FIG. 11 is a perspective view showing a conventional illumination louver disclosed in Japanese Patent Publication No. JP-A-2004-32069, and FIG. 11 is a side view showing a partial cross section of an illumination fixture on which the illumination louver is mounted. In the figure, the illumination louver 1 is made of a plurality of strip board-shaped paperboards, and is made of the same strip board-shaped paperboard as the first louver material 2 in which a plurality of perforations are formed in the vertical direction. The second louver material 3 on which the perforations are formed is glued to form a plurality of lattice-shaped light transmission ports 4
Is formed. 5 is the first louver material 2 and the second
It is a cross-joint portion of the louver material 3. The louvers 1 for illumination are folded by applying an external force to the first louver material 2 alternately in the longitudinal direction of the first louver materials 2 from opposite directions.
When the both ends of the folded illumination louver 1 are pulled outward, they are restored to their original rectangular shape.

も有する。Further, the fluorescent tube supported in a state of being inserted in the fluorescent tube supporting holes formed in the plurality of flat plate portions of the louver for illumination has a partial portion which is a part of the flat plate portion and the bent portion. Since it is shielded and the flat plate and bent parts are semi-transparent,
The light from the fluorescent tube, which is shielded by the flat plate and part of the bent part, is semi-indirectly transmitted and can be diffused to provide a smooth surface illumination.By changing the expansion of the louver for illumination, the light distribution can be achieved. Also has the effect of being adjustable. Further, the louver for illumination is constructed by alternately bending the heat-resistant hard synthetic resin plate to form a bent portion, and forming fluorescent tube supporting holes in a plurality of flat plate portions of the hard synthetic resin plate. Because
It has a simple shape, easy processing, low cost and light weight, and excellent heat resistance and durability. Furthermore, since the fluorescent tube is partially shielded by the flat plate portion and a part of the bent portion, half of the whole is open, and the shielded half is open on both sides, so that the ventilation is good,
It also has an effect that the heat of the fluorescent tube can be released to the outside.
