what is Solar street lamp and working principle

The principle of solar street lamp - basic introduction

Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery, gel battery) to store electrical energy, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. There is no need to lay cables, no communication power, no electricity bills; Dc power supply and control; It has the advantages of good stability, long life, high luminous efficiency, simple installation and maintenance, high safety performance, energy-saving and environmental protection, economical and practical. It can be widely used in urban main, secondary road, residential area, factory, tourist attraction, parking lot and other places. Product parts lighting rod structure: steel lamp pole and bracket, surface spray treatment, the panel connection adopts special anti-theft stainless steel screws.

The principle of solar street lamp - working principle

Solar street lamp principle of work: during the day under the control of the intelligent controller of solar energy street lamp, solar panels after the illuminate of sunshine, absorb the solar energy light into electrical energy, solar battery components to the battery charge during the day, night batteries to provide electricity to power a LED light source, lighting functions. The dc controller ensures that the battery pack is not damaged by over-charging or over-discharge, and also has the functions of light control, time control, temperature compensation and lightning protection and anti-polarity protection.

Solar street lamp principle - system composition

Solar street lamp system can guarantee the rain weather over 15 days of normal work! Its system composition consists of LED light sources (including the driver), solar panels, battery (including battery insulation box), solar street light controller, street lamp light pole (base) and wire of accessories and so on several parts.

Solar cell components are usually made of monocrystalline silicon or polysilicon solar cells. LED lamp head generally chooses high power LED light source; Controller is usually placed in a light pole, relating to, the control, overcharge, discharge protection and reverse connect protection, the more advanced controller have the four seasons adjust the lighting time, half power, intelligent charge and discharge functions, etc.; The battery is usually placed underground or there is a special battery incubator, which can be used as a valve control lead acid battery, colloid battery, iron aluminum battery, or lithium battery. The solar lamps are fully automatic and do not need to dig the ditch, but the lamppost needs to be installed on the embedded parts (concrete base).

These are some of the working principles and some basic components of the solar street lamp. I hope you can understand. The application range of solar street lamp is very wide, as long as there is sunshine, can ensure the normal use of street lamp, do not need to worry about the problem of electricity, is very good lighting equipment.
