“…19) Since a long-range WPT circuit was first demonstrated with a 60 W light bulb, 2) WPT systems for lighting applications were reported using LED, 20) fluorescent lamps, 21) and OLED. 22,23) Wireless driving of the dispersion type or powder EL is beneficial, as the high voltage (>100 V) power cable is not necessary, which enhances the safety and reliability of the lighting system. The use of the powder EL in the WPT system can also realize a flexible sheet-like light source without a power connection.…”

A wireless power transfer circuit was developed for an inorganic EL device. When transmission and receiver circuits are both in resonant mode, low operating voltage of 30 V was enough to achieve the EL luminance as high as 180 cd/m2. As for the transmission and the receiver coils, different types and shapes are studied to clarify those effects on the EL luminance and transmission efficiency. Solenoid coils generally presented higher luminance than other types. Polygonal solenoid coils resulted in even higher luminance and transmission efficiency than circular solenoids. A spiral or a spider coil, in which air core area is much smaller than the solenoid coil, was found to less sensitive to coil displacement. The difference in EL performances with variation of coils suggests the possibility of further improvement the WPT system.
