摘　　要：随着LED照明技术的迅速发展,对LED自适应调光技术的需求越来越强烈。该文以AVR单片机中Atmega16作为控制器,利用基于CI2(Inter Intergrate Circuit)总线的数字型光强度传感器集成电路BH1750FVI采集室内环境光照度,完成LED自适应调光系统的硬件设计和软件编程,最终维持温室箱内植物光照强度在一个设定水平。As the fast development of LED lighting technology,LED adaptive dimming technique is needed more strongly.It was presented that the Atmega16 in AVR single chip computer was used as controller,and the digital light intensity sensor integrated circuit BH1750FVI with I 2C （Inter Intergrate Circuit）bus was employed to measure the indoor ambient illuminance.The hardware designing and software programming of LED adaptive dimming system was completed in the paper,eventually maintenance greenhouse box plant light intensity in a setting level.
