Description

The technical field of the present disclosure generally relates to luminaires. In particular, the present disclosure relates to a luminaire or light fixture with adjustable light output.
Luminaires, e.g. LED (light emitting diode) luminaires with adjustable light parameters are known. Further, luminaires controllable by a mobile app or computer, e.g. via wireless or wired communication, physical buttons, knobs or touch panels are known. However, it is often difficult to strike a balance between professionalism and operability, resulting in a low user enjoyment. For instance, for computer- or app-controlled luminaires, additional devices, components or even an entire system are required to carry out a control operation, making such systems not particularly user-friendly, especially for many simple applications. Luminaires controllable by gestures or voice are known as well. However, gesture- and voice-controls suffer from poor recognition and is prone to misinterpretation of the user's intention.
The aim of the present application is to provide a luminaire that can be easily and intuitively controlled and can offer an improved user experience.
In order to solve the above problem, a luminaire or light fixture is provided. The luminaire comprises one or more light sources with at least one adjustable light parameter. In particular, the luminaire may comprise a number of tuneable light sources to provide an adjustable combined light effect.
The luminaire further comprises a driver for driving the at least one light source. The driver may comprise a single-channel and/or multi-channel driver modules for driving the at least one light source. The luminaire also comprises a control module or controller for controlling the driver. The control module may comprise one or more lighting control modules to control the status of the at least one light source, in particular, by accordingly controlling the driver.
The luminaire may comprise at least one stationary part and at least one mobile or movable part. The at least one stationary part may comprise a housing or luminaire body e.g. with a stand for its positioning and/or a mounting base for its mounting on a mounting surface. The at least one mobile part may be configured such that it can be moved by the user, in particular, relative to the at least one stationary part of the luminaire.
The luminaire further comprises a motion detection system for capturing a movement of the luminaire and/or the at least one mobile part of the luminaire, the motion detection system being operationally connected to the control module. The motion detection system may, in particular, comprise one or more sensors configured to capture a translatory movement, a rotation movement, orientation and/or shaking of the luminaire and/or the at least one mobile part. In particular, the motion detection system may comprise one or more gyroscopes, accelerometers, and/or one or more further sensors designed to detect orientation and movement of the luminaire and/or the at least one mobile part.
The control module is configured to control the at least one light source at least partially based on the movement of the luminaire and/or the at least one mobile part, captured by the motion detection system.
In particular, the control module may be configured to control the light output of the at least one light source by accordingly controlling the driver, at least partially based on the motion captured by the motion detection system. The control module may be, in particular, configured to capture a current state, e.g. current operation or illumination state, of the luminaire and to adjust the light output of the at least one light source at least partially based on the current state of the luminaire. In particular, depending on the current state and the movement of the at least one mobile part, captured by the motion detection system, the control module may switch on or off the luminaire, initiate or stop a color loop regime, adjust CCT (Correlated Color Temperature) and/or brightness of the output light. In case when the control is based on the movement of the luminaire as a whole, the luminaire may be referred to as a mobile luminaire.
The luminaire is particularly comfortable and user-friendly, as the luminaire can be controlled by simply moving the at least one movable part, without the need for additional devices to control the light output. Thus, simply by moving the mobile part, the user can provide an interactive feedback to adjust the light output, resulting in improved usability and user enjoyment. Thus, the luminaire represents a simple, installation-free and playfully controllable lighting fixture with an enhance user experience.
Thus, a movement of the at least one mobile part can be interpreted by the motion detection system as a user command for controlling the luminaire. The physical interaction of the user with the at least one mobile part of the luminaire can provide a feedback to the luminaire for changing its current operation regime or adjusting its light output. By employing such interaction feedback, the usability of the luminaire and the user experience can be greatly enhanced.
The at least one mobile part can be dimensioned smaller than the luminaire and/or configured such that it is easily held in the hand for carrying out a movement. Thus, even large luminaires which are not suitable to be held in the hand can be easily controlled by limiting the movement to the at least one mobile part.
As a result, the at least one mobile part can thus act as a smart component that responds to user interactions, such that the display or operational status of the luminaire can be easily changed by simply moving, e.g. rotating or tapping the smart components of the lighting fixture.
The motion detection system may comprise an inertial measurement unit (IMU) for capturing a movement of the at least one mobile part and a microcomputer unit (MCU) configured to convert movements captured by the inertial measurement unit into lighting commands. The IMU may include, in particular, one or more gyroscopes and/or magnetometers configured to capture movements, such as rotation and swings, of the at least one mobile part caused by user actions. Thereupon, these actions can be converted by the MCU into lighting control commands.
The motion detection system may be at least partially integrated in the control module of the luminaire. By integrating the IMU and the MCU controlling the IMU into a single control module, the motion control capabilities can be easily implemented in a luminaire. In particular, the controlling module can be easily integrated into luminaires without any extensive mechanical or structural adaptation measures.
The at least one mobile part may comprise at least one part movably attached to the at least one stationary part. In such embodiments, the luminaire can be controlled by moving the movably attached part relative to the at least one stationary part, without having to separate them from each other.
In some embodiments, the at least one mobile part comprises at least one detachable mobile part. In such embodiments, the at least one mobile part can be separated from the at least one stationary part and can be thus turned into a standalone device, enabling a remote control of the luminaire.
The at least one mobile part of the luminaire may comprise at least one functional element contributing to a light performance of the luminaire. Thus, functional parts of the luminaire can be converted into smart components used for controlling the luminaire.
The at least one functional element may comprise at least one light beam shaping element for shaping a radiational pattern of the luminaire. In particular, external optical elements accessible by the user can be used as smart components for controlling the luminaire.
The motion detection system may be configured to capture information about the direction, angle and/or speed of movement of the at least one mobile part, wherein the control module may be configured to control the at least one light source at least partially based on the information about the direction, movement angle, speed of movement and/or speed of direction change of the at least one mobile part, captured by the motion detection system. Thus, the user can easily adjust or control the light output by moving the at least one mobile part in different directions, at different speeds and/or at different angles.
In some embodiments, the capturing a movement comprises capturing a movement pattern, e.g. trajectory and/or rotational pattern, of movement of the at least one mobile part. Thus, the user can easily adjust or control the light output, by moving the at least one mobile part in different patterns or along different trajectories.
The luminaire may be a configurable luminaire with a changeable lighting configuration. This allows for lighting curve adjustments and posture-specific custom configurations. For instance, the change of the light configuration may comprise choosing a HCL (Human-Centric Lighting) curve, representing a time dependence of light parameters, out of a set of HCL curves stored in a memory unit of the control module, according to the user's preferences.
In some embodiments, the luminaire comprises one or more built-in configuration module for changing the lighting configuration at least partially based on the movement captured by the motion detection.
Alternatively or additionally, the luminaire may comprise one or more external configuration modules for changing the lighting configuration at least partially based on inputs received from an external input device. The external input device may be a server, personal computer, or any mobile device with a suitable user interface. The external device may be wirelessly, e.g. based on Bluetooth or other protocol, and/or wired connected with the luminaire over a corresponding interface of the luminaire.
In some embodiments, the at least one stationary part of the luminaire is configured as detachable and/or moveably mountable luminaire body. In particular, the stationary part or luminaire body may be attached to or detached from a mounting surface depending on the users wishes. Further, the luminaire body may be movable in the mounted state, i.e. even without detaching the luminaire body from the mounting surface. Thus, the luminaire can be even moved as a whole even without changing its location.
In some embodiments, the stationary part comprises a mounting base configured for mounting the luminaire on an essentially flat mounting surface. The mounting surface can in principle be any suitable surface in any location where, for example, the placement of the luminaire is desired. The mounting surface can be for instance a wall- or ceiling surface, a bottom surface of a shelf or cabinet, or any inner surface of a cabinet, e.g. cupboard or wardrobe.
The mounting base may comprise a magnetic material or magnet for magnetically attaching the stationary part of the luminaire to the mounting surface. Due to the magnetic material in the mounting base or magnetic base, the luminaire can be easily, in particular, toollessly attached to a mounting surface of a metallic support or a support comprising a magnetic, in particular, ferro-magnetic, material. In some embodiments, the luminaire may comprise a detachable magnetic plate and/or an adhesive film for mounting the luminaire on the mounting surface. Due to the magnetic plate and/or adhesive tape, the luminaire can be also easily mounted to any non-magnetic support.
In some embodiments, the luminaire comprises at least one power supply unit, in particular, with a rechargeable battery, for autonomous power supply of the at least one stationary part and/or at least one mobile part of the luminaire. Due to the autonomous power supply, the luminaire can be operated even at places without direct access to the power grid. The luminaire may comprise one or more power supply ports and/or inductive charging ports for connecting the luminaire, in particular, the at least one stationary and/or the at least one mobile part to an external power supply. In some embodiments, a USB-C or USB Type-C compact port as a power supply port is used. By connecting the power supply port to the external power supply, the autonomous power supply can be recharged, when necessary.
In some embodiments, the luminaire comprises a communication interface for receiving user commands and the control module may be configured to control the driver at least partially based on the user commands received via the communication interface. In particular, the control module may be configured such that the at least one light parameter is adjusted according to the user commands received via the communication interface.
The communication interface may be configured for wirelessly communicating with a communication interface of a smart device comprising a user interface such that the control module can be configured at least partially based on the user inputs received via the user interface of the mobile device. In particular, the control module may be configured such that the settings of the luminaire, e.g. preset light scenarios, can be modified by the user using e.g. using a proprietary app installed on the mobile device.
In the following description, details are provided to describe the embodiments of the present specification. It shall be apparent to one skilled in the art, however, that the embodiments may be practiced without such details.
Some parts of the embodiments have similar parts. The similar parts may have same names or similar part numbers. The description of one part applies by reference to another similar part, where appropriate, thereby reducing repetition of text without limiting the disclosure.

Fig. 1 shows a schematic perspective view of a luminaire according to an embodiment. In the shown embodiment, the luminaire 1 comprises an essentially disc-shaped stationary part 2 and an essentially disc-shaped mobile part 3 attached to the stationary part 2. The stationary part 2 of the luminaire 1 is mounted on an essentially flat mounting surface 4. The luminaire 1 shows an axial symmetry, with a symmetry axis 5 essentially perpendicular to the mounting surface 4, the stationary part 2 and the mobile part 3.
The mobile part 3 is movably attached to the stationary part 2 such that the mobile part 3 can be manually moved by the relative to the stationary part 2.

In the shown embodiment, the mobile part is attached to the stationary part 2 in such way that it can carry out a translatory and/or rotational movements, indicated by arrows, at least in a certain range. In some embodiments, the mobile part 5 can be rotated around the symmetry axis 5, without any angular limitation.
Fig. 2 shows a schematic side view and a top view of a luminaire according to another embodiment.
In the embodiment of Fig. 2, the luminaire 1 is configured as an axially symmetric table lamp with a vertical symmetry axis 5. The luminaire 1 comprises a stationary part 2 in the Form of a lamp stand and a mobile part 3 configured as a lamp shade which is movable mounted on the lamp stand.
On the right side of Fig. 2, a schematic top view of the luminaire 1 is shown. The arrows in the right side of the Figure symbolize exemplary patterns of movement the mobile part 3 can carry out under physical interaction from the user.
In particular, the lamp shade can be moved upwards, downwards, sidewards and/or in an oblique direction relative to the lamp stand, as indicated by the direction arrows, symbolizing a horizontal movement (arrow X), a vertical movement (arrow Z) and an oblique movement (arrow W), respectively.
Further, the lamp shade can be turned clockwise and/or anticlockwise, as indicated by the bent arrow.
The movements of the mobile part 3 can be converted into lighting commands, e.g. On/Off, Level (brightness) adjustment, CCT adjustment, Scene adjustment, Color Loop exchange, Animation etc, enabling intuitive and user-friendly operation of the luminaire 1.
Fig. 3 shows a schematic perspective view of a luminaire according to a further embodiment. In the embodiment of Fig. 3, the luminaire 1 corresponds essentially to the embodiment of Fig. 1, wherein the mobile part 3 is configured as a removable part which can be separated from the stationary part 2.
On the righthand side of Fig. 3, the mobile part 3 is separated from the stationary part, revealing further details of the luminaire 1. In particular, the luminaire 1 comprises a number of light sources 6 arranged in a circular manner around the stationary part 2.
Similar to the embodiment of Fig. 1, the stationary part 2 and the mobile part 3 both have a disc-shape, the mobile part 3 having a bigger diameter than the stationary part 2, such that it can serve as a lamp shade, at least partially covering the light sources 6 from a direct view.
In some embodiments, the mobile part 3 is configured as a light shaping element, in particular, as an at least partially translucent and/or transparent optical element. For instance, the mobile part 3 may comprise a diffusively scattering optical body, such that the light generated by the number of light sources 6 can be diffusely scattered by the mobile part 3. In some embodiments, the mobile part 3 may comprising a light reflecting front coating, such the light diffusively scattered inside the body can escape from a circumferential side wall of the mobile part 3.
Fig. 4 shows a schematic perspective view of a luminaire according to a still another embodiment. The embodiment of Fig. 4 essentially corresponds to the embodiment of Fig. 3, wherein the mobile part 3 is configured as a bendable or deformable part which can be manually deformed by the user.
In particular, Fig. 4 shows a hand 7 holding the mobile part 3 of the luminaire 1 in a state in which the mobile part 3 is deformed and separated from the stationary part 2.
In some embodiments, the mobile part is elastically deformable such that it re-acquires its original shape, e.g. disc-shape, after the physical impact has ended. The deformable mobile part may comprise a silicone and/or plastic material which is easily deformable and can also serve as a translucent and/or transparent optical medium.
In some embodiments, the mobile part 3 is magnetically attachable to the stationary part 2 such that it can be easily separated from the stationary part 2 by pulling it away from the stationary part 2, as shown in Figs. 3 and 4 above. The internal circuits of the stationary part and the mobile part may be connected to each other e.g. by means of connectors, metal contacts and/or wireless or inductive coupling.
Fig. 5 shows a schematic top view of a luminaire according to a further embodiment. The luminaire comprises a stationary part 2 configured as a housing and a mobile part 3 configured as a translucent optical cover, a light source being arranged in the housing behind the translucent optical cover. The luminaire 1 comprises a motion detection system, a driver for driving the light source, a control module for controlling the light output of the light source and a power unit or battery for autonomous power supply of the luminaire 1. These components are not shown in Fig. 5.
Fig. 6 shows a schematic side view of a luminaire according to Fig. 5. As seen from the side view of Fig. 6, the luminaire has a flat bottom or mounting base 8 opposite to the translucent optical cover 3 which has a dome shape with a convex profile. The mounting base 8 may comprise a magnetic material or magnet and/or adhesive for mounting the luminaire on an essentially flat surface.
Fig. 7 illustrates an operation of a luminaire according to an embodiment. In particular, Fig. 7 shows a luminaire 1 which may be fixed with a magnet to a mounting surface such that the mobile part 3 and/or the whole luminaire 1 can be moved or rotated by the user. In particular, the user can easily detach the magnetically attached luminaire from the mounting surface and move the whole luminaire 1, as a mobile luminaire, for controlling the light output of the luminaire 1. In this illustrative example, the rotational movement caused by a user hand, symbolized by a rounded arrow (on the left side of Fig. 7), is detected by the motion detection system, and the light source is turned on by the control module, corresponding to the state shown on the right side of Fig. 7. Basically, it may be any other movement, depending on configuration, e.g. a combination of translatory and/or rotational movement and/or shaking which can be used by the user to control the luminaire 1.
Fig. 8 shows some translatory movements which can be used for controlling the luminaire. In particular, Fig. 8 shows a top view of the luminaire 1 according to an embodiment together with arrows X, Z and W symbolizing a horizontal movement (arrow X), a vertical movement (arrow Z) and an oblique movement (arrow W), respectively. In some embodiments, the motion detection system may be configured to capture such a translatory movement of the mobile part 3 and/or the whole luminaire 1 and the control module may be configured to control or adjust the light output of the luminaire 1 accordingly. In particular, the control module may be configured to interpret a captured translatory movement as a user command to control the light output of the luminaire 1.
Fig. 9 shows some rotational movements which can be used for controlling the luminaire. In particular, Fig. 9 shows a top view of a luminaire 1 according to an embodiment together with rounded arrows symbolizing rotational movement of the mobile part 3 or luminaire 1.
In particular, the mobile part and/or the whole luminaire 1 may be rotated clockwise, symbolized by a rounded arrow at the top left corner of Fig. 9, or anticlockwise, symbolized by a rounded arrow at the top right corner of Fig. 5. The luminaire 1 can also be rotated in alternating directions, e.g. to carry out a flip-flop rotation, symbolized by an arrow in the bottom of Fig. 9.
The motion detection system may be configured to capture such a rotatory and/or flip-flop movement of the mobile part and/or the whole luminaire 1 and the control module may be configured to control or adjust the light output of the luminaire 1 accordingly. In particular, the control module may be configured to interpret a captured rotatory movement as a user command to control the light output of the luminaire 1.
In some embodiments, the control module is configured to control the light output of the luminaire at least partially based on a direction, speed and/or rhythm of a translatory and/or rotatory movement.
In particular, direction, speed and/or rhythm of a translatory and/or rotatory movement can be interpreted by the control module as a command to e.g. adjust the illumination level, Onn/Off the light, adjust the CCT, change the illumination scene or color loop, start/stop an animation etc.
Fig. 10 shows an exemplary implementation scheme of a motion control according to an embodiment. In the exemplary implementation scheme of Fig. 10, three different lighting statuses of the luminaire 1 are shown. In the leftmost position in Fig. 10, the luminaire 1 is in an initial state, e.g. generating a light with a certain color temperature. Later, a left rotation of the mobile part of the luminaire 1 is carried out by the user.
The left rotation, symbolized by a solid round arrow, is detected by the motion detection system. The control module interprets the left rotation, e.g. based on a look-up table stored in a memory unit of the control module, as a command to reduce the cooler temperature, thus bringing the luminaire to a second state (middle in Fig. 10) in which the luminaire generates a cooler light. After that, the user holds the mobile part, and/or the whole luminaire, and draws a circle clockwise, symbolized by an open round arrow, which is detected by the motion detection system.
The control module interprets the circular movement, e.g. based on a look-up table stored in the memory unit of the control module, as a command to gradually increase the brightness of the output light of the luminaire, leading to the third state (the right most state in Fig. 10). The transitions from the first state to the second state and from the second state to the third state are symbolized by horizontal arrows. Depending on the embodiment, the motion control can be realized by moving the mobile part relative to the stationary part or by moving the luminaire 1 as a whole.
Fig. 11 shows a further exemplary implementation scheme of a motion control according to an embodiment. In the exemplary implementation scheme of Fig. 11, the luminaire 1 is in a first state, e.g. generating a light with a first spectral characteristics, after that the mobile part and/or the luminaire 1 as a whole is shaken which is detected by the system and interpreted by the control module as a command to run a color loop. Thereupon, the control module brings the luminaire from the first state (left in Fig. 11) to the color loop state (right in Fig. 11). In the color loop mode, the spectral characteristic of the light is being steadily changed such that the light color changes gradually. The transition from the first state to the second (color loop) state is symbolized by a horizontal arrow.
Fig. 12 shows a side view of a luminaire according to an embodiment. In the shown embodiment, the luminaire 1 comprises a power supply port 9 in the lower part of the housing.
In some embodiments, the mobile part in the form of a translucent optical cover is configured as a push button which can be manually operated by the user. In particular, by pressing down, e.g. towards the mounting base, the translucent optical cover can be deformed or displaced such that at least one mechanical switch (not shown) can be activated which can be registered by the control module as a user input by a control module. Thus, pushing the translucent optical cover 3 can serve as an addition input, especially in addition to the motion control, to control the luminaire.
The luminaire 1 may comprise a PCB (printed circuit board) with a light engine mounted on the PCB. The light engine may comprise a number of LEDs mounted on the PCB. In some embodiments, the light engine comprises one or more red, green, blue and/or white LEDs with different color temperatures.
By combining the lights generated by the red, green and white LEDs, in different proportions, a light with different color or and/or a white light with different color temperature can be generated.
The luminaire may comprise a power supply unit with a rechargeable battery. The power supply unit may be connected to the power supply port 9 such that the rechargeable battery of the power supply unit can be recharged by connecting the luminaire 1 to an external power supply by means of the power supply port 9.
On the bottom side of the mounting base 8 an adhesive tape may be provided for attaching the mounting base 8 and/or a magnetic plate (not shown) to the mounting surface. In some embodiments the adhesive tape is a double-sided adhesive tape with a non-adhesive removable foil provided on one or on both sides of the adhesive tape. In some embodiments, the non-adhesive removable foil is provided on one side of the adhesive tape, the other side being attached to the magnetic plate.
Fig. 13 shows a perspective explosion view of the luminaire according to an embodiment. In particular, for a better clarity, Fig. 13 shows the adhesive tape 17 and a magnetic plate 18 in a separated state. In some embodiments, a 3M (Minnesota Mining and Manufacturing Company) adhesive tape is used.
Fig. 14 shows a schematic block diagram of a luminaire according to an embodiment. Some functional parts are implemented in the stationary part 2 and some functional parts are implemented in the mobile part 3.
In the present embodiment, the stationary part 2 comprises a tuneable light module 20, which may comprise a number of light sources 6 with adjustable light parameters. The stationary part 2 further comprises a driver 21 for driving the light module 20. In some embodiments, the driver 21 is a multi-channel driver for driving separate light sources, e.g. LED-Light sources with different colors, e.g. red, green, blue and white LEDs, to generate a combined light with a desired spectral characteristic.
The mobile part 3 of the luminaire 1 comprises a motion detection system 22 with one or more sensors for detecting a motion of the mobile part 3 of the luminaire 1. The motion detection system 22 may, in particular, comprise an inertial measurement unit (IMU) one or more gyroscopes, accelerometers, and/or one or more further sensors designed to detect orientation and movement of the mobile part 3, in particular, relative to the stationary part 2 of the luminaire 1.
The mobile part 3 of the luminaire 1 also comprises a control module 30 comprising a processor 31, a memory unit 32 and a communication interface 33 for communicating with the motion detection system 22 and the driver 21 for driving the light sources 6. The luminaire 1 further comprises a power supply unit 40 for autonomous power supply of the mobile part 3 of the luminaire 1. The power supply unit 40 may comprise a rechargeable battery and a power supply port for connecting the power supply unit 40 with an external power supply 40.
Depending on the embodiment, the stationary part 2 and the mobile part may be connected via wired or wireless communication. In particular, the control module 30 of the mobile part 3 and the driver 21 of the stationary part may be connected via wired or wireless communication, based on different communication protocols.
For instance, the stationary part 2 and the mobile part 3 may be configured to communicate via SPI (Serial Peripheral Interface), I2C (Inter-Integrated Circuit), UART (Universal Asynchronous Receiver/Transmitter), and/or SWS (Single-Wire Serial) communication protocol. In some embodiments, for adjusting the light output of the luminaire 1, a PWM (pulse-width modulation) of LED light sources is applied.
In some embodiments, wireless communication between the stationary part 2 and the mobile part 3 is established based on the NFC (near field communication), BLE (Bluetooth ^® Low Energy) or another wireless communication protocol.
In some embodiments, the power supply port is configured for wirelessly, in particular, inductively, coupling with a power source arranged in the stationary part 2 or an external power source.
Optionally or at least in some embodiments, the mobile part 3 may also comprise a light module with one or more light sources, in particular, with at least one adjustable light parameter and a driver for driving the light modules. The control module 30 may be accordingly configured to control the light module of the mobile part. In Fig. 14, the optional light module 20 and the light sources 6 of the mobile part 3 are shown in dashed lines.
In some embodiments, the stationary part also comprises a motion detection system and a control module, in particular, similar to the mobile part, such that the lighting operation of the stationary part can be controlled by moving the stationary part. This feature can be particularly helpful for the luminaires with a separable mobile part, in case, the mobile part is far away from the stationary part of the luminaire. In such a case, the user can still control the luminaire by handling, in particular, moving the stationary part, according to predefined movement patterns.
The memory unit 32 is configured to store data and machine-readable instructions for the processor 31 for controlling the driver 21. In particular, the memory unit 32 may store instructions for the processor 31 to evaluate data received from the motion detection system 22 in order to interpret a movement captured by the motion detection system 22, and to control the light output of the luminaire 1 by controlling the driver 21, at least partially based on the motion captured by the motion detection system 22.
In some embodiments, the memory unit 32 may contain instructions for the processor 31 to identify a movement pattern based on the movement captured by the motion detection system 22. Further, the memory unit 32 may contain at least one look-up table assigning movements or movement patterns to instructions to the processor 31 to control the driver 21 such that light sources 6 can be controlled based on the movement or movement patent identified by the processor 31.
In some embodiments, the motion detection system may comprise further sensors, in particular, for capturing further actions of the user. For instance, in the case of a deformable mobile part (cf. Fig. 4 above), the motion detection system may comprise one or more deformation sensors, e.g. piezo sensors, embedded in the deformable body of the mobile part. By means of the deformation sensors, the deformation of the mobile part caused by the user's actions can be captured. The control module 30 may be configured to control the light sources 6 at least partially based on the deformation captured by the deformation sensor. Hence, in addition to the motion control, deformation of the mobile part can be used for controlling the luminaire, thus making the luminaire more flexible and user-friendly in operation.
In some embodiments, the luminaire comprises one or more lighting configuration modules which may be part of the control module 30 or a separate module. The lighting configuration module may be configured for changing the lighting or operational configuration of the luminaire at least partially based on the movement captured by the motion detection system 22.
The luminaire 1 may alternatively or additionally comprise one or more external configuration modules for configuring the luminaire 1 at least partially based on inputs received form an external input device or configurator. In particular, in some embodiments, more complex operations can be accomplished by connecting an external configurator.
