Generally, street lights are powered by communication power. Even LED street lights are rectified into DC power after communication. Power resources are becoming more and more serious. Nowadays, energy conservation and environmental protection are considered, and solar energy can be recycled without pollution. Therefore, more and more cities are replacing street lights with solar street lights, which is environmentally friendly and reduces financial expenses.
The composition of solar street lights.Solar street lights are composed of solar panels, solar manipulators, batteries, LED drive modules, LED street lights, and street light poles. The system composition block diagram is shown below. The effect of solar panels The effect of solar panels is to collect light and convert light energy into electrical energy. It is the core component of solar street lights. The output voltage, output current, peak power and conversion power should be considered in the selection of solar panels. The output of solar panels is direct current. The efect of the manipulator The manipulator is the brain of the entire system, primarily playing the role of charge and discharge management. Whenthe daylight is relatively strong, the controller closes the street lights, and controls the solar panels to charge the battery and stores the battery;atnight, the controller lights up the LEDs, and controls the battery discharge together to convert the voltage into a suitable LED There is a light control module in the manipulator, which is generally a photosensitive circuit composed of a photosensitive resistor.
The effect of the battery The battery plays the effect of storing electric energy, storing the electric energy converted from daylight, and powerig the LED lights at night under the effect of the controller, so that the LEDs are lit to have a lighting effect. In short, the general street lights arechanged. In order to become solar street lights, solar panels, solar manipulators, battery lights, and perhaps LED drivers will be added.
