Detailed Description
The technical scheme of the invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a lighting device for a solar panel according to an embodiment of the present invention includes a lighting unit. The lighting unit comprises a lighting shade 1, a light pipe 2, an elbow pipe 3, a light transmission conduit 4 with a light emitting surface 41, a first reflecting piece 5 and a second reflecting piece 6. One end of the light pipe 2 is connected with a light outlet of the daylighting shade 1, the other end of the light pipe 2 is connected with one end of the bent pipe 3, and the other end of the bent pipe 3 is connected with one end of the light transmission conduit 4. The first reflector 5 is used to reflect light from the light pipe 2 into the light transmission conduit 4. The second reflecting element 6 is used for reflecting the light to the light emitting surface 41 of the light transmission conduit 4.
In the above embodiment, the lighting cover 1 in the lighting unit is used for collecting external sunlight. Sunlight collected by the lighting cover 1 enters the light guide tube 2. The light is transmitted into the bent pipe 3 through multiple reflections in the light pipe 2, and the light changes the transmission path through the reflection of the first reflecting piece 5 and enters the light transmission conduit 4. In the light transmission tube 4, a part of the light is directly emitted from the light transmission tube 4 to the light emitting surface 41, and a part of the light is reflected by the second reflecting member 6 to be emitted from the light emitting surface 41. If the light emitting surface 41 of the light transmission duct 4 is opposed to the rear surface of the solar cell panel, the collected sunlight is irradiated to the rear surface of the solar cell panel through the lighting unit, thereby increasing the power generation efficiency of the solar cell panel.
As a preferable example, the lighting cover 1 is hollow and is provided with a light outlet; the lighting cover 1 is made of transparent materials. The light outlet of the lighting cover 1 is connected with the light pipe 2. The lighting cover 1 may be a hollow hemisphere, or may have a surface formed by a plurality of polygons. The lighting cover 1 is mainly used for collecting more external solar rays, and the size of the lighting cover can be set according to the area of the solar cell panel to be irradiated.
As a preferred example, the inner wall of the light pipe 2 is provided with a first mirror layer. By arranging the first mirror layer, the absorption of light by the light pipe 2 is reduced, the light reflection is increased, and the light reflection and transmission efficiency are improved. When the light is transmitted to the inner wall of the light pipe 2, the light is reflected and transmitted downwards under the action of the first mirror surface layer.
As a preferred example, as shown in fig. 2, the light pipe 2 has a hollow cylindrical shape. The light pipe 2 is connected with the lighting cover 1. The light pipe 2 is arranged in a hollow cylinder shape, so that the light pipe is convenient to be matched with the lighting cover 1.
As a preferred example, the inner wall of the bent pipe 3 is provided with a second mirror layer. As shown in fig. 3, the elbow 3 may be provided as a 90 degree elbow. The diameter of the bent pipe 3 is larger than that of the light pipe 2. By arranging the second mirror layer, the absorption of the bent pipe 3 to light is reduced, the light reflection is increased, and the light reflection and transmission efficiency are improved. When the light is transmitted to the inner wall of the bent pipe 3, the light is reflected under the action of the second mirror surface layer, and the propagation path is changed. The transmission direction of the light is changed by arranging the bent pipe 3. The invention is mainly used for irradiating the back surface of the solar panel. The sunlight is difficult to irradiate on the back surface of the solar cell panel, so that the collected sunlight needs to change the transmission path to be transmitted to the back surface of the solar cell panel.
As a preferred example, the first reflecting member 5 is a reflecting mirror surface, and is located at a corner of the inner cavity of the elbow pipe 3, the first reflecting member 5 is connected with the elbow pipe 3, and the first reflecting member 5 is an outer convex arc surface, an inner concave arc surface or an inclined plane. The first reflecting member 5 reflects the light transmitted from the light guide 2 into the light transmission duct 4. If the bent pipe 3 is 90 degrees, the bent pipe 3 and the first reflecting piece 5 positioned in the bent pipe 3 realize that the light rays are transmitted from the whole vertical direction to the whole transverse direction.
As a preferable example, as shown in fig. 4 and 5, the second reflecting member 6 is a reflecting mirror surface and is located in the light transmission duct 4, the second reflecting member 6 is connected to the light transmission duct 4, and the second reflecting member 6 is opposite to the light emitting surface of the light transmission duct 4. The second reflecting element 6 reflects the light transmitted to the surface thereof directly or indirectly to the light emitting surface 41 of the light transmitting tube 4. By providing the second reflecting member 6, the light in the light transmission conduit 4 can be faster and more can be directed to the light emitting surface 41 of the light transmission conduit 4. The solar cell panel is irradiated to the back surface of the solar cell panel by the divergence of the light-emitting surface 41, so that the irradiation amount and the sunlight intensity of sunlight are improved, the photoelectric conversion rate is improved, and the generated energy is increased.
As a preferred example, the second reflecting element 6 is arranged axially along the light transmission conduit 4. Since light enters the light transmission tube 4 from one end of the light transmission tube 4, the second reflecting member 6 is disposed along the axial direction of the light transmission tube 4, so that more light is reflected by the second reflecting member 6 toward the light emitting surface 41. Preferably, the length of the second reflecting member 6 is equal to the length of the light transmission conduit 4.
As a preferred example, the second reflecting member 6 is a convex arc surface or a concave arc surface. The second reflecting member 6 is an arc-shaped specular reflecting surface, and can reflect light to the light emitting surface for irradiation.
In the light transmission conduit 4, a third mirror layer is disposed on the inner wall between the second reflecting member 6 and the light emitting surface 41. As shown in fig. 4 and 5, the light transmission conduit 4 may be a hollow semicircular cylinder. One surface of the light transmission conduit 4 is provided as a plane or arc-shaped transparent glass panel, and serves as a light emergent surface. The light-emitting surface 41 may be a whole plane or a part of the whole plane. For example, as shown in fig. 7, a rectangular point light source, or a circular point light source may be a long linear light source having a certain width. As shown in fig. 8, the light-emitting surface 41 is an arc-shaped transparent glass panel. Light entering the light transmission tube 4 from one end of the light transmission tube 4 is partially directly incident on the inner wall between the second reflecting member 6 and the light exit surface 41. Therefore, the third mirror layer is disposed on the inner wall between the second reflecting element 6 and the light-emitting surface 41, so that the light can be reflected, and the light is prevented from being absorbed by the light-transmitting tube 4 or being refracted out of the light-transmitting tube 4, thereby improving the light utilization rate.
In the lighting unit, the lighting cover 1 is one, one end of the light transmission conduit 4 connected with the bent pipe 3 is an opening, and the other end is a closed inclined plane. The lighting unit with the structure is provided with a lighting cover 1, a light transmission conduit 4, an elbow pipe 3 and a light pipe 2. The light collecting cover 1 collects external light, the light enters the bent pipe 3 through the light pipe 2, and enters the light transmission conduit 4 after changing the transmission direction, and finally is emitted from the light emitting surface 41 of the light transmission conduit 4. If the transmission direction of a part of the light entering the light transmission conduit 4 is parallel to the axis of the light transmission conduit 4, the part of the light is directly or indirectly reflected to the light exit surface 41 when the part of the light is transmitted to the other end surface of the light transmission conduit 4 because the end surface is an inclined surface.
As a preferable example, as shown in fig. 6, in the lighting unit, two lighting covers 1, light pipes 2 and bent pipes 3 are provided, and one light transmission conduit 4 is provided; one lighting cover 1, one light pipe 2 and one bent pipe 3 are positioned at one end of the light transmission conduit 4, and the other lighting cover 1, the other light pipe 2 and the other bent pipe 3 are positioned at the other end of the light transmission conduit 4; both ends of the light transmission conduit 4 are through holes.

Thus, the external light collected by the two light-collecting covers 1 finally enters the same light-transmitting duct 4 and is emitted from the light-emitting surface 41 of the light-transmitting duct 4. Compared with the lighting unit with the former structure, the lighting unit with the structure of the preferred embodiment collects twice of external light and greatly improves the power generation effect of the solar panel.
As a preferable example, the light emitting surface 41 is a spaced light source, or a strip-shaped non-spaced light source. Square or rectangular interval light sources having different lengths may be provided on the light emitting surface 41. Or circular spaced light sources of unequal diameters. It can also be arranged as a strip of non-spaced light sources. By arranging the interval type light sources or the strip-shaped non-interval type light sources, the solar radiation amount can be increased, and the generated energy can be increased.
As a preferred example, the solar panel further includes optical fibers, where the optical fibers are located in the light collecting cover 1, the light pipe 2, the elbow pipe 3 and the light transmission conduit 4. The optical fibers are fixedly connected with the lighting cover 1, the light pipe 2, the bent pipe 3 and the light transmission conduit 4 respectively. By arranging the optical fiber, the light collection amount and the light transmission capacity are increased, the solar radiation amount is improved, and the generated energy is increased.

The light collection cover 1 may be located at the side, above or below the panel body 7. The sun can directly irradiate the lighting cover 1. The light-emitting surface 41 of the light transmission duct 4 faces the back surface of the panel body 7. Like this, the solar ray that light collecting cover 1 gathered, through light pipe 2, return bend 3, first reflector 5, light transmission pipe 4 and second reflector 6, the outgoing light face 41 is followed, shines the back at panel body 7 for panel body 7 back has also realized generating electricity, and the generating efficiency is higher.

The light transmission duct 4 of each lighting unit is opposite to a row or column of panels. Thus, the light emitted from the light emitting surface 41 of the light transmitting tube 4 of one lighting unit is irradiated to one row of panels or one column of panels correspondingly.
