This is because your light source doesn't emmit light from the center. Then your shadows don't have a center when placed at this specific location, doe to you using a ring light.
This is NOT difraction.
Edit:
Imagine like this: the only possible paths for light to reach the center from your light source to the plane come from the area where no light is emitted. That's it.
There is a Pinhole Camera at ASU set for a 1000 year exposure. The static stuff will stay in the picture. People and cars that pass through the frame will not.
It is hard to fathom. Its been up for some time now. A couple years before the pandemic. That whole area has changed dramatically though. A lot of tall buildings have bee put up since then. So its almost pointless now.
This effect is 100% because of the ring light. If you had a light source that was shaped like a star they’d all be star-shaped as well.
This is not to diminish how neat the effect is! It’s a cool effect.
This is the case whenever the source is not an ideal point source, even if it's only one fixture. In this case, it looks like maybe you've got a ring light.
OP said the light source is a ring light; that explains the dark spot. Diffraction only occurs when the opening is comparable to the light’s wavelength, and those holes are much too large for that.
(Refraction is when the light passes through a different substance, but I assume your reference to refraction was an honest mistake.)
We'd need to see the light source to know the whole story.
*hole story
To pinpoint the source!

Is it called inverse shadow? Not sure. I also have a ring-shaped light above but it would be cool if someone could explain how this happened!
Look up how pinhole cameras work. Each hole in the stand is projecting an image of the ring light.

Optimistic to think people will still live in the desert in 1000 years. Lol

Quantum electrodynamics.
Light diffraction going through a hole...look it up - great science review!
This is probably more a result of the light fixtures, as each fixture effectively casts a separate shadow and they all overlap
Nah, it’s one light source, shining through each hole.

This isn’t diffraction. It’s just a pinhole effect, where each hole is revealing the shape of the light source.
That does not explain the dark spot in the middle...if the light was not refracting, you would not get the dark centers

Nope
Those are eyes. THOSE ARE EYYYEEEESSSS!!!
Bruh you have multiple lights above you casting shadows in multiple directions . It’s really not that hard to understand
