A Confusing Situation that demands Solutions: Performance Specification

Jacob Nuesink Product innovations are not the only consequence of recent advancements in the lighting market. These changes must be accompanied by a realization that the “old” methods for specifying the performance of lighting products no longer fully apply and need to be amended. From the perspective of DEKRA, an organization specialized in the testing and certification of SSL products, the current situation shows the following picture: Read more »

"Beyond LM Testing - A New Metric for Quality over Lifetime" by Thor Scordelis

Testing laboratory 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 »

LED Lighting Trends in 2012: The Rise of Lighting Solutions?

Pars Mukish works at Yole Développement as a Market and Technology Analyst in the fields of LED and Compound Semiconductors where he makes technical, economic and marketing analyses. He holds a Master’s degree in Engineering (ITECH – France) and a Master’s degree in Innovation and Technology Management (EM Lyon – France). He has worked as a Marketing Analyst and Techno-Economic Analyst for the past several years at the CEA (French Research Center). LEDs have already reached a sufficient “price/performance” level to enable massive adoption in LCD display applications. General Lighting applications will be the next and largest market for LED light sources. But the fact is that General Lighting can only take off if the cost/performance of LED based products can beat incumbent technologies. In that context, many of the lighting domain actors are developing new services in order to add innovation and value to Solid State Lighting, and differentiate them from traditional technologies. Will 2012 be the rise of Lighting Solutions? Read more »

Measuring the Oxygen Content of Blood with LEDs

Measuring the Oxygen Content of Blood with LEDs Pulse oximetry is a non-invasive method for determining haemoglobin (Hb) saturation through oxygen in the blood and heart frequency. It uses the fact that oxygen-rich and oxygen-poor haemoglobin absorb red and infrared light differently. In order to measure the oxygen content reliably, LEDs with ... Read more »
