摘要
为了使灯光系统达到视觉和听觉相协调的良好律动感,设计了无线智能的LED系统.首先对音频特征进行预提取,建立声音、音调与颜色HSV匹配模型,并根据无线控制的响应延时动态地调整指令发送时间,实现了音乐和灯光的同步变化.在某公司的智能照明系统的实际应用中,取得了良好的效果,初步实现产业化.
The LED lighting system with music effects is more and more popular. To achieve a good rhythm of vision with audition, this paper proposed an algorithm of music effects. The audio characteristics were firstly analyzed. Then a model was designed to match the HSV color to the volume and tone of the sound. And the time of control was dynamically adjusted according to the response delay dynamically. This design presented achieved the synchronized change of music and the light color. The method has been adopted in the intelligent lighting system in one company. It achieved a good performance, and realized the industrialization.
