Description

The invention relates to an illuminated facade system.

The invention is concerned with the lighting of facades. In addition to lights that are mounted on the facade and illuminate the facade, LED panels are known from the prior art that can be mounted on facades and make a facade glow in the dark.

However, such LED panels are expensive and complex to assemble and are therefore not suitable for large-area equipping of large facades of commercial buildings and other large buildings.

It is true that lighting systems for facades have been proposed in the past; However, they do not enable large facades to be equipped with lighting systems in an economical manner. For example shows WO 2017/140937 A1 a system in which a support profile (8) is first attached to a wall or a metallic support structure (E). On the support profile (8) are then two - to be connected to each other via a U-profile - support profiles (1), which in connection with a further profile (2) clamp plate elements (3), which are illuminated at the front with lighting elements (5) will. Due to the large number of components and profiles required, this system is not suitable for the cost-effective equipping of large facade areas with a lighting system.

US 2012/0194895 A1 shows another facade system, which is not suitable for accommodating LED arrangements, since no protective channel is available for such LED arrangements.

KR 10 2010 0 008 305 A shows another system, which, however, is unsuitable for the cost-effective equipping of large facade systems with lighting, since when a single screw (4) is fastened a large number of components, in particular plate elements (8, 9), LED arrangements ( 12th , 14th ) together with the associated profiles and other profiles (3), must be brought into position and held, which is technically complex and complex.

The invention is therefore based on the object of developing illuminated facade systems so that large facades can be equipped economically with such illuminated facade systems.

The invention solves this problem with the features of an illuminated facade system according to claim 1.

The illuminated facade system according to the invention has a profile arrangement which has a facade-side, in particular one-piece, carrier profile and a one-piece or multi-part clamping profile, the facade-side carrier profile being designed to be mounted on the outer wall of a building or an existing facade system and at least one to wear at least partially or completely translucent plate element. The clamping profile can be connected, in particular releasably connected, for example screwed or riveted, to the carrier profile with the formation of several channels in such a way that the profile arrangement has an upper channel for accommodating an upper LED arrangement and / or a lower channel for accommodating a lower LED arrangement and a Has cable duct for accommodating electrical lines for the LED assemblies. An upper plate element and / or a lower plate element can be clamped between the clamping profile and the carrier profile in such a way that the lower edge of the upper plate element is opposite the upper LED arrangement and / or the upper edge of the lower plate element is opposite the lower LED arrangement.

In this way, according to the invention, a plate element can be illuminated over its edges by means of LED arrangements. The plate element can be, for example, a glass plate or an acrylic glass plate, for example single-pane safety glass; preferably the plate element is printed with ceramic screen printing. The LED arrangements advantageously have a circuit board on which LED elements with several colors, in particular red, green and blue, are arranged, so that a wide color spectrum can be displayed by mixing these colors. Since the LED arrangements run along the edges of the plate elements, uniform illumination of the plate elements is guaranteed. The lighting can be varied both in color and in intensity, in particular also over the length of the respective LED arrangements.

The profile arrangement according to the invention makes it possible to first mount support profiles on the outer wall of a building or an existing facade system, in particular a mullion-transom facade system together with LED arrangements, and then, step by step, insert a plate element and clamp it with a clamping profile.

In one case, e.g. in the case of a new post-and-beam facade, this replaces carrier profile according to the invention, the clamping profile of a conventional mullion-transom facade system. In another case, for example in the case of retrofitting on a post-and-rail facade already present on the building, the support profile according to the invention is screwed onto the clamping profile together with the cover of the existing post-and-rail facade. Alternatively, in the case of retrofitting, the clamping profile of the existing post-rule facade system can be replaced. This has the advantage that the structural depth remains small, which can be advantageous in particular for reasons of space. The support profile according to the invention can be fastened with - in particular self-tapping - screws in the horizontal transom of the existing post-rule facade system.

In this way, in the case of the illuminated facade system according to the invention, the facade-side, in particular one-piece, support profile is advantageously mounted directly on the outer wall of a building or on an already existing facade system. The illuminated facade system according to the invention requires only a few components and profiles in this way. The small number of components and profiles allows, on the one hand, a cost-effective production of the facade system and, on the other hand, an assembly of the facade system with only a few work steps. The facade system according to the invention is therefore particularly suitable for economically equipping large facade areas. The illuminated facade system according to the invention can be flexibly adapted to any building size, since only the plate elements have to be manufactured in the correct dimensions, while the profile arrangements can be manufactured as a mass product. If necessary, they are to be cut to length. Mass production allows inexpensive machine production while at the same time observing high quality standards. Human error due to a high proportion of manual processing is therefore very unlikely. This is particularly advantageous when installing illuminated facade systems on large and tall commercial buildings, the facades of which are generally only accessible with great effort; usually the entire building has to be provided with scaffolding. A high quality of the components used is therefore desirable. Due to its simple structure, the invention allows the required components to be manufactured industrially and therefore guarantees a long service life with high quality even under extreme weather conditions such as sun, wind, moisture, heat and cold.

In addition to an essentially complete, full-area illumination of a building, the solution according to the invention also allows only individual, in particular horizontal, strips of illuminated plate elements. Therefore, the carrier profile and the clamping profile can be designed in such a way that a plate element can only be held in one direction. It is therefore not absolutely necessary for plate elements to be clamped in both directions, upwards and downwards.

According to a further development of the invention, the upper channel is delimited at the top by an upper translucent profile and / or the lower channel is delimited at the bottom by a lower translucent profile. These translucent profiles protect the LED arrangement and allow a plate element to be supported with its entire weight on such a translucent profile without the adjoining LED arrangement being mechanically stressed.

These translucent profiles ensure that the channels provided for the LED arrangements are closed on four sides and thus protected from contamination. The channels only remain open on the two small lateral end faces so that the LED arrangements can be electrically connected.

The translucent profiles are placed between the carrier profile and the clamping profile in such a way that they can be easily removed, preferably after removing the clamping profile, and allow access to the LED arrangements. This is advantageous if maintenance or repair of an LED arrangement should become necessary.

A further development of the invention provides that the translucent profiles are made from polycarbonate. They can thus advantageously be extruded and thus allow cost-effective production with constant quality. Polycarbonate is a highly resilient material that is stable, lightweight and translucent at the same time.

According to a further development of the invention, the carrier profile and the clamping profile are made from extruded aluminum or an extruded aluminum alloy. Aluminum or aluminum alloys have proven to be advantageous since aluminum or aluminum alloys are largely corrosion-free and therefore have a long service life. In addition, the extrusion of aluminum or aluminum alloys is a proven and cost-effective manufacturing process.

A further development of the invention provides that the clamping profile is screwed to the carrier profile. This connection technique by means of screwing enables the clamping profile to be securely fastened to the carrier profile without the risk of unintentional loosening. It also enables screwing, exerting clamping forces on the plate elements so that there is no risk of the plate elements being displaced.

According to a further development of the invention, the profile arrangement also has a cover profile that covers the clamping profile. This allows a smooth surface to be provided without joints and the like that are prone to contamination.

A further development of the invention provides that the carrier profile and the clamping profile have mutually opposite grooves, for example T-slots, arranged in pairs in the areas in which the plate element or elements are clamped between the carrier profile and the clamping profile. The grooves are equipped with elastomer or rubber sealing profiles, which act in a clamping manner on this plate element between a plate element and the carrier profile on the one hand and between the plate element and the clamping profile on the other hand. A reliable clamping effect and sealing is thus achieved. This is advantageous in order to protect the LED arrangements from moisture and wetness.

According to a further development of the invention, the carrier profile has further grooves on the facade side, for example T-grooves, which are partly or entirely equipped with further elastomer or rubber profiles. These profiles provide a non-slip support on the outside of the building.

A further development of the invention provides that the carrier profile has a plurality of, for example, centrally arranged bores, which are equipped with wall anchors. The load of the facade system, in particular of the panel elements, is thus advantageously introduced into the outer wall of the building from the carrier profile.

According to a further development of the invention, the LED arrangements have housings made from extruded polycarbonate. This enables a transparent and at the same time stable and resilient enclosure of the LED arrangements.

A further development of the invention provides that the support profile has lateral round holes for fastening a lateral cover, so that the profile arrangements of the facade system are closed at their end faces by such lateral covers. This largely avoids openings for dirt and grime as well as moisture.

According to a further development of the invention, the plate element or elements are at least partially provided with photovoltaic elements. The energy supply for the LED arrangements can thus be obtained regeneratively and / or the electrical energy obtained can be fed into the public power grid. In this way, the electrical energy converted by the LED arrangements can be obtained by means of photovoltaics. The connection cables of the photovoltaic elements can advantageously be laid invisibly over the cable duct of the profile arrangement.

Further developments of the invention emerge from the claims, the description and the drawings. The aforementioned advantages of features and of combinations of several features are exemplary and can come into effect alternatively or cumulatively, without the advantages necessarily having to be achieved by embodiments according to the invention. Further features can be found in the drawings - in particular the geometries shown and the relative dimensions of several components to one another and their relative arrangement and operative connection. The combination of features of different configurations of the invention or of features of different claims is also possible in a way deviating from the selected back-references of the claims and is hereby proposed. This also applies to features that are shown in separate drawings or mentioned in their description. These features can also be combined with features of different claims. Features listed in the claims can also be omitted for further embodiments of the invention.
