Environment-friendly LED street lamp

Abstract

The invention discloses an environment-friendly LED street lamp. The environment-friendly LED street lamp comprises a stand column, a first supporting arm and a second supporting arm which are fixedly arranged above the two sides of the stand column, an LED lamp holder is arranged at the bottom of the first supporting arm, a photovoltaic panel protection shell is arranged on the top of the second supporting arm, a containing cavity is formed in the photovoltaic panel protection shell, guide 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 guide sliding grooves, a lifting sliding block is arranged in the containing cavity, the two side ends of the lifting sliding blocks are embedded in the guide sliding grooves and are in sliding fit connection with the guide sliding grooves, a lifting push device is arranged at the bottom of the lifting sliding block, a drive cavity is formed in the lifting sliding block, a guide sliding groove is formed in the middle of the bottom of the drive cavity, guide sliding cavities are arranged in the lifting sliding block of the top of the drive cavity in a bilateral symmetry manner, sleeves are arranged in the guide sliding cavities, and the sleeves are arranged in a vertical extending manner along the guide sliding cavities. The environment-friendly LED street lamp is simple in structure, stable in structure and convenient to operate, the multi-angle adjustment is achieved, the protection function is achieved, and photovoltaic panel damage caused by climatic factor influences is avoided.

Description

technical field [0001] The invention relates to the technical field of street lamps, in particular to an environment-friendly 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 pan...

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
