Abstract
The present invention provides a high frequency electronic ballast with ignition and operation control, and method of use, comprising a ballast microcontroller () responsive to at least one high intensity discharge (HID) lamp feedback signal and generating an HID lamp control signal; a parallel capacitive circuit () operably connected parallel to the HID lamp (); an inductive circuit () operably connected to the parallel capacitive circuit (); means for switching power () to the inductive circuit () in response to the HID lamp control signal; and means for monitoring the HID lamp () to generate at least one high intensity discharge (HID) lamp feedback signal. In one embodiment, the HID lamp feedback signal can be an ignition voltage signal (). In another embodiment, the HID lamp feedback signal can be a sensed rail voltage signal (), a sensed lamp current signal (), and a sensed lamp power signal ().
