Sealing of second side of ceramic gas discharge high pressure lamps - having sealed chambers supplied with gas for filling tubes with air excluded and followed by evaluation process

摘要

During a production process for high pressure gas discharge lamps cleaning and sealing chambers are positioned (6,7) at locations on an indexing machine. The chambers are identical and have valve (13-16) controlled lines coupled to connection ports. A rotary magazine (5) provides components for the discharge tubes (8) that are inserted into heater stages (11). The lower section of the chambers are sealed (12) and in the case of the sealing chamber the appropriate valves can be opened to admit gas and the end of the discharge tube is sealed. At the same time the cleaning chamber is performing. ADVANTAGE - Reliable sealing of second side of ceramic discharge lamp chambers.
