摘要
本文结合DALI协议的技术规范与LED便于调光的特点,设计了一套可调节光源色温的照明控制器。该控制器可同时分别控制红绿蓝与白光LED的输出功率,从而匹配出满足目标色温的光输出。同时通过反馈模块的实时监控和反馈调节,保证输出光的色温在光源长时间使用时也能保持不变。
In this paper,a color temperature tunable LED lighting controller is designed taking the advantage of both DALI protocol and LED technology. This controller can simultaneously and respectively control the red,green,blue and white LED outputs to match a certain spectrum to meet the targeted color temperature. Real-time monitoring and feedback regulation by the feedback module ensure that the color temperature of output light remains unchanged.
