| 摘要 | A discharge lamp driving device according to an aspect includes: a discharge lamp driving section configured to supply driving power to a discharge lamp including electrodes and a control section configured to control the discharge lamp driving section. The control section is configured to perform a steady lighting driving for supplying first driving power to the discharge lamp and a high power driving for supplying second driving power larger than the first driving power to the discharge lamp. The magnitude of heat load on the electrodes by the high power driving changes on the basis of the first driving power. | ||
