Demonstrator ETAP
How did we arrive at the concept definition and realization of our demonstrator?
• Information from the market about early failures of competition LED products in
hazardous environments like car parks.
• Results of corrosion tests (car park environment) on PCB’s executed by OUT, one
of the CYCLED partners, with as result :
Corrosion at solder pads close to the LED
(unsealed)

How did we arrive at the concept definition and realization of our demonstrator?
• Results of corrosion tests (car park environment) on PCB’s executed by OUT, one
of the CYCLED partners, with as result :
No corrosion at all when the LED is sealed.

Demonstrator ETAP
How did we arrive at the concept definition and realization of our demonstrator?
• So lessons learned : “Avoid contact between LED PCB’s and gasses.”
• Advise from OUT to :
• seal the individual PCB’s with a specific coating
• buy an application specific certified driver
• But …

Demonstrator ETAP
How did we arrive at the concept definition and realization of our demonstrator?
• For industrialization reasons decision made to make the luminaire itself gastight.
• Therefore the luminaire can be used in hazardous environments such as :
• general industry
• warehouse freezers
• chemical industry
• agricultural & food industry
• work stations
• sheds
• garages
• warehouses
• cellars

Demonstrator ETAP
What did we achieve on technical & ecological level in the product design?
• Reached a competitive Total Cost of Ownership (TCO) :
• Where the Energy efficiency < 1,3 W/m²/100 lux
• Used as little material as possible
• Used as much as possible recyclable materials (84%), like aluminium
• Integrated movement detectors, daylight sensors and emergency lighting
• Increased lifetime by
• Optimal thermal management
• Protecting LEDs from hazardous gasses / corrosion protection
