    摘要: An electronic ballast is provided for adjustable filament preheating of a discharge lamp based on output current symmetry. A power converter receives DC power and outputs AC power. A starting circuit generates a high voltage for starting the lamp. A control circuit controls the AC power output from the power converting circuit. A symmetry determining circuit determines a positive-negative symmetrical state of the AC power output to the lamp with respect to ground. After lamp startup, the control circuit enters a filament heating operation in which the output frequency of the power converting circuit is controlled to a first frequency. At one or more predetermined current detection points during the filament heating operation, the control circuit checks the symmetry state. If the output current is symmetrical at the current detection point, the control circuit ends the frequency heating operation and enters steady state operation with an output frequency of the power converter controlled to a second frequency for maintaining lamp lighting. If the output current is asymmetrical at the current detection point, the control circuit increases the output current to the lamp and continues the frequency heating operation.

    摘要: A high pressure discharge lamp lighting device in this invention comprises a converter, an inverter, an igniter, a controller, and a pulse voltage detection circuit. The converter outputs the direct current voltage. The inverter converts the direct current voltage into the lighting voltage which is alternating current voltage, and applies the lighting voltage to the high pressure discharge lamp through an output terminal. The igniter is configured to output the pulse voltage superimposed on the lighting voltage, whereby the starting voltage is applied to the high pressure discharge lamp. The controller is configured to control the igniter to allow the igniter to superimpose the pulse voltage on the lighting voltage. The pulse voltage detection circuit detects the starting voltage to output the detection signal. The starting voltage regulation circuit regulates the starting voltage to the desired voltage value of the voltage on the basis of the detection signal.

    摘要: A device includes a direct current power circuit configured to convert an alternating current voltage from an alternating current power source into a direct current voltage, an output unit configured to convert a direct current from the direct current power circuit into a square wave alternating current whose polarity is inverted at a prescribed frequency and to supply the square wave alternating current to a high-pressure discharge lamp, a controller, and an anomaly detector configured to detect an instantaneous voltage drop of the alternating current power source. When the anomaly detector detects the instantaneous voltage drop, the controller switches from a normal lighting mode of controlling the output unit to supply the high-pressure discharge lamp with a square wave alternating current to a lighting maintained mode of controlling the output unit to supply the high-pressure discharge lamp with a square wave alternating current having a lower frequency than the square wave alternating current in the normal lighting mode. In this way, it is possible to maintain lighting of the high-pressure discharge lamp even upon occurrence of an instantaneous power failure, an instantaneous voltage drop, and the like.
