  • Once again a great job! About your search for nanoparticles I too could find nothing. However, nanofluids are all the rage now in high end custom loops using a variety of different elements. You would however need to agitate the fluid to stop the particles from falling out of suspension. Hope you find what you're looking for!

  • Why not simply carefully removing a bit of the phosphor-coating of the led, as white light leds originally are producing already blue light and the other wavelength are the result of reradiation of blue light energy at shorter wavelength by the phosphor-coating? To get the diffusion effect, than add a simply light dispersion solution. But probably I missed some practical points…

    Dominic KyritsisDominic Kyritsis6 أيام قبل
    • I think you want the main (and slightly yellowed) light to be the only linear bit, and the blue "sky" to be non linear diffused light

  • Sunlight is one thing, but radiant heat is also very appealing, Is there any heat radiated from the LED, Probably very little. Mounting a parabolic infrared this side of the glass may work.

  • Hi, i enjoyed your artificial sunlight project so much that i thought of doing it myself but wondered if there was a way to make the equivalent effect with a plastic prism to disperse the light and at the same time get the blue effect from the pastic, this could be set in a flat mirror like structure to hang on a wall like a artificial window, what do you think? love the ideas thanks, Phill

  • This is wonderful! I have been long thinking about better ways to create artificial illumination and you explained it so well that it sounds almost easy. I wonder if the quality of the artificial sunlight would improve if you put additional water tanks with different concentrations of soap to simulate the varying concentration of air molecules across the different layers of the atmosphere.

  • You should preload outside light intensity and translate it to LED intensity, so when the sun is up also led intensity will change.

  • Very good. Now put it on a gimbal system so you can freely direct the angle of the parallel rays coming through your window and simulate the sun angles at different latitudes and times of year and day progression cycles. Some days you might fancy a Scandinavian low-angle sun; other days you might prefer the sun more vertically overhead for a Mediterranean or tropical feel.

  • What does it look like with your significantly lower-powered, "Recommended" 100-Watt LED? I like your video but I have a hard time believing the effect will be nearly as impressive with a similar light-source that utilizes 1/5 of the power compared to the one you said you used in the video. Is there any part of your video (or other video) that utilizes the 100-watt light-source for this same, exact purpose? I wouldn't mind doing a similar project, myself.
