  For example, at night, a resident (user) of the house 10 turns on a power switch (not shown) of the LED light source 7. Thereby, as shown in FIG. 3, the LED light source 7 is lit (emitted).

  When the LED light source 7 is turned on (emits light), the light emitted from the LED light source 7 is reflected by the reflecting plate 3, guided to the window 103, and emitted (introduced) into the chamber 101 from the window 103. Then, the interior of the chamber 101 is illuminated. In this case, since the LED light source 7 is disposed on the reflecting plate 4 side, the light emitted from the LED light source 7 is reflected by the reflecting plate 3 and guided to the window portion 103, so that indirect illumination is obtained. . Thereby, an aesthetic effect and a healing effect (relaxation effect) are obtained.

  Further, the light emitted from the LED light source 7 is emitted to the outside of the house 10 from each through hole 31 of the reflection plate 3. Thereby, the feeling that there is a person in the house 10 can be given, and a crime prevention effect is obtained.

  Further, ventilation is performed between the outside of the house 10 and the inside of the optical duct 1 through each through hole 31 of the reflecting plate 3. Thereby, the inside of the optical duct 1 (space 21) can be ventilated, thereby preventing condensation in the optical duct 1 in winter.

  Further, when the window 103 is opened, ventilation is performed between the outside of the house 10, the inside of the optical duct 1, and the inside of the chamber 101 through the through-holes 31 of the window 103 and the reflection plate 3. Thereby, the inside of the chamber 101 and the inside of the optical duct 1 can be ventilated.

  As described above, the optical duct 1 has a number of functions including the function of a surface lattice.

  That is, first, sunlight can be freely taken into the room 101 (residential space).

  Moreover, the crime prevention effect is acquired, such as the intrusion into the room 101 (inside the house 10) from the window part 103 of an unwilling third party can be prevented.

  Further, the reflector 3 of the optical duct 1 and the side walls 5 and 6 function as blindfolds, and it is possible to prevent the inside of the chamber 101 from being viewed from the window 103.

Further, the reflector 3 is continuously spaced from the reflector 4 (outer wall 102) so that the gap distance L ₀ between the reflector 4 and the reflector 4 (gap distance L between the outer wall 102) is upward in the vertical direction. Since it is inclined with respect to the vertical direction so as to form a gradually increasing space 21, the size can be reduced as compared with the case where the reflector and the outer wall are parallel.

  Even when the optical duct 1 is attached to a relatively low position such as the first floor of the house 10, the optical duct 1 does not get in the way. For example, when the optical duct 1 is located near the boundary with the adjacent land, the optical duct 1 does not get in the way and easily passes when passing near the boundary with the adjacent land.

  In the present embodiment, the light emitted from the LED light source 7 is emitted to the outside of the house 10 from each through-hole 31 of the reflection plate 3. The light emitted from the light source 7 may be emitted from the daylighting unit 2 to the outside of the house 10, and each of the through holes 31 of the reflector 3 and the daylighting unit 2 may be used for the house 10. The light may be emitted to the outside.

  And in this optical duct 1, when the intermediate | middle layer 14 of the laminated board 12 is a sound absorption layer, a noise can be reduced. Therefore, it is not necessary to take noise measures (soundproof measures) such as using paired glass on the window 103 side.

  Moreover, when the intermediate | middle layer 14 is a heat insulation layer, the dew condensation etc. in winter can be suppressed. Therefore, it is not necessary to take heat insulation measures such as using a pair glass on the window 103 side.

  Moreover, when the intermediate | middle layer 14 is a nonflammable layer or a flame-resistant layer, the installation to the house constructed in a fire prevention area or a semi-fire prevention area is also attained. Moreover, although the part of the laminated board 12 has comparatively high fireproof property also when comprised only with a metal material, compared with it, heat conduction can be suppressed by the intermediate | middle layer 14, and fireproof property improves. Therefore, it is not necessary to take fire prevention measures such as providing a shutter on the window 103 side or using netted glass.

Further, when the intermediate layer 14 has two or more of the functions described above, the corresponding effects described above can be obtained.
Further, the present embodiment can be applied to each embodiment.
