Solar street lamp

Abstract

The invention discloses a solar street lamp which comprises a lamp post, a solar cell panel supporting rod, a solar cell panel, a street lamp supporting rod, a street lamp mounting base and a street lamp body. A solar cell panel supporting rod and a street lamp supporting rod are arranged on the left and right sides of the upper end of the lamp post correspondingly. The outer sides of the solar cell panel supporting rod and the street lamp supporting rod are respectively provided with a solar cell panel and a street lamp supporting rod which are vertical to the sunlight when the sun just rises; street lamp installation bases are fixed to the outer sides of the street lamp supporting rods. A street lamp for illumination is arranged at the bottom of the street lamp mounting base; and the solar street lamp further comprises a deflection mechanism which is used for driving the solar cell panel to rotate along with the rising direction of the sun. According to the solar street lamp, by arranging the deflection mechanism, the solar cell panel can be kept approximately perpendicular to solar illumination continuously, and therefore the illumination conversion efficiency is improved; by arranging the lifting mechanism, the heights of the street lamp and the solar cell panel can be conveniently adjusted, and therefore maintenance and cleaning are convenient.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a solar street lamp. Background technique [0002] With the development of urban construction, a large number of lights have also been installed on both sides of urban roads. As a green and environmentally friendly new energy source, solar energy has been applied in more and more fields. On both sides of urban roads, solar street lights have gradually replaced traditional street lights, which can save energy. [0003] Solar street lights, the solar panels on the surface absorb light energy during the day and convert it into electrical energy, and the stored electricity is used to supply lighting for lighting at night. However, in the existing solar street lamps, the solar panels of the solar panels are fixed when they absorb the sun's light, so that when the sun rises and falls, the light and the solar panels will form a certain deflection angle, thereby causing the solar pane...
