description The utility model relates to the field of color modulation circuits. The utility model discloses a color modulation circuit compatible with PWM and continuously changing voltage signals and a lightingdevice. The color modulation circuit comprises a first voltage division circuit, a second voltage division circuit, a first switch tube Q1, a second switch tube Q2, a unidirectional conduction circuit, a first LED lamp group and a second LED lamp group. The first voltage division circuit and the second voltage division circuit are respectively used for dividing the voltage of the power supply andoutputting the divided voltage to the control ends of the first switching tube Q1 and the second switching tube Q2; the control end of the first switch tube Q1 is grounded through the one-way conduction circuit and the second switch tube Q2 in sequence; the control end of the second switching tube Q2 is connected with a color modulation signal; wherein the toning signal is a PWM signal/continuouschange voltage signal; whe
