  • Patent number: 11265978
    Abstract: Realizing a constant-current control even in a stable state of a lamp without increasing a rated output of a power supply. In a stable state of the lamp in which a change value of a lamp voltage after a discharge lamp is turned on becomes less than a certain value, when the lamp voltage rises, a discharge lamp lighting control apparatus changes a current command value to perform a constant-current control. This change is a change from a first current command value at the time when the discharge lamp is turned on to a second current command value that is smaller than the former by a predetermined value. Using this second current command value, the constant-current control is performed. Even after that, the second current command value is changed to a smaller value every time the lamp voltage rises, and the constant-current control is performed using the second current command value.
