The present application is generally related to lighting systems. In particular, the present application is directed to systems and methods for assigning a status to a lighting device within a network of lighting devices.
Lighting systems are used in a variety of settings and applications. Many lighting systems traditionally comprise light sources or lighting devices having only limited control and functionality. Such lighting systems are often controlled only by on and off switches or switches that may control the level of lighting. Furthermore, one lighting device may be connected to another lighting device via simple connections between them. A traditional lighting system may include a group of lighting devices connected to the same power or intensity control but without intelligence to control behavior between them. Some intelligent lighting systems do offer more control but are often more expensive due to their complexity in design and increased number of components.
The present disclosure presents a relatively inexpensive yet intelligent solution for assigning a status to a lighting device over a connection used for transmissions of power and/or intensity for the lighting device.

In some embodiments, light source 110B, having a master status, transmits a first information using data bits 215 or instruction bits 220 to light source 110A which has a slave status. Light source 110A receives the first information and in response to the first information adjusts the status of the light source 110A to a master status. Light source 110A, having a master status, transmits a second information using data bits 215 or instruction bits 220 to the light source 110B. Light source 110B receives the second information and in response to the second information adjusts the status of the first light source 110B to a slave status. In a number of embodiments, light source 110A, having a master status, transmits a third information via data bits 215 or instruction bits 220 to a plurality of lighting system components, one of which is light source 110B. The third information transmitted by light source 110A comprises address 127B. The plurality of lighting system components receive the third information and light source 110B receives the third information. Light source 110B matches address 127B within the third information to address 127B of the light source 110B. In some embodiments, light source 110B, in response to the third information, adjusts the status of light source 110B to a status of a master. In a number of embodiments, light source 110B, in response to the address 127B matching the address 127B of the light source 110B, adjusts the status of light source 110B to a status of a master. In a plurality of embodiments, light source 110B, in response to the received third information and in response to the address 127B matching the address 127B of the light source 110B, adjusts the status of light source 110B to a status of a master.
In some embodiments, a plurality of light sources 110, each having a status of a master or a slave, communicate using a same connection 105 component, such as a wire or an electrical current conducting line. In such embodiments, any of the light sources 110 may become a master or a slave. Sometimes, the plurality of light sources 110 communicating over a same connection 105 component include only a single master, while all other light sources 110 have a status of a slave. In such embodiments, one of the light sources 110 having a status of a slave pulls the voltage potential within the connection 105 component low for a period of time, such as a microsecond, a millisecond or a second. The light source 110 having a status of a master interprets the low voltage signal in the connection 105 component as a signal to change status from master to slave. The light source 110 having a status of a master accepts the status of a slave, and the light source 110 which pulled the voltage potential low accepts the status of a master. Thus the signal across the connection 105 component signals a change in the status of one or more light sources 110 communicating over the same connection 105 component. In some embodiments, the signal that changes the status of one or more lighting system components may be a high voltage potential signal, a low voltage signal, an impulse, a digital pattern, a ground signal, or any other analog or digital signal transmitted over connection 105.
In a number of embodiments, when a group of light sources 110 are all off, upon being turned on, each one of the group of light sources 110 turns on with a status of a master. In some embodiments, upon receiving a signal that a light source 110 having a master status, also called a master, already exists, a light source that has just turned on changes its own status to a status of a slave. Thus, when a group of light sources 110 are all turned on at once it is ensured that at least one master exists. In some embodiments, light source 110 upon turning on and automatically changing its own status to a master, the light source 110 listens for a period of time if there is another master on the network. If the light source 110 does not receive any messages that there is another master on the network, the light source 110 remains the master.

Vicinity is, herein, defined as any amount of distance or any distance range. In some embodiments, vicinity is a distance of 5 or 10 centimeters. In other embodiments, vicinity is a range of a distance of 10 centimeters to 10 meters. In a plurality of embodiments, vicinity is a range of a distance of 1 millimeter to 30 centimeters. In many embodiments, vicinity is a range of distance which varies through time. In a plurality of embodiments, vicinity is a range of distance which is constant and predetermined for a specific light switch enclosure 400.
In a number of embodiments, LED 405 emits light having pulses occurring at a specific frequency and a specific light intensity which, in combination, are at the detection threshold point of light detector 420. In various embodiments, LED 405 emits light having pulses occurring at a frequency and each of the pulses having a duty cycle which, in combination, are at the detection threshold point of light detector 420. Sometimes, changing either the frequency of the pulses or the duty cycle of the pulses makes the optical signal emitted by LED 405 detectable or not detectable by the light detector 420. In many embodiments, LED 405 emits light at pulses of specific frequency, at a specific intensity and within a specific wavelength range, which in combination, produce a light signal which is at the detection threshold point of light detector 420. Detection threshold any combination pulse frequency, light intensity per pulse and a wavelength range of light signal emitted by LED 405 which borders the range of light signals detectable by light detector 420 and the range of light signals not detectable by light detector 420. In a plurality of embodiments, detection threshold is a setting of any of pulse frequency, light intensity or wavelength range of light emitted by LED 405 below which light detector 420 does not detect the light emitted and above which light detector 420 detects the light emitted. In some embodiments, a lighting system component within the light switch enclosure 400 comprises any one of or a combination of a circuit, a unit, an algorithm or a function which adjusts the detection threshold point in response to the background infrared radiation or signal.
Sometimes, light switch enclosure 400 comprises an LED 405 emitting an infrared optical signal at a constant pulse frequency of between 20 and 50 kilohertz. Sometimes, the infrared optical signal has a constant wavelength or a wavelength range. In some embodiments, the infrared optical signal has a duty cycle for each pulse which is optimized to bring the light switch enclosure 400 at a detection threshold point. In some embodiments, making a duty cycle shorter makes the infrared optical signal detectable by the light detector 420. In some embodiments, making a duty cycle longer makes the infrared optical signal detectable by the light detector 420. In a plurality of embodiments, a duty cycle of the infrared optical signal is set so the light detector 420 cannot detect the optical signal unless object 450 is in the vicinity of the light switch 400 enclosure. Upon bringing the object 450 in the vicinity of the light switch 400 enclosure, in such embodiments, the object 450 affects the light detected by the light detector 420, and the light detector 420 detects the light emitted by LED 405.
Sometimes, light switch enclosure 400 may comprise a plurality of LEDs 405. In a number of embodiments, a light switch enclosure 400 comprises two LEDs 405. In some embodiments, a first LED 405 emits a pulsed signal for light detector 420 as described above. In some embodiments, the a second LED 405 emits a constant low intensity light, such as an infrared signal of the intensity similar to the intensity of a background noise. Sometimes, lighting system 100 background environment creates background noise, such as infrared noise crated by lights, or heat sources. In a number of embodiments, the light emitted by the second LED 405 has a higher intensity than the background noise. In many embodiments, the second LED 405 creates a synthetic background radiation of a higher intensity than the background noise. In some embodiments, a second LED 405 emits a constant low intensity light which is lower than the intensity of pulses emitted by a first LED 405 but higher intensity than the background noise. The second LED 405, in some embodiments, emits a constant light of higher intensity than the intensity of background noise, thus decreasing the effect of the background noise on the light detector 420 or the light switch enclosure 400. The first LED 405, in such embodiments, is used to emit pulsed light signal which the light detector 420 detects when object 450 is in the vicinity.
In some embodiments, detection threshold point is dependent on wavelength of light received by light detector 420. In a number of embodiments, detection threshold point is dependent on frequency of pulses of light received by light detector 420. In a plurality of embodiments, detection threshold point is dependent on light intensity of each of pulses of light received by light detector 420. In many embodiments, detection threshold point is dependent on any combination of wavelength or wavelength range, pulse frequency or intensity of light received by light detector 420. In a plurality of embodiments, detection threshold point depends on distance, relative position, relative angles or sizes and shapes of LED 405 and light detector 420. In many embodiments, detection threshold point is found by tuning, adjusting or modifying each light switch enclosure 400 using object 450 to find the detection threshold point. In some embodiments, detection threshold point is found by tuning, adjusting or modifying pulse frequency of pulses of light emitted by LED 405. In a number of embodiments, detection threshold point is determined by tuning, adjusting or modifying wavelength range of light emitted by LED 405. In many embodiments, detection threshold point is determined by tuning, adjusting or modifying intensity of light emitted by LED 405.
In a number of embodiments, object 450 is positioned within in a vicinity of, or within a specific distance from, light switch enclosure 400 to help determine a new detection threshold point. In many embodiments, object 450 is a user's hand placed in vicinity of, or within a specific distance from, the light switch enclosure, resulting in a light source 110, or a plurality of light sources 110, being turned on. In some embodiments, object 450 is placed within the vicinity of, or within specific distance from, the light switch enclosure, resulting in a light source 110, or a plurality of light sources 110, being turned off. In some embodiments, the distance of the object 450 from the light switch enclosure 400 is directly or indirectly proportional to the intensity of one or more light sources 100 to be emitted. In some embodiments, the distance of the object 450 from the light switch enclosure 400 is inversely proportional to the intensity of one or more light sources 100 to be emitted. In a number of embodiments, the user controls the intensity of light emitted by one or more light sources 110 by controlling the distance between the object 450 and light switch enclosure 400.
In a plurality of embodiments, object 450 is placed within a predetermined distance of a light switch enclosure 400 and light detector 420, in response to the placement of object 450, detects light emitted by LED 405.

In many embodiments, object 450 is placed within a predetermined distance of a light switch enclosure 400, and light detector 420, in response to the placement of object 450, detects light emitted by LED 405 and lighting system 100 turns one or more light sources 110 on. In numerous embodiments, object 450 is placed within a predetermined distance of a light switch enclosure 400, and light detector 420, in response to the light reflected by the object 450, detects light emitted by LED 405 and lighting system 100 turns one or more light sources 110 on. In a number of embodiments, object 450 emits an optical signal or a light toward a light switch enclosure 400, and light detector 420, in response to the received optical signal or the light emitted by the object 450, detects light emitted by LED 405 and lighting system 100 turns one or more light sources 110 on.
Lighting system 100, in some embodiments, comprises a plurality of lighting system 100 components. Some of the lighting system 100 components may be associated with one or more light switch enclosures comprising an LED 405 and a light detector 420. In some embodiments, each lighting system 100 component comprises, or is associated with, a light switch enclosure 400. In some embodiments, lighting system 100 comprises a plurality of light sources 110 connected in series, each light source comprising or being associated with a light switch enclosure 400.
Sometimes, light switch enclosures 400 may be used for assignment of unique digital addresses for a plurality lighting system 100 components. In a number of embodiments, a plurality of light sources 110, each comprising a light switch enclosure 400, are assigned unique digital addresses, such as addresses 127. In many embodiments, a plurality of light sources 110 connected in series and each comprising a light switch enclosure 400, are assigned unique digital addresses to be used for communication.
A component of a lighting system 100 component having a master status, which is sometimes also referred to as the master, is placed into an assignment mode. An assignment mode, in some embodiments, is a mode, a function, a feature or a capability of a lighting system 100 to assign addresses 127 to any lighting system 100 component. An assignment mode, in other embodiments, is a mode, a function, a feature or a capability of a lighting system 100 component to assign addresses 127 to any lighting system 100 component. In numerous embodiments, an assignment mode is a function or a setting of any of the lighting system 100 components. In some embodiments, assignment mode is a mode, a function, a feature or a capability implemented by any of a controller 120, a communicator 125, a master/slave addressor 130, a power supply 140 or a light source 110. Assignment mode, in some embodiments, comprises a software, a hardware or a combination of software and hardware for implementing tasks relating to assignment of addresses 127 for each of the lighting system 100 components.
In a number of embodiments, assignment mode comprises a plurality of addresses 127 and means for communicating one of the plurality of addresses 127 to each component to be associated with the address 127. Assignment mode, in a number of embodiments, comprises means for transmitting or receiving confirmation messages from each of the lighting system 100 components who have received and accepted the addresses 127. In many embodiments, lighting system 100 components, store the address 127 received from the master and transmit a confirmation message to the master, confirming that they have accepted the address 127 assigned. In some embodiments, the master transmits one of a plurality of addresses 127 to each of the lighting system 100 components and waits for the lighting system 100 components to accept the address 127 transmitted. The lighting system 100 component accepts the address 127 and returns to the master the confirmation message indicating that the lighting system component has accepted the address 127. The master stores the address 127 and associates it with lighting system 100 component and uses it for any communication to the lighting system 100 component in the future. For example, light source 110A accepting address 127A previously sent by the master sends a confirmation message confirming that light source 110A component has accepted the address 127. The master, in response to the received confirmation message, associates address 127 with the lighting system 100 component for any future communication. In some embodiments, assignment mode entails the master receiving messages from one or more lighting system 100 components and assigning addresses 127 in response to the received messages.
In some embodiments, light switch enclosures 400 are associated with lighting system 100 components and are used for assignment of addresses 127. In some embodiments, a master communicates with a plurality of lighting system 100 components which may or may not have a master status. One of the plurality of lighting system 100 components is a light source 110A. In a number of embodiments, lighting system 100 components send information to the master using light switch enclosures 400 associated with lighting system 100 components. A master is placed in an assignment mode and is available to receive any information from any one or more of lighting system 100 components. A user may select a light source 110A by placing an object 450, such as a hand, in front of a light switch enclosure 400 associated with the light source 110A. Light detector 420 of the light switch enclosure 400, in response to the placed object 450, detects light emitted by LED 405 and light switch enclosure 400 sends a signal indicating that the light source 110A is selected. Light source 110A transmits a signal to the master indicating the user's selection and the master assigns an address 127, such as address 127A, to light source 110A. The master transmits information notifying light source 110A of the new address 127 assigned to the light source 110A. The light source 110A uses the assigned address 127 to receive for communication with master or any other lighting system 100 component. In some embodiments, light source 110A uses the assigned address 127 to recognize which information transmitted by any other lighting system 100 component is addressed to light source 110A.
Similarly, the user proceeds to select any number of lighting system 100 components by placing an object 450 in front of light switch enclosure 400 associated of each selected lighting system 100 component. The master, in response to user's selections, assigns an address 127 to each of the user selected lighting 100 system components. Upon completing all the selections, the user terminates the assignment mode and the master stores all the addresses 127 and lighting system 100 components associated with each of the addresses 127. The lighting system 100 components use addresses 127 assigned to transmit or receive information or communication among the lighting system 100 components assigned. In some embodiments, this method is used to create a group of lighting system 100 components, or a group of light sources 100. In many embodiments, this method is used to distinguish a group of lighting system 100 components or light sources 110 from other lighting system 100 components or light sources 110. In a number of embodiments, each of the groups created or distinguished are controlled separately.
In some embodiments, each lighting system 100 component uses a non-volatile memory for storing addresses 127 of one or more lighting system 100 components. Sometimes, one or more addresses 127 of one or more lighting system components belonging to a group or a zone are stored in a non-volatile memory of a lighting system component controlling the group or the zone. In a number of embodiments, address 127 of each lighting system 100 component may comprise a group identifier, uniquely identifying a zone or a group the lighting system 100 component is a part of. In a plurality of embodiments, lighting system 100 controls one or more light sources 110 having a same group identifier by sending one information or an instruction to every member of the group or the zone. In many embodiments, a group identifier is an address 127. In some embodiments, a group identifier is a part of an address 127. In a plurality of embodiments, a group identifier comprises an address 127. In a number of embodiments, a group identifier is an identifier separate from an address 127.
Sometimes, a user assigns a group identifier to one or more light sources 110 using a light switch enclosure 400 by placing an object 450 in the vicinity of, or on top of, the light switch enclosure 400 of the one or more light sources 110. In some embodiments, a user assigns a group identifier to each of a plurality of light sources 110 using a lighting system 100 component for receiving responses from one or more light sources 110. The user picks each individual light source 110 by placing an object 450 in the vicinity of, or on top of, the light switch enclosure 400 of each one of the plurality of light sources 110. The lighting system 100 component receives responses from the each one of the plurality of light sources 110 and assigns the group identifier to each of the light sources 110 that have responded. Sometimes, the mode wherein the light system 100 or a lighting system 100 component assigns group identifiers is called a learn ID mode. The learn ID mode ends when all the light sources 110 which were picked by the user send their responses to a lighting system 100 component in charge of storing or controlling the group. The lighting system 100 or a lighting system 100 component controlling the group then knows which light sources 110 are part of the group, and is able to communicate with the group using the assigned group identifier.
