摘要
采用单片机控制三路D\A转换输出,对LED红、绿、蓝三基色进行调节,实现对半导体照明色彩和亮度宽范围、高精度的调节,同时通过串并转换扫描方式使一套系统可对多个LED分别控制,实现其在高精度控光和控色的基础上可组成任意的静、动态图案或画面。
Three channels D/A, being controlled by single chip processor, adjust red, green and blue of LED, so that wide range and high precision adjusting of LED lighting is actualized. At the same time, the system can control numerous LEDs by means of serial and parallel conversion. Many static or dynamic pattern can be displayed based on light and color control.
