Abstract
(EN) Provided is a diffused light control sheet (10) comprising: a louver layer (1) in which a light-transmission band (2) and a light-shielding band (3) are alternately and repeatedly provided; a transparent protective layer (4) provided on the first surface of the louver layer; and a light diffusion layer (5) provided on the second surface of the louver layer, the haze measured in accordance with JIS K 7136 (2000) of the light diffusion layer being 93% or greater.
(FR) L'invention concerne une feuille de régulation de lumière diffusée (10) comprenant : une couche de persienne (1) dans laquelle une bande de transmission de lumière (2) et une bande de protection contre la lumière (3) sont disposées en alternance et de manière répétée ; une couche protectrice transparente (4) disposée sur la première surface de la couche de persienne ; et une couche de diffusion de lumière (5) disposée sur la seconde surface de la couche de persienne, le trouble mesuré conformément à JIS K 7136 (2000) de la couche de diffusion de lumière étant supérieur ou égal à 93 %.
(JA) 光透過帯(2)と遮光帯(3)とが交互に繰り返して設けられたルーバー層(1)と、前記ルーバー層の第一面に設けられた透明保護層(4)と、前記ルーバー層の第二面に設けられた光拡散層(5)と、を備え、前記光拡散層のJIS K 7136(2000)に準拠して測定されるヘイズが93%以上である、拡散光制御シート(10)。
