The illumination cover portion 7 of this embodiment is shown in FIG.
As shown in, the upper inclined portion 7b acts as a reflecting portion 15 that reduces the upwardly directed light M1 of the illumination unit U by reflection. That is, the upper inclined portion 7c can reflect the upward light M1 from the translucent portion 4c downward as reflected light M2 and efficiently illuminate the vicinity of the step board 21. As a result, as shown in FIG. 11, most of the illumination of the lighting unit U can be directed to the step board 21 of the stairs 2 to effectively illuminate the feet, and safety while walking can be ensured.
The upward light M1 that is likely to directly enter the eyes of a pedestrian is reduced to reduce glare. The inclination angle θ of the upper inclined portion 7b is preferably about 20 to 45 degrees with respect to the vertical line. And
It is particularly desirable to make the inclination angle of the upper inclined portion 7b larger than the inclination angle of the lower inclined portion 7c. Further, in this example, the reflecting portion 15 is composed of the upper inclined portion 7b formed of an inclined flat surface, but may be formed of, for example, a curved surface curved in an arc shape. On the other hand, the lower sloping portion 7c reflects the light N1 that is excessively downward to be reflected light N2 that is slightly upward,
It is possible to illuminate the upper surface of the step board 21 of the stairs 2 and achieve efficient illumination.
