Power transformation apparatus, illuminating lamp, and lamp tube using the same

摘要

A power transformation apparatus between DC light element and ballast is provided, including: a first inductance, a second inductance, and a rectifier module. The first inductance includes a first input end and a second input terminal, and at least one of the first input terminal and the second input terminal is electrically connected to an output terminal of the ballast. The second inductance has a third input terminal and a fourth input terminal, and at least one of the third input terminal and the fourth input terminal is electrically connected to another output end of the ballast. The rectifier module has two input terminals, and the two input terminals are electrically connected to the first inductance and the second inductance, respectively. The rectifier module inputs a rectified direct current, so as to provide the electricity to the DC light elements. When the ballast is electrical ballast, the impedance value of the first inductance and the second inductance are between 150Ω and 800Ω.
