摘　　要：设计一种可对LED进行开关控制和亮度调节的无线遥控驱动电路。通过加减计数器、3-8译码器、数字电位器等模块用于亮度调控。反馈端联接光敏传感器或电阻进行电流控制,允许负载350 m A的大功率LED。此驱动电路具有自主选择性强,应用范围广等优点。Introduces a wireless remote control LED driver circuit. The wireless signal can be used to control the switch and brightness of LED. The driver circuit contains the up-down counter, 3-8 decoder and digital potentiometer which adjust the brightness. The driver circuit allows load 350mA high power LED, and the feedback can be connected with photosensitive sensor or resistance to control the circuit. The driver circuit has many advantages such as self-selectivity, wide application.
