To improve a function for awakening an attention to the surroundings by forming a light distribution pattern for road surface drawing without making a light distribution function defective in a lighting fixture unit comprising a reflection type spatial light modulator.SOLUTION: In a configuration that a front side of a unit is irradiated with light from a first light source 52A reflected by a spatial light modulator 30 via a projection lens 72, a second light source 52B is disposed at a position out of a plane including an optical axis Ax of the projection lens 72 and an emission center of the first light source 52A. While each of reflection elements 30As of the spatial light modulator 30 is located at a first angle position, the light from the first light source 52A is reflected toward the projection lens 72, and light from the second light source 52B is reflected in a direction out of the projection lens 72. While each of the reflection elements 30As is located at a second angle position, reverse reflections are performed. Thus, when forming a light distribution pattern for road surface drawing, a complementary light distribution pattern enclosing this is formable simultaneously.SELECTED DRAWING: Figure 1
