摘要

针对两通道冷暖LED光源PWM调光调色照明灯具的巨大市场需求以及当前该类技术存在的问题，提出一种基于时间混色方式的照明光源系统控制算法，实现混色光源色温与亮度的独立调制.实验结果表明，在色温调节过程中，光源亮度基本保持恒定；在亮度调节过程中，光源的色温也基本保持恒定.该算法在降低控制器运算量的同时，提高了调光调色的控制精度，消除电源瞬态过载现象，提高了照明系统可靠性.

Abstract

According to the huge market demand for the PWM dimming lamps of two-channel cold/warm LED lighting source and the existing problems in dimming technique

a lighting source system control algorithm based on time hybrid color mode is proposed in this paper and the independent modulation of hybrid lighting source luminance and color temperature are realized by this method. Experimental result shows that

in the process of color temperature adjustment

luminance keeps constant basically. And in the process of brightness adjustment

color temperature is also constant. This algorithm reduces the computing load of controller. At the same time

it improves the dimming control precision and eliminates the transient power overload phenomena for reliability of lighting system.
