Description

The invention relates to an electrical/electronic device for building installation technology, with a central piece surrounded by a cover frame and a base part, wherein a power supply unit can be fixed to the base part, which comes into contact with the base part.

In the prior art, such electrical or electronic devices are known in a variety of designs. The aforementioned electrical or electronic devices are often designed as protective contact sockets, orientation lights, data connection devices, switching devices, dimmers and so on. They are intended for the electrical connection of consumers and/or for influencing connected actuators, such as lighting devices, roller shutter controls, blind controls, heating controls and so on. Electrical/electronic devices are now also known which are designed as protective contact sockets and also have a USB connection.

Furthermore, such electrical or electronic devices are also known as presence detectors from the state of the art. They make it possible to detect the presence of people, whereby further actions can be triggered in response to the detection of presence. Presence detectors help to save energy, especially in building installations or home automation. After detecting the presence of a user, for example, lights can be switched on or the temperature of the room in which the presence detector is located can be regulated.

Presence detectors generally use so-called PIR sensors (pyroelectric infrared sensors). This sensor detects the heat radiation from living beings. Every body whose temperature is above absolute zero emits electromagnetic radiation. In humans, this radiation is in the infrared wavelength range between 800 nm and 1.5 mm. This infrared radiation cannot be perceived by the human eye, but is detected by PIR sensors.

Additional components, such as light sensors, can also be used to adjust the brightness of lamps according to the detected presence of a user. These diverse applications also make it possible to implement security concepts in buildings. For example, it is possible to implement security displays and/or wayfinding systems.

A wayfinding system is, for example, provided by the EN 2019 130 700 A1 disclosed. A dynamic wayfinding system is formed by recording relevant physical variables for route guidance, with a display device controlling and displaying pre-stored images on the dynamic display device depending on the relevant physical variables.

Safety indicators or orientation lighting have the disadvantage that, in addition to a presence detector, devices are required to illuminate a section of a building. Lighting that is also part of the presence detector can, due to the light emitted, hinder other components of the presence detector, such as sensors.

The invention is therefore based on the object of specifying an electrical or electronic device for building installation technology, by means of which orientation lighting is made possible with little installation effort, while at the same time other components, such as sensors, are minimally influenced by the lighting.

This object is achieved in the present invention by the features of the characterizing part of patent claim 1, firstly in that a lighting device is provided through which light can be emitted, that an at least partially translucent section is provided in the cover frame through which the emitted light of the lighting device can emerge, that a shading element is arranged on the cover frame in such a way that the light emitted by the lighting device can be at least partially blocked by the shading element.

The cover frame is a panel for installing the presence detector in a house installation. The cover frame protects and conceals small electronic components, ensuring a more aesthetic appearance when installed.

The central piece also serves as protection for electrical contacts. The power supply unit is an additional component that can have a housing and can be attached to the base part. The modular design means that different power supply units can be used for different applications, whereby the base part remains unchanged.

The power supply unit can be detachably connected to the base part. Detachable in this context means that the power supply unit can be removed from the base part without causing any damage.

The lighting device can be an independent unit that has its own power supply and can be detachably connected to the presence detector, for example. The lighting device is preferably supplied via the power supply of the presence detector. For this purpose, the lighting device can have corresponding electrically conductive contacts that are connected to the power supply unit. The lighting device can have corresponding lamps that can emit light. The lamps are preferably LEDs. However, other lamps known from the prior art are also conceivable.

The shading element is a structural element through which light can exit through the translucent section. The shading element can be arranged and designed in such a way that certain areas within the presence detector are not or only barely illuminated by light from the lighting device. The shading element can be designed as a shadow gap in conjunction with housing parts of the electrical or electronic device, with the shadow gap describing a space between the housing part and the shading element, which is formed by an offset arrangement of the two elements relative to one another.

Further preferred embodiments of the invention result from the remaining features mentioned in the subclaims.

In a first embodiment of the electrical device according to the invention, it is provided that the cover frame is ring-shaped and that the translucent section is ring-shaped. In this context, ring-shaped can mean all-round. A ring shape can be round or have several corners. A user can recognize the emitted light as a clear geometric shape through a translucent section all the way around, which allows the user to directly determine that the emitted light comes from the electrical or electronic device.

In a further preferred embodiment of the electrical device according to the invention, it is provided that the translucent section is formed by a recess or that the translucent section comprises an at least partially transparent material. The translucent section can be a transparent section in a wall of the housing of the presence detector through which light can emerge. Alternatively, the translucent section can also be formed only by a recess in a part of the housing. Preferably, the translucent section is formed in the cover frame, wherein the lighting device can be arranged behind the cover frame in such a way that the light can emerge in a directed manner from the translucent section.

In a further preferred embodiment of the electrical device according to the invention, it is provided that the cover frame can be detachably connected to the electrical device, in particular by means of a locking mechanism. The cover frame can therefore be clipped onto the electrical or electronic device. If the lighting device is arranged behind the cover frame, the lighting device can be quickly serviced or replaced by removing the cover frame. The lighting device can also be clipped into the housing of the electrical device, for example, whereby contacts for the electrically conductive connection are simultaneously connected to corresponding contacts when the lighting device is inserted into a housing of the electrical or electronic device.

In a particularly preferred embodiment of the electrical or electronic device according to the invention, it is provided that the lighting device emits light in the RGBW spectrum, in particular in the colors white, red, yellow and green depending on the situation. The situations in which colored lighting is desired can be diverse. Preferably, the electrical or electronic device is an element of a building installation or home automation. The electrical or electronic device can communicate with other devices in the system using a wireless or wired connection. The colored lighting can then be used, for example, as a warning if one or more sensors in the system detect physical quantities that are above a predetermined limit. In this case, the lighting can be changed to the color red by the lighting device as a warning. It is also conceivable that the lighting device emits green light permanently if all physical quantities detected by any sensors are below a predetermined limit.

In a further advantageous embodiment of the invention, it is provided that the light of the lighting device can be emitted in a pulsating manner. Pulsating can also mean flashing or another repetitive change in the emitted light, particularly in terms of brightness.

In addition, in a further embodiment of the invention, it can be provided that a relay is electrically connected to the lighting device. It can be provided that the lighting device is switched on or off when the relay module is switched. In this way, it is possible for the lighting device to be controlled locally. The relay can be a mechanical or electronic relay, depending on the application.

In a particularly advantageous embodiment of the electrical or electronic device, the central piece has at least one sensor for detecting presence, and the at least one sensor is covered by a lens. The sensor can be a sensor commonly used for presence detectors, for example a PIR sensor as mentioned above. A pyroelectric material in the form of a polarized crystal is used. When electromagnetic or thermal radiation hits the pyroelectric material, it is absorbed. The resulting temperature difference changes the polarization of the crystal, and this change is accompanied by a change in the electrical potential. The electrical potential can be registered using opposing electrodes. It would also be conceivable to use an HF sensor that actively emits high-frequency waves. Movements in a detection area are detected using the Doppler radar principle.

The lens can be a cylindrically curved Fresnel lens. A spherical lens, for example made of plastic, would also be conceivable. By designing it as a Fresnel lens, the spatial range of the presence detection sensor can be influenced and adapted to the respective application. On the other hand, the steps of the Fresnel lens in combination with the presence detection sensor result in a spatial expansion of the sensitivity ranges, which improves the detection of spatial changes in heat sources through steeper transitions. The Fresnel lens can be divided into individual sector elements and into several partial lenses for expansion.

In a further embodiment, the central piece can also comprise at least one climate sensor, whereby the climate sensor can detect air humidity and/or a CO2 content and/or a VOC content. The climate sensor as part of the electrical or electronic device can be wireless or wired, for example via a bus system, with other components of a building installation or home automation.

Additionally or alternatively, in a further embodiment of the method according to the invention, it can be provided that the central piece has at least one fine dust sensor and/or a particle sensor for detecting the proportion of PM2.5 and/or PM10 particles. Analogous to climate sensors, the fine dust sensor can also be connected wirelessly or with a cable, for example via a bus system, to other components of a building installation or a home automation system.

For example, the various components of these devices may be housed on an integrated circuit (IC) or on separate IC chips. Furthermore, the various components of these devices may be implemented on a flexible printed circuit sheet, a tape carrier package (TCP), a printed circuit board (PCB), or on a single substrate.

A competent person should also recognize that the functionality of different computer devices may be combined or integrated into a single computer device, or that the functionality of a particular computer device may be distributed across one or more other computer devices. can be made without departing from the scope of the exemplary embodiments of the present invention.

The various embodiments of the invention mentioned in this application can be advantageously combined with one another, unless stated otherwise in individual cases.

The invention is explained below in exemplary embodiments with reference to the accompanying drawings. They show:

• 1 a schematic representation of an electronic device for building installation technology in an exploded view in the form of a presence detector,
• 2 a sectional view of an electronic device for building installation technology according to the embodiment of 1 and
• 3 an enlarged view of the circled area 2 .

1 shows an electrical or electronic device 1 for building installation technology, wherein the electronic device 1 has a cover frame 2 which surrounds a central piece 3 and serves as protection and cover for a base part 4. A power supply unit 5 can be fixed to the base part. The 1 The electronic device 1 shown is designed and set up for flush mounting. In this embodiment, the power supply unit 5 is supplied with energy by means of a bus system, whereby data can be exchanged simultaneously via the bus system. For this purpose, the data from the individual units of the building installation (not shown here) can be bundled and evaluated in a central processing unit.

The electrical or electronic device 1 has a sensor 6 for presence detection, which is 1 is covered by a lens 7. In the present embodiment, the sensor is a PIR sensor. A pyroelectric material in the form of a polarized crystal is used. When electromagnetic or thermal radiation hits the pyroelectric material, it is absorbed. The resulting temperature difference changes the polarization of the crystal, and this change is accompanied by a change in the electrical potential. The electrical potential can be registered using opposing electrodes.

In order to improve the detection of changes and the range, the lens 7 is arranged in front of the sensor 6 for presence detection. In this embodiment, it is a cylindrically curved Fresnel lens. A spherical lens, for example made of plastic, would also be conceivable. The design of this lens 7 can, on the one hand, influence the spatial range of the sensor 6 for presence detection and adapt it to the respective application. On the other hand, the steps of the Fresnel lens in combination with the sensor 6 for presence detection result in a spatial fanning out of the sensitivity ranges, which improves the detection of spatial changes in heat sources through steeper transitions. The Fresnel lens can be divided into individual sector elements and into several partial lenses for fanning out.

In this embodiment, the sensor 6 for presence detection comprises two sensor elements. Due to the fanning out, when an object that is warmer than the background passes through the detection area of the sensor 6, an increased temperature change occurs at the sensor 6, since the warm object is initially only detected by one sensor element through the lens 7. If the movement continues, the temperature change is detected by the second sensor element, while at the same time the first sensor element loses detection of the object. The two sensor elements are internally connected in such a way that one sensor element generates a positive voltage pulse and the other sensor element generates a negative voltage pulse. As a result, the fanning out roughly doubles the signal change during movements by forming the difference.

The electrical or electronic device 1 additionally has a lighting device 8. This serves as orientation lighting, which is integrated directly into the electronic device 1. Energy can be saved by means of orientation lighting. Orientation lighting generally has a lower power consumption than the actual room lighting. If, for example, a user wants to cross a room at night because he wants to use the bathroom, the orientation lighting can be sufficient to adequately illuminate the room for the user for this purpose. The electronic device can accordingly be connected to the lighting device 8 in such a way that it is only switched on when the presence of a person is detected. The lighting device 8 is integrated in the presence detector 1 in such a way that it is covered by the cover frame 2, wherein a translucent section 9 is formed in the cover frame 2, through which light emitted by the lighting device 8 can pass. The translucent section 9 is ring-shaped in this embodiment. mig, i.e. surrounding the central piece 3 or the lens 7.

In order not to unnecessarily distort further measurements, for example a brightness detection of the sensor 6 for presence detection, the lighting device 8 is integrated in the presence detector 1 in such a way that a shading element 10 blocks the light in such a way that the light emitted by the lighting device 8 does not hinder the sensors for brightness detection in the measurement. The shading element 10 serves as a shadow gap in interaction with the wall of the housing of the presence detector.

2 shows a sectional view of the electrical or electronic device according to 1 It can be seen that several sensors 6 are provided for presence detection, which are arranged in different orientations to one another in order to detect as large an area of a room as possible. The electrical or electronic device 1 in the form of a presence detector is preferably mounted on the ceiling of the room so that the room can be scanned or viewed from above. The curved lens 7 helps with detection in a radius appropriate for the monitored room.

In addition, it can be seen that a light guide 11 of the lighting device 8 is arranged circumferentially around the lens 7. It can be seen that the cover frame 2 is also arranged circumferentially around the lens 7.

In 3 is an enlargement of the circled area in 2 shown. The interaction of the lighting device 8 of the shading element 10 is visible. The shading element 10 is designed as a projection 12 on the cover frame 2. The part of the cover frame 2 that is connected to the housing of the electronic device 1 surrounds the light guide 11 of the lighting device 8 from a first side. In this embodiment, the shading element 10 is designed such that only a comparatively small area 13 of the light guide 11 is not covered by the shading element 10 or other opaque elements of the electronic device 1. The emitted light of the lighting device 8 thus only passes through the small area. The translucent section 9 is conical so that the area 13 can expand to the size of the translucent area 9. In this way, the size and visibility of the surrounding translucent section 9 can be adapted to the respective application.
