There has been proposed a light control glass window utilizing the fact that the transparency of the liquid crystal changes due to (see, for example, Patent Document 1).

しかし前記特許文献１の調光ガラス窓では、太陽電池は調光ガラスが取り付けられていない窓枠の下辺部分に配設されているように、太陽電池を配設するためのある程度の面積
を持った配設場所を必要とし、そのため太陽電池の配設場所に制約があり、また太陽電池を窓毎に一々取り付ける必要があり、さらに太陽電池が窓枠から突出しているために見栄えもよくない。 However, in the light control glass window of the said patent document 1, it has a certain area for arrange | positioning a solar cell so that a solar cell is arrange | positioned in the lower part part of the window frame to which the light control glass is not attached. Therefore, there is a restriction on the location of the solar cell, and it is necessary to attach the solar cell to each window, and the solar cell protrudes from the window frame, so that it does not look good.

本発明は、上記のような点に鑑み、太陽電池の配設場所を必要とせず、従って配設に際して配設場所や見栄えについて考慮する必要のない自動調光用ガラス素材を提供することを目的とする。   An object of the present invention is to provide a glass material for automatic light control that does not require an installation location of a solar cell and therefore does not need to consider the installation location and appearance at the time of installation in view of the above points. And

上記目的を達成するために、本発明の自動調光用ガラス素材は、液晶ガラス２と透明な太陽電池１を両側から透明なガラス板３で挟み込んだ形状を持つことを特徴とする。   In order to achieve the above object, the glass material for automatic light control of the present invention is characterized by having a shape in which a liquid crystal glass 2 and a transparent solar cell 1 are sandwiched between transparent glass plates 3 from both sides.

It consists of a transparent divided solar power that faces the surface.

本発明によれば、液晶ガラスと太陽電池とを一体にしたことにより、この自動調光用ガラス素材を取り付ける場合に、従来のように太陽電池の配設場所や見栄えについて何ら考慮する必要が無く、通常のガラスと同様に取り付けることができる。
また液晶ガラスと透明な太陽電池をそれぞれ任意の小区画に分割したものとすることにより、区画毎にきめ細かく自動調光することができる。
さらにこの自動調光用ガラス素材を窓ガラスとした場合、紫外光は透明な太陽電池に吸収されるので、人体に有害な紫外光の室内への侵入を防止できる。 According to the present invention, since the liquid crystal glass and the solar cell are integrated, when the glass material for automatic light control is attached, there is no need to consider the location and appearance of the solar cell as in the past. Can be attached in the same way as normal glass.
Further, by dividing the liquid crystal glass and the transparent solar cell into arbitrary small sections, it is possible to perform automatic light control finely for each section.
Furthermore, when this automatic light control glass material is used as a window glass, ultraviolet light is absorbed by a transparent solar cell, so that ultraviolet light harmful to the human body can be prevented from entering the room.

本発明を実施するための最良の形態を実施例に基づき図面を参照して説明する。   The best mode for carrying out the present invention will be described based on an embodiment with reference to the drawings.

図１は実施例１の自動調光用ガラス素材の側断面図である。
１は透明な太陽電池で、例えば非特許文献１に開示されているように太陽光のうちの紫外光を吸収して発電し、可視光及び赤外光を透過するものである。２は液晶ガラスで、液晶を封入した２枚の透明ガラス板の内面に形成した薄膜状の透明電極に印加される電圧に応じて光の透過量が変化するものである。
なお自動調光用ガラス素材としてみたとき、上記の太陽電池１は太陽光が入射する側に配置され、液晶ガラス２はその反対側（内側）に配置されるので、入射する太陽光は先ず透明な太陽電池１を通過し、ここで紫外光による発電が行なわれ、透明な太陽電池１を透過した可視光と赤外光が液晶ガラスに到達することになる。
３は上記の透明な太陽電池１と液晶ガラス２とを挟み込んだ透明ガラス板である。
上記の薄膜状の透明電極には電圧を印加するためのリード線を接続することができる。 FIG. 1 is a side sectional view of the glass material for automatic light control according to the first embodiment.
Reference numeral 1 denotes a transparent solar cell, for example, as disclosed in Non-Patent Document 1, which absorbs ultraviolet light in sunlight and generates electric power and transmits visible light and infrared light. Reference numeral 2 denotes liquid crystal glass, and the amount of transmitted light changes according to the voltage applied to the thin film-like transparent electrode formed on the inner surface of the two transparent glass plates enclosing the liquid crystal.
When viewed as a glass material for automatic light control, the solar cell 1 is disposed on the side on which sunlight is incident, and the liquid crystal glass 2 is disposed on the opposite side (inner side). The solar cell 1 passes through the solar cell 1 and is generated by ultraviolet light. Visible light and infrared light transmitted through the transparent solar cell 1 reach the liquid crystal glass.
A transparent glass plate 3 sandwiches the transparent solar cell 1 and the liquid crystal glass 2.
A lead wire for applying a voltage can be connected to the thin film-like transparent electrode.

本発明で用いる液晶ガラスとしては二種類あり、その１は、電極間に電圧が印加されないときは液晶が透明に保たれ、電極間に電圧が印加されるときは液晶が不透明になり、かつ印加する電圧の大きさに応じて不透明の度合いが変化するもの（所謂、ノーマルホワイトで、ＴＮ液晶が用いられる。）であり、その２は、上記とは逆に、電極間に電圧が印加されるときは液晶が透明に保たれ、電極間に電圧が印加されないときは液晶が不透明になり、かつ印加する電圧の大きさに応じて不透明の度合いが変化するもの（所謂、ノーマルブラックで、高分子分散型液晶が用いられる。）であり、用途に応じて使い分けされる。   There are two types of liquid crystal glass used in the present invention. One is that the liquid crystal is kept transparent when no voltage is applied between the electrodes, and the liquid crystal becomes opaque when a voltage is applied between the electrodes. The degree of opacity changes according to the magnitude of the voltage to be applied (so-called normal white, TN liquid crystal is used). In the second case, a voltage is applied between the electrodes, contrary to the above. When the liquid crystal is kept transparent, when no voltage is applied between the electrodes, the liquid crystal becomes opaque, and the degree of opacity changes according to the magnitude of the applied voltage (so-called normal black, polymer Dispersed liquid crystal is used.), Which is used according to the application.

即ち、例えばガラス窓からの入射光が少ない場合は透明のままにしておき、入射光が強くなるに応じて不透明の度合いを強くして入射光を遮断したい場合には、上記のその１の液晶ガラスが用いられ、これにより太陽光が強い場合に強さに応じて透過光量を自動調整することができる。
逆に外が明るいときは透明にしてガラス窓から採光し、外が暗くなって外からの視線を遮断したい場合には、上記のその２の液晶ガラスが用いられる。これは、日中は開け、夕方以降は閉めるカーテンの代用となり、カーテンのように一々開け・閉めする必要が無い。 That is, for example, when the incident light from the glass window is small, it is kept transparent, and when it is desired to block the incident light by increasing the opacity as the incident light becomes stronger, the first liquid crystal Glass is used, and when the sunlight is strong, the amount of transmitted light can be automatically adjusted according to the strength.
On the other hand, when the outside is bright, it is made transparent so that it is taken from the glass window, and when the outside becomes dark and it is desired to block the line of sight from the outside, the second liquid crystal glass is used. This is a substitute for a curtain that opens during the day and closes after the evening and does not need to be opened and closed like a curtain.

いずれの場合も、電極間に印加する電圧は透明な太陽電池から得られる発電電圧を利用するが、太陽電池の発電電圧の大小は光量（透明な太陽電池の場合は紫外光の光量）の大小に応じて変わる（即ち、入射する光量が大であれば発電電圧が大きく、入射する光量が小であれば発電電圧が小さい。）ので、それを利用して入射光の遮断量を制御することができる。
なお実際に本発明の自動調光用ガラス素材を用いて液晶ガラスの透明度を制御する場合には、二次電池又は大容量のコンデンサを含む電源回路、マイコン、ドライバ、操作パネル、リモコン等を含む適宜の制御手段が必要である。 In either case, the voltage applied between the electrodes uses the power generation voltage obtained from the transparent solar cell, but the power generation voltage of the solar cell is the amount of light (in the case of a transparent solar cell, the amount of ultraviolet light). (That is, the generated voltage is large if the amount of incident light is large, and the generated voltage is small if the amount of incident light is small). Can do.
In addition, when actually controlling the transparency of the liquid crystal glass using the glass material for automatic light control of the present invention, it includes a power supply circuit including a secondary battery or a large-capacitance capacitor, a microcomputer, a driver, an operation panel, a remote control, etc. Appropriate control means is required.
