The composition of solar street light system and its advantages

Solar energy is inexhaustible, inexhaustible, clean, pollution-free and renewable green energy. Photovoltaic energy is considered to be the most important new energy in the 21st century because of its incomparable cleanliness, high security, relative universality and sufficiency of energy, long life and free maintenance.

The solar street lamp does not need to lay cables, no AC power supply, no electricity; 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, economic and practical. It can be widely used in urban main and secondary roads, residential areas, factories, tourist attractions, parking lots and other places. Lamp pole structure: steel lamp pole and bracket, surface spray treatment, panel connection using special anti-theft stainless steel screw.

Solar street lamp system can guarantee the normal work in rainy weather for more than 15 days! Its system consists of LED light source (including drive), solar panel, battery (including battery insulation box), solar street lamp controller, street lamp pole (including foundation) and auxiliary wire and other parts.

Solar cell modules generally choose monocrystalline silicon or polysilicon solar cell modules; LED lamp holder generally selects high power LED light source; The controller is generally placed in the lamp pole, with light control, time control, over-charge over-release protection and reverse connection protection, more advanced controller has four seasons to adjust the light time function, half power function, intelligent charge and discharge function; Batteries are generally placed underground or there will be a special battery insulation box, which can use valve-controlled lead-acid battery, colloidal battery, iron aluminum battery or lithium battery. The solar lamp works fully automatically without ditching and wiring, but the lamp pole needs to be installed on the embedded part (concrete base).

The LED light source

1. High luminous efficiency, low power consumption, long service life, low working temperature.

2. Strong security and reliability.

3. Fast reaction speed, small unit size, green environmental protection.

4. Under the same brightness, the power consumption is one tenth of the incandescent lamp and one third of the fluorescent lamp, but the life is 50 times of the incandescent lamp and 20 times of the fluorescent lamp. It is the fourth generation of lighting products after the incandescent lamp, fluorescent lamp and gas discharge lamp.

5. The advent of a single high-power ultra-bright LED makes it possible for the application field of LED to expand to the market of high-efficiency lighting source, which will be one of the greatest inventions of human beings after the invention of incandescent lamp by Edison.

Solar street lamp working principle:

During the day, the solar street lamp is controlled by the intelligent controller. The solar panel absorbs the solar light and converts it into electricity through the sunlight. During the day, the solar battery module charges the battery pack, and at night, the battery pack provides power to the LED light source to realize the lighting function. The DC controller can ensure that the battery is not damaged due to overcharge or overdischarge, and has the functions of light control, time control, temperature compensation, lightning protection, polarity protection and so on.
