Abstract

PURPOSE:To achieve sufficient strength against the stress perpendicular with the lamp axis, by limiting the fitting dimension between the outer tube sealing section of a lamp and the base which is screwed into said sealing section in specific range. CONSTITUTION:A screw is formed on the outercircumferential face of the sealing section of an outer tube for the purpose to be fitted into the screw groove of a base 2. The fitting dimension (a) between said sealing section 9 and the base 2 is limited in the range of 15-18mm.. Consequently it can withstand 3NM moment specified in JIS, while furthermore it can withstand siffuciently even if the stress from the direction perpendicular to the lamp axis is 4-6kg, for example, and the strength against the stress in the direction perpendicular to the lamp axis can be made two times that of conventional one.
