Referring to FIG. 3, a first embodiment of a lamp control system according to the disclosure includes a plurality of lamp networks (31 to 3n) and a lamp control gateway 4. The lamp control gateway 4 includes a plurality of transmission interfaces (41 to 4n) and a processing module 5. The transmission interfaces (41 to 4n) respectively comply with different standards in physical layer, and are respectively coupled to the lamp networks (31 to 3n). The processing module 5 is coupled to each of the transmission interfaces (41 to 4n) for two-way communication therethrough with one of the lamp networks (31 to 3n) that is coupled thereto. In other words, each transmission interface (41 to 4n) transmits signals to and receives signals from the respective lamp network (31 to 3n) according to the respective standard.
In this embodiment, the processing module 5 includes a protocol unit 6 and a plurality of controllers (51 to 5n). The protocol unit 6 complies with a predefined protocol in media access control (MAC) layer. Each of the controllers (51 to 5n) complies with a respective one of the standards in physical layer, and is coupled between the protocol unit 6 and a corresponding one of the transmission interfaces (41 to 4n) that complies with the same standard. The protocol unit 6 handles, according to the predefined protocol, signal flow among the controllers (51 to 5n). Each of the controllers (51 to 5n) modulates, according to the respective standard, a signal from the protocol unit 6 and outputs a modulated signal to the corresponding one of the transmission interfaces (41 to 4n), and demodulates, according to the respective standard, a signal from the corresponding one of the transmission interfaces (41 to 4n) and outputs a demodulated signal to the protocol unit 6.
In this embodiment, each of the lamp networks (31 to 3n) includes a master controller 311 and a lamp set 321 (only those of the lamp network 31 are labeled). The master controller 311 of each lamp network (31 to 3n) complies in physical layer with the standard with which the respective one of the transmission interfaces (41 to 4n) complies, complies with the predefined protocol in MAC layer, and is coupled to the respective one of the transmission interfaces (41 to 4n) for two-way communication with the processing module 5 therethrough. The lamp set 321 of each lamp network (31 to 3n) includes at least one lamp device 331 that complies in physical layer with the standard with which the respective one of the transmission interfaces (41 to 4n) complies, that complies with the predefined protocol in MAC layer, and that is coupled to the master controller 311 for two-way communication therewith. In other words, the master controller 311 transmits signals to and receives signals from the respective transmission interface 41 and the at least one lamp device 331 of the lamp set 321 according to the respective standard, and handles signal flow between the respective transmission interface 41 and the at least one lamp device 331 of the lamp set 321 according to the predefined protocol, and the at least one lamp device 331 of the lamp set 321 transmits signals to and receives signals from the master controller 311 according to the corresponding standard, and acts in response to each received signal according to the predefined protocol.

FIG. 5 illustrates a second exemplary implementation of the lamp control system of this embodiment. In the second exemplary implementation, the standards include standards of DALI and PLC, and the predefined protocol is a protocol of DALI.
In addition, the controllers respectively complying with the standards of DALI and PLC in physical layer are respectively referred to as a DALI controller 81 and a PLC controller 82; the transmission interfaces respectively complying with the standards of DALI and PLC in physical layer are respectively referred to as a DALI transmission interface 41 and a PLC transmission interface 42; the master controllers respectively complying with the standards of DALI and PLC in physical layer are respectively referred to as a DALI master controller 311 and a PLC master controller 321; each lamp set, the at least one lamp device (not shown) of which complies with a respective one of the standards of DALI and PLC in physical layer, is referred to as a respective one of a DALI lamp set 312 and a PLC lamp set 322; the lamp network including the DALI master controller 311 and the DALI lamp set 312 is referred to as a DALI lamp network 31; and the lamp network including the PLC master controller 321 and the PLC lamp set 322 is referred to as a PLC lamp network 32.
Moreover, the DALI controller 81 includes a Manchester encoder 811 and a Manchester decoder 812, and the PLC controller 82 includes a pulse encoder 821 and a pulse decoder 822.

In the implementation shown in FIG. 5, two different types of transmission media, including DALI buses and power lines, are used. The DALI buses are used for signal transmission between the DALI transmission interface 41 and the DALI master controller 311 and between the DALI master controller 311 and the at least one lamp device (not shown) of the DALI lamp set 312. The power lines are used for signal transmission between the PLC transmission interface 42 and the PLC master controller 321 and between the PLC master controller 321 and the at least one lamp device (not shown) of the PLC lamp set 322.
Referring back to FIG. 3, in this embodiment, when the master controller of a first one of the lamp networks (31 to 3n) (e.g., the DALI master controller 311 of the DALI lamp network 31 shown in FIG. 4 or 5) sends a query signal to the lamp set of a second one of the lamp networks (31 to 3n) (e.g., the PLC lamp set 321 of the PLC lamp network 32 shown in FIG. 4 or 5) for enabling the lamp set of the second lamp network to send a response signal to the master controller of the first lamp network, this query action is deemed valid if a time period from the output of the query signal by the master controller of the first lamp network to the receipt of the response signal by the same is within a range from 2.9 ms to 9.17 ms as specified by a lamp control standard, and is otherwise deemed invalid. Since converters are not required by the lamp control system of this embodiment, processing time of each of the query and response signals is relatively short, and thus the aforesaid timing requirement can be met easily.
Referring to FIG. 6, a second embodiment of a lamp control system according to the disclosure is a modification of the first embodiment, and includes at least one first lamp network 31, at least one second lamp network 32 and a lamp control gateway 7.
The first lamp network 31 is configured to emit light and to transmit a first message, and includes a first physical layer. The second lamp network 32 is configured to emit light and to transmit a first message, and includes a second physical layer different from the first physical layer.
The lamp control gateway 7 includes at least one first transmission interface 41, at least one second transmission interface 42 and a processing module 8.
The first transmission interface 41 includes a first gateway physical layer that complies with a standard with which the first physical layer of the first lamp network 31 complies, and is coupled between the processing module 8 and the first lamp network 31.
The second transmission interface 42 includes a second gateway physical layer that complies with a standard with which the second physical layer of the second lamp network 32 complies, and is coupled between the processing module 8 and the second lamp network 32.
The processing module 8 communicates with the first lamp network 31 and the second lamp network 32 respectively through the first transmission interface and the second transmission interface 42. The processing module 8 is configured to receive the first message and the second message and to convert the first message and the second message in such a way that a first converted message and a second converted message comply with a predefined protocol. As a result, messages in different protocol languages (e.g., the first message and the second message) that are respectively transmitted by different lamp networks (e.g., the first lamp network 31 with the first physical layer and the second lamp network 32 with the second physical layer) could be converted by a single lamp control gateway (e.g., the lamp control gateway 7) based on same protocol language information in accordance with the predefined protocol.
In this embodiment, the processing module 8 includes a protocol unit 6, at least one first controller 81 and at least one second controller 82.
The protocol unit 6 includes a media access control (MAC) layer that complies with the predefined protocol.
The first controller 81 is coupled between the protocol unit 6 and the first transmission interface 41.
The second controller 82 is coupled between the protocol unit 6 and the second transmission interface 42.
Each of the first controller 81 and the second controller 82 modulates a signal from the protocol unit 6 and outputs a modulated signal to the first transmission interface 41 and/or the second transmission interface 42 (e.g., the first controller 81 outputs the modulated signal directly to the first transmission interface 41 and indirectly to the second transmission interface 42), and demodulates a signal (e.g., the first message and/or the second message) from the first transmission interface 41 and the second transmission interface 42 and outputs a demodulated signal to the protocol unit 6 for subsequent conversion into a converted signal (e.g., the first converted message and/or the second converted message).
In one exemplary implementation of this embodiment, the first lamp network 31 has a MAC layer that complies with a first protocol, the second lamp network 32 has a MAC layer that complies with a second protocol different from the first protocol, and the predefined protocol is different from the first and second protocols. For example, the predefined protocol is a protocol of DALI, the first protocol is a protocol of PLC, and the second protocol is a protocol of CAN.
In another exemplary implementation of this embodiment, the first lamp network 31 has a MAC layer that complies with a first protocol, the second lamp network 32 has a MAC layer that complies with a second protocol different from the first protocol, and the predefined protocol is identical with one of the first and second protocols. For example, the predefined protocol is a protocol of DALI, the first protocol is a protocol of DALI, and the second protocol is a protocol of CAN.
Referring to FIG. 7, a third embodiment of a lamp control system according to the disclosure is a modification of the second embodiment, and differs from the second embodiment in that at least one slave lamp network 71 is used to replace the first lamp network 31 (see FIG. 6), and that at least one master network 72 is used to replace the second lamp network 32 (see FIG. 6).
In this embodiment, the slave lamp network 71 is configured to emit light, and includes a first physical layer. The master network 72 includes a second physical layer different from the first physical layer, and is configured to send a command set. The processing module 8 is configured to receive the command set from the master network 72 through the second transmission interface 42, converts the command set in such a way that a converted command set complies with a predefined protocol, and transmits the converted command set to the slave lamp network 71 through the first transmission interface 41.
As shown in FIG. 8, the master network 72 may include a terminal setter 73 for outputting the command set based on an input, and the terminal setter 73 may be one of a portable device 731, a wired device 732, and a wireless device 733.
The slave lamp network 71 may have a MAC layer that complies with a slave protocol, the master network 72 may have a MAC layer that complies with a master protocol different from the slave protocol, and the predefined protocol may be identical with the slave protocol. In this case, the command set that is outputted by the terminal setter 73 and that complies with the master protocol different from the slave protocol could be converted by the lamp control gateway 7 based on same protocol language information in accordance with the predefined protocol identical with the slave protocol, such that the slave lamp network 71 could execute the converted command set.
For example, in one embodiment, a master network is configured to provide control signals to the respective slave control units of each slave lamp network within a lamp control system. Such control signals may be communicated by the master network over, for example, a private, shared, and/or proprietary communications network, such as DALI or DMX, to control the slave lamp network of the system.
It will be appreciated that the master network may provide external input to various slave lamp networks of the lighting system via direct communication with the slave control unit of each device, or via indirect communication, for example, via one or more intermediary communication devices and/or I/O modules. In the embodiments using indirect communication, the I/O module may be configured to provide instructions to a slave control unit of a given lighting device, wherein the I/O module is configured, for example, as a communication port. A communication port can be configured to receive and send information in one or more of a plurality of communication protocols, which may include for example, DMX, DALI, RS-485, I2C, RS-232, the Ethernet, a proprietary protocol or other communication protocol as would be readily understood by a person skilled in the art.
A standard protocol control interface can be employed when the presets which are desired to be performed by the lighting module are complex and may not be appropriately controlled using a manual control interface. For example, a standard protocol can be DALI, DMX or other standard protocols as would be readily understood by a person skilled in the art. In one embodiment, the master network is configured to be a standard protocol controller, for example a DMX controller or a DALI controller.
The term “control protocol” is used to define a protocol by which control parameters, instructions, processes, commands, etc. may be communicated to and/or implemented by one or more lighting modules and/or devices of a lighting system (e.g., as described herein), or control interface and/or light generation module(s) thereof, either directly or indirectly, to ultimately control a luminous output of the lighting device/module(s) of the system. A control protocol as used herein may include, but is not limited to, alighting device control process (e.g., method, process, algorithm, etc.); a data format of an input for, or an output of such a process; a set of units and/or parameter s by which the controlled output of the one or more slave lamp networks, or of its one or more constituents, may be defined; a communication protocol by which such parameters, inputs and/or outputs may be communicated between various components and/or modules of a given lighting system; a proprietary or industry standard for defining various control parameters, communicating such parameters between various components/modules of a control system and/or operating and interfacing with such components for the implementation of a control sequence or process, for example. It will be appreciated that such control protocol s may be implemented to control various elements and/or functions of the one or more slave lamp networks (e.g., lighting device intensity, chromaticity, spectral power distribution, colour quality or rendering ability, luminous efficacy, wall-plug efficiency, etc.), such as via one or more control interfaces and/or light generation modules integrated therein or operatively coupled thereto, as well as provide administrative control of the control interface module(s), light generation module(s), and/or other such firmware/software modules (e.g., system update and/or upgrade, etc.).
Referring to FIG. 9, an embodiment of a control system according to the disclosure is a modification of the second embodiment of the lamp control system, and differ s from the second embodiment of the lamp control system in that a plurality of networks (e.g., networks 91, 92 in FIG. 9) are used to replace the first lamp network 31 (see FIG. 6) and the second lamp network 32 (see FIG. 6), and that a control gateway 7′ is used to replace the lamp control gateway 7 (see FIG. 6).
In this embodiment, at least one of the networks (e.g., the network 91 in FIG. 9) includes a physical layer (e.g., a first physical layer in FIG. 9) different from that (e.g., a second physical layer in FIG. 9) of each of remaining one(s) of the networks (e.g., the network 92 in FIG. 9), and is configured to send a command set.
In one exemplary implementation of this embodiment, the at least one of the networks (e.g., the network 91 in FIG. 9) may have a MAC layer that complies with a first protocol, the remaining one(s) of the networks (e.g., the network 92 in FIG. 9) may have a MAC layer that complies with a second protocol different from the first protocol, and the predefined protocol may be identical with one of the first and second protocols.
In another exemplary implementation of this embodiment, the at least one of the networks (e.g., the network 91 in FIG. 9) may have a MAC layer that complies with a first protocol, the remaining one(s) of the networks (e.g., the network 92 in FIG. 9) may have a MAC layer that complies with a second protocol different from the first protocol, and the predefined protocol may be different from the first and second protocols.
As shown in FIG. 10, the at least one of the networks (e.g., the network 91 in FIG. 9) may include a terminal setter 93 for outputting the command set based on an input. The terminal setter 93 may be one of a portable device 931, a wired device 932 and a wireless device 933. At least one of the remaining one (s) of the networks (e.g., the network 92 in FIG. 9) may include a controlled terminal 94 for receiving the converted command set, and for executing the converted command set. The controlled terminal 94 may be one of a lamp 941, a home appliance 942 and a consumer electronic device 943. Since power lines exist in houses and public environments, the power lines could be used for signal transmission between the control gateway 7′ and the terminal setter 93 and between the control gateway 7′ and the controlled terminal 94. The control gateway 7′ could communicate through the power lines with the terminal setter 91 or the controlled terminal 94 that complies with a standard of, for example, DALI, DMX, CAN or RS-485 and that does not include converters which are paired with the terminal setter 91 or the controlled terminal 94. This is advantageous in realizing Internet of Things (IoT) service over the power lines that have now existed, without setting up Internet or Intranet in advance.
In view of the above, each of the aforesaid embodiments has the following advantages:
1. Signals, messages or command sets are transmitted via multiple types of transmission media.
2. Since converters are not required, hardware cost is relatively low, and the timing requirement of the lamp control standard between different-protocol networks can be met easily.
3. Since the (lamp) control gateway 4, 7, 7′ includes multiple transmission interfaces 41-4n, 41, 42 with different (gateway) physical layers, the (lamp) control gateway 4, 7, 7′ can provide diverse selections in accordance with the type of physical layer in different networks.
Besides, since the control gateway 7′ includes multiple transmission interfaces 41, 42 with different gateway physical layers to support networks with different type of physical layer, such as the lamp 941, the home appliance 942 or the consumer electronic device 943, the control gateway 7′ can be used in realizing Internet of Things (IoT) service.
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects.
While the disclosure has been described in connection with what are considered the exemplary embodiments, it is understood that this disclosure is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
