Description

The present invention relates to a radio concrete installation housing for expanding a luminaire concrete installation housing and a system having a luminaire concrete installation housing and such a radio concrete installation housing.

In the construction of buildings, concrete is used, among other things, for ceilings (concrete ceilings), walls (concrete walls) and floors (concrete floors). In concrete construction, installation boxes (also called concrete installation boxes) can be provided, which are cast into a concrete ceiling and provide a cavity into which lights, in particular their electronic components, can be inserted after the building has been completed. Such installation boxes for accommodating lights, especially electronic components, can be referred to as concrete installation housings for lights. In principle, when constructing new buildings, it is possible to provide empty pipes in which lines can be arranged for wired communication between devices. The advantage of wired communication in concrete construction is that there is no shielding or attenuation of the communication signals transmitted via the wires. In contrast, with wireless communication, wireless communication signals, such as radio signals or radio waves, can be shielded or attenuated by concrete ceilings or concrete walls. Such shielding or attenuation may cause wireless communication to be impaired or even impossible in areas of a building that has concrete ceilings and optionally concrete walls.

However, wired communication between devices, such as different lights, is not always practical, so it is desirable to also be able to use radio modules for wireless communication using radio signals. For example, this can be advantageous if existing lights are to be retrofitted with a radio module for wireless communication. This can also be advantageous if a new concrete building is to be added to an existing building. In this case, wireless communication between devices (e.g. lights) in the existing building and devices (e.g. lights) in the new concrete building prevents concrete ceilings and optionally Concrete walls have to be slit open in order to lay empty conduits for cables for wired communication between the existing building and the new concrete building.

In light of the above statements, it is therefore an object of the present invention to create a possibility of being able to provide such radio modules in concrete construction. In particular, it is a task to create a way to enable wireless communication between devices in concrete construction, such as lights with radio modules.

These and other tasks that will be mentioned upon reading the following description or that can be recognized by a person skilled in the art are solved by the subject matter of the independent claims. The dependent claims further develop the central idea of the present invention in a particularly advantageous manner.

According to a first aspect of the present invention, a radio concrete installation housing is provided for expanding a luminaire concrete installation housing. The radio concrete installation housing has a decoupling surface for decoupling electromagnetic waves to the outside of the radio concrete installation housing. The radio concrete installation housing can be connected or connected to the luminaire concrete installation housing in such a way that a luminaire receiving opening of the luminaire concrete installation housing and the decoupling surface of the connected radio concrete installation housing are directed in the same direction.

That is, according to an alternative, the radio concrete installation housing is set up to be connected to the luminaire concrete installation housing in such a way (that is, the radio concrete installation housing can be connected to the luminaire concrete installation housing) in such a way that a luminaire receiving opening of the luminaire concrete installation housing and the decoupling surface of the radio -Concrete installation housing are directed in the same direction when the radio concrete installation housing is connected to the luminaire concrete installation housing. According to a further alternative, the radio concrete installation housing is connected to the luminaire concrete installation housing in such a way that a luminaire receiving opening of the luminaire concrete installation housing and the The decoupling surface of the radio concrete installation housing is directed in the same direction. According to the further alternative, the radio concrete installation housing can optionally be arranged in one piece directly on the luminaire concrete installation housing. Optionally, the radio concrete installation housing can be designed in one piece with the luminaire concrete installation housing. If the radio concrete installation housing is connected to the luminaire concrete installation housing, then the radio concrete installation housing can include the radio concrete installation housing as such and the luminaire concrete installation housing.

In other words, the first aspect of the present invention proposes to provide a radio concrete installation housing for expanding a luminaire concrete installation housing, the radio concrete installation housing being optimized for coupling out electromagnetic waves (for example radio waves). The radio concrete installation housing is optimized for the decoupling of electromagnetic waves due to its decoupling surface.

The radio concrete installation housing therefore allows wireless communication using electromagnetic waves (e.g. radio waves) between lights in concrete construction. Because if the radio concrete installation housing is installed or cast together with a luminaire concrete installation housing in concrete, for example in a concrete ceiling, then the luminaire that can be arranged in the luminaire concrete installation housing via the luminaire receiving opening can be positioned outside of the concrete via the radio concrete installation housing ( e.g. concrete ceiling) emit electromagnetic waves (e.g. radio waves) into the open space (e.g. an interior of the concrete building) for wireless communication. Here, the radio concrete installation housing, in particular its decoupling surface, enables the electromagnetic waves to be decoupled in the direction of light emission from the luminaire that can be arranged in the luminaire concrete installation housing. The electromagnetic waves can thus be decoupled from the concrete in an optimized manner, since the electromagnetic waves are not decoupled in the direction of the concrete or without a specific direction via the decoupling surface of the radio concrete installation housing. As a result, shielding or damping of the coupled-out electromagnetic waves by the concrete can be reduced in such a way that this shielding or damping is negligible for wireless communication. That is, the shielding or Attenuation is so low that wireless communication using electromagnetic waves (e.g. radio waves) is possible.

Thus, the radio concrete installation housing according to the first aspect of the present invention is advantageous because it enables wireless communication by means of electromagnetic waves (e.g. radio waves) between lights arranged in luminaire concrete installation housings.

The radio concrete installation housing can be detachably connected or connected to the luminaire concrete installation housing.

The passage that "the radio concrete installation housing can be connected to the luminaire concrete installation housing in such a way that a luminaire receiving opening of the luminaire concrete installation housing and the decoupling surface of the connected radio concrete installation housing are directed in the same direction" means that "the radio concrete installation housing is set up or designed to be connected to the luminaire concrete installation housing in such a way that a luminaire receiving opening of the luminaire concrete installation housing and the decoupling surface of the connected radio concrete installation housing are directed in the same direction.

The decoupling surface is set up or designed for decoupling or radiating electromagnetic waves (e.g. radio waves). For example, the decoupling surface is set up or designed for decoupling or radiating electromagnetic waves (e.g. radio waves) from inside the radio concrete installation housing to outside the radio concrete installation housing.

A concrete installation housing is a housing that is designed for installation in concrete, ie in a concrete layer. This means that the concrete installation housing is designed to be surrounded by concrete from one or more sides, optionally from all sides (apart from the lamp receiving opening in the case of a lamp concrete installation housing), with the amount of concrete being at various points on the outside (ie external surfaces ) of the concrete installation housing can vary.

The luminaire concrete installation housing can be abbreviated by the term "luminaire installation housing" and the radio concrete installation housing can be abbreviated by the term "radio installation housing". The radio concrete installation housing can represent a radio concrete installation channel or a radio concrete installation box or can be referred to as such. Accordingly, the luminaire concrete installation housing can represent a luminaire concrete installation channel or luminaire concrete installation box or can be referred to as such.

The wireless concrete installation housing has a cavity. The radio concrete installation housing can be cuboid or cylindrical. The decoupling surface of the radio concrete installation housing can in particular be the surface of the radio concrete installation housing with the largest longitudinal extent.

The electromagnetic waves that can be coupled out via the decoupling surface of the radio concrete installation housing can be radio waves. Radio waves can also be called radio waves. The radio waves can, for example, be electromagnetic waves in a range between 1GHz and 25 GHz, optionally in a range between 2 GHz and 5 GHz.

The direction of the lamp receiving opening of the lamp concrete installation housing corresponds to the direction of light emission from a lamp when it is at least partially arranged via the lamp receiving opening in a cavity of the lamp concrete installation housing.

The radio concrete installation housing can be set up to couple electromagnetic waves into a cavity of the radio concrete installation housing starting from the luminaire concrete installation housing and to couple out the coupled electromagnetic waves via the decoupling surface to the outside of the radio concrete installation housing when the radio concrete installation housing is connected to the luminaire. Concrete installation housing is connected.

In other words, in the connected state, the radio concrete installation housing can be set up to transmit electromagnetic waves from the luminaire concrete installation housing into a cavity of the radio concrete installation housing and to decouple the coupled electromagnetic waves via the decoupling surface to the outside of the radio concrete installation housing.

Thus, the radio concrete installation housing can be optimized for coupling in electromagnetic waves (for example radio waves) from the direction of the luminaire concrete installation housing and for coupling out electromagnetic waves in the direction of the coupling surface.

Optionally, the radio concrete installation housing is set up to at least partially accommodate an antenna, a radio module or a lamp operating device having a radio module in such a way that electromagnetic waves emitted by the antenna, the radio module or the lamp operating device can be coupled out via the decoupling surface to the outside of the radio concrete installation housing , and the antenna, the radio module or the lamp operating device can be electrically connected to an interior of the luminaire concrete installation housing when the radio concrete installation housing is connected to the luminaire concrete installation housing.

In other words, the radio concrete installation housing can accommodate or partially accommodate components for wireless communication, such as an antenna, a radio module and/or a lamp operating device having a radio module, in such a way that electromagnetic waves emitted by such accommodated or partially accommodated components (for Example radio waves) can be coupled out via the decoupling surface of the radio concrete installation housing to outside the radio concrete installation housing. The electromagnetic waves emitted by such components can therefore be emitted via the decoupling surface to the outside of the radio concrete installation housing, in particular in the direction of the normal vector of the decoupling surface. This enables wireless communication of such components with other components or devices arranged outside the radio concrete installation housing. The above-mentioned components can be arranged or partially arranged in the cavity of the radio concrete installation housing.

At the same time, the above-mentioned components can be at least partially accommodated by the radio concrete installation housing in such a way that these components, in the recorded state, with an interior of the luminaire concrete installation housing can be electrically connected if the radio concrete installation housing is connected to the luminaire concrete installation housing. This makes it possible to equip or expand a luminaire or removable electronic components (optionally components of a luminaire, such as a control and/or operating device for lamps) that can be accommodated by the luminaire concrete installation housing in the recorded state via the above-mentioned components for wireless communication when the radio concrete installation housing is connected to the luminaire concrete installation housing.

The radio module can also be referred to as a communication module for wireless communication.

Optionally, the radio concrete installation housing is made of a material that is permeable to electromagnetic waves. The material that is permeable to electromagnetic waves can be plastic. In other words, the radio concrete installation housing can be a plastic housing, such as a plastic injection molded housing. A material that is permeable to electromagnetic waves can optionally mean a material that is permeable to radio waves.

Optionally, the radio concrete installation housing is made of a material that is permeable to electromagnetic waves and an inside of the radio concrete installation housing has a metallic coating outside the coupling surface. For example, the material permeable to electromagnetic waves can be plastic.

In other words, for example, the radio concrete installation housing can be a plastic housing, such as a plastic injection molded housing, the inside of which is provided with a metallic coating that is interrupted, i.e. not present, in the area of the coupling surface

The metallic coating can support, for example amplify, the radiation or decoupling of electromagnetic waves from within the radio concrete installation housing via the decoupling surface to the outside of the radio concrete installation housing. This radiation can be due to the metallic Coating can be done in a certain direction, for example reinforced in a certain direction. This direction can be in the direction of the normal vector of the decoupling surface outside the radio concrete installation housing. The above can be done, among other things, by reflection of the electromagnetic wave on the metallic coating. The metallic coating can increase the proportion of electromagnetic waves (such as radio waves) emitted within the radio concrete installation housing and/or coupled into the radio concrete installation housing, which is coupled out via the coupling surface, and thus the coupling of the electromagnetic waves to the outside of the radio -Optimize concrete installation housing. The metallic coating leads to reflections of the electromagnetic waves on the coating, which reduces absorption losses within the radio concrete installation housing and consequently more power or energy can be extracted via the decoupling surface. Consequently, the signal strength of radio signals within the radio concrete installation housing is reduced less and radio signals with a higher signal strength compared to a radio installation housing without a metallic coating can be coupled out via the decoupling surface.

Due to the metallic coating, the radio concrete installation housing can be designed as a waveguide or have the function of a waveguide. The term “hollow chamber conductor for electromagnetic waves (e.g. radio waves)” can be used synonymously for the term “waveguide”.

Optionally, the radio concrete installation housing outside the coupling surface is a metal housing, and the coupling surface is made of a material that is permeable to electromagnetic waves, at least in a partial area. For example, the material permeable to electromagnetic waves can be plastic.

The above with regard to the optional feature of the metallic coating applies accordingly to the optional case that the radio concrete installation housing outside the decoupling surface is a metal housing. Due to the metal housing, the radio concrete installation housing can be designed as a waveguide or have the function of a waveguide.

Optionally, a slot-shaped opening is arranged in the decoupling surface and the slot-shaped opening is designed as a slot antenna.

This supports, for example increased, the coupling out of the electromagnetic waves via the coupling surface or the radiation of electromagnetic waves from the coupling surface to the outside of the radio concrete installation housing. Due to the slot-shaped opening designed as a slot antenna, this radiation can take place in a specific direction, for example, it can be amplified in a specific direction. This direction can be in the direction of the normal vector of the decoupling surface outside the radio concrete installation housing. The slot-shaped opening designed as a slot antenna leads to an excitation and thus amplification of radiation of electromagnetic waves from inside the radio concrete installation housing to outside the radio concrete installation housing.

The coupling-out surface can have an opening or correspond to an opening, the opening being designed or set up for coupling out electromagnetic waves (for example radio waves). In particular, the shape of the opening for coupling out the electromagnetic waves can be adapted or optimized.

The slot antenna can be part of a radio module that can be arranged or arranged at least partially in the radio concrete installation housing or a lamp operating device having a radio module or can be arranged as a dedicated antenna in the radio concrete installation housing, wherein the radio concrete installation housing is optionally designed as a waveguide or represents a waveguide.

Optionally, the radio concrete installation housing is a waveguide.

In other words, the radio concrete installation housing can be designed in such a way that it has the function of a waveguide. As a result, electromagnetic waves (such as radio waves) emitted within the radio concrete installation housing and/or coupled into the radio concrete installation housing can be guided within the radio concrete installation housing in the direction of the decoupling surface and consequently be decoupled via the decoupling surface. This improves the decoupling of electromagnetic waves via the decoupling surface.

The longitudinal extent of the radio concrete installation housing can be the longitudinal extent of the decoupling surface, and the longitudinal extent of the radio concrete installation housing can be unequal to a multiple of a quarter of the wavelength of the electromagnetic waves to be decoupled.

This prevents the occurrence of standing, negatively superimposed waves within the radio concrete installation housing, whereby the occurrence of standing waves with negative interference would be detrimental to the decoupling of the electromagnetic waves via the decoupling surface. In other words, this prevents a wave of the radio concrete installation housing reflected at the end of the longitudinal extension from leading to the extinction of electromagnetic waves to be coupled out via the decoupling surface. This optional feature can therefore support and thus improve the decoupling of electromagnetic waves via the decoupling surface.

The longitudinal extent of the radio concrete installation housing can be larger or longer than the longitudinal extent of the decoupling surface.

The longitudinal extent of the radio concrete installation housing can be the longitudinal extent of the decoupling surface, and on the outside of the radio concrete installation housing there can be markings along the longitudinal extent of the radio concrete installation housing, which indicate a longitudinal extent of multiples of a quarter of the wavelength of the electromagnetic waves to be decoupled.

The markings can be arranged on the outside of the radio concrete installation housing on a surface of the radio concrete installation housing opposite the decoupling surface, the surface having the same longitudinal extent as the decoupling surface. The area can have the same dimensions as the output area.

The marking makes it possible when using the wireless concrete installation housing (e.g. positioning in a formwork for pouring concrete to produce a Concrete component (e.g. a concrete ceiling) a cut of the radio concrete installation housing to any length, ensuring that a length that is disadvantageous for the decoupling of electromagnetic waves via the decoupling surface of the radio concrete installation housing is avoided. For this purpose, the user may not cut the radio concrete installation housing at the markings but only between them. In particular, the user may not cut the wireless concrete installation housing at the markings or in a tolerance area around the markings. This ensures that the longitudinal extent of the tailored radio concrete installation housing is not a multiple of a quarter of the wavelength of the electromagnetic waves to be decoupled, which, as described above, can be disadvantageous for the decoupling of electromagnetic waves.

Optionally, the radio concrete installation housing for connection to the luminaire concrete installation housing is set up to be flanged to the luminaire concrete installation housing or to be brought into engagement with the luminaire concrete installation housing. Optionally, the radio concrete installation housing is connected to the luminaire concrete installation housing in that the radio concrete installation housing is flanged to the luminaire concrete installation housing or is brought into engagement with the luminaire concrete installation housing.

The radio concrete installation housing can be connected or connectable to the luminaire concrete installation housing in a force-fitting, form-fitting and/or material-locking manner. The radio concrete installation housing can be mechanically connected or connectable to the luminaire concrete installation housing. For example, at least one connecting element of the radio concrete installation housing can engage, snap, slide in and/or be connected in some other way with a corresponding connecting element of the luminaire concrete installation housing.

The radio concrete installation housing can have a coupling surface or an opening from outside to a cavity of the radio concrete installation housing at one end of the longitudinal extent of the radio concrete installation housing, and the radio concrete installation housing can be connectable or connected to the luminaire concrete installation housing in such a way that starting from Electromagnetic waves can be coupled into the luminaire concrete installation housing via the coupling surface or the opening into the cavity of the connected radio concrete installation housing.

The coupling surface or opening of the radio concrete installation housing is set up or designed for coupling in electromagnetic waves (e.g. radio waves) from outside the radio concrete installation housing to inside the radio concrete installation housing, i.e. into the cavity of the radio installation housing. The abbreviation "or." stands for “respectively”. The term “or” can be used instead of the abbreviation “or.” be used.

In the event that an inside of the radio concrete installation housing outside the coupling surface has a metallic coating or the radio concrete installation housing outside the coupling surface is a metal housing, the coupling surface can be made of a material that is permeable to electromagnetic waves (for example radio waves), at least in a partial area. for example plastic.

In other words, according to an alternative, the radio concrete installation housing can have a coupling surface at one end of the longitudinal extent of the radio concrete installation housing, and the radio concrete installation housing can be connectable or connected to the luminaire concrete installation housing in such a way that starting from the luminaire concrete installation housing electromagnetic Waves can be coupled into a cavity of the connected radio concrete installation housing via the coupling surface. The radio concrete installation housing can be connected or connectable to the luminaire concrete installation housing at the end of the longitudinal extent at which the coupling surface is present.

According to a further alternative, the radio concrete installation housing can have an opening from the outside to a cavity of the radio concrete installation housing at one end of the longitudinal extent of the radio concrete installation housing, and the radio concrete installation housing can be connectable or connected to the luminaire concrete installation housing in such a way that starting from Electromagnetic waves can be coupled from the luminaire concrete installation housing via the opening into the cavity of the connected radio concrete installation housing. The radio concrete installation housing can be connected or connectable to the luminaire concrete installation housing at the end of the longitudinal extent at which the opening is present.

Optionally, the radio concrete installation housing has the opening from the outside to the cavity of the radio concrete installation housing at the end of the longitudinal extent of the radio concrete installation housing if the radio concrete installation housing is to be coupled to an adjacent housing, i.e. is to be connected to it. This adjacent housing can either be a concrete luminaire installation housing or a special housing that is intended to accommodate electronic components, for example for a system consisting of a luminaire installation housing and a radio concrete installation housing. The radio concrete installation housing can be coupled or connected to the luminaire installation housing via a further housing, for example the special housing mentioned above. For example, the electrical components of the lamp can be arranged in the luminaire installation housing and electrical components for wireless communication can be arranged in the further housing. Electromagnetic waves emitted by the electronic component for wireless communication, such as radio waves, can then be coupled into the radio concrete installation housing from the further housing in order to then be emitted via the decoupling surface of the radio concrete installation housing to the outside of the radio concrete installation housing ( for example in a room if the light installation housing, the other housing and the radio installation housing are installed in the concrete ceiling of the room). The further housing can also be referred to as a further concrete installation housing or another installation housing.

The opening of the radio concrete installation housing can be designed such that at least one electrical component of an adjacent housing (for example the light installation housing or the other housing described above), with which the radio concrete installation housing is connectable or connected, at least partially via the opening of the radio concrete installation housing is arranged in the radio concrete installation housing when the radio concrete installation housing is connected to the adjacent housing. The at least one electrical component can be a radio module having an antenna, a radio module and/or a lamp operating device.

The opening or the coupling surface of the radio concrete installation housing can have a dimension in a range greater than or equal to half a wavelength and smaller equal to a wavelength of the electromagnetic waves to be coupled in.

In other words, the dimension of the opening or the coupling surface can be coordinated with the wavelength of the electromagnetic waves to be coupled in (for example radio waves). This improves the coupling properties of the opening or coupling surface with regard to the coupling of the electromagnetic waves. For example, if the electromagnetic waves have a frequency of 2.4 GHz and optionally in the range of 2.4 GHz, then an opening or coupling surface dimension of half a wavelength that is advantageous for this frequency would be approximately equal to 6.2 cm.

Optionally, the radio concrete installation housing has an absorber for suppressing reflections of electromagnetic waves at an end of the longitudinal extent of the radio concrete installation housing in the cavity opposite the coupling surface or the opening.

The “absorber” can also be referred to as a “damper”. The absorber can be made of an absorption material for the electromagnetic waves (for example radio waves). The absorber can be set up to absorb (swallow) or dampen electromagnetic waves at the end of the longitudinal extent of the radio concrete installation housing (and thus the longitudinal extent of the decoupling surface) opposite the coupling surface or the opening. As a result, the electromagnetic waves can be absorbed or dampened at this end of the longitudinal extension instead of being reflected. This prevents a wave of the radio concrete installation housing reflected at the end of the longitudinal extension from leading to the extinction of electromagnetic waves to be coupled out via the decoupling surface. Consequently, the absorber supports or improves an outcoupling of electromagnetic waves via the outcoupling surface to the outside of the radio concrete installation housing.

Optionally, the radio concrete installation housing has a decoupling unit on the outside of the decoupling surface for decoupling the electromagnetic waves.

The material, the geometric shape and/or dimensions of the decoupling unit can be designed in such a way that the decoupling unit supports, for example enhances, a decoupling or radiation of electromagnetic waves from inside to outside of the radio concrete installation housing. The material, the geometric shape and/or dimensioning of the decoupling unit can be designed such that the decoupling unit guides the waves to be decoupled out in a specific direction, for example in the direction of the normal vector of the decoupling surface, outside the radio concrete installation housing and consequently decouples them.

The decoupling unit is at least partially made of a material that is permeable to the electromagnetic waves, such as plastic. The decoupling unit can have metal or a metal coating in such a way that the decoupling unit has the function of a waveguide.

The wireless concrete installation housing optionally has one or more spacers on the outside.

The following description is aimed at several spacers and applies accordingly in the case that the wireless concrete installation housing has a spacer on the outside.

The spacers can be provided on the outside outside of the decoupling surface. The spacers can be provided laterally along the longitudinal extent of the wireless concrete installation housing. For example, when using the wireless concrete installation housing in concrete construction, these spacers can ensure that when the wireless concrete installation housing is inserted into a formwork for pouring concrete, a minimum distance is guaranteed between the wireless concrete installation housing and a steel reinforcement commonly used when pouring concrete. This enables a minimum distance between the wireless concrete installation housing and metallic components when the wireless concrete installation housing is cast in a concrete component, for example a concrete ceiling. In other words, the lateral provision of spacers can ensure a desired relative position of the wireless concrete installation housing to the steel reinforcement (for example the individual bars of steel mats of a concrete ceiling).

This is advantageous because when the wireless concrete installation housing is arranged close to metallic components (such as the steel reinforcement), i.e. below a minimum distance from them, the metallic components can have the effect of a Faraday cage for the wireless concrete installation housing. This is disadvantageous for coupling or radiation of electromagnetic waves from inside the radio concrete installation housing to the outside when the radio concrete installation housing is installed in the concrete.

Steel reinforcement can also be referred to as metal reinforcement, metallic reinforcement or steel reinforcement.

The spacers described above can protrude perpendicularly (i.e. in the direction of the normal vector of the respective surface) from the outside of surfaces of the radio concrete installation housing that are arranged laterally to the decoupling surface. These laterally arranged surfaces can be perpendicular to the decoupling surface, as is the case, for example, with a cuboid radio concrete installation housing.

The spacers described above can protrude from the outside of the radio concrete installation housing (optionally outside the decoupling surface) in such a way that the longitudinal axis of the respective spacer of these spacers forms an angle of 90 °, optionally essentially 90 °, with the normal vector of the decoupling surface. This can be the case, for example, with a cylindrical shape of the wireless concrete installation housing. If the wireless concrete installation housing has a cylindrical shape, the coupling surface can be part of the lateral surface of the cylinder. Optionally, the cylindrical shape of the radio concrete installation housing on the coupling surface can be planar or essentially planar.

The spacers described above for maintaining a minimum distance from metallic components can be referred to as first spacers.

The one or more spacers may be configured to be connected to steel reinforcement.

In other words, the one or more first spacers can be connected to the steel reinforcement. This connection can be a positive, non-positive and/or cohesive connection. The one or more first spacers can be mechanically connected to the steel reinforcement. For example, the one or more first spacers may be engaged with the steel reinforcement.

This allows the wireless concrete installation housing to be positioned and oriented in a formwork for pouring concrete using the steel reinforcement used for concreting, i.e. aligned, and then fixed in the selected position and orientation. This ensures or reduces the risk that the selected or desired position and orientation of the radio installation housing is changed when the concrete is poured into the formwork.

In other words, using such lateral spacers or fixings, the wireless concrete installation housing can be attached to the steel mats (i.e. steel reinforcement) to be provided in, for example, a concrete ceiling. When the concrete ceiling is subsequently cast, this ensures that the installation housing is not displaced into an area in which the steel of the steel mats hinders wireless transmission of electromagnetic waves, such as radio waves.

Additionally or alternatively, the radio concrete installation housing can have one or more spacers on the outside, which are attached to the side of the coupling surface. This one or more spacers may be referred to as second spacers. The following description is directed to several second spacers and applies accordingly to the case that the wireless concrete installation housing has a second spacer on the outside.

Optionally, the second spacers can be provided on the outside of the radio installation housing on the side of the decoupling surface in such a way that they protrude from the outside of the radio installation housing in the direction of the normal vector of the decoupling surface. The second spacers can be provided on the outside in the area of the decoupling surface in such a way that they point in the direction of Normal vector of the decoupling surface protruding from the decoupling surface or the decoupling unit.

The second spacers can have a length between 0.5 cm and 2 cm, optionally a length of 2 cm. This can enable an advantageous layer thickness corresponding to the length of the spacers for the concrete covering the decoupling surface and optionally the decoupling surface when the radio installation housing is positioned in the formwork for pouring concrete. When pouring a concrete ceiling, the radio installation housing must be positioned in such a way that the decoupling surface is positioned towards the underside of the formwork, i.e. towards the space for which the concrete ceiling is being cast.

The function of wireless communication using electromagnetic waves, such as radio communication, can be sensitive to the achievable signal strength of the wireless signals. Measures must therefore be provided which enable good coupling of the electromagnetic waves or wireless signals (for example radio waves or radio signals) from the radio concrete installation housing into a room when the radio concrete installation housing is cast in the concrete ceiling of the room. The covering of concrete towards the room on the side on which wireless signals (e.g. radio signals) are decoupled from the radio installation housing, i.e. the covering of the decoupling surface of the radio installation housing with concrete, has an influence on the signal strength of the wireless signals ( radio signals). A thickness of between 0.5 cm and 2 cm of the covering concrete enables a signal strength of radio signals that is advantageous for wireless communication, after the radio signals are coupled out via the decoupling surface of the radio concrete installation housing to the outside of the radio installation housing and then through the concrete covering the decoupling surface radiated into the room. Experiments have shown that at the wavelength currently used, coverage in the range of approximately 2 cm is better than coverage in the range of approximately 1 cm.

Consequently, the second spacers of the radio concrete installation housing are advantageous for the above reasons.

The first spacers and/or the second spacers can be made of a material that is permeable to electromagnetic waves (e.g. radio waves), such as plastic.

Optionally, the radio concrete installation housing has one or more elongated height indicators on the outside of a surface of the radio concrete installation housing opposite the coupling surface to display the height of a concrete layer that can be applied to the outside of the surface, the one or more elongated height indicators pointing in the direction of the normal vector of the stand out from the surface. The one or more elongated height indicators may be one or more height indicator rods.

The following description is aimed at several height displays and applies accordingly in the event that the wireless concrete installation housing has a height display on the outside.

The elongated height indicators make it possible, when pouring concrete over the radio concrete installation housing arranged in a formwork for pouring concrete, to immediately see how large the coverage is on the outside of the surface of the radio concrete installation housing of the radio concrete installation housing opposite the decoupling surface. The term "altitude indicator" can be used synonymously with the term "altitude indicator".

Furthermore, the height indicators enable the position of the radio concrete installation housing in the concrete to remain visible after the concrete has been poured into a formwork in which the radio concrete installation housing can be arranged. Consequently, when processing the concrete using a vibrator, care can be taken in the area of the wireless concrete installation housing in order to avoid a disadvantageous displacement of the wireless installation housing in the concrete. At the same time, sufficient shaking can also occur so that the concrete mass flows evenly (ie cleanly) under the underside, ie the side of the decoupling surface of the radio concrete installation housing. For this advantage it is sufficient that the respective height indicator is a simple rod without markings.

The height indicators can have height markings (for example in 5 cm and or 1cm cm increments) so that a concrete application height can be adjusted and these height markings can serve as a leveling aid when removing.

In order to achieve the radio concrete installation housing according to the invention, the above optional features and embodiments can be combined with one another as desired.

According to a second aspect of the present invention, a system is provided. The system has a luminaire concrete installation housing for accommodating lighting devices and a radio concrete installation housing according to the first aspect of the present invention, as described above. The lamps are optionally at least one light-emitting diode.

The luminaire concrete installation housing can accommodate lamps and other components, for example electrical components and optionally optical components, of a luminaire via a luminaire receiving opening. The luminaire concrete installation housing can accommodate or at least partially accommodate the luminaire via the luminaire receiving opening.

The luminaire concrete installation housing can accommodate a radio module having an antenna, a radio module and/or a lamp operating device via the luminaire receiving opening. The luminaire concrete installation housing can have an opening or a decoupling surface for electromagnetic waves (for example radio waves) on the side on which the radio concrete installation housing can be connected or connected to the luminaire concrete installation housing. Consequently, the electromagnetic waves can be coupled into the radio installation housing via the opening or decoupling surface of the luminaire installation housing when the radio installation housing is connected to the luminaire installation housing.

Figures 1 to 3 each show a schematic longitudinal view of an example of a preferred embodiment of a radio concrete installation housing according to the invention.

The above description of the wireless concrete installation housing according to the first aspect of the present invention is for the wireless concrete installation housing Figures 1 to 3 appropriately applicable.

The radio concrete installation housing 1 of the Figure 1 is a radio concrete installation housing for expanding a luminaire concrete installation housing 2. The radio concrete installation housing 1 has a decoupling surface 1b for coupling out electromagnetic waves to the outside of the radio concrete installation housing 1. As in Figure 1 indicated by the arrow between the radio installation housing 1 and the light installation housing 2, the radio concrete installation housing 1 can be connected to the light concrete installation housing 2. In particular, the radio concrete installation housing 1 can be connected to the luminaire concrete installation housing in such a way that a lamp receiving opening of the luminaire concrete installation housing 2 and the decoupling surface 1b of the connected radio concrete installation housing 1 are directed in the same direction. In Figure 1 This direction is indicated by the arrow below the luminaire concrete installation housing 2. This in Figure 1 The radio installation housing 1 shown can be detachably connected to the light installation housing.

For example, the radio concrete installation housing 1 for connection to the luminaire concrete installation housing 2 can be set up to be flanged to the luminaire concrete installation housing 2 or to be brought into engagement with the luminaire concrete installation housing 2.

Figure 2 shows the connected state of the radio concrete installation housing 1, ie the state when the radio concrete installation housing 1 is connected to the lamp concrete installation housing 2 in such a way that the lamp receiving opening of the lamp concrete installation housing 2 and the decoupling surface 1b of the connected radio concrete installation housing 1 in the are directed in the same direction.

This in Figure 2 The radio concrete installation housing 1 shown can be arranged in one piece directly on the luminaire concrete installation housing 2. Optionally, the radio concrete installation housing 1 can be made in one piece with the luminaire concrete installation housing 2 be trained. The description of the in Figure 1 Components shown, in particular the radio installation housing 1 and the light installation housing 2, are for the in Figure 2 Components shown, in particular the radio installation housing 1 and the light installation housing 2 of the Figure 2 , also applicable.

Like in the Figures 1 and 2 shown, the luminaire installation housing can accommodate 2 components of a luminaire via the luminaire receiving opening. For example, the luminaire installation housing can accommodate or at least partially accommodate illuminants 23, such as at least one light-emitting diode (LED) or a light-emitting diode module (LED module) with at least one LED. Additionally or alternatively, the lamps can have at least one other known type of lamp. Furthermore, the lamp installation housing 2 can accommodate an electrical circuit 21 of the lamp for the electrical supply and/or control of electrical components of the lamp, such as the lamps 23, via the lamp receiving opening. The electrical circuit 21 can, for example, have a lamp operating device (for example an LED operating device) and optionally a control module for electrically supplying the electrical components of the lamp (for example the lamps 23) and controlling these electrical components (for example a light output from the lamps 23).

The lamps 23 can be arranged in the lamp installation housing 2 in such a way that light is emitted from the lamps 23 through the lamp receiving opening to the outside of the lamp installation housing 2. The luminaire installation housing 2 can optionally accommodate the luminaire in such a way that, in the recorded state, the lamps 23 of the luminaire are arranged partially outside the luminaire installation housing 2 in the area of the luminaire receiving opening in order to enable light to be emitted to the outside of the luminaire installation housing 2.

The luminaire installation housing 2 can also accommodate or at least partially accommodate optical components 24 of the luminaire (eg optics comprising one or more lenses, one or more reflectors, etc.) via the luminaire receiving opening. Like in the Figures 1 and 2 shown, for example, reflectors 24 (eg metallic reflectors) can be arranged partially in the luminaire installation housing 2 and through the luminaire receiving opening to the outside of the luminaire installation housing 2 protrude in order to direct the light output of the lamps 23 in a certain direction.

As in Figures 1 and 2 indicated, a radio module 22 can also be arranged in the lamp installation housing 2 as a component of the lamp or as a component electrically connected to the lamp. Through this radio module 22, wireless communication of the light that can be arranged in the light installation housing 2 with other devices, for example other lights, can be possible or the light can be expanded using this function. The radio module 22 can be electrically connected to the electrical circuit 21, for example the operating device and/or the optional control module, of the lamp, or can be a component of this, for example the operating device or the optional control module.

As in Figures 1 and 2 shown, the radio module 22 or an antenna used for wireless communication (in Figures 1 and 2 not shown) can be arranged in the luminaire installation housing 2 in such a way that the electromagnetic waves, in particular radio waves, emitted by the radio module 22 or the antenna are coupled out of the luminaire installation housing 2 in the direction of one side of the luminaire installation housing 2, on which the radio installation housing 1 can be connected or is connected to the light installation housing. For this purpose, the light installation housing 2 can have an opening (as in Figures 1 and 2 shown) or have a decoupling surface. The antenna can be electrically connected to the radio module 22 or be a component of the radio module 22.

The radio concrete installation housing 1 is set up to couple electromagnetic waves emitted from the luminaire concrete installation housing 2, such as radio waves, into a cavity 1c of the radio concrete installation housing 1, ie into the radio concrete installation housing, and the coupled electromagnetic waves via the decoupling surface 1b to be decoupled outside the radio concrete installation housing 1 when the radio concrete installation housing 1 is connected to the luminaire concrete installation housing 2. For this purpose, the radio concrete installation housing 1 can have a coupling surface (in Figures 1 or 2 not shown) or an opening 11 (in Figures 1 and 2 shown) from outside to the cavity 1c of the radio concrete installation housing 1 have, and the radio concrete installation housing 1 can be connected or connected to the luminaire concrete installation housing 2 in such a way that, starting from the luminaire concrete installation housing 2, electromagnetic waves can be coupled into the cavity 1c of the connected radio concrete installation housing 1 via the coupling surface or the opening 11 are. Consequently, the above-mentioned end of the longitudinal extension LE of the radio installation housing 1 corresponds to the end or the side of the radio installation housing 1 on which the radio installation housing 1 can be connected or is connected to the luminaire installation housing.

The opening 11 or the coupling surface of the radio concrete installation housing 1 can have a dimension in a range greater than or equal to half a wavelength and less than or equal to a wavelength of the electromagnetic waves to be coupled in (e.g. radio waves). This can apply accordingly to the opening or decoupling surface of the luminaire installation housing 2 for decoupling electromagnetic waves, such as radio waves.

Optionally, the radio concrete installation housing 1 can be set up to at least partially accommodate an antenna, a radio module 22 or a lamp operating device having a radio module in such a way that electromagnetic waves emitted by the antenna, the radio module 22 or the lamp operating device are transmitted via the decoupling surface 1b to the outside of the radio -Concrete installation housing 1 can be decoupled, and the antenna, the radio module 22 or the lamp operating device can be electrically connected to an interior of the luminaire concrete installation housing 2, for example the electrical circuit 21 that can be arranged inside, if the radio concrete installation housing 1 is connected to the luminaire concrete installation housing 2 is connected.

In Figure 1 The case is indicated, for example, by a dashed block 22, in which a radio module 22 for wireless communication of the lamp that can be arranged in the luminaire installation housing 2 is arranged within the radio installation housing 1, ie in the cavity 1c of the radio installation housing 1.

The radio concrete installation housing 1 can be designed as described above with regard to the radio installation housing of the first aspect of the invention. For example, the radio concrete installation housing can be made of a material (e.g. plastic) that is permeable to electromagnetic waves (e.g. radio waves) and an inside of the radio concrete installation housing 1, ie the inside of the cavity 1c, outside the coupling surface 1b can have a metallic coating (in Figures 1 and 2 Not shown).

Alternatively, the radio concrete installation housing 1 can be a metal housing outside the decoupling surface 1b, and the decoupling surface 1b can be made of a material (e.g. plastic) that is permeable to electromagnetic waves (e.g. radio waves), at least in a partial area.

Optionally, a slot-shaped opening is arranged in the decoupling surface 1b and the slot-shaped opening is designed as a slot antenna (in Figures 1 and 2 not shown).The radio concrete installation housing 2 can be a waveguide or have the function of a waveguide.

The above-described design of the radio installation housing 1, in particular the cavity 1c, makes it possible to guide electromagnetic waves, for example radio waves, within the radio installation housing 1 (i.e. in the cavity 1c) in such a way that these waves pass over the decoupling surface with low losses 1b are coupled out to the outside of the radio installation housing 1 and thus radiated. Here, the decoupling can take place in the direction of the normal vector N2 of the decoupling surface 1b.

The longitudinal extent LE of the radio concrete installation housing 1 can be the longitudinal extent of the decoupling surface 1b, and the longitudinal extent of the radio concrete installation housing 1 can be unequal to a multiple of a quarter of the wavelength of the electromagnetic waves to be decoupled. As in Figures 1 and 2 shown, markings 13 can optionally be present on the outside of the radio concrete installation housing 2 along the longitudinal extent LE of the radio concrete installation housing 1, which indicate a longitudinal extent of multiples of a quarter of the wavelength of the electromagnetic waves to be coupled out. This enables an advantageous cutting of the radio concrete installation housing in the longitudinal extent or longitudinal direction.

Optionally, the radio concrete installation housing 2 has an end of the longitudinal extension LE of the radio concrete installation housing opposite the coupling surface or the opening 11 1 in the cavity 1c an absorber 12 for suppressing reflections of electromagnetic waves.

Optionally, the radio concrete installation housing has one or more spacers 15, 16 on the outside.

For example, the radio installation housing can have one or more spacers 16 on the outside outside the coupling surface. These spacers 16 can be referred to as first spacers. The ones in the Figures 1 and 2 The number of first spacers 16 shown is merely exemplary and not restrictive. The first spacers can 16 be provided laterally along the longitudinal extent LE of the radio concrete installation housing 1. For example, when using the wireless concrete installation housing 1 in concrete construction, the first spacers 16 can ensure that when the wireless concrete installation housing is inserted into a formwork for pouring concrete, a minimum distance is guaranteed between the wireless concrete installation housing 1 and a steel reinforcement commonly used in concrete pouring .

The one or more first spacers may be configured to be connected to steel reinforcement.

Additionally or alternatively, the radio concrete installation housing 1 can have one or more spacers 15 on the outside, which can be attached to the side of the decoupling surface 1b. This one or more spacers 15 can be referred to as second spacers. The ones in the Figures 1 and 2 The number of second spacers 15 shown is merely exemplary and not restrictive. The second spacers 15 can be provided on the outside in the area of the coupling-out surface 1b in such a way that they protrude from the coupling-out surface 1b in the direction of the normal vector N2 of the coupling-out surface 1b. The second spacers 15 can have a length between 0.5 cm and 2 cm, optionally a length of 2 cm. This can enable an advantageous layer thickness corresponding to the length of the spacers for the concrete covering the coupling surface when the radio installation housing is positioned in the formwork for pouring concrete.

Optionally, the radio concrete installation housing 1 can have one or more elongated height indicators 14 on the outside of a surface 1a of the radio concrete installation housing opposite the coupling surface 1b for displaying the height of a concrete layer that can be applied to the outside of the surface 1a, the one or more elongated height indicators 14 protrude in the direction of the normal vector N1 of the surface 1a. The ones in the Figures 1 and 2 The number of elongated height indicators 14 shown is merely exemplary and not restrictive.

The radio installation housing 1 and the light installation housing 2 can form a system 3 that can enable wireless communication of lights in concrete buildings. This system is an example of the system according to the second aspect of the invention. The above description of the system according to the second aspect is correspondingly applicable to the system 3 of Figures 1 and 2 .

In Figure 2 The state is shown when the radio installation housing 1 is connected to the light installation housing 2. It is also shown how these two installation housings can be installed or cast in concrete 4, for example in a concrete ceiling.

In Figure 2 It can be seen that the optional second spacers 15 of the radio installation housing can determine a thickness of the concrete 4 with which the decoupling surface 1b is covered. Consequently, the thickness of the concrete layer 4 can be determined by the second spacers 15, through which electromagnetic waves (e.g. radio waves) coupled out via the decoupling surface 1b are guided or must propagate in order to go outside the concrete 4, for example into the space of the concrete ceiling 4 , to get.

Furthermore, you can in Figure 2 recognize that the area of the concrete in which the radio concrete installation housing 1 is arranged in the concrete 4 can be displayed by the optional height displays 14. In addition, a height of the concrete layer above the wireless concrete installation housing 1 can optionally be determined using the height displays 14.

The Figure 3 also shows the state when the radio installation housing 1 is connected to the light installation housing 2 and these two installation housings are in concrete 4, for example in a concrete ceiling, installed or cast. The radio installation housing 1 and light installation housing 2 of the Figure 3 corresponds to the radio installation housing 1 and light installation housing 2 Figures 1 and 2 , whereby the radio installation housing is the Figure 3 an additional optional feature compared to the Figures 1 and 2 having. Consequently, the description is the Figures 1 and 2 for the radio installation housing 1 and light installation housing 2 Figure 3 correspondingly applicable and the following essentially describes the additional optional feature of the radio installation housing 1 Figure 3 described.

As in Figure 3 shown, the radio concrete installation housing 1 can have a decoupling unit 17 for decoupling the electromagnetic waves (for example radio waves) on the outside of the decoupling surface 1b.

The material, the geometric shape and/or dimensioning of the decoupling unit 17 can be designed such that the decoupling unit 17 supports, for example reinforces, a decoupling or radiation of electromagnetic waves (e.g. radio waves) from inside to outside of the radio concrete installation housing 1. The material, the geometric shape and/or dimensioning of the decoupling unit 17 can be designed such that the decoupling unit guides the waves to be decoupled in a specific direction, for example in the direction of the normal vector N2 of the decoupling surface 1b, to the outside of the radio concrete installation housing 1 and consequently decoupled.

The decoupling unit 17 is at least partially made of a material that is permeable to the electromagnetic waves, such as plastic. The decoupling unit 17 can have metal or a metal coating in such a way that the decoupling unit 17 has the function of a waveguide.

As in Figure 3 shown, the optional second spacers 15 can be provided on the outside in the area of the coupling-out surface 1b in such a way that they protrude from the coupling-out unit 17 in the direction of the normal vector N2 of the coupling-out surface 1b.

That in the Figures 1 to 3 The radio concrete installation housing 1 and luminaire concrete installation housing 2 shown can be used for in-situ concrete with local formwork (ie a Concrete component (e.g. concrete ceiling) is cast on site using formwork) or used in a factory for the production of a ready-made concrete (e.g. precast concrete ceiling).

Figure 4 shows two schematic sectional views of an example of a preferred embodiment of a radio concrete installation housing according to the invention.

The Figure 4A shows the one in the Figure 2 components shown, ie the radio concrete installation housing 1 and light concrete installation housing 2 installed or cast in the concrete 4 Figure 2 . The Figure 4B shows the one in the Figure 3 Components shown, ie the radio concrete installation housing 1 and light concrete installation housing 2 installed or cast in the concrete 4 Figure 3 . The description of the Figures 1 to 3 is correspondingly for those in the Figures 4A and 4b Components shown apply.

Figures 5 and 6 each show a schematic longitudinal view of an example of a preferred embodiment of a radio concrete installation housing according to the invention.

This in Figure 5 The radio installation housing 1 and light installation housing 2 shown corresponds to the radio installation housing 1 and light installation housing 2 of the Figure 2 in the event that the radio installation housing 1 and light installation housing 2 are used on a prefabricated concrete ceiling (e.g. prefabricated concrete stretch ceiling) with local concrete topping. The description of the Figures 1 to 4 is therefore for the radio installation housing 1 and light installation housing 2 Figure 5 accordingly applicable and the following essentially explains differences with regard to the in Figure 2 Installation housings shown are described.

Since, in the case of a prefabricated concrete ceiling with local concrete topping, the radio installation housing and light installation housing are already at least partially installed in a concrete layer 4a (ie the precast concrete ceiling 4a), the radio installation housing 1 can Figure 5 do not have the optional second spacers, since the covering of the coupling surface 1c with concrete can be determined in the factory by the already existing concrete layer 4a. To form the finished concrete component 4, for example a concrete ceiling, further concrete can then be applied or poured on site onto the already existing concrete layer 4a (ie the finished concrete ceiling 4a).

This in Figure 6 The radio installation housing 1 and light installation housing 2 shown corresponds to the radio installation housing 1 and light installation housing 2 of the Figure 3 in the event that the radio installation housing 1 and light installation housing 2 are used on a prefabricated concrete ceiling (e.g. prefabricated concrete stretch ceiling) with local concrete topping. The description of the Figures 1 to 4 is therefore for the radio installation housing 1 and light installation housing 2 Figure 6 accordingly applicable and the following essentially explains differences with regard to the in Figure 3 Installation housings shown are described.

Since, in the case of a prefabricated concrete ceiling with local concrete topping, the radio installation housing and light installation housing are already at least partially installed in a concrete layer 4a (ie the precast concrete ceiling 4a), the radio installation housing 1 can Figure 6 do not have the optional second spacers, since the covering of the decoupling unit 17 with concrete can be fixed in the factory by the already existing concrete layer 4a.
