1、摘要在生活当中，照明在能耗当中所占的比例越来越大，当今照明的节能越显重要。一个好的照明控制系统，能为人们的生活、学习、工作等提供良好的视觉条件，营造舒适的光环境。目前在国内和国外通常使用的大概有这几种类型：触摸型、声控型、感光型等。论文主要介绍了基于单片机的家庭智能LED照明灯具的设计。设计采用单片机作为控制系统，结合LED照明技术、光感技术、红外传感技术等实现了对照明设备的智能化控制。智能化照明设备克服了传统照明设备耗能、不便于调节光强等缺点，实现了对光强调整的人性化、智能化的控制。硬件设计主要包括单片机控制电路、按键电路、LCD显示电路、热释电传感器处理电路。软件设计主要包括单片机

2、主控程序、ADC控制程序的设计和LCD显示程序的设计。家庭智能LED照明灯具通过人体感应模块（热释电传感器）决定LED灯的关闭和开启。同时可以通过光照检测电路对周围环境亮度进行检测，进而实现对LED灯的控制。设计通过点亮LED灯的个数来实现光照强度的调整，同时可用按键熄灭或者开启一组LED灯。解决了照明设备关闭、自适应调整和自动开启的问题，从而达到良好的光环境和调光效果。关键词：单片机；光敏传感器；节能；LED灯；智能控制ABSTRACTInlife,lightingintheproportionofenergyconsumptionwhichismoreandmorebig,thee
