摘要：The invention relates to a high-pressure sodium discharge lamp (1) withevacuated outer envelope (3) for operation at low frequency, in particular for higherbrightness at a color temperature between 1800 and 2250 K. The higher brightness canbe achieved by a wall loading higher than 24 w/cm², which wall loading value can be
permitted if the ratio of the discharge gap to the discharge tube inner diameter D/d isless than 5.0.
