Abstract

The present application relates to the technical field of circuits. Provided are a power carrier circuit and a lighting device. A carrier modulates a carrier signal into an alternating current of a first power source line, so as to obtain an alternating-current carrier control signal; a rectifier converts into a direct current the alternating-current carrier control signal transmitted by the first power source line, so as to obtain a first direct-current signal; a first coupler is used for filtering out a direct-current signal and a low-frequency signal in the alternating-current carrier control signal, and retaining a high-frequency signal in the alternating-current carrier control signal, so as to obtain a target carrier signal, wherein the target carrier signal and the first direct-current signal are modulated in a second power source line, so as to obtain a direct-current power source carrier signal; a second coupler is used for performing coupling on the direct-current power source carrier signal to obtain the target carrier signal, and transmitting the target carrier signal to a lighting module; and the lighting module draws power by means of the direct-current power source carrier signal and operates according to the target carrier signal. Four-wire transmission is not required, and thus the use of wires can be effectively reduced.
