Patent ID: 8723433

Claim:
A power transformation apparatus, for being positioned between a DC light element and a ballast, the power transformation apparatus comprising: a first fluorescent emulation module, having two input current terminals, for respectively electrically connecting an output terminal of a first set of AC output terminals of the ballast; a second fluorescent emulation module; having two input current terminals, for respectively electrically connecting to an output terminal of a second set of AC output terminals of the ballast; and a rectifier module, having two input terminals, the two input terminals are electrically connected respectively to any input current terminal of the first fluorescent emulation module and any input current terminal of the second fluorescent emulation module, and outputting a rectified DC, to supply to the DC light element as a power source; wherein the first fluorescent emulation module and the second fluorescent emulation module, are accomplished by an equivalent circuit simulation for emulating electrical characteristics of a gas-discharge light source, for meeting negative-resistance characteristics of the gas-discharge light source.
