Patent ID: 7345423

Claim:
An assembly of an elongate low-pressure mercury vapor discharge lamp ( 1 ) and at least one elongate extension means ( 2 ), the low-pressure mercury vapor discharge lamp comprising: a light-transmitting discharge vessel ( 10 ) enclosing, in a gastight manner, a discharge space ( 15 ) provided with a filling of mercury and a rare gas mixture, the rare gas mixture comprising at least 50% by volume of krypton, the gas pressure in the discharge vessel ( 10 ) being greater than 1·10 5 Pa, the discharge vessel ( 10 ) being provided with a luminescent layer ( 13 ), electrodes ( 4 a ; 4 b ) being arranged in the discharge space ( 15 ) for maintaining a discharge in the discharge space ( 15 ), the elongate extension means ( 2 ) being provided for connection to the low-pressure mercury vapor discharge lamp ( 1 ), the extension means ( 2 ) comprising an inductance ( 3 ), the length of the low-pressure mercury vapor discharge lamp ( 1 ) together with the length of the extension means ( 2 ) being adapted to fit a pre-determined mounting distance l md of low-pressure mercury vapor discharge lamps.
