よび交差ルーバ１０も同様な材料を使用できる。The luer 3 is provided in the light-guiding opening 5. The louver 3 has a plurality of main louvers 8 arranged at predetermined intervals at substantially the same height as each other, and a sub louver 9 provided between these main louvers 8 and having a lower height than the main louvers 8.
The lower end of the sub louver 9 is disposed above the lower end of the main louver 8. The main louver 8 and the sub louver 9 have their light sources 1 on their upper ends at substantially the same height, and the sub louver 9 is located on one side of the main louver 8 facing each other as shown in FIG. They are offset and arranged parallel to each other. Further, the light source 1 and the lamp socket 4 are arranged such that the lamp socket 4 side of the light source 1 is not close to the main louver 8 and the sub louver 9 with respect to the arrangement direction of the light source 1 and the lamp socket 4.
Further, as shown in FIG. 2, an intersecting louver 10 having the same height as the main louver 8 is arranged in a direction orthogonal to the main louver 8. The main louver 8, the sub louver 9, and the cross louver 10 are respectively equal in height and have a vertical posture. These louvers are integrally attached to the frame portion 17 and are composed of an outer frame 20 also serving as a main louver 8 at the end, a main louver 8 held by the outer frame 20, and a sub louver 9. Since the frame portion 17 is detachably attached by the magic spring 16, the frame portion 17 is detachably attached to the light-guiding opening 5 of the device main body 2, and around the axis of the light-guiding opening 5 in the opening direction. 18
It can be mounted in the inverted state rotated by 0 °. Although the frame 17 and the outer frame 20 are made of wood, they may be made of plastic or metal. The same material can be used for the main louver 8, the sub louver 9, and the cross louver 10.

The distance between the opposite side wall of the outer frame 20 and the main louver 8 facing the side wall. As described above, L 1 = L 2 = L 3
It is. L 4 represents a distance between one side wall of the outer frame 20 opposite the spacing, L 5 and auxiliary louver 9 and the main louver 8 between the sub louvers 9 close to the main louver 8, L as described above 4 <
L is 5. L is equal to the distance between the side walls of the frame portion 17 and the intersection louver 10 and the distance between the intersection louvers 10;
And L 1 = L. θ is a light shielding angle with respect to the lamp axis, for example, about 68 °, and is equal to each of the main louvers 8 and the sub louvers 9. However, the light-shielding angle (not shown) in the opposite direction is, as is clear from the figure, the main louver 8.
It is equal to the light-shielding angle due to only

The mounting position of the luminaire is substantially above the base 22a of the foot of the patient 22 with the patient lying on the bed. As a result, when the light shielding angle is 68 °, the light of the light source 1 does not directly enter the eyes of the patient 22.

き、ルーバ同志の輝度むらが少ない。Since the lamp socket 4 does not emit light, the apparatus main body 2 is darkened.
Are separated and the louver opening is large,
Light can be emitted almost uniformly from any of the louver openings, and there is little luminance unevenness among the louvers.

This is because, in the first embodiment, the height of the auxiliary louvers 9a to 9c is set such that a light shielding angle that blocks direct light from the light source 1 from an imaginary point A below the instrument, for example, near the eyes of the patient 22, can be secured. From the lamp socket 4 side to the non-lamp socket side. That is, the height of each sub-louver 9 is sequentially set from the sub-louver 9c on the front end side of the light source 1 to the sub-louver 9a on the lamp socket 4 side, and L 6 , L 7 ,
When L 8 is L 6 <L 7 <L 8 . In this case, the light beam at the light-shielding angle by each sub louver 9 is converged at the point A as shown in FIG. Other configurations are the same as those of the first embodiment.
