We do! Sky lights, fiber optic sky light extenders, etc. humans are always trying to light up their artificial caves with sunlight.
Building architecture used to have amazing creative designs to capture this free lighting.
However, cheap efficient indoor lighting removed this as a driving force, so newer buildings don't have the same design constraints
I have never seen fiber optic sky light extenders in real life
Light extenders are fairly common in the UK - not fibre optic, but basically they look like if silvery tubes connected to a glass dome on the roof. Fairly common when a house extension leave a hall without a window.
They work on the principle of total internal reflection. Same as a fiber optic cable.
But they eventually leak so cheap LEDs it is.
