LIGHT COLLECTING MEMBER AND LAMINATED GLASS WITH LIGHT CONTROLLING FUNCTION USING THE LIGHT COLLECTING MEMBER
PROBLEM TO BE SOLVED: To provide a light collecting member with a maintained visibility.SOLUTION: The light collecting member according to the present invention includes: a light transmission part 1 with a plurality of grooves in a surface; light controlling parts 2 in the grooves; and a buffer layer 3 on a surface near the light transmission part 1, the light transmission part 1 having a different index of refraction from that of the light controlling parts 2 and the maximum difference Tu in an ultraviolet transmission factor between the light transmission part 1 and the light controlling parts 2 satisfying the following formula (1) where T1 denotes the ultraviolet transmission factor (%) of the light transmission part 1 when the wavelength is W, T2 denotes the ultraviolet transmission factor (%) of the light controlling parts 2 when the wavelength is W, T3 denotes the ultraviolet transmission factor (%) of the buffer layer 3 when the wavelength is W, and the wavelength Wis a wavelength (nm) in the range of 250nm to 380nm which maximize the difference in the ultraviolet transmission factor between the light transmission part 1 and the light controlling parts 2.SELECTED DRAWING: Figure 1
【課題】視認性の低下を抑制することが可能な採光部材を提供する。【解決手段】一方の表面に複数の溝部を有する光透過部１と、溝部内に配置された光制御部２と、光制御部１が配置された側の表面上に配置された緩衝層３とを有し、光透過部１および光制御部２の屈折率が異なり、光透過部１および光制御部２の紫外線透過率の最大差Ｔｕが、下記式（１）を満たす。（Ｔ１は光透過部１の波長Ｗｍａｘにおける紫外線透過率（％）、Ｔ２は光制御部２の波長Ｗｍａｘにおける紫外線透過率（％）、Ｔ３は緩衝層３の波長Ｗｍａｘにおける紫外線透過率（％）である。波長Ｗｍａｘは、波長２５０ｎｍ〜３８０ｎｍにおいて、光透過部１の紫外線透過率と光制御部２の紫外線透過率との差が最大となる波長（ｎｍ）である。）【選択図】図１
