Abstract
System and method for igniting one or more high-intensity-discharge lamps. A system includes an ignition controller configured to generate one or more signal pulses for a pulse signal during a first predetermined time period and to cause one or more voltage pulses to be applied to the one or more high-intensity-discharge lamps, the pulse signal changing between a first logic level and a second logic level during the first predetermined time period, each of the one or more signal pulses corresponding to a pulse period, the pulse period being no larger than the first predetermined time period. The ignition controller is further configured to, if the one or more high-intensity-discharge lamps are not successfully ignited after the first predetermined time period, stop generating any signal pulse for the pulse signal for a second predetermined time period, the second predetermined time period being equal to or larger than the pulse period.
