Description
具体的には、光制御手段３の一方の面３ｂは、第１方向（Ｘ方向）の中央領域が第１方向と直交する第２方向（Ｙ方向）に拡散作用をする第１光制御部４を有する。更に第１光制御部４の第１方向の両端部が中央方向に集光性を有するフレネルレンズより成る第２光制御部５を有している。 Specifically, one surface 3b of the light control means 3, a first light control portion central region of the first direction (X direction) to the diffusing function in a second direction perpendicular to the first direction (Y-direction) 4. Further, both end portions of the first light control unit 4 in the first direction have the second light control unit 5 made of a Fresnel lens having a light collecting property in the central direction.
