Intra-luminaire, bi-directional interface

OSRAM DEXAL is a non-proprietary, intra-luminaire interface which is based on the DALI standard. It provides power and enables bi-directional communications between the OSRAM OPTOTRONIC DEXAL LED driver and the fixture-integrated component.

OSRAM DEXAL technology allows manufactures to create smart, connected fixtures using one interface supported by multiple light management systems (LMS).

How DEXAL benefits agents

As part of a response to a specification which includes smart fixtures, an agent requests an OEM to build a fixture that works with a light management system.

  • DEXAL is a non-proprietary interface for bi-directional communication
  • Luminaires are set up for future smart building applications
  • DEXAL creates smart connected luminaires (smart nodes) compatible with various LMS systems

How DEXAL supports OEM

By utilizing an OSRAM OPTOTRONIC LED driver with DEXAL technology, manufacturers are able to build smart fixtures that support various light management systems.

  • DEXAL is a non-proprietary interface for bi-directional communication
  • Supported by multiple light management systems with “Works with OSRAM DEXAL" components
  • Analytics possibility using luminaire data
  • Significantly reduces the number of supported component configurations

How DEXAL benefits end users

DEXAL enables your fixture to become a smart node on a lighting control network

  • DEXAL extracts valuable, exact fixture-specific data for maintenance service, including:
    • Power and energy consumption
    • Temperature profile
    • Operating hours
    • Diagnostics and more

Thinking out of the box, turning design visions into reality

An interview with Nicolai Heber, product manager

OSRAM: Lighting plays an important role in architecture. Which challenges do we face today in the design of modern lighting solutions?

Nicolai Heber: Interior design concepts have indeed always been influenced by the lighting. However, due to the dimensions of electronic components, compromises had to be made in terms of luminaire shapes and sizes. LED technology has revolutionized everything and gives much more leeway for sophisticated luminaire designs.

Meet our DEXAL Partners

DEXAL is compatible with a growing list of industry-leading light management systems

The successful cooperation between OSRAM and its DEXAL partners ensures that their integrated luminaire components are fully compatible with our DEXAL-based OPTOTRONIC LED drivers when operated together in one system. The DEXAL technology thus enables luminaire manufacturers to integrate a large number of different sensors and light management components, whereas lighting planners greatly appreciate the wider spectrum of choices from which they can select the best matching LMS system and luminaire for their specific project. OSRAM cooperates with its partners to jointly develop the smart luminaires of the future. Parallel to this, OSRAM supports activities for the standardization of this concept in the global lighting industry.
