Power Transformation Apparatus, Illuminating Lamp, and Lamp Tube Using the Same

An illuminating lamp is electrically connected an alternating current, the illuminating lamp comprising:

• at least one DC light element;
• a ballast, one input terminal of the ballast connected to the alternating current;
• and
• a power transformation apparatus between the DC light element and the ballast comprising:
• a first inductance including a first input terminal and a second input terminal, wherein at least one of the first input terminal and the second input terminal is electrically connected to an output terminal of the ballast;
• a second inductance including a third input terminal and a fourth input terminal, wherein at least one of the third input terminal and the fourth input terminal is electrically connected to another output terminal of the ballast;
• and
• a rectifier module including a first rectifier input terminal and a second rectifier input terminal, wherein the first rectifier input terminal is electrically connected to the first inductance and the second rectifier input terminal is electrically connected to the second inductance, and the rectifier module provides a direct current to the DC light element;
• wherein when the ballast is an electrical ballast, an impedance value of the first inductance and an impedance value the second inductance are between 150Ω and 800Ω.

A lamp tube comprising:
