摘要
数字化可寻址调光接口 (DALI)是一种专用于照明控制系统的通信接口规范。利用调光镇流控制ICIR2 1 5 9构成的镇流器控制电路 ,自动完成从灯预热、灯触发到灯功率控制的全过程。数字控制部分采用PIC1 6F6 2 8,它担任镇流控制器与DALI之间的接口。文中给出了调光曲线、编程思想。
Digital Addressable Lighting Interface(DALI)is a communication regulation suiting for lighting system management.The ballast based on IR2159,a dimming ballast control integrated circuit,can automatically complete preheating,ignition and dimming.PIC16F628 is used as an interface between the ballast controller and DALI.Dimming characteristics curve,programming idea,program flow and methods of minimizing power dissipation are given in the paper.
