Abstract: PROBLEM TO BE SOLVED: To extend service life of a lamp by raising a temperature of the coolest point, without raising the temperature of the center part of a vessel by providing multiple projections on the surface of a shell part forming a discharge space of the vessel integrally formed by the shell part and a terminal part where an electrode part is inserted. SOLUTION: This emission vessel 1 consists of a bulging shell part 2 and terminal parts formed at both ends opposing to each other to insert an electrode member, and the whole body is formed integrally from aluminum of a translucent ceramics material. Multiple projections 4, having a tip part of a hemispherical shape, are approximately equally formed on a surface of the shell part 2. Surface area of the shell part 2 is increased by forming the projection 4 thereon, and heat release can be increased. The temperature on a pipe wall near the center part of the emission vessel 1 is decreased, and the difference in temperature between the part near the center part and the coolest point is decreased. The temperature of the overall arc tube can be thereby raised, and the temperature on the coolest point can be raised.

Abstract: PROBLEM TO BE SOLVED: To lessen the runoff of the heat while a high pressure discharge lamp is lighted as much as practicable. SOLUTION: A trunk part 1 is formed so that the ratio of its central part B to the inside diameter of the opening part ranges 3.5 to 8, preferably 4 to 7. In this manner, the inside diameter A of the opening part of the trunk 1 is made largely small, compared with the inside diameter B of the central part of the trunk 1, so that the opening part of the trunk 1, i.e., the heat capacity of the end part of trunk, can be lessened when this is used, for example in a metal halide lamp, which allows lessening of the heat running off while high pressure discharge lamp is lighted.

Abstract: PROBLEM TO BE SOLVED: To prevent the shrinkage of the inner diameter of an end section member, improve the fitting strength, and prevent a gas leak from a boundary face by inserting an integral molding or a temporarily baked body of an electrode member insertion portion and a circular portion into the inside of a tube main body portion, baking an assembly to form an integrally baked body, and generating the crimping force from the circular portion to the tube main body portion after baking. SOLUTION: The circular portion 1b of the first molding or its calcinated body 1 is inserted into the inside of each end section 3a of the second molding or its temporarily baked body 3 of a tube main body to form an assembly 5. The outer diameter size of the circular portion 1b when the first molding 1 and the second molding 3 are baked without being assembled is set to 1.001-1.010 times the inner diameter size of the second molding 3 of the tube main body, for example, and the adhesiveness of them is improved. The assembly 5 thus formed is baked, and the inner diameter of the end section member for inserting an electrode member is prevented from being shrunk at the contact portion with the circular member 1b.
