The invention discloses a device and method for controlling a circulating lamp. The device is formed by connecting a direct current voltage source, a bridge type unit, the circulating lamp and a single-chip microcomputer control circuit. The single-chip microcomputer control circuit is used for controlling the conduction time, the conduction period and the conduction sequence of MOS transistors in the bridge type unit. The method for controlling the circulating lamp is characterized in that the output terminal of the direct current voltage source is connected with the input terminal of the bridge type unit, the three-terminal output of the bridge type unit is connected with the circulating lamp, the six output terminals of the single-chip microcomputer control circuit are connected with the control terminals of the six MOS transistors of the bridge type unit to control the conduction time, the conduction period and the conduction sequence of the MOS transistors in the bridge type unit, and eventually the brightness, the period and the rotation direction of the circulating lamp are controlled. A circulating lamp device controlled by a bridge type circuit is simple in structure, the brightness, the period and the rotation direction of the circulating lamp can be adjusted, and therefore the good dynamic output effect can be achieved.
Description
technical field [0001] The present invention relates to a cycle light control device and method, in particular to a cycle light control device and control method controlled by a bridge unit. Background technique [0002] The cycle light control device controlled by the bridge unit is designed according to the working principle of the brushless DC motor. By controlling the PWM control signal sent by the single-chip microcomputer, the conduction period of the MOS tube group in the bridge unit and the conduction time of each MOS tube are controlled. and conduction sequence to adjust the cycle period, brightness and rotation direction of the cycle light. At present, most of the cycle lights are realized by digital circuits, and the control of cycle lights is realized through registers and cycle circuits. Therefore, the structure of the cycle lamp control device based on digital circuit design is relatively complicated, and the anti-interference ability is poor. Therefore, the ...
