March 7, 2023

11:00am – 12:30pm EST

Room Location: Murray Hill

Credits: 1.5 LU / Elective

The emergence of digital lighting systems in North America drives a recognized need for interoperable components and calls for standardized interfaces. The Zhaga Consortium creates interface specifications for components of LED luminaires that enable interoperable products supporting smart cities and buildings. The DALI Alliance creates standards like D4i for controlling and powering intelligent, IoT-ready luminaires. Combining Zhaga and D4i gives the lighting world plug-and-play options. Digital communication within lighting systems brings improved performance and expanded capabilities, such as connection to external communication systems. This seminar explains how Zhaga-D4i products improve system performance and explores new capabilities supporting designers and specifiers.

Learning Objectives

  1. Recognize the value of specifying standardized digital lighting systems for plug-and-play interoperability.
  2. Understand the improved performance of D4i digital control versus analogue control in lighting systems.
  3. Realize the expanded capabilities of components in digital lighting systems.
  4. Learn how specifying Zhaga-D4i certified products future proofs your digital lighting and control installations and opens the market with multiple vendor product availability.
