The solar street light system refers to a set of independent distributed power supply system that constitutes the solar street light. It is not subject to geographical restrictions, is not affected by the location of power installation, and does not need to excavate the road surface for wiring buried pipe construction. On-site construction and installation are very convenient. , the comprehensive economic benefit is good, especially it is very convenient to add solar street lights to the roads that have been built.
Especially in road lights, outdoor billboards, and bus stops far away from the power grid, its economic benefits are more obvious.
1. Overview of solar street lights:
Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-regulated sealed batteries (colloidal batteries) store electric energy, super bright LED lamps are used as light sources, and are controlled by intelligent charge and discharge controllers, which are used to replace traditional public electric lighting. Street lights do not need to lay cables, do not need AC power supply, and do not generate electricity bills; adopt DC power supply and control; have 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, etc. Widely used in urban main and secondary arterial roads, residential areas, factories, tourist attractions, parking lots and other places.
Introduce the general cost, working principle, components, advantages, parameters, installation steps and selection methods of solar street lights.
The solar street light system is composed of eight elements. That is, solar panels, solar batteries, solar controllers, main light sources, battery boxes, main lamp holders, lamp poles and cables.
2 How solar street lights work
Description of the working principle of solar street lights: during the day, the solar street lights are under the control of the intelligent controller, the solar panels are irradiated by sunlight, absorb solar light and convert it into electrical energy, the solar battery components charge the battery pack during the day, and the battery pack provides power to the LED at night The light source is powered to realize the lighting function. The DC controller can ensure that the battery pack will not be damaged due to overcharge or overdischarge. It also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.
