Solar street lights differ from regular street lights in that they utilize solar panels as the power supply. Due to the high cost of solar panel components at that time, it was necessary to use good light sources to reduce system costs.
The selection of light sources, control circuits, the determination of the tilt angle of solar panels, the capacity of solar components, and battery capacity are key aspects of solar street lighting systems, which can further enhance energy-saving development.
LED light sources are semiconductor light-emitting devices that convert electrical energy into visible light. In recent years, LED technology has made significant breakthroughs, improving performance-to-price ratios and exhibiting high luminous efficiency compared to traditional street light sources.
Solar street light systems are generally small photovoltaic power generation systems. The self-consumption current of the controller in small photovoltaic power generation systems is less than 1% of the rated working current, making the selection of controllers and low-power devices very important.
The control circuit in solar street lights typically uses an integrated voltage comparator. This circuit is a control system composed entirely of hardware, which is simple, reliable, easy to maintain, low-cost, and has low power consumption, making it a compatible circuit.
Solar street light manufacturers use monocrystalline silicon solar panels for power supply, and lithium batteries for energy storage, employing energy-saving lighting devices and advanced charge-discharge and lighting control circuits. This enhances functionality and further improves economic benefits, representing the future direction of outdoor lighting development.
