Claims7
A method for producing a discharge lamp, having the steps:
- assembling an open discharge vessel (2, 3, 16) of the discharge lamp and filling it with a first gas in an environment (1) of the first gas,
- adding a second gas to the first gas in the assembled discharge vessel (3), using a supply volume (12, 15) separate from the environment of the discharge vessel (3) and wherein the assembly and filing of the discharge vessel (2, 3, 16) with the first gas are carried out in a continuous furnace (1)
- characterized in that a spectral analysis of the first gas in the discharge vessel (3, 16) is carried out after closing the discharge vessel (3, 16) and before introducing the second gas.
