Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. For example, based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to FIG. 1 and FIG. 2, a solar lamp includes a lamp body, a monocrystalline silicon solar panel 2 or a polycrystalline silicon solar panel 3, and an amorphous silicon solar panel 4; a monocrystalline silicon solar panel 2 or a polycrystalline silicon solar panel 3 and the lamp The body is electrically connected to supply power to the lamp body; the amorphous silicon solar panel 4 is electrically connected to the lamp body to supply power to the lamp body, because in most cities in China, the number of sunny days is more than the number of rainy days. , so the illumination area of the monocrystalline silicon solar panel 2 or the polycrystalline silicon solar panel 3 is larger than the illumination area of the amorphous silicon solar panel 4 . The photoelectric conversion efficiency of monocrystalline silicon solar panel 2 is about 15%, and the highest is 24%, which is the highest photoelectric conversion efficiency of all types of solar panels. The solar panel 2 is cheaper, the material is simple to manufacture, the power consumption is saved, and the total production cost is lower, but the photoelectric conversion efficiency is lower than that of the monocrystalline silicon solar panel 2. The photoelectric conversion efficiency is high in the environment, and the amorphous silicon solar panel 4 can also generate electricity in cloudy and rainy days, that is, in a weak light environment.

The lamp body includes a casing 12 and a first LED lamp panel 11 , the casing 12 is in the shape of a triangular prism, and the first LED lamp panel 11 is disposed on the first parallelogram side surface 121 of the casing 12 .
