PURPOSE:To provide an electric discharge lamp lighting device wherein the necessity for a signal wire except a power feed wire between an inverter and an igniter is eliminated and further an influence by a temperature of an HID lamp can be corrected. CONSTITUTION:In a constitution, a temperature sensing element 4 is arranged in the vicinity of an HID lamp (high intensity high pressure electric discharge lamp) 1, and by changing the condition of an igniter 2 by this temperature sensing element 4, a supply amount of power to the HID lamp 1 from an inverter 3 is adjusted. In this way, without providing a separate signal wire except a power wire from the inverter 3, temperature correction of a rise characteristic of the HID lamp 1 can be performed. |
