The lamellas are mutually interlocked during complete closing of the sunblind, and overlapped as a single piece. Photovoltaic elements for energy production are attached to an outer side of the sunblind. An organic LED display is equipped in an inner side of the sunblind. A control unit detects sun condition and electrically adjusts the lamellas such that solar radiation strikes perpendicular to the photovoltaic elements.

Description

To 1 .: sunscreen as a carrier for lighting and / or energy harvesting elements, characterized in that a sunscreen is used as a carrier for energy-saving lighting means.

As is well known in the building technology sun protection devices for shading the premises used. As also well known, each room also has separate lighting units, which are usually mounted on the ceiling. When it gets dark, usually the room lighting is switched on and the sunshade is completely closed to prevent the view from the outside.

In order to be able to shade a room in a building on the one hand and illuminate it on the other hand, two different technical facilities must be installed at the moment.

The specified in claim 1 invention is based on the problem to replace two separate technical facilities by a technical device.

This problem is solved by the features listed in claim 1.

The advantages achieved by the invention are that only a technical device is needed to darken a room and to illuminate it. Equipping a sunshade such as roller shutters, blinds or similar on the inside with modern energy-saving bulbs, eliminating the entire installation effort for conventional lighting and the artificial light always comes from the same direction as the natural light.

The sunshade device could, thanks to modern technology such. OLED displays, also be equipped with flat display modules, which would lead to the fact that the sunscreen could additionally be used as a screen.

The principle of equipping a sun protection device with energy-saving lamps or RGB-capable displays can be applied to all types of sun protection devices. These could be shutters blinds, shutters, slats for shading, blinds, pleats or the like may be the support material wood, aluminum, plastic, textiles or otherwise.

As an example, the inside of a blind is equipped with RGB-capable power-saving display modules. Each slat is equipped with its own display, which are interconnected via a central unit. In the bottom bar of the blind is also a row with super bright LED's. If it is too dark outside the blind can be lowered only a few centimeters, so that, in addition to the daylight, only the row with the LED's must be turned on. If the daylight is completely exhausted, the blind can be left completely lowered, so that the individual slats of the blinds are closed and form a closed surface inwards. When the light is switched on, the entire inner side of the blind shines and the room is illuminated by the window, which otherwise allows the natural light to enter the room.

If you use color-capable display modules for room lighting, you could choose any color to illuminate, simulate a sunset, or display any image. Even using it as a screen would be possible this way.

• 1.1: Das künstliche Licht kommt aus derselben Richtung wie tagsüber das natürliche Sonnenlicht.
• 1.2: Bei Verwendung von grossflächigen Leuchtmitteln, welche ein gleichmässiges Licht abgeben, kann die Raumausleuchtung annähernd wie bei Tageslicht sein.
• 1.3: Bei Verwendung von grossflächigen Leuchtmitteln, welche zugleich RGB-fähig sind, (jede beliebige Farbe wiedergeben können) könnten unterschiedlichste Lichtszenarien dargestellt werden.
• 1.4: Durch Verwendung RGB-fähiger Displays könnte die Sonnenschutzvorrichtung gleichzeitig als Bildschirm dienen.
• 1.5: Die Installation von herkömmlichen Leuchtmitteln kann entfallen, was vor allem bei neuen Objekten ein Einsparpotential bedeutet, da keine separaten Leerrohre, Kabel und Leitungen verlegt werden müssen.
• 1.6: Je nach verwendeter Beleuchtungstechnik wie z.B. OLED oder ähnliches sind diese auch dimmbar.

This approach offers the following advantages:

• 1.1 : The artificial light comes from the same direction as daytime natural sunlight.
• 1.2 : When using large-area lamps, which emit a uniform light, the room illumination can be approximately as in daylight.
• 1.3 : When using large-area light sources, which are also RGB-capable, (can reproduce any color) could be displayed a variety of lighting scenarios.
• 1.4 : By using RGB-enabled displays, the sunshade device could simultaneously serve as a screen.
• 1.5 : The installation of conventional bulbs can be omitted, which means a savings potential, especially for new objects, since no separate conduits, cables and lines must be laid.
• 1.6 : Depending on the lighting technology used, such as OLED or similar, these are also dimmable.

To 2 . Sunshade according to claim 1, characterized in that a sunshade is used as a carrier for elements which convert solar energy into electrical energy.

As is well known in the building technology sun protection devices only the benefit of shading and are usually used when an intense sun exposure is present.

As is also known from building services, in order to convert the energy of the sun into electrical energy, on facades or on roofs, usually photovoltaic elements are installed which are mounted at a fixed angle and do not automatically align with the sun.

The disadvantage of the existing solutions is also here that two separate technical facilities are needed. One for shading the premises and one for converting the energy of the sun into electrical energy.

The specified in claim 2 invention is also the problem here to replace two separate technical facilities by a technical device.

This problem is solved by the features listed in claim 2.

The advantages achieved by the invention are now that only a technical device is needed and thus the sunscreen and energy production can be combined by means of photovoltaics.

If you equip a blind on the outside with modern thin-layered photovoltaic elements for energy production, this has the further advantage that it can be aligned by an electronic control so that always an optimal efficiency can be achieved. This can be achieved by a sensor which detects the position of the sun and aligns the position of the individual slats of the blind so that the sun always impinges on this as perpendicular as possible.

The principle of using a sunscreen as a support for photovoltaic elements can be applied to all types of sunscreen. These could be shutters blinds, shutters, slats for shading, blinds, pleats or the like may be the support material wood, aluminum, plastic, textiles or otherwise.

The principle of using a sunscreen as a support for photovoltaic elements which can be additionally aligned automatically according to the Sun, can be transferred to all types of sunscreen which have a lamellar structure such as blinds, slats for shading, blinds, pleated or the like also here the support material may be wood, aluminum, plastic, textiles or other.

As an example, the outside of a venetian blind is equipped with elements for generating electrical energy from solar energy. A control unit is used for electrical adjustment of the blind. The control can thus be done in "manual" or "automatic" mode. In manual mode, the blind can be operated like a conventional blind and adjusted as desired. In automatic mode, however, the blind is always oriented so that the sun hits the photovoltaic elements as vertically as possible. As a result, the optimum efficiency is achieved while achieving good shading of the interior.

• 2.1: Immer dann wenn die Sonneneinstrahlung sehr intensiv ist und die Sonnenschutzvorrichtung zum Einsatz kommt besteht somit ein guter Wirkungsgrad.
• 2.2: Bei allen lamellenartigen Sonnenschutzvorrichtungen kann durch eine Steuereinheit, welche den Sonnenstand erfasst, eine elektrische Verstellung der Lamellen so stattfinden, dass die Sonne immer möglichst senkrecht auf die Photovoltaikelemente auftrifft und somit immer der optimale Wirkungsgrad gewährleistet ist.
• 2.3: Am Gebäude müssen keine separaten Photovoltaikelemente installiert werden, was optische Vorteile haben kann und sich auch als Kostenvorteil der in Patentanspruch 2 angegebenen Erfindung auswirken kann.

This approach offers the following advantages:

• 2.1: Whenever the sunlight is very intense and the sun protection device is used, there is thus a good efficiency.
• 2.2: In all lamellar sun protection devices can take place by a control unit, which detects the position of the sun, an electrical adjustment of the slats so that the sun always impinges as perpendicular as possible to the photovoltaic elements and thus always the optimum efficiency is guaranteed.
• 2.3: On the building no separate photovoltaic elements must be installed, which can have optical advantages and can also have a cost advantage of the invention specified in claim 2.

To 3 . Sunshade according to claim 1, characterized in that it is an optimal support for lighting and / or energy harvesting elements.

As is known, most sun protection devices used in building technology, such as e.g. Venetian blinds or shutters in the closed state no smooth surface, since the slats of a blind usually bent or z-shaped and the individual elements of a roller shutter also usually have a concave or convex shape. This has the disadvantage that in order to use these as a support for the elements mentioned in claim 1 and 2, an increased technical effort is needed.

Furthermore, cleaning of uneven surfaces is always more difficult than that of a homogeneous surface.

In addition, only shutters offer the possibility of complete blackout.

The indicated in claim 3 invention is based on the problem that flat surfaces are better suited to apply additional elements and align flat surfaces easier in a particular direction, which brings further advantages for the invention mentioned in claim 1 and 2.

Another problem with sun protection devices, which are not designed according to claim 3, is the increased cleaning effort and, except for shutters, the relatively large amount of residual light which penetrates into a completely closed state still in a room.

• Durch das Verwenden einer Jalousie, bei der die einzelnen Lamellen an der oberen sowie an der unteren Kante, jeweils auf der gegenüberliegenden Seite, eine Vertiefung aufweisen wird ermöglicht, dass die einzelnen Lamellen eine ebene Grundform besitzen und beim kompletten Schliessen gegenseitig ineinandergreifen bzw. ein Stück überlappen können um eine komplett geschlossene Oberfläche zu erhalten.

These problems are solved by the invention mentioned in claim 3 as follows:

• By using a Venetian blind, in which the individual slats on the upper and on the lower edge, respectively on the opposite side, have a depression allows the individual slats have a flat basic shape and interlock when fully closing each other or a piece can overlap to get a completely closed surface.

As an example, a Venetian blind for room lighting on the inside should be equipped with modern OLED displays and on the outside of the blinds photovoltaic elements are to be applied for energy.

Due to the straight basic shape of the individual slats, the blinds can be aligned during the day so that the sun always hits the slats at the optimum angle and a large area of the blind can ideally serve as a support for photovoltaic elements.

When the sun has set and the room is to be illuminated by an artificial light source, the special design of the slats allows the blind to serve as a uniform, large flat surface of the room lighting in the closed state.

• 3.1 Ein Aufbringen von Zusatzelementen wie Beleuchtungs- und/oder Photovoltaikelementen wird wesentlich erleichtert. Durch die glatte Oberfläche wird beim Aufbringen von Beleuchtungseinheiten die Effizienz der Raumausleuchtung verbessert. Der Wirkungsgrad bei der Anwendung als Träger für Photovoltaikelementen wird ebenfalls erhöht.
• 3.2: Durch die Verwendung von Lamellen, welche im Gegensatz zu den gebräuchlichen Lamellen nicht gebogen sind sondern eine gerade Grundform aufweisen, ergibt sich die Möglichkeit im komplett geschlossenen Zustand eine ebene Fläche zu realisieren. Diese ebene Fläche ist wesentlich leichter zu reinigen als die bekannten gebogenen Lamellen. Des Weiteren bietet eine ebene Fläche auch weniger Angriffsfläche für starke Winde was dazu führt, dass die Jalousie robuster wird.
• 3.3: Durch die Verwendung von Lamellen, welche an der oberen sowie an der unteren Kante jeweils auf der gegenüberliegenden Seite eine Vertiefung aufweisen wird ermöglicht, dass die einzelnen Lamellen beim kompletten Schliessen gegenseitig ineinandergreifen bzw. ein Stück überlappen können. Durch diese Überlappung wird es ermöglicht, den sonst üblichen Lichtspalt zu vermeiden, was im Gegensatz zur Verwendung herkömmlicher Jalousien zu einer besseren Abdunkelung des Raumes führt und die Vorteile einer Jalousie (Möglichkeit das einfallende Licht durch die Verstellung der Lamellen zu regulieren) mit denen eines Rollladens (Möglichkeit den Raum ganz abzudunkeln) kombiniert.

This approach offers the following advantages:

• 3.1 An application of additional elements such as lighting and / or photovoltaic elements is greatly facilitated. The smooth surface improves the efficiency of the room illumination when applying lighting units. The efficiency in the application as a carrier for photovoltaic elements is also increased.
• 3.2: By using lamellas, which are not bent in contrast to the conventional lamellae but have a straight basic shape, there is the possibility in the fully closed state to realize a flat surface. This flat surface is much easier to clean than the known curved blades. Furthermore, a flat surface also provides less exposure to strong winds, which makes the blind more robust.
• 3.3: The use of lamellas, which have a depression on the upper and lower edges on the opposite side, allows the individual lamellas to interlock or overlap one another when fully closed. This overlap makes it possible to avoid the usual light gap, which, in contrast to the use of conventional blinds to a better darkening of the room and the benefits of a blind (possibility to regulate the incident light by adjusting the slats) with those of a roller shutter (Possibility to completely darken the room) combined.

An embodiment which shows the basic shape of the slats according to claim 3, will be described by the drawing.
