ORGANIC EL ELEMENT LIGHTING DEVICE AND LIGHTING FIXTURE USING THE SAME

An object of the present invention is to provide an organic EL element lighting device whereby surge current can be reduced at start-up while controlling start-up variation, along with a lighting fixture using the same. Provided are a current supply part for supplying lighting current to a light source formed of one or more organic EL elements and connected between output terminals of the current supply part, a current detection part for detecting the lighting current, a target setting part for setting a target value of the lighting current, and a control part for performing feedback control of the lighting current by controlling the current supply part so that the detected value of the current detection part matches the target value of the lighting current. The target setting part has a sweep period during which the target value is gradually increased at start-up of the light source.
