The DALI Alliance (DiiA), the global industry organization for DALI lighting control, launched DALI+, a new brand that signifies DALI over wireless and IP-based networks.
DALI+ is built on the proven and sophisticated DALI lighting-control features in wired (DALI-2 and D4i) options and offers access to the same set of data from control gear, luminaires and sensors. DALI+ devices communicate using existing DALI commands, but these are carried over a wireless and/or IP-based medium rather than the dedicated pair of wires used by DALI-2 and D4i.
The DALI Alliance has published a new DiiA Specification, which supports DALI+ across different carriers and will lead to certification of interoperable DALI+ devices. The first certification program will be DALI+ with Thread, a low-power, IP-based, wireless-mesh networking protocol.
Paul Drosihn, General Manager, DALI Alliance, said: “Following the publication of our Wireless to DALI Gateway specifications last month, the introduction of DALI+ ushers in a new era of seamless, industry-standardized lighting control. DALI+ extends choice, flexibility and creative freedom for lighting designers and specifiers by supporting the development of wired, wireless and IP-based systems, using DALI throughout.”
DALI+ enables lighting solutions that can scale to building-wide networks, or even across multiple buildings, by using new addressing features. The implementation of IP-based networks in commercial buildings allows IT systems and building automation services, including lighting control, to operate on a common platform, with features such as end-to-end security, unlimited scalability, and easy connectivity to other applications.
Leveraging the existing features of the DALI protocol, DALI+ networks connect sensors, controllers and luminaires in a data-rich environment. It enables real-time monitoring of energy, power usage, and access to diagnostics information for predictive luminaire maintenance, among many other examples.
