Using modern UV active pigments for indirect lighting? Answered
I am still living from boxes after moving house but I came to a small batch of very impressive UV active powder.
This new kind glows in the dark for at least a full night with good visability and usally it sold with the color name "auqa blue" - just don't be fooled by the old style pigments that only lasted for a fe minutes, I am taking about hours here....
The images and videos I tried with my SLR and phone are all terrible, seems they don't really like UV light :(
My thought was something like this:
Having a sufficient amount of pigment in the top coat of the wall or ceiling paint to allow for a nice glow.
Either on floor or ceiling level a row of UV LED's to allow for a quick charge of the pigments, or as an alternative once technology has caught up EL panels in the UV range with a pigment coating.
An area of 5x2cm is already enough as a "reading light" for several hours or to illuminate a map during night time hiking trips.
Also with the long after glow it would be quite possible to use "light transmission".
Here you have acrylic sheets on the outside walls or roof catching the light and transporting it to the inside.
So you could use natural light during the day that would also charge the pigments on wall or ceiling.
Of course this is not really feasable for home use unless you don't require any sleep but tunnels, bunkers, mines and such could benefit especially if using fibre optics to "transport" the light to where it is needed.
Another great idea (at least I think it is) would be to use these pigments on footpaths and sporting grounds.
Imagine a footpath that glows at night and illuminates where you go!
Or imagine a big factory during a power outage at night having clear walkways to direct the workers showing up all of a sudden on the floor...
Some quality pigments still allow for over 200 lumens after 60 minutes of recharge - this is in the region of a low power LED of modern technology.
I don't think a topic like this will qualify for a best answer but I would love to hear your thoughts and ideas on the topic of these modern after glow pigments.....
