Abstract

The lamp drive circuit at least includes three transformers and two lamps. The first transformer couples with a first end of the first lamp and the second transformer couples with a second end of the first lamp. The first transformer and the second transformer are used for driving the first lamp. The second transformer couples with a first end of the second lamp and the third transformer couples with a second end of the second lamp. The second transformer and the third transformer are used for driving the second lamp. Wherein the second transformer includes a first secondly coil and a second secondly coil. The first secondly coil couples with the second end of the first lamp. The second secondly coil couples with the first end of the second lamp. The number of coil turns of first secondly coil is equal to the number of the second secondly coil substantially.
