Ever since trying to print phosphor impregnated resin I wanted to try to print something to showcase this idea. So I thought, I could I print a flashlight?
I wanted to test the idea quickly so I developed a phosphor element that could fit inside a maglight.
The printed assembly is 2 part. A phosphor element and a light pipe hold. My hope is that the light travels up the the light pipe and activating the phosphor. The phosphor then would shine on the maglight reflector and the rest would work normally.
So how well does it work?
I would say that it was a slight susses. It did produce white light but it wasn’t very focused and the light pipe introduced too much blue to the maglight reflector.
I was curious what the lightpipe looked like by itself so:
and with the phosphor element:
To rap up I think there is some potential to optimize the prints to make this actually work. For my next attempt I don’t think I’m going to include a lightpipe. I think a thin file phosphor element would work better.
Please let me know what you think and any suggestions! I’m new to optics so I really am just taking stabs in the dark (pun intended).
