Outlook and summary


Decentralized intelligence

Lighting Control Network (LCN)

Wired (IP), Wireless (Zigbee)

‘Internet of Things’ design pattern:

• Nodes autonomously react to events raised by sensors in the network

• All decision processes take place locally at each node


Decentralized intelligence

Main advantages ‘Internet of Things’ 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 + embedded controller 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 the network can raise events using a new ZigBee profile

• Connection to Building Control Network via area controller

“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 analysis and

data mining


Modular Intra-Luminaire architecture

(Fully digital) Intra-Luminaire communication Bus interface (ILB):

• Allows to decouple lifecycles of independent technologies

• Enables market players to contribute, differentiate and compete

• Additional advantages in case of DC grids (Emerge Alliance)

Two step power

conversion

(SELV inside

luminaire)


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 expandability:

– 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.

optical properties

• High optical efficiency of lens (up to 95%), good color

mixing and uniform light pattern

Energy budget: Example wedge


Validation

Energy budget: Summary

(Excel)

• All luminaires fulfill EnLight energy saving target (40%)

• Definition of baseline sometimes critical due to missing comparator

• Spot is outstanding due to high LOR and low Tc

• No savings attributed directly to drivers, only indirect via intelligence

• For Wedge and Door energy saving may be somewhat lower due to the

“Rebound effect”

Lighting User Interfaces (UIs)


Intra-Luminaire Bus

How it works Three layer structure:

1. Application software, invoking a (local or

remote) function of the module (e.g. controller,

sensor) via standard message

2. SW bus, enabling the communication between

applications

3. HW bus (driver and physical HW) connecting

the SW buses running on separate processors

Technical Features:

• Reusable and exchangeable building blocks

• Portability to different physical communication

layers (e.g. I2C, RS485, …)

• Abstraction from implementation technology

(e.g. PIR, Ultrasound, )

• Application software integration into combined

hardware execution platform

• Multi-master mode enabling low standby power

• Plug and play

Intelligence by configuration

Rules: Structure


Sensor fusion is the combining of sensory data or data derived from sensory data

from disparate sources such that the resulting information is in some sense better

than would be possible if these sources were used individually. The term better in

this case can mean more accurate, more complete, or more dependable, or refer

to the result of an emerging view, such as stereoscopic vision (calculation of depth

information by combining two-dimensional images from two cameras at slightly

different viewpoints).

The data sources for a fusion process do not need to originate from identical

sensors.

• Central supply unit: – Galvanic isolation required only once

– PF, EMI, harmonics addressed once

– High power supply should be < 60V and switchable (to reduce

standby power)

• Split High and Low power supply: – High power for power demanding devices

(LLEs, some sensors).

• Voltage level impacts ohmic

losses, ECG architectures

• 24V Current choice

– 5V Low power for communication

The Rebound Effect

Source: vdi-nachrichten “Energy saving is partially balanced by change of user behavior. Examples: 1. If you don‘t switch light off, saying „I have energy efficient lighting“

-> Direct Rebound effect, can be addressed by EnLight via sensors. 2. If you spent saved money i.e. for a short shopping trip to New York

-> Indirect Rebound effect, out of scope of EnLight. -> Climate goals 20/20/20 are in danger. Examples broken down to EnLight demonstrators: • Hospitality: Hotel owner may spent saved money for investment in heated

swimming pool. • Office: Allianz shares may rise due to saved money and better EBIT.

-> Some shareholders may sell and proceed like described in 2)
