放电灯驱动装置、光源装置、投影仪以及放电灯驱动方法
摘要：
放电灯驱动装置、光源装置、投影仪以及放电灯驱动方法。提供能够与放电灯的个体差异无关地延长放电灯的寿命的放电灯驱动装置。本发明的放电灯驱动装置的一个方式的特征在于，具备：放电灯驱动部，其向具有第1电极和第2电极的放电灯供给驱动电流；控制部，其控制所述放电灯驱动部；以及存储部，其存储所述驱动电流的多个驱动模式，所述多个驱动模式分别具有多个驱动参数，当向所述放电灯供给的驱动电力是规定的功率带且所述放电灯的电极间电压是规定的电压值时，所述控制部执行至少三个所述驱动模式，在所述至少三个驱动模式中的各两个驱动模式之间，所述多个驱动参数中的至少一个所述驱动参数的值互不相同。
摘要（英）：

The invention discloses a discharge lamp drive device, a light source device, a projector and a discharge lamp drive method. The discharge lamp drive device capable of extending the life of a discharge lamp irrespective of individual differences in discharge lamps is provided. According to one embodiment of the invention, the discharge lamp drive device is characterized in that the discharge lampdrive device includes a discharge lamp driver adapted to supply a drive current to a discharge lamp having a first electrode and a second electrode, a control section adapted to control the dischargelamp driver, and a storage section adapted to store a plurality of drive patterns of the drive current. Each of the plurality of drive patterns has a plurality of drive parameters. The control sectionexecutes at least three of the drive patterns in a case in which drive power to be supplied to the discharge lamp is in a predetermined power band, and in a case in which an inter-electrode voltage of the discharge lamp is a predetermined voltage value. Any two of the three drive patterns are different from each other in a value of at least one of the plurality of drive parameters.
