Intelligent solar street lamp illumination system

Abstract

The invention discloses an intelligent solar street lamp illumination system which comprises an MPPT solar charging and discharging controller, a photovoltaic battery, a storage battery, an induction module, a control module and an illumination lamp. The MPPT solar charging and discharging controller detects power generation voltage of the photovoltaic battery in real time, and tracks the highest voltage and current value, the system outputs the maximum power to charge the storage battery, working of the photovoltaic battery and working of the storage battery are coordinated, and the working life is prolonged; a light sensor in the induction module detects the environment light intensity, a photoelectric sensor detects the visibility changes in air, converts the visibility changes into electric signals and transmits the signals to the control module, a power control unit or a voltage stabilizing control unit in the control module controls an illumination lamp to automatically adjust the light brightness, the working power of a solar street lamp is reasonably distributed, and the system saves energy and is environmentally friendly.

Description

technical field [0001] The invention relates to the field of solar lighting systems, in particular to an intelligent solar street lamp lighting system. Background technique [0002] Solar energy is an inexhaustible, clean, pollution-free and renewable green energy source. The use of solar power, unparalleled cleanliness, high security, relative breadth and sufficiency of energy, long life, and maintenance-free and other advantages that other conventional energy sources do not have, photovoltaic energy is considered to be the 21st century The most important new energy. The solar street lamp does not need to lay cables, does not need AC power supply, and does not generate electricity bills; it adopts DC power supply and control; it has the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical. It can be widely used in urban main and ...

AI Technical Summary

Problems solved by technology

[0003] At present, the power of solar street lamps is basically unchanged when they are working. When lighting, in dark places or bright places, the brightness of the lights provided is the same, and the lighting power cannot be allocated reasonably, resulting in certain energy losses.
