Title (EN) ILLUMINATION DEVICE
(FR) DISPOSITIF D'ÉCLAIRAGE
(JA) 照明装置
Abstract:
(EN) The present disclosure addresses the problem of providing an illumination device that can improve design freedom of an enclosure. The illumination device according to the present disclosure is provided with: an enclosure (2); a light source (80) provided in the enclosure (2); and an optical member (9) which is provided in the enclosure (2) and in which light emitted from the light source (80) is let in from an incidence surface (911). The enclosure (2) or the optical member (9) includes an emission surface (94) for emitting light that has passed through the optical member (9) to the outside of the enclosure (2). The area (S2) of the emission surface (94) is smaller than the area (S1) of the incidence surface (911).
(FR) La présente invention aborde le problème de la fourniture d'un dispositif d'éclairage qui peut améliorer la liberté de conception d'une enceinte. Le dispositif d'éclairage selon la présente invention comprend : une enceinte (2) ; une source de lumière (80) disposée dans l'enceinte (2) ; et un élément optique (9) qui est disposé dans l'enceinte (2) et dans lequel la lumière émise par la source de lumière (80) entre à partir d'une surface d'incidence (911). L'enceinte (2) ou l'élément optique (9) comprend une surface d'émission (94) pour émettre de la lumière qui a traversé l'élément optique (9) vers l'extérieur de l'enceinte (2). La superficie (S2) de la surface d'émission (94) est plus petite que la superficie (S1) de la surface d'incidence (911).
(JA) 本開示の課題は、筐体の設計上の自由度を向上することが可能な照明装置を提供することである。本開示に係る照明装置は、筐体(2)と、筐体(2)内に設けられた光源(80)と、筐体(2)内に設けられ、光源(80)から出た光を入射面(911)から入れる光学部材(9)と、を備える。筐体(2)又は光学部材(9)は、光学部材(9)を通った光を筐体(2)外に出す出射面(94)を有する。出射面(94)の面積(S)は、入射面(911)の面積(S)よりも小さい。
