<P>PROBLEM TO BE SOLVED: To provide a lamp which suppresses heat load on a circuit unit when the lamp lights. <P>SOLUTION: A lamp comprises: a reflecting mirror 7 having a concave reflection surface 75; an LED module 3 provided in the reflecting mirror 7; a mouth piece 13 attached to a base part 71b of the reflecting mirror 7; a circuit unit 11 for receiving electric power through the mouth piece 13 and making the LED module 3 emit light; and a columnar light guide member 20 which has one end surface 21b arranged so as to face the LED module 3, allows the light emitted from the LED module 3 to enter, and guides the light to an emission part 21a on the other end to emit the light. The light guide member 20 is provided in the reflecting mirror 7 so that the emission part 21a is positioned at a focal point 1 of the reflecting mirror 7, and at least part of the circuit unit 11 is attached to a region of an outer periphery of the light guide member 20 excluding the emission part 21a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
