Title:
LOW-PRESSURE ELECTRIC-DISCHARGE LAMP
Document Type and Number:
WIPO Patent Application WO/1985/004048
Kind Code:
A1
Abstract:
A low-pressure electric-discharge lamp is of a double-tube structure in which a gas is sealed into an outer tube of which an end portion is closed, and an inner tube defining an electric discharge path is supported by an end plate so that it can communicate with the inside of the outer tube and has electrodes housed therein. The end portions of the inner tube with the electrodes therein are secured to the end plate by a bonding agent, while part of the inner tube away from the end portions with the electrodes housed therein is adapted to abut against the end plate so as to be supported thereby. Thus it is easy to conduct the operation of securing the inner tube to the end plate. The assembled electric-discharge lamp is lightweight and has an inner tube which is mechanically stable.
