DETAILED DESCRIPTION OF EMBODIMENTS

[0040] FIG. 1 shows schematically an embodiment of a system 100 according to the invention for commissioning a lighting device 120 by a wearable device 102 when installing the lighting device 120. The system 100 comprises the wearable device 102 comprising a detection unit 104 arranged for detecting contextual information of the wearable device 102, the contextual information being at least one of an orientation and/or a movement of the wearable device. The system 100 further comprises a receiver 106 arranged for receiving an identifier of the lighting device 120. The system 100 further comprises a processor 108 arranged for determining at least one installation characteristic of the lighting device 120 based on the detected contextual information of the wearable device 102, and for linking the at least one installation characteristic to the identifier. The system 100 also comprises a memory 110 arranged for storing the at least one installation characteristic and the identifier. Upon storing the at least one installation characteristic, the lighting device 120 may be ready to be controlled by any type of control device that is connected to the lighting device 120. The wearable device 102, the receiver 106, the processor 108 and the memory 110 may be interconnected by any kind of communication technology. Various wired and wireless communication technologies that are known in the art may be used, for example Ethernet, DMX, DALI, Bluetooth, Wi-Fi or ZigBee. A specific communication technology may be selected based on the communication capabilities of the processor 108, the type of lighting device 120, the type of wearable device 102, etc., the power consumption of the communication driver for the (wireless) communication technology and/or the communication range of the signals.

[0041] The wearable device 102 may be any suitable wearable device 102. The type of wearable device 102 (e.g. a bracelet, a ring, glasses, gloves, pendants, etc.) may be selected in relation to the context wherein the wearable device 102 will be used. The wearable device 102 comprises the detection unit 104 arranged for detecting contextual information of the wearable device 102 (e.g. the orientation, location, movement, etc.). The processor 108 of the system 100 further translates the contextual information detected by the detection unit 104 and determines the at least one installation characteristic (e.g. location, orientation, type of lighting device 120, etc.) of the lighting device 120 based on the contextual information. The wearable device 102 may further comprise a battery (not shown) for powering the different components of the wearable device 102.

[0042] The lighting device 120 may be arranged for emitting light. The lighting device 120 may comprise a light source arranged for emitting light. The lighting device 120 may be an LED bulb, an LED strip, a TLED, a Philips Hue lamp, an incandescent lamp, a fluorescent lamp, a high-intensity discharge lamp, etc. The lighting device 120 may be arranged for providing task lighting, ambient lighting, atmosphere lighting, accent lighting, etc. Alternatively, the lighting device may be arranged for controlling another lighting device. The lighting device 120 may be for example an occupancy sensor, an audio sensor, a vibration sensor, a motion sensor, etc.

[0043] In an embodiment, the detection unit 104 of the wearable device 102 is arranged for detecting an orientation of the wearable device 102 as the contextual information. The orientation of the wearable device 102 may be detected by an orientation sensor (e.g. a gyroscope, tilt sensor, magnetometer, etc.). Based on the information received from the orientation sensor, the processor 108 may determine the orientation of the lighting device 120 and determine whether the lighting device 120 is installed in a horizontal, vertical or diagonal position. This may allow the processor 108 to further determine whether the lighting device 120 is installed in/on a ceiling, in/on a wall or in/on a floor.

[0044] In an embodiment, the detection unit 104 of the wearable device 102 is arranged for detecting a movement of the wearable device 102 as the contextual information. The movement of the wearable device 102 may be detected by a motion sensor (e.g. an accelerometer). Based on the information received from the motion sensor, the processor 108 may determine the movement of the wearable device 102 and determine an installation characteristic of the lighting device 120 based on the movement. The movement may, for example, be a movement comprising a plurality of rotations, possibly indicating that the lighting device 120 is a light bulb (e.g. a Philips Hue bulb, a retrofit light bulb, etc.). In another example the movement may comprise: (1) a forward motion, (2) a 45 degree clockwise rotation with a sharp deceleration at the end and (3) a reverse motion. Combined with the information received from an orientation sensor, the processor 108 may, in this example, determine that the lighting device 120 is a tubular lighting device 120 (e.g. a fluorescent tube lamp, a TLED, etc.).

[0045] In an embodiment, the system 100 further comprises a positioning system. The positioning system may be for example an indoor positioning system that determines the location of an object based on radio waves, magnetic fields, acoustic signals, (coded) light signals or any other sensory information collected by the object. In this embodiment, the wearable device 102 is further arranged for receiving positional information from the positioning system. This allows the processor 108 to determine the location of the wearable device 102 during installation of the lighting device 120 and to, based on the location of the wearable device 102, determine the location of the lighting device 120. The processor 108 may further store the location of the lighting device 120 in the memory 110 as the installation characteristic. The processor 108 may be further arranged for determining the vertical location (i.e. the height) of the wearable device 102 (and therewith the vertical location of the lighting device 120) based on the received positional information.

[0046] In an embodiment, the detection unit 104 of the wearable device 102 is arranged for detecting the altitude of the wearable device 102. The altitude of the wearable device 102 may be detected by an altitude sensor (e.g. a (milli)barometric pressure sensor). Based on the information received from the altitude sensor, the processor 108 may determine the altitude of the wearable device 102 and determine an installation characteristic of the lighting device 120 based on the altitude. The information from the altitude sensor may be combined with the information from other sensors, for example information from the orientation sensor, thereby enabling the processor 108 to determine the altitude and the orientation of the lighting device 120. Thus, allowing the processor 108 to determine, for example, that a lighting device 120 is installed in a wall (based on the (horizontal) orientation of the wearable device 102) on eye level (based on the altitude of the wearable device 102). In another example, the altitude information may be combined with positional information from the positioning system. This may allow the processor 108 to determine that a lighting device 120 is installed in the ceiling (based on the altitude of the wearable device 102) and the processor 108 may further determine that the lighting device 120 is located, for example, in a corner of the room (based on the position of the wearable device 102).

[0047] In an embodiment, the detection unit 104 of the wearable device 102 is arranged for detecting sound. The sound may be detected by an audio sensor (e.g. a microphone). The audio sensor may detect sounds originating from the lighting device 120 or sounds generated when the lighting device 120 is physically connected to its socket (e.g. a clicking sound from a PoE luminaire with a RJ45 connector, or a unique sound of a screw/bayonet fitting). The physical connection of the lighting device 120 to its socket may generate a distinguishing sound signature that may be detected by the wearable device 102, which may allow the processor 108 to recognize a type of lighting device 120 based on the sound signature.

[0048] It should be noted that the above-mentioned embodiments are examples of installation characteristics that may be detected by the detection unit 104, and that those skilled in the art will be able to design many alternative examples of detection units 104 of the wearable device 102 for detecting many alternative types of installation characteristics, such as light level, distance from walls/ceiling/floor, temperature, moisture, time of day, weather conditions, etc.

[0049] The receiver 106 of the system 100 is arranged for receiving an identifier of the lighting device 120. The receiver 106 may be comprised in the wearable device 102 or in any other device (e.g. a smartphone, a hub, a laptop, etc.). The identifier may comprise a code generated by the lighting device 120, or the code may be generated by the processor 108 of the system 100. Additionally or alternatively, the identifier may comprise information about the type of lighting device 120 (e.g. that the lighting device 120 is an LED strip or an LED light bulb). Additionally or alternatively, the identifier may comprise a unique product identifier and/or comprise the serial number of the lighting device 120.

[0050] In an embodiment, the receiver 106 may be comprised in a smart phone that is connected to the lighting device 120 via, for example, Wi-Fi or Bluetooth. The receiver 106 may receive the identifier of the lighting device 120 from the lighting device 120 via for example a wireless (radio) signal, for example via Wi-Fi, Bluetooth, ZigBee, etc. The receiver 106 may further communicate the identifier of the lighting device 120 to the processor 108, which may also be comprised in the smart phone.

[0051] In an embodiment, the receiver 106 may be comprised in an intermediate communication device, for example a home automation system. The receiver 106 may receive the identifier of the lighting device 120 from the lighting device 120 via an electronic signal. The identifier may be received via a wired connection, for example via power-line communication. The receiver 106 may further communicate the identifier of the lighting device 120 to the processor 108 of the home automation system which stores the installation characteristic of the lighting device 120 linked to its identifier.

[0052] In an embodiment, the receiver 106 may be comprised in the wearable device 102. The receiver 106 may, for example, receive the identifier from the lighting device 120 via a coded light signal from the lighting device 120. The coded light may be visible or invisible. Upon installing the lighting device 120, the lighting device 120 may emit light comprising a code, the code comprising the identifier of the lighting device 120. The receiver 106 may, for example, comprise a light sensor and/or a camera arranged for detecting the light emission and for detecting the code. The receiver 106 may further communicate the identifier of the lighting device 120 to the processor 108, which may be comprised in the wearable device 102 or in a further device. Additionally or alternatively, the receiver 106 may receive the identifier from the lighting device 120 via a sound signal. The sound may be generated by the lighting device 120 or the sound may be generated when the lighting device 120 is physically connected to its socket. The physical connection of the lighting device 120 to its socket may generate a distinguishing sound signature that may be detected by receiver 106, thereby identifying the lighting device 120.

[0053] The processor 108 of the system 100 is arranged for determining at least one installation characteristic of the lighting device 120 based on the detected contextual information of the wearable device 102, and for linking the at least one installation characteristic to the identifier. The processor 108 may be comprised in the wearable device 102, or the processor 108 may be comprised in a further device (e.g. a smartphone, a hub, a laptop, etc.). The processor 108 is connected to the memory 110 and it may store, upon determining the installation characteristic of the lighting device 120 and upon receiving the identifier of the lighting device 120 from the receiver 106, the at least one installation characteristic and the identifier in the memory 110. The memory 110 may be located in the wearable device 102 or in a further device, for example in a home automation system or in the lighting device 120 itself. The home automation system may use the commissioning information of the system 100 for, for example, atmosphere creation (based on, for example, user preferences, user instructions or system commands).

[0054] In an embodiment of the system 100, the processor 108 is further arranged for activating and deactivating a commissioning mode of the wearable device 102. The commissioning mode is a mode of operation wherein the processor 108 is set to determine the at least one installation characteristic of the lighting device 120 based on the detected contextual information of the wearable device 102, and wherein the processor 108 is set to link the at least one installation characteristic to the identifier. The commissioning mode may be turned off and on in between the commissioning of two lighting devices 120, thereby allowing the system 100 to differentiate between lighting devices 120. The commissioning mode may be activated and or deactivated based on the contextual information of the wearable device 102 detected by the detection unit 104. For example, the commissioning mode may be activated upon detecting a distinguishing movement of the wearable device 102. The movement may be, for example, a rotational movement, indicating the installation of a light bulb. Another trigger that may be used to initialize the commissioning mode is a sound signal generated when the lighting device 120 is physically connected to its socket. The connection may generate a distinguishing sound signature that may be detected by the detection unit 104, whereupon the processor 108 may activate the commissioning mode. The commissioning mode may be deactivated based on different contextual information detected by the detection unit 104. For example, when a lighting device 120 is installed in the ceiling, a decrease in altitude of the wearable device 102 may be an indicator that a person is descending (for example from a ladder) and therefore may be finished installing the lighting device 120.

[0055] Additionally or alternatively, the commissioning mode may be activated or deactivated based on a user input. The system 100 may further comprise a user interface arranged for receiving the user input. The user interface may comprise a touch-sensitive device such as a touchpad or a touchscreen, an audio sensor such as a microphone, a motion sensor such as an accelerometer and/or a gyroscope for detecting gestures and/or one or more buttons for receiving the user input. The person commissioning the lighting device 120 may for example execute a first movement with the wearable device 102 that is indicative of the activation of the commissioning mode, while the execution of a second movement may be indicative of the deactivation. In other examples, the user may speak a voice command to activate/deactivate the commissioning mode, activate/deactivate the commissioning mode via the touchscreen of the user interface and/or press a button to activate/deactivate the commissioning mode. It should be noted that above-mentioned triggers for activation/deactivation of the commissioning mode are examples, and that those skilled in the art will be able to design many alternative examples of triggers for activation/deactivation of the commissioning mode.

[0056] FIG. 2 shows schematically an embodiment of a wearable device 200 according to the invention for commissioning a lighting device (not shown). The wearable device 200 comprises the detection unit 202 arranged for detecting contextual information of the wearable device 200. FIG. 2 shows a wrist worn wearable device 200, but the wearable device 200 may also be worn on the forearm, head, neck, hand, finger, etc. of a user installing the lighting device. Additionally, the wearable device 200 may further comprise the receiver 204 arranged for receiving the identifier from the lighting device. The receiver 204 may, for example, comprise a radio frequency (RF) receiver in order to receive an RF signal. The RF receiver may be arranged for transmitting an RF signal requesting an RF response signal comprising the identifier from the lighting device. Alternatively, the wearable device 200 may comprise an RF transceiver arranged for transmitting an RF signal and for receiving the transmitted RF signal after it has been backscattered by the RFID tag of the lighting device, enabling the wearable device 200 to identify the lighting device based on the backscattered signal. Additionally or alternatively, the wearable device 200 may comprise a light sensor or a camera arranged for receiving light emitted by the lighting device. The emitted light may comprise a code, the code comprising an identifier of the lighting device, which may be decoded by the processor, thereby identifying the lighting device.

[0057] In a further embodiment, the receiver 204 of the wearable device is further arranged for determining the proximity/distance of the lighting device. Various proximity/distance measuring methods that are known in the art may be used. Distance information can be acquired through for example measuring the received signal strength (RSS), wherein the distance is determined based on an RF signal backscattering from a receiving tag, or through time-of-flight (TOF), wherein the distance is determined based on the time between sending and receiving the RF signal. An advantage of determining the proximity/distance between the wearable device 200 and the lighting device is that the processor may determine the accuracy of the determination of at least one installation characteristic of the lighting device.

[0058] In an additional or alternative embodiment, the wearable device 200 may further comprise the processor 206 arranged for determining the at least one installation characteristic of the lighting device based on the detected contextual information of the wearable device 200, and for linking the at least one installation characteristic to the identifier. Additionally or alternatively, the wearable device 200 may further comprise the memory 208 arranged for storing the at least one installation characteristic and the identifier. Many consumer wearable devices are already equipped with a processing means, a communication means, a detection means and/or a memory, which may be advantageous because it may reduce the effort of creating a communication link between the different components of the system.

[0059] FIG. 3 shows schematically an embodiment of a wrist worn wearable device 300 according to the invention for commissioning a bulb lighting device 304. The detection unit 302 detects the orientation 306 and the movement 308 of the wearable device 300. The processor (not shown) may derive the orientation 306of the lighting device 304 from the orientation 306 of the wearable device 300 and determine that the orientation 306 of the wearable device 300 does not change while installing (screwing in) the lighting device 304. Furthermore, the processor (not shown) may derive the movement 308 of the lighting device 304 from the rotational movement 308 of the wearable device 300. The processor may further use the rotational movement 308 of the wearable device 300 (and therewith the movement 308 of the lighting device 304) and the non-changing orientation 306, 306 to determine that the type of lighting device 304 is a screwable lighting device.

[0060] FIG. 4 shows schematically an embodiment of a finger worn wearable device 400 according to the invention for commissioning a tube lighting device 404. The detection unit 402 detects the orientation 406 and the movement 406 of the wearable device 400. Upon installing the lighting device 404, the orientation 406 of the wearable device 400 changes while installing the lighting device. The change of orientation 406 and the half turn of the wearable device 400 may provide sufficient information for the processor (not shown) to determine that the lighting device 404 is a tube lighting device 404, for example a fluorescent tube or a TLED.

[0061] FIG. 5 shows schematically an embodiment of a system 500 according to the invention for commissioning lighting devices 504, 506 by a wearable device 502. The system 500 further comprises a positioning system 508a-d. FIG. 5 illustrates how the processor (which may be located in the wearable device 502, in the home automation terminal 510 or in any other device) may determine the installation characteristics based on the contextual information detected by the wearable commissioning device 502. In this embodiment, the positioning system 508a-d comprises a plurality of RF beacons 508a-d distributed throughout the room that communicate with the wearable device 502 and, based on the time-of-flight of the RF signals, the positioning system uses triangulation to determine the location of the wearable device 502. In this embodiment, the location, altitude and orientation are detected by the detection unit (not shown). The installation characteristics of a first lighting device 504 in FIG. 5 indicate that the lighting device 504 is located in the ceiling (based on the altitude from an altitude sensor of the wearable device 502 and the orientation from a direction sensor of the wearable device 502) and that it is located in the center of the room (based on the positioning information from the beacons 508a-d). The installation characteristics of a second lighting device 506 indicate that the lighting device 506 is installed in/on a wall (based on the altitude from an altitude sensor of the wearable device 502 and the orientation from a direction sensor of the wearable device 502) and that it is located at the side of the room (based on the positioning information from the beacons 508a-d). Upon completion of the commissioning of each lighting device 504, 506, the installation characteristics of the first 504 and second lighting device 506 may be stored in a memory located, for example, in the wearable device 502, the home automation terminal 510 (e.g. a pc that is arranged for controlling the lighting devices) or in the lighting devices 504, 506, whereafter the first 504 and second lighting device 506 are ready to be controlled.

[0062] FIG. 6 shows schematically and exemplary a method 600 of commissioning a lighting device 120 by a wearable device 102 when installing the lighting device 120. The method comprises the steps of:

[0063] receiving 602 an identifier of the lighting device 120,

[0064] detecting 604 contextual information of the wearable device 102, the contextual information being at least one of an orientation and/or a movement of the wearable device 102,

[0065] determining 606 at least one installation characteristic of the lighting device 120 based on the detected contextual information of the wearable device 102,

[0066] linking 608 the at least one installation characteristic to the identifier, and

[0067] storing 610 the at least one installation characteristic and the identifier. The step of receiving 602 an identifier of the lighting device 120 and the step of detecting 604 contextual information of the wearable device 102 are interchangeable and the order wherein these steps occur may depend on the specific embodiment. For example, installing a light bulb may require that the detection unit 104 of the wearable device 102 detects the rotational movement before the light bulb receives its power and may transmit its identifier. In a second example, the lighting device 120 may comprise an RF identification tag, which may be detected by the detection unit 104 of the wearable device 102 before the lighting device 120 in installed.

[0068] In an embodiment of the method 600, the method 600 further comprises the step of grouping a first lighting device with a second lighting device if the first lighting device and the second lighting device have a similar installation characteristic. This allows grouping, for example, ceiling lighting devices, or lighting devices that are located nearby each other. For example, an occupancy sensor may be grouped with luminaires in its vicinity. This embodiment further provides the advantage that sensing lighting device (such as an ultrasound motion detector) may be grouped with a light emitting lighting device (such as a light bulb). Furthermore, all lighting devices in a same room may be grouped in order to control all these lighting devices as one after commissioning.

[0069] It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims.

[0070] In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. Use of the verb comprise and its conjugations does not exclude the presence of elements or steps other than those stated in a claim. The article a or an preceding an element does not exclude the presence of a plurality of such elements. The invention may be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer or processing unit. In the device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
