该文在简单叙述DALI规范的基础上,给出了基于DALI标准的照明控制系统的实现,详细讨论了系统主控器端和镇流器端DALI电平和CMOS电平之间的转换电路的设计,简单叙述了DALI主控器和DALI镇流器的功能结构。实验结果表明该文设计的DALI通信系统的各项性能符合DALI规范。该文讨论的DALI照明控制系统在满足高性能的照明需求的同时,对降低照明系统的能源消耗也起到了显著的作用。该文给出的DALI通信系统同样适用于HID以及LED等新型电光源。

In this paper, the DALI specification is presented simply, and then the realization of lighting control system based on DALI standard is discussed. The design of electrical level transfer circuit between CMOS electrical level and DALI electrical level is discussed in detail, and the conformation of DALI controller and DALI ballast is also pointed out briefly. The experiment result indicates that the DALI communication systems designed in this paper conform to DALI specification. They can meet the advanced lighting demand, contribute to saving the power consumption of lighting system at the same time and are also suitable for other electrical light sources such as HID and LED.
