IEA Annex 45 subtask BTask 53: Trends in lighting solutions
Use of efficient light sources, i.e. - fluorescent: T 5 with high output (instead of high efficiency) to
reduce number of luminaires- HID instead of tungsten halogen in spotlighting - Higher wattage in fluorescent (Compact > 120 W , T5 > 80 W)
LED global trend, growing efficacy, improoved colour rendering
Use of controls - daylight dependency- constant illuminance (to reduce initial illuminance to maintained)- Scene setting- Light changes accoring to a storyboard
IEA Annex 45 · Peter Dehoff Sep 5./6., 20064
IEA Annex 45 subtask B
Luminaires- Smaller- More emphasis on design- Better material to improove LOR- Better glare control using new techniques (mirco material)
Lighting interacts with other disciplines
