The right concepts
Energy efficiency does not mean switching off the light
or reducing the illumination level, but:
Innovative light concepts:
Lamp:
- high efficiency (LM/Watt)
- colour property accommodated to products
Reflector:
- highest efficiency (light on the object)
- optimal reflector material (MIRO)
CAD design:
- product presentation
- reduce general illumination level, accentuate specific
areas with a unique reflector technique and lowest wattage
possible
- accentuation through optimal colour rendering instead of
creating „hot-spots“ and dark areas

Application
- Sales vehicles - Back walls - Signage
- Effect lighting - Pictures, pillars, etc. - food counter
Highlights
- no thermal load caused by IR- and UV radiation
(no “green” potatoes, low maturation of fruits)
- low thermal load in the surroundings
(lower climate control cost)
- no service costs for around eight years
- no limits to switch on/off function
- lower weight
Markus Ehrich
Additional Benefits for food cars:
-Reduced weight – less petrol consumption
- shock proof
