Taisei Corporation, Okamura Corporation and Mitsubishi Heavy Industries, Ltd. (MHI) have jointly developed OLED desk lamps for office use. The newly developed OLED desk lamps will be installed in a Net-Zero Energy Building (ZEB)* verification facility that Taisei Corporation is constructing in the city of Yokohama. The OLED lamps, which emit soft light over a wide area, will be tested on an office-wide basis and are expected to reduce energy consumption while creating a more comfortable work environment.
