    摘要: A method and device for arc straightening in an HID lamp, the method comprising the steps of: determining and selecting a frequency signal or a frequency sweep signal that produces arc straightening for an HID lamp; and exciting an arc straightening acoustic mode in conjunction with a carrier frequency signal. In a preferred embodiment, the exciting step comprises amplitude modulating the carrier frequency signal with either the frequency signal or the frequency sweep signal which corresponds to the power frequencies for arc straightening. In a further embodiment, the exciting step comprises summing the carrier frequency signal with a second frequency signal or second frequency sweep signal to obtain a difference power frequency or power frequencies which excite an arc straightening acoustic mode.

    摘要: Power source systems implementing methods for reducing vertical segregation (color mixing) in a long and thin high intensity discharge lamp are disclosed. Each system provides a current frequency signal to the lamp that excites an azimuthal acoustic and longitudinal acoustic combination mode of the lamp whereby color mixing within the lamp can be achieved. Each system further adjusts the current frequency signal as needed to stabilize color mixing within the lamp.
