基于颜色传感器的LED色温检测

Detection of LED Color Temperature Base On Color Sensor

目前节能环保的LED照明逐步流行,色温是LED灯的重要指标之一,在生产老化过程中对LED灯色温的实时监测是迫切需要的。而采用传统的光谱仪或照度计测量色温具有设备体积大、不能网络化的缺点。针对传统色温检测方法的缺点,提出一种基于颜色传感器的色温检测新方法,并结合CAN总线实现了多路色温在线监测系统,在监测LED色温的同时,对色温超出容限的LED给出标注并报警,给出了相关硬件电路和测试结果。

The energy saving and environmental protection of LED lighting gradually popular. LED is an electro luminescence.The spectrometer or luminance meter has the disadvantages of color temperature measurement. The disadvantage is the large equipment volume and not the network. In response to these shortcomings, we propose a new color temperature detection method based on color sensor. It realizes the online monitoring system for multi color temperature by CAN Bus. At the same time, if the LED color temperature exceeds the limit, the system gives alarm and annotation. The related hardware circuit and the test result are given.
