LED Innovation will Offer a Human-Centric Smart Lighting Platform Enabling Enterprise IOT
LED Innovation will Offer a Human-Centric Smart Lighting Platform Enabling Enterprise IOT After a century of analog electrical light, the lighting industry has spent the last decade in transition to digital light sources; LEDs, sought to replace the tungsten filament. LEDs are now embedded in all market segments in both residential and commercial applications. The predictions of early LED pioneers such as Dr. Roland Haitz have become reality today: more lumens delivered at a lower cost with increasing reliability and quality of light attributes. As a result, the world of electrical light has accepted that LEDs will be its primary light source and contribute to saving significant electrical energy, reducing carbon emissions and providing increased safety and comfort in our homes, at work and even while commuting in traffic.

Tech-Talks BREGENZ: Martina Paul, General Secretary, CIE (Article published in LpR #43)
Tech-Talks BREGENZ: Martina Paul, General Secretary, CIE (Article published in LpR #43) With the rise of LEDs as the future lighting technology, the relatively stable lighting industry faces many changes and challenges. One of the main challenges is the ever increasing speed of transitions, something already seen in the semiconductor business. Standardization organizations are facing similar challenges. On the one hand they should define standards that will last as long as possible and on the other hand the standards need to be as clear and precise as possible. Martina Paul, Secretary General of the most important standardization body, the International Commission on Illumination (CIE) was invited to the Tech-Talks BREGENZ to discuss these topics.

"Beyond LM Testing - A New Metric for Quality over Lifetime" by Thor Scordelis
"Beyond LM Testing - A New Metric for Quality over Lifetime" by Thor Scordelis In a recent blog post, the United States Department of Energy’s Jim Brodrick noted that solid-state lighting standards and testing methods “may not be glamorous, but they’re essential for the success of any technology, and SSL is no exception.” Certainly, this is true with respect to lumen quality, and for many years, the LM-80 standard, used to measure lumen maintenance of LED packages and modules, has sufficed. However, with the growing adoption of LED technology has come higher customer awareness and expectations. “Good enough” isn’t good enough anymore. Read more »
