PURPOSE:To miniaturize a lamp and realize a highly efficient condensing characteristic over a wide range. CONSTITUTION:A reflector main body 10 is such constituted that a band-like third reflecting curved surface 10c is disposed continuously to the intermediate portion between a first and a second reflecting surface 10a, 10b which cut a parabolic curve in the direction of the optical axes so as to provide two optical axes parallel to each other. A lamp main body 11 is positioned on a focal point of the reflector main body 10 in such a manner that both ends of an arc 11a correspond to both sides of the third reflecting surface 10c with the optical axis of the reflector main body 10 being approximately perpendicular to the optical axes of the lamp. |
