Latest Patents

Toshiki Takagi holds a patent for a "Discharge lamp lighting control apparatus and lamp current supply method." This invention realizes a constant-current control even in a stable state of a lamp without increasing the rated output of a power supply. In a stable state of the lamp, where the change value of lamp voltage after the discharge lamp is turned on becomes less than a certain value, the apparatus changes a current command value to perform constant-current control as the lamp voltage rises. This process involves transitioning from a first current command value at the time of lamp activation to a second current command value that is smaller by a predetermined value. The constant-current control is then performed using this second command value, which is further adjusted downward with each increase in lamp voltage.
