The invention discloses a rotating lamplight device. The rotating lamplight device is characterized by comprising a support body, wherein a servo magnetic ring is arranged in the middle of the support body in a surrounding manner, the support body is further provided with a plurality of spotlights, the support body is further provided with a control chip, the output end of the control chip is connected with the input ends of the spotlights and the input end of the servo magnetic ring. According to the rotating lamplight device, the two ends of the support body are hinged to a wall of a bar or a support erected temporarily for a concert through hinged pieces, the control chip transmits control signals to the servo magnetic ring, rotation of the support body is then achieved, and the spotlights are driven to rotate to generate rotating lamplight. Meanwhile, the control chip sends out control signals to the spotlights to control the spotlights to be turned on or off, and an intermittent type lamplight environment can be generated. Besides, the detachable hinged pieces can achieve rapid assembly and disassembly of the rotating lamplight device, and the rotating lamplight device is convenient to carry and transport and good in stereoscopic lamplight effect.
