Solar streetlamp with adjustment function applied to urban lighting

Abstract

The invention relates to a solar streetlamp with an adjustment function applied to urban lighting. The solar streetlamp comprises a pedestal, a lamp post, a photovoltaic panel, a cross plate, a processor, a lighting mechanism and a cooling mechanism, wherein the lighting mechanism comprises a lamp shell, a substrate, two partitions and a plurality of lighting components; each lighting component comprises a telescopic unit, a reflector, lamp tubes, a power supply and two contact units; and the cooling mechanism comprises a cooling tube, a heat conduction rod, two suspension rods and two vent pipes. When the solar streetlamp with the adjustment function applied to urban lighting is running, the lighting mechanism can adjust the quantity of galvanical lamp tubes according to the brightness ofan external environment, so that illuminating brightness is ensured on the basis of saving electric energy; furthermore, air flows circularly in the lamp shell and the cooling tube via the cooling mechanism, heat is transferred to the heat conduction rod, upper fins and lower fins after being absorbed by the air, the heat is convenient to dissipate to the outside, cooling of the environment in the lamp shell is achieved, service life of the equipment is prolonged and practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of solar street lamps, in particular to a solar street lamp with adjustment function for urban lighting. 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] When the existing solar street lamps...

AI Technical Summary

Problems solved by technology

[0003] When the existing solar street lamps are illuminated at night, the lamp beads inside the lamp housing are in the working state for a long time, and the heat generated is accumulated inside the lamp housing and cannot be dissipated, which causes the temperature in the lamp housing to rise gradually, shortening the use of the street lamp Life, not only that, in the existing solar street lamps, the structural power of the lamp tube is fixed and single, and it cannot be adjusted in time according to the external light and dark conditions. When the lighting brightness is too high, it is easy to increase the power consumption of the street lamp When it is too dark, the safety of road traffic cannot be guaranteed, thereby reducing the practicability of existing solar street lights
