For achieving the above object, intelligent street lamp control device of the present invention comprises that the protective tube, of an assurance circuit safety operation carries out the Inductive ballast of the capacitor of power factor correction, a stabling current and a triggering and light the trigger of street lamp, this intelligent street lamp control device separately comprises an electricity-saving appliance, the input of this electricity-saving appliance and this Parallel-connected Capacitor, one end of output is connected with this Inductive ballast, and the other end is connected with this trigger.

Further, this electricity-saving appliance comprises an electric capacity, a transformer, a MCU microcomputer, a sample circuit and a power drive output circuit.

Further, the input phase of this electric capacity and this transformer also connects, two output windings of this transformer are connected with this sample circuit with 5V pressurizer respectively, 220V power supply is connected with this sample circuit, this MCU microcomputer input is connected with this sample circuit, this MCU microcomputer is separately connected with this power drive output circuit, and the input of this power drive output circuit is with this electric capacity and connect, output is connected with this Inductive ballast, this trigger respectively.

The present invention fully takes into account the deficiencies in the prior art, by microcomputer and the effective combination of electronic power saver for street lamp, make the present invention go for any Europe superscript Inductive ballast, street lamp is effectively regulated, reach the effect of firm power, and can carry out timing dimming by the control of microcomputer to street lamp as required, thereby for country has saved electric power resource, and can greatly extend useful life of Inductive ballast and street lamp.
