As shown in FIG. 2, the data signal is composed of the pixel data signal and the synchronous display signal. The composition, wherein the signals T1, Τ2, Τ3, Τη-1, Τη are pixel data signals corresponding to the lamps L1, L2, L3, Ln-1, Ln in Fig. 1, respectively, and the signal Tt is a synchronous display signal.
各个灯具的驱动电路根据其与控制器 11之间的协议， 选择接收与其对应的像素 数据后， 由信号发生单元最后发出一同步显示信号 Tt至系统各个灯具的驱动电路 ， 驱动电路同吋控制相应的显示灯 （如 LED) 点亮。 其中一个完整的数据信号帧 周期包括像素数据周期和同步显示信号周期。 The driving circuit of each luminaire selects and receives the pixel data corresponding thereto according to the protocol between the luminaire and the controller 11, and finally sends a synchronous display signal Tt to the driving circuit of each luminaire of the system by the signal generating unit, and the driving circuit is controlled by the same The indicator light (such as LED) lights up.
