Title
(EN) DIELECTRIC BARRIER DISCHARGE LAMP OPERATING DEVICE
(FR) DISPOSITIF DE FONCTIONNEMENT D'UNE LAMPE A DECHARGE A BARRIERE DIELECTRIQUE
Abstract
(EN) Luminance gradient between electrodes is prevented by decreasing the leakage current of a dielectric barrier discharge lamp. Electrodes (3, 4) are provided on the outer surface of the dielectric barrier discharge lamp (1). The electrodes (3, 4) are connected to the high−voltage sides of high−frequency power supplies (5, 6), respectively. The low−voltage sides of the high−frequency power supplies (5, 6) are connected to the ground voltage GND. The phases of the output voltage waveforms of the high−frequency power supplies (5, 6) are different from each other, or the polarities of them are opposite to each other.
(FR) Selon la présente invention, le gradient de luminance entre les électrodes peut être évité par la réduction du courant de fuite d'une lampe à décharge à barrière diélectrique. Les électrodes (3, 4) sont disposées sur la surface externe de la lampe (1) à décharge à barrière diélectrique. Ces électrodes (3, 4) sont connectées aux bornes haute tension de blocs (5, 6) d'alimentation haute fréquence, respectivement. Les bornes basse tension des blocs d'alimentation (5, 6) haute fréquence sont connectées à la mise à la terre (GND). Les phases des formes d'ondes de tension de sortie des blocs d'alimentation (5, 6) haute fréquence diffèrent les unes des autres, ou leurs polarités sont opposées.
