FLUORESCENT LAMPS AND METHOD OF MANUFACTURING THE SAME

摘要

Fluorescent lamps which are manufactured by a process in which the lamp envelope, during one step of the process, is exhausted through both ends simultaneously thereby avoiding unnecessary contamination within the lamp envelope. In a preferred embodiment of the process, the electrodes are activated outside of the lamp and the contaminants removed to prevent them from contaminating the lamp. A lamp is also disclosed in which the end caps have electrical contact members mounted directly thereon through which the lamp is to be connected to a fixture to supply current to the lamp, and in which the mounting leads for the cathode of each end cap are connected directly to these electrical contacts. The end caps are also formed to accept an end of the envelope of a fluorescent lamp for direct attachment thereto. In a further embodiment of the invention an end cap is provided having a tubulation which can be sealed by infra-red energy.
