Japanese lighting designer Motoko Ishii is the art director of Sumitomo's booth and is showcasing several OLED chandeliers, including the OLED MINORI you see above. Motoko Ishii has been working with Sumitomo for a while now.
In addition to the OLED chandeliers, Sumitomo will also exhibit newly-designed OLED fixtures, co-developed with lighting fixture manufacturers. Some of these new fixtures will adopt Sumitomo's latest flexible OLEDs, for example the Crescent Moon and Ring EL you can see below, designed by Takayuki Nishizuka (Sou Design) and manufactured by Kishima.
Sumitomo has been developing its P-OLED materials and lighting panels for many years, and it seems that the company is finally able to start commercializing its technologies. Sumitomo is providing emitter materials for JOLED (who started low volume production of printed OLED monitor panels in December 2017) and is hopefully gearing up to start mass production of its own OLED lighting panels.
