PROBLEM TO BE SOLVED: To provide a lighting fixture which can prevent a glare without lowering the amount of light of illumination light.SOLUTION: A lighting instrument 20 having a light source 21 and a reflection plate 24 is attached to a frame body 40 which is attached to an attached face 11, by an attachment metal fitting 30. Light from the light source 21 and light reflected by the reflection plate 24 are taken out of a light takeout part 33 of the lighting metal fitting 30 to a cone member 50 attached to the frame body 40, and emitted to a prescribed direction. A part of the light is applied to the light takeout part 33, however, since a tapered part 34 which is contracted in diameter toward the light emission direction is arranged at the light takeout part 33, the light applied to the light takeout part 33 is reflected at the tapered part 34. The tapered part 34 is made to reflect the light to a light emission side rather than a linear line L1 which connects a first point P1 at a light emission opening edge of the reflection plate 24 and a second point P2 opposing the first point P1 at a light emission opening edge of the cone member 50. By this, since the light applied to the tapered part 34 is not applied to the outside of the liner line L1, that is, the inside of a glare angle, the glare can be prevented without lowering the amount of light of the illumination light. |
