一、摘要:
随着科学技术在不断的发展,人们分别设计出各种各样的开关来控制电路,如:拨动开关,按钮开关等。为了实现远距离无触摸控制电路,设计出红外遥控电路,该电路可用于走可用于家庭走廊、储藏室、卫生间照明或梳妆台镜前灯,只要人走近灯就亮,离开灯延时一段后又自动熄灭,使用十分方便。
本电路中主要由电源电路、红外发射电路、红外接收电路和调光电路组成。本文对电路原理图和实践作了简捷的描述,祥细介绍了CX20106、LS7232、7805等元件的功能,及其在不同领域所起的广泛的作用。

As science and technology in the constant development, there were a variety of switches designed to control the circuit, such as: Toggle switches, buttons, switches and so on. In order to achieve long-range non-touch control circuit, the design of infrared remote control circuit, the circuit can be used to follow the corridor can be used for home, storage room, bathroom lighting and vanity mirror front lamps, as long as people approached the lights on the bright lights left delay automatically extinguished after a period, is very convenient to use.
The circuit by the power circuit, infrared transmitter, infrared receiver circuit and the dimming circuit. In this paper, the practice of the circuit schematic and made a simple description of introduced CX20106, LS7232, 7805, such as ponen
