DALI Newsletter October 2020

Welcome to the October 2020 edition of the DALI Newsletter from the DALI Alliance (DiiA). Hopefully, you have already noticed our new branding, using the name “DALI Alliance” and accompanying logo. “Our organization has not changed," explains Paul Drosihn, General Manager of the DALI Alliance, "but the new DALI Alliance name clearly aligns with our core purpose.” More details can be found below. Meanwhile, we have launched the DALI Lighting Awards, and have also reached another milestone with the start of D4i certification of luminaire-mounted control devices. In related news, we have also added Part 208, covering switching control gear such as relays or solid-state switches, to the DALI-2 certification program.

D4i sensors and controllers for smart, IoT-ready luminaires

The DALI Alliance is now offering D4i certification of DALI-based control devices that are designed for mounting on LED luminaires. Eligible devices include light-level or occupancy sensors, as well as control nodes that can communicate wirelessly with external networks.

D4i is the DALI standard for intelligent, IoT-ready luminaires. By taking care of control and power requirements, D4i makes it much easier to mount sensors and communication devices on luminaires. In addition, intelligent D4i LED drivers inside the luminaire have the capability to store and report a wide range of luminaire, energy and diagnostics data in a standardized format.

DALI Alliance members are now able to certify their products according to the DALI Part 351 specification, which builds on the IEC 62386 international standard.

DALI Lighting Awards open for entries

The DALI Alliance has launched the inaugural DALI Lighting Awards, with a submission deadline of November 30, 2020. 

Held in association with arc (the international architectural lighting design magazine) and the International Association of Lighting Designers (IALD), the Awards will showcase and celebrate the best use of DALI control solutions in lighting projects across the world while also recognizing the importance of producing great quality illumination.

There is no entry fee, and all types of commercial, architectural and industrial lighting projects linked with DALI technology can be nominated. There are different categories for indoor and outdoor lighting.

Judges for this year’s awards include Matt Waring, the editor of arc;  lighting designer Tad Trylski, an active member of the IALD and former chair of its industry liaison group; and Scott Wade, Technical and Certification Manager for the DALI Alliance.

Zhaga-D4i luminaire certification to include ANSI C136.41 receptacles

Luminaires that contain both ANSI C136.41 receptacles and Zhaga sockets will be eligible in future for Zhaga-D4i certification, according to a new edition of the Zhaga Book 18 specification that is currently in preparation.

Hybrid architectures will be enabled by the upcoming Book 18 Ed. 3.0. A typical example is an outdoor luminaire with a Zhaga socket on the underside to accommodate a sensor, combined with an ANSI C136.41 receptacle on the top side for a network lighting controller.

The photo shows the relative size of the male connectors used by ANSI C136.41 (left) and Zhaga Book 18 (right).

Today, the larger ANSI C136.41 receptacle is offered by almost all luminaire manufacturers and is a requirement for many city and roadway lights, while the smaller Zhaga Book 18 socket is gaining momentum.

D4i questions answered

A recent Illuminating Engineering Society (IES) webinar provided a detailed update on D4i applications, technology and supporting specifications.

Entitled “See Your Lighting System in a New Light with D4i” the webinar was presented by Michael Davidson and Joe Hallman of DALI Alliance (DiiA) member Synapse Wireless.

Attendees asked a broad range of questions about D4i, and the presenters worked with the DALI Alliance to provide answers.

DALI Alliance unveils new name & logo

The Digital Illumination Interface Alliance (DiiA) will now use the brand name “DALI Alliance” to promote its ongoing activities that support market adoption of DALI lighting-control technologies, systems and products.

“Our organization has not changed, but the new DALI Alliance name clearly aligns with our core purpose,” said Paul Drosihn, General Manager of the DALI Alliance. “We are an open, global consortium of lighting companies, and we are focused on promoting the use of DALI as the predominant international standard for digital lighting control.”

To further build market recognition, the DALI Alliance will start to use a new logo based on the long-established and well-known DALI logo.

DiiA will continue to exist, providing the member-focused administrative structure that supports the public-facing activities of the DALI Alliance. DiiA is a Partner Program of IEEE-ISTO.

DALI Case Study: Old Admiralty Building

The installation of a DALI lighting-control system is a fundamental aspect of a major refurbishment project at the Old Admiralty Building in London.

Almost 7,000 DALI-addressable luminaires are controlled and monitored by the lighting-control system from CP Electronics. The company also supplied 1,800 PIR devices within the refurbishment to detect occupancy in different parts of the building and activate lighting accordingly.

“The main design challenges were due to the nature and scale of the installation,” explains Rob Crookes, Systems Project Manager at CP Electronics. “A DALI-based lighting control system was an obvious choice, especially as DALI is a long-established protocol which is very stable over large-scale installations.”
