The utility model relates to a color lamp control device, which comprises an EM1 filter, a rectifier, an inverter, a lamp tube, a controller connected in parallel to the two ends of the lamp tube, and a variation controller electrically connected with the input terminal of the controller. The variation controller is composed of a power supply circuit, a single-chip, and an output port circuit. The input terminal of the single-chip is electrically connected with the power supply circuit; the output terminal of the singlechip is connected with the output port circuit; and the output port circuit is electrically connected with the signal input terminal of the controller. Working voltage on two ends of the lamp tube is adjusted by pulse width modulation technology without need of an electronic ballast frequent switch that is composed of an EMI filter, a rectifier and an inverter, namely, under non-interrupted working state of electronic ballast, the singlechip controls the output port circuit to drive PWM illuminance controller to control illuminance of the lamp tube, thereby realizing flashing effect. In cooperation with color lamp tubes of different colors, the control device can substitute the effect produced by conventional decoration lamps that are composed of neon lamps and LED lamps. Furthermore, compared with conventional decoration lamps, the utility model is more economic and practical.
