Patent ID: 8154683

Claim:
A method for manufacturing an illumination device in which a chip-type LED is mounted on a flexible strip-like wiring board having a partial ring shape or a linear shape, and the wiring board is rounded into a truncated conical shape or a cylindrical shape with end edges of the wiring board being brought into abutting contact with each other, the method having: a through-hole forming step of, in the wiring board, providing a through-hole for filling solder paste at a wiring end portion to be connected with a terminal of the LED; a mounting step of temporarily fixing the LED with bond onto the wiring board in a plate-like state, and filling the through-hole with the solder paste from a back surface of the wiring board; a rounding step of rounding the wiring board into the truncated conical shape or the cylindrical shape, the wiring board being mounted with the LED in the mounting step and having the through hole filled with the solder paste; and a soldering step of reflowing the wiring board in a rounded state.
