Summary:Disclosed in the utility model is an energy-saving lamp circuit with the characteristic of brightness adjustability. The circuit not only can be used for providing power for a direct-current lamp but also can be used for providing power for an alternating-current lamp. According to the technical scheme, firing angles of two anti-parallel thyristors in a thyristor controlled reactor are adjusted to realize continuous control of voltages of a direct-current lamp and an alternating-current lamp, thereby realizing continuous adjustment of brightness, convenience and high efficiency. Because the thyristor controlled reactor does not consume the active electric energy, power wasting can be avoided in the circuit and the economy of the circuit is good.
