LED BEACON LIGHT LIGHTING DEVICE AND LED BEACON LIGHT

摘要

PROBLEM TO BE SOLVED: To provide an LED beacon light lighting device used at low light intensity capable of automatically switching connection in a current transformer at the time of actual usage and scheduled inspection, and an LED beacon light equipped with the above LED beacon light lighting device.;SOLUTION: The LED beacon light lighting device 1 is provided with a current transformer 2, a light-emitting diode 4 lighting by selectively supplying electric current through an output winding 2b of the current transformer 2 or a middle tap 8c, electric current detection means R1, R2, 5 for detecting electric current flowing in the light-emitting diode 4 and outputting control signals corresponding to the detected current value, and a connection switching means 6 for making the output winding 2b of the current transformer 2 or the middle tap 8c supply current to the light-emitting diode 4 in response to the control signal.;COPYRIGHT: (C)2008,JPO&INPIT
