    摘要: The present invention provides a high frequency electronic ballast with low voltage output, comprising a high voltage power supply (200) generating high voltage power (234) at a voltage and a frequency; a low voltage microcontroller (214) which is responsive to the voltage and the frequency of the high voltage power (234) and generates a low voltage drive signal (240); and a switch (216) operably connected to the high voltage power supply (200) and responsive to the low voltage drive signal (240). The low voltage output of the switch (216) can be used to drive auxiliary low voltage loads (220), such as a back-up incandescent lamp (116). The low voltage output can be responsive to HID lamp power, so that the back-up incandescent lamp (116) is energized when the HID lamp is not providing illumination.

    摘要: A high frequency electronic ballast for main loads, such as an HID lamp, includes a regulated low voltage output to drive auxiliary loads. A low voltage microcontroller generates a low voltage drive signal in response to voltage and frequency of a high voltage power supply. A switch operably connected to the high voltage power supply and responsive to the low voltage drive signal provides the regulated low voltage output to drive the auxiliary devices, such as a back-up incandescent lamp and/or an insulation detector. In one embodiment, the low voltage output may be responsive to the HID lamp power, e.g., a control signal from a ballast microcontroller, so that the back-up incandescent lamp is energized when the HID lamp is not providing sufficient illumination.
