DALI总线在智能灯光控制中的应用

Application of DALI Bus in Large High-end Lighting

DALI是一种专门用于灯光控制的通信数字可寻址接口总线协议,它定义了电子镇流器与控制器之间的通信协议。在现代灯光控制中以其数字可寻址的优越性实现了主、控电路分离,即可在主供电回路改变时,控制回路不变,并可实现对某个或某组灯具进行单独控制。DALI总线在数据传输的可靠性能上明显优于现在常用的采用模拟信号传输的现场直接控制器。文章主要讨论DALI总线在大型高端场所灯光控制中应用。

DALI is a dedicated,addressable digital communication interface for lighting control bus protocol,which defines the communication protocol between the electronic ballast and the controller. In the modern lighting control with its digital addressable superiority to achieve the main and control circuit separation, the main power supply circuit can change, the control loop does not change, and can achieve a group of lamps or a group of individual control. DALI bus in the reliable performance of data transmission is superior to the commonly used analog signal transmission in the field of direct controller. This paper discusses the DALI bus in the large high-end lighting applications.
