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.

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.

摘要： A metal halide lamp has an arc tube including an envelope as an arc tube container made of an oxide-based translucent ceramic material, and the arc tube is filled with luminescent materials comprising at least a cerium halide, a sodium halide, a thallium halide and an indium halide. An amount of the cerium halide is in a range from 20 wt % to 69.0 wt %, an amount of the sodium halide is in a range from 30 wt % to 79.0 wt %, and a total amount of the thallium halide and the indium halide is in a range from 1.0 wt % to 20 wt % with respect to the entire metal halides. Accordingly, the arc discharge is spread, bending of the arc discharge toward the arc tube wall is suppressed, and thus, the metal halide lamp has improved luminescent efficiency, where lowering of the flux maintenance factor is suppressed even after a long-time use, and hues of the luminescent colors are corrected.

摘要： A metal halide lamp has an arc tube including an arc tube container made of an oxide-based translucent ceramic material. The arc tube is filled with cerium halide as a luminescent material and a halide of a rare earth element that is more reactive with the ceramic material than is the cerium halide. Accordingly, a reaction between the oxide-based translucent ceramic material and the halide of a rare earth element is accelerated while a reaction between the oxide-based translucent ceramic material and the cerium halide is suppressed. This suppresses a decrease of the cerium halide that serves for light emission, and also reduces changes in the lamp color temperature. Thereby, during aging of the lamp, the flux maintenance factor and color temperature are improved. Therefore, the indoor-outdoor metal halide lamp provides a white light source color that has high-wattage, high luminous efficiency, and a long service life.
