PURPOSE:To obtain an electronic lighting device for rectangular-wave lighting a high-output ultraviolet radiation discharge lamp, which needs a high lighting voltage. CONSTITUTION:Each pair of IGBT 11, IGBT 12 and IGBT 13, IGBT 14 and IGBT 15, IGBT 16 and IGBT 17, IGBT 18 connected in series to each other is used as each polarity switching element, and they are connected in a full- bridge shape to form a full-bridge inverter 21. High tension direct current voltage is applied to this full-bridge inverter 21, and an ultraviolet discharge lamp 23 is connected to an output end of this inverter 21 to form an electronic lighting device for ultraviolet radiation discharge lamp. |
