Light control apparatus and lighting appliance using the same

Abstract

It is objected to provide a light control apparatus and a lighting appliance using the same which enable to increase luminous efficiency in the light control and to elongate operative life of a light source. The lighting appliance comprises a light source 1 and a light control apparatus 2. The light control apparatus 2 comprises an electric current output circuit 5 which outputs a constant electric current for lighting to a light source configured of an organic electroluminescence device, a light control circuit 6 which performs light control of the light source 1 by intermittently supplying the constant electric current outputted from the electric current output circuit, and an electric discharge prevention circuit (diode) 70 which prevents electric discharge of an electric charge charged in capacitive component of the organic electroluminescence device.
