Under the background of energy shortage, with solar photovoltaic devices, high power LED device of mature, solar street lamp
is more and more widely used.
Solar street lamps controller as LED solar street light system, an important component of the work performance directly affects the whole function of solar street light system.
System by the solar panels , the LED street lamp controller, lead-acid battery and LED street lamp module.
Throughout the system, solar street lamp controller in the core position, the work is good or bad directly determine the performance of the whole system.
This controller has the battery overcharge, discharge protection, solar battery over-voltage protection, load short circuit protection and other protection function.
According to the design requirements, controller in startup time determined according to the state of battery charging mode, charging if the battery is in a state have put into ascension charging mode;
If the battery is under-voltage state into direct charge mode;
If the battery in a floating state into floating mode, if the battery itself overpressure continued to stay in the overpressure alarm state.
When the complete ascension or straight after filling, controller into floating state, when the battery voltage due to the electricity load and fell to below fill continuously return point, the controller back into direct charge state.
At this point, if the load continues to electricity and solar panels can't provide enough charge energy storage battery voltage continues to fall to under-voltage and even put some of the following, controller into the discharge protection, close the load and to improve charging status.
In practice, people often hope street lamp in the middle of the night when can reduce brightness, solar street light controller is very well done just that.
This one is for the purpose of energy saving, 2 it is to the service life of the , and can make the street lamps remain the same under the different brightness of color temperature.
Before the street lamp is does not have power control or dimming function.
Therefore, this approach can achieve this purpose.
