摘要
针对现有LED光源在舞台艺术表现力方面的不足,采用以ARM微处理器为控制核心,数据通讯协议为DMX512标准协议,利用PWM调光方法和拟合黑体轨迹的RGBW四色混光算法两个方面设计光源调光方法,研究实现了舞台LED灯具光色控制系统。实验结果表明,该控制系统满足对LED光源的大范围色温调节和色彩管理,增强了舞台LED灯具显色性能。
Because of the shortage of current LED stage light for art performance,this paper has proposed a new color adjustment method of LED light for the stage lighting control system with the control core of ARM microprocessor.The dimming data transmission of the system follows theDMX512 protocol.In addition,the PWM technique and four-color mixing model of RGBW are both used for the dimming method design.The experimental results have shown that this control system will achieve ideal color rendering performance and realize large range adjustment of color temperature,which is convenient for color management of LED stage lighting in modern theatre.
