// Vision
• Lighting will be part of the Internet of Things‒ IoT development defines the technology roadmap
for connected lighting.
• OpenAIS defines an IoT based lighting system:‒ Defining a system architecture and use cases for future (2020
and beyond) connected lighting systems in buildings‒ Moving the lighting industry towards the vision for connected
lighting by converting it into an Internet of Lights
Note: with 200 – 400 million luminaires/year sold in 2020 the number of IoT lighting nodes will become a considerable part of the total number of IoT nodes (estimatied 35 – 75 billion)
// ARM Research Summit // 13-Sep-2017 // Henk Stevens // Cambridge // Public // Slide 5
// Mission
• Applying standard IPv6 connectivity to each node
• Exploit standards and HW & SW components from IoT applications & platforms:‒ Achieve economy of scale‒ Standards maintained by much larger industry
• Open architecture enabling multi-vendor interoperability
• Scalable and evolvable architecture allowing software application updates to extend control functionality after installation
• Serves as a valuable infrastructure for other functions in a building
// ARM Research Summit // 13-Sep-2017 // Henk Stevens // Cambridge // Public // Slide 6
// IP/IoT Convergence Benefits• IP based IoT will be mainstream technology with
advantages in (product) cost, development efficiency and availability of solutions and vendors.‒ Opportunities to decrease both CapEX and OpEx by leveraging
commodity HW, network and other software stacks
• Potential benefits for lighting industry:‒ Enable low cost introduction of new service
propositions by multiple parties. ‒ Opportunity for a single commissioning tool chain, lowering
complexity and development costs.‒ Combine multiple connectivity technologies, for example in both
wired and wireless solutions.‒ Eliminate the need for expensive gateways for doing application layer
translations‒ ,,,
// ARM Research Summit // 13-Sep-2017 // Henk Stevens // Cambridge // Public // Slide 7
// Scope
A reference Architecture for:• Control and communication
architecture for prof indoor lighting.• A multi-vendor and open IT
connected systems• Need for differentiation, openness
and future developments.
// ARM Research Summit // 13-Sep-2017 // Henk Stevens // Cambridge // Public // Slide 8
// Project approach and status
• Identify user and system requirements for the 2020’s‒ Easy Life: ...easy to specify, design, install, commission, operate and maintain‒ Increase building value: …make properties more attractive to lease or rent‒ Building wide ecosystem: …systems to share sensors and interoperate
• Define the best System Architecture for connected lighting:‒ To meet the requirements of the 2020’s‒ Exploiting the Internet of Things
• Realize a pilot installation in a real indoor setting
• Validate whether the pilot installation meets the requirements
• Prepare standardization by engaging with SDO’s
// ARM Research Summit // 13-Sep-2017 // Henk Stevens // Cambridge // Public // Slide 9
// System Architecture challenges• Existing IoT architectures do not fully meet the requirements
from lighting industry & stakeholders, gaps identified:‒ Secure Group communication (IPv6 multicast)‒ Object models for high quality lighting, data collection and integration into
BMS.
• Architecture solutions have been provided to resolve the gaps.• Reference Architecture has been published including object

// IoT extended for lighting (IoL)
OpenAIS:Adding the „local controls“ layer allows to adapt IoT technology to cover the user needs regarding group control and latency
IoT: Perfect services environment, but poor scalability, insufficient timing and massive online dependency for „switching lights“
// ARM Research Summit // 13-Sep-2017 // Henk Stevens // Cambridge // Public // Slide 11
// OpenAIS Group Communication (OGC)• Application group groups a set of related entities like:
‒ All luminaires controlled by a control object‒ A set of objects listening to one (or more) sensors
• Features of Group Communication:‒ OGC uses IPv6 Multicast to address many nodes at once‒ OGC applies sophisticated bandwidth optimization to avoid the
temporary overload of the RF band.‒ OGC applies group communication security that is fast enough for
lighting controls‒ OGC caters for complex device and controls structures.‒ OGC can be applied across diverse IoT frameworks, enabling
interoperability for lighting controls

• OGC (Group) communication with Security Identifications• Sensor Daylight and Sensor Dimmer in same group to share sensor status with basic control• Sensor On/Off status shared with Room Control to for further processing• Room Control to switch on/off the light based on its inputs from then sensor On/Off
// ARM Research Summit // 13-Sep-2017 // Henk Stevens // Cambridge // Public // Slide 13
// Complementary to IoT frameworks• Several IoT frameworks exist today (Allseen, OCF,
OneM2M, …) and some new ones will be created
• OGC is NOT replacing the IoT framework ‒ It is adding a supplemental layer, that is optimized for low latency lighting
controls needs.‒ OGC needs the IoT framework for all other communications, including
setup and commissioning.‒ OGC adds an „out-of-the-box“ set of features, that help the electrical
contractors to perform and verify their task. This is done to ease acceptance at the installers level
• OGC is open to be applied to future frameworks

• Advanced lighting control strategies: ‒ Granular sensing and control strategies (local dimming)‒ Local occupancy and light level sensing per luminaire‒ Personal control via Office App‒ Advanced use cases for emergency, light guide etc.
• BMS Integration‒ (Direct) control on lighting operational mode, scenes and schedules‒ (Direct) access to data collected by lighting system: occupancy & energy data
• BIM workflow management:‒ Verification of actual installation (as planned/as build):
• Reporting found, missing or misplaced device
‒ (Off-site) Simulation of system configuration, based on control behavior model.‒ Design of IP infrastructure (incl. lighting):
• Calculate nr.of IP (PoE) switches, Border Routers, power requirements, etc• Calculate IP cables length, define CAT5/6 cable labelling, etc.
