<P>PROBLEM TO BE SOLVED: To provide a mounting member excellent in heat dissipation and easy to make electrical connection in manufacturing, and a light source device including the member. <P>SOLUTION: A heat sink 2 having a threaded hole 21 having an internal thread formed on its inner periphery, the mounting member 3 including a thread 31 having an external thread screwed with the internal thread formed on its outer periphery, a mounting part 33 protruding from the thread 31 in the axial direction of the external thread and formed to be radially smaller than the thread 31 and a wiring hole 35 passing axially through the thread 31, and a light source part 4 mounted on the mounting part 33 of the mounting member 3 and having a LED element are provided. Heat transfer to the heat sink 2 is excellent since a contact area between the mounting member 3 and the heat sink 2 is large. In addition, the mounting member 3 can screw with the heat sink 2 while a wire 7 is connected with the light source part 4. <P>COPYRIGHT: (C)2009,JPO&INPIT |
