However, with the above skylight device, if the lighting dome is transparent, direct sunlight will enter the room, so
When your skin is exposed to direct sunlight, it can make you feel hot, especially in the summer when the sun is strong.
The temperature inside the room rises too much, causing considerable pain. On the other hand, when the interior is illuminated at night, the entire interior can be seen through the lighting dome, so if the interior is adjacent to a high-rise residential building, there is a risk of people peeking into the interior at night, which poses a problem in terms of protecting privacy.

つた。 Under these circumstances, recently, skylight devices incorporating skylight blind devices have been developed and are being installed in some residential buildings. As such a blind device, for example, there is a structure in which a light-blocking curtain is manually opened and closed, but this device is large-scale and does not have a very good appearance, and furthermore, there is a problem that opening and closing the light-blocking curtain is surprisingly troublesome.

In order to solve the above problems all at once, the skylight device of the present invention uses a transparent resin film with transparent electrode layers formed on both sides of a liquid crystal layer made of a transparent resin matrix and a liquid crystal compound, on the underside of a synthetic resin daylighting dome. It is characterized by providing a wired glass plate to which a light control film laminated on the transparent electrode layer side is adhered.

In a skylight device having such a configuration, when a voltage is applied to the transparent electrode layer formed on the transparent resin film of the light control film, the light control film changes due to the electro-optic effect of the liquid crystal layer made of the transparent resin matrix and the liquid crystal compound. Depending on the type of liquid crystal, it changes from transparent to opaque or cloudy and semitransparent, and vice versa, from opaque or cloudy and semitransparent to transparent. Therefore, if the light control film is transparent, the light that enters from the lighting dome will pass through the light control film and be taken indoors.
It can brighten the indoor space, and conversely, if the light control film is made opaque in cases where direct sunlight enters, the light control film blocks the light that enters from the daylighting dome, thereby preventing direct sunlight. can do. Also,
When the light control film becomes cloudy and translucent, scattered light enters the room, making it possible to prevent direct sunlight and brighten the room.
一方、夜間において調光膜を不透明又は白濁半

となり、汎用性や作業性が良好なものとなる。 In addition, since the light control film is attached to the wired glass plate, the wired glass plate prevents flames and sparks from spreading to neighboring houses even if the synthetic resin daylighting dome softens and collapses due to the heat of a fire. Furthermore, since the transparent electrode layer is formed on a transparent resin film and laminated on both sides of the liquid crystal layer, the light control film attached to the wired glass plate is thin and can be easily adjusted to the size of the wired glass. It becomes possible to make them match and stick them together, resulting in good versatility and workability.

As schematically shown in the figure, a liquid crystal compound 1 is placed in a transparent resin matrix 14 such as polyvinyl alcohol, acrylic resin, epoxy resin, urethane resin, etc.
It has a structure in which particles 5 are dispersed as approximately spherical droplets, and the thickness thereof is approximately 10 to 100 μm. This liquid crystal formulation 15 includes, for example, cyanobiphenyl,
Containing liquid crystal molecules 15a such as pyrimidine, or the liquid crystal molecules 15a and dichroic dyes (not shown) such as azo and anthraquinone, both transparent electrode layers 13a,
When no voltage is applied across 13c, the liquid crystal molecules 15a (or liquid crystal molecules and dye) are free and irregularly oriented as shown in FIG. As shown in FIG. 3B, the liquid crystal molecules 15a (or the liquid crystal molecules and the dye) are aligned along the electric field.

れ、満足な採光が行われる。 The skylight device with the above configuration is based on the lighting dome 1
When you want the daylighting dome 1 to be transparent, such as in the morning and evening when there is no direct sunlight, turn on the switch 19.
Then, a voltage is applied between the transparent electrodes 13a and 13c of the light control film 13. When a voltage is applied in this way, if the liquid crystal compound 15 of the liquid crystal layer 13b contains liquid crystal molecules 15a and does not contain dye, the liquid crystal molecules 15a
are oriented along the electric field as shown in FIG.
Since the refractive index of the liquid crystal layer 13b is substantially the same as that of 4, the liquid crystal layer 13b becomes transparent because they are optically the same or similar substances. Therefore, the light incident from the lighting dome 1 passes through the light control film 13 and is taken into the room, thereby providing satisfactory lighting.
これに対し、直射日光が入る昼下がりのように

で、白濁度を自由に可変調節することもできる。 On the other hand, when you want to make it translucent, such as in the early afternoon when direct sunlight enters, turn switch 19 OFF.
However, no voltage is applied between the transparent electrode layers 13a and 13c. In such a state where no voltage is applied, the liquid crystal molecules 15a are irregularly oriented as shown in FIG. The light incident on the liquid crystal composition 15 is scattered or refracted at the interface between the liquid crystal composition 15 and the resin matrix 14 and enters the liquid crystal composition 15.
5, and light comes out in all directions. Therefore, the liquid crystal layer 13b becomes cloudy and translucent like ground glass, and scattered light enters the room, so it is not exposed to direct sunlight, and even in midsummer, the user can stay comfortably indoors without feeling the heat. Moreover, since the amount of daylight itself hardly changes, the interior does not become dark unlike conventional skylight blind devices. Also, at night, if the light control film 13 is made cloudy and semi-transparent as described above,
There is no need to worry about people looking into the room from outside, so you can fully protect your privacy. Further, when the applied voltage is adjusted by the variable resistor 20, the liquid crystal molecules 15a are oriented according to the strength of the electric field, so that the white turbidity can be freely adjusted.
一方、液晶層１３ｂの液晶配合物１５が液晶分

夜間には屋内が完全に見えなくなる。 On the other hand, if the liquid crystal compound 15 of the liquid crystal layer 13b contains liquid crystal molecules 15a and a dye, the switch 19 is turned off.
When turned on, the liquid crystal molecules 15a are oriented in the direction of the electric field, and the dye is also oriented in the same direction, and the transmitted light is no longer absorbed by the dye, so the light control film 13 becomes colorless and transparent, but when the switch 19 is turned off, Then,
Both the liquid crystal molecules 15a and the dye are oriented irregularly, and the dye absorbs light and is strongly colored, so the light control film 13 becomes colored and opaque, blocking light. Therefore, direct sunlight is blocked by the light control film 13, and the interior is completely invisible at night.
尚、上記のような偏光板不要の調光膜１３にお

光膜を形成する場合は、スイツチ１９のON・
OFF操作を上記と逆転させる必要がある。 In addition, in the light control film 13 that does not require a polarizing plate as described above, it is also possible to use a DS type liquid crystal element, and in that case, when a voltage is applied between the transparent electrode layers 13a and 13c, the liquid crystal layer 13b becomes cloudy. However, when no voltage is applied, it becomes transparent. Therefore, when forming such a light control film, turn ON/OFF the switch 19.
It is necessary to reverse the OFF operation to the above.
また、調光膜を網入りガラス板に貼着すること
により、火災等の熱で採光ドームが軟化崩壊して

火の粉が隣接家屋に飛び火する心配がなく防災効
果が十分となる。 In addition, by attaching the light control film to the wired glass plate, the wired glass plate will not break even if the lighting dome softens and collapses due to the heat of a fire, so flames and sparks will not spread to neighboring houses. There is no need to worry and the disaster prevention effect is sufficient.
