This is a LED umbrella. It is clear with LEDs on the umbrella holders, and uses neo pixels. it is pretty cool, because at night you cant see the the umbrella because its clear plastic, only the surrounding lights of the umbrella.
This is pretty simple actually. All it uses is a clear umbrella fitted with LED lights on the support wires.

This relates to engineering because you use LED sensors to make the umbrella and have to attach them to a clear umbrella, and cover them up, so they don’t get wet in the rain.
