摘要： A discharge tube is provided inside an outer tube. At least a pair of electrodes is arranged inside the discharge tube, and at least mercury is sealed into the discharge tube. The electrode includes an electrode pin and a metal pipe that surrounds the electrode pin. Because a contact area of the electrode pin and the inner surface of the metal pipe is sufficiently maintained in a stable manner, a tip temperature of the electrode pin can be lowered sufficiently without a variation. As a result, it is possible to obtain a high pressure discharge lamp that has excellent lifetime characteristics and can considerably reduce the variation of the lifetime characteristics between lamps.

摘要： A metal vapor discharge lamp comprises a discharge tube having a ceramic container into which a pair of electrodes and a discharge metal compound are sealed. The container comprises a first cylindrical portion, tapered portions, second cylindrical portions and third cylindrical portions. The third cylindrical portions are shrinkage-fitted to the second cylindrical portions. The electrodes are attached to the third cylindrical portion with a sealing member. An inner wall of the third cylindrical portions and the electrodes define a gap. The inner surface of the tapered portions and a central axis of the electrodes define an angle of 40°-80°. Thus, a metal vapor discharge lamp is provided whose discharge tube does not include disks among its parts, and which can maintain, over a long period of operation, good operating characteristics that depend only little on the lamp orientation.

Thus, a metal halide lamp can be obtained that has a stable lifetime and considerably increased lamp efficiency compared to conventional high-color-rendition high-performance metal halide lamps using a quartz discharge tube.

摘要： A discharge tube (1) made of transparent ceramics includes a main tube (17) and slender tubes provided on both sides thereof. In one of the slender tubes, a main electrode lead-in member that is connected to a main electrode (6b) is inserted and sealed. In the other two-hole slender tube, a main electrode lead-in member that is connected to a main electrode (6a) and an auxiliary electrode lead-in member that is connected to an auxiliary electrode (9) are inserted and sealed so as to be isolated electrically from each other. With such a structure, it is possible to achieve highly efficient and stable lifetime characteristics and suppress changes in characteristics during lifetime caused by leaks during an operation and reaction between a sealing material and an enclosed material inside the discharge tube. In addition, it is possible to obtain a high-pressure metal vapor discharge lamp that has stable lamp starting characteristics and allows a free design of the discharge tube.

The rod of at least one of the electrodes is held by a tubular electrode holder made of a halide-resistant metal embedded in and bonded to the thin-tube part via an adhesive agent including a sintered halide-resistant metal impregnated with mixture glass. The electrode holder is at such a position that satisfies “L≧0.012P+2.5 [mm]”, where “L” is distance [mm] between the electrode top and one end of the electrode holder closer to the discharge space, and “P” is lamp wattage [W].
