LED Heat Sink: What Is It and Why It’s Important?

Nettet1. mai 2008 · Because most market applications for LEDs shy away from liquid cooling, the focus of this article is on air cooling of LEDs. Most LED lamps use familiar heat-sinking techniques. In some cases, the metal fixture of a luminaire can act as a heat sink, but the thermal requirements of its LEDs must be considered when designing the unit. Nettet16. mai 2011 · LEDs dissipate heat almost solely through conduction, therefore it gets hotter at the fixture. LEDs are not much different from SCRs, transistors, CPUs,etc. They do not like heat and depend almost entirely on conduction by heat sink for cooling since they can't run at high enough temperatures to reject heat by infrared. bish up to me 歌詞

"NettetIt might be better to order a tranformer for a DC led cob. Most DC 50w led cobs run on 30-36volts and 700mA to 1A. Which is a lot safer to handle. You can even use like a 12V transformer and a dc-dc boost convertor circuit to bring it up to 36volts. I didn't mean to frighten you, but would hate to see someone hurt themselves with mains voltage.

NettetConstant on LEDs will create more heat than pulsed. If you have a large thermal mass, it acts to draw the heat away from the chips, just like a finned heat sink does. Air flow alone can change the design. Many A19s don't have heatsinks anymore because they have a way to allow air flow around the LED to cool it down. Same for higher efficient chips.
