tailieunhanh - LED thermal management

Historic gas street lamps in cities like Berlin, Prague and Warsaw can now be upgraded to energy-saving LED technology, thanks to a solid-state retrofit designed by Berlin-based Braun Schaltgeräte & Service with assistance from LED solutions provider Future Lighting Solutions. | LED professional ISSN 1993-890X The technology of tomorrow for general lighting applications. May June 2009 Issue 13 A Frontier in High-Power LED technology EHP-AX08 1W 3W 5W EHP-A07 lw 3w EHP-A21 lw EHP-B02 3w Ultra Bright - High Power LEDs EHP-B03 5w EHP-L02N 20w Evcrlight s portfolio of advanced High-Power LEDs deliver outstanding performance and exceptional power thanks to their low thermal resistance and high efficiency. Irrespective of your package requirements color choices or power demands we ve got what you re looking for all backed by over 26 years 0Í engineering and material expertise.

LED-FAIR International More Power -More Lumens Many companies in the lighting industry launched their new products at the Lightfair International in New York. It was a real demonstration of LED lighting in fact a LED-Fair. Now standard cool white LEDs are available with more than 130 lm W the first commercially available quantum dot-LED lamp was introduced a prototype of a 600lm dimmable LED bulb prototype for incandescent replacement was shown and a downlight prototype showed more than 100lm W fixture efficacy - only to name a few highlights. During the opening speech of the LIGHTFAIR International Mr. Provoost CEO of Philips Lighting called upon the industry to work together on the adoption of standards for energy efficiency along with open and collaborative innovation We call upon the lighting industry s stakeholders to seize the tremendous opportunity to embrace the changes being brought about by a combination of government legislation and economic stimulus to build a sustainable future. This is good news for the general lighting market based on high power LEDs and packages although Strategies Unlimited estimated that the High-Brightness-LED market will decrease by 5 in 2009.
