Abstract

In this work, to improve the luminance efficiency of the lamp, xenon dielectric barrier discharge flat lamps (DFLs) with new electrode structures were fabricated and electric-optical characteristics were analyzed in respect with various discharge conditions. The luminance efficiency increased as the increasing of the capacitance and the reducing of the dielectric loss, and as the improvement in the transmittance of the generated visible light at the discharge space. The luminance efficiency of the DFL with Al₂O₃ dielectric layer of 60-μm thickness, matrix shape electrodes and discharge space of 1-mm gap-width was obtained as 26.3 lm/W and the luminance was 4 873 cd/m².
