NATURAL LIGHTING TOOL AND PANEL WITH NATURAL LIGHTING WINDOW
PROBLEM TO BE SOLVED: To provide a natural lighting tool suppressing light diffusivity from lowering due to external factors such as dew condensation or pollution.SOLUTION: A natural lighting tool includes: a light control member having a first surface to which light is incident, a second surface opposite to the first surface and from which the light emits, and a reflective surface present between the first surface and the second surface and configured to deviate the light incident from the first surface toward the second surface; and a light diffusion layer arranged on the second surface side of the light control member and configured to diffuse light therein. The haze value of the light diffusion layer is 30-80%.
【課題】 結露や汚れといった外的要因による光拡散性の低下が抑制された採光具を提供する。【解決手段】 本発明に係る採光具は、光が入射する第１面と、前記第１面に対向し光が出射する第２面とを有し、前記第１面と前記第２面との間に存在し、前記第１面から入射した光を前記第２面に向けて偏向する反射面と、を備えた光制御部材と、前記光制御部材の前記第２面側に配置され、内部で光を拡散する光拡散層と、を備え、前記光拡散層のヘーズの値が３０％以上８０％以下であることを特徴とする。【選択図】図３
