Light guiding solar panel device

The invention relates to a solar panel device, in particular to a light guiding solar panel device.

In order to enhance the green energy, the existing greenhouses will be equipped with solar panels on the roof to save energy. However, since the solar panels are not transparent, the sunlight needed to avoid plant growth is completely blocked. In the installation, it will be in the greenhouse. The roof is partially installed with solar panels, and the other part is not installed. However, this will lead to uneven illumination, which causes plants in some areas to be exposed to excessive sunlight, while other parts of the plants are not able to obtain sufficient sunshine. Plant growth, on the other hand, when there are multiple greenhouses and solar panels are placed on the roof of each greenhouse, how to let the sunlight evenly pass through the distance between the adjacent greenhouses is also the current study. The goal of development.

Accordingly, it is an object of the present invention to provide a light-conducting solar panel apparatus that solves the above problems.

Therefore, the light guiding solar panel device of the present invention comprises at least two solar panels and a light guide panel module.

The solar panels are spaced apart from each other by a gap through which light can pass.

The light guide plate module comprises a light guide plate with a light transmissive material, and the light guide plate is disposed under the solar energy plates corresponding to the gap, and the light that guides the penetration is evenly distributed.

The effect of the present invention is that by providing the light guide plate corresponding to the gap, the light guided by the gap can be guided to uniformly distribute the light by the light guiding property of the light guide plate, thereby guiding The sunlight reaches all corners of the greenhouse, making the illumination uniform, which not only can effectively improve the utilization of the light source, but also help the plants in the greenhouse to grow.

Referring to FIG. 1 and FIG. 2, an embodiment of a light guiding solar panel device of the present invention comprises two solar panels 2, a light guide panel module 3, two illumination modules 4, and two mirror modules 5 .

The solar panels 2 are spaced apart from each other by a gap 9 for light to penetrate, and the number thereof may be determined according to actual needs. The minimum number may be two as shown in FIG. 2, but it may also be as shown in FIG. According to the actual demand, the number is expanded up and down, and is not limited to this.

Referring to FIG. 1 and FIG. 2 , the light guide plate module 3 includes a light guide plate 31 and a receiving space 32 .

The light guide plate 31 is disposed under the solar panels 2 corresponding to the gap 9, and guides the light transmitted by the gap 9 to be evenly distributed by the light guiding property of the light guide plate 31, and the light guide plate 31 forms an opening toward the opening. The recess 33 of the solar panel 2 is defined to define the accommodating space 32.

Wherein, the light guide plate 31 faces the surface of the gap 9 as a non-smooth surface, and the surface may form a zigzag pattern as shown in FIG. 1, or may form a wavy line as shown in FIG. The combination of the two lines of demand is not limited to this.

The material of the light guide plate 31 is one of plastic and glass, and the plastic material can be selected from acrylic (polymethylmethacrylate, polymethylmethacrylate, PMMA, English Acrylic), polycarbonate (Polycarbonate, PC for short). one of them.

Referring to FIG. 1 and FIG. 2 , the accommodating space 32 is located between the light guide plate 31 and the gap 9 and the solar panels 2 for accommodating liquid.

The illumination modules 4 are respectively disposed between the mirror modules 5 and the light guide panel module 3, wherein the number of the illumination modules 4 can be determined according to actual needs, if the illumination illumination needs are low. In the case of plants, a smaller number of illumination modules 4 may be provided, or even a group of illumination modules 4 may be provided, or the illumination module 4 may not be disposed as shown in FIG. 5, and the illumination directions of the illumination modules 4 are It can also be adjusted according to actual needs. Generally, the previous irradiation is the preset direction, but the direction can be adjusted according to the needs of the plants grown in each area.

The mirror modules 5 are respectively disposed between the solar panels 2 and the illumination modules 4, and have a mirror surface facing downward.

Through the above description, the advantages of this embodiment can be summarized as follows:

1. By arranging the light guide plate 31 corresponding to the gap 9, the light guiding property of the light guide plate 31 can be guided to uniformly distribute the light by the light guiding property of the light guide plate 31 as shown in FIG. Therefore, it can guide the sunlight to all corners of the greenhouse, so that the illumination is uniform, which not only can effectively improve the utilization of the light source, but also help the plants in the greenhouse to grow. Even if there are multiple greenhouses, it can directly cross the adjacent areas. Above the greenhouse, the sunlight can be evenly transmitted from the distance between the adjacent greenhouses to the greenhouse.

2. By arranging the accommodating space 32 to accommodate a liquid (preferably water), the uniformity of the light distribution can be improved without significantly increasing the cost by the refracting light guiding property of the liquid.

Furthermore, the groove 33 is formed by designing the light guide plate 31 to define the accommodating space 32, and the goal of increasing the uniformity of light distribution can be achieved without additional components.

3. By providing the illumination module 4, it is possible to increase the luminosity when the sunlight is insufficient or in the area where the light is less than the illumination, thereby depending on the climatic conditions or the sunshine intensity required by different plants. Adjustments can be made to increase the flexibility of use.

4. The mirror module 5 is disposed between the solar panel 2 and the light guide panel module 3, so that the light reflected by the liquid in the light guide plate 31 or the accommodating space 32 can be reflected downward again. Thereby, not only can the utilization of light be increased, but also the uniformity of light distribution can be improved again.

5. By designing the light guide plate 31 toward the surface of the gap 9 as a non-smooth surface, the light can be reflected upward by the light guide plate 31 at various angles, and then reflected downward by the mirror module 5. In this way, the effect of uniform light distribution can be improved.

In summary, the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
