MAIN ACHIEVEMENTS FROM SY-PROGRAM
¢ 
LED driver optimization
•  Efficiency, Size, Stand-by power, Cost, TTM
=> Modular building blocks for next generation LED drivers
¢ 
Vuores school living pilot
•  Integration of Helvar lighting system with Schneider Electric building
automation system
=> Energy saving, cost saving in maintenance, reporting…..
¢ 
Lighting workshop for RYM partners
•  Presentations and group works
=> Increased automation in lighting , less complexity, end user interaction
¢ 
Lighting Hackathon weekend
•  Helvar, Fidelix, Ledil, Aalto, Elli-cooperation
•  Participants designed applications using Helvar lighting systems, Fidelix control
systems and Ledil optics.
⇒  Phone control, GPS positioning, PC camera control, gesture control, new type
luminaire
¢ 
Self learning lighting Concept – Helvar Active
NEW OPPORTUNITY TO SAVE ENERGY
¢ 
Lighting control is the key to Energy saving
STILL
¢ 
Majority of NEW luminaires installed are NON CONTROLLABLE
(Stand alone)
Intelligent luminaire concept
based on local sensors
ACCESS TO SENSOR INFORMATION
¢ 
¢ 
The number of various type of sensors is increasing
dramatically in lighting.
It has never been easier to collect sensor information
¢  What
to do with that
information ?
HOW TO SAVE ENERGY WITH STAND ALONE
LUMINAIRES ?
... with simple sensors (PIR&CL)
&
... intelligent LED driver
OR
… intelligent ballast
§  Self learning features –> no commissioning
§  Increased intelligence is based on sensor information and driver SW
algorithms and rules –> 40 % increased energy saving
WHAT IS THE CONCEPT?
ACTIVE LIGHTING – SELF LEARNING
¢ 
¢ 
¢ 
Learning period: 60-100 hours
A single luminaire or in a group of other luminaires =>
different PIR on times (10 min or 85 min)
What is the location - close to external lights or not => different
dimming ranges (25-100% or 80-100%)
Am I
alone…?
I’m over
here.
Are there
external
lights ?
WHAT IS THE CONCEPT?
ACTIVE LIGHTING – IN OPERATION
¢ 
Automatic energy saving
•  Constant light functionality
• 
• 
Active when influenced by external light (for ex close to windows, aisles)
Minimum level clamps to a higher level when no external light is present
•  PIR absence detection
• 
• 
Quick switch OFF for single luminaires
Long transition period on minimum level when other luminaires in the surrounding
•  Maintains designed light level over entire life cycle
• 
• 
Avoiding over-illumination of new luminaires
Light level set between 85-100%
LET’S BE ACTIVE
