Digital Addressable Lighting Interface (dali) Study

The crisis of electric system and shortage of energy produced by the fast development of economy, the popularization of high technologic production, etc. In order to resolve the problem, the people suppose many methods of saving energy and exploit new energy. "Green Lighting" and Intelligent Lighting Control System were means aim to the crisis of electric system. Digital Addressable Lighting Interface (DALI) is a digital communication protocol of Lighting Control System.The DALI protocol make up the disadvantage of traditional lighting control system, was established jointly by famous Co. of lighting equipment. They specially established one union:AG-DALI, in order to promote DALI protocol and popularize products based on DALI.This thesis described the background, the development the context of DALI and the advantage of DALI system. Analyzed and do some research of DALI based the comprehend of existing information. Designed a lighting control system based DALI.
