Kawasaki Develops New LED Lighting and Air Purification Systems for Rolling Stock—Osaka Municipal Subway Midosuji Line 30000 Series to be the First to Feature the New Systems

Dec. 14, 2015

Tokyo, December 14, 2015—Kawasaki Heavy Industries, Ltd. announced today that the latest Osaka Municipal Subway Midosuji Line 30000 series cars, which are scheduled to go into operation in the fall of 2016, will feature Kawasaki’s newly developed LED lighting and air purification systems for rolling stock.

The new LED lighting system combines a proprietary indirect lighting fixture for rolling stock and the LED lighting technology of Sharp Corporation to achieve outstanding energy efficiency and passenger comfort. It will also be the first to adopt a cherry blossom-colored (somei-yoshino type)*1 light on a railway vehicle. The pale-pink light has the effect of reducing stress caused by being exposed to artificial light, as well as providing a sense of healing and being easy on the eyes.

The air purification system was developed jointly with DENSO Corporation and Sharp Corporation. It is the first such system for a commuter train car that comes equipped with Plasmacluster*2 technology. The system has an internal fan that enables air purification throughout the year without being affected by air conditioning. Its sleek design matches the urban feel of the interior.

Kawasaki will continue to leverage its superior technology and reliability in an effort to improve the environmental performance and passenger comfort of rolling stock.

*1 Cherry blossom-colored (somei-yoshino type) LED light was developed by Sharp Corporation.
