The structure of
solar cat eye road stud system is shown in following Figure. It is mainly composed of solar panel, solar controller, battery, LED light source and shell.
Solar panel is the core part of solar street lamp and the most valuable part of solar cat eye road stud. Solar panel is a semiconductor device with PN junction. According to the photovoltaic principle, solar energy can be directly converted into electric energy. Battery is a kind of energy storage element, which stores the electric energy converted from solar cells in the daytime, and provides electric energy to street lamps at night.
The function of the controller is to prevent the battery from overcharge and deep discharge. At the same time, it has the function of temperature compensation and road light control. The controller has the function of automatic load switching at night, so as to extend the working time of road light in rainy days. As an environmental protection and energy-saving semiconductor light source, LED has a strong development momentum and is the most ideal light source for solar cat eye road stud.
Advanced power electronic technology is used in the
solar cat eye road stud, and the driver is designed to provide stable power supply. At the same time, two output modes of high efficiency enhanced and ultra energy saving pulse width modulation (PWM) are designed.
With time control, solar cat eye road studs can be turned on in high efficiency enhanced mode when necessary (many pedestrian and vehicles or under extreme low light condition in the first half of the light) to provide good lighting, while other time periods (few pedestrian and vehicles in the second half of the night) can be output in super energy-saving mode, which can save the power consumption of battery and prolong the working time of street lamps.
