摘　　要：本文以单片机为控制器,采用色彩传感器获取工作面上的照度及混合光的色温信息来构建反馈环,设计了一种具有照度及色温自适应调节能力的LED台灯。经过实验验证,在不同的环境中,该台灯均能提供良好的工作面照明,在节约能源的同时,带来更加舒适的用户体验。In this paper, a self-adaptive LED desk lamp is designed. By utilizing the MCU as an intelligent controller and the color sensor to obtain illuminance on the work plane and the correlated color temperature value of mixed light, this LED desk lamp is capable for both illuminance and CCT control. Experimental results show that, in different environments, the lamp can provide satisfactory lighting condition with energy saved, leading to a more comfortable user experience.
