To provide a luminaire with a video projection function that is more user-friendly.SOLUTION: A luminaire includes an illumination unit that emits illumination light, a projection type video display unit that emits video projection light for projecting a video, and a sensor capable of detecting an operation by an operation object with respect to a range including a video projection area of the projection type video display unit by performing light emission for operation detection used for operation detection, and the illumination light, the video projection light, and the operation detection light emission have different wavelength distribution characteristics, and an amount of light in the wavelength range of light used for operation detection by the sensor is configured such that a light amount of the operation detection light emission among the illumination light, the video projection light, and the operation detection light emission is the largest.SELECTED DRAWING: Figure 3 【課題】ユーザにとってより使い勝手が良い映像投射機能付き照明装置を提供する。【解決手段】照明光を発する照明ユニットと、映像を投射する映像投射光を発する投射型映像表示ユニットと、操作検出に用いる操作検出用発光を行い、前記投射型映像表示ユニットの映像投射領域を含む範囲について操作オブジェクトによる操作を検出可能なセンサーと、を備え、前記照明光、前記映像投射光、および前記操作検出用発光はそれぞれ異なる波長分布特性を有しており、前記センサーが操作検出で用いる光の波長域における光量は、前記照明光、前記映像投射光、および前記操作検出用発光のうち前記操作検出用発光の光量が最も大きくなるように構成する。【選択図】図３
