Claims (4)

光源と、
前記光源の光軸に対して回転対称な面状の主反射板であって、後端開口と、当該後端開口より拡径された前端開口と、を有する主反射板と、
前記後端開口側に位置する第１端縁と、前記前端開口側に位置する第２端縁と、を有する平板状の副反射板と、
を備え、
前記光源は、前記後端開口から前記前端開口へ向けて光が発せられる様に配置されており、
前記光軸を通り、設置されたときに鉛直方向となる所定の断面において前記光源と前記前端開口の縁とを結ぶ仮想直線が前記副反射板を通る様に、前記副反射板は、前記光軸に対して傾けて配置されている、照明器具。 A light source;
A main reflector having a planar shape that is rotationally symmetric with respect to the optical axis of the light source, the main reflector having a rear end opening and a front end opening having a diameter larger than that of the rear end opening;
A flat sub-reflection plate having a first edge located on the rear end opening side and a second end edge located on the front end opening side;
With
The light source is arranged so that light is emitted from the rear end opening toward the front end opening,
The sub-reflecting plate has the light beam so that an imaginary straight line connecting the light source and the edge of the front end opening passes through the sub-reflecting plate in a predetermined cross section that passes through the optical axis and is vertical when installed. A luminaire placed at an angle to the axis. 前記所定の断面において前記第１端縁が前記仮想直線に接する様に、前記副反射板は配置されている、請求項１に記載の照明器具。   The lighting fixture according to claim 1, wherein the sub-reflector is disposed so that the first end edge is in contact with the virtual straight line in the predetermined cross section. 前記副反射板は、前記所定の断面において前記仮想直線と交差する様に配置されている、請求項１に記載の照明器具。   The lighting fixture according to claim 1, wherein the sub-reflecting plate is disposed so as to intersect the virtual straight line in the predetermined cross section. 前記第２端縁が前記前端開口内に位置する様に、前記副反射板は配置されている、請求項１〜３の何れか１つに記載の照明器具。   The lighting fixture according to any one of claims 1 to 3, wherein the sub-reflecting plate is arranged so that the second end edge is positioned in the front end opening.
