<P>PROBLEM TO BE SOLVED: To provide an LED drive circuit etc. which can approximate the lighting control/color matching characteristics to those of an existing illumination lamp (e.g. an incandescent lamp) when an existing phase control type dimmer is used, and allows for lighting control/color matching with less discomfort. <P>SOLUTION: The LED drive circuit, to which a lighting control signal phase-controlled by a phase control type dimmer is input, controls a light-emitting section having a plurality of LED loads of different hues. The LED drive circuit comprises a lighting control/color matching section which performs lighting control and color matching of the light-emitting section by adjusting each current being fed to the LED load based on the lighting control signal thus input. <P>COPYRIGHT: (C)2012,JPO&INPIT |
