A discharge lamp (1) with a discharge vessel (2), which encloses a discharge medium which emits electromagnetic radiation in the VUV range when the lamp is in operation, has a yellow phosphor layer facing the discharge medium on the inside of the discharge vessel wall and a blue layer underneath. phosphor layer. Compared to a conventional three-band phosphor mixture, this results in a higher luminous flux and a lower color locus shift. |
