The presentation will address the smart standards described in Zhaga Books 18 and 20 defining interfaces between indoor and outdoor luminaires and sensing/communication modules. These standards future-proof luminaires and ensure that they can keep pace with rapid developments in digital networking, sensing, smart-city, and building technology.

Modules incorporate the developments and are easily replaced. An installed base of luminaire with such interfaces drives innovation in the module market adding value to the lighting infrastructure. The existing certification and logo program creates further trust in the interoperability of luminaires and nodes from different vendors.

No prior knowledge required. This is an introductory course suitable for all experience levels from the student to the experienced design professional.

  • Understand the value and importance of specifying standardized lighting and control devices for indoor and outdoor luminaires.
  • Know the benefits and flexibility available through interoperable products that are supplied from multiple manufacturers.
  • Recognize how to future proof your digital lighting and control luminaire installations.
  • Learn how the lighting standards from Zhaga better enables connected lighting, buildings and cities while driving future digital innovation
