Abstract: A transformer. The transformer includes an iron core, a first bobbin, a second bobbin, a primary coil and a secondary coil. The first bobbin surrounds the iron core, and the second bobbin surrounds the first bobbin. The secondary coil is wound on the second bobbin, and the primary coil comprises a first coil section and a second coil section wound on the first bobbin, wherein the coil winding density of the first coil section exceeds the second coil section.

Abstract: A multi-lamp backlight system. The system comprises a core, a first coil set wrapped around the core, to which a first AC voltage is applied, a second and third coil sets wrapped around the core and respectively disposed on two sides of the first coil set, on which a second and third AC voltage are induced by the first voltage signal applied to the first coil set respectively, wherein the numbers of coils of the second and third coil sets are substantially the same, and first and second lamps are supplied with power by the second and third AC voltages respectively.
