Известно устройство светозащиты окна, содержащее тонкие, прозрачные стенки из листового стекла или подобного материала, отделенные друг от друга небольшим зазором, который заполнен суспензией, содержащей мелкие частицы, и источник энергии с проводами (GB 1385505, 26.02.1975).  A device is known for the protection of a window containing thin, transparent walls made of sheet glass or similar material, separated from each other by a small gap, which is filled with a suspension containing fine particles, and an energy source with wires (GB 1385505, 02.26.1975).
Недостатком данного устройства низкая эффективность по регулировке уровня затемнения, яркости, сложность в эксплуатации и наличие «зеркального эффекта».  The disadvantage of this device is low efficiency in adjusting the level of darkening, brightness, difficulty in operation and the presence of a “mirror effect”.
Техническая проблема, на решение которой направлена предложенная полезная модель, заключается в необходимости расширения арсенала устройства светозащиты окна, параметры, характеристики которого обеспечивают расширение функциональных возможностей за счет регулировки уровня затемнения, обеспечения контроля количества света, проходящего сквозь окна, и устранение «зеркального эффекта».  The technical problem addressed by the proposed utility model is the need to expand the arsenal of the window lighting protection device, the parameters whose characteristics provide enhanced functionality by adjusting the dimming level, ensuring control of the amount of light passing through the window, and eliminating the “mirror effect”.
Технический результат, достигаемый при реализации данной полезной модели, заключается в повышении эксплуатационных характеристик устройства светозащиты окна за счет регулировка уровня/степени затемнения, яркости и устранения бликов.  The technical result achieved in the implementation of this utility model is to improve the operational characteristics of the window light-shielding device by adjusting the level / degree of dimming, brightness and eliminating glare.

Вертикальный фильтр представляет собой поляризатор, пропускающий только вертикально ориентированный свет.  The vertical filter is a polarizer that allows only vertically oriented light to pass through.

Они могут быть встроенными в корпус питаемых устройств или выполняться в виде отдельных устройств). The power source is autonomous (can be powered from the on-board network — for example, cars) or mains (when powered from the network, special sources of secondary power are used — network adapters. They can be built into the case of powered devices or performed as separate devices).
Прозрачные электроды выполнены сплошными и содержат прозрачный проводящий слой, причем для электродов можно использовать любой тип прозрачных проводящих пленок, например, пленка In203 (ITO - Indium Tin Oxide).  The transparent electrodes are solid and contain a transparent conductive layer, and any type of transparent conductive films can be used for the electrodes, for example, an In203 film (ITO - Indium Tin Oxide).
Данное конструктивное выполнение устройства (модуля) светозащиты окна обеспечивает возможность регулировки уровня/степени затемнения, яркости и устраняет блики, что повышает эксплуатационные характеристики (улучшает технические характеристики устройства светозащиты окна) и расширяет область применения заявленной полезной модели в остеклении любых типов окон и дверей в строительной области и автомобилестроении.  This constructive implementation of the device (module) of window light protection provides the ability to adjust the level / degree of dimming, brightness and eliminates glare, which improves performance (improves the technical characteristics of the window light protection device) and expands the scope of the claimed utility model in glazing of all types of windows and doors area and automotive.
Сущность полезной модели поясняется чертежом, на котором изображен общий вид устройства светозащиты окна.  The essence of the utility model is illustrated in the drawing, which shows a general view of the device of light protection of a window.
Устройство светозащиты окна представляет собой слоистую структуру, заключенную в металлический каркас по периметру, и может быть выполнено в виде триплекса. Устройство светозащиты окна содержит стекла 1 с нанесенными на них изнутри сплошными прозрачными электродами 2, подключенными к источнику питания 7.  The device of light protection of the window is a layered structure enclosed in a metal frame around the perimeter, and can be made in the form of triplex. The device of the light shielding of the window contains glass 1 with solid transparent electrodes 2 attached to them from the inside, connected to the power source 7.
Прозрачный электрод 2 представляет собой пленку-проводник (токопроводящий слой). Между прозрачными электродами 2 размещен жидкокристаллический слой 5, представляющий собой жидкокристаллическую матрицу (ЖК-матрицу, TN-матрицу (Twist Nematic)) из полимера с жидкими кристаллами, например PDLC или LCD.  The transparent electrode 2 is a conductor film (conductive layer). Between the transparent electrodes 2 is placed a liquid crystal layer 5, which is a liquid crystal matrix (LCD matrix, TN matrix (Twist Nematic)) of a polymer with liquid crystals, such as PDLC or LCD.
Один из прозрачных электродов 2 подключен к источнику питания 7 через реостат 6.  One of the transparent electrodes 2 is connected to the power source 7 through the rheostat 6.
Прозрачный электрод 2 вместе со стеклом 1 образуют пару (электрод-стекло), в каждой такой паре между стеклом 1 и электродом 2 размещен фильтр с определенным угол поляризации.  Transparent electrode 2 together with glass 1 form a pair (electrode-glass), in each such pair between glass 1 and electrode 2 a filter is placed with a certain angle of polarization.
В одной из пар «стекло-электрод» размещен горизонтальный фильтр 3 (поляризатор, пропускающий только горизонтально ориентированный свет), в другой паре «стекло-электрод» расположен вертикальный фильтр 4 (поляризатор, пропускающий только вертикально ориентированный свет). Таким образом устанавливаются фильтры, имеющие перпендикулярные углы поляризации для поглощения света, то есть направление оси поляризации последующего фильтра расположено под прямым углом к оси поляризации предыдущего фильтра. Если бы жидких кристаллов между фильтрами не было, то свет, пропускаемый первым фильтром, практически полностью блокировался бы вторым фильтром. A horizontal filter 3 is placed in one of the glass-electrode pairs (a polarizer that transmits only horizontally oriented light), and the other glass-electrode pair has a vertical filter 4 (a polarizer that transmits only vertically oriented light). In this way, filters are installed that have perpendicular polarization angles to absorb light, that is, the direction of the polarization axis of the subsequent filter is at right angles to the polarization axis of the previous filter. If there were no liquid crystals between the filters, the light transmitted by the first filter would be almost completely blocked by the second filter.
В основе работы устройства лежит принцип поляризации света на основе двух фильтров (светофильтров) и жидких кристаллов.  The device is based on the principle of light polarization based on two filters (light filters) and liquid crystals.
Жидкокристаллический слой, представляющий собой жидкокристаллическую матрицу, относится к пассивному типу индикатора, который модулирует внешний световой поток под действием электрического поля или тока. Работа жидкокристаллической матрицы основана на использовании эффекта вращения плоскости поляризации света слоем закрученного наматического ЖК-материала (твист- эффект).  The liquid crystal layer, which is a liquid crystal matrix, refers to a passive type of indicator that modulates the external light flux under the action of an electric field or current. The operation of the liquid crystal matrix is based on the use of the rotation effect of the plane of polarization of light by a layer of a twisted namatic LC material (twist effect).
Поверхность электродов, контактирующая с жидкими кристаллами, специально обработана для изначальной ориентации молекул в одном направлении и представляет собой пленку-проводник (прозрачный проводящий слой), на внутренней стороне которой нанесен рисунок электродов адресации и в качестве которого может быть использована пленка Ih203 (ITO - Indium Tin Oxide). В качестве основы (подложек) прозрачных электродов может быть использована стеклянная пластина толщиной до 1 мм. В TN-матрице указанные направления взаимно перпендикулярны, поэтому молекулы в отсутствие напряжения выстраиваются в винтовую (спиралевидную) структуру из молекул ЖК-материала. Эта структура преломляет свет таким образом, что до второго фильтра плоскость его поляризации поворачивается и через него свет проходит уже без потерь. То есть поток света проходит через горизонтальный фильтр (первый фильтр/поляроид), при этом часть светового потока, не имеющего азимутальной поляризации, теряется на упомянутом фильтре, а остальной поток, уже поляризованного света, проходит через слой ЖК-материала, поворачивает плоскость поляризации на 90° и ориентация плоскости поляризации этого потока теперь совпадает с плоскостью поляризации вертикального фильтра (второго фильтра/поляроида), и поток проходит через него почти без потерь. Если не считать поглощения первым фильтром половины неполяризованного света, ячейку можно считать прозрачной. The surface of the electrodes, in contact with liquid crystals, is specially processed for the initial orientation of the molecules in one direction and is a conductor film (transparent conductive layer), on the inner side of which a pattern of addressing electrodes is applied and as which Ih 2 0 3 film can be used ( ITO - Indium Tin Oxide). A glass plate with a thickness of up to 1 mm can be used as the base (substrates) of transparent electrodes. In the TN matrix, the indicated directions are mutually perpendicular, therefore, in the absence of voltage, the molecules are arranged in a helical (spiral) structure of molecules of the LC material. This structure refracts light in such a way that before the second filter its polarization plane rotates and the light passes through it without loss. That is, the flow of light passes through a horizontal filter (first filter / polaroid), while a portion of the luminous flux that does not have azimuthal polarization is lost on the said filter, and the rest of the stream, already polarized light, passes through the layer of the LCD material, turns the plane of polarization on 90 ° and the polarization plane orientation of this flux now coincides with the polarization plane of the vertical filter (second filter / polaroid), and the flux passes through it almost without loss. Apart from the absorption by the first filter of half unpolarized light, the cell can be considered transparent.
Если же к электродам приложено напряжение, то молекулы стремятся выстроиться в направлении электрического поля, что искажает винтовую структуру (спиралевидная структура в слое ЖК-материала разрушается и теряет свойства дву лучепреломления). При этом силы упругости противодействуют этому, и при отключении напряжения молекулы возвращаются в исходное положение. При достаточной величине поля практически все молекулы становятся параллельны, что приводит к непрозрачности структуры. Таким образом проходящий через жидкокристаллический слой поток света не изменяет плоскость поляризации и почти полностью поглощается в вертикальном (втором) фильтре, плоскость поляризации которого смещена на 90° по отношению к плоскости поляризации светового потока. If voltage is applied to the electrodes, then the molecules tend to line up in the direction of the electric field, which distorts the helical structure (the spiral structure in the layer of the LC material is destroyed and loses the properties of birefringence). In this case, the elastic forces counteract this, and when the voltage is turned off, the molecules return to their original position. With almost all molecules become parallel to a sufficiently large field, which leads to an opacity of the structure. Thus, the light flux passing through the liquid crystal layer does not change the polarization plane and is almost completely absorbed in the vertical (second) filter, the polarization plane of which is shifted by 90 ° with respect to the polarization plane of the light flux.
Наличие в устройстве реостата позволяет регулировать силу тока от которой пропорционально зависит и сила магнитного поля, которое в свою очередь влияет на положение в пространстве жидких кристаллов (ЖК). Варьируя напряжение, можно управлять степенью прозрачности (меняется проникновение световой волны от 0% до 100%).  The presence of a rheostat in the device allows you to adjust the strength of the current on which the magnetic field strength is proportional, which in turn affects the position of the liquid crystals in space. By varying the voltage, you can control the degree of transparency (the penetration of the light wave varies from 0% to 100%).
Если постоянное напряжение приложено в течение долгого времени, жидкокристаллическая структура может деградировать из-за миграции, ионов. Для решения этой проблемы применяется переменный ток или изменение полярности поля при каждой адресации ячейки (так как изменение прозрачности происходит при включении тока, вне зависимости от его полярности).  If a constant voltage is applied for a long time, the liquid crystal structure may degrade due to the migration of ions. To solve this problem, an alternating current or a change in the polarity of the field is applied at each addressing of the cell (since the change in transparency occurs when the current is turned on, regardless of its polarity).
Во всей матрице можно управлять каждой из ячеек индивидуально, но при увеличении их количества это становится трудновыполнимо, так как растёт число требуемых электродов. Поэтому практически везде применяется адресация по строкам и столбцам.  In the entire matrix, each of the cells can be controlled individually, but with an increase in their number, this becomes difficult because the number of required electrodes increases. Therefore, addressing in rows and columns is used almost everywhere.
Таким образом, устройство дополнительно может состоять из высокоточной электроники, обрабатывающей входной сигнал напряжения, ЖК-матрицы (монохромной или полихромной), источника (блока) питания и корпуса с элементами управления.  Thus, the device can additionally consist of high-precision electronics processing the input voltage signal, an LCD matrix (monochrome or polychrome), a power source (block) and a housing with control elements.
Полезная модель может быть выполнена как одной ячейкой, так и в виде сочетании множества ячеек.  A utility model can be performed as a single cell, or as a combination of a plurality of cells.
