Discharge lamp lighting device, headlight device and vehicle having the same |
摘要 |
A discharge lamp lighting device includes: a DC power source; an inverter for inverting the DC power at a predetermined inversion time interval to supply a square wave AC power to a discharge lamp; and a controller for controlling the output power. The controller performs a synchronous operation and controls the DC power source such that DC power outputted during a period other than the output temporarily increasing period in a power increasing period is greater than the DC output power outputted during the period other than the output temporarily increasing period in a rated power period. Further, the controller controls the DC power source such that at least one of an increment of the output power for the output temporarily increasing period and a length of the output temporarily increasing period is less in at least a part of the output increasing period than in the rated power period. |
