1. the operation method of high-voltage lamp resonance operation in vertical pattern, adopt and a kind ofly carry out warbled high frequent carrier frequency by sweep generator, in the scope of the frequency of wherein said sweep signal between described first orientation and radial mode, and carry out simultaneously amplitude modulation, one of them controller is regulated the fundamental frequency of AM, wherein the fundamental frequency of AM is derived by the second vertical pattern, it is characterized in that, carries out successively following three running statuses after lamp is lighted:

  • A) 30 to 150 seconds warm-up phase, by any fundamental frequency fAM of AM, wherein or second vertical resonance f002_hor of selection level burning position as the fundamental frequency of AM, thereby so that fA=f002_hor, thereby perhaps abandon AM so that fAM=0;

    B) apply the stage, be characterized in time dependent and different from the condition of continuous operation AM, this AM has 30% the AM degree that is up to, and wherein fAM is adjusted to 1.15 to 1.25 times the value of frequency f 002_hor, and the rate of change of fAM was 0.5 to 15kHz/ second;

    C) have the continuous operation phase of AM controlled condition, thereby f002_hor wherein is set as the fundamental frequency fAM of described AM so that fAM=f002_hor, and the AM degree is in 20 to 25%.
