WAVELENGTH CONVERSION ELEMENT AND LIGHTING FIXTURE

To provide a wavelength conversion element that can improve fluorescent light utilization efficiency when being applied to a lighting fixture that includes a reflector.SOLUTION: A wavelength conversion element (10) includes: a substrate (1); and a fluorescent layer (2) disposed on the substrate (1). The fluorescent layer (2) includes a fluorescent light emission surface (2a) at a surface on an opposite side to a side of the substrate (1). A three-dimensional structure (3) for changing a fluorescent light emission angle is disposed on the fluorescent light emission surface (2a).SELECTED DRAWING: Figure 1 【課題】リフレクタを備える灯具に適用したときに、蛍光の利用効率を向上させることが可能な波長変換素子を提供する。【解決手段】波長変換素子（１０）は、基材（１）と、前記基材（１）上に配置された蛍光層（２）とを含み、前記蛍光層（２）は、前記基材（１）側と反対側の面に蛍光出射面（２ａ）を備え、前記蛍光出射面（２ａ）上に、蛍光の出射角度を変化させる三次元構造体（３）が配置されている。【選択図】図１
