- dedicated computer-controllable light fixtures including conventional space-illumination light sources and LED-based light fixtures, as well as combined fixtures, may be distributed throughout a space and coupled together as a network to facilitate computer control of the fixtures.

More specifically, according to one embodiment, individual light sources or groups of light sources are coupled to independently controllable output ports of one or more controllers, and a number of such controllers may in turn be coupled together in various configurations to form a networked lighting system. According to one aspect of this embodiment, each controller coupled to form the networked lighting system is "independently addressable,” in that it may receive data for multiple controllers coupled to the network, but selectively responds to data intended for one or more light sources coupled to it.
- individually light sources or groups of light sources coupled to the same controller or to different controllers may be controlled independently of one another based on various control information (e.g., data) transported throughout the network.
- control information e.g., data
- one or more other controllable devices e.g., various actuators, such as relays, switches, motors, etc.
- various actuators such as relays, switches, motors, etc.
- output ports of one or more controllers also may be coupled to output ports of one or more controllers and independently controlled.
- a networked lighting system may be an essentially one-way system, in that data is transmitted to one or more independently addressable controllers to control various light sources and/or other devices via one or more output ports of the controllers.
- controllers also may have one or more independently identifiable input ports to receive information (e.g., from an output of a sensor) that may be accessed via the network and used for various control purposes.
- the networked lighting system may be considered as a two-way system, in that data is both transmitted to and received from one or more independently addressable controllers. It should be appreciated, however, that depending on a given network topology (i.e., interconnection of multiple controllers) as discussed further below, according to one embodiment, a controller may both transmit and receive data on the network regardless of the particular configuration of its ports.
- a lighting system controller may include one or more independently controllable output ports to provide control signals to light sources or other devices, based on data received by the controller.
- the controller output ports are independently controllable in that each controller receiving data on a network selectively responds to and appropriately routes particular portions of the data intended for that controller's output ports.
- a lighting system controller also may include one or more independently identifiable input ports to receive output signals from various sensors (e.g., light sensors, sound or pressure sensors, heat sensors, motion sensors); the input ports are independently identifiable in that the information obtained from these ports may be encoded by the controller as particularly identifiable data on the network.
- the controller is "independently addressable,” in that the controller may receive data intended for multiple controllers coupled to the network, but selectively exchanges data with (i.e., receives data from and/or transmits data to) the network based on the one or more input and/or output ports it supports.

- a network of multiple controllers may not include a central hub processor exchanging information with the controllers; rather, the controllers may be coupled together to exchange information with each other in a de-centralized manner.
- a number of different network topologies, data protocols, and addressing schemes may be employed in networked lighting systems according to the present invention.
- one or more particular controller addresses may be manually pre-assigned to each controller on the network (e.g., stored in nonvolatile memory of the controller).
- the system may be "self-learning" in that one or more central processors (e.g., servers) may query (i.e., "ping") for the existence of controllers (e.g., clients) coupled to the network, and assign one or more addresses to controllers once their existence is verified.
- a variety of addressing schemes and data protocols may be employed, including conventional Internet addressing schemes and data protocols.
- a particular network topology may dictate an addressing scheme and/or data protocol for the networked lighting system. For example, in one embodiment, addresses may be assigned to respective controllers on the network based on a given network topology and a particular position in the network topology of respective controllers. Similarly, in another embodiment, data may be arranged in a particular manner (e.g., a particular sequence) for transmission throughout the network based on a particular position in the network topology of respective controllers. In one aspect of this embodiment, the network may be considered "self-configuring" in that it does not require the specific assignment of addresses to controllers, as the position of controllers relative to one another in the network topology dictates the data each controller exchanges with the network.
- data ports of multiple controllers are coupled to form a series connection (e.g., a daisy-chain or ring topology for the network), and data transmitted to the controllers is arranged sequentially based on a relative position in the series connection of each controller.
- a series connection e.g., a daisy-chain or ring topology for the network
- data transmitted to the controllers is arranged sequentially based on a relative position in the series connection of each controller.
- each controller in the series connection receives data, it "strips off' one or more initial portions of the data sequence intended for it and transmits the remainder of the data sequence to the next controller in the series connection.
- Each controller on the network in turn repeats this procedure, namely, stripping off one or more initial portions of a received data sequence and transmitting the remainder of the sequence.
- each controller may be configured similarly, and controllers may be flexibly interchanged on the network or added to the network without requiring a system operator or network administrator to reassign addresses.
- Fig. 1 is a diagram illustrating a networked lighting system according to one embodiment of the invention.

- the networked lighting system shown in Fig. 1 is configured essentially using a bus topology; namely, each of the controllers is coupled to a common bus 28.
- a daisy- chain or ring topology for a networked lighting system according to one embodiment of the invention is discussed further below in connection with Fig. 3.
- the network lighting system illustrated in Fig. 1 may employ any of a variety of different addressing schemes and data protocols to transfer data 29 between the processor 22 and one or more controllers 26A, 26B, and 26C, or amongst the controllers. Some examples of addressing schemes and data protocols suitable for purposes of the present invention are discussed in greater detail below.
- each controller 26A, 26B, and 26C of the networked lighting system is coupled to one or more of a variety of devices, including, but not limited to, conventional light sources (e.g., fluorescent or incandescent lights), LED-based light sources, controllable actuators (e.g., switches, relays, motors, etc.), and various sensors (e.g., light, heat, sound/pressure, motion sensors).
- conventional light sources e.g., fluorescent or incandescent lights
- LED-based light sources e.g., LED-based light sources
- controllable actuators e.g., switches, relays, motors, etc.
- sensors e.g., light, heat, sound/pressure, motion sensors.
- controller 26 A is coupled to a fluorescent light 36 A, an LED 40A, and a controllable relay 38; similarly, the controller 26B is coupled to a sensor 42, a fluorescent light source 36B, and a group 40B of three LEDs, and the controller 26C is coupled to three groups 40C ⁇ , 40C 2 , and 40C 3 of LEDs, as well as a fluorescent light source 36C.
- fluorescent light sources illustrated in Fig. 1 are shown schematically as simple tubes; however, it should be appreciated that this depiction is for purposes of illustration only.
- the gas discharge tube of a fluorescent light source typically is controlled by a ballast (not shown in the figures) which receives a control signal (e.g., a current or voltage) to operate the light source.
- a control signal e.g., a current or voltage
- fluorescent light sources generally are understood to comprise a glass tube filled with a vapor, wherein the glass tube has an inner wall that is coated with a fluorescent material.
- Fluorescent light sources emit light by controlling a ballast electrically coupled to the glass tube to pass an electrical current through the vapor in the tube.
- the current passing through the vapor causes the vapor to discharge electrons, which in turn impinge upon the fluorescent material on the wall of the tube and cause it to glow (i.e., emit light).
- a conventional fluorescent light ballast may be controlled by applying an AC voltage (e.g., 120 Volts AC) to the ballast to cause the glass tube to emit light.
- a DC voltage between 0 and 10 Volts DC may be applied to the ballast to incrementally control the amount of light (e.g., intensity) radiated by the glass tube.
- a given controller may be associated with only one device, another controller may be associated with only output devices (e.g., one or more light sources or actuators), another controller may be associated with only input devices (e.g., one or more sensors), and another controller may be associated with any number of either input or output devices, or combinations of input and output devices.

- each input port 31 receives a signal from one or more sensors, for example, which the controller then encodes as data which may be transmitted via the data port 32 throughout the network and identified as corresponding to a signal received at a particular input port of the network.
- particular identifiers may be assigned to each output port and input port of a given controller. This may be accomplished, for example, via software or firmware at the controller (e.g., stored in the memory 48), a particular hardware configuration of the various input and/or output ports, instructions received via the network (i.e., the data port 32) from the processor 22 or one or more other controllers, or any combination of the foregoing.
- the controller is independently addressable in that the controller may receive data intended for multiple devices coupled to output ports of other controllers on the network, but has the capability of selecting and responding to (i.e., selectively routing) particular data to one or more of its output ports, based on the relative configuration of the ports (e.g., assignment of identifiers to ports and/or physical arrangement of ports) in the controller. Furthermore, the controller is capable of transmitting data to the network that is identifiable as corresponding to a particular input signal received at one or more of its input ports 31.
- a sensor 42 responsive to some input stimulus provides a signal to an input port 31 of the controller 26B, which may be particularly accessed (i.e., independently addressed) over the network 24 ⁇ (e.g., by the processor 22) via the data port 32 of the controller 26B.
- some input stimulus e.g., light, sound/pressure, temperature, motion, etc.
- the processor 22 may transmit various data throughout the network, including control information to control one or more particular light sources and/or other devices coupled to any one of the controllers 26A, 26B, and 26C; the controllers in turn each receive the data, and selectively route portions of the data to appropriate output ports to effect the desired control of particular light sources and/or other devices.
- any one of the controllers may function similarly to the processor 22, as discussed above, to first access input data from one or more sensors and then implement various control functions based on the input data.
- a networked lighting system may be implemented to facilitate automated computer-controlled operation of multiple light sources and devices in response to various feedback stimuli (e.g., from one or more sensors coupled to one or more controllers of the network), for a variety of space-illumination applications.
- automated networked lighting applications according to the invention for home, office, retail, commercial environments and the like may be implemented based on a variety of feedback stimuli (e.g., changes in temperature or natural ambient lighting, sound or music, human movement or other motion, etc.) for energy management and conservation, safety, marketing and advertisement, entertainment and environment enhancement, and a variety of other purposes.
- various data protocols and addressing schemes may be employed in networked lighting systems according to the invention.

- three controllers are illustrated in Fig. 3, it should be appreciated that the invention according to this embodiment is not limited in this respect, as any number of controllers may be series-connected to form the network 24 2 .
- networked lighting systems according to various embodiments of the invention may employ any of a number of different addressing schemes and data protocols to transport data. With respect to the networked lighting system shown in Fig.
- the topology of the network 24 2 particularly lends itself to data transport techniques based on token ring protocols.
- the lighting system of Fig. 3 is not limited in this respect, as other data transport protocols may be employed in this embodiment, as discussed further below.
- data is transported through the network 24 2 via a number of data links, indicated as 28A, 28B, 28C, and 28D.
- the controller 26A receives data from the processor 22 on the link 28A and subsequently transmits data to the controller 26B on the link 28B.
- the controller 26B transmits data to the controller 26C on the link 28C.
- the controller 26C may in turn optionally transmit data to the processor 22 on the link 28D, thereby forming a ring topology for the network 24 2 .
- data link 3 need not form a closed ring (as indicated by the dashed line for the data link 28D), but instead may form an open daisy-chain.
- data may be transmitted to the network 24 2 from the processor 22 (e.g., via the data link 28A), but the processor 22 need not necessarily receive any data from the network 24 2 (e.g., there need not be any physical connection to support the data link 28D).
- the data transported on each of the data links 28A-28D may or may not be identical; i.e., stated differently, according to various embodiments, the controllers 26A, 26B, and 26C may or may not receive the same data. Additionally, as discussed above in connection with the system illustrated in Fig. 1, it should be appreciated generally that the particular types and configuration of various devices coupled to the controllers 26A, 26B, and 26C shown in Fig. 3 is for purposes of illustration only.

- Fig. 4 is a diagram illustrating a data protocol based on a particular arrangement of data that may be used in the networked lighting system of Fig. 3, according to one embodiment of the invention.
- Fig. 4 is a diagram illustrating a data protocol based on a particular arrangement of data that may be used in the networked lighting system of Fig. 3, according to one embodiment of the invention.
- a sequence 60 of data bytes B1-B10 is illustrated, wherein the bytes B1-B3 constitute a first portion 62 of the sequence 60, the bytes B4-B6 constitute a second portion 64 of the sequence 60, and the bytes B7-B10 constitute a third portion 66 of the sequence 60. While Fig. 4 shows a sequence often data bytes arranged in three portions, it should be appreciated that the invention is not limited in this respect, and that the particular arrangement and number of data bytes shown in Fig. 4 is for purposes of illustration only.
- the exemplary protocol shown in Fig. 4 may be used in the network lighting system of Fig. 3 to control various output devices (e.g., a number of light sources and/or actuators) coupled to one or more of the controllers 26A, 26B, 26C.
- output devices e.g., a number of light sources and/or actuators
- the sensor 42 coupled to an input port 31 of the controller 26B shown in Fig. 3 is replaced by a light source coupled to an output port 30; namely, the controller 26B is deemed to have three independently controllable output ports 30 respectively coupled to three light sources, rather than two output ports 30 and one input port 31.
- the data sequence 60 initially is transmitted from the processor 22 to the controller 26A via the data link 28A, and the data bytes Bl -BIO are particularly arranged in the sequence based on the relative position of the controllers in the series connection forming the network 24 2 .
- the data bytes B1-B3 of the first portion 62 of the data sequence 60 respectively correspond to data intended for the three output ports 30 of the controller 26A.
- the data bytes B4-B6 of the second portion 64 of the sequence respectively correspond to data intended for the three output ports 30 of the controller 26B.
- the data bytes B7-B10 of the third portion 66 of the sequence respectively correspond to data intended for the four output ports 30 of the controller 26C.
- each controller 26A, 26B, and 26C is programmed to receive data via the input terminal 32A of the data port 32, "strip off' an initial portion of the received data based on the number of output ports supported by the controller, and then transmit the remainder of the received data, if any, via the output terminal 32B of the data port 32.
- the controller 26A receives the data sequence 60 from the processor 22 via the data link 28 A, strips off the first portion 62 of the three bytes B1-B3 from the sequence 60, and uses this portion of the data to control its three output ports. The controller 26A then transmits the remainder of the data sequence, including the second and third portions 64 and 66, respectively, to the controller 26B via the data link 28B.
- the controller 26B strips off the second portion 62 of the three bytes B4-B6 from the sequence (because these now constitute the initial portion of the data sequence received by the controller 26B), and uses this portion of the data to control its three output ports.
- the controller 26B then transmits the remainder of the data sequence (now including only the third portion 66) to the controller 26C via the data link 28C.
- the controller 26C strips off the third portion 66 (because this portion now constitutes the initial and only portion of the data sequence received by the controller 26C), and uses this portion of the data to control its four output ports'.
- While the particular configuration of the networked lighting system illustrated in Fig. 3 includes a total often output ports (three output ports for each of the controllers 26A and 26B, and four output ports for the controller 26C), and the data sequence 60 shown in Fig. 4 includes at least ten corresponding data bytes B1-B10, it should be appreciated that the invention is not limited in this respect; namely, as discussed above in connection with Fig. 2, a given controller may be designed to support any number of output ports. Accordingly, in one aspect of this embodiment, it should be appreciated that the number of output ports supported by each controller and the total number of controllers coupled to form the network 24 2 dictates the sequential arrangement, grouping, and total number of data bytes of the data sequence 60 shown in Fig. 4.
- each controller is designed identically to support four output ports; accordingly, in this embodiment, a data sequence similar to that shown in Fig. 4 is partitioned into respective portions of at least four bytes each, wherein consecutive four byte portions of the data sequence are designated for consecutive controllers in the series connection.
- the network may be considered "self-configuring" in that it does not require the specific assignment of addresses to controllers, as the position of controllers relative to one another in the series connection dictates the data each controller responds to from the network.
- each controller may be configured similarly (e.g., programmed to strip off an initial four byte portion of a received data sequence), and controllers may be flexibly interchanged on the network or added to the network without requiring a system operator or network administrator to reassign addresses.
- a system operator or programmer need only know the relative position of a given controller in the series connection to provide appropriate data to the controller.
- one or more of the data bytes of the sequence 60 may correspond to digital values representing corresponding input signals received at particular input ports of one or more controllers.
- the data sequence 60 may be arranged to include at least one byte for each input port and output port of the controllers coupled together to form the network 24 2 , wherein a particular position of one or more bytes in the sequence 60 corresponds to a particular input or output port.
- the byte B4 of the data sequence 60 may correspond to a digital value representing an input signal received at the input port 31 of the controller 26B.
- each controller instead may be programmed to receive and transmit the entire data sequence 60. Upon receiving the entire data sequence 60, each controller also may be programmed to appropriately index into the sequence to extract the data intended for its output ports, or place data into the sequence from its input ports. In this embodiment, so as to transmit data corresponding to one or more input ports to the processor 22 for subsequent processing, the data link 28D is employed to form a closed ring topology for the network 24 2 .
- the processor 22 may be programmed to initially transmit a data sequence 60 to the controller 26A having "blank" bytes (e.g., null data) in positions corresponding to one or more input ports of one or more controllers of the network 24 2 . As the data sequence 60 travels through the network, each controller may place data corresponding to its input ports, if any, appropriately in the sequence. Upon receiving the data sequence via the data link 28D, the processor 22 may be programmed to extract any data corresponding to input ports by similarly indexing appropriately into the sequence.
- "blank" bytes e.g., null data
- the data protocol shown in Fig. 4 may be based at least in part on the DMX data protocol.
- the DMX data protocol is discussed, for example, in U.S. Patent No. 6,016,038, referenced above.
- each byte B1-B10 of the data sequence 60 shown in Fig. 4 corresponds to a digital value in a range of 0-255.
- this digital value may represent a desired output value for a control signal provided by a particular output port of a controller; for example, the digital value may represent an analog voltage level provided by an output port, or a pulse-width of a pulse width modulated signal provided by an output port.
- this digital value may represent some parameter (e.g., a voltage or current value, or a pulse-width) of a signal received at a particular input port of a controller.
- some parameter e.g., a voltage or current value, or a pulse-width
- one or more of the data bytes of the sequence 60 may correspond to an assigned address (or group of addresses) for one or more of the controllers 26A, 26B, and 26C.
- the byte Bl may correspond to an address (or starting address of a range of addresses) for the controller 26A
- the byte B2 may correspond to an address (or starting address of a range of addresses) for the controller 26B
- the byte B3 may correspond to an address (or starting address of a range of addresses) for the controller 26C.
- the other bytes of the data sequence 60 shown in Fig. 4 respectively may correspond to addresses for other controllers, or may be unused bytes.
- the processor 22 transmits at least the bytes B1 -B3 to the controller 26A.
- the controller 26A stores the first byte Bl (e.g., in its memory 48, as shown in Fig. 2) as an address, removes Bl from the data sequence, and transmits the remaining bytes to the controller 26B.
- the controller 26B receives the remaining bytes B2 and B3, stores the first received byte (i.e., B2) as an address, and transmits the remaining byte B3 to the controller 26C, which in turn stores the byte B3 (the first received byte) as an address.
- each controller in the series connection forming the network 24 2 dictates the address (or starting address of a range of addresses) assigned to the controller initially by the processor, rather than the data itself to be processed by the controller.
- each controller may be programmed to receive and re-transmit all of the data initially transmitted by the processor 22 on the data link 28A; stated differently, in one aspect of this embodiment, once each controller is assigned an address, the sequence of data transmitted by the processor 22 is not constrained by the particular topology (i.e., position in the series connection) of the controllers that form the network 24 2 .
- each controller does not need to be programmed to appropriately index into a data sequence to extract data from, or place data into, the sequence. Rather, data corresponding to particular input and output ports of one or more controllers may be formatted with an "address header" that specifies a particular controller, and a particular input or output port of the controller.
- the processor 22 may transmit a data sequence having an arbitrary predetermined number of data bytes corresponding to controller addresses to be assigned. As discussed above, each controller in the series connection in turn extracts an address from the sequence and passes on the remainder of the sequence. Once the last controller in the series connection extracts an address, any remaining addresses in the sequence may be returned to the processor 22 via the data link 28D. In this manner, based on the number of bytes in the sequence originally transmitted by the processor 22 and the number of bytes in the sequence ultimately received back by the processor, the processor may determine the number of controllers that are physically coupled together to form the network 24 2 .
- the processor 22 shown in Fig. 3 may transmit an initial controller address to the controller 26A, using one or more bytes of the data sequence 60 shown in Fig. 4.
- the controller 26A may store this address (e.g., in nonvolatile memory), increment the address, and transmit the incremented address to the controller 26B.
- the controller 26B in turn repeats this procedure; namely, storing the received address, incrementing the received address, and transmitting the incremented address to the next controller in the series connection (i.e., the controller 26C).
- the last controller in the series connection e.g., the controller 26C in the example shown in Fig.
- the processor 22 transmits either the address it stored or an address that is incremented from the one it stored to the processor 22 (e.g., via the data link 28D in Fig. 3). In this manner, the processor 22 need only transmit to the network an initial controller address, and based on the address it receives back from the network, the processor may determine the number of controllers that are physically coupled together to form the network 24 2 .
- processor 22 and the controllers can be implemented in numerous ways, such as with dedicated hardware, or using one or more microprocessors that are programmed using software (e.g., microcode) to perform the various functions discussed above.
- one implementation of the present invention comprises one or more computer readable media (e.g., volatile and non-volatile computer memory such as PROMs, EPROMs, and EEPROMs, floppy disks, compact disks, optical disks, magnetic tape, etc.) encoded with one or more computer programs that, when executed on one or more processors and/or controllers, perform at least some of the above-discussed functions of the present invention.
- the one or more computer readable media may be fixed within a processor or controller or may be transportable, such that the one or more programs stored thereon can be loaded into a processor or controller so as to implement various aspects of the present invention discussed above.
- the term "computer program” is used herein in a generic sense to refer to any type of computer code (e.g., software or microcode) that can be employed to program one or more microprocessors so as to implement the above-discussed aspects of the present invention.
- the term "LED” should be understood to include light emitting diodes of all types (including semi-conductor and organic light emitting diodes), semiconductor dies that produce light in response to current, light emitting polymers, electro-luminescent strips, and the like. Furthermore, the term “LED” may refer to a single light emitting device having multiple semiconductor dies that are individually controlled. It should also be understood that the term “LED” does not restrict the package type of an LED; for example, the term “LED” may refer to packaged LEDs, non-packaged LEDs, surface mount LEDs, chip-on-board LEDs, and LEDs of all other configurations. The term “LED” also includes LEDs packaged or associated with phosphor, wherein the phosphor may convert radiant energy emitted from the LED to a different wavelength.
- the term "light source” should be understood to include all illumination sources, including, but not limited to, LED-based sources as defined above, incandescent sources (e.g., filament lamps, halogen lamps), pyro- luminescent sources (e.g., flames), candle-luminescent sources (e.g., gas mantles), carbon arc radiation sources, photo-luminescent sources (e.g., gaseous discharge sources), fluorescent sources, phosphorescent sources, high-intensity discharge sources (e.g., sodium vapor, mercury vapor, and metal halide lamps), lasers, electro-luminescent sources, cathode luminescent sources using electronic satiation, galvano-luminescent sources, crystallo-luminescent sources, kine-luminescent sources, thermo-luminescent sources, triboluminescent sources , sonoluminescent sources, radioluminescent sources, and luminescent polymers capable of producing primary colors.
- incandescent sources e.g., filament lamps, hal
- color should be understood to refer to any frequency (or wavelength) of radiation within a spectrum; namely, “color” refers to frequencies (or wavelengths) not only in the visible spectrum, but also frequencies (or wavelengths) in the infrared, ultraviolet, and other areas of the electromagnetic spectrum.
