Optimization of Xenon Gas Discharge Flat Panel Lamps

Abstract

A xenon gas discharge flat panel lamp is made and the influence factors: the gas pressures, the gas compositions and gas gap on the luminous efficacy of the xenon gas discharge flat panel lamps were investigated. Marked increments of the luminous efficacy of the lamps were observed by optimizing the structures and the discharge conditions. The results showed that the xenon gas discharge flat panel lamps with a luminance of above10,000 cd/m2, a luminous flux of above 450 lm, a size of 126×87 mm and an luminous efficacy of about 43 lm/W could be attained at about 450 torr xenon, 0.71 mm gap distance and 2.8 mm front glass layer thickness. The factors which influenced the luminous efficacy were discussed in the end.
