摘要
Lighting of a discharge lamp is controlled in a manner to reduce deterioration of the discharge lamp subjected to high temperature and extend the lifetime of the discharge lamp. A method for controlling lighting of the discharge lamp includes a first constant current control process (period T1, which corresponds to steps S3 and S4) in which constant current control is executed by supplying a first current to the discharge lamp, a second constant current control process (period T3, which corresponds to steps S7 and S8) in which constant current control is executed by supplying a second current greater than the first current to the discharge lamp after the first constant current control process, and a constant power control process (period T4) in which constant power control is executed after the second constant current control process.
