Abstract
A method of controlling an illumination apparatus includes a malfunction detecting step for detecting a malfunction of an organic electroluminescence element based on its electrical characteristic, a short-circuit malfunction restoration step for applying a short-circuit malfunction restoration pulse to an element that is determined to be a short-circuit malfunction, a short-circuit malfunction restoration determination step for determining whether the element that is determined to be the short-circuit malfunction is restored, a malfunctioning element determination step for storing into a storage, when an element that is determined to be the short-circuit malfunction is not restored, individual information including identification information on the element as a malfunctioning element, and a turn-on control step for controlling the turn-on state of a light-emitting surface based on a state of distribution of the malfunctioning organic electroluminescence elements.
