设计逆变式LED彩灯控制系统的目的，主要是解决目前市场上的彩灯只有220V供电，且彩灯的色彩单一，移动性能差的状况。本系统采用3V干电池进行供电，具有良好的便携性能。此外，我们将LED彩灯分成红、绿、蓝三种颜色的，通过这RGB颜色的变化以及PWM脉宽的调节，可以调制出各种各样不同的颜色。为了实现彩灯的串联，我们还将3V电压升至34V。彩灯的颜色以及式样的控制则由单片机进行控制。-LED lantern design inverter control system seeks to solve the lantern on the market only 220V power supply, and a single color lanterns, mobile performance situation worse. The system uses a 3V batteries for power supply, portable with good performance. In addition, we will LED lantern is divided into red, green, blue three colors, and the passage of the RGB color change and the regulation of PWM pulse width can be modulated from a wide variety of different colors. In order to achieve Lantern series, we will rise to 3V voltage 34V. Carnival of Color and style of control by the single-chip control.
