Led Homemade Heatsink : 6 Steps

Small leds of 1watt are now commonly available which require a small heat sink. cheapo led when bought with attached heat sink almost costs double, so I decided to built some homemade heat sink with worn away parts.

list of parts required=

1.Hammer

2.Big sand paper

3.Iron cutting hand blade

4.Aluminium panels like in glass sliding

5.Useless choke of a tube light from scrap

6.glue

7.screwdriver

Step 1: Aluminium Base

An aluminum or copper base is necessary as it dissipates heat much faster than iron.

it is used to attach to the led.

angles or panels can easily be straightened by few gentle strokes of hammer.

a thickness of 2mm and above will be preferred. cut its piece of approx. 1*1 inch.

Step 2: Led Attachment

use a super glue to attach led with aluminium which has less viscosity and dries too fastly this is good conductor as compared to some epoxy glues and makes a very thin layer.

I think so it is Cyanoacrylate

Step 3: Iron Strips

Use an old choke from tube light as it has got many wrought iron strips a screwdriver usually can open it up by some applied leverage.

Although iron is a bad conductor as compared to al but as you have increased surface area by using aluminum pieces so it will serve the purpose of heat dissipation into air well.
