I had some left over LED's from a previous project and decided to use them for the project. In the pictures below I used a lanyard from a conference I attended. It really didn't matter to me what the lanyard had on it, this project was more about creating the name badge using acrylic and a small LED light.
As you can see in the pictures, the LED we used had the capability of fading into about 3 different colors creating a fun and unique look. I bought the LED from this website if you are interested. http://www.extremeglow.com/store/p/32-Button-Body-Lights.aspx These LED's last up to 8 hrs before they need to be changed.
There are to many details involved to explain the entire project but in a nutshell I designed the acrylic piece to accept the LED light using AutoCAD. With a few measurements and engineering we engineered 7 pieces of acrylic to fit nicely together around the LED light. 5 of the pieces were clear acrylic and 2 of the pieces were black.
All in all it was a fun project and it turned out well.
