Title (EN) INFRARED FOCUSING DEVICE
(FR) DISPOSITIF DE FOCALISATION INFRAROUGE
(JA) 赤外調光装置
Abstract:
(EN)  This infrared focusing device (111) is provided with an automatic control circuit (4) which, in accordance with a preset time schedule, performs control to switch between an infrared light reflecting state and transmitting state in a focusing cell (2). In so doing, the infrared light can be appropriately reflected or transmitted, without the cell itself heating up at times at which the infrared light is being reflected, and without infrared light exiting from the cell in an unintended direction.
(FR)  La présente invention porte sur un dispositif (111) de focalisation infrarouge qui comporte un circuit (4) de commande automatique qui, selon une programmation temporelle préréglée, réalise une commande pour passer entre un état de réflexion de lumière infrarouge et un état d'émission dans une cellule (2) de focalisation. Ce faisant, la lumière infrarouge peut être réfléchie ou émise de façon appropriée, sans que la cellule elle-même ne se réchauffe à des moments auxquels la lumière infrarouge est réfléchie, et sans que la lumière infrarouge ne sorte de la cellule dans une direction non prévue.
(JA)  本発明の赤外調光装置(111)は、予め設定されたタイムスケジュールに応じて、調光セル(2)における赤外光の反射状態と透過状態との切り替えを制御する自動制御回路(4)を備えている。これにより、赤外光の反射時に、セル自体を熱くすることなく、また、セルから意図しない方向へ赤外光を出射させることなく、赤外光を適切に反射・透過させることができる。
