DALI Ecosystem Continues to Evolve

The DALI Alliance's focus for Light+Building 2026 includes a new certification program for wireless-to-DALI gateways, ensuring standardized translation between DALI systems and wireless protocols like Bluetooth Mesh and Zigbee. This development aims to broaden the range of interoperable solutions for developers and building automation professionals. The event will also feature the DALI Lighting Awards, recognizing outstanding projects using DALI technology. Further expanding the ecosystem, DALI+ brings the DALI protocol to wireless and IP-based networks. The initial focus is on DALI+ with Thread, which will allow DALI devices to integrate into a self-healing mesh network, sharing the IP network with other protocols like Matter and KNX. This enables seamless connection with broader building automation systems and allows for real-time data monitoring and analytics. The integration of DALI with IoT systems is advancing human-centric lighting. By using sensors for occupancy and daylight levels, DALI systems can automatically adjust lighting to create more comfortable and energy-efficient environments. This precise digital control is crucial for tunable white lighting, which mimics natural daylight patterns to support circadian rhythms, enhancing alertness during the day and promoting better sleep at night. For designers, these advancements align with standards like the WELL Building Standard, which uses metrics like Equivalent Melanopic Lux (EML) to measure the biological impact of light on circadian rhythms. Achieving specific EML levels, often through tunable DALI systems, can contribute to WELL certification and support occupant health and well-being. The goal is to provide biologically effective illuminance, such as the 250 MEDI Lux recommended by DIN SPEC 67600, to properly regulate the body's internal clock. The industry is also seeing a strong push towards sustainability and a circular economy. This involves designing luminaires for longevity, repairability, and disassembly, using modular components made from recycled and recyclable materials. Assessing the full "cradle to cradle" environmental impact is becoming a fundamental aspect of lighting product specification. From a leadership perspective, the increasing complexity of lighting systems requires a deeper knowledge of both design and technology. Design leaders are expected to guide their teams in integrating these advanced systems while also influencing product roadmaps to align with trends in building automation and sustainability. This expertise is critical for creating products that resonate with architects and specifiers who frequent publications like *Dezeen* and *Architectural Record*. The WAGO CC100 DALI interface, a compact controller with an integrated DALI Multi-Master Module, exemplifies the hardware evolution supporting these trends. Certified to the DALI-2 standard, it allows for direct connection and management of DALI lights without an additional gateway, simplifying the automation of smaller, integrated lighting solutions. Its real-time Linux® operating system offers programming flexibility with tools like CODESYS, Python, or Node-RED.
