New Applications for DALI Lighting Controls

摘要

Digital Addressable Lighting Interface (DALI) is a wired communication system for control of lighting systems. DALI has been around since the 1990s and is now the most widely used dimming control system for interior lighting in Europe and many other parts of the world. DALI hasn't been a strong contender in the U.S. for interior lighting, but now it finds new growth in an outdoor lighting niche. DALI was created as a means to digitally control and dim ballasts in fluorescent lighting fixtures using a simple two-wire connection that can be wired as a daisy chain using inexpensive wire and, in many cases, can utilize the same conduits as the main electrical wiring. This makes wiring a DALI system easy and well suited for installation by electricians.
