ABSTRACT:
A process is disclosed which prepares a low pressure mercury vapor discharge lamp having a bulb and an end plate connected to the bottom of the bulb. The steps involve the application of an adhesive on one surface of the end plate, and the subsequent insertion of an exhaust tube into the end plate in such a way that an enlarged diameter portion of the exhust tube has an adhesive formed on this portion. As a result of the location and the structure of the steps, it is possible to provide a single step method of heating which functions to perform the essential bonding of all parts.
