[0008] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0009] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0010] (Embodiment) [composition] First, an overview of a device control system according to an embodiment will be described below. Fig. 1 is a block diagram showing a functional configuration of the device control system according to an embodiment.

[0011] The device control system 10 according to the first embodiment is a PoE system (a PoE-based system) that uses the PoE mechanism to control a target device. The device control system 10 includes a power supply device 20 (PSE: Power Sourcing Equipment), a lighting device 30, an adapter 40, and a lighting device 50. The lighting device 30 and the adapter 40 are powered devices (PD: Powered Devices) in the PoE system. The powered devices may be air conditioners, cameras, audio devices (speakers), video devices, disaster prevention devices, sensors, user interface devices, or the like.

[0012] The power supply device 20 includes a plurality of connection ports 21, a power supply control unit 22, and a storage unit 23. The plurality of connection ports 21 are connection structures to which standard cables 70 conforming to the Ethernet (registered trademark) standard are connected, specifically, RJ-45 type connectors. Specifically, the standard cables 70 are so-called LAN (Local Area Network) cables or the like. The power receiving devices are electrically connected to the connection ports 21 via the standard cables 70. The power receiving devices (lighting devices 30 and adapters 40) are supplied with power from the power supply device 20 via the standard cables 70, and can communicate with the power supply device 20 via the standard cables 70.

[0013] The power supply control unit 22 supplies power to the power receiving device connected to the connection port 21. The power supply control unit 22 also controls the power receiving device connected to the connection port 21 by transmitting a first control signal to the power receiving device via the standard cable 70. The power supply control unit 22 is specifically realized by a microcomputer or a processor, and is built into the power supply device 20. The function of the power supply control unit 22 is realized, for example, by the microcomputer or processor constituting the power supply control unit 22 executing a computer program stored in the storage unit 23.

[0014] The storage unit 23 is a storage device that stores the computer program and various information necessary for supplying power to the power receiving device, etc. The storage unit 23 is realized by, for example, a semiconductor memory.

[0015] The lighting device 30 is connected to one of the multiple connection ports 21 via a standard cable 70, and operates by receiving power supply from the power supply device 20 via the standard cable 70. The lighting device 30 is, for example, a lighting device that illuminates an indoor space, and more specifically, is a base light, a system ceiling light, a downlight, or a spotlight. The specific embodiment of the lighting device 30 is not particularly limited. For example, a light-emitting element such as an LED (Light Emitting Diode) or an organic EL (Electro Luminescence) is used as a light source of the lighting device 30.

[0016] The adapter 40 is a device for operating a device to which the standard cable 70 cannot be connected (i.e., cannot be connected to the power supply device 20) as a power receiving device. The adapter 40 is connected to one of the multiple connection ports 21 via the standard cable 70, and can receive power from the power supply device 20 via the standard cable 70. Specifically, the adapter 40 has an input unit 41, a PD interface 42, a power conversion circuit 43, a signal conversion circuit 44, and a connection structure 45.

[0017] The input unit 41 is a connection structure to which the standard cable 70 is connected, and is specifically an RJ-45 type connector. The adapter 40 has the input unit 41, and is connected to one of the multiple connection ports 21 via the standard cable 70.

[0018] The PD interface 42 is an interface unit for performing power-related processing such as power class classification processing. The PD interface 42 is realized by, for example, a microcomputer or a processor. The functions of the PD interface 42 are realized by the microcomputer or the processor executing a computer program stored in an internal or external memory.

[0019] The power conversion circuit 43 converts the power supplied from the power supply device 20 via the standard cable 70 into power suitable for the lighting device 50 (a device connected to the connection structure 45) and outputs the converted power. The power supplied from the power supply device 20 is DC power, and the power suitable for the lighting device 50 may be DC power or AC power. The power conversion circuit 43 is realized by a DC-DC converter circuit, an inverter circuit, and the like. It is not essential that the adapter 40 has the power conversion circuit 43, and if the power supplied from the power supply device 20 can be supplied directly to the lighting device 50, the adapter 40 does not need to have the power conversion circuit 43.

[0020] The signal conversion circuit 44 converts the first control signal received by the adapter 40 from the power supply device 20 via the standard cable 70 into a second control signal in a format suitable for the lighting device 50. The first control signal is, for example, a control signal conforming to Ethernet (registered trademark), and the second control signal is, for example, a PWM signal or a DALI (registered trademark) signal. i The control signal is compliant with the Digital Addressable Lighting Interface (GILI). It is not essential that the adapter 40 has the signal conversion circuit 44. In the case where the lighting device 50 only turns on and off in response to the power supplied from the power supply device 20, the adapter 40 does not need to have the signal conversion circuit 44.

[0021] The connection structure 45 is a connection structure to which the lighting device 50 is connected, and is a structure having a different shape and size from the input unit 41. There are cases where the lighting device 50 is directly connected to the connection structure 45, and cases where the lighting device 50 is indirectly connected to the connection structure 45. The case where the lighting device 50 is indirectly connected is, for example, a case where a power supply device for the lighting device 50 or a cable for the lighting device 50 is connected to the connection structure 45. Specific examples of the connection structure 45 will be described later.

[0022] The lighting device 50 is a device that does not have a PD interface and cannot be connected to the standard cable 70 (i.e., cannot be directly connected to the power supply device 20). The lighting device 50 is, for example, a lighting device that illuminates an indoor space, and more specifically, is a base light, a system ceiling light, a downlight, or a spotlight. The specific embodiment of the lighting device 50 is not particularly limited. For example, a light-emitting element such as an LED or an organic EL is used as the light source of the lighting device 50.

[0023] Note that the device connected to the adapter 40 (connection structure 45) is not limited to the lighting device 50. The device connected to the adapter 40 may be an air conditioner, a camera, an audio device (speaker), a video device, a disaster prevention device, a sensor, or the like.

[0024] As described above, by including the adapter 40, the device control system 10 can control the lighting device 50 that cannot be connected to the power supply device 20 (that does not have a socket for the standard cable 70).

[0025] [Example 1 of adapter and lighting equipment] Next, a first concrete example of the adapter 40 and the lighting device 50 will be described. FIG.

[0026] The lighting device 50a shown in Fig. 2 includes a power supply device 51a and a lighting device main body 52a. The power supply device 51a has a quick-connect terminal 51a1, into which a power cable for receiving power from a commercial power source is usually inserted. The power supply device 51a converts AC power supplied from the commercial power source into DC power and outputs the DC power. The lighting device main body 52a is a downlight, and is connected to the power supply device 51a by a cable 72. The lighting device main body 52a operates using the DC power output from the power supply device 51a.

[0027] The adapter 40a shown in FIG. 2 has an input unit 41 and a quick-connect terminal 45a as a connection structure 45 in order to incorporate such a lighting device 50a into the device control system 10. One end of a cable 71 is inserted into the quick-connect terminal 45a, and the other end of the cable 71 is inserted into the quick-connect terminal 51a1. A power conversion circuit 43 (not shown in FIG. 2) included in the adapter 40a outputs AC power substantially the same as that of a commercial power source, and this AC power is supplied to the power supply device 51a via the quick-connect terminal 45a and the cable 71. In this way, the adapter 40a can operate the lighting device 50a, which normally operates with power supplied from a commercial power source, with power supplied from the power supply device 20.

[0028] When the quick-connect terminal 45a and the quick-connect terminal 51a1 include a control terminal for transmitting a second control signal, the second control signal outputted by the signal conversion circuit 44 can also be used to control the lighting device 50a.

[0029] [Example 2 of adapter and lighting equipment] Next, a second concrete example of the adapter 40 and the lighting device 50 will be described. FIG.

[0030] The lighting device 50b shown in Fig. 3 corresponds to a light source unit of a downlight (an example of a lighting system) that is composed of a fixture body and a light source unit that is detachably attached to the fixture body. The lighting device 50b has a base 51b. The lighting device 50b is attached to the adapter 40b by rotating it, but it may also be attached to the adapter 40b by simply pushing it in, and there is no particular limitation on the method of attaching (detaching) the lighting device 50b to the adapter 40b.

[0031] 3 corresponds to the fixture body of a downlight, which is composed of a fixture body and a light source unit that is detachably attached to the fixture body, and has a structure similar to that of the fixture body. To incorporate the lighting device 50b into the device control system 10, the adapter 40b has an input unit 41 and a terminal structure 45b as a connection structure 45. The terminal structure 45b has a structure corresponding to the base 51b.

[0032] Specifically, the base 51b is a GH76p type base, and includes a pair of power terminals 51b1, a pair of control terminals 51b2, a ground terminal 51b3, and a heat dissipation plate 51b4, as shown in Fig. 4. Fig. 4 is a diagram showing a specific structure of the base 51b.

[0033] The terminal structure 45b has a structure corresponding to such a GH76p type base. A power conversion circuit 43 (not shown in FIG. 3) included in the adapter 40b outputs power suitable for the lighting device 50b, and a signal conversion circuit 44 (not shown in FIG. 3) outputs a second control signal suitable for the lighting device 50b. The output power and the output second control signal are supplied to the lighting device 50b via the terminal structure 45b. This enables the adapter 40b to operate the lighting device 50b by power supply from the power supply device 20.

[0034] The lighting device 50b is attached to and detached from the adapter 40b by a general user, but since the lighting device 50b itself does not have the input unit 41, the general user does not need to insert the standard cable 70 into the lighting device 50b. In other words, the general user can easily attach and detach the lighting device 50b to and from the adapter 40b. In addition, since the lighting device 50b itself does not have the input unit 41, there is also an advantage that the entire surface of the heat dissipation plate 51b4 can be used for heat dissipation.

[0035] [Example 3 of adapter and lighting equipment] Next, a third concrete example of the adapter 40 and the lighting device 50 will be described. FIG.

[0036] A lighting device 50c shown in FIG. 5 is a spotlight, which is connected to a wiring duct (sometimes called a duct rail) connected to a commercial power source, and is operated by receiving power from the wiring duct.

[0037] 5 has an adapter body 46c and a wiring duct 45c as a connection structure 45 in order to incorporate such a lighting device 50c into the device control system 10. The adapter body 46c is configured by accommodating an input unit 41, a PD interface 42, a power conversion circuit 43, and a signal conversion circuit 44 (none of which are shown in FIG. 5) in a housing.

[0038] The power conversion circuit 43 included in the adapter main body 46c can supply power equivalent to that of a commercial power source to the lighting device 50c via the wiring duct 45c. This allows the adapter 40c to operate the lighting device 50c, which is operated by power supply from a wiring duct connected to a commercial power source, by power supply from the power supply device 20. If the wiring duct 45c includes a control terminal for transmitting a second control signal, the lighting device 50c can also be controlled by the second control signal output by the signal conversion circuit 44.

[0039] In Fig. 5, the input unit 41 is provided on an end surface (longitudinal end) of the adapter body 46c, but as shown in Fig. 6, it may be provided on the upper surface of the adapter body 46c. Fig. 6 is a diagram showing a modified example of the arrangement of the input unit 41. In this way, the arrangement of the input unit 41 is not particularly limited.

[0040] In addition, in Fig. 5, the adaptor body 46c is connected to the end face (longitudinal end) of the wiring duct 45c, but as shown in Fig. 7, it may be provided on the upper surface of the wiring duct 45c. Fig. 7 is a diagram showing a modified example of the arrangement of the adaptor body 46c. In this way, the arrangement of the adaptor body 46c is not particularly limited.

[0041] The adapter 40c can also operate devices other than the lighting device 50c that can be connected to the wiring duct 45c by using power supplied from the power supply device 20. Examples of other devices that can be connected to the wiring duct 45c include a camera, an audio device (speaker), a video device, a disaster prevention device, a sensor, a wireless LAN router, and a Bluetooth (registered trademark) module.

[0042] [Adapter example 4] Next, a fourth concrete example of the adapter 40 will be described. FIG.

[0043] The adapter 40d shown in FIG. 8 has, as the connection structure 45, a plug 45d (sometimes called a socket or the like) connected to a wiring duct 80 separate from the adapter 40d. The wiring duct 80 is not connected to other power sources such as a commercial power source. When the plug 45d is connected to the wiring duct 80, the power conversion circuit 43 included in the adapter 40d can supply power to a device (such as the above-mentioned lighting device 50c) that can be connected to the wiring duct 80 via the wiring duct 80. That is, the adapter 40d can operate a device that can be connected to the wiring duct 80 by power supply from the power supply device 20. When the plug 45d and the wiring duct 80 include a control terminal for transmitting a second control signal, the device that can be connected to the wiring duct 80 can also be controlled by the second control signal output by the signal conversion circuit 44.

[0044] [Adapter Variation 1] Note that not only the first control signal and power output by the power supply device 20, but also AC power output by a commercial power source and a control signal output by an external device may be input to the adapter 40. Fig. 9 is a block diagram showing a functional configuration of such an adapter according to the first modification.

[0045] An adaptor 40e according to the first modification includes a first input portion 41e, a second input portion 42e, an internal circuit 43e, and a connection structure 45e.

[0046] The first input unit 41e has a connection structure to which the standard cable 70 is connected, and is specifically an RJ-45 type connector. The first input unit 41e receives DC power of 36-57 V and a first control signal from the power supply device 20.

[0047] The second input unit 42e has an arbitrary connection structure different from that of the first input unit 41e. The second input unit 42e includes an AC terminal to which 100-242V AC power is input, a control terminal to which a control signal output by an external device is input, and a ground terminal.

[0048] The internal circuit 43e includes a PoE conversion circuit, a signal conversion circuit, a PD interface, and a power conversion circuit.

[0049] The connection structure 45e is an arbitrary connection structure different from the first input unit 41e. The connection structure 45e includes a power supply terminal to which the power processed by the internal circuit 43e is output, a control terminal to which the second control signal processed by the internal circuit 43e is output, and a ground terminal. As a specific structure (mechanical structure) of the connection structure 45e, for example, any of the connection structures included in the adapters 40a to 40d described in the above embodiment is adopted.

[0050] First, the process of the internal circuit 43e when the power supply device 20 is connected to the first input unit 41e will be described. The PoE conversion circuit outputs a first control signal to the signal conversion circuit, and outputs 36-57V DC power to the PD interface. The signal conversion circuit converts the first control signal to a second control signal, and outputs it to the control terminal of the connection structure 45e. The PD interface outputs the 36-57V DC power as it is to the power supply terminal of the connection structure 45e.

[0051] As a result, when the power supply device 20 is connected to the first input section 41e, DC power of 36-57 V is output to the power terminal of the connection structure 45e, and a second control signal (such as a PWM signal or a control signal compliant with DALI (registered trademark)) is output to the control terminal of the connection structure 45e.

[0052] Next, the processing of the internal circuit 43e when a commercial power source and an external device are connected to the second input unit 42e will be described. The power conversion circuit is, for example, an AC / DC buck converter, which converts 100-242V AC power input to the AC terminal of the second input unit 42e into 36-57V DC power and outputs it to the power supply terminal of the connection structure 45e. A second control signal is input from the external device to the control terminal of the second input unit 42e, and the second control signal is output as is to the control terminal of the connection structure 45e.

[0053] In this way, the adapter 40e can output 36-57V DC power and the second control signal both when the power supply device 20 is connected to the first input portion 41e and when the commercial power source and the external device are connected to the second input portion 42e. In other words, the connection structure 45e can supply both power based on DC power and power based on AC power to the device connected to the connection structure 45e.

[0054] [Adapter Variation 2] 10 is a block diagram showing a functional configuration of an adapter according to Modification 2. An adapter 40f according to Modification 2 includes a first input unit 41e, a second input unit 42e, an internal circuit 43f, and a connection structure 45e.

[0055] The internal circuit 43f includes a PoE conversion circuit, a first signal conversion circuit, a PD interface, a power conversion circuit, and a second signal conversion circuit.

[0056] First, the process of the internal circuit 43f when the power supply device 20 is connected to the first input unit 41e will be described. The PoE conversion circuit outputs a first control signal to the first signal conversion circuit, and outputs 36-57V DC power to the PD interface. The first signal conversion circuit converts the first control signal to a second control signal and outputs it to a control terminal of the connection structure 45e. The PD interface outputs the 36-57V DC power as it is to the power conversion circuit. The power conversion circuit is, for example, a DC / DC boost converter, and converts the 36-57V DC power to 141-342V DC power and outputs it to the power supply terminal of the connection structure 45e.

[0057] As a result, when the power supply device 20 is connected to the first input section 41e, DC power of 141-342V is output to the power supply terminal of the connection structure 45e, and a second control signal is output to the control terminal of the connection structure 45e.

[0058] Next, the process of the internal circuit 43f when a commercial power source and an external device are connected to the second input unit 42e will be described. 100-242V AC power is input from the commercial power source to the AC terminal of the second input unit 42e, and the 100-242V AC power is output as is to the power terminal of the connection structure 45e. The second signal conversion circuit converts any control signal input to the control terminal of the second input unit 42e into a second control signal and outputs it to the control terminal of the connection structure 45e.

[0059] In this way, when the power supply device 20 is connected to the first input portion 41e, the adapter 40f can output DC power of 141-342 V to the power supply terminal of the connection structure 45e, and when a commercial power source is connected to the second input portion 42e, can output AC power of 100-242 V to the power supply terminal of the connection structure 45e. In other words, the connection structure 45e can supply both power based on DC power and power based on AC power to a device connected to the connection structure 45e.

[0060] In addition, the adapter 40f can output a second control signal to the control terminal of the connection structure 45e both when the power supply device 20 is connected to the first input portion 41e and when a commercial power source and an external device are connected to the second input portion 42e.

[0061] [Adapter Variation 3] 11 is a block diagram showing a functional configuration of an adapter according to Modification 3. An adapter 40g according to Modification 3 includes a first input unit 41e, a second input unit 42e, an internal circuit 43g, and a connection structure 45e.

[0062] The internal circuit 43g includes a PoE conversion circuit, a first signal conversion circuit, a PD interface, a power conversion circuit, and a second signal conversion circuit.

[0063] First, the process of the internal circuit 43g when the power supply device 20 is connected to the first input unit 41e will be described. The PoE conversion circuit outputs a first control signal to the first signal conversion circuit, and outputs 36-57V DC power to the PD interface. The first signal conversion circuit converts the first control signal to a second control signal and outputs it to the control terminal of the connection structure 45e. The PD interface outputs the 36-57V DC power as it is to the power conversion circuit. The power conversion circuit converts the 36-57V DC power to 36-342V DC power and outputs it to the power supply terminal of the connection structure 45e.

[0064] As a result, when the power supply device 20 is connected to the first input section 41e, DC power of 36-342V is output to the power supply terminal of the connection structure 45e, and a second control signal is output to the control terminal of the connection structure 45e.

[0065] Next, the process of the internal circuit 43g when a commercial power source and an external device are connected to the second input unit 42e will be described. The power conversion circuit converts 100-242V AC power input to the AC terminal of the second input unit 42e into 36-342V DC power and outputs it to the power supply terminal of the connection structure 45e. The second signal conversion circuit converts any control signal input to the control terminal of the second input unit 42e into a second control signal and outputs it to the control terminal of the connection structure 45e.

[0066] In this way, the adapter 40g can output 36-342V DC power and the second control signal both when the power supply device 20 is connected to the first input portion 41e and when the commercial power source and the external device are connected to the second input portion 42e. In other words, the connection structure 45e can supply both power based on DC power and power based on AC power to the device connected to the connection structure 45e.

[0067] [Effects, etc.] As described above, the device control system 10 includes a power supply device 20 having a plurality of connection ports 21, and an adapter 40 connected to one of the plurality of connection ports 21 via a standard cable 70 and receiving power supply from the power supply device 20 via the standard cable 70. The adapter 40 has a connection structure 45 for supplying power to a device, and causes the device connected to the connection structure 45 to operate as a power receiving device. The standard cable 70 is an example of a first cable.

[0068] By including the adapter 40, such a device control system 10 can control devices that cannot be connected to the power supply device 20.

[0069] For example, the adapter 40 further includes a power conversion circuit 43 that converts the power supplied from the power supply device 20 via the standard cable 70. The connection structure 45 is for supplying the power obtained by the above conversion to the device.

[0070] By including the adapter 40, such a device control system 10 can control devices that cannot be controlled using the power supplied by the power supply device 20.

[0071] For example, the adapter 40 further includes a signal conversion circuit 44 that converts a first control signal received by the adapter 40 from the power supply device 20 via the standard cable 70 into a second control signal. The connection structure 45 is for outputting the second control signal to the device.

[0072] By including the adapter 40, such a device control system 10 can control a device that cannot be controlled based on the first control signal output by the power supply device 20.

[0073] Also, for example, the connection structure 45 is a quick-connect terminal 45a into which the cable 71 is inserted, and the connection structure 45 (quick-connect terminal 45a) is connected to an apparatus (lighting apparatus 50a) via the cable 71.
