Solar LED streetlamp

Abstract

The invention discloses a solar LED streetlamp. The solar LED streetlamp comprises a stand column, a first supporting arm and a second supporting arm, wherein the first supporting arm and the second supporting arm are fixedly arranged at the upper portions of the two sides of the stand column. An LED lamp holder is arranged at the bottom of the first supporting arm. A photovoltaic plate protection shell is arranged on the top of the second supporting arm and internally provided with a containing cavity. Guiding sliding grooves are formed in the inner walls of the two sides of the containing cavity. Limiting blocks are arranged at the upper side ends of the guiding sliding grooves. A lifting sliding block is arranged in the containing cavity. The two side ends of the lifting sliding block are embedded in the guiding sliding grooves and are connected with the guiding sliding grooves in a sliding fit manner. A lifting pushing device is arranged at the bottom of the lifting sliding block. A drive cavity is formed in the lifting sliding block. A guiding sliding groove is formed in the middle position of the bottom of the drive cavity. Guiding sliding cavities are formed in the lifting sliding block on the top of the drive cavity in a left-right symmetry manner and internally provided with sleeves extending up and down along the guiding sliding cavities. The solar LED streetlamp is simple in structure, stable in structure and convenient to operate; and multi-angle adjustment can be conducted, a protection function is achieved, and photovoltaic plate damage caused by the influence from the climatic factor is avoided.

Description

technical field [0001] The invention relates to the technical field of street lamps, in particular to a solar-powered LED street lamp. Background technique [0002] Solar street lights use sunlight as energy, solar panels charge the battery during the day, and the battery supplies power to the light source at night, without complicated and expensive pipeline laying, the layout of the lamps can be adjusted arbitrarily, safe, energy-saving and pollution-free, stable and reliable without manual operation, saving Electricity is maintenance-free. At present, the solar street lamps on the market, the solar panel grooves are fixed in one direction. Generally, the solar panels are grooved in the south direction, and the inclination angle of the solar panels is 30-45 degrees. In fact, due to the rotation of the earth, the direction of the sun relative to the ground is constantly changing throughout the day. However, in such solar street lamps in the prior art, the solar panel is fi...

AI Technical Summary

Problems solved by technology

However, such solar street lamps in the prior art fix the solar panel to the south to fix the groove, so sufficient lighting effects cannot be obtained, so photoelectric conversion cannot be fully performed, resulting in low conversion utilization of solar energy

[0003] However, the solar panel has a large surface area and a complex structure, which is easily affected by climatic factors such as wind and dust, and is extremely prone to damage under some extreme conditions

This caused economic loss and affected the normal traffic of the road
