<P>PROBLEM TO BE SOLVED: To provide a large area organic EL lighting apparatus which uses an organic EL lighting panel to emit light evenly, with a reduced dark section and with less unevenness in brightness than ever, with a simple configuration and at low cost. <P>SOLUTION: The organic EL lighting apparatus is composed of organic EL lighting units which are juxtaposed with one another, the directions of their light-transmitting bottom faces being aligned with each other. The organic EL lighting units each consist of a hollow polygonal column and organic EL lighting panels 4, disposed on at least one face on the sides of the polygonal column, which emit light to the inside of the polygonal column. A bottom face on one side of the polygonal column transmits light, and a bottom face on the other side transmits light or comes with a reflection plate 5 which reflects the light of the organic EL lighting panels 4 toward the inside of the polygonal column. <P>COPYRIGHT: (C)2013,JPO&INPIT |
