The led solar street light

As photovoltaic devices, high power LED device matures, more and more widely used solar street lamps, and solar street lamps controller as the core of solar street light system is an important component, its work directly influences the performance of the whole solar street lamps system



with solar photovoltaic devices, high power LED device matures, more and more widely used solar street lamps, and solar street lamps controller, which is the core of the solar street light system is an important component, its work directly influences the performance of the whole solar street light system.

according to the design requirements, the led solar street lamps 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 complete ascension or straight after filling, the controller into floating state, and the led solar street light 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 enough charging 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.

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 solar street lamps, and can make the street lamps remain the same under the different brightness of color temperature.
