To provide a lighting fixture capable of changing irradiation direction of light in which the width of change at the time of changing the irradiation direction can be made large, as well as the speed of changing the irradiation direction is increased.
The lighting fixture 1 is provided with an optical system member 2 which changes advancing direction of light and a variable light distribution light source 3 which can change the irradiation direction of light. The variable light distribution light source 3 includes a light-emitting part 4 which emits light. The variable light distribution light source 3 changes the irradiation direction of light emitted from the light-emitting part 4 and irradiates on the optical system member 2. By the optical system member 2, the width of change of the irradiation direction of light from the variable light distribution light source 3 can be made larger optically. Further, even if the change of width of the irradiation direction of light from the variable light distribution light source 3 is small, since the irradiation direction of light from the optical system member 2 can be changed greatly, the speed of changing the irradiation direction can be increased.
