Abstract
A system for driving a multi-lamp, and more particularly to, a system for driving a multi-lamp for driving a parallel arrangement of a plurality of discharge lamps and a method of driving a plurality of discharge lamps and a method thereof. The multi-discharge lamp driving system comprises: a power transformer for producing a positive voltage and a negative voltage upon receipt of an alternative power source from an alternative power supply source; and a current balance distributor for being supplied with the positive voltage produced from said power transformer to divide the supplied positive voltage into a plurality of predetermined voltages, and for applying the divided predetermined voltages to the corresponding electrodes of a plurality of discharge lamps consisting of a lamp array for the purpose of distributing an amount of a current flow so that the distributed current flow inputted into each of the plurality of discharge lamps may keep to make a mutual balance from each other, wherein the negative voltage is commonly applied to second electrodes of the plurality of discharge lamps.
