Introduces a solar street lamps controller applied dynamic | | industry lighting: solar led street lamp manufacturers in the countryside
Solar street lamps controller not only is a simple work open during the day close control street lamp at night, it also has the battery overcharge, discharge protection, solar cells, over-voltage protection, load short circuit protection and other protection function.
In recent years, we can find that high power LED and solar photovoltaic components of cost reduction, coupled with the shortage of energy is getting big background, the scope of the popularity of solar street light.
The solar street light system is one of the core components of solar street light controller is good or bad directly affect the work of the whole of the street lamp system stability.
Controller in the 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 complete ascension or straight after filling, solar street lamps 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, solar street lamps controller into the discharge protection, close the load and to improve charging status.
Solar controller can also according to the demand of people, can lower the brightness in the middle of the night.
In this way, can achieve the effect of energy saving, and can guarantee the service life of the solar street lamps, and can make the solar street light under the different brightness still keep the same color temperature.
Before the street lamp is does not have power control or dimming function.
