I thought about how to do this a while back, but I couldn’t think of a good way to do it without it being huge, expensive, or a fire hazard. At the time, I do not think there were bright enough LEDs to really make this work, and I simply hadn’t thought of a good way to solve the Rayleigh scattering problem.
I also hadn’t thought of the trick with a bunch of boxes with separate LEDs. It seems like you could make a bunch of smaller versions of his larger one (that is, using smaller LEDs with reflective collimators and a layer of colloid for scattering), and get a similar effect without needing such a large volume. I may try this out.
What are your thoughts on DIYPerks’ recent artificial sunlight project?
This is really cool!
