Abstract: In a high intensity discharge lamp, at least one of an arc bend amount and an apparent width of arc is controlled by a simple configuration at low cost. A high intensity discharge lamp system 110 has a high intensity discharge lamp 111 and an operating circuit 113 for driving the high intensity discharge lamp 111. In the high intensity discharge lamp 111, a rare gas and a filling material 136 containing a metal halide as a light generating substance are enclosed in the arc tube 121 provided with a pair of electrodes 122a and 122b. The lamp system is disposed such that the line connecting the electrodes 122a and 122b is horizontal, and by applying a magnetic field having a vertical magnetic flux thereto and by varying the frequency of alternating current for driving the high intensity discharge lamp 111, at least one of an arc bend amount and an apparent width of arc can be easily controlled.
