<p><P>PROBLEM TO BE SOLVED: To reduce the risk of peeling from a metal plate 4 of a flexible board 2 while supprissing an assembling cost, and to reduce stress applied to solder sections of LEDs 1a, 1b and 1c. <P>SOLUTION: A stepped base member 5 and the approximately-complementary shaped metal plate 4 are supplied. The rear of the flexible board 2 at places (2a, 2b and 2c) mounting the LEDs 1a, 1b and 1c on its surface in the rear of the flexible board 2 mounting the LEDs 1a, 1b and 1c is joined with the surface of the metal plate 4. The rear of the flexible board 2 at the places (2a' and 2b') mounting no LED 1a, 1b and 1c on its surface is not joined with the surface of the metal plate 4 in this case. The metal plate 4 joining the flexible board 2 is fixed to the base member 5. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
