TOKYU CORPORATION JIYUGAOKA STATION主な設備●セラミック基板採用一体型LED照明器具●有機EL照明器具●照明制御システム●調色照明システム●多回路エネルギーモニタThe Lighting Project for Smart Model Jiyugaoka Station was adopted as an initiative supporting the “Challenge 25” campaign by Japan’s Ministry of the Environment. As part of this project, Tokyu Corpo-ration replaced all station lighting fixtures with highly efficient LEDs. In addition, some station facilities are using organic electroluminescent lights—the first of its kind installed for general lighting of a railway station in Japan. Energy saving on platforms is assisted by a timer programmed to conform to the yearly train schedule and a sophisti-cated light control system. This system combines illuminance sensors and human presence sensors to automatically adjust light intensity according to ambient brightness and congestion, as well as when a train approaches the station. For concourse lighting, a state-of-the-art control system adjusts color temperature and brightness of LEDs in sync with a circadian rhythm or a human bio-rhythm, providing both comfort and energy conservation. By implementing these control systems and adopting various energy-saving measures, Tokyu strives to reach its goal of reducing power usage for Jiyugaoka Station as a whole by 25 percent from the current level by fiscal 2012.Employing leading-edge lighting with advanced control systems東京都目黒区自由が丘東京急行電鉄株式会社東急テクノシステム株式会社2012年3月////所在地建築主電気工事竣工■東京急行電鉄株式会社 自由が丘駅色温度・明るさを自動制御するコンコース照明 ②色温度約4,700K(昼間)③色温度約4,000K(早朝、夕方~夜間) ④色温度約3,300K(夜間~深夜)空間の明るさ感指標「Feu」を照明設計に活用(大井町線ホーム)シミュレーション(蛍光灯)平均照度214 lx / Feu4.9シミュレーション(LED)平均照度221 lx / Feu4.8シミュレーション(LED+Feu)平均照度229 lx / Feu5.9運転士へのグレアを抑えつつ、Feu値を上げる配光制御を行ったホーム用照明器具タッチパネル採用の照明制御システム有機EL照明器具が設置されたシースルー改札口画像依頼画像依頼画像依頼④③②10
