  • HID lamp ignitor-timer with automatic reset for dips in line voltage
    Patent number: 5424617
    Abstract: A high intensity discharge ballast having an ignitor which shuts off after a predetermined time period has elapsed. The ballast is sensitive to voltage dips in power line voltage and resets a timer whenever the power line voltage drops below a level sufficient for lighting a lamp load. Restart of the lamp load immediately following restoration of power line voltage is achieved without requiring that the power line voltage be removed from the ballast or otherwise reduced to approximately 0 volts before restart can be initiated.
