A DALI lighting control system is an integrated composite of products that work in unison to enable digital networking of lights and controls. It features soft wiring terminations, rather than hard analog terminations, and implements control zoning and rezoning via software addressed to individual lights, groups of lights, or all lights within a DALI subnet. DALI is short for Digital Addressable Lighting Interface, a serial communication protocol based on Manchester Coding. The protocol was developed in Europe in a joint effort by a group of leading ballast and control equipment manufacturers, with the original intention to allow interchangeability of fluorescent ballasts and controls from different manufacturers. Soon after, it grew into a global standard and adopted by the International Electrotechnical Commission (IEC). In 2014, a new version of the DALI standard, also called “DALI-2”, was released with a strong focus on product interoperability. The DALI-2 standard also introduced more stringent test protocols and established requirements for application controllers and input devices. In 2017 the DALI Alliance, also known as the Digital Illumination Interface Alliance (DiiA), was established to operate the independently-verified DALI-2 certification program which aligns with the functionality specified in the version 2 of the IEC 62386 family of international standards. In 2019, DiiA announced D4i, an extension of DALI-2 intended to drive standardization for LED products targeting connected lighting and IoT applications.
