solar street lamps controller switch mode

1, the optical - optical close principle: during the day, LED street light, the sun to the surface of a solar cell components, photovoltaic effect produce power, and through the controller for battery charging; As the waning light, solar battery components produce voltage falling, when the voltage value is lower than the voltage value, the controller is set to start the controller to start the work load. Light gradually strengthen, battery components produce voltage increase and achieve controller set off voltage value, the controller to cut off the load. 2, electric off - time control on principle: during the day, the sun to the surface of a solar cell components, photovoltaic effect produce power, and through the controller for battery charging; As the waning light, solar battery components produce voltage falling, when the voltage value is lower than the voltage value, the controller is set to start the controller to start the work load. When work load reaches preset time controller, time controller to cut off the load, load stop working. 3, the control principle of on - time control off: when the sun to the surface of a solar cell components, photovoltaic effect produce power, and through the controller for rechargeable battery. Time to controller set a time when controller to start the work load. When work load reaches preset time controller, time controller to cut off the load, load stop working.
