Description

[0001] PENDANT LAMP AND METHOD FOR CONTROLLING A PENDANT LAMP

[0002] The invention describes a pendant luminaire for the home with a light source, an adjustment unit, an actuator, a sensor unit, a controller which is intended and suitable for processing the signals detected by the sensor unit and / or for controlling the actuator and / or the adjustment unit, wherein the controller has an AI / ML unit, as well as a method for controlling a pendant luminaire.

[0003] State of the art

[0004] Pendant luminaires are often designed to be height-adjustable in the prior art. If the height of the lamp is adjustable, this is usually done mechanically in the previously known pendant luminaires, particularly through the use of counterweights. Pendant luminaires of the type mentioned above, which have one or two electric motor-driven winding devices for the purpose of adjusting the height of the support element, are also already known from the prior art. Operation is achieved via an external remote control device that operates radio-controlled or based on electromagnetic radiation in the infrared spectral range.

[0005] Such a pendant light is disclosed, for example, in EP 4118378A1. This disclosed pendant light is controlled by hand movements, with the hand movements being detected by suitable sensors. This pendant light has the disadvantage that a user in the immediate vicinity of the pendant light must perform hand movements to adjust the height. Furthermore, other adjustment options for the pendant light, such as changing the illumination in the horizontal direction, are not feasible.

[0006] It is therefore an object of the present invention to provide a pendant luminaire that offers intuitive and simple operation and, in particular, allows the lighting situation to be adjusted conveniently and safely. It is also an object of the invention to provide a method for controlling a pendant luminaire that enables intuitive and simple operation and, in particular, allows the lighting situation to be adjusted conveniently and safely.

[0007] Description of the invention

[0008] This object is achieved by means of the pendant luminaire for the home according to the invention. Advantageous embodiments of the invention are set forth in the subclaims.

[0009] The pendant luminaire for the home according to the invention comprises a socket for accommodating a lamp and / or a lamp. The lamp is the light source in the pendant luminaire. All electrical devices or electrical consumers that serve to generate light are referred to in this document as lamps. A lamp has a light field with a defined area and luminous intensity.

[0010] A pendant luminaire within the meaning of the invention is a luminaire for emitting light whose light field is adjustable in at least one spatial direction. The spatial direction of the light field can be changed horizontally and / or vertically and / or in all directions in between. The pendant luminaire can, for example, be arranged on a room ceiling, with the light field being adjustable by means of a cable construction. The pendant luminaire can, however, also be designed as a floor lamp, for example; use of the pendant luminaire as a desk lamp is also conceivable. Essential to the invention is the adjustability of the light field in its extent and / or direction.

[0011] A home application includes the use of the pendant luminaire in homes and / or office environments, particularly in areas of hybrid use as a home and office environment for home working (home office).

[0012] The pendant luminaire also includes an adjustment unit and an actuator for operating the adjustment unit. The adjustment unit includes one or more motors connected to and driving a suitable adjustment device (e.g., rail, threaded spindle). This allows the light field to be adjusted. Advantageously, the pendant luminaire includes a sensor unit designed and intended to detect the surroundings of the pendant luminaire. Such sensors include cameras, microphones, and motion sensors.

[0013] The pendant luminaire also includes a controller, which is designed and suitable for processing the signals acquired by the sensor unit and / or controlling the actuator and / or the adjustment unit. The controller includes an AI / ML unit. The controller is designed as a microcontroller with a memory and optionally includes a software program for analyzing the sensor data acquired by the sensor unit and for controlling the pendant luminaire. The AI / ML unit (AI / ML) contains stored AI / ML data.

[0014] In a further development of the invention, the pendant light has a camera for environmental analysis and / or a microphone. A camera captures image data of the surroundings of the pendant light, in particular people nearby and the lighting conditions in the room to be illuminated. A microphone captures sound data from the surroundings and can optionally be used to record voice commands.

[0015] In a further development of the invention, the camera is an HD camera with a wide-angle lens. In an optional embodiment, a medium to high wide angle is used. Here, the fields of view are at an angle greater than 60°, preferably greater than 75°, particularly preferably greater than 90°, and especially preferably greater than 120° in the horizontal and / or vertical plane. This ensures that the entire relevant space can be observed with the camera.

[0016] In a further embodiment of the invention, a computer unit is connected to the camera. This can be, for example, a Raspberry Pi. The computer unit is used to evaluate the camera images and control the pendant light. In a preferred embodiment, the computer unit corresponds to the control unit.

[0017] In a further embodiment of the invention, the camera is built into the canopy of the pendant light. This avoids the need for a separate camera unit and simultaneously results in a positioning that provides a favorable perspective for the camera. In an optional embodiment, the camera is directed vertically downwards. This allows, for example, the table and people sitting at the table to be captured from a bird's eye view. If the canopy of the pendant light is not centered above the table, an additional camera module can be provided, or the table and people sitting at the table can be observed from a different perspective.

[0018] In a further embodiment of the invention, the image data captured by the camera is processed in real time by an object recognition library. In an optional embodiment of the invention, the object recognition library includes models from a bird's-eye view.

[0019] In a further development of the invention, the images are scaled, normalized, and / or processed in a standard image and / or color format. This can be, for example, the RGB format. In an optional embodiment of the invention, the noise is reduced and / or the contrast is optimized to improve the detection of the detected objects.

[0020] In one embodiment of the invention, the training data is annotated for at least two different specific classes. These are, for example, person and table.

[0021] In one embodiment of the invention, targeted augmentation methods are used for training. These can include, for example, rotation, mirroring, brightness adjustment, and / or limited perspective distortion. This is advantageous for artificially expanding the training base.

[0022] In a further development according to the invention, the model is fine-tuned through transfer learning and / or targeted hyperparameter tuning. This enables the most precise object recognition possible in the specific application situation.

[0023] In a further development of the invention, the hardware of the system is designed in such a way that stable detection is guaranteed in up to 2 seconds.

[0024] In a further embodiment of the invention, the lighting is controlled adaptively via a trigger system to avoid abrupt or unwanted changes. In a further configuration of the invention, live detection returns coordinates of the detected people and the table. In an optional embodiment of the invention, this position data is then used for automated control of the lighting in the rest of the system.

[0025] In a further advantageous embodiment of the invention, the pendant luminaire can vary its size and position along all axes in space using an adjustment unit. The term "size" encompasses any form of surface enlargement or reduction of the pendant luminaire. Adjustment can be achieved electrically, hydraulically, pneumatically, and / or in other ways.

[0026] In a further embodiment of the invention, the adjustment unit has a height adjustment for the pendant luminaire. The height adjustment allows the light field to be adjusted vertically. Within the context of the present invention, the vertical direction refers to a direction (essentially) along the direction of gravity.

[0027] In a further aspect of the invention, the height adjustment mechanism includes a weight to facilitate height adjustment. In particular, the weight is a counterweight that has a mass substantially equal to that of the socket for accommodating a light source. The counterweight is connected to the socket for accommodating a light source via, for example, a cable structure. During height adjustment, the socket for accommodating a light source is adjusted in a vertical direction, while the counterweight is adjusted in the opposite vertical direction. Therefore, height adjustment requires less effort.

[0028] In a further embodiment of the invention, the adjustment unit has a width adjustment for the pendant light. Width adjustment occurs in the horizontal direction, whereby, in the context of the present invention, the horizontal direction refers to a direction (essentially) perpendicular to the direction of gravity. By adjusting the width, the light field can be changed horizontally.

[0029] In a further embodiment of the invention, the adjustment unit comprises a device for changing the light field illuminated by the pendant luminaire. The light field can be adjusted, for example, in its intensity (light output per area), wavelength (color), extent, and direction.

[0030] In a further development of the invention, the light field is variable in its extent and / or direction. The light field can be varied horizontally and / or vertically, and the area exposed to the light field can also be varied.

[0031] In a further embodiment of the invention, the control system can control the light brightness and / or the light color and / or the flashing rhythm. In addition to changing the light field, its intensity, color, and, if applicable, a flashing rhythm can be adjusted.

[0032] In a further embodiment of the invention, the pendant luminaire has a communication interface coupled to the control system. A terminal device (e.g., smartphone, tablet, PC, notebook) can be connected to the control system via the communication interface. The connection is established via Wi-Fi, for example, but other wireless connections such as Bluetooth, NFC, or other suitable technologies are also possible. Optionally, the connection can also be established via cable. The terminal device optionally has an app with which the control system and thus the pendant luminaire can be configured and controlled.

[0033] In a further embodiment of the invention, communication via the communication interface takes place using Wi-Fi, Bluetooth, NFC, or another technology. A terminal device (e.g., smartphone, tablet, PC, notebook) can be connected to the controller via the communication interface.

[0034] In an advantageous embodiment of the invention, the pendant light can be controlled via a software program, with the software program being executed on a terminal device connected to the pendant light via the communication interface. A user is therefore not required to be in the immediate vicinity of the pendant light. The pendant light can therefore be installed as part of a smart home.

[0035] In a further development of the invention, the pendant luminaire can be configured via the software program. The light field can therefore be configured without a user being in the immediate vicinity of the pendant luminaire. In a further development of the invention, the control is operated via a wall switch. In addition to operation via an app on a preferably mobile device, operation via a fixed wall switch is also possible. This achieves redundancy in the operation of the pendant luminaire.

[0036] In a further embodiment of the invention, the pendant light has a loudspeaker coupled to the control unit. Audio files, such as music, announcements, etc., can be played through the pendant light via the loudspeaker.

[0037] In a further advantageous embodiment, the loudspeaker can be coupled to a terminal device via the communication interface. Audio files stored on the terminal device can thus be played through the pendant light. In a further embodiment of the invention, music and / or other sound files can be sent to the controller via the communication interface and / or played through the loudspeaker.

[0038] In a further embodiment of the invention, the controller is coupled to a memory, with configuration settings stored in the database depending on the situation detected by the sensors of the pendant luminaire. The configuration settings include, for example, height adjustment, width adjustment, and changes to the light field illuminated by the pendant luminaire.

[0039] The object is further achieved by the method according to the invention for controlling a pendant light. Advantageous embodiments of the invention are also set forth in the subclaims.

[0040] The method according to the invention for controlling a pendant light comprises five steps: In the first step, environmental parameters are detected by a sensor unit of the pendant light. The detection is carried out by the sensor unit, which includes, for example, cameras, microphones, and motion sensors.

[0041] In the second step, the recorded environmental parameters are compared with environmental parameters previously stored in a database for the pendant luminaire. The stored environmental parameters are recorded before the pendant luminaire is operated and stored in the database. Stored environmental parameters include, for example, the type and size of the room to be illuminated, the number and location of people in the room, the current lighting situation, and the time of day.

[0042] In the third step, the stored environmental parameters that are most similar to the recorded environmental parameters are determined. Typically, the recorded environmental parameters and the stored environmental parameters do not completely match; therefore, the recorded environmental parameters are analyzed for their similarity to the stored environmental parameters. The environmental parameters that are most similar to the recorded environmental parameters are selected by the controller.

[0043] In the fourth step, the configuration parameters stored for the most similar environmental parameters are read out. The stored environmental parameters are assigned configuration parameters for the pendant luminaire, which are also stored in the database. These configuration parameters are read out by the controller.

[0044] In the fifth step, the configuration of the pendant luminaire is adjusted based on the selected configuration parameters. The environmental parameters that most closely resemble the recorded environmental parameters are selected by the controller. The corresponding stored configuration parameters are read by controller C and also adjusted by the controller. The controller controls the adjustment unit and adjusts and executes the configuration of the pendant luminaire according to the stored configuration parameters. The pendant luminaire is therefore configured and adjusted autonomously without user intervention.

[0045] In a further development of the invention, the determination is carried out by an AI / ML algorithm. Typically, recorded environmental parameters and stored environmental parameters do not completely match; the recorded environmental parameters are therefore analyzed for their similarity to stored environmental parameters using an AI / ML algorithm, thereby increasing the reliability of the determination. In a further embodiment of the invention, the AI / ML algorithm is implemented in the control system of the pendant light. In a further development of the invention, the evaluation of the data recorded by the second sensor is carried out with AI / ML support. The database contains machine learning data, which is used to determine the stored environmental parameters that are most similar to the recorded environmental parameters.

[0046] In a further design, the recorded environmental parameters are analyzed. The recorded environmental parameters are analyzed for their similarity to stored environmental parameters using the controller. This analysis is performed using the AI-ML data stored in the AI-ML unit.

[0047] In a further embodiment of the invention, environmental parameters are recorded for storing configuration parameters in the pendant luminaire's database. Recorded environmental parameters are recorded by the sensor unit and stored in the database to improve the AI / ML algorithm.

[0048] In a further embodiment of the invention, the configuration parameters set by a user of the pendant light for the detected environmental parameters are recorded for controlling the pendant light. The set configuration parameters are created by a user and stored in the database and / or a terminal device.

[0049] In a further embodiment of the invention, the recorded environmental parameters and the configuration parameters related to them are stored in a database. Alternatively, the recorded environmental parameters and the configuration parameters related to them are stored in a terminal device.

[0050] Embodiments of the pendant luminaire according to the invention and of the method according to the invention for controlling the pendant luminaire are shown in a simplified schematic manner in the drawings and are explained in more detail in the following description.

[0058] Fig. 5: Example of the connections of the components of the pendant luminaire

[0059] Fig. 1 shows a side view of exemplary embodiments of the pendant luminaire PL according to the invention. The pendant luminaire PL has the holder H, which in this and all other exemplary embodiments is attached to the ceiling (top) of the room to be illuminated. However, the pendant luminaire PL can also be designed, for example, as a floor lamp, with the holder H arranged on the floor of the room to be illuminated. It is also conceivable to use the pendant luminaire PL as a desk lamp; the holder H is then arranged on the desk.

[0060] The holder H comprises the controller C, an actuator A, and a first motor M1. The first motor M1 is connected to the cable structure K via a pulley arranged in the holder H and drives it. The cables K have current-conducting cables and are connected to the socket for the lamp L and the counterweight W. The second motor M2 and third motor M3, as well as the electrical system for supplying the lamp L, are arranged in the socket for the lamp L (Fig. 1 a). The lamp L is arranged such that light is emitted downwards.

[0061] The first sensor S1, which is designed as a camera for recording images of the surroundings of the pendant luminaire PL, is arranged in the counterweight W. The second sensor S2 is also arranged in the counterweight W and is designed as a microphone for recording ambient noise and voice commands. The counterweight W is dimensioned such that the mass of the counterweight W and the socket for the lamp L are essentially the same. The controller C is connected to the sensors S1, S2, the actuator A, the motors M1, M2, M3 and the lamp L and controls them (see Fig. 5).

[0062] For height adjustment, the pendant luminaire PL has the first motor M1 in the holder H (Fig. 1 b). For this purpose, the controller C controls the first motor M1 such that the motor M1 changes the length of the cable sections K between the holder H and the socket for the light source L. The holder H has a drum for each cable K provided for suspending the pendant luminaire PL, onto which drum a part of the cable K is wound. The motor M1 rotates the drum in order to wind up or unwind the cable K and thus change the length of the cable section K between the holder H and the socket for the light source L. The vertical position of the socket for the light source L is changed by the controller C in accordance with received control commands.

[0063] For reliable detection, an HD camera (S1) with a medium to high wide angle is used, which is connected to a Raspberry Pi (C). The camera (S1) is installed in the canopy (H) of the pendant light (P) and is directed vertically downwards, thus optimally capturing the table and the people sitting below it from a bird's eye view. The image data is processed in real time by an object detection library in the Raspberry Pi (C), with the current focus being on YOLOvß (You Only Look Once, version 8). This library is known for its powerful real-time object detection. Since YOLOv8 is available in Python, our detection algorithm is also implemented in this language. The library offers several pre-trained models that already enable initial object detection. However, these models are not suitable for our use case, as the detection of people and tables from a bird's eye view (from above) is required.

[0064] The images are scaled, normalized, and processed in RGB format to ensure YOLOv8 compatibility. Furthermore, noise is reduced and contrast is optimized to improve recognition. The training data is annotated using CVAT, with two specific classes defined: people and tables. Since the specially generated dataset is limited, targeted augmentation methods such as rotation, mirroring, brightness adjustment, and limited perspective distortion are used to artificially expand the training base. The model is fine-tuned using transfer learning and targeted hyperparameter tuning to enable the most precise object recognition possible in the specific application situation.

[0065] The system is designed to ensure stable detection in up to 2 seconds. The lighting is controlled adaptively via a trigger system to avoid abrupt or unwanted changes. At the end of the live detection process, the coordinates of the detected people and the table are returned. This position data is then used to automatically control the lighting in the rest of the system.

[0066] Fig. 2 shows a side view of exemplary embodiments of the pendant luminaire PL according to the invention for rotating the socket for the light source L about its longitudinal axis. For rotation about its longitudinal axis, the socket for the light source L has the second motor M2. For this purpose, the controller C controls the second motor M2 such that the motor M2 pivots the socket for the light source L about its longitudinal axis. In an alternative embodiment, the motor M2 pivots a cover that covers part of the light source L in such a way that a changed direction of the emitted light is enabled. The rotation changes the direction of the light emitted by the light source L. In this exemplary embodiment, the light is emitted downwards (Fig. 2 a) or upwards (Fig. 2 b). All intermediate directions, including emission of the light through 360° around the longitudinal axis of the socket for the light source L, are possible.

[0067] Fig. 3 shows a side view of exemplary embodiments of the pendant luminaire PL according to the invention for adjusting the width of the socket for the lamp L. For width adjustment, the pendant luminaire PL has the third motor M3 in the socket for the lamp L (Fig. 3 a). For this purpose, the controller C controls the second motor M3 such that the motor M3 drives a threaded spindle. The threaded spindle is connected to the two opposite movable ends E of the socket for the lamp L. The ends E each have lamps like the socket for the lamp L. By moving the movable ends E outwards, the light field emitted by the lamp L is increased (Fig. 3 b), and by moving the movable ends E inwards, it is reduced. The light field emitted by the lamp L is thus changed in its extent. Fig. 4 shows a preferred embodiment of the pendant luminaire PL according to the invention.The PL pendant light incorporates all of the aforementioned components M1, M2, M3, and L for adjusting the light field. The height of the lamp L is adjusted by controlling the first motor M1, the rotation of the lamp L is adjusted by controlling the second motor M2, and the width is adjusted by controlling the third motor M3. The brightness and color of the light, as well as any flashing rhythms of the lamp L, are adjusted by controlling the lamp L. Optionally, sound files can be played by controlling a loudspeaker.

[0068] Fig. 5 shows an embodiment of the connections between the components SE, CE, AE of the pendant light PL and the directions of the data flow during control of the pendant light PL. The sensor unit SE has the two sensors S1, S2, which are connected to the controller C. The control unit SE has the controller C, which is designed as a microcontroller with a memory. The memory optionally has a software program with which the pendant light PL is controlled. The controller C also has a communication interface (not shown) via which an end device (e.g. smartphone, tablet, PC, notebook) can be connected to the controller C. The connection is made via WLAN, but other wireless connections such as Bluetooth, NFC or other suitable technologies are also possible. Optionally, the connection can also be made via cable.The device has an app that can be used to configure and control the C controller and thus the PL pendant light. Optionally, the PL pendant light has a loudspeaker that can also be connected to the device via the communication interface. Music and / or other sound files can be sent to the controller via the communication interface and played through the loudspeaker. The music and / or other sound files are stored on the device and / or optionally in the DB database.

[0069] The controller C is connected to the database DB and to the AI-ML unit KI / ML. The AI-ML unit KI / ML contains stored AI-ML data. The AI / ML unit KI / ML contains machine learning data that is applied to the data acquired by the sensors S1 and S2. The database DB contains stored environmental parameters and stored configuration settings for configuring the pendant luminaire PL. The adjustment unit AE contains the motors M1, M2, M3 and the lamp L, which are connected to the control unit SE.

[0070] To control the PL pendant luminaire, environmental parameters are continuously recorded via the SE sensor unit and sent to the C controller. These recorded environmental parameters include, for example, the number and location of the occupants present in the room to be illuminated, as well as the lighting situation, e.g., due to daylight or other lighting sources arranged in the room. These recorded environmental parameters are analyzed by the C controller with regard to the lighting situation prevailing at the time of recording and compared with the environmental parameters stored in the DB database.

[0071] Controller C then also determines the environmental parameters stored in the database DB that are most similar to the recorded environmental parameters. Typically, recorded environmental parameters and stored environmental parameters do not completely match; therefore, the recorded environmental parameters are analyzed for their similarity to the stored environmental parameters. This analysis is performed using the AI-ML data stored in the AI-ML unit AI / ML. Configuration parameters for configuring the pendant luminaire PL, which are also stored in the database DB, are assigned to the stored environmental parameters. These configuration parameters are read by controller C.

[0072] The environmental parameters that are most similar to the recorded environmental parameters are selected by the controller C, the corresponding stored configuration parameters are read out by the controller C and also set by the controller C. For this purpose, the controller C controls the adjustment unit AE and sets and executes the configuration of the pendant luminaire PL according to the stored configuration parameters. The height of the lamp L is adjusted by controlling the first motor M1, the rotation of the lamp L is adjusted by controlling the second motor M2 and the width adjustment by controlling the third motor M3. The light brightness and light color as well as, if applicable, the flashing rhythm of the lamp L are adjusted by controlling the lamp L. Optionally, sound files can be played back by controlling a loudspeaker. The pendant luminaire PL is therefore configured and adjusted autonomously without user access.Optionally or additionally, the PL pendant light can also be controlled by voice commands received by the second sensor S2. Also optionally or additionally, the PL pendant light can also be controlled by a fixed wall switch.
