The US DOE has tested LED drivers in a stressed environment for as long as 7500 hours; and while there have been failures, the accelerated stress testing is said by the researchers to demonstrate improving driver reliability in the SSL sector.
From packaged LEDs to light engines to luminaires, better light quality was the clear trend at LightFair International, reports MAURY WRIGHT, and the march toward connected lighting and numerous specialty applications remains a strong backup story.
University Medical Center Utrecht is outfitting luminaires with network-connected chips and sensors that keep track of all the equipment that goes astray at hospitals. The same technology should provide a number of other benefits, MARK HALPER discovers
LUCA MENEGHETTI of Khatod and MAURY WRIGHT examine the ongoing advancements in secondary optics for LED-based luminaires, including material options and innovation in design that deliver optimal optical performance.
