For the betterment of the city, the street lights in the city have generally been changed to solar street lights. The traditional street lights used to be complicated to install, and also need to lay the circuit, maintenance costs are high, and the power consumed is also high.
Solar street lights are relatively inexpensive, energy-saving, and environmentally friendly, simple to install, have low maintenance costs, and do not require the laying of complex electrical circuits. With all these advantages, the demand for solar street lights is getting hotter and hotter.

Next, this article will introduce you to solar street lights in detail.

Ⅰ. Working principle of solar street light

Solar street light working principle: During the daytime solar street light under the control of an intelligent controller, solar panel after sunlight irradiation, absorbs solar light and converted it into electricity, charging the lithium battery. At night, the lithium battery provides electricity to power the LED light source to achieve the lighting function. The DC controller of the solar street light ensures that the lithium battery is not damaged by over-charging or over-discharging, and also has the functions of PIR human induction, light control, time control, temperature compensation, and protection against lightning and reverse polarity.

Ⅱ. Advantages of solar street lights

1. Wide range of energy sources

Solar outdoor street lamps use solar photovoltaic cells to provide electrical energy. Solar energy is unlimited as a new green and environmentally friendly energy source. Full use of solar energy resources, to alleviate the tension of conventional energy has a positive significance.

2. Simple and easy to install

The solar street light is simple and easy to install, no need to do a lot of foundation work such as laying cables like ordinary street lights, only need to have a base fixed, and all the wiring and control parts are placed in the light frame, forming a whole.

3. Low maintenance costs

IP65 solar street lights use solar power, except for rainy days when the conversion to mains power will produce a small part of the electricity cost, and the running cost is almost zero. The whole system is automatically controlled and requires no human intervention, resulting in virtually no maintenance costs.

Ⅲ. Applications of solar street lights

  1. Road street lighting in villages, towns and other marginal areas, etc.
  2. City squares, car parks, school playgrounds, greens, parks lighting, etc.
  3. Golf courses, seaside baths, high-grade villa areas, and other lighting, etc.
  4. Highway warning signs, bridge street light power replacement, etc.
