DISCHARGE LAMP LIGHTING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a discharge lamp lighting equipment inhibiting a phenomenon in which a desired dimmer light level is obtained after becoming bright at once, at the time of starting in the dimmer state. SOLUTION: A control section 12 makes an impedance element Z2 conducted by detecting a lighting of an electric discharge lamp La by a detection output of an electric discharge lamp lighting detector circuit 30, and supplies a direct- current electric power to the electric discharge lamp La from a direct current power source 11.
