Description

 Solar lights are the work of automatic control system, simply set the operating mode of the system will automatically control.Control mode is generally divided into three types: light starts control;light control off; timing start control and timing off control;

the low light in the sun to set value light sensor control start working, start timing the same time. When the time to set the time to stop working. The solar system has two functions: First, battery charging during the day; Second, do light-control sensors, components of the charge and discharge with the RC. We generally use *8 watt or *6 watt low pressure sodium lamp as light source, because its the highest optical efficiency in the light. Solar street lights with high efficiency single crystal (multi crystal) silicon solar battery, sealed maintenance-free battery storage with power, using energy efficient lighting and advanced lighting control circuit charge and discharge and with the nature of reliable, high luminous efficiency, Brightness, easy installation, no need to lay cables and wires, no exchange of energy and electricity, the use of DC power supply, sensitive control, safe, reliable, energy saving, economic, environmental and practical (depending on configuration and the model, one can charge 3 to 7 days )long life (solar cell can be *5 to *0 years, the battery can be 5 to 7 years)
