Title:
低電圧出力付き電子安定器
Document Type and Number:
Japanese Patent JP2005514688
Kind Code:
A
Abstract:
The present invention provides a high frequency electronic ballast with ignition and operation control, and method of use, comprising a ballast microcontroller ( 200 ) responsive to at least one high intensity discharge (HID) lamp feedback signal and generating an HID lamp control signal; a parallel capacitive circuit ( 214 ) operably connected parallel to the HID lamp ( 216 ); an inductive circuit ( 212 ) operably connected to the parallel capacitive circuit ( 214 ); means for switching power ( 252 ) to the inductive circuit ( 212 ) in response to the HID lamp control signal; and means for monitoring the HID lamp ( 216 ) 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 ( 266 ). In another embodiment, the HID lamp feedback signal can be a sensed rail voltage signal ( 256 ), a sensed lamp current signal ( 264 ), and a sensed lamp power signal ( 258 ).
