A discharge lamp lighting apparatus and a discharge lamp lighting method, wherein the discharge lamp, that may be lighted in a horizontal arrangement, contains a power source apparatus that lights the discharge lamp, a flex supply unit disposed near the discharge lamp, and a control unit configured to control the flex supply unit. The control unit controls the flex supply unit such that the flex pulls an arc perpendicular to the discharge lamp longitudinal direction at a time of start-up voltage impression. A flux whose density is lower than that at the time of start-up voltage impression is supplied when the discharge lamp reaches a stable state. |
