Trends in Lighting
 “Lighting going digital”
– Move towards a SSL Semiconductor-like value chain
 “Liberation of Light”
– New form factors, novel applications,
user centered and omnipresent
 “More illumination”
– Drive for efficiency up (Lumen/W) and cost down
(Haitz’s law)
 “More than illumination”
– Add more functionality to increase value
 “Going Green”
– Energy efficiency & sustainability as societal themes
 Daylight Harvesting
– Using as much daylight as possible

Decentralized intelligence
Wired (IP), Wireless (Zigbee)
‘Internet of Things’ design pattern:
• Nodes autonomously react to events instead of being instructed by a
central controller
• All decision processes take place locally at each node
• Behavior determined by rules configured during the commissioning phase

Decentralized intelligence architecture
‘Internet of Things’ Architectural design pattern:
•
•
No central node & no global knowledge of network topology is required
All decision processes take place locally at each node and no global
knowledge of the network is required a priori
Intelligent Luminaire is cornerstone building block:
•
•
•
Autonomously controls brightness, CCT, color, beam shape, …
Reacts to events instead of being instructed by e.g. a central controller
All nodes in network can raise events
“Intelligence by Configuration”:
•
•
•
Rules based behavior, configured during commissioning phase.
Flexible: ability to adapt/change behavior per node.
Self learning: ability to adapt behavior as result of global data mining.
Smart Lighting 2013 conference | Frankfurt | Frank van Tuijl | Consortium Public | 14 May 2013 | Slide 14
Rule based intelligence example
• Set of rules determines the behavior of each luminaire.
• Rule = event, condition, action
Luminaires
Presence sensors
Desired behavior:
– Each luminaire is switch off in case of absence
– Luminaire is on (100%) in case of presence
– Luminaires are 70% dimmed if a neighboring luminaire is on.

Why decentralized architecture
•
Robustness:
– No single point of failure but graceful degradation when node fails
•
Scalability:
– Investments, complexity and intelligence grow linear with number of nodes
– Low entry level
– Combines smoothly with today’s systems (i.e. non-intelligent luminaires)
•
Modularity and extensibility:
– Nodes can be easily added, changed and (re-)configured
– Enables luminaire differentiation in functionality and performance
– Feature up during luminaire lifetime.
•
Effectiveness and reduced complexity:
– Less complex commissioning when using local embedded sensors
– Built-in presence detectors increase overall energy efficiency
compared to centrally placed external sensors.

Modular intra-luminaire architecture

Intra-Luminaire communication Bus interface (ILB)

Summary
•
Enlight capitalizes upon the intrinsic benefits of LED technology and the
trend toward LEDification and digitalization.
•
Enlight explores a next generation lighting system with:
– Decentralised, rule based, intelligence in the luminaire and end nodes
– Modular intra-luminaire architecture with a ILB digital bus interface
•
Enlight’s modular intelligent luminaire approach fuels:
– managing the increasing diversity and complexity of luminaires
– integrating innovative functionality enabled by the integration of silicon
and local intelligence
– improving both energy efficiency and lighting comfort
•
The consortium partners are developing ILB building blocks, intelligent
