Abstract
Disclosed is an organic EL illuminating apparatus which can detect a short-circuit when the short-circuit is generated in one area between the anode and the cathode. The organic EL illuminating apparatus is provided with: an organic EL illuminating device (1); a drive circuit (2) which turns on the organic EL illuminating device (1); an illuminance detection monitor (3) which monitors the lighting state of the organic EL illuminating device (1); and a monitor detection signal feedback circuit (4) which makes the drive circuit (2) turn off the organic EL illuminating device (1), on the basis of monitor information obtained from the illuminance detection monitor (3).
