Standards harmonization drives interoperability for lighting control

Certification programs based on international standards build confidence in the interoperability of lighting-control devices, and the benefits are magnified when related standardization efforts are harmonized.

This article by Paul Drosihn, General Manager of the DALI Alliance, discusses DALI standardization and the certification programs developed by the DALI Alliance, including DALI-2 and D4i, and then describes the harmonization between D4i and the new ANSI C137.4-2021 standard.

DALI-2 raises the bar for emergency lighting

The article explains how the DALI Alliance has extended its DALI-2 certification program to include control gear for self-contained emergency lighting (where the battery is inside, or next to, the luminaire). DALI-2 certification enables manufacturers to ensure their products will be interoperable with those from other suppliers. This means that lighting designers and specifiers are not locked into one vendor, and can choose the best certified product from any provider.

Lighting controls benefit from standards and certification

With global standards, lighting projects can be future-proofed, with no vendor lock-in, and customers benefit from long-term confidence in the supply chain.

Wireless lighting control standardised by DALI+

Wireless lighting control is an area that would benefit from further standardisation. Until recently, there has been lack of industry-standard protocols dedicated to wireless lighting control. This article explains the new DALI+ specification, which enables existing DALI commands to be carried over wireless and IP-based networks instead of the dedicated pair of wires that are typically used to connect DALI devices.

DALI-2: Standardized, interoperable components and smart luminaires

By Scott Wade and Tim Whitaker, DiiA - Presented at LED Professional Symposium 2018

DALI-2 extends and enhances the strengths of DALI as a dedicated, standardized protocol for digital lighting control. For many years, the lighting community has installed DALI systems that are robust, scalable, cost-effective, reliable and flexible. But now, for the first time, DALI-2 has brought standardization to products such as sensors and other input devices, as well as application controllers, which are the “brains” of a DALI system. Furthermore, with its rigorous testing and verification procedures, the DALI-2 certification program from DiiA brings the promise of significantly-improved interoperability of products from different vendors.
