<P>PROBLEM TO BE SOLVED: To physically couple a plurality of printed boards while electrically connecting them simply and easily in a very simple structure and yet in a state of minimized contact failure. <P>SOLUTION: The lighting device physically couples a plurality of printed boards 2 and at the same time, electrically connects them so as to make fixed light-emitting diodes 1 emit light. Each printed board 2 has a through-hole 4 opened for inserting a lock tool 3, around which 4, a conductive part for connection 5 is fitted at both faces while insulating them from an inner face of the through-hole 4. The printed board 2 fixing the light-emitting diodes 1 supplies power from a pair of conducive parts 5 for connection to the light-emitting diode 1 through a lead conductive part 6 on the surface. The plurality of printed boards 2 are electrically connected by electrically connecting the conductive parts 5 in contact in opposition by laminating the through-holes 4 so as to coincide with each other, coupling the printed boards 2 in a laminated state with the conductive lock tools 3 inserted into the through-holes 4, and by making both ends of the lock tools 3 contact with the conductive parts 5 for connection of front surface side. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
