Sep. 26, 2016

Sumitomo Chemical’s polymer OLED lighting will be adopted for "JEWELRY JARDIN", a chandelier in the restaurant "Goodday" in Yomiuri Land, Tokyo's largest amusement park in Inagi City, Tokyo.

The "JEWELRY JARDIN" chandelier is designed for Yomiuri Land by Motoko Ishii, the world-renowned lighting designer known for various accomplishments of lighting at a number of project sites, including Tokyo Tower. "JEWELRY JARDIN" uses polymer OLED lighting panels developed by Sumitomo Chemical, and the decorative lighting symbolizes a "Garden in the Sky," creating a space of beauty by numerous colors of light.

Organic lighting overview

The OLED lighting is an illuminant made from an electricity-conducting organic material, emitting light when a voltage has been applied. The emitting color varies depending on the molecular structure of an organic material used. An OLED that is
made from a polymer as a light emitting material is called a Polymer OLED.


OLED JARDIN is a lighting object designed by Motoko Ishii and uses polymer OLED lighting panels developed by Sumitomo Chemical. It was exhibited at Light+Building 2016. Light+Building, which is held biennially in Frankfurt, Germany, is one of the world’s largest trade fair for lighting and building technology.
