Diffusing Leds the Fast Way

From Just in Time

For my Led Cube project I needed diffused (opague) leds. And I didn't have any. On the instructables pages you can find instructions how to sand your leds by hand. There it is mentioned that it takes about 5 minutes per led. I don't have that kind of time (or patience) to spend 64x 5 minutes. So I went on a 'Home Improvenent' mission to use some power tools to diffuse my leds.

First step: make a fitting for the led. I used a wood plug. Wood is good, plastic might tear apart or melt sooner. The wood needs to be kinda hard too; after about 50 leds the holes seemed to widen. LedandPlug1.jpg

Second step: drill two holes in the plug using preferably a 0.8mm (or 0.7mm) drill. A PCB drill bit will likely be that size. LedPlugHoles.jpg

Third step: saw through the plug, so the led pins can come out of the bottom and the led can sit to the top of the plug tightly LedInPlug.jpg

Fourth step: get the power drill and fit the plug in. PlugInDrill.jpg


Instead of sanding paper I used a sanding sponge, because that could adjust to the shape of the led very well. It takes about 10 seconds per led to diffuse it. DiffusedLed.jpg

Here are the diffused result and the clear original compared: DiffusedCompared.jpg
