Forgive me if this is a dumb question, but … can’t you just shine the light in places where it won’t hit people? A wash of light that passes over people’s heads, between their cubicles, across vents and doors, but not shining directly on their skin and eyes? Presumably with a dark absorber at the other end. But it’s light; it goes in straight lines.
This is not a dumb question; you have just described upper room uv, which is an established, successful, and worthwhile tech. But it requires skilled labor to install (to avoid accidentally getting the angle wrong and blasting people in the head) and it does not have as much potential upside as newer tech.
