The DALI Alliance recently unveiled much-anticipated certification details for its wireless specification: DALI+ over Thread.
As lighting specifications increasingly seek smarter, sustainable, and interoperable solutions, DALI+ seeks to position itself as a crucial enabler of standardized wireless or IP-based lighting systems. The alliance’s collaboration with partners such as Thread Group has resulted in the integration of enhanced security and encryption solutions, ensuring the integrity and confidentiality of data transmission within DALI+ networks.
Key features of DALI+ with Thread include:
• Wireless Mesh Network: Thread creates an Internet Protocol version 6 (IPv6) based wireless mesh network. Off-the-shelf Thread border routers can also be used to connect multiple Thread networks through IP technologies such as Ethernet or Wi-Fi, allowing a highly scalable lighting control system.
• Extended Addressing: In addition to the standard 64 control gear and 64 control device addresses, DALI+ with Thread IPv6 routing allows almost unlimited addressing capability. The usual DALI broadcast, group and short-addressing methods are included together with IP unicast and multicast capability.
• Interoperability: DALI+ certification includes all the benefits of the existing DALI-2 and D4i certification programs with extensive testing, independent verification, and listing of every certified product in a publicly searchable product database to ensure a high level of product interoperability. Furthermore, DALI+ bridge devices will allow DALI-2 wired devices or systems to connect with and operate with the products in a DALI+ wireless system.
• Device Support: DALI+ supports a wide array of control devices, including occupancy sensors, light sensors, switches, sliders, rotaries, and pushbuttons. Control gear support currently includes LED drivers with the three optional data parts: luminaire data, power and energy, and diagnostics data.
