LED solar street lamp

Abstract

The invention discloses an LED solar street lamp. The LED solar street lamp comprises a pole body, a solar cell assembly arranged on the top of the pole body and a lamp body arranged on a lamp pole; abase is connected to the bottom end of the pole body, a storage cell and a control device are arranged in the base, the storage cell and the lamp body are electrically connected, the lamp body comprises a light condensing lampshade, a foundation base and multiple LED lamp beads arranged on the upper surface of the foundation base, cooling fins are arranged on the lower portion of the foundation base, and the solar cell assembly comprises a solar cell panel and a mounting frame arranged on the periphery of the solar cell panel. The solar cell panel is sequentially provided with a protection layer, a tempered glass layer, a reflection layer, a cell panel, a base body layer and a weather-resisting layer from front to interior, wherein the protection layer, the tempered glass layer, the reflection layer, the cell panel, the base body layer and the weather-resisting layer are connected through a glue sticking layer, the surface, making contact with the protection layer, of the tempered glass layer is provided with a first protruding part and a second protruding part, and multiple prism protruding parts are arranged on the surface of the reflection layer. Through the prism protruding parts on the surface of the reflection layer, the light reflection use rate is improved.

Description

technical field [0001] The invention relates to the technical field of street lamps, in particular to an LED solar street lamp. Background technique [0002] In today's urban lighting and road lighting, the proportion of street lighting is increasing, and the contradiction with the existing power supply is becoming more and more prominent. Therefore, it is an inevitable trend to replace traditional street lights with solar street lights. Solar energy is especially favored as a green energy. Solar photovoltaic power generation is an important way to utilize solar energy. Solar photovoltaic power generation directly converts visible light in the solar spectrum into electrical energy. The existing solar panel chip layer is mainly composed of sealed solar chips. Thin-film solar chips are silicon wafers sealed with EVA and TPT. When light irradiates on the surface of flat glass, a large amount of light will scatter, reducing the concentration effect per unit area and resulting in...

Solar energy is especially favored as a green energy. Solar photovoltaic power generation is an important way to utilize solar energy. Solar photovoltaic power generation directly converts visible light in the solar spectrum into electrical energy. The existing solar panel chip layer is mainly composed of sealed solar chips. Thin-film solar chips are silicon wafers sealed with EVA and TPT. When light is irradiated on the surface of flat glass, a large amount of light will be scattered, which will reduce the concentration effect per unit area and result in low photoelectric conversion efficiency.
