It is part continuation application of the 09/800,669th number where is transferred main application of the HID lamp, the arc tube and those production mannered-related applications receives and this invention vis-a-vis the person, is submitted on 2001 March 8th.

摘要

It is the arc tube and the production manner for the HID lamp, it features that it can the restoration gas pressure to exceed the atmospheric pressure which is in abbreviation room temperature, without in the step sealing the arc tube isolating inside the arc tube from the natural atmosphere. The restoration gas pressure to exceed this atmospheric pressure can by controlling the temperature of the restoration gas in the step sealing the arc tube. With this new arc tube and the production manner, the necessity which runs a some step with human institute of technology air and the necessity which uses the pump in order to control restoration gas pressure are cancelled.
