Physical interaction design DH2400

Problem:

Once testing our new multi coloured RGB LEDs, we ran in to some problems with the direction of the light. When mixing the different colours the red, green and blue light components all went in different, quite straight directions instead of blending in to one colour.

Solution:

We simply used sandpaper on them. The result was LEDs with more multidirectional light which made the different colours blend more smoothly together. Not perfect but a great improvement. One minor effect on the downside is that the light intensity decreased a notch.
