light sensor. Juno Lighting won the Techni- cal Innovation award with their WarmDim LED Downlights that mimic the warming effect of incandescent lamps as they are dimmed. Meanwhile, over in the Department of En- ergy sponsored ‘Next Generation’ competi- tion, the real world of commercial luminaire development was recognised with Lithonia winning the best in class for general lighting with their LED volumetric lighting ST series. Lithonia showed an interesting integra- tion of solar collectors, from their recently acquired Sunoptics division and suspended ceiling luminaires. The same design of ceil- ing panel luminaire could utilise an LED, fluorescent or a solar light source supplied via a LightFlex collection tube. The solar design has more uses in sunny Nevada than in many other parts of the world but the development is an interesting approach to integrating daylight into buildings to achieve higher levels of energy conservation without sacrificing lighting levels. Lithonia also continued its pioneering work
in the development and marketing of OLED luminaires for commercial lighting under the guiding hand of Peter Ngai. Two new OLED products were introduced this year, Canvis and Trilia, marketed under the Wi- nona brand. The Canvis flexible OLED array was particularly noteworthy as it can create kinetic 3D surfaces of light panels with a novel hand gesture which controls both dim- ming and the electro mechanical adjustable suspension system. Lumenpulse was showing its Lumentalk sys- tem which is a bi-directional digital mains signalling system and allows luminaires to be dimmed and controlled over existing mains wiring. One of the novel features of the system was its ability to translate dim- ming levels from standard 1-10 Volt, DALI or DMX controls and send them over the system to be decoded at the luminaire end. Apparently the signals can be transmitted over multiple circuits in a building with a digital link module. Plasma lighting is continuing to gain mo- mentum for high lumen applications includ-
ing high bay, street lighting and, potentially, for architectural projectors. Three of the key players that exhibited at Lightfair included Ceravision from the UK and Luxim and Topanga from the USA. The Topanga arc tube design looked as though it would have a more usable configuration with the heat-sink than Luxim and could work with standard reflector profiles. The Hollywood fantasy version of technical lighting innovation as illustrated by Paul Debevec was a fascinating diversion from the more usual practical world of com- mercial lighting development. Maybe this was a pointer that more movie industry razzmatazz and creative thinking would benefit the rest of us in the wider, commer- cial lighting industry.
