New trends at Lightfair 2012: Fine motion control and incandescent-like dimming
At Lightfair 2012, Lighting Science Group introduced fine motion control for occupancy sensing while Juno Lighting Group and Osram Sylvania rolled-out incandescent-like dimming products.
Each Forefront LED product is designed as a one-for-one replacement of 100-750W HID fixtures, requiring 50% less energy usage. The flood luminaire features lumen output up to 23,000 lm, and can be used for façade, sign, landscaping or architectural lighting.
Also at Lightfair, LSG recently introduced its RoadMaster LED street light, which is designed to be a low-cost replacement for HPS fixtures. Approximately 4000 100-150W HPS fixtures are currently being replaced in Puerto Rico.
Lighting Science Group is also preparing to roll out a solar-powered street light that will be capable of 3-day autonomy. Named FreeLED, the luminaire will contain all power electronics in one unit and will use a next-generation lithium iron phosphate (LiFePO4) battery, which offers better thermal and chemical stability than other lithium-based batteries. According to Lighting Science Group, the LEDs used in this luminaire have an efficacy of 133 lm/W.
Osram Sylvania, Juno Lighting introduce incandescent-like dimming
Both Osram Sylvania and Juno Lighting introduced LED lamps capable of incandescent-like dimming at Lightfair 2012 to serve the needs of residential and hospitality environments.
Juno Lighting’s Chris Walsh, vice president of product management, explained that the company’s WarmDim recessed downlight (Fig. 2) received Lightfair’s Technical Innovation Award for the most forward-thinking advancement in LED lighting. WarmDim uses an on-board microprocessor to dim from 3000K to 2000K and is available on 4, 5 and 6-in downlights. The 600-lm downlight uses 14W of power. The downlights are available in retrofit or new installation versions.
