<P>PROBLEM TO BE SOLVED: To provide a planar lighting source composed of a belt-shaped LED unit formed by mounting a plurality of LEDs connected to each other on a belt-shaped base plate with an appropriate distance, having switching circuits interposed between the LEDs at appropriate positions. <P>SOLUTION: The planar lighting source made to constitute an illumination body having a prescribed area is formed by preparing the belt-shaped LED unit formed by mounting a plurality of LEDs connected to each other on a belt-shaped base plate with an appropriate distance, having switching circuits interposed between the LEDs at appropriate positions, intercalating a switching circuit at an appropriate position between the LEDs, and arranging the plural number of the LED units at a given interval and connecting them sequentially. <P>COPYRIGHT: (C)2007,JPO&INPIT |
