<P>PROBLEM TO BE SOLVED: To obtain an organic EL lighting fixture equipped with a plurality of organic EL panels arrayed in plane and capable of aiming at elongation of life for each organic EL panel. <P>SOLUTION: The organic EL lighting fixture 101 is provided with a light-emitting part 10 on which a plurality of organic EL panels 1a, 1b, 1c are arrayed planarly or in a curved surface. A panel area of those organic EL panels 1c arranged on the center side in the light-emitting part 10 out of the plurality of organic EL panels is set different from that of organic EL panels 1a arranged at an outer periphery side in the light-emitting part 10 out of the plurality of EL panels so that thermal stress given the organic EL panels 1c arranged on the center side in the light-emitting part 10 is alleviated to be nearly equal to that given to the organic EL panels 1a arranged at the outer periphery side in the light-emitting part 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
