Abstract
In a known method for operating an amalgam lamp having a nominal power P, it is provided that a lamp voltage Udesigned for a maximum UVC emission is applied between electrodes or a lamp current Idesigned for a maximum UVC emission flows between electrodes. The discharge space is accessible for an amalgam deposit, which is heatable by a heating element in which a heating current Iis conducted through the heating element. Starting from this background, in order to provide an operating mode that ensures a stable operation in the region of the optimum power, it is proposed that a target value of the lamp current Iis set that is less than Iand that the heating current Iis turned on or increased when the lamp current falls below a lower limit Iand is turned off or reduced when it exceeds an upper limit Ifor the lamp current.
