<p><P>PROBLEM TO BE SOLVED: To provide a two-wire system load control device, of which the illumination load eliminates false lighting or flickers at light-off times, and which is capable of controlling the turn on/off of the illumination load, and lowering power consumption at standby. <P>SOLUTION: In the two-wire system load control device provided with an illumination load 12, and a microcomputer 15 controlling an operation of an on-peaker 17 operating in interlocking with an operation of the illumination load, the microcomputer as a control unit operates the control device alone at a low consumption power by a low current that is not sufficient to turn it on with a main control load and a sub control load at standby at the stoppage of operation of the both loads, so that, when an input enough to turn on the main control load is detected, the main control load, as well as the sub control load, is made to operate; and when an input for turning off of the illumination load is detected, the main control load is turned off, after the sub control load has been turned off, to carry out a control of the standby state at low consumption power. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
