DALI Version 2: Lighting Systems and Interoperability Benefit from New Standards and Mandatory Certification
The DALI trademark logo is internationally recognised as the mark that indicates the quality of interoperability of products designed to communicate according to IEC 62386. The original standard only covered control gear – devices that are usually directly connected to a lamp. To make a big step forward in system interoperability, the “DALI 2” standard was developed to include control devices for the first time. The first publications of this new version of the standard described the general requirements for such devices. Publication of four new Parts of the standard now enables standardisation of input devices such as push-buttons, occupancy sensors, sliders and light sensors. At the request of industry experts, a DALI 2 certification program was started in June 2017. The combination of the worldwide IEC 62386 family of standards and mandatory product certification greatly improves the quality of interoperability of DALI 2 products for use within lighting systems.
