DIMMABLE AMALGAM LAMP AND METHOD FOR OPERATING THE AMALGAM LAMP WHILE DIMMED

DIMMABLE AMALGAM LAMP AND METHOD FOR OPERATING THE AMALGAM LAMP WHILE DIMMED

A dimmable amalgam lamp is provided having a quartz glass tube enclosing a discharge chamber comprising a filling gas, and closed by pinching at both ends thereof, through which at least one current feedthrough is fed through one coil-shaped electrode each in the discharge chamber, wherein at least...

description A dimmable amalgam lamp is provided having a quartz glass tube enclosing a discharge chamber comprising a filling gas, and closed by pinching at both ends thereof, through which at least one current feedthrough is fed through one coil-shaped electrode each in the discharge chamber, wherein at least one of the pinches has a hollow space having an opening to the discharge chamber for receiving a deposit of amalgam that can be heated by the coil-shaped electrode. In order to provide a method for operating the amalgam lamp on this basis, ensuring a high efficiency of UV-C radiation even when dimmed, the invention proposes that the current feedthrough include an outgoing line and a return line for an additional current Iadd, and that the additional current Iadd is adjusted as a function of the level of the actual lamp current Iactual.
