<P>PROBLEM TO BE SOLVED: To reduce the waste of resources associated with replacement of a broken LED. <P>SOLUTION: A substrate 110 (a printed wiring board) has substantially rectangular shape. Engagement convex portions 111 are located on any long side of the substrate 110. Engagement recess portions 112 are located on the opposite side to the long side of the substrate 110, on which the engagement convex portions 111 are located. LEDs 120 (light-emitting diodes) are mounted on the substrate 110. A female contact 133 (a positive-electrode connection terminal) is electrically connected to anodes electrodes 121 (positive electrodes) of the LEDs 120 and is located on any short side of the substrate 110. A male contact 143 (a negative-electrode connection terminal) is electrically connected to cathode electrodes 122 (negative electrodes) of the LEDs and is located on the opposite side to the short side of the substrate 110, on which the female contact 133 is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
