In the following, similar elements will be described with the same reference numerals in all drawings.

[First Embodiment]
FIG. 1 is a block diagram showing a configuration of an example of the effect lighting system 1 according to the embodiment. FIG. 2 is a block diagram showing a configuration of a signal conversion device 30 constituting the effect lighting system 1.

The effect lighting system 1 according to the present embodiment is a lighting control system used in, for example, a stage, a studio, a hall, or the like, and performs a lighting effect by dimming control of a lighting fixture. The effect lighting system 1 shown in FIG. 1 includes a dimming control console 10, a dimmer 20, a signal conversion device (control device) 30, and an LED lighting fixture 40.

The dimming control console 10 outputs a control signal for controlling a dimming state such as on / off control for switching the lighting / extinguishing of the LED lighting fixture 40 and changing the light amount of the LED lighting fixture 40 to the dimming board 20. The dimming control console 10 is provided with an operation panel (not shown) in which controls such as switches and faders corresponding to the LED lighting fixtures 40 are arranged. The dimming control console 10 generates a control signal according to the operation contents of the operator, for example, an on / off operation of a switch or the like or a dimming operation of a fader or the like, and outputs the control signal to the dimmer board 20 via the signal line L1. Examples of the control signal output by the dimming control console 10 include a DMX signal, but the control signal is not particularly limited. By operating each operator of the dimming control console 10, the user can turn on / off the LED lighting fixture 40, adjust the dimming level, and the like.

The dimmer 20 is configured to generate a phase control signal according to the input control signal and output it to the signal conversion device 30 via the signal line L2. That is, the dimmer 20 controls the dimming state of the LED lighting fixture 40 by changing the amount of power supplied when supplying power supplied from an external power source (not shown). Therefore, the number of phase control signals output by the dimmer 20 is only one for one signal line L2. In FIG. 1, only one LED lighting fixture 40 is shown for one signal line L2, but a plurality of LED lighting fixtures 40 are connected to one signal conversion device 30 and the same phase control signal is displayed. Dimming control may be performed collectively according to the above.

Further, although FIG. 1 shows only one signal line L2 connected to the dimmer 20, the number and types of the LED lighting fixtures 40 dimmed and controlled by the dimmer 20 in the effect lighting system 1 are shown. , Can be set arbitrarily. For example, as will be described in detail in the second embodiment, a plurality of phase control signals are transmitted to the signal conversion device 30, and dimming control is independently performed on the LED lighting fixture 40 that differs depending on each phase control signal. You may.

The signal conversion device 30 is configured to input the phase control signal output from the dimmer 20, convert it into a DMX control signal, and output it to the LED lighting fixture 40. In other words, the signal conversion device 30 creates a DMX control signal that performs the same dimming control as the input phase control signal, and outputs the DMX control signal to the LED luminaire 40.

The DMX (Digital Multiplex) signal is a signal based on a communication protocol such as the DMX512 / 1990 standard and the DMX512-A standard, and is well known as a standardized control signal in the fields of lighting equipment, production equipment, and the like. Since the DMX signal has 512 channels and can transmit data for a maximum of 512 serially, it is possible to control a large number of light sources individually and simultaneously.

The signal conversion device 30 shown in FIG. 2 includes a reception unit 32, a signal control unit 34, a transmission unit 36, and a storage unit 38. The signal control unit 34 is connected to the signal line L2 for transmitting the phase control signal via the reception unit 32, and is connected to the signal line L3 for transmitting the DMX control signal via the transmission unit 36. A feeder line (not shown) that receives power from the outside is connected to the signal conversion device 30, and power is supplied to the components of the signal conversion device 30 such as the signal control unit 34. The signal conversion device 30 is attached to, for example, an installation device (not shown) such as a baton device suspended from a ceiling or the like.

The receiving unit 32 is configured to receive the phase control signal output from the dimmer 20 and transmit it to the signal control unit 34. The signal control unit 34 is configured to convert the phase control signal transmitted from the reception unit 32 into a DMX control signal. The signal control unit 34 includes, for example, a processor (arithmetic processing unit) that is configured by a microcomputer and operates according to a program as a main hardware configuration. The signal control unit 34 reads out the program, data, map, etc. stored in the storage unit 38, and executes a predetermined operation. The processor is composed of, for example, one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration).

For example, address data indicating an address associated with the LED lighting fixture 40 for dimming control, control data such as dimming data for dimming control of the LED lighting fixture 40, and the like are inserted into each channel of the DMX control signal. There is. The dimming control data included in the phase control signal is converted into dimming data corresponding to the DMX control signal by the calculation performed by the signal control unit 34. Further, the signal control unit 34 creates a DMX control signal for dimming and controlling the LED lighting fixture 40. The converted dimming data is inserted into the channel associated with the LED lighting fixture 40 that performs dimming control among the channels included in the created DMX control signal. Specifically, for example, the storage unit 38 stores in advance a map or the like in which the LED lighting fixture 40 whose dimming is controlled by the phase control signal and the address of the channel into which the dimming data is inserted are associated with each other. The signal control unit 34 reads the map or the like stored in the storage unit 38 to insert the converted dimming data into the channel having the address associated with the LED lighting fixture 40. The method of converting a phase control type signal to a DMX type signal is a well-known technique in the field of lighting control and the like according to the present disclosure, and thus the description thereof will be omitted.

The transmission unit 36 is connected to the LED lighting fixture 40 via the signal line L3, and is configured to output a DMX control signal including a dimming signal for dimming the LED lighting fixture 40.

The LED lighting fixture 40 has an LED, which is a semiconductor light emitting element, as a light source, and a dimming state or the like is controlled according to a DMX control signal. The LED lighting fixture 40 has an input terminal for inputting a DMX control signal and an output terminal for outputting a DMX control signal.

The LED lighting fixture 40 is attached to, for example, a baton device or the like. Further, a feeding line (not shown) for supplying lighting power to the LED lighting fixture 40 is connected to the LED lighting fixture 40. The power supply to the LED lighting fixture 40 may be performed, for example, by connecting the power supply line to the power supply connector provided in the baton device and passing through the baton device, or connecting the power supply line to the signal conversion device 30. Then, it may be carried out via the signal conversion device 30.

The LED lighting fixture 40 is connected to at least the signal line L3 connected to the signal conversion device 30 via an input terminal. As a result, the LED luminaire 40 inputs the DMX control signal output by the signal conversion device 30 and transmitted via the signal line L3. The LED luminaire 40 changes the dimming state such as on / off and dimming level based on the dimming data inserted in the channel associated with the LED luminaire 40 included in the input DMX control signal.

The dimming control method of the LED lighting fixture 40 by the effect lighting system 1 of the present embodiment is summarized as follows. When the dimming control console 10 performs an on / off operation by the lighting switch, a dimming level operation by the fader, or the like, the dimming control console 10 transmits a control signal to the dimmer board 20 via the signal line L1. When the dimmer 20 receives the control signal output from the dimming control console 10, the dimmer 20 transmits the phase control signal for controlling the dimming state of the LED lighting fixture 40 via the signal line L2 associated with the LED lighting fixture 40. Then, it is transmitted to the signal conversion device 30.

The signal conversion device 30 converts the control signal received by the reception unit 32 into a DMX control signal by the signal control unit 34. Then, the transmission unit 36 transmits the converted DMX control signal to the LED lighting fixture 40. In the DMX control signal transmitted from the signal conversion device 30, dimming data for performing dimming control of the LED lighting fixture 40 is inserted into a channel assigned in advance in association with the LED lighting fixture 40. The LED luminaire 40 changes the on / off or dimming level of the LED light source based on the dimming data included in the received DMX control signal. As a result, the lighting and dimming level of the LED lighting fixture 40 are controlled according to the operating state of the dimming control console 10.

As described above, the signal conversion device 30 converts the phase control signal output by the dimmer 20 into a DMX control signal while maintaining the control content of the dimming state, outputs the light to the LED lighting fixture 40, and outputs the LED lighting. The fixture 40 can be dimmed and controlled. When such a signal conversion device 30 is used, when introducing an LED lighting fixture into an existing production lighting system using a halogen lighting fixture or the like, no major system modification is required. That is, in the existing production lighting system, it is possible to introduce the LED lighting fixture in place of the halogen lighting fixture or the like by a simple method using the existing facility.

FIG. 6 shows an example of the effect lighting system 100 that dimmes and controls the halogen luminaire 60 by the phase control signal. In the effect lighting system 100 shown in FIG. 6, a feed line is connected from the dimmer 20 to the halogen luminaire 60, and the feed amount is adjusted by phase control to control the on / off and dimming level of the halogen luminaire 60. Will be done. In the effect lighting system 100 shown in FIG. 6, the effect lighting system 1 shown in FIG. 1 can be constructed by using the signal conversion device 30 and the LED lighting device 40 of the present embodiment in place of the halogen lighting device 60. ..

More specifically, in the effect lighting system 100 shown in FIG. 6, the halogen lighting device 60 suspended from the baton device is replaced with the LED lighting device 40, and the above-mentioned signal conversion device 30 is suspended from the same baton device. Then, the signal line (feeding line) L2 connected to the halogen lighting fixture 60 is connected to the signal conversion device 30, and the LED lighting fixture 40 and the signal conversion device 30 are connected by a signal line capable of transmitting the DMX signal. Then, a power supply line is separately connected to the LED lighting fixture 40 and the signal conversion device 30. By additionally installing the control device at the place where the lighting fixture is installed in this way, it is possible to change to the effect lighting system 1 of the present embodiment, which enables the dimming control of the LED lighting fixture by the same dimming operation.

As mentioned above, in order to introduce LED lighting fixtures in place of halogen lighting fixtures in the conventional production lighting system, it was considered necessary to make major system modifications such as re-laying signal lines and removing dimmers. .. Therefore, LED lighting fixtures are often introduced when new construction or renovation work is carried out on stages and halls equipped with a directing lighting system, and the introduction of LED lighting fixtures into existing directing lighting systems has progressed too much. There is a current situation that was not there. On the other hand, in the production lighting system 1 of the present embodiment, by using the above signal conversion device 30 together with the LED lighting fixture 40, the halogen lighting fixture can be converted into a halogen lighting fixture only by changing the installation of the above-mentioned very small fixture. Instead, it becomes possible to introduce the LED lighting fixture 40.

The effect lighting system 1 shown in FIG. 1 shows a mode in which one LED lighting fixture 40 is connected to one signal conversion device 30. However, in the effect lighting system 1 according to the present embodiment, the number and type of the LED lighting fixtures 40 for dimming control by the DMX control signal output by the signal conversion device 30 can be arbitrarily set. For example, by connecting the output terminal of one LED luminaire and the input terminal of another LED luminaire with a signal line capable of transmitting DMX signals, and connecting only the most upstream LED luminaire to the signal converter. , Connect multiple LED luminaires serially (daisy chain). Then, the plurality of connected LED lighting fixtures are set to be dimmed and controlled based on the dimming data inserted in the same channel. As a result, a plurality of LED lighting fixtures can be associated with one phase control signal output by the dimmer 20 and collectively controlled (so-called group control) by one fader operation or the like.

The dimming control console 10 generates a control signal according to the operation content of the operator and outputs the control signal to the dimmer board 20 via the signal line L1. The dimmer 20 generates a phase control signal according to the input control signal, and converts the phase control signal into a signal conversion device via signal lines L21 to L24 associated with each of the LED lighting fixtures 41 to 44. It is configured to output to 50.

The signal conversion device 50 inputs the phase control signal output from the dimmer 20 via the signal lines L21, L22, L23 and L24, converts it into a DMX control signal, and converts the LED lighting fixtures 41, 42, 43 and 44. It is configured to output to. At this time, in the signal conversion device 50, the dimming control information included in the phase control signals received from each of the signal lines L21 to L24 is associated with each of the LED lighting fixtures 41 to 44 in the converted DMX control signal. It is configured to be inserted into different channels.

A mode of conversion from the phase control signal to the DMX control signal performed by the signal conversion device 50 will be described with reference to FIG. The signal conversion device 50 shown in FIG. 4 includes a reception unit 32, a signal control unit 34, a transmission unit 36, and a storage unit 38. The receiving unit 32 is connected to the signal lines L21 to L24, receives the phase control signal output from the dimmer 20 for dimming control for each of the LED lighting fixtures 41 to 44, and transmits the phase control signal to the signal control unit 34. It is configured as follows.

The signal control unit 34 performs an operation to convert the dimming control data included in each phase control signal into dimming data corresponding to the DMX control signal for each signal line L21 to L24 in which the phase control signal is transmitted. Further, the signal control unit 34 creates a DMX control signal for dimming and controlling the LED lighting fixtures 41 to 44. The converted dimming data is inserted into the channel included in the created DMX control signal. At this time, each dimming data based on the signal lines L21 to L24 is inserted into different channels associated with the LED lighting fixtures 41 to 44 that perform dimming control. Specifically, for example, the storage unit 38 stores in advance a map or the like associated with the signal lines L21 to L24, the LED lighting fixtures 41 to 44, and the address of the channel into which the dimming data is inserted. By reading out the map or the like stored in the storage unit 38, the signal control unit 34 converts the dimming data into channels having addresses associated with the signal lines L21 to L24 and the LED lighting fixtures 41 to 44. To insert. In this way, the DMX control signal in which the dimming data is inserted into different addresses for each of the LED lighting fixtures 41 to 44 is transmitted from the transmission unit 36 of the signal conversion device 50 to the LED lighting fixtures 41 to 44.

For example, the LED lighting fixtures 41 to 44 attached to the baton device or the like are serially connected to the signal conversion device 50 as described above, and are output by the signal conversion device 50 and transmitted via the signal line L3 for DMX control.

As long as the channels into which the dimming data are inserted are independent of each other, the positions of the input terminals of the signal conversion devices 50 connected to the signal lines L21 to L24 and the order of arrangement of the LED lighting fixtures 41 to 44 do not matter. , Can be set arbitrarily. In the DMX control signal, the channel assignment of the dimming data associated with each of the LED lighting fixtures 41 to 44 can be changed as appropriate, so that each operator of the dimming console 10 and the LED lighting fixtures 41 to 44 can be changed as appropriate. It has the advantage that the correspondence between the above can be arbitrarily selected.

The dimming control methods of the LED lighting fixtures 41 to 44 by the effect lighting system 2 of the present embodiment are summarized as follows. When the dimming operation table 10 performs a dimming operation such as an on / off operation by a lighting switch or a dimming level operation by a fader for each of the LED lighting fixtures 41 to 44, the dimming operation table 10 outputs a control signal. It is transmitted to the dimmer 20 via the signal line L1. Upon receiving the control signal output from the dimming control console 10, the dimmer 20 transmits the phase control signal for controlling the dimming state to the signal lines L21 to L24 associated with each of the LED lighting fixtures 41 to 44.

It can be changed to a production lighting system that can control dimming. Therefore, when the signal conversion device 50 is used, when the LED lighting fixture is introduced into the production lighting system using a plurality of halogen lighting fixtures whose dimming is controlled by different phase control signals, the signal line is re-laid, the light board is removed, and the like. Does not require major system refurbishment. That is, in the existing production lighting system, the LED lighting fixture can be introduced in place of the halogen lighting fixture or the like by a simple method using the existing facility.

The color LED luminaire 45 includes four color LED light sources of red, green, blue, and white that can be dimmed and controlled independently of each other.

The effect lighting system 3 of the present embodiment shown in FIG. 5 and the effect lighting system 2 of the second embodiment shown in FIG. 3 have four independent light sources instead of the four LED lighting fixtures 41 to 44. The difference is that the color LED luminaire 45 capable of dimming control is provided. However, the present embodiment and the second embodiment are different from the present embodiment and the second embodiment, except that each signal associated with the four LED lighting fixtures 41 to 44 is associated with the four color light sources included in the color LED lighting fixture 45. Have substantially the same configuration. Therefore, in the effect lighting system 3 of the present embodiment, the conversion of the phase control signal to the DMX control signal by the signal conversion device 50 and the dimming control of the color LED lighting fixture 45 are also the same as those of the second embodiment described above. It can be done in a similar way.

That is, when the dimming operation for each light source is performed on the dimming control console 10, the dimming control console 10 transmits a control signal to the dimmer 20 via the signal line L1. When the dimmer 20 receives the control signal output from the dimming control console 10, the dimmer 20 transmits the phase control signal for controlling the dimming state to the signal conversion device via the signal lines L21 to L24 associated with each light source. Send to 50. The signal conversion device 50 converts the received control signal into a DMX control signal and transmits it to the color LED lighting fixture 45. The color LED luminaire 45 changes the on / off or dimming level of each light source based on the dimming data included in the channel assigned to each light source of the received DMX control signal. In this way, each light source of the color LED lighting fixture 45 is controlled in lighting and dimming level according to the operating state of the dimming control console 10.

FIG. 8 shows a conventional effect lighting system 102 that uses a halogen lamp to illuminate four colors of red, green, blue, and white. The effect lighting system 102 shown in FIG. 8 includes a dimming control console 10 and a dimming board 20, and further includes halogen lighting fixtures 71 to 73 having red, green, and blue color filters as lighting fixtures, and a color filter. It includes a (white) halogen luminaire 74 that does not exist. The dimmer 20 is connected to the halogen luminaires 71 to 74 via signal lines L21 to L24, respectively. As a result, in the effect lighting system 102, the dimming control of the halogen lighting fixtures 71 to 74 exhibiting the respective colors of red, green, blue, and white is performed independently of each other by the dimming control console 10 and the dimming board 20. .. In such an effect lighting system 3, the effect lighting system 3 shown in FIG. 5 can be constructed by using the signal conversion device 50 and the color LED lighting equipment 45 of the present embodiment in place of the halogen lighting fixtures 71 to 74. can.

For example, in the effect lighting system 102 shown in FIG. 8, it is assumed that the halogen lighting fixtures 71 to 74 are suspended from the baton device. In such an effect lighting system 102, each light source of the color LED lighting fixture 45 can be independently dimmed and controlled by the same dimming operation only by changing or adding a device suspended from the baton device. Can be changed to a lighting system. Therefore, by using the signal conversion device 50, when the LED lighting fixture is introduced into the conventional production lighting system in which the halogen lighting fixture is individually provided for each color, the signal line is re-laid and the dimmer is removed. No need for system modification. That is, in the existing production lighting system, the LED lighting fixture can be introduced in place of the halogen lighting fixture or the like by a simple method using the existing facility. Moreover, by using a color LED luminaire having a plurality of types of light sources exhibiting different colors, it is sufficient to install a single LED luminaire, and it is not necessary to prepare a halogen luminaire for each color, and each color. It is possible to control dimming independently for each.

In the above description, the effect lighting system 3 of the present embodiment is shown by taking as an example a case where each light source of the color LED lighting fixture 45 having four color light sources is dimmed and controlled. However, in the effect lighting system 3 of the present embodiment, the LED lighting fixture may have two types, three types, or five or more types of light sources exhibiting different colors. Further, the number of color LED lighting fixtures having a plurality of color light sources can be arbitrarily set.

The present disclosure is not limited to each of the above embodiments, and various improvements and changes can be made within the scope of the claims of the present application and the equivalent scope thereof.

In each of the above embodiments, a directing lighting system including only LED lighting fixtures as a lighting fixture has been described as an example, but in the directing lighting system, both LED lighting fixtures and halogen lighting fixtures are provided, and these may be used at the same time. good. As a result, the existing phase control type directing lighting system can be used as it is, and the LED lighting fixture and the halogen lighting fixture can be used properly depending on the scene, and it is possible to perform a lighting directing that makes the best use of the advantages of both.

Further, the dimming control by the effect lighting system is not limited to the on / off and dimming level of the LED lighting fixture, and any conventional one that can be controlled by the phase control signal can be performed. In the effect lighting system of the present disclosure, for example, it is possible to control the irradiation angle (pan and tilt), focal length, design (gobo), etc. in the LED lighting equipment.
