<P>PROBLEM TO BE SOLVED: To provide a device having more uniform lighting with low resistance and a device which can be utilized in other uses in a lighting device capable of simply, easily and freely changing coupling positions of light-emitting diodes. <P>SOLUTION: The lighting device is equipped with a plurality of light-emitting diodes 1 having projected leads 2, and a power supply sheet for coupling the leads 2 of the plurality of the light-emitting diodes 1 therewith in a state that they are electrically connected. In the power supply sheet, first and second sheet-like conductive layers containing carbon fibers and having flexibility are tightly adhered to each other while pinching an insulating layer having the flexibility. In the lighting device, short leads of the light-emitting diodes are inserted into the first sheet-like conductive layer to be electrically connected to the first sheet-like conductive layer, long leads are passed through and inserted into the first sheet-like conductive layer and the insulating layer to be connected to the second sheet-like conductive layer, and by insulating at least parts of the long leads connected to the first sheet-like conductive layer and by making electrical connection to the long leads from the second sheet-like conductive layer, the light-emitting diodes are energized to make them emit light. <P>COPYRIGHT: (C)2008,JPO&INPIT |
