摘要： The reliability of the airtight sealed section is improved by providing a metallic or ceramic insertion member at a portion positioned between an electricity introducing member and a narrow tube in the airtight sealed section. The difference between the inner diameter of the narrow tube and the outer diameter of the insertion member is made 0.02 to 0.6 mm. The electricity introducing member is constructed by a halogen-resistant first member and a second member whose coefficient of linear expansion is similar to that of the narrow tube, and the junction of the first member and second member is covered with a halogen-resistant glass sealant. The difference between the insertion length of the second member into the narrow tube and the flow-in length of the glass sealant into the narrow tube is made 1 mm or more.

摘要： A discharge lamp comprises an arc tube 6 made of a translucent ceramic dosed with a metallic halide. The discharge is conducted between electrodes 20 disposed in the arc tube 6. The arc tube 6 comprises a main tube body 11 having a large diameter portion 11A and a small diameter portion 11C, and a narrow tube 12 airtightly fixed to the small diameter portion 11C while penetrating the small diameter portion 11C. In the discharge lamp, supposing that L (mm) is the length of a protrusion from the main tube body of the narrow tube portion 12 and P (W) is the rated power of the discharge lamp, L and P satisfy the relationship (P+268.75)/31.25≦L≦(P+456.25)/31.25 and 200≦P≦450.

摘要： An arc tube (6) of discharge lamp comprises a main tube body (11) of translucent ceramic sealed with a terminal plate (13) at both ends thereof. The main tube body (11) comprises integrally a large diameter portion (11A), a tapered portion (11B) which is disposed at both sides of the large diameter portion (11A) and has a smaller diameter toward the forward end thereof, and a small diameter portion (11C) which is connected to the forward end of the tapered portion (11B). In this arrangement, the discharge lamp can be produced more easily than the conventional structure having a narrow portion integrally formed at both ends of a ceramic tube body, making it possible to drastically reduce cost. Further, since a low temperature zone can be only with difficulty formed inside the arc tube during discharge, the luminous efficiency can be raised.

摘要翻译： 放电灯的电弧管（6）包括在其两端用端子板（13）密封的半透明陶瓷的主管体（11）。 主管体（11）一体地包括大直径部分（11A），锥形部分（11B），其设置在大直径部分（11A）的两侧，并且朝向其前端具有较小的直径， 与锥形部（11B）的前端连接的小直径部（11C）。 在这种布置中，放电灯可以比在陶瓷管体的两端整体形成的狭窄部分的传统结构更容易地制造，从而可以大幅降低成本。 此外，由于在放电期间在电弧管内部难以形成低温区域，所以可以提高发光效率。
