Solar street lamp with hot spot prevention effect for lighting engineering

Abstract

The invention relates to a solar street lamp with a hot spot prevention effect for lighting engineering. The street lamp comprises a base, a lamp post, an illuminating lamp and a photoelectric device;the photoelectric device comprises a top plate, an adjusting mechanism, an adjusting plate and a photoelectric mechanism; the adjusting mechanism comprises a lifting assembly, a lifting plate and anadjusting assembly. The adjusting assembly comprises an annular groove, a sliding block, a first motor, a rolling wheel and a second motor. The photoelectric mechanism comprises a driving assembly andtwo photoelectric assemblies; the photoelectric assembly comprises a gear, a rotating shaft, a photovoltaic panel, two supporting pipes and two connecting frames. According to the solar street lamp capable of preventing the hot spot effect for the lighting engineering, the position of the adjusting plate is conveniently driven through the adjusting mechanism, so damage caused by contact between photovoltaic panel and a shielding object when the photovoltaic panel moves upwards is avoided; in addition, the angle of the photovoltaic panel can be flexibly adjusted through the photoelectric mechanism, the photovoltaic panel is rotated to the vertical angle to reduce contact with the shielding object when the photovoltaic panel rises, the photovoltaic panel is rotated to the horizontal angle after being adjusted, photovoltaic power generation is facilitated, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of lighting engineering, in particular to a solar street lamp for preventing hot spot effect in lighting engineering. Background technique [0002] As a kind of traffic lighting facility, solar street light works on a very simple principle. It is a solar panel made of the principle of photovoltaic effect. During the day, the solar panel receives solar radiation and converts it into electrical energy, which is stored in In the battery, when the illuminance gradually decreases to the set value at night, the open circuit voltage of the solar panel changes to a certain extent, the charging and discharging controller automatically detects this voltage and then sends out a braking command, and the battery starts to discharge the lamp head. After the battery is discharged for about 8.5 hours, the charging and discharging controller sends out a braking command, and the battery discharge ends. [0003] With the development of...

Problems solved by technology

[0003] With the development of power systems and greening projects, a large number of power cables have been built in cities for power transmission and power supply. At the same time, a large number of trees have been planted on both sides of the road for greening the environment and beautifying the city. Most of the branches and leaves are located at high places. As the time of day changes, these cables and branches and leaves are easy to block sunlight, leaving shadows everywhere on the solar panel, affecting the amount of sunlight received by the solar panel, reducing power generation efficiency, and causing heat. Spot effect, causing damage to solar panels, which in turn reduces the practicability of existing solar street lights
