Title:
MULTUPLE-LIGHT DISCHARGE LAMP LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/068055
Kind Code:
A1
Abstract:
A multiple-light discharge lamp lighting device in which each of the tube currents of a plurality of discharge lamps can be stabilized and equalized at a low cost without providing a ballast element on the secondary side of an inverter transformer. The discharge lamp lighting device (10) comprises an inverter means (12) and a plurality of inverter transformers TR1-TRn having secondary windings Ns1-Nsn connected with discharge lamps La1-Lan, respectively. Furthermore, variable impedance elements Z1-Zn, preferably variable inductance elements, are connected in series with the primary windings Np1-Npn of the plurality of inverter transformers TR1-TRn and thereby each tube current can be stabilized and equalized without using a high withstand voltage element.
