摘要
LED舞台灯具作为LED光源一种高端应用领域,具有长寿命和色彩快速独立调整等优点,应用越来越广.为了不断提高LED摇头舞台灯产品性能和可靠性,采用32位的嵌入式STM32F103芯片控制,代替原来的3片8位单片机,大大简化电路和程序,使软件性能大大提高.并对系统整体电路、运动控制方式、调光方式和温度保护等进行优化设计和实验,使灯具具有更好的整体性能、功能和可靠性,提高运动控制的准确性、稳定性以及获得近似无级四色光源的连续调光.已应用于多款LED舞台灯产品中,效果良好.
As an advanced application of LED light, LED stage light enjoys their unique superior per-formances of long life and fast independent color adjustment which are widely used in stage lighting.In order to continuously improve the product performance and reliability of LED stage lights, 32-bit embed-ded STM32F103 chip is used instead of the original 3-chip of 8-bit micro-controllers, greatly simplifying the circuit and procedure and significantly increasing the software performance.The researchers optimize and experiment the whole system′s circuit, the motion control way, the dimming way and the temperature protection to let the lamps have the better control performance, function and reliability, and to improve the motion control accuracy, stability and the approximately stepless four-color light dimmer.The princi-ple we develop has been applied to many head-moving lights which proves very effective.
