Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lighting fixture capable of irradiating light in a desired direction and making a fine adjustment of irradiation direction even in the case there is a limitation in an installation space.SOLUTION: Light emitted from an LED chip 33 mounted on an LED mounting board 34 is irradiated on an optical lens 40 in the front in irradiation direction. Since the optical lens 40 has a prism pattern 42 installed in parallel, the light irradiated on the optical lens 40 is irradiated by being refracted in a prescribed direction. Thereby, even in the case there is a limitation in the installation space, light can be irradiated in a desired direction by using an ordinary lighting fixture. Further, since the optical lens 40 can be rotated, the irradiation direction of light can be adjusted and also, since a display part 43 for showing the irradiation direction of the optical lens 40 is provided, the irradiation direction can be easily grasped.
