SILICA PREVENTING METHOD OF AN UHP LAMP, CAPABLE OF EXTENDING THE LIFESPAN BY IMPROVING A MANUFACTURING PROCESS

摘要

PURPOSE: A silica preventing method of an UHP lamp is provided to extend the life expectancy and prevent the silica by improving a manufacturing process without lowering a tube wall load.;CONSTITUTION: A first electrode and a second electrode are simultaneously inserted into. A first sealing is executed, and a vacuum heat process is executed. A room temperature cooling is executed, and the argon is filled over the atmospheric pressure. A vacuum path is opened. An arc tube in a vacuum path is moved to a Globe Box within a short time as possible. The argon is filled with. The mercury and compound are inserted into the inside the Globe Box, the arc tube is installed to the discharge part which is attached to the Globe Box, and the discharge is executed.;COPYRIGHT KIPO 2010
