...and the happy news is that this stuff is within the possibilities of current technology: make a computer-controlled array of LEDs, each LED producing a narrow frequency band. Given sufficiently powerful and narrow-banded LEDs, this kind of light source could simulate any spectrum.
Natural medicine freaks often complain that artificial lightning doesn't produce the same sensory response (and thus psychological well-being) as sunlight. Our fictional light-source could simulate any light condition, and even change during the day. We would be able to prove them right or wrong.
I've been bitching about this for quite some time, because I really want something like this. I'm glad others are thinking the same thought.
- tomsaffell 18y agoDoes sunlight induce 'psychological well-being' only by its energy in the visible spectra, or are there components outside the range to which eyes are sensitive that have an effect?
- jacobolus 18y ago> Given sufficiently powerful and narrow-banded LEDs, this kind of light source could simulate any spectrum. As far as I know, this is currently extremely unrealistic, if you're looking for something like a display. If you just want a light bulb type source, you could maybe do a rough approximation, very expensively. > complain that artificial lightning doesn't produce the same sensory response (and thus psychological well-being) as sunlight. It empirically does not produce the same sensory response. Psychological well-being is a bit harder to measure.
