The present invention provides an energy-saving LED street lamp and a method of saving energy with said LED street lamp. A energy-saving LED street lamp comprises lamp body, power supply adapters, constant current actuating device, and LED lamps. said constant current actuating device is connected in series with the outpu t end of the Power supply adapter, supplying power to said LED lamps. Said energy-saving lamp also comprises auto light-dimmer energy-saving controller; the signal output end of said auto light-dimmer energy-saving controller being connected with constant current actuating device. Said LED lamps compose a plurality of working module; each of the said working module is connected with an independent Power supply adapter. Said auto light-dimmer energy-saving controller has a plurality of routes of output signal, and each of the route of signal output end is connected with a constant current actuating device, and sequentially control the lighten and extinguish time of a working module . A method of saving energy with said LED street lamp is published, too. The working ti me each day of LED street lamp is divided into a plurality of working time period on the basis of the measure of light used, and then different quantities of working modules are turned on in different time period controlled by the auto light-dimmer energy-savin g controller on the basis of the measure of light used. |
