METHOD AND APPARATUS OF CONTROLLING DISCHARGE LAMP AND DISCHARGE LAMP SYSTEM |
摘要 |
A method and a device for controlling a discharge Lamp, and a discharge lamp system are disclosed herein. The method includes the operations of: when the lamp current changes, determining a percentage of change of the lamp current according to a synchronous signal and obtaining a second lamp current after a discharge lamp current changes according to the percentage of change of the lamp current and a first lamp current; obtaining a modulating signal according to a current difference between the first lamp current and the second lamp current; and generating a pulse voltage signal according to the modulating signal. The pulse voltage signal transits from a first voltage to a second voltage during the time period when the lamp current is transited from a first lamp current to a second lamp current during a transition time.
