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： An arc tube and method for forming an arc tube in which an electrode assembly including a tungsten electrode and a molybdenum foil are joined together in a partially overlapped state and pinch sealed into a pinch seal portion of the arc tube body to suppress leakage due to peeling of the molybdenum foil and prolong the life period of the arc tube. An overlapped length L1 of a tungsten electrode 26 and a molybdenum foil 30 is set to be 2DnullL1null0.8 W with respect to the diameter D of the tungsten electrode 26 and the width W of the molybdenum foil 30, whereby occurrence of peeling of the molybdenum foil 30 is effectively suppressed while effectively suppressing occurrence of breakage of the molybdenum foil 30. In another embodiment, the distance L2 between the molybdenum foil 30 and a discharge space 24 is set to be BnullL2null0.8 A with respect to the width A and the thickness B of a pinch seal portion, whereby occurrence of peeling of the molybdenum foil 30 is effectively suppressed while effectively suppressing growth of electrode cracking.

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.
