Kuraray Co., Ltd.
Kuraray Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Masaaki Ito; “Kuraray”) has developed Japan’s first anisotropic emission light guide plates for controlling the direction in which light is emitted and capable of focusing it as needed to increase brightness. LED lighting using these light guides was recently installed in the soon to be opened new wing of Saijo Central Hospital in Ehime Prefecture.
Kuraray applied proprietary mastering technology to the creation of these light guide plates, forming intricate micron-level patterns into highly transparent methacrylic resin sheets.
The plates extracts light through both reflection and refraction, resulting in a light extraction efficiency rate of 93%.*1 Moreover, by allowing the precision control of the direction of emission, desired locations can be sufficiently illuminated.
Around 900 of these LED lightings have been installed in Saijo Central Hospital’s new wing, which will open on December 1, 2015. In addition to being installed to provide seamless lighting along the hospital hallways, they have been installed as illumination for patient beds. The resulting gentle brightness imparts a warm feeling. (Shimizu Corporation handled the hospital wing’s design and construction.)
This product is well suited for use in hotels, museums, stores, restaurants and other locations that need designer lighting in fixed spaces.
After five years: Annual sales of \1 billion (light guide plates)
