| titleOfInvention | Metal halide lamp device |
| abstract | (57) [Summary] [PROBLEMS] To provide a metal halide lamp device capable of shortening the arc length to increase the screen illuminance and reducing the devitrification rate to improve the screen illuminance maintenance rate. A metal halide lamp device comprising a reflecting mirror 8 and a metal halide lamp which is lit only by an arc tube 1 arranged such that an axis connecting the electrodes 2 and 2'is aligned with a central axis of the reflecting mirror 8, The projection length of the electrode 2'on the side of the reflecting mirror opening of the arc tube 1 is made longer than the projection length of the other electrode 2 and a reflection and heat insulating film 5 is provided on the outer surface of the arc tube around the electrode 2'having a long projection length. , The distance between the buried positions of both electrodes is L P (mm), the distance between the tips of both electrodes is A L (mm), the internal volume of the arc tube is V L (cc), the input power is P L (W), and the amount of metal halide enclosed is M (mg). When A L / L P ≦ 0. 4, V L ≦ 1.0,200 ≦ P L / V L ≦ 600, 0.5 ≦ M / Set V L ≤2. |
