摘要： There is provided a discharge-lamp lighting device that, upon start-up of a high-intensity discharge lamp, alternately outputs a period A during which a starting circuit applies a high voltage to the high-intensity discharge lamp by resonance operation when a DC/AC inverter outputs a high-frequency voltage, and a period B during which the DC/AC inverter applies a low-frequency-square-wave voltage or a DC voltage to the high-intensity discharge lamp via the starting circuit. The period A for applying the high voltage by the resonance operation is set to about a time enough for a high-intensity discharge lamp in an initial aging stage to cause a dielectric breakdown, and a period C for alternately outputting the high-voltage generating period A and the period B for outputting the low-frequency-square-wave voltage or the DC voltage is set to about a time enough for a high-intensity discharge lamp in a life's last stage to cause a dielectric breakdown.

摘要： An electronic ballast is provided for quickly restarting a high-pressure discharge lamp after shutdown. The ballast includes a power supply circuit for supplying power to the lamp from a commercial power source, a start voltage generation circuit for supplying a starting high voltage to the lamp and a control circuit for controlling the power supply circuit and the start voltage generation circuit. A lighting transition module detects a startup or shutdown of the lamp. A lighting time count module measures a lighting time of the lamp when startup is detected. A comparison module compares the lighting time and a first reference time when shutdown is detected. A delay time setting module sets a predetermined delay time of the start voltage generation circuit based on the comparison result. Operation of the ballast is halted from a startup trigger until lapse of the delay time, and then the high starting voltage is supplied to the lamp.

摘要： A high-pressure discharge lamp ballast is provided for igniting and re-igniting a high-pressure discharge lamp in various states of operation. A power supply circuit is coupled to a power source and supplies AC power to the lamp. An ignition voltage generating circuit supplies a high-voltage ignition pulse for igniting the lamp. A pulse control circuit alternatively controls the ignition voltage generating circuit in a first control mode to provide the high-voltage ignition pulses for a first time period and in a second control mode to delay the high-voltage ignition pulses for a second time period. An abnormality detection circuit detects an abnormal lighting state of the lamp wherein a measured condition of the lamp corresponds to a predetermined condition. The pulse control circuit increases a ratio of the second time period relative to the first time period upon detection of an abnormal lighting state of the lamp by the abnormality detection circuit.
