Energy-saving LED solar street lamp

Abstract

The invention discloses an energy-saving LED solar street lamp. The energy-saving 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; a base is connected to the bottom end of the pole body, a storage cell is arranged in the base, the storage cell is electrically connected with the lamp body, the lamp bodycomprises a light condensation lampshade, a foundation base and multiple LED lamp beads arranged on the upper surface of the foundation base, and cooling fins are arranged on the lower portion of thefoundation base. The solar cell assembly comprises a solar cell panel and a mounting frame arranged on the periphery of the solar cell panel, and a light sensitive resistor for controlling the lamp body to be on or off is arranged on the top of the lamp body and comprises an upper electrode layer, a lower electrode layer and a middle light sensitive material. According to the energy-saving LED solar street lamp, multiple prism protruding parts are arranged on the surface of the reflection layer of the solar cell panel, repeated absorbing can be formed, the reflecting property of the solar cellpanel can be improved, through the light sensitive circuit, the street lamp can automatically induce the existence of visible light, the streetlamp can be automatically turned on and off, and the lamp is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of street lamps, in particular to an energy-saving 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. The solar panel chip layer in the existing solar street lamps is mainly composed of sealed solar chips. The sealed solar chips are silicon wafers sealed with EVA and TPT. When the light is irradiated on the surface of the flat glass, a large amount of light will be scattered. phenomenon, which reduces the concentrating effect per unit area, resulting in low photoelectric conversion efficiency; in addition, the existing solar street lamps are artificially programmed, that is, when the on time and off time are set, the street lam...

Problems solved by technology

The solar panel chip layer in the existing solar street lamps is mainly composed of sealed solar chips. The sealed solar chips are silicon wafers sealed with EVA and TPT. When the light is irradiated on the surface of the flat glass, a large amount of light will be scattered. phenomenon, which reduces the concentrating effect per unit area, resulting in low photoelectric conversion efficiency; in addition, the existing solar street lamps are artificially programmed, that is, when the on time and off time are set, the street lamps will be fixed accordingly. It can be turned on or off at any time, but this method has disadvantages, that is, in the summer with a long sunshine time, it is easy to appear that the sky is not dark, but the street lights are already on. dark, and the street lights are not on

This situation will lead to a large waste of electric energy, and further, it is not conducive to energy saving and environmental protection.
