| titleOfInvention | High pressure metal vapor discharge lamp |
| abstract | (57) [Problem] To provide a ceramic arc tube having a tapered portion, A high-pressure metal vapor discharge lamp capable of reducing a change in characteristics with respect to a change in lighting direction is obtained. SOLUTION: A first cylindrical portion 11 and the first cylindrical portion 11 are provided. And a second cylindrical portion 17a, 17b smaller than the inner diameter of the first cylindrical portion 11 at one end of each tapered portion 12. Arc tube 1 An arc tube 1 made of ceramic has electrode shafts 14a and 14b fixed to second cylindrical portions 17a and 17b such that the electrode coils 13a and 13b are located inside. Arc tube 1 The angle α between the surface of the inner tapered portion 12 and the electrode shafts 14a and 14b is 50 to 80 degrees, and the length L (mm) of the first cylindrical portion 11 with respect to the inner diameter D (mm) of the first cylindrical portion 11 Is -0.014α + 1.4 ≦ (D / L) ≦ 0.01 7α + 0.36. |
