Title:
DIELECTRIC BARRIER DISCHARGE LAMP IGNITION DEVICE, METHOD OF DETECTING NUMBER OF IGNITING DISCHARGE LAMPS
Document Type and Number:
WIPO Patent Application WO/2007/125704
Kind Code:
A1
Abstract:
A dielectric barrier discharge lamp ignition device in which one ignition circuit carries
out parallel ignition of a plurality of dielectric barrier discharge lamps is
comprised of twenty four dielectric discharge lamps (1) and an ignition circuit
(2) for carrying out parallel ignition of twenty four dielectric discharge lamps
(1), which is provided with a direct current power source (3), an inverter circuit
(4), a step-up transformer (5) and a detecting circuit (6) for detecting the number
of igniting lamps. The detecting circuit (6) detects the number of dielectric
discharge lamps that have been normally igniting since the application of a first
peak value right after a positive or negative polarity of a high rectangular voltage
output from the step-up transformer (5) is reversed, and stops the operation of
the ignition circuit (2) if the detected one is equal to a predetermined number or
less.
