<P>PROBLEM TO BE SOLVED: To alleviate luminance unevenness when lighting, with a single lighting device, a plurality of light-emitting modules connected in parallel in column between a pair of power-feeding rails. <P>SOLUTION: Between a power-feeding rail 2a equipped with a power-feeding terminal 3a at one end and a power-feeding rail 2b equipped with a power-feeding terminal 3b at the other end, light-emitting modules A1 to An are arrayed in column and electrically connected in parallel, and driving voltage is fed from the lighting device 5 through power-feeding lines 4a, 4b. With this, electric passage lengths of the light-emitting modules A1 to An become all equal, thereby making impressed voltages all equal to have light emitted at the same luminance. <P>COPYRIGHT: (C)2009,JPO&INPIT |
