I just want to confirm somthing. Is mineral oil truly nonconductive? It's not for liquid cooling, I want to submerge some LEDs in a filled bottle for an unusual light.
Well... Just try then.. Fill up a cup with the oil you want to use... then use a ohm meter.. og you could put some wires in it and an amperemeter.. be sure to use a short protected powersuply then...
It's a very good electrical insulator. Used to cool high-voltage transformers and as the dielectric in oiled paper capacitors. Or even for cooling one of these things. Try olive oil for a nice green tinge.
Well, it works fine. My lamp is done, now as soon as I find the cords to my camera, I'll post some pics.
here is a pic with the lamp on, but no flash on the camera: I wanted to do it with green LEDs firs, but I didn't have enoung/any that were bright enough to light up the bottle well. The results of this still aren't what I was hoping for. I wanted the oil to diffuse the light more. Anything I can add to it?
shake the bottle then? or find a tiny bit of clay and dissolve it.. but this COULD make the oil condictive....
Try sanding the led to get a diffuse dispertion from it, or mount the led near the top of the bottle, bright led s often have a narrow beam. Neat idea
