Abstract
(EN)
There is provided a dielectric barrier discharge tube drive circuit for making a glass plate thick enough for obtaining sufficient mechanical strength, making the illumination area comparatively large, driving with a low voltage, and reducing the apparent current. The drive circuit applies a high-frequency power via a reactor (32) to a planar type discharge tube (19). When the discharge tube is ON, there is set a state near to the series resonance between the inductance of the reactor (32) and the electrostatic capacity of the glass plate (11 and 12). Such an inductance value of the reactor (32) is selected that the frequency of the high-frequency power is slightly smaller than the series resonance frequency and the load impedance viewed from an AC source (31) is set to the rated impedance. With this configuration, it is possible to obtain a high light emission efficiency when using Xe (xenon) having no environmental problem.

La présente invention concerne un circuit d'excitation pour tube à décharge à barrière diélectrique utilisé pour fabriquer une plaque de verre suffisamment épaisse pour présenter une résistance mécanique suffisante, rendre la zone d'éclairage comparativement grande, assurer une excitation avec une faible tension et réduire le courant apparent. Le circuit d'excitation applique une puissance haute fréquence via un réacteur (32), sur un tube (19) à décharge du type plan. Lorsque le tube à décharge est activé, son état est proche d'une résonance en série entre l'inductance du réacteur (32) et la capacité électrostatique de la plaque de verre (11 et 12). Une telle valeur d'inductance du réacteur (32) est sélectionnée de telle sorte que la fréquence de la puissance haute fréquence soit légèrement plus faible que la fréquence de résonance en série et que l'impédance de charge vue depuis une source CA (31) soit définie en fonction de l'impédance nominale. Avec cette configuration, il est possible d'obtenir une efficacité élevée d'émission lumineuse lorsqu'on utilise du xénon (Xe) ne présentant pas de danger pour l'environnement.

 ガラス板の十分な機械的強度が得られる程度の厚さにし、照明面積を比較的広くし、低い電圧で駆動し、皮相電流を低減する誘電体バリア放電管駆動回路。駆動回路は、高周波電力をリアクトル(32)を介して平面型放電管(19)に印加する。点灯状態では、リアクトル(32)のインダクタンスとガラス板(11及び12)の静電容量との直列共振に近い状態が設定される。高周波電力の周波数が直列共振周波数よりわずかに小さく、交流源(31)から見た負荷のインピーダンスが定格インピーダンスに設定されるように、リアクトル(32)のインダクタンス値が選定される。この構成では、放電ガスとして環境問題がないXe(キセノン)ガスを用いた場合、高い発光効率が得られる。
