With the exit of many old-fashioned street lamps from the market, solar smart street lamps have become the mainstream choice for street lamps. Solar street lamp manufacturers point out that solar smart street lamps are mainly composed of solar cell modules, high-performance maintenance-free batteries, controllers, LED light sources and lamp bodies. On the equipment, a vertical power supply system is adopted, eliminating the need for cable burial. It features automatic charging, automatic light source switching, simple construction, no manual operation required, stable and reliable operation, and a long service life. It features safety, energy conservation, environmental protection, usefulness, high efficiency and simple equipment. It is suitable for places such as municipal construction, parks, scenic spots, courtyards, villas, residential areas, and enterprise decoration that require lighting and visual effects.
During the day, sunlight shines on the solar modules, generating a certain level of DC voltage in the solar cell modules, converting light energy into electrical energy, which is then transmitted to the controller. Through the overcharge protection of the intelligent controller, the electrical energy transmitted by the solar modules is sent to the battery for storage. At night, as the solar modules cannot receive light energy, the intelligent controller automatically opens the control equipment, and the battery passes through The over-discharge protection device of the intelligent controller supplies power to the LED light source, promoting the LED light source to declare satisfactory brightness for lighting. At dawn, the solar modules receive light energy again, and the intelligent controller automatically switches to the charging method for operation.
The solar controller is the core component of the solar smart street lamp, featuring many functions such as light control, time control, charging and discharging. During operation, it is necessary to maintain dryness. The internal design is programmed and input. Do not touch the buttons at will. If there are any defects, they must be operated by professionals. The solar controller adopts a low-frequency PWM half-bridge extension supplementary power main circuit, which reduces the voltage loss in the charging circuit by nearly half compared to the charging circuit using diode anti-reverse charging. The charging power is 3% to 6% higher than that of non-PWM, increasing the power consumption time. Advanced charging for over-discharge recovery and normal equalization charging.
The circuit board of a solar street lamp is a component with a relatively long service life in a solar smart street lamp, which can last up to 35 years. During use, if it doesn't rain for several consecutive days, a lot of soil and dust will fall on the surface of the solar panel, affecting the power generation capacity. Manual cleaning is necessary when needed. Keep the solar panel facing south. If it shakes, replace it in time.
