Zusammenfassung:	A high-pressure discharge lamp lighting device is used for projector devices that allow controlling the mean electric power at a desired value with a slow processing speed. A color wheel rotates and disperses the beam from lamp into each of the color components, such that the electric power supplied to the lamp is controlled at different levels for each segment of the color wheel and the power feeding device control part finds the mean electric power by sampling the electric power supplied.
