ILLUMINATION DEVICE

To provide an illumination device capable of improving uniformity of the brightness on an illuminated surface.SOLUTION: An illumination device includes a first light emitting part including a first optical part and a first light source part. The first optical part includes a first reflection part and a second reflection part. A first direction from the first reflection part to the second reflection part intersects with a second direction from the first light source part to the second reflection part. The direction from the first light source part to the first reflection part is along a first plane including the first direction and the second direction, and intersects with the second direction. The distance between the first reflection part and the first light source part is longer than the distance between the second reflection part and the first light source part. A light distribution angle in the first plane of first reflection part light of first emission light emitted from the first light source part that is reflected by the first reflection part is larger than a light distribution angle in the first plane of second reflection part light of the first emission light that is reflected by the second reflection part.SELECTED DRAWING: Figure 1 【課題】被照明面における明るさの均一性を向上可能な照明装置を提供する。【解決手段】実施形態によれば、照明装置は、第１光学部と、第１光源部と、を含む第１発光部を含む。前記第１光学部は、第１反射部及び第２反射部を含む。前記第１反射部から前記第２反射部への第１方向は、前記第１光源部から前記第２反射部への第２方向と交差する。前記第１光源部から前記第１反射部への方向は、前記第１方向及び前記第２方向を含む第１平面に沿い、前記第２方向と交差する。前記第１反射部と前記第１光源部との間の距離は、前記第２反射部と前記第１光源部との間の距離よりも長い。前記第１光源部から出射した第１出射光が前記第１反射部で反射した第１反射部光の前記第１平面内における配光角は、前記第１出射光が前記第２反射部で反射した第２反射部光の前記第１平面内における配光角よりも大きい。【選択図】図１
