Tunable Dimmable White LED Using NXP^® Sensorless Sensing Technology (CES 2013 Demo)

When comparing LEDs to incandescent light bulbs, there is a noticeable difference in light quality: LED lamps when dimmed are perceived to be "colder" than incandescents. At CES 2013 this week, NXP^® is demonstrating a groundbreaking solution that allows LED lamps to closely mimic the traditional incandescent light bulb, to produce a warmer, cozier white light as they are dimmed. Featuring "sensorless sensing" technology, developed by NXP, this solution also has the advantage of driving down LED system costs by eliminating external temperature sensors, reducing the size of the heat sinks required for LED system cooling, and significantly improving reliability. http://www.nxp.com/news/press-releases/2013/01/a-warmer-cozier-white-light-nxp-transforms-led-color-quality.html
