Description

A method of configuring a lighting system

FIELD OF THE INVENTION

The invention relates to a lighting system. The invention further relates to a controller for configuring the lighting system. The invention further relates to a method of configuring a lighting system and to a computing program product for executing the method.

BACKGROUND

Current home lighting systems comprise a plurality of lighting devices. In various lighting systems, the plurality of lighting devices are connected to a central control device (e.g. a bridge, control hub, gateway, a smartphone, etc.), which is configured to receive input from and/or control the lighting devices via a wireless network. When a user adds a new lighting device to the lighting system, the new lighting device is added to the wireless network such that it can be operated. The user can then assign different functionalities to the lighting device for controlling the lighting device. For instance, the user may associate a sensor (e.g. a presence sensor or a switch or button) with the newly added lighting device, such that when the sensor is activated, the lighting device is controlled according to a certain light setting.

US 20160095188 Al discloses systems and methods for adjusting environmental conditions within a physical structure comprising a plurality of linked commissioned units. One or more occupancy sensors produce data indicating that a designated zone has transitioned from an unoccupied state to an occupied state. A first one or more luminaires associated with a first one of the plurality of linked commissioned units produces a background level of illumination within a predetermined reaction period following the production of the sensor data. The first one of the plurality of linked commissioned units transmits data indicative of the state change of the designated zone, and at least a second one of the plurality of linked commissioned units receives the data indicative of the state change, and causes at least a second one or more luminaires to alter illumination. SUMMARY OF THE INVENTION

The inventor has realized that certain lighting devices (which are to be added to a lighting system) may have preprogrammed lighting control rules. The new lighting device may, for example, comprise a light source and a sensor, and the lighting device may be preprogrammed such that the lighting device is controlled according to a (predefined) light setting when the sensor is activated. In current lighting systems, the user would have to add the new lighting device to the lighting system and set up control rules for the new lighting device and/or existing lighting devices of the lighting system. The inventor has realized that it may be beneficial to reduce effort of configuring a lighting system. It is therefore an object to improve the process of configuring a lighting system when a new lighting device is added.

According to a first aspect, the object is achieved by a lighting system comprising: a first lighting device comprising a first light source, a first controller configured to control the first light source, a first memory, and a second lighting device comprising: a second light source, a sensor configured to receive a sensor input indicative of an activation of the sensor, a second memory, a second controller configured to control the second light source based on the sensor input according to a lighting control rule stored in the second memory, and configured to communicate the lighting control rule to the first controller, wherein the first controller is configured to receive the lighting control rule from the second controller, to store the lighting control rule in the first memory and to configure the lighting system such that when the sensor or another sensor is activated, the first light source is controlled according to the lighting control rule.

The second lighting device may be a lighting device that is added to the lighting system by a user. The second lighting device comprises a second controller for controlling the second light source of the second lighting device according to a lighting control rule (e.g. a predefined (dynamic) light setting, a lighting control routine, etc.) when the sensor of the second lighting device is activated. The first controller (e.g. a lighting system controller) is configured to receive the lighting control rule and apply that to the first lighting device already present in the lighting system. The first controller is configured to configure the lighting system such that when the sensor or another sensor is activated, the first light source is controlled according to the lighting control rule. The other sensor is located in the same environment (e.g. room, area or building) as the first lighting device. As such, the control rule is copied from the second lighting device to the lighting system. Thus, when the sensor or the other sensor is activated, the first lighting device is controlled in a similar way as the second lighting device. This is beneficial, because it improves the process of configuring a lighting system when a new lighting device is added.

The first controller may be configured to receive a signal indicative of that the second lighting device has joined the lighting system, and the first controller is configured to configure the lighting system when the second lighting device has joined to the lighting system. The joining of the second lighting device may trigger the first controller of the lighting system to initiate the configuration of the lighting system. This is beneficial, because the behavior of the added lighting device is immediately copied to the lighting system.

The first controller may be configured to receive a user confirmation signal indicative of a confirmation from a user, and the controller may be configured to configure the lighting system only when the user confirmation signal has been received. This is beneficial, because the user can confirm whether the lighting system should be configured according to the lighting control rule.

The lighting control rule may define a light setting, and the second controller may be configured to control the second light source according to the light setting, and the first controller may be configured to configure the lighting system such that when the sensor or the other sensor is activated, the first light source is controlled according to the light setting.

Additionally or alternatively, the lighting control rule may define a lighting control routine, and the second controller may be configured to control the second light source according to the lighting control routine, and the first controller may be configured to configure the lighting system such that when the sensor or the other sensor is activated, the first light source is controlled according to the lighting control routine.

The lighting control routine may define a plurality of light settings for corresponding moments in time, and the second controller may be configured to control the second light source according to the light settings at the corresponding moments in time. The lighting control routine may, for example, be a wakeup routine, a go-to-sleep routine, circadian light scene, etc. of which the light settings change over a predefined period of time. This control rule may be stored in the second lighting device and copied to the first lighting device by the first controller. Consequently, the first lighting device also performs the lighting control routine.

The second lighting device may comprise a plurality of individually addressable second light sources. The plurality of individually addressable second light sources may be individually controllable by the second controller according to different light settings. The lighting control rule may define a plurality of light settings for the plurality of individually addressable second light sources. The second controller may be configured to control the plurality of individually addressable second light sources according to the plurality of light settings. The lighting system may comprise a plurality of first lighting devices, and the first controller may be configured to configure the lighting system such that when the sensor or the other sensor is activated, the plurality of first lighting devices are controlled according to at least two of the plurality of light settings. This is beneficial because the plurality of first lighting devices are controlled according to the same light settings as the individual light sources of the second lighting device.

The first controller may be configured to configure the lighting system such that when the sensor or the other sensor is activated, both the first and the second light source are controlled according to the lighting control rule simultaneously. This further integrates the second lighting device into the lighting system, and the user can activate the lighting control rule for multiple lighting devices by activating the sensor.

The sensor may be a presence sensor, and the sensor input may be indicative of a presence of a user activating the presence sensor. The sensor may be a camera, a PIR sensor, etc. Alternatively, sensor may be a user input element (e.g. a switch, a rotary button, etc.), and the sensor input may be an activation of the user input element by a user.

The other sensor may be of the same sensor type as the sensor. The first controller may be configured to determine if the type of the other sensor is of the same type as the sensor of the second lighting device, and to configure the lighting system according to the control rule only if the other sensor is of the same sensor type as the sensor.

According to a second aspect, the object is achieved by a controller according to the first controller of any of the preceding claims for configuring the lighting system of any of the preceding claims.

According to a third aspect, the object is achieved by a method of configuring a lighting system, the lighting system comprising a first lighting device comprising a first light source, a first controller configured to control the first light source, a first memory, and a second lighting device comprising a second light source, a sensor configured to receive a sensor input indicative of an activation of the sensor, a second memory, and a second controller configured to control the second light source based on the sensor input according to a lighting control rule stored in the second memory, the method comprising: communicating, by the second controller, the lighting control rule to the first controller, receiving, by the first controller, the lighting control rule from the second controller, storing the lighting control rule in the first memory, and configuring the lighting system such that when the sensor or another sensor is activated, the first light source is controlled according to the lighting control rule.

It should be understood that the controller, method and computer program product may have similar and/or identical embodiments and advantages as the above-mentioned lighting system.

DETAILED DESCRIPTION

Fig. 1 shows schematically a lighting system 100 comprising a first lighting device 110 and a second lighting device 120. The lighting system 100 further comprises a (first) controller 102 for configuring the lighting system 100. In the example of Fig. 1, the first lighting device 110 comprises a first light source 112, a communication unit 114 and a processing unit 116 for controlling the first light source 112. The processing unit 116 (e.g. a microprocessor, circuitry, a microchip, etc.) is configured to receive lighting control commands from a lighting control device (e.g. (first) controller 102) via the communication unit 114 (e.g. via Zigbee, Bluetooth, Wi-Fi, 4G, Ethernet, etc.), and control the first light source 112 based on the lighting control commands. The lighting control commands may comprise control instructions for controlling the light source 114 according to a light setting (e.g. a lighting control value indicative of the color, brightness, saturation, beam size/angle, etc.). The first lighting device may further comprise a memory 118 and a sensor 130, which will be discussed further below.

In the example of Fig. 1, the second lighting device 120 comprises a second light source 122, a communication unit 124 and a processing unit 126 (i.e. the second controller 126) (e.g. a microprocessor, circuitry, a microchip, etc.) for controlling the second light source 122. The processing unit 126 is configured to control the light source 122 based on lighting control commands. The lighting control commands may comprise control instructions for controlling the light source 122 according to a light setting (e.g. a lighting control value indicative of the color, brightness, saturation, beam size/angle, etc.). The second lighting device 120 further comprises a second memory 128 and a sensor 140. The second controller 126 is configured to control the second light source 122 based on a sensor input from the sensor 140 according to a lighting control rule stored in the second memory 128. The lighting control rule may define a light setting that is to be activated when the sensor is activated/triggered (e.g. by a user).

The second controller 126 is further configured to communicate the lighting control rule to the first controller 102 (e.g. a microprocessor, circuitry, a microchip, etc.) via the communication unit 124. In the example of Fig. 1, the first controller 102 comprises a processing unit 106, a first memory 108 and a communication unit 104 for communicating with the first and second lighting devices 110, 120. In the example of Fig. 1, the first controller 102 is located in a separate lighting control device (e.g. a bridge, a mobile device, a cloud server, etc.). It should be understood that Fig. 1 is merely an example of a system architecture, and that the skilled person is able to design alternative locations of the first controller (e.g. in the first lighting device 110, or in another lighting device) dependent on the system architecture.

The first controller 102 (e.g. processing unit 106) is configured to receive the lighting control rule from the second controller 126, to store the lighting control rule in the first memory 108 and to configure the lighting system 100 such that when the sensor 140 or another sensor (e.g. sensor 130, or sensor 150) is activated, the first light source 112 is controlled (e.g. by processor 116) according to the lighting control rule. The first controller 102 may, for example, associate a sensor activation of the sensor or the other sensor with controlling the first light source 112 of the first lighting device 110. For instance, the first controller 102 may configure the lighting system 100 such that when the sensor 140 or another sensor 130, 150 is activated (triggered), it may send a lighting control command to lighting device 110 (e.g. directly or via a lighting control device such as the first controller 102). The lighting control command may, for example, comprise a light setting and the processing unit 116 of the lighting device may control the light source 112 accordingly. Alternatively, an association between a light setting and a sensor signal may be stored in memory 118 of the first lighting device 110, and the processing unit 116 of the first lighting device 110 may retrieve the associated light setting from the memory 118 when the lighting control command from the sensor 140 or the other sensor 130, 150 is received.

The second memory 128 may be configured to store a plurality of lighting control rules, and the second controller 126 may be configured to communicate the plurality of control rules to the first controller 102 via the communication unit 124. The first controller 102 may be configured to store the plurality of lighting control rules in the first memory 108 and to configure the lighting system 100 based on these lighting control rules. In first example, a first control rule may define a first association between a first light setting and a first time of day (e.g. a first time period), and a second control rule may define a second association between a second light setting and a second time of day (e.g. a second time period), the second controller 126 of the second lighting device 120 may be configured to control the second light source 122 according to the first light setting if the sensor 140 is activated at the first time of day, and to control the second light source 122 according to the second light setting if the sensor 140 is activated at the second time of day. The first and second lighting control rules may be communicated to the first controller 102, which may apply these rules such that when the sensor 140 or the other sensor 130, 150 is activated at the first time of day, the first light source 112 of the first lighting device 110 is controlled according to the first light setting, and such that when the sensor 140 or the other sensor 130, 150 is activated at the second time of day, the first light source 112 of the first lighting device 110 is controlled according to the second light setting.

The first controller 102 may be configured to configure the lighting system 100 such that when the sensor 140 or the other sensor 130, 150 is activated, both the first and the second light source 112, 122 are controlled according to the lighting control rule simultaneously.

The other sensor 130, 150, may be a sensor 130 comprised in the first lighting device 110, or be a sensor 150 comprised in a sensor device. The location of the other sensor may be dependent on the system configuration of the lighting system 100, and may be selectable by a user.

The type of the other sensor 130, 150 may be of the same type as the sensor 140. The first controller 102 may be configured to determine if the type of the other sensor 130, 150 is of the same type as the sensor 140 of the second lighting device 120, and configure the lighting system 100 according to the control rule only if the other sensor 130, 150 is of the same sensor type as the sensor 140. Additionally or alternatively, the lighting system 100 may comprise a plurality of other sensors, and the first controller 102 may be configured to select a sensor (as the other sensor 130, 150) which has a sensor type that corresponds to the type of the sensor 140 of the second lighting device 120. For instance, if the lighting system 100 comprises a motion sensor and a light switch, and the sensor 140 is a switch of the second lighting device 120, the first controller 102 may select the motion sensor (as the other sensor) and configure the first lighting device 110 according to the control rule.

The sensor 140 of the second lighting device 120 may be any type of sensor configured to provide a sensor signal to the second controller 126 to activate the second light source. The sensor 140 may, for example, be a presence sensor (e.g. a camera, a motion sensor, etc.). Alternatively, the sensor 140 may be a user input element and the sensor input is an activation of the user input element by a user. The user input element may for example be a light switch (e.g. a button, a touch-sensitive element, a rotary switch, etc.). Alternatively, the sensor 140 may be an environmental sensor (e.g. a temperature sensor, a daylight sensor, etc.). Figs. 2a-2c show schematically examples of second lighting devices 120a, 120b, 120c comprising respective light sources 122a, 122b, 122c and respective sensors 140a, 140b, 140c.

In the example of Fig. 2a, the second lighting device 120a is a flood lighting device and the sensor 140a is a presence sensor (e.g. a camera, a motion sensor, etc.). The second lighting device 120a may be configured according to a lighting control rule such that when presence is detected, the light source 122a is switched on (e.g. to full brightness). The first controller (not shown) may receive this control rule from the second lighting device 120a, and configure the lighting system 100 such that when the sensor 140a or another sensor is activated, the first lighting device (located in the same area) is also switched on (e.g. to full brightness).

The second lighting device may comprise a plurality of individually addressable second light sources. The plurality of individually addressable second light sources are individually controllable by the second controller 126 according to different light settings. The lighting control rule may define a plurality of light settings for the plurality of individually addressable second light sources. The second controller 126 may be configured to control the plurality of individually addressable second light sources according to the plurality of light settings. The lighting system 100 may comprise a plurality of first lighting devices, and the first controller 102 may be configured to configure the lighting system such that when the sensor or the other sensor is activated, the plurality of first lighting devices are controlled according to at least two of the plurality of light settings. An example thereof is illustrated in Fig. 2b. In the example of Fig. 2b, the second lighting device 120b is a pixelated lighting device and the sensor 140b is a switch. The second lighting device 120b may be configured according to a lighting control rule such that when a user presses the switch, the light sources 122b are controlled according to a gradient pattern (e.g. a color gradient across the plurality of light sources 122b, which color gradient may be defined by a color palette). The first controller (not shown) may receive this control rule from the second lighting device 120b, and configure the lighting system 100 such that when the sensor 140b or another sensor is activated, the first lighting device (located in the same area) is controlled in a similar way. The first lighting device may also comprise a plurality of light sources which may be controlled according to the gradient pattern and/or according to the color palette. In a further example, the lighting system may comprise a plurality of first lighting devices, and the first controller may be configured to configure the lighting system 100 such that when the sensor 140b or another sensor is activated, the plurality of first lighting devices are controlled in a similar way, for instance according to the gradient pattern (e.g. based on the locations of the plurality of first lighting devices) or according to the color palette.

In the example of Fig. 2c, the second lighting device 120c is a ceiling luminaire and the sensor 140b is a PIR sensor. The second lighting device 120c may be configured according to a lighting control rule such that when a user activates the PIR sensor, the light sources 122c are controlled according to a first light setting (e.g. full brightness) and to a second setting (e.g. 50% brightness) after a certain period of time if no sensor signal from the PIR sensor has been received. The first controller (not shown) may receive this control rule from the second lighting device 120c, and configure the lighting system 100 such that when the sensor 140c or another sensor is activated, the first lighting device (located in the same area) is controlled in a similar way (e.g. according to a first light setting (e.g. full brightness) and to a second setting (e.g. 50% brightness) after a certain period of time if no sensor signal from the PIR sensor or the other sensor has been received).

The first controller 102 may be configured to receive a signal indicative of that the second lighting device 120 has joined the lighting system 100 (e.g. the (wireless) network of the lighting system 100). The first controller 120 may be configured to configure the lighting system when the second lighting device 120 has joined to the lighting system 100. Additionally or alternatively, the first controller 102 may be configured to receive a user confirmation signal indicative of a confirmation from a user, and configure the lighting system 100 according to the lighting control rule only when the user confirmation signal has been received. The signal may be received from a user interface device (e.g. a home assistant, a central lighting control panel, a mobile device comprising a touch-sensitive display, a voice interface, a touch/press interface (button), etc.), which enables the user to confirm that the control rule is to be applied to the lighting system 100.

The first controller 102 may be configured to obtain location data indicative of the location of the second lighting device 120 and the locations of one or more first lighting devices. The locations may be obtained from an (indoor) positioning system, from a (central) lighting control system storing locations of lighting devices, etc. Systems and techniques for providing locations of lighting devices are known in the art and will not be discussed in detail. The first controller 102 may be configured to select the first lighting device 110 based on the respective locations of the first and second lighting devices. The first controller 102 may for example select a first lighting device 110 located within a predefined proximity of the second lighting device 120 or select a first lighting device 110 located in the same room as the second lighting device 120. The second lighting device 120 may, for example, be added to a room in a building when it is added to the lighting system 100, and the first controller 102 may be configured to select a first lighting device 110 located in that room from the plurality of first lighting devices. The second lighting device 120 may, for example, be added to the room in the building by a user via a user interface (e.g. a touch-sensitive display of a mobile device), and the first controller 102 may be configured to select the first lighting device 110 located in that room.

Additionally or alternatively, the first controller 102 may be configured to obtain location data indicative of the location of the second lighting device 120 (and/or the first lighting device 110) and the locations of one or more other sensors 150. The locations may be obtained from an (indoor) positioning system, from a (central) lighting control system storing locations of lighting devices and sensors, etc. Systems and techniques for providing locations of lighting devices and sensors are known in the art and will not be discussed in detail. The first controller 102 may be configured to select the other sensor 150 based on the respective locations of the other sensor 150 and second lighting device 120 (and/or the first lighting device 110). The first controller 102 may for example select a sensor 150 located within a predefined proximity of the second lighting device 120 (and/or the first lighting device 110) or select a sensor 150 located in the same room as the second lighting device 120 (and/or the first lighting device 110). The second lighting device 120 may, for example, be added to a room in a building when it is added to the lighting system 100, and the first controller 102 may be configured to select a sensor 150 located in that room.

The lighting control rule may define a light setting (e.g. lighting control values indicative of the color, brightness, saturation, beam size/angle, etc.). The second controller 126 may be configured to control the second light source 122 according to the light setting when the sensor 140 is activated. The first controller 102 may be configured to configure the lighting system 100 such that when the sensor 140 or another sensor 130, 150 is activated, the first light source 112 of the first lighting device 110 is controlled according to that light setting. Additionally or alternatively, the lighting control rule may define a lighting control routine (e.g. lighting control values that change over time or are defined for predefined period(s) of time). The second controller 126 may be configured to control the second light source 122 according to the lighting control routine when the sensor 140 is activated. The first controller 102 may be configured to configure the lighting system 100 such that when the sensor 140 or another sensor 130, 150 is activated, the first light source 112 of the first lighting device 110 is controlled according to that lighting control routine. Examples of lighting control routines include but are not limited to wake-up/go-to-sleep lighting routines, circadian lighting routines, presence-based lighting control routines and energy saving lighting control routines. The lighting control routine may define a plurality of light settings for corresponding moments in time (e.g. times and/or periods of the day).

Fig. 3 shows schematically a method of configuring a lighting system according to the lighting system described above. The method comprises: communicating 302, by the second controller, the lighting control rule to the first controller, receiving 304, by the first controller, the lighting control rule from the second controller, storing 306 the lighting control rule in the first memory, and configuring 308 the lighting system such that when the sensor or another sensor is activated, the first light source is controlled according to the lighting control rule.

The method 300 may be executed by computer program code of a computer program product when the computer program product is run on a processing unit of a computing device, such as the first and second controllers 102 and 126 of the lighting system 100.
