LIGHTING CONTROL DEVICE FOR ORGANIC ELECTROLUMINESCENT PANEL

摘要

PROBLEM TO BE SOLVED: To provide a lighting control device for an organic electroluminescent panel with enhanced safety by detecting abnormal operation of the organic electroluminescent panel in an accurate manner.

SOLUTION: The lighting control device includes: a power supply unit for providing power to an organic electroluminescent panel for operation thereof; a current detector for detecting a current value flowing in the organic electroluminescent panel; a voltage detector for detecting a voltage value applied to the organic electroluminescent panel; and a controller that determines if the current value detected by the current detector and the voltage value detected by the voltage detector are within a safety domain on a voltage-current plane predetermined based on a voltage-current characteristic curve of the organic electroluminescent panel, and stops supplying power from the power supply unit to the organic electroluminescent panel when the detected current value and voltage value are determined to be outside the safety domain.
