Discharge lamp having two-band phosphor |
摘要 |
A discharge lamp ( 1 ) having a discharge vessel ( 2 ) that surrounds a discharge medium that emits electromagnetic radiation in the VUV region during operation of the lamp, has on the inner side of the discharge vessel wall a yellow phosphor layer facing the discharge medium, and a blue phosphor layer lying therebelow. By contrast with a conventional three-band phosphor mixture, a higher luminous flux and a smaller color locus displacement are thereby achieved.
