Problem To provide a lighting fixture that by varying beam angle of light emitted by a light source and beam angle of light to the exterior, is excellent in visual effect by indirect lighting, high in serviceability and safety of the light source, and applicable to a wide range of purposes. Means for Solving the Problem A configuration comprising a lighting fixture body of substantially L-shaped cross-section, a light source constituting a light radiation unit, a first reflector, a second reflector, and an opening constituting an illumination port, wherein the light source is installed at an innermost center region of the vertical lightguide section to face into the vertical lightguide section, the first reflector is installed obliquely near one corner of the vertical lightguide section and the lateral lightguide section, and the second reflector is obliquely installed near an endmost corner of the lateral lightguide section to face the first reflector.
