Led Homemade Heatsink : 6 Steps - Instructables

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. NettetStep 2: Prepare the Heatsink Assembly. 2 More Images. 1.Put some Thermal paste on the heatsink and apply it with a metal strip evenly. 2. Repeat the process on all the surfaces, on both sides of the peltier and the metallic side of the LED module. 3.
