.

[0051] This solar energy harnessing device is equipped with a wasp-waisted concentrating lens. This transparent wasp-waisted concentrating lens increases the light-collecting surface of the light energy harnessing unit, thereby increasing the solar energy harnessing device's light collection area and, in turn, improving the device's power generation and efficiency. Deploying this solar energy harnessing device to generate electricity yields more power than conventional solar energy harnessing devices. For a given power generation output, the number of deployed solar energy harnessing devices can be reduced, thereby lowering costs.

[0052] Please refer to Figures 1a and 1b. A solar energy utilization device in one embodiment mainly includes a solar energy concentrating unit F. The solar energy concentrating unit F includes a first light energy utilization unit F100, a second light energy utilization unit F200 and a focusing lens F300. The focusing lens F300 is located in the middle, and the first light energy utilization unit F100 and the second light energy utilization unit F200 are respectively located at both ends of the focusing lens F300. For example, the focusing lens F300 is installed vertically, the first light energy utilization unit F100 is located at the upper end of the focusing lens F300, and the second light energy utilization unit F200 is located at the lower end of the focusing lens F300.

[0053] The focusing lens F300 has a wasp-waist structure. The two ends of the focusing lens F300 are large and the middle is small, and the two ends gradually become smaller towards the middle, so that the focusing lens F300 can converge the collected light to the two ends respectively. The focusing lens F300 includes a first lens portion F310 and a second lens portion F320. The first lens portion F310 and the second lens portion F320 are both convex focusing lenses. The first lens portion F310 and the second lens portion F320 both have a first end and a second end. When the focusing lens F300 is installed vertically, the first end F311 of the first lens portion F310 is the upper end, the second end F312 of the first lens portion F310 is the lower end, the first end F321 of the second lens portion F320 is the upper end, and the second end F322 of the second lens portion F320 is the lower end.

The vertical and horizontal directions described in this and other embodiments are based on the placement orientation shown in Figures 1a and 1b . Because the solar energy utilization device may be adjusted in actual use based on terrain and latitude and longitude, the placement orientation shown in the illustrations may differ from the actual placement of the solar energy utilization device.

[0091] Specifically, please refer to Figures 1a and 1b. The wasp-waisted solar concentrating unit F in the solar energy utilization device of this embodiment includes a first light energy utilization unit F100, a second light energy utilization unit F200 and a focusing lens F300. The first light energy utilization unit F100 includes a first light energy utilization part F110 and a second light energy utilization part F120. The lighting surface of the first light energy utilization part F110 is set upward, and the lighting surface of the second light energy utilization part F120 is set downward and facing the focusing lens F300.

[0092] The second light energy utilization unit F200 can be double-sided lighting, and the second light energy utilization unit F200 includes a third light energy utilization part F210 and a fourth light energy utilization part F220. The lighting surface of the third light energy utilization part F210 is set upward and toward the focusing lens F300, and the lighting surface of the fourth light energy utilization part F220 is set downward.

[0093] The second light energy utilization unit F200 can also be single-sided lighting. The second light energy utilization unit F200 includes a third light energy utilization portion F210. The lighting surface of the third light energy utilization portion F210 is arranged upward and faces the focusing lens F300.

[0094] The first light energy utilization part F110 can directly receive and utilize sunlight from the top, and the wasp waist-shaped focusing lens F300 can converge sunlight from the side to the second light energy utilization part F120 of the first light energy utilization unit F100 or the first light energy utilization part F210 of the second light energy utilization unit F200.

[0095] Referring to Figure 1a, in one embodiment, the wasp-waisted solar concentrating unit F is a strip-shaped structure, and the wasp-waisted solar concentrating unit F can be used alone. Referring to Figures 3 to 5, in other embodiments, multiple strip-shaped solar concentrating units F can be stacked together and used together. Multiple solar concentrating units F can form a vertical solar wall to improve the efficiency of light collection and charging. Specifically, when two strip-shaped solar concentrating units F are stacked, the second light energy utilization unit F200 of the upper solar concentrating unit F and the first light energy utilization unit F100 of the lower solar concentrating unit F are redundant, so one of them can be omitted.

[0096] Referring to Figure 1b, in one embodiment, the wasp-waist-shaped solar concentrating unit F has a circularly symmetrical structure, i.e., a conical structure. This solar concentrating unit F can be equipped with a circularly symmetrical reflector to provide 360° daylighting, useful in a sun-following system to achieve a high concentration ratio.

[0097] In this embodiment, the wasp waist solar concentrating lens F300 is realized by transparent plastic containing deionized water or a mixture of deionized water and other transparent solutions. In other embodiments, the wasp waist solar concentrating lens F300 can be realized by transparent glass or transparent plastic.

[0098] In this embodiment, the cross-sectional contour lines of the wasp-waisted condenser lens F300 are two intersecting straight lines, and the cross-section is two symmetrical triangles. In other embodiments, the cross-sectional contour lines of the wasp-waisted condenser lens F300 may be two quadratic curves with opposing apexes. For ease of processing and installation, the waist of the wasp-waisted condenser lens F300 may have a certain width, as shown in Figure 1b. The wider the waist of the liquid wasp-waisted condenser lens F300, the better its heat transfer performance.

[0099] Example 2:

[0100] Please refer to FIG2 . This embodiment provides a solar energy utilization device. FIG2 shows a vertical cross-sectional schematic diagram of the solar energy utilization device.

[0101] The solar energy utilization device includes a wasp waist-shaped solar concentrating unit F, which includes a first light energy utilization unit F100, a second light energy utilization unit F200, a concentrating lens F300, a reflector 400, a transparent top cover 500, a thermal function component 600, and a functional cavity 700.

[0102] Reflector 400 and other components enclose a closed functional cavity 700, which is filled with a cooling medium 720. This cooling medium can exchange heat with the outside world through an inlet and outlet 710 provided within the functional cavity 700. In this embodiment, cooling medium 720 can simultaneously generate electricity and utilize thermal energy (for example, to generate hot water). Cooling medium 720 can be tap water or any other environmentally friendly liquid.

[0103] Please refer to FIG2 . In this embodiment, the wasp-waist-shaped solar concentrating unit F and the reflector 400 are enclosed under a transparent top cover 500 , which serves to prevent dust and snow and is also easy to clean.

[0104] Referring to Figure 2 , to achieve better thermal energy utilization, this embodiment preferably includes a thermal function element 600 between the wasp-waisted solar concentrating unit F and the transparent top cover 500. This element is used to insulate the solar concentrating unit F from the transparent top cover 500. Alternatively, the thermal function element 600 may be provided by air. In other embodiments where thermal utilization is not required, the thermal function element 600 serves as a thermal connection between the solar concentrating unit F and the transparent top cover 500.

[0105] This embodiment provides a solar energy utilization device that can generate electricity and utilize heat, which greatly improves the utilization rate of solar energy.

[0106] Example 3:

[0107] Please refer to FIG3 . This embodiment shows a solar energy utilization device. FIG3 shows a vertical cross-sectional schematic diagram of the solar energy utilization device.

[0108] This embodiment uses two wasp-waist-shaped solar concentrating units F stacked one above the other. When the two wasp-waist-shaped solar concentrating units are stacked, there are two light energy utilization units (one is the first light energy utilization unit F100, and the other is the second light energy utilization unit F200) located between the two solar concentrating units F. These two light energy utilization units can be replaced by a double-sided light energy utilization unit. In other embodiments, more solar concentrating units F can be stacked. Stacking increases the height of the solar energy utilization device, thereby making it possible to utilize more sunlight from the sides of the solar energy utilization device. The stacking of multiple wasp-waist-shaped solar concentrating units F can be used to make solar walls and vertical solar energy systems.

[0109] Referring to Figure 3 , this embodiment further includes reflectors 400 on both sides of the two stacked wasp-waisted solar concentrating units F. Unlike the second embodiment, the reflectors 400 in this embodiment are movable components, comprising side reflectors 410 and bottom reflectors 420. The side reflectors 410 and bottom reflectors 420 are movably or detachably connected, allowing the side reflectors 410 to be folded or detached relative to the bottom reflector 420. The use of movable reflectors 400 offers many advantages. First, they can be disassembled for easy portability or transportation; second, the angle of the reflectors 400 can be adjusted according to different application scenarios; and third, they can be configured with control motors and circuits to achieve another form of sun tracking (following the sun) to maximize solar energy utilization.

[0110] Referring to Figure 3 , this embodiment also features a functional cavity 700 beneath the two stacked wasp-waisted solar concentrating units F. Unlike the second embodiment, this embodiment houses a rechargeable battery 730, a control circuit 740, and other electronic devices. This embodiment integrates solar power generation and energy storage with other electronic products (such as security cameras, communication base stations, and automatic watering controls) within the functional cavity 700.

[0111] Example 4:

[0112] Referring to Figure 4 , this embodiment provides a solar energy utilization device similar to that of the third embodiment, but primarily for solar power generation. This solar energy utilization device comprises two stacked, wasp-waist-shaped solar concentrating units F, a reflector 400, and a transparent top cover 500. The concentrating lens F300 comprises a first lens portion F310, a second lens portion F320, and a third lens portion F330. One third lens portion F330 is located at the top of the two stacked wasp-waist-shaped solar concentrating units F, and the other third lens portion F330 is located at the bottom of the two stacked wasp-waist-shaped solar concentrating units F. The third lens portion F330 reduces the need for cleaning the top surfaces of the stacked solar concentrating units F and also improves the light-collecting capability of the side bottom reflector 400. The inverted third lens portion F330 significantly improves the light-collecting capability of the side bottom reflector.

[0113] Referring to FIG4 , in this embodiment, the structure of the third lens unit F330 is identical or similar to that of the first lens unit F310 and the second lens unit F320. The first lens unit F310, the second lens unit F320, and the third lens unit F330 are all made of a transparent liquid, which not only focuses light but also cools the light energy utilization unit. In other embodiments, the first lens unit F310, the second lens unit F320, and the third lens unit F330 may also be made of transparent glass or transparent plastic.

[0114] The difference from the second embodiment is that the reflector 400 and the transparent top cover 500 form a closed cavity, which contains a third lens portion F330.

[0115] Embodiment 5:

[0116] 5 , this embodiment provides a solar energy utilization device similar to the fourth embodiment, but with a greater concentration ratio. The solar energy utilization device includes two stacked wasp-waist solar energy concentrating units F, a reflector 400 and a transparent top cover 500 .

[0117] There are four main differences between this embodiment and the fourth embodiment: First, in this embodiment, a third lens portion F330 is provided on the top of the two stacked wasp-waist solar concentrating units F, but no third lens portion F330 is provided on the bottom. In contrast, a transparent liquid 900 is provided in the concentrating cavity 510 composed of the transparent top cover 500 and the reflector 400. The transparent liquid 900 not only increases the concentration ratio but also cools the wasp-waist solar concentrating units F; second, the reflector 400 includes a side reflector 410 and a bottom reflector 420, wherein the side reflectors 410 are provided on the transparent top cover 500 and on both sides of the solar concentrating units F, and the bottom reflector 420 is provided between the transparent top cover 500 and the wasp-waist solar concentrating units F. Thirdly, the bottom reflector 420 of the reflector 400 is significantly different from the reflector 400 in the fourth embodiment in terms of structure and morphology. This is because in the present embodiment, the light-collecting cavity 510 is filled with transparent liquid 900, while in the fourth embodiment, only the third lens portion F330 in the light-collecting cavity is filled with transparent liquid 900. This difference determines that the middle part of the bottom reflector 420 of the reflector 400 in the present embodiment requires a convex structure to achieve a good light-collecting effect.

[0118] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art can make several simple deductions, modifications or substitutions based on the concept of the present invention.
