Abstract

To provide a flat discharge lamp lighting system capable of preventing fusion of a dielectric layer and a glass container separating an electrode and a discharge medium due to extreme temperature rise of an electrode part while shortening rise time of luminance in early stages of lighting in the flat discharge lamp of a barrier discharge system. This flat discharge lamp lighting system detects the temperature of the electrodes 6a, 6b of the flat discharge lamp L, and controls to continuously or gradually reduce tube power supplied to the lamp according to the rise of the electrode temperature in start of lighting.
