Zusammenfassung: | To provide an illumination device capable of reducing luminance unevenness.SOLUTION: An illumination device 1 is composed mostly of a panel 2 that has an illumination area 23 illuminated by illumination light 31, a light source 3 that outputs the illumination light 31, and a light guide 5 that is disposed so as to intersect an optical axis 30 of the light source 3 between the panel 2 and the light source 3, has a center part 53 having a shape scattering the illumination light 31 to lower the brightness of a center area 23a of the illumination area 23 on at least one of an upper surface 50 and a lower surface 51, and a peripheral part 54 having a shape reflecting the illumination light 31 toward a peripheral area 23b surrounding the center area 23a.SELECTED DRAWING: Figure 1
【課題】輝度ムラを低減することができる照明装置を提供する。【解決手段】照明装置1は、照明光31によって照明される照明領域23を有するパネル2と、照明光31を出力する光源3と、パネル2と光源3の間であって光源3の光軸30と交差するように配置され、照明光31を拡散して照明領域23の中央領域23aの輝度を下げる形状を上面50及び下面51の少なくとも一方に有する中央部53、及び中央領域23aを囲む周辺領域23bに向けて照明光31を反射する形状を有する周辺部54を有するライトガイド5と、を備えて概略構成されている。【選択図】図1 |
