<p>The present invention discloses a light-regulating circuit of an electromagnetic induction lamp, which is connected to a light-regulating electromagnetic induction lamp circuit at least comprising an active power factor corrector, a CPU, an electromagnetic inductor and a power follower. The light-regulating circuit comprises a closed-loop light-regulating control signal indicator connected with the active power factor corrector and the CPU, a lamp power feedback compensator connected with the CPU, a resistance-capacitance oscillating timer connected with the CPU, a lamp current sampling signal indicator connected with the electromagnetic inductor and the CPU, and a lamp voltage sampling signal indicator connected with the electromagnetic inductor and the CPU. It increases the function of monitoring to the operating condition of the strip lamp and carrying out real-time regulation, and further improves the operating efficiency of the electromagnetic induction lamp and prolongs its service life.</p> |
