摘要： The present invention concerns an LED drive device which is arranged in such a way as to be able to block leakage current and which is also arranged in such a way as to be able to smoothly drive the LED. The LED drive device of the present invention is one in which LED modules arrayed on a metal PCB are connected to a plurality of regular-power-source input lines, and it comprises cut-off elements which are respectively provided on all of the input lines of the LED modules connected to the plurality of regular-power-source input lines and which are for cutting off the regular-power-source input to all of the input lines of the LED modules. When switched off, both sides of the regular-power-source input line are turned off. Consequently, in principle, there is no scope to produce any leakage current since there is no way that an electrical potential could be generated in the circuit layer (copper foil) of the metal PCB. More specifically, when it is switched off, the LED module (alternating-current LED module) is immediately turned off and thus not only can operational reliability be ensured but also unnecessary power loss is prevented.
