Luminaire. A complete lighting unit consisting of a light source such as a lamp or lamps, together with the parts designed to position the light source and connect it to the power supply. It may also include parts to protect the light source or the ballast or to distribute the light. A lampholder itself is not a luminaire.
A sign is not a luminaire. A sign is labeled at the factory where it was made. The label shall have the listing agency mark. The description you have provided tells me that 120volt power is fed to the led driver that is within the body of the sign. This will require a disconnect which can be a switch mounted on the sign. I would require an up close look inside the sign.
I have seen it mentioned here at the forum in other threads that SO cord is used as permanent wiring. I suspect that your inquiry as to whether the sign qualifies as a luminaire has to do with the SO cord. I would not allow a flexible cord run to a permanent sign.
