LIGHT SOURCE DEVICE, METHOD OF DRIVING DISCHARGE LAMP, AND PROJECTOR |
摘要 |
A light source device including a discharge lamp that has a first electrode and a second electrode opposed to each other in a hollow portion in which a discharge medium is enclosed; and a driving device that supplies a driving voltage to the first electrode and the second electrode, wherein the driving voltage is applied to the discharge medium through the first electrode and the second electrode such that the discharge medium emits light, wherein the driving device changes a relative potential of the first electrode with respect to the second electrode at a plurality of frequencies.
