Osram is an intra- interface for radio-based or sensor-controlled luminaires. The interface supplies both RF modules and sensors with power and also enables the exchange of data within the . The data is then transferred to a management via the RF module.

 

LED drivers with DEXAL® interface enable the easy and seamless connection of sensors and RF modules as well as the bidirectional exchange of data – opening up entirely new application options. Smart networks can be set up conveniently because the drivers feature an open interface which ensures compatibility with numerous management systems.

 

 

DEXAL® drivers with an RF module interconnect luminaires – with or without an integrated sensor – to form a close-meshed, radio-based network. The information obtained through intra-luminaire data exchange opens up numerous applications that bring essential benefits to luminaire manufacturers, planners and operators, and also to cities and communities.

 

DEXAL Benefits for lighting planners and operators

 

For Lighting planners and operator, the existing infrastructure is very important. They want to make the collected data available to other systems within the building. So lighting installation becomes the focal point for data transfer and exchange. But in the past, large and complex network of cables and wires had to be laid to set up a network of luminaires. Also, the system was quite inflexible, as for any subsequent change in the room layout lot of time and money had to be spent.

 

But now with availability of radio-based systems, this all has changed.  DEXAL® now allows the lighting planner to implement smart buildings – with the management system of their choice. Since luminaires now come with integrated sensors, this cuts down their planning workload considerably. And the lighting system can be conveniently reconfigured whenever required to use rooms in a different way – a major benefit especially for open-plan offices.

The DEXAL® drivers also provide lighting operators with a huge amount of luminaire data such as energy consumption, temperature values and operating hours.  Such data can be used efficiently to minimize energy consumption and help in preventive maintenance of lighting installation. Lighting operators can also monitor data of other sensors, which gets them important information on temperature, air humidity, and CO2 concentration levels etc. So once they have this information, an accurate analysis of usage patterns will help them to optimize the entire building systems.

 

DEXAL benefits for luminaire manufacturers

     

  • Manufacturers are able to build smart fixtures that support various systems.
  • Lower system costs
  • Significantly reduces the number of supported component configurations
  • Reduced installation space in the luminaire
  • Luminaire approvals and final production tests become easier
  • Integrated sensors enhances the value of luminaire
  • DEXAL offers a particularly low stand-by consumption
  • Using DEXAL drivers, they can produce both smart and non-smart luminaires because the data transfer can also be deactivated.

 

DEXAL – A future- proof solution

 

Another benefit for the users is that DEXAL is a future-proof solution, which means that it is not going to get redundant as it can be easily adapted to any changes in technologies such as to new wireless standards like 5G. Updates, upgrades or even complete changes are possible over the entire service life of 20 or 30 years.

 

Wide range of applications

 

The sensors connected to the DEXAL® interface can collect numerous types of data – including, for example, room occupancy and building utilization, the flow of road traffic, lighting levels, temperature, as well as air humidity and air quality. The management system stores and processes this data – also in the cloud as required.

 

The data can be used for many different purposes – from simple luminaire identification right up to higher-level IoT applications, integrating numerous individual systems into a comprehensive building management system. This also applies to systems used for street lighting and industrial lighting installations.
