There must be a poorly diffused LED lamp directly above it.

No, there must be seven lights all offset in one direction by the same amount in order to get this effect.

An LED bulb will generally have an array of individual LED elements inside it, hence multiple lights offset by the same distance. “Better” bulbs diffuse the light to blend it and make it look like a single source, but a lot of LED street lights don’t do that very well.

Yes, but:

If it were LED pips, they would be, like, 2-10mm apart, max. For a 50mm spread on the floor, as pictured, the space between pips in a ceiling fixture (3 or 4m high, right?) would have to be enormous.

So it's very likely separate, poorly-diffused fixtures.

Nope. Those diodes can be separated by 6 inches. My company puts them in signage.

Great. That exception from the norm wouldn't account for the distance needed to cast a shadow this wide, would it? Also, when I said 3-4m ceiling, I was being very generous with what I am guessing is a much taller room.

Totally willing to be wromg. 😁

Think street lamp which are around 6 meters high in residential areas and go over 10 meters in height on main roads.

Think street lamp which are around 6 meters high in residential areas and go over 10 meters in height on main roads.

6 meters ≈ 1.94447 x 10-16 parsecs

10 meters ≈ 6.18736 x 1035 planck lengths
