摘要: PROBLEM TO BE SOLVED: To provide a light-emitting device capable of fixing luminance even if color an organic EL element is changed. SOLUTION: An illuminator 11 comprises panel 12 with as light-emitter and driving circuit 13 for applying DC voltage to the 12. The conversion 14 connected power source Vcc, its output terminals 14a, 14b are One terminal via switching 15. A control 25 outputs chrominance signal Sc Sb so set by input device. converts Vcc into predetermined voltage, it based on outputted from 25. drive 26 performing PWM ON/OFF operation 15 COPYRIGHT: (C)2006,JPO&NCIPI
