<P>PROBLEM TO BE SOLVED: To provide an array of LED lamps which can be made compact. <P>SOLUTION: A substrate 21 on which an LED element 22 is mounted is composed of a single-layer substrate or multilayer substrate, a pair of electrode terminals 23 and 24 for making the LED element 22 emit light and a pair of bypass terminals 27 and 28 for providing a bypass circuit are provided on a reverse surface 21b of the substrate 21, and a bypass pattern 29 connecting the pair of bypass terminals 27 and 28 is provided on the reverse surface 21b of the substrate 21. The pair of electrode terminals 23 and 24 are provided on one diagonal of the substrate 21 at or near corners, and at least the pair of bypass terminals 27 and 28 are provided on the other diagonal where the electrode terminals are not provided at or near corners. <P>COPYRIGHT: (C)2009,JPO&INPIT |
