Title
(EN) PLANAR ILLUMINATION DEVICE
(FR) DISPOSITIF D'ÉCLAIRAGE PLAN
(JA) 面状照明装置
Abstract
(EN) A planar illumination device (1) of one embodiment comprises: a bottom frame (3); a recess (7b); a center pin (11); and a fixing part. The bottom frame (3): has a floor section (3a) and a side wall (3b) which is erected on a peripheral edge of the floor section (3a); and accommodates a light guide plate (7). The recess (7b) is provided in approximately the center of the light incidence side of the light guide plate (7). The center pin (11) is erected on the floor section (3a), and is fit with the recess (7b). The fixing part fixes the light guide plate (7) to the bottom frame (3) within the range of a predetermined distance from the center pin (11) on the light incidence side of the light guide plate (7).
(FR) La présente invention concerne un dispositif d'éclairage plan (1) qui, selon un mode de réalisation, comprend : un cadre inférieur (3) ; un évidement (7b) ; une broche centrale (11) ; et une partie de fixation. Le cadre inférieur (3) : présente une section plancher (3a) et une paroi latérale (3b) qui est dressée sur un bord périphérique de la section plancher (3a) ; et reçoit une plaque de guidage de lumière (7). L'évidement (7b) est disposé approximativement au centre du côté d'incidence de lumière de la plaque de guidage de lumière (7). La broche centrale (11) est dressée sur la section plancher (3a), et est ajustée avec l'évidement (7b). La partie de fixation fixe la plaque de guidage de lumière (7) au cadre inférieur (3) dans la plage d'une distance prédéfinie par rapport à la broche centrale (11) sur le côté d'incidence de lumière de la plaque de guidage de lumière (7).
(JA) 実施形態の面状照明装置(1)は、ボトムフレーム(3)と、凹部(7b)と、センターピン(11)と、固定部とを備える。前記ボトムフレーム(3)は、床部(3a)と、該床部(3a)の周縁に立設された側壁(3b)とを有し、導光板(7)を収容する。前記凹部(7b)は、前記導光板(7)の入光側の辺の略中央に設けられる。前記センターピン(11)は、前記床部(3a)に立設され、前記凹部(7b)と嵌合する。前記固定部は、前記導光板(7)の入光側の辺の前記センターピン(11)から所定の距離の範囲内において、前記導光板(7)を前記ボトムフレーム(3)に固定する。
