Japan has been rapidly adopting LED lighting for art galleries and museums due to its evolving color rendering properties and light emitting efficiency. Lighting designers Ryuichi Sawada and Tatsuya Iwai, responsible for four such lighting projects, introduce LED-related works in Japan at the Hoki Museum, Arts Maebash, the Heisei Chishinkan Wing of the Kyoto National Museum and the Tokyo Metropolitan Teien Art Museum. Each lecture addresses a different style of project, and attendees can expect to learn something about optimal LED lighting design in regard to each. Also covered will be matters of harmony in architecture and lighting, issues that arose in the process of design and construction and their resolution, and the reception the designs have received from the project owners, artistic staff, and visitors. Attendees can expect hints and inspiration that can be put to use in future exhibition space LED lighting projects.
