Abstract

The invention provides a dimming device to adjust lighting load of light output with high capacity while preventing occurrence of high frequency noise and also achieve high heat dissipation characteristic and miniaturization. The dimming device includes a triac and a serial circuit having a pair of IGBTs connected among main terminals of the triac and also includes a power module 5 and a control circuit. The triac and the pair of IGBTs are provided on the aluminum substrate of the power module 5 by bare chip packaging, respectively. The control circuit turns on the triac with a phase angle corresponding to dimming level set by variable resistance VR at first and controls the impedance of one of the pair of IGBTs to smoothly increase loading voltage for applying on the lighting load. The power module 5 is thermally combined with a fitting plate 4 as fitting member material provided on the application surface of the power module 5 while a heat dissipating plate 6 is provided in between.
