Solar street light

This creation is about a solar street light, especially a solar street light that can cover a light pole to increase power generation.

The existing solar power generation device for providing power, for example, solar circuit lights installed on both sides of the road, is to fix the solar panel above the lamp cover or additionally install a solar panel from the lamp pole to absorb sunlight for conversion of electric energy. However, the existing solar power generation device has a limited light absorption area and the angle at which sunlight is collected is limited, and the power generation amount cannot be effectively increased. In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

One of the purposes of this creation is to provide a solar street light that increases the orientation, angle and area of sunlight to increase power generation.

To achieve the above objectives, the present invention provides a solar street lamp comprising a lampshade and a plurality of solar modules. A light source is disposed in the lampshade, and one end of the lamp cover is connected to a light pole. Each solar module includes a frame, a solar cell array disposed on an outer side of the frame, a first pivoting portion disposed on one side of the frame, and a second pivoting member on the other side of the frame. And the first pivoting portion is pivotally connected to the second pivoting portion of the corresponding solar module to cover the lamp post in a closed manner.

The creation also has the following effects: each solar module can extend the length of each solar cell array and the closed covered light pole by the length of the light pole. The solar modules of the present invention can effectively absorb sunlight and convert into electric energy regardless of the orientation or angle of sunlight, thereby increasing the amount of power generation. In addition, each solar module has a simple structure, is easy to install, and has low cost, so that the power generation amount can be easily increased, and the electric energy of the illuminating light source can be provided.

In addition, each solar module 130 can extend the length of each of the solar cell arrays 150 (and the frame 140) and close the covered light poles 120 by the length of the upright light poles 120. The first pivoting portion 160 is connected in parallel with the second pivoting portion 170 of the adjacent solar module 130, and is respectively a hinge assembled to each other. The number of the first pivoting portion 160 and the second pivoting portion 170 is preferably two, as shown in FIG. 1; however, in other different embodiments, the first pivoting portion 160 and the second pivoting portion 170 are respectively provided. The number of the frames 140 may also be increased depending on the length of the frame 140, and is not limited.

As shown in FIG. 2 , in order to facilitate the fixing of each solar module 130 , a first positioning plate 122 and a second positioning plate 124 opposite to the first positioning plate 122 are further included. Each of the solar modules 130 is sandwiched by the first positioning plate 122 and the second positioning plate 124 on the light pole 120. In the embodiment shown in FIG. 2 , the first positioning plate 122 and the second positioning plate 124 are respectively provided with a through hole 126 penetrating the light pole 120 and a flat plate 128 abutting each solar module 130 . The aperture of the through hole 126 can be less than or equal to the outer diameter of the lamp post 120 and is fixed to the lamp post 120 in a tight fit manner.

The number of the solar modules 130 in this embodiment is preferably four to cover the lamp post 120 to form a rectangular cylinder. In other different embodiments, the number of the solar modules 130 may also be three, to cover the light pole 120 to be a triangular cylinder, or other cylinders, such as a polygonal cylinder, etc., as needed. change. When the solar modules 130 are covered by the rectangular cylinder, the triangular cylinder or other polygonal cylinders, the flat plates 128 of the first positioning plate 122 and the second positioning plate 124 are correspondingly designed as a rectangular plate, a triangular plate or Other polygonal plates and the like can prevent rain or dust from penetrating into the solar modules 130, causing corrosion or damage to internal components.

The embodiment shown in FIG. 2 further includes a battery 190 and a control unit 200. The control unit 190 can control the amount of power that each solar array 150 converts and stores in the battery 200. That is to say, the control unit 190 has functions such as charging control, charging protection, discharge protection, overload protection, short circuit protection, etc., since it is a prior art, it will not be described here. The positions of the battery 190 and the control unit 200 as shown in the figure may be disposed on the base (not shown) of the lamp post 120 through wires (not shown) or other suitable places, and may be changed as needed, and are not limited.

Further, the control unit 200 can programmatically control the converted electrical energy of the solar array 150 of each solar module 130 and store it in the battery 200, and then provide the electrical energy of the battery 200 to the illuminating source 110 for illumination. Therefore, the solar modules 130 of the enclosed light pole 120 of the present invention can increase the azimuth, angle and area of the sunlight in a timely manner, regardless of the change of the orientation or angle of the sun, to increase the power generation and provide illumination. Light source 110 or other sign is used.

In addition, each of the solar modules 130 has a simple structure, is easy to pivot/mount the light poles 120, and is low in cost, so that the power generation amount can be easily increased, and the power of the light source 110 can be provided.
