The Zhaga Consortium has published a whitepaper, “How Zhaga addresses Sustainability and the Circular Economy.” The publication points out that durable, repairable, and upgradeable LED luminaires are key elements to sustainable lighting. It explains that Zhaga is developing and standardizing interface specifications for components of serviceable luminaires, to help facilitate a new market framework called “Circularity Lighting.”

Sustainable action in the lighting industry entails the provision and continuous development of energy-efficient lighting solutions and the resource-saving design of durable and serviceable products. Serviceable products and systems are characterized by properties like repairability, upgradeability, replaceability, being future proof and durable. Such products and systems are designed in a modular way and the interfaces of the components used are based on standardized and widely recognized specifications. Zhaga uses the term “Circularity Lighting” for a market framework with products and systems that support the aims of the circular economy through enhanced serviceability.

The whitepaper describes various problems to be addressed:

  • The different life cycles of luminaires and connectivity solutions.
  • Even luminaires of high quality and durable design can experience an early failure.
  • An upgrade of product features may be desired.

Solutions are illustrated referencing to the Zhaga specifications:

  • Book 18 and Book 20 about intelligent interfaces between outdoor resp. indoor luminaires and sensor /communication modules.
  • Book 24 and Book 25 that allow programming of LED control gear from different manufactures by using unified NFC programmers.
  • Book 21 and Book 26 about linear socketable LED modules that allow the selection of modules with desired characteristics (efficiency, color temperature, CRI, etc.).
