I exercised my Google-Fu for “trade show booth lighting” (without quotes), that should get you started. You might also tack “frame” on the end.
My guess is that the lights are LED. Odds are the frame parts are modular, probably 4-6’ long sections. Nice stuff, looks like it wouldn’t be too difficult/heavy to move, especially if it’s aluminum, but a bit bulky for storage . . . says the woman with Stupid Amounts of gridwall (more than enough for a 10x20’ booth)!
