Description

A solar street lamp

technical field

The utility model relates to a street lamp, more specifically a solar street lamp.

Background technique

In the prior art, the structural form of solar street lights is to use crystalline silicon solar power generation panels, and the solar power generation panels are installed on the upper end of the lamp pole. This form mainly has the following disadvantages:

1. The crystalline silicon solar power generation panel is made of laminated toughened glass, back film and back plate, and is surrounded by an aluminum alloy frame. A conventional 80-watt solar power generation panel weighs about 8 kg, so such a power generation panel Installed on the upper end of the light pole, the wind resistance of the light pole is high, and the strength of the light pole is high, which not only makes the cost of the light pole higher than that of ordinary light poles, but also makes the light poles higher when the light poles are higher. , security is also tested.

2. The low-light performance of crystalline silicon solar panels is not good. Therefore, this type of lamps has high requirements for the use environment. Only places where sunlight is directly irradiated can generate electricity. It is required that there should be no tree shade or other shades around when installing. objects, the solar panels should be installed facing south.

3. The high temperature resistance of crystalline silicon solar panels is poor, and the high ambient temperature will affect the power generation performance.

4. The cost of crystalline silicon solar power generation panels is relatively high, and the main cost component of solar street lamps is solar cells, so the cost of solar lamps produced with crystalline silicon solar cells is higher than that of amorphous silicon solar cells.

Utility model content

The utility model aims at avoiding the disadvantages of the above-mentioned prior art, and provides a solar street lamp with low cost, good low-light performance, good high-temperature performance and easy implementation.

The utility model solves the technical problem and adopts the following technical solutions:

The solar street lamp of the utility model includes setting a light pole, and the lamp head is supported by a cantilever arm at the top of the light pole;

The structural feature of the utility model is that flexible amorphous silicon thin film solar cells are used, and the flexible amorphous silicon thin film solar cells are coated on the surface of the pole body of the light pole. Power is supplied by a DC light source in the lamp head.

Structural features of the present utility model also are:

The flexible amorphous silicon thin-film solar cell is spirally wound and pasted and fixed on the surface of the light pole.

The solar controller is arranged inside the light pole body and at the bottom of the light pole body.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

1. The utility model uses flexible amorphous silicon thin-film solar cells. Due to the flexible structure, it can be directly coated on the surface of the light pole body. Therefore, the wind resistance of the light pole is the same as that of ordinary lamps, and the cost of the light pole is not increased.

2. In this utility model, since the flexible amorphous silicon thin-film solar cell has better weak light performance, regardless of the strength of the sunlight around the solar lamps and lanterns, facing the sunlight or facing away from the sunlight, the flexible amorphous silicon thin film on the surface of the lamp pole will Solar cells have no major impact, have low requirements on the use environment, and are easy to implement.

3. In the utility model, since the flexible amorphous silicon thin-film solar cell has better high-temperature performance, the power generation will not be affected even in the case of high temperature in summer.

4. In the present invention, the cost of the flexible amorphous silicon thin-film solar cell is relatively low, so that the cost of solar lamps is lower than that of crystalline silicon solar cells.
