Signify SR Partnership Zone

Lux Review
Signify SR Partnership Zone

THE ORGANISERS of the LuxLive 2019 exhibition and leading lighting manufacturer Signify have unveiled an ambitious new feature for this year’s event to drive adoption of the exciting Sensor Ready (SR) standard.

SignifyFor the first time Signify will exhibit alongside partners from its SR programme in a newly created Signify SR Partnership Zone.

Big names participating in the ‘show within a show’ include Enlighted, Gooee, Current by GE, Ubisys, CP Electronics, Itron, Nedap and Urban Controls.

The ambition of the Signify SR Partnertship Zone is to get the lighting industry connected to the brave new world of wireless control, data generation and the Internet of Things. 

SR is an industry standard which aims to ensure interoperability between LED drivers, sensors and gateways from different manufacturers.

Signify – formerly Philips Lighting – has been working on the standard alongside technology partners and industry bodies since 2013. It is now widely adopted by UK manufacturers.

'It's clear that as we move into the Internet of Things manufacturers cannot go it alone and we all rely on working with strong partners and robust open standards,’  said Signify commercial director for OEM in the UK and Ireland, Dervan Alleyne.

'What we're doing with the Signify SR Zone is giving lighting manufacturers a chance to understand how SR gives them an opportunity to work with really exciting technology and deliver more value to their customers.' 

The concept of the Philips’ SR drivers, is that, instead of having to individually wire power to the node, the SR driver powers the node over the Dali line, an element that’s been standardised and ratified in the industry by the Digital Illumination Interface Alliance, a global consortium of lighting companies.

Signify expects more SR installations to be wireless, but they don’t have to be.

The sensor is driven by the driver within the luminaire which eliminates the need for extra control wiring. There’s also an option to use a bridge for wired installations so that it works with all connected applications.

‘The main communication between the driver and what it’s powering - the node in this instance - is via Dali, as it’s the most used and the most recognised standard that people use’, says Alleyne.


From a node to a node, the communication could be Dali or Bluetooth or Zigbee but the communication between node and driver is always Dali 2.0.

The SR is a standard open protocol, so when other manufacturers bring out product, the communications to the node or sensor remains the same.

The benefits to the OEM manufacturer include a reduced cost of luminaire, because there’s no need for additional wiring to power the node.

Additionally, the open source nature of the standard means they’ll have a wider choice of suppliers.

‘If you’re using SR today, you’re future proofing for where the industry is heading, such a multiple sensing and the demand for data. It enables you to be ready for that wave when it comes though, and we’re already starting to see that’ says Alleyne. 

The outdoor sector is expected to be an early adopter of SR, with many of those first installations being about wireless control rather than gathering data from sensors.

While SR allows major cities to populate its street lights with sensors monitoring traffic volumes, air pollution and noise, the early applications of the tech will be as an easy way to create a wireless Dali system.

For instance, retrofitting the existing drivers in office lighting with a SR one means the building manager could have app-based control with no additional wiring. It also allows for grouping and scene setting in offices.

The most likely sensor connected to the ‘sensor ready’ driver is likely to be presence detectors, especially in office and high bay luminaires. Partnering companies have already brought SR-compatible product to the market.

‘It’s a new way of doing things,’ says Dervan. ‘Now the industry needs to act quickly if it is to take a major role in shaping the IoT. Otherwise it will get left out of the conversation’.

'We're extremely happy to take part in LuxLive 2019 and look forward to one of the most respected events in the lighting industry,' said Marcel Apfel, managing director of ubisys.

'Having been invited by Signify, the world leader in lighting, to jointly present the exciting achievements of the partnership between Signify and ubisys is a particular distinction. It validates the decision we made more than 10 years ago, to focus on and heavily invest in Zigbee in order to help drive and mature this international standard. 

'We believe that now the time has come to take advantage of what we experience as dynamic and sustainable market growth and are fully convinced that collaborations between technology leaders will help pave the way towards continued mutual business success.

'No doubt, this exhibition is the right platform to underline that our market-leading technology is the first choice for building interoperable, secure, scalable, reliable, robust, self-organizing low-power mesh networks for the lighting industry, whether it be in the residential or commercial space.'
