Abstract

A multi-lamp driving system for driving a first lamp and a second lamp includes a power supply circuit, and first-stage transformers. The power supply circuit is used for supplying the first and second lamps with an AC power, and first-stage transformers coupled to the power supply circuit for performing an impedance-matching function to balance lamp currents and deliver evenly distributed current to each lamp in the multi-lamp system so that each lamp provides approximately same amount of luminance. The first-stage transformers includes a first transformer haye a primary side coupled to the power supply circuit and a secondary side coupled to the first lamp, and a second transformer have a primary side coupled to the first transformer and a secondary side coupled to the second lamp.
