<P>PROBLEM TO BE SOLVED: To provide a lighting unit with assembly and maintenance facilitated, and yet, having a connection structure excellent in reliability. <P>SOLUTION: The lighting unit, provided with a light-emitting source mounted on a circuit board, and a base fitted to a side contrary to a light-irradiating side from the light-emitting source, is so structured that electrode pins of the base penetrate the circuit board and are directly fixed to the circuit board while being electrically connected to a wiring pattern conducted to the light-emitting source on the surface of the circuit board mounting the light-emitting source. Thus, without using lead wires as are used in a prior art, a connection structure with assembly and maintenance of the lighting unit facilitated and excellent in reliability is realized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
