Solar street lamp

Abstract

A solar street lamp comprises a lamp post, an illuminating lamp, a solar cell panel, a mainframe box, a photosensitive sensor and an infrared detector. An inverter, a power supply module and a single-chip microcomputer are arranged in the mainframe box; the illuminating lamp comprises a first shell, a heat dissipation plate, a second annular plate, a mounting plate, a driving power supply, a baseplate and a second shell; the mounting plate is connected with the first shell; a first annular plate is arranged on the first shell; the second annular plate is arranged on the second shell; the second annular plate, the first annular plate and the heat dissipation plate are detachably connected; the driving power supply and the base plate are respectively arranged on the heat dissipation plate;lamp beads are arranged on the base plate. The infrared detector and the photosensitive sensor are connected with the single-chip microcomputer. The signal output end of the single-chip microcomputeris connected with the signal input ends of the illuminating lamps. The solar cell panel is connected with the lamp post through a mounting frame and connected with the inverter. The inverter is connected with a power supply module for supplying power to the electric appliance elements. The illuminating lamp is convenient to use, can be intelligently controlled to be turned on, and is good in heatdissipation performance.

Description

technical field [0001] The invention relates to the technical field of solar street lamps, in particular to a solar street lamp. Background technique [0002] Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. Street lights are widely used in various places that need lighting; with the development of science and technology, solar street lights are widely popularized; solar street lights are road lighting devices that use photovoltaic cells to directly convert solar energy into electrical energy for utilization. Solar street lights can be charged independently during the day and used at night without laying any complicated and expensive circuit pipelines. Turn on and off; turn on the street lights in the evening, turn off the street lights in the early morning, and continue to run at night; when there are no pedestrians on the road, or when the sky is not dark, the street ...

AI Technical Summary

Problems solved by technology

Solar street lights can be charged independently during the day and used at night without laying any complicated and expensive circuit pipelines. Turn on and off; turn on the street lights in the evening, turn off the street lights in the early morning, and continue to run at night; when there are no pedestrians on the road, or when the sky is not dark, the street lights continue to run at full capacity, which greatly increases the waste of electric energy and greatly increases the loss of street lights. Reduce its service life; if the street lamp continues to run at full load, if the heat energy generated inside it cannot be effectively discharged, the service life of the street lamp will be greatly reduced; for this reason, a solar street lamp is proposed in this application
