About this session:
Lighting control systems have traditionally been considered too complicated and expensive to provide in all but the largest or most sophisticated classrooms or event spaces. With the advent of DALI (Digital Addressable Lighting Interface), an international standard for lighting control, there is now a solution that can be deployed broadly at a reasonable cost. DALI has received wide-‐spread acceptance in Europe but it hasn’t been until recently, that it has made inroads into the US market.
This presentation will cover the basics of DALI lighting and provide a case study of how DALI lighting has been used at the University of Maryland in rooms ranging from small seminar rooms to large lecture halls with over 500 seats.
DALI systems control each ballast or light individually which means that a nearly infinite number of lighting scenes can be programmed to meet the needs of different classes and learning formats. More importantly, if the use of the room changes over time, you don’t need to rewire lights to accommodate the new users. Or if a room needs to accommodate a variety of learning activities or groupings, which is the case in many collaborative or informal learning spaces, you simply program the lights with the different scenes needed for each.
When UM first started using DALI, the types of lamps and fixtures were rather limited-‐-‐primarily 2x2 and 2x4 fluorescents. That’s not the case today. DALI can be used to control all types of lighting (incandescent, fluorescent, and LED) and the variety of fixtures is extensive.
Many of the traditional lighting control systems used in larger venues are very complicated and require a lot of expensive components. DALI systems are much simpler and can scale to accommodate even very large rooms. This presentation will cover the basic components of a DALI system, how they are controlled, how they are integrated with AV control systems and building management systems, as well as typical costs when compared to more traditional systems.
