Title (EN) PLANAR ILLUMINATION DEVICE
(FR) DISPOSITIF D’ÉCLAIRAGE PLAN
(JA) 面状照明装置
Abstract:
(EN) This planar illumination device according to an embodiment comprises a light source and a light guide plate (40). The light source emits light. The light guide plate (40) includes a side surface (40c), an emission surface (40e) being one main surface, and a back surface (40f) being the other main surface. A prism (40h) is formed on the back surface (40f), and light incident on the side surface (40c) from the light source is emitted from the emission surface (40e). Additionally, the prism (40h) includes a first region (40h1) substantially parallel to the emission surface (40e) and a second region (40h2) inclined with respect to the emission surface (40e), and the light source emits light (100) obliquely to the side surface (40c).
(FR) Ce dispositif d'éclairage plan selon un mode de réalisation comprend une source de lumière et une plaque de guidage de lumière (40). La source de lumière émet de la lumière. La plaque de guidage de lumière (40) comporte une surface latérale (40c), une surface d’émission (40e) qui constitue une surface principale, et une surface arrière (40f) qui constitue l’autre surface principale. Un prisme (40h) est formé sur la surface arrière (40f), et la lumière incidente sur la surface latérale (40c) émise en provenance de la source de lumière est émise à partir de la surface d’émission (40e). De plus, le prisme (40h) comprend une première région (40h1) sensiblement parallèle à la surface d'émission (40e) et une seconde région (40h2) inclinée par rapport à la surface d'émission (40e), et la source de lumière émet de la lumière (100) obliquement par rapport à la surface latérale (40c).
(JA) 実施形態の面状照明装置は、光源と、導光板(40)とを備える。光源は、光を出射する。導光板(40)は、側面(40c)と、一方の主面である出射面(40e)と、他方の主面である裏面(40f)とを有し、裏面(40f)にプリズム(40h)が形成され、光源から側面(40c)に入射される光を出射面(40e)から出射する。そして、プリズム(40h)は、出射面(40e)と略平行である第1領域(40h1)と、出射面(40e)に対して傾斜する第2領域(40h2)とを有し、光源は、側面(40c)に対して斜めに光(100)を出射する。
