摘要
LED照明系统逐渐应用到室内照明场所,具有智能控制,高效节能,环保等特点。大型舞台的专业音乐调光系统成本高功率大,不符合一般家庭用户,因此本文完成了一款高效LED调光驱动电源及其音乐灯光设计。上位机通过对MP音乐文件的解码,鼓点节奏提取,VB操作界面操作将信号用蓝牙串口通信发送给下位机,控制2x16路LED闪光的独立控制,实时反映音乐旋律的动态效果,为家庭照明提供了一款新型的低成本、稳定且操作简单的产品。
LED lighting system was gradually applied for indoor lighting,with intelligent control,high efficiency, energy saving, environmental protection and other characteristics.The professional music dimming system for large stages has high costs with low power, does not comply with the general household users.Hence,this paper achieves the design of an efficient LED dimming driving power and music lighting.The host computer through the decoding of MP3 files,the rhythm of drums extraction,VB interface operation will signal with the Bluetooth serial communication sent to the lower machine control,independent control of 2x16 LED flash,the dynamic effect of real-time reflect the music melody, provides a new type of low cost, simple operation and stable products for home lighting.
