In that post we noted that:<\/p>\n<ul>\n<li>LED Lights are moving into the 35W range giving them almost blinding brightness and the commensurate\u00a0is hot<\/li>\n<li>LED&#8217;s are driven by electronics and that means IC&#8217;s. The basic thermal building block here is junction temperature. And that has to be managed somehow for the electronics and therefor the light to have a reasonable service life.<\/li>\n<\/ul>\n<p><a href=\"http:\/\/www.avnet-abacus.eu\/\">Tim Haas of Avent Abacus<\/a>, has some additional thoughts on this topic from\u00c2\u00a0 his article in Electronics Weekly entitled, &#8220;<a href=\"http:\/\/www.electronicsweekly.com\/Articles\/2010\/05\/24\/48696\/led-lighting-systems-get-thermal-management.htm\">LED Lighting Systems Get Thermal Management<\/a>&#8220;. Among his important points he notes&#8221;<\/p>\n<ul>\n<li>The effectiveness of pre-formed heat sinks for LED is dependent on the maximum allowable junction temperature, the design of the heat sink and the ambient temperature.<\/li>\n<li>Techniques such as piped heat sinks are being augmented by the introduction of another new method which employs a &#8216;heat sheet&#8217;. Heat sheets are made from a graphite compound which is pliable and can be formed into various shapes, almost like a sheet of paper.<\/li>\n<\/ul>\n<p>Tim&#8217;s article is a quick read and worth our reader&#8217;s time as he does a nice job summing up the current LED Lighting thermal issues and highlights some of the current and new techniques necessary to solve them.<\/p>\n<p>ATS is holding a webinar on LED Lighting and Thermal Management on<br \/>\nThursday, September 23, 2010 2:00 PM &#8211; 3:00 PM EDT entitled, &#8220;<a href=\"https:\/\/www2.gotomeeting.com\/register\/235861098\">LED Thermal Management in Commercial and Consumer Lighting Applications<\/a>&#8221; All of our readers are encouraged to join!<\/p>\n<p><!-- AddThis Button BEGIN --><\/p>\n<div><a title=\"Bookmark and Share\" href=\"http:\/\/www.addthis.com\/bookmark.php?v=250&amp;username=xa-4c0e7a390bdcd09d\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" style=\"border: 0;\" src=\"http:\/\/s7.addthis.com\/static\/btn\/v2\/lg-share-en.gif\" alt=\"Bookmark and Share\" width=\"125\" height=\"16\" \/><\/a><\/div>\n<p><!-- AddThis Button END --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>While LED lighting brings the promise of more light and less energy use, they still create a proportional amount of heat.
