Originally started with using EL enabled outlet covers in the 1990's all over the old house.
Google electroluminescent wall plates and you will see the designs / patents.
This was what started me on endeavour. These were all 120VAC and didn't utilize inverters.
They used wires from the covers to the switch / outlet. Draw is supposed to be less than 35 mA per plate.
Sometime in the early 2000's found larger 120VAC plates, innocuous looking inches X inches and mounted them on the hallway outlets running wires to outlet and covered wire section with cover plate. You do not noticed them unless it is dark.
I googled the larger EL plates and they are still sold today but some $200 plus each one which personally is really expensive. I paid way less for these in the early 2000's.
Did find a more modern EL lamp incorporated in to the outlet.
The 120VAC connectivity is wires. Maybe because I am old fashioned and just do not like it or concerned maybe with arcing.
Personally feel that using wires is safer than this methodology of 120VAC for the LED lamps above.
That said they also have the mechanisms patented.
