LUMINAIRE

PROBLEM TO BE SOLVED: To provide a luminaire capable of preventing light from leaking to the outside while preventing life deterioration of a light source.SOLUTION: A luminaire includes: a light source which serves as a heat source; a lens oppositely arranged to the light source; a heat radiation fin thermally connected to the light source; a movement device for moving the light source and the heat radiation fin in a direction going toward the lens and a direction being separated from the lens within a predetermined range; a housing in which the light source and the movement device are arranged inside, and in which vent holes for causing the inside and outside to communicate with each other are formed in a range which is set in a direction being separated from the lens from a position opposing to a tip of the direction of the heat radiation fin going toward the lens in a direction orthogonal to the direction going toward the lens, in a state where the light source is arranged in a position closest to the lens in the predetermined range; and a light shielding structure for preventing light from leaking to the outside via the vent holes.SELECTED DRAWING: Figure 3 【課題】光源の寿命低下を防止しつつ、外部へ光が漏れることを防止可能な照明装置を提供すること。【解決手段】実施形態によれば、照明装置は、熱源となる光源と；前記光源に対向配置されたレンズと；前記光源に熱的に接続された放熱フィンと；前記光源及び前記放熱フィンを、前記レンズへ向かう方向及び前記レンズから離れる方向に所定範囲内で移動する移動装置と；前記光源及び前記移動装置を内側に配置する筐体であって、前記光源が前記所定範囲内で前記レンズに最も近づいた位置に配置された状態における前記放熱フィンの前記レンズへ向かう方向の先端と前記レンズへ向かう方向に直交する方向に対向する位置から前記レンズから離れる方向に設定された範囲に、内外を連通する通気孔が形成された筐体と；前記通気孔を通して光が外部へ漏れることを防止する遮光構造と；を備える。【選択図】図３
