Abstract
A multiple discharge lamp lighting apparatus includes first and second transformers and a bridge circuit configured such that four branch paths each including a discharge lamp are connected to form a quadrangle with four sides constituted by the four branch paths, wherein one terminals of two secondary windings of the first transformer are connected to two lamp connection points disposed at two diagonally opposing corners of the quadrangle and one terminals of two secondary windings of the second transformer are connected to another two lamp connection points disposed at the remaining two diagonally opposing corners, and wherein output voltages from the first transformer repeat inversion with their respective polarities reversed, thus constituting a first differential voltage output, and output voltages from the second transformer repeat inversion with their polarities reversed at every cycle of the polarity inversion at the first differential voltage output, thus constituting a second differential voltage output.
