Interchange IKlj so that the maximum beam angle of light distribution is different from
It is formed into an L-shaped prism pattern. For example, if the irradiation pattern (8) for the ceiling height is 31 m1 and the floor is 2- as shown in Figure 3, the corner of the square irradiation pattern (8) is 1111e115 side 1.

By making the prism surface (7) (7) (7) (7) into the prism pattern shown in Figure 3, the light from the center of the light source section of the lamp (3) has a maximum peak A of 5 as shown in Figure S&I and Figure SM. The light is controlled at an angle of +18.4°.
