FIG. 1 is a block diagram schematically illustrating a lighting control system and a lighting fixture according to the embodiment.
As illustrated in FIG. 1, the lighting control system 2 includes a plurality of lighting fixtures 10 and a control device 12. The control device 12 is connected to each lighting fixture 10. The control device 12 transmits a control signal 20 to each lighting fixture 10. Each luminaire 10 emits light of a predetermined illuminance and color based on a control signal 20 from the control device 12. As described above, the illumination control system 2 controls the light irradiation of each lighting fixture 10 by transmitting the control signal 20 from the control device 12 to each lighting fixture 10. For example, the lighting control system 2 performs lighting effects such as a studio or a stage by controlling the lighting and turning off of each lighting fixture 10 and the illuminance and color of the light emitted from each lighting fixture 10.

  Each lighting fixture 10 and the control apparatus 12 perform communication based on communication standards, such as DMX standard and RDM (Remote Device Management) standard, for example. For example, when performing communication based on the DMX standard or the RDM standard, each lighting fixture 10 and the control device 12 are, for example, daisy chain connected (series connection), and the control signal 20 is sequentially transmitted from the control device 12 to the subsequent lighting fixture 10. introduce.

  The control signal 20 includes, for example, control information 22 for each of the plurality of lighting fixtures 10. Each control information 22 contains the identification information 24 for identifying the some lighting fixture 10, for example. The identification information 24 is, for example, a control address set in advance for each lighting fixture 10. Moreover, each control information 22 contains information, such as lighting of the corresponding lighting fixture 10, light extinction, the illumination intensity of a light, and a color, for example. Each luminaire 10 reads its own control information 22 from the control signal 20 based on the identification information 24 and irradiates light based on the read control information 22. However, the information included in the control signal 20 and the control information 22 is not limited to the above, but may be any information corresponding to the communication standard.

  However, the communication method between each lighting fixture 10 and the control device 12 is not limited to the DMX standard or the RDM standard, and any communication method may be used. The connection form between each lighting fixture 10 and the control device 12 may be any form according to the communication method. Communication between each lighting fixture 10 and the control device 12 is not limited to wired communication, and may include wireless communication. In other words, each lighting fixture 10 and the control device 12 are not limited to those connected by wires, but may include those connected via wireless. The lighting control system 2 is not limited to a lighting effect such as a studio or a stage, and may be any system that controls at least lighting and extinguishing of each lighting fixture 10.

  The luminaire 10 includes a light source unit 40, a lighting circuit 42, a control unit 44, a communication unit 46, a detection unit 48, and a power supply unit 50. The power supply unit 50 is connected to each of the lighting circuit 42, the control unit 44, and the communication unit 46. The power supply unit 50 is connected to a power source such as a commercial power supply, for example. The power supply unit 50 converts the power supplied from the power source into power corresponding to each unit, and supplies the converted power to each unit. Each part of the luminaire 10 operates in response to power supply from the power supply unit 50.

  The light source unit 40 emits light. The light source unit 40 includes, for example, a light emitting diode 40a as a light source. The light source unit 40 includes, for example, a plurality of light emitting diodes 40a. In other words, the light source unit 40 is an LED lamp. However, the light source of the light source unit 40 is not limited to a light emitting diode, and may be a light bulb, a discharge tube, or the like.

  The communication unit 46 communicates with the control device 12 and the other lighting fixtures 10. The communication unit 46 includes, for example, an input unit 46 a for inputting the control signal 20 from the control device 12 or the front stage lighting fixture 10, and an output unit 46 b for transmitting the input control signal 20 to the rear stage lighting fixture 10. And having.

  For example, the communication unit 46 inputs the control signal 20 input from the input unit 46a to the control unit 44, and outputs the control signal 20 output from the control unit 44 from the output unit 46b. Alternatively, the control signal 20 input from the input unit 46a is input to the control unit 44 and output from the output unit 46b. As a result, the control signal 20 input from the control device 12 or the front lighting apparatus 10 is transmitted to the rear lighting apparatus 10.

  The control unit 44 reads its own control information 22 from the control signal 20 based on the identification information 24, and controls light irradiation from the light source unit 40 based on the read control information 22. For example, the control unit 44 generates a drive signal corresponding to the control signal 20 and inputs the generated drive signal to the lighting circuit 42. The lighting circuit 42 converts the power supplied from the power supply unit 50 into power corresponding to the drive signal, and supplies the converted power to the light source unit 40. Thereby, the light irradiated from the light source unit 40 can be controlled to the illuminance, color, or the like corresponding to the control information 22.

  In addition, the control unit 44 detects an abnormality related to the irradiation of light from the light source unit 40, and executes control to turn on another lighting fixture 10 based on the control information 22 when the abnormality is detected.

  The detection unit 48 performs predetermined detection related to a failure of at least one of the light source unit 40 and the lighting circuit 42 and inputs a detection result to the control unit 44. The control unit 44 determines the failure of the light source unit 40 and the lighting circuit 42 based on the detection result of the detection unit 48, and executes control to turn on another lighting fixture 10 when it is determined that the failure has occurred. .

  For example, the detection unit 48 detects at least one of a current flowing through the light source unit 40 or a voltage applied to the light source unit 40. Based on the detection result of the detection unit 48, the control unit 44 determines whether or not the current flowing through the light source unit 40 or the applied voltage is a desired value based on the control information 22, and sets the desired value. If not, it is determined that at least one of the light source unit 40 and the lighting circuit 42 has failed. The abnormality of the light source unit 40 or the lighting circuit 42 may be determined in consideration of the current flowing through the light source unit 40 and the applied voltage.

  However, the detection of the detection unit 48 is not limited to the above, and any detection that can detect a failure of at least one of the light source unit 40 and the lighting circuit 42 may be used. The abnormality detected by the control unit 44 is not limited to the failure of at least one of the light source unit 40 and the lighting circuit 42, and may be any abnormality that makes it impossible to irradiate appropriate light from the light source unit 40.

FIG. 2 is a flowchart schematically illustrating operations of the illumination control system and the lighting fixture according to the embodiment.
As shown in FIG. 2, in the lighting fixture 10, the control signal 20 is input from the control device 12 or the preceding lighting fixture 10 (step S <b> 101 in FIG. 2).

  When the control signal 20 is input to the input unit 46a, the communication unit 46 of the luminaire 10 inputs the control signal 20 to the control unit 44 and outputs the control signal 20 as it is from the output unit 46b. It transmits to the lighting fixture 10 (step S102 of FIG. 2).

  When the control signal 20 is input from the communication unit 46, the control unit 44 reads out its own control information 22 from the control signal 20 based on the identification information 24 (step S103 in FIG. 2).

  When the control unit 44 reads the control information 22, the control unit 44 controls light irradiation from the light source unit 40 based on the control information 22, and emits light corresponding to the control information 22 at a timing corresponding to the control information 22. 40 is irradiated (step S104 in FIG. 2).

  After starting the light irradiation from the light source unit 40, the control unit 44 detects an abnormality related to the light irradiation from the light source unit 40 based on the detection result of the detection unit 48 (step S105 in FIG. 2). . If no abnormality is detected, the control unit 44 returns to the operation of step S101 and controls the irradiation of light from the light source unit 40 based on the control signal 20 input from the control device 12 or the front lighting fixture 10. To do. As a result, the lighting, extinction, illuminance, color, and the like of the light emitted from the lighting fixture 10 are controlled based on the control signal 20, and an illumination effect or the like can be performed.

  On the other hand, when detecting an abnormality, the control unit 44 stops the irradiation of light from the light source unit 40 (step S106 in FIG. 2). And the control part 44 outputs own control information 22 from the output part 46b of the communication part 46, and transmits own control information 22 to the lighting fixture 10 of a back | latter stage (step S107 of FIG. 2). In addition, when the occurrence of an abnormality is known in advance before the light source unit 40 is turned on, the control information 22 is transmitted without the light source unit 40 being turned on after the control information 22 is read. Also good.

  When the control information 22 is input from the front lighting apparatus 10, the control unit 44 of the rear lighting apparatus 10 determines whether or not lighting is possible (step S <b> 108 in FIG. 2). That is, the control unit 44 determines whether or not the control unit 44 is lit based on the control signal 20 from the control device 12.

  When it is determined that the control unit 44 is not lit but can be lit, the control unit 44 controls the irradiation of light from the light source unit 40 based on the input control information 22 of the previous stage lighting fixture 10, and the control information At a timing corresponding to 22, light corresponding to the control information 22 is emitted from the light source unit 40 (step S109 in FIG. 2).

  On the other hand, the control unit 44 outputs the control information 22 of the input front stage luminaire 10 from the output unit 46b of the communication unit 46 when it is determined that the control unit 44 is lit or may be lit. Then, the control information 22 is further transmitted to the subsequent lighting apparatus 10.

  Hereinafter, by repeating the same operation, when an abnormality occurs in any of the lighting fixtures 10, it is possible to turn on another lighting fixture 10 on the rear stage side. In other words, when an abnormality occurs in the lighting fixture 10, another lighting fixture 10 can be interlocked. For example, even when an abnormality occurs during the lighting effect, it is possible to irradiate appropriate light based on the control signal 20 as a whole of the lighting control system 2. Moreover, it is not necessary to perform communication with the control device 12, and the configuration of the illumination control system 2 can be suppressed from becoming complicated. Accordingly, it is possible to realize interlocking with another lighting apparatus 10 when an abnormality occurs with a simple configuration.

FIG. 3 is a flowchart schematically illustrating another operation of the lighting control system and the lighting fixture according to the embodiment.
In FIG. 3, the processing in steps S201 to S206 is substantially the same as the processing in steps S101 to S106 described with reference to FIG.
As illustrated in FIG. 3, in this example, the control unit 44 detects another abnormality and then turns on another lighting device that can be turned on based on the control information 22 of each lighting device 10 included in the control signal 20. 10 are selected (step S207 in FIG. 3). That is, the control unit 44 selects the lighting fixtures 10 that are not lit based on the control information 22.

  For example, when the lighting control system 2 performs only one-way communication to the rear side as in the DMX standard, the control unit 44 selects a lighting device that can be lit from the lighting fixtures 10 on the rear side of itself. . On the other hand, when the lighting control system 2 enables two-way communication as in the RDM standard, the control unit 44 selects a lighting device that can be turned on from the lighting devices 10 including the rear side and the front side.

  After selecting another lighting fixture 10 that can be turned on, the control unit 44 converts the control information 22 included in the control signal 20 into the control information 22 of another lighting fixture 10 that has been selected, thereby controlling the control signal 20. Is converted (step S208 in FIG. 3). In other words, the control unit 44 converts the control signal 20 by changing the identification information 24 included in its own control information 22 to the identification information 24 of the selected lighting fixture 10.

  The control unit 44 outputs the converted control signal 20 from the output unit 46b of the communication unit 46, and transmits the control signal 20 to another selected lighting fixture 10 (step S209 in FIG. 3). The converted control signal 20 is transmitted to another selected lighting device 10 by sequentially transmitting the converted control signal 20 to the subsequent lighting device 10, for example. For example, when a transmission path or the like is formed so as to be able to communicate with a predetermined lighting fixture 10, the control after conversion is directly performed on another lighting fixture 10 selected from the lighting fixture 10 that has detected an abnormality. The signal 20 may be transmitted.

  When the control unit 44 of the other selected lighting fixture 10 receives the converted control signal 20, its control information 22 included in the input control signal 20 (of the lighting fixture 10 in which an abnormality has been detected). Light irradiation from the light source unit 40 is controlled based on the control information 22), and light corresponding to the control information 22 is emitted from the light source unit 40 at a timing corresponding to the control information 22 (step S210 in FIG. 3).

  Thus, in this example, when no abnormality is detected, the control unit 44 reads out its own control information 22 from the control signal 20 based on the identification information 24, and based on the read out own control information 22, the light source While controlling the part 40, the control signal 20 is transmitted to another lighting fixture 10 as it is.

  And when the control part 44 detects abnormality, it converts own control information 22 included in the control signal 20 into control information 22 of another selected lighting fixture 10, and the converted control signal 20 is changed to another. By transmitting to the lighting fixture 10, another lighting fixture 10 is turned on based on its own control information 22.

  As described above, the determination as to whether or not lighting is possible may be performed by the lighting fixture 10 in which an abnormality has been detected. Thereby, for example, it is not necessary to make a determination one by one on the side of another lighting fixture 10, and the load on the entire system when an abnormality occurs can be reduced.

FIG. 4 is a block diagram schematically illustrating a modification of the lighting control system and the lighting fixture according to the embodiment.
Note that components that are substantially the same in function and configuration as those in the above embodiment are given the same reference numerals, and detailed descriptions thereof are omitted.
As shown in FIG. 4, in the lighting control system 2 a, the lighting fixture 10 a further includes a storage unit 52. The storage unit 52 is connected to the control unit 44. The storage unit 52 may be incorporated in the control unit 44, for example.

  The storage unit 52 stores priority order information 54. The priority information 54 stores another lighting fixture 10a included in the lighting control system 2a and the priority to be turned on when an abnormality occurs in association with each other. The priority information 54 stores, for example, the identification information 24 of each lighting fixture 10a and the priority in association with each other.

  When the control unit 44 selects another lighting fixture 10a that can be turned on based on the control information 22 of each lighting fixture 10a included in the control signal 20, the control unit 44 stores the storage unit 52 (see step S207 in FIG. 3). Is referred to. And the control part 44 determines whether lighting is possible in an order from the lighting fixture 10a with a high priority based on the priority information 54. FIG. Thereby, the control part 44 selects the lighting fixture 10a with the highest priority which can be lighted.

  In this way, by selecting the lighting fixtures 10a having a high priority, for example, when performing lighting effects, the lighting fixtures 10a that are completely unrelated to the lighting fixture 10a in which an abnormality has occurred are turned on. This can be suppressed. Therefore, the illumination control system 2a as a whole can emit more appropriate light based on the control signal 20.

  For example, when there is no lighting fixture 10a with a priority higher than a predetermined level among the other lighting fixtures 10a that can be turned on, the other lighting fixture 10a may not be turned on. In other words, when there is no lighting fixture 10a with a priority order higher than a predetermined level among the other lighting fixtures 10a that can be turned on, another lighting fixture 10a may not be selected.

FIG. 5 is a block diagram schematically illustrating a modification of the lighting control system and the lighting fixture according to the embodiment.
As shown in FIG. 5, in the lighting control system 2b, the communication unit 46 of the lighting fixture 10b includes a first output unit 46b and a second output unit 46c. The first output unit 46b is an output unit for outputting the control signal 20 as it is. The 2nd output part 46c is an output part for transmitting own control information 22 to another lighting fixture 10b, when abnormality is detected.

  When the control unit 44 detects an abnormality, the control unit 44 outputs its own control information 22 from the second output unit 46c of the communication unit 46, and transmits its own control information 22 to another lighting apparatus 10b, thereby Based on the control information 22, another lighting apparatus 10 b is turned on. The transmission of the control information 22 from the second output unit 46c may be performed by outputting only the control information 22 or may be performed by outputting the control signal 20 obtained by converting the control information 22.

  Thus, you may determine previously the lighting fixture 10b lighted when abnormality is detected. Thereby, even when abnormality occurs, more appropriate light based on the control signal 20 can be irradiated as a whole of the illumination control system 2b. Further, it is possible to save the trouble of selecting the lighting device 10b to be lit by the control unit 44, and the configuration of the control unit 44 can be further simplified.

  Further, for example, when no abnormality is detected, the control unit 44 can output the control signal 20 as it is to the second output unit 46c. Thereby, when abnormality is not detected, the lighting fixture 10b connected to the 2nd output part 46c can be operated based on the control signal 20. FIG.

FIG. 6 is a block diagram schematically illustrating a modification of the lighting control system and the lighting fixture according to the embodiment.
As shown in FIG. 6, in the lighting control system 2 c, the lighting fixture 10 c further includes an external contact 60 for connecting a non-compliant lighting fixture 14 that does not correspond to the control signal 20. In other words, the lighting fixture 14 is a lighting fixture that does not conform to a communication standard such as the DMX standard or the RDM standard.

  The control unit 44 can turn on the non-corresponding lighting fixture 14 based on the control information 22 when an abnormality is detected. The external contact 60 may be a signal line contact for inputting a signal to light the non-compliant lighting fixture 14 or a power line contact for lighting the non-compliant lighting fixture 14 by supplying power. Etc.

  Also in this example, as described above, even when an abnormality occurs, the illumination control system 2c as a whole can be irradiated with more appropriate light based on the control signal 20. Further, it is possible to save the trouble of selecting the lighting fixture 10c to be lit by the control unit 44, and the configuration of the control unit 44 can be further simplified.

  The non-corresponding lighting fixture 14 has a dimming function, for example. The control unit 44 can generate a dimming signal corresponding to the non-compliant lighting fixture 14. The dimming signal is, for example, a signal such as 0-10V dimming, 1-10V dimming, phase dimming, PWM (Pulse Width Modulation), DALI (Digital Addressable Lighting Interface).

  For example, the control unit 44 can dimm the non-compliant lighting fixture 14 by generating a dimming signal based on the control information 22 and outputting the generated dimming signal from the external contact 60. For example, when an abnormality occurs, the luminaire 14 is dimmed to illuminance based on the control information 22. Thereby, even when abnormality occurs, the light control system 2c as a whole can emit more appropriate light based on the control signal 20.

FIG. 7 is a block diagram schematically illustrating a modification of the lighting control system and the lighting fixture according to the embodiment.
As shown in FIG. 7, in the lighting control system 2 d, the external contact 60 of the lighting fixture 10 d is connected to the converter 16, and is connected to the non-compliant lighting fixture 14 via the converter 16. The control unit 44 transmits a predetermined signal based on the control information 22 to the converter 16, and converts the predetermined signal into a signal corresponding to the non-compatible lighting device 14 by the converter 16, so 14 is turned on.

  As described above, the lighting fixture 10 d may be connected to the non-compliant lighting fixture 14 via the converter 16. Thereby, for example, the types of connectable lighting fixtures 14 can be increased, and the degree of freedom of the system configuration of the lighting control system 2d can be increased.

FIG. 8 is a block diagram schematically illustrating a modification of the lighting control system and the lighting fixture according to the embodiment.
As shown in FIG. 8, in the lighting control system 2 e, the external contact 60 of the lighting fixture 10 e can connect a plurality of non-compliant lighting fixtures 14. Thus, the external contact 60 may be configured to connect a plurality of lighting fixtures 14. Thereby, the freedom degree of the system configuration | structure of the illumination control system 2e can be raised more, for example.
