LED Breakthrough Promises Ultra Efficient Luminaires

Korean firm LG unveiled the first commercially available, stable LED to break the 220 lumens per Watt barrier. The development is significant because the LEDs can survive the 300 degree soldering process without a degradation in performance. It makes possible the widespread availability of light fittings with efficiencies of over 200 lm/W. Currently the best commonly-available light fittings are around 150 lm/W. LG’s development is a so-called ‘flip chip’ LED. Flip chip LEDs are brighter and cooler than conventional LEDs and are wirelessly bonded. Compared to surface mount technology, flip chips last longer, have better quality light and dissipate heat better. http://luxreview.com/
