| titleOfInvention | Metal halide lamp device |
| abstract | (57) [Abstract] [Purpose] In a metal halide lamp device including a reflector and a metal halide lamp that is turned on by alternating current without providing an outer tube, color misregistration and reduction in illuminance maintenance rate during screen irradiation are reduced. A reflecting mirror having electrodes 2 and 2'on both ends, a base 3 provided at one end of an arc tube 1 in which a metal halide is sealed, and a reflecting surface such as a parabolic surface surrounding the arc tube 1. 6 is arranged so that the axis connecting the two electrodes of the arc tube 1 substantially coincides with the central axis of the reflecting mirror 6, and the arc tube 1 is placed on the bottom side of the reflecting mirror 6 from the mounting position where the maximum average illuminance is exhibited. Positioned and fixed to form a metal halide lamp device. |
