  • Patent number: 9474139
    Abstract: High frequency ballasts are provided herein for ignition control of a ceramic high intensity discharge (HID) lamp. A sensor senses a lamp parameter on the output terminals. A microprocessor is attached to the ignition circuit and the sensor. The ignition circuit is configured by the microprocessor to apply a train of pre-ignition bursts to the electrodes and stop the train of pre-ignition bursts responsive to measurement of the lamp parameter. The measured lamp parameter is indicative of a stable arc at the proximal ends of the capillaries.

  • Patent number: 9095034
    Abstract: A method for ignition of a ceramic high intensity discharge (HID) lamp. The method includes applying to the electrodes multiple pre-ignition voltage pulses of sufficiently short duration to avoid igniting the HID lamp. The pre-ignition voltage pulses heat the electrodes prior to ignition to avoid arcing in the bores of the capillaries surrounding the electrodes. The ignition circuit is configured subsequent to application of the pre-ignition voltage pulses to apply an ignition pulse to ignite the HID lamp.
