摘要： A method of manufacturing an arc tube having a light emitting tube portion, a first pinch seal portion, and a second pinch seal portion, all formed on a quartz glass tube. The first and second pinch seal portions are disposed on both sides of the light emitting tube portion. The quartz glass is provided almost vertically with the first pinch seal portion down. A thermal insulating plate is provided in a boundary position between the light emitting tube portion and a portion to be pinch-sealed in an outer peripheral space of the quartz glass tube. Liquid nitrogen is jetted from a cooling nozzle provided obliquely below the light emitting tube portion toward the same, thereby cooling the light emitting tube portion. The portion to be pinch-sealed is heated with a burner, and pinch-sealed with a pincher immediately thereafter.

摘要： An arc tube body 20 and a foil such as molybdenum foil 30 are joined with each other such that a compressive stress of 105 N/m2 or more remains at an ordinary temperature in the arc tube body 20 along a junction surface. The compressive stress is always generated on the arc tube body 20 even if a fluctuation in the stress is caused on the junction surface by the repetition of the ON/OFF of the arc tube (or a tensile stress is caused to have a very small value even if the compressive stress and the tensile stress are alternately generated). Thus, the junction strength of both members may be increased. In one embodiment, a plurality of cracks (intercrystalline cracks) may be generated on the molybdenum foil 30 by a high pressure acting during pinch seal, and quartz glass is caused to enter the cracks so that the junction strength of both members can be increased.

摘要： An arc tube that effectively prevents a metal halide from being deposited in a light emitting tube portion, causing the change of a light emitting color or the generation of lighting failures in an arc tube. An axial distance L1 from a neck portion 20C of an arc tube body formed between a light emitting tube portion 20A and a pinch seal portion 24B of the arc tube body to a step-down plane portion 20Ba2 of each pinch seal surface 20Ba in a pinch seal portion 20B is set to 1 mm or less. During pinch seal, consequently, a sufficient pinching pressure is applied to a electrode 26, such as a tungsten electrode up to a portion close to a tip portion thereof. Thus, it is possible to reduce the volume of an almost wedge-shaped slit 24a formed around the tungsten electrode 26 on an end in the axial direction of a discharge space 24, thereby decreasing the amount of a metal halide deposited on the slit 24a.

摘要： A method for manufacturing an arc tube which obtains a high luminous flux retention rate by completely removing impurities, such as oxides, from the surfaces of the electrodes within the arc tube. An exhaust tube is connected to a glass tube of an arc tube in which a pair of electrodes are oppositely disposed. After gas is exhausted through the exhaust tube from the glass tube, inert gas is introduced. An arc discharge generating circuit is connected to the oppositely disposed electrodes, and an ion bombardment process is carried out in which an arc discharge is caused between the electrodes in the inert gas atmosphere at a current density of 30 to 100 A/mm.sup.2. Due to the arc discharge process, impurities (oxides), which lead to a reduction of the luminous flux retention rate, are completely removed from the electrode surfaces. Gas is exhausted from the glass tube, and then a degassing process is carried out to degas the glass tube while it is heated to thus completely remove impurities from the inner wall of the glass tube. Metal halide as a luminous material, mercury, and a rare gas are successively introduced into the glass tube through the exhaust tube, and the exhaust tube is tipped off.
