Description

The present invention relates to luminaires, luminaire control methods and luminaire control programs.

Lighting control can be performed in various facilities regardless of whether it is outdoors or indoors. Outdoor lighting control can be performed, for example, in a lighting facility that lights up a public space, a structure, or the like at night. Indoor lighting control can be performed, for example, in lighting equipment such as a stage or an event venue. As the communication used for these lighting controls, for example, the unidirectional communication method DMX (Digital Multiplex) communication described in Patent Document 1 is known.

In the DMX communication described in Patent Document 1, a plurality of lighting fixtures are daisy-chained to the controller. The controller periodically outputs a DMX signal having 512 channels of DMX frames. The DMX signal transmits 1 byte, that is, 8 bits of data in each channel of the DMX frame. Each luminaire is assigned a different channel. The channel assigned to one luminaire may be a plurality of consecutive channels. The controller uses the channel assigned to each luminaire of the DMX signal to transmit data according to the control content of the corresponding luminaire.

Further, in the DMX communication described in Patent Document 1, an address indicating a channel assigned to each luminaire is set in each luminaire. When each luminaire receives the DMX signal, it acquires the data of the channel corresponding to the address set in itself, and controls its own lighting state with the control content corresponding to the data. The lighting state controlled by the luminaire can be, for example, the emission intensity, color temperature, focus, irradiation direction, etc. of the illumination light emitted by the light source for each channel of the acquired data.

Japanese Unexamined Patent Publication No. 2017-527073

In DMX communication, the DMX signal can be updated at a refresh rate of about 44 Hz. Therefore, in the lighting control by the DMX signal, the control content of the luminaire can be changed at high speed, and the illuminating by the luminaire can be dynamically changed. On the flip side, if the luminaire is unable to receive the DMX signal, it will not be able to continue the dynamic change in lighting by the luminaire. In particular, when the controller and the luminaire are wirelessly connected, there is a tendency that the luminaire cannot receive the DMX signal due to a change in the communication environment.

The present invention has been made in view of the problems of the prior art. An object of the present invention is to enable the luminaire to continue the dynamic change of lighting even if the luminaire cannot receive the DMX signal.

In order to solve the above problems, the lighting equipment according to the first aspect of the present invention includes a receiving unit that receives a DMX signal provided with a plurality of channels for transmitting lighting load control data, and the control of the DMX signal. The control is performed from an address setting unit in which a plurality of sets of continuous channels to be acquired data are set, and a continuous channel of each set of the DMX signal received by the reception unit set in the address setting unit. In a reception abnormal period in which the acquisition unit that acquires data and the reception unit cannot normally receive the DMX signal, the control of the lighting state of the lighting load of the continuous channels of each set acquired by the acquisition unit. It is provided with a transition control unit for transitioning between states corresponding to each data.

The lighting control method according to the second aspect of the present invention includes a reception step for receiving a DMX signal provided with a plurality of channels for transmitting lighting load control data, and the control for the DMX signal received in the reception step. The lighting state of the lighting load during the acquisition step of acquiring the control data from each of a plurality of sets of continuous channels for which data is acquired and the reception abnormality period during which the DMX signal cannot be normally received in the reception step. Is included in the transition control step of transitioning between the states corresponding to the control data of the continuous channels of the respective sets acquired in the acquisition step.

The lighting control program according to the third aspect of the present invention includes a reception step of receiving a DMX signal in which the computer is provided with a plurality of channels for transmitting lighting load control data, and the DMX signal received in the reception step. The lighting load during the acquisition step of acquiring the control data from a plurality of consecutive channels targeted for acquisition of the control data and the reception abnormality period during which the DMX signal cannot be normally received in the reception step. The transition control step of transitioning the lighting state of the above between the states corresponding to the control data of the continuous channels of the respective sets acquired in the acquisition step is executed.

According to the present disclosure, even if the luminaire cannot receive the DMX signal, it is possible to continue the dynamic change of the lighting by the luminaire.

Hereinafter, the present embodiment will be described with reference to the drawings. The same or equivalent parts or components are designated by the same reference numerals throughout the drawings.

The embodiments shown below exemplify an apparatus or the like for embodying the technical idea of the present invention. The technical idea of the present invention does not specify the material, shape, structure, arrangement, function, etc. of each component to the following.

As shown in FIG. 1, the lighting control system 1 of the present embodiment includes a plurality of lighting fixtures L11 to L1n, L21 to L2n, L31 to L3n, and a controller 2 for each system. This lighting control system 1 can be operated in various facilities regardless of whether it is outdoors or indoors.

The lighting fixtures L11 to L1n, L21 to L2n, and L31 to L3n (hereinafter, may be collectively referred to as lighting fixtures L) are arranged in a predetermined space according to a plurality of systems. Each luminaire L is daisy-chained to the controller 2 by a DMX signal transmission line. The transmission line may be either wired or wireless as long as it can transmit DMX signals.

The controller 2 outputs a DMX signal to each luminaire L. The DMX signal is a kind of digital dimming signal for defining the lighting state of each luminaire L. The controller 2 can transmit data according to the lighting state of the lighting fixture L, such as emission intensity, color temperature of emission color, irradiation angle of illumination light, irradiation direction, etc., to each lighting fixture L by a DMX signal. .. The frame configuration of the DMX signal will be described later.

Next, the configuration of the controller 2 and each luminaire L will be described. First, as shown in FIG. 2, the controller 2 of the present embodiment has a signal output unit 21, a timekeeping unit 22, a storage unit 23, a control unit 24, a display unit 25, a touch panel unit 26, and a display driver unit 27. There is.

The signal output unit 21 outputs a DMX signal. The DMX signal can be, for example, in a format compliant with the DMX512A communication protocol. As shown in FIG. 3, the DMX signal S is a signal in which the frame F is intermittently and repeatedly arranged with the break period B sandwiched between the DMX signal S and the previous frame F.

Here, the detailed format of the frame F of the DMX signal S will be described. The frame F has 513 slots. As shown in FIG. 4, the first slot of the frame F is assigned to the start code SC that defines the luminaire L to be controlled by the DMX signal S. Further, 512 slots other than the head of the frame F are assigned to 512 channel CHs for data transmission. Addresses 1 to 512 are assigned to each channel CH in order from the first slot side.

The DMX signal S can transmit 1 byte, that is, 8 bits of data in each of the 512 channel channels of each frame F. Each channel CH can be used for transmission of control data or the like to each luminaire L connected to the controller 2. Control data for a plurality of luminaires L can be simultaneously transmitted in one frame F.

For example, the lighting fixtures L11 to L1n for each system shown in FIG. 1 are referred to as fixture 1, the lighting fixtures L21 to L2n are referred to as fixture 2, and the lighting fixtures L31 to L3n are referred to as fixture 3, and as shown in FIG. It is assumed that the DMX signal S is transmitted to each of the lighting fixtures L of 3. In this case, in general DMX communication, control data D1 to D3 for each luminaire L is used by using channel CHs of different addresses of DMX signals S transmitted from the controller 2 to each luminaire L of the luminaires 1-3. Is sent once.

In the example shown in FIG. 4, 4-byte control data D1 is transmitted to the lighting fixture L of the fixture 1 in each channel CH of the consecutive addresses 5 to 8 of the frame F. Further, 5-byte control data D2 for the lighting fixture L of the fixture 2 is transmitted on each channel CH of the consecutive addresses 10 to 15 of the same frame F. Further, 10 bytes of control data D3 with respect to the lighting fixture L of the fixture 3 are transmitted in each channel CH of consecutive addresses 20 to 30 in the same frame F. These control data D1 to D3 are used for controlling the lighting state of each luminaire L during the normal reception period during which each luminaire L can normally receive the DMX signal S.

When conforming to the DMX512A communication protocol, the maximum refresh frequency of the DMX signal S is 44 Hz. That is, the signal output unit 21 shown in FIG. 2 can update the contents of the data transmitted in each channel CH of the DMX signal S up to 44 times per second. Therefore, each of the control data D1 to D3 can be used for controlling the lighting state of each of the lighting fixtures L during the normal reception period during which each of the lighting fixtures L of the fixtures 1 to 3 can normally receive the DMX signal.

Returning to the explanation of the configuration of the controller 2. The timekeeping unit 22 shown in FIG. 2 generates a clock pulse to measure the time. The timekeeping unit 22 can be configured by, for example, an independent IC (integrated circuit) dedicated to timekeeping. The storage unit 23 stores, for example, schedule information for lighting control of each lighting fixture L. The storage unit 23 can be configured by, for example, a non-volatile semiconductor memory element such as a flash memory.

The control unit 24 causes the signal output unit 21 to output a DMX signal in which data corresponding to the content of the lighting control of each luminaire L is arranged on the channel CH corresponding to each luminaire L. The control unit 24 can be configured by, for example, a one-chip microcomputer having a built-in memory.

The display unit 25 and the touch panel unit 26 can form a man-machine interface of the controller 2. The display unit 25 is driven by the display driver unit 27 to display various types of information and the like. The touch panel unit 26 detects a touch operation such as an operation button displayed on the display unit 25, and outputs a detection signal to the control unit 24.

Next, each luminaire L of the present embodiment has a lighting load 31, a signal receiving unit 32, a lighting circuit unit 33, a control unit 34, and a storage unit 35.

The illumination load 31 has, for example, a light source (not shown) in which a plurality of types of LEDs or organic EL elements having different emission colors are combined. The light source has a dimming function. The light source can individually adjust each emission intensity of RGBW by the dimming function. Therefore, the light source can adjust the emission intensity and the color temperature of the illumination light, respectively.

Further, the illumination load 31 may further have an optical unit (not shown) that optically processes the illumination light emitted by the light source. The optical unit may have, for example, an optical path adjusting function such as a focus adjusting mechanism and a tilt pan adjusting mechanism. The optical unit having an optical path adjusting function can, for example, adjust the focus and irradiation direction of the illumination light, that is, the angles of focus, tilt, and pan.

The signal receiving unit 32 receives the DMX signal output by the signal output unit 21 of the controller 2 from the DMX signal transmission line. The lighting circuit unit 33 includes a power supply unit that converts commercial power into power of a predetermined current used in the lighting circuit unit 33, and a power supply circuit unit that supplies the power converted by the power supply unit to the lighting load 31 (both shown in the figure). Do not have).

The control unit 34 can be configured by, for example, a general-purpose lighting control microcomputer. The control unit 34 acquires the data of the channel CH corresponding to its own luminaire L in the frame F of the DMX signal S received by the signal receiving unit 32. Further, the control unit 34 uses a part of the acquired data during the normal reception in which the signal receiving unit 32 normally receives the DMX signal S to supply the electric power supplied to the lighting load 31 by the lighting circuit unit 33. Control.

The storage unit 35 can be configured by, for example, a non-volatile semiconductor memory element such as a flash memory. The storage unit 35 stores the setting information of the channel CH in which the control unit 34 acquires the data corresponding to its own luminaire L in the frame F of the DMX signal S.

For example, in the storage unit 35 of the lighting fixture L of the fixture 1 shown in FIG. 5, the addresses 5 to 8 of the channel CH for transmitting the control data D1 shown in FIG. (Corresponding to continuous channels) is stored as setting information. The data of each channel CH of the control data D1 can be used for lighting control, for example, as an 8-bit pixel value for each color of RGBW of the light source in the lighting load 31 of the lighting fixture L of the fixture 1.

Further, in the storage unit 35 of the lighting fixture L of the fixture 2 shown in FIG. 5, the addresses 10 to 15 of the channel CH for transmitting the control data D2 shown in FIG. 4 (corresponding to a plurality of consecutive channels) are set information. Is remembered as. The data of each channel CH of the control data D2 is, for example, an 8-bit pixel value for each color of RGBW of the light source in the lighting load 31 of the lighting fixture L of the fixture 2 and a control value of the focus adjustment mechanism of the optical unit. It can be used for lighting control.

Further, addresses 20 to 30 (corresponding to a plurality of sets of continuous channels) of the channel CH for transmitting the control data D3 shown in FIG. 4 are set in the storage unit 35 of each lighting fixture L of the fixture 3 shown in FIG. It is stored as information. The data of each channel CH of the control data D3 is, for example, an 8-bit pixel value for each color of RGBW of the light source, a control value of the focus adjustment mechanism and the tilt pan adjustment mechanism of the optical unit in the lighting load 31 of the lighting fixture L of the fixture 3. Can be used for lighting control.

These setting information may be configured by, for example, a set of the first address of the consecutive addresses corresponding to the control data D1 to D3 and the address length indicating the number of consecutive channels from the first address. In particular, when the amount of control data D1 to D3 is large and a large number of channel channels are required to transmit the control data D1 to D3, the setting information should be configured by the pair of the head address and the address length. Therefore, it is possible to suppress an increase in the amount of setting information data.

When the setting information is configured by the pair of the head address and the address length, the setting information of the channel CH for transmitting the control data D1 is composed of the head address = 5 and the address length = 4. The setting information of the channel CH for transmitting the control data D2 and D3 is composed of the first addresses = 10 and 20 and the address lengths = 5 and 10, respectively.

The setting information can be input to the control unit 34 from a setting device (not shown) connected to the control unit 34 and stored in the storage unit 35, for example. The setting device may be, for example, a device using a mechanical switch such as a DIP switch, or an input device such as a touch panel having a display.

When the signal output unit 21 of the controller 2 and the signal reception unit 32 of the lighting fixture L have specifications corresponding to the RDM (Remote Device Management) communication protocol, the setting information is sent to the control unit 34 by remote control from the controller 2. It may be input and stored in the storage unit 35. In this case, the transmission line of the DMX signal may be used as the transmission line of the RDM communication of the bidirectional communication method, and the RDM signal may be transmitted from the controller 2 to the luminaire L.

The controller 2 intermittently and repeatedly transmits the DMX signal S to each luminaire L at each maximum refresh cycle. Therefore, the controller 2 changes the contents of the control data D1 to D3 of the DMX signal S with the passage of time, so that the control unit 34 of each luminaire L controls the illumination of the illumination load 31 via the lighting circuit unit 33. The state can be changed dynamically.

However, for example, if each luminaire L cannot normally receive the DMX signal S from the controller 2 due to a communication abnormality, even if the contents of the control data D1 to D3 are changed with the passage of time, the control of each luminaire L is performed. The unit 34 cannot acquire the control data D1 to D3. Then, the control unit 34 of each lighting fixture L performs control to set the lighting state at the time of an error determined in advance.

Since the control data D1 to D3 cannot be acquired as the lighting state at the time of an error, it is generally a static lighting state such as turning off, half lighting, or full lighting. Therefore, the luminaire L during the reception abnormality period in which the DMX signal S cannot be normally received cannot dynamically change the illuminating state. The break period B of the DMX signal S is not included in the reception abnormality period of the DMX signal S.

The communication abnormality of the DMX signal S may be caused by, for example, a poor connection of a DMX cable (not shown) that connects each luminaire L to the controller 2 in a daisy chain. Further, when the transmission path of the DMX signal S is wireless, there is a possibility that a communication abnormality of the DMX signal S may occur due to a reception failure of the wireless DMX signal S by the signal receiving unit 32 of each lighting fixture L. Further, noise is superimposed on the DMX signal S regardless of whether it is wired or wireless, which may cause a communication abnormality of the DMX signal S.

Therefore, in the lighting control system 1 of the present embodiment, the vacant channel CH of the frame F is used to continue the dynamic change of the lighting state of each luminaire L even during the reception abnormality period of the DMX signal S. The data is transmitted by the DMX signal S together with the control data D1 to D3. For example, in the DMX signal S shown in FIG. 4, the free channel CH is set after the address 31 of the frame F. Using this free channel CH, data used for lighting control of the luminaire L during the reception abnormality period of the DMX signal S is transmitted during the normal reception period of the DMX signal S and stored in the storage unit 35 of the luminaire L. Keep it.

In the example shown in FIG. 6, for the lighting fixture L of the fixture 1, the second 4-byte control data D1 and the second 4-byte control data D1 are used in each free channel CH at addresses 35 to 38 of the frame F. The control data D4 is transmitted. Further, each empty channel CH at addresses 509 and 510 near the end of the frame F controls each data D5 and D6 of time and pattern of 1 byte used when transitioning the lighting state of the lighting fixture L of the fixture 1. It is transmitted together with the data D1 to D4.

Of these, the second control data D4 transmitted on each free channel CH of addresses 35 to 38 is different from the lighting state corresponding to the first control data D1 transmitted on the channel CH of addresses 5 to 8. And. The data of each channel CH of the second control data D4 is, for example, lighting control as an 8-bit pixel value for each color of RGBW of the light source in the lighting load 31 of the lighting fixture L of the fixture 1 as in the control data D1. Can be used for.

The control data D1 is used to control the lighting state of each lighting fixture L during the normal reception period during which the lighting fixture L of the fixture 1 can normally receive the DMX signal. On the other hand, the control data D4 is used together with the control data D1 to control the lighting state of each lighting fixture L during the reception abnormality period in which the lighting fixture L of the fixture 1 cannot normally receive the DMX signal S. The two control data D1 and D4 are used for controlling the transition of the lighting state of each luminaire L between the state corresponding to the first control data D1 and the state corresponding to the second control data D4.

Further, the time data D5 transmitted on the free channel CH (corresponding to the time setting channel) at the address 509 is used to determine the required time t spent for the transition of the lighting state of the luminaire L. The time data D5 can be, for example, a value representing the required time t spent for the transition of the lighting state in 8 bits.

Further, the pattern data D6 transmitted on the empty channel CH (corresponding to the pattern setting channel) at the address 510 transitions the lighting state of the luminaire L between the state corresponding to the control data D1 and the state corresponding to the control data D4. It is used to determine the pattern to be made. In the present embodiment, a plurality of exponentiation curves (eg, Y = X ^ n) having different multipliers (n) are used as candidates for the transition pattern. Then, the individual address associated with the exponentiation curve of each candidate is used as the value of the pattern data D6.

When the power curve to be the transition pattern of the lighting state is specified by the pattern data D6, the control unit 34 specifies the transition pattern of the lighting state during the required time t from the graph shown in FIG. 8 of the specified power curve. be able to. The graph of FIG. 8 shows the case where the identified power curve is a 2.7 power curve.

The vertical axis of the graph of FIG. 8 shows the lighting state of the lighting fixture L after the transition from one of the states corresponding to the control data D1 and the state corresponding to the control data D4 to the other. This is the lighting level of the light source of the lighting load 31. The horizontal axis of the graph of FIG. 8 is the elapsed time from the start of transition of the lighting state of the luminaire L from one of the state corresponding to the control data D1 and the state corresponding to the control data D4 to the other.

The end point of the transition when the lighting level of the light source in the lighting state after the transition becomes 100% is the time of the refresh cycle of the DMX signal S, that is, the inverse of the refresh frequency of the DMX signal S, from the start time of the transition of the lighting state. It is the time when it has passed. For example, at the time when the elapsed time is t0 (0 ≦ t0 ≦ t), the lighting level of the light source in the lighting state after the transition is P (t0)% as shown in FIG. 8 (0 ≦ P (t0)). ≦ 100).

When the required time t of the time data D5 is shorter than the refresh cycle of the DMX signal S, the control unit 34 may adjust the lighting level of the light source according to the ratio of the required time t and the refresh cycle. .. Further, when the time data D5 is not defined in the DMX signal S, the control unit 34 may change the illumination state of the luminaire L with the characteristics according to the power curve specified by the pattern data D6. Further, when the pattern data D6 is not defined in the DMX signal S, the control unit 34 may change the illumination state of the luminaire L, for example, by the characteristic of a straight line of Y = X.

In the lighting control system 1 of the present embodiment, the controller 2 of FIG. 2 intermittently and repeatedly transmits the DMX signal S shown in FIG. 6 to each lighting fixture L at each maximum refresh cycle as in the case of the DMX signal S shown in FIG. do. When dynamically changing the lighting state of each luminaire L, the controller 2 of FIG. 2 changes the control data D1 to D3 of the DMX signal S shown in FIG. 6 with the passage of time.

The content of the control data D4 of the DMX signal S shown in FIG. 6 does not necessarily have to be changed with the passage of time as long as it is different from the content of the control data D1.

Further, in the lighting control system 1 of the present embodiment, among the lighting fixtures L of FIG. 2, the storage unit 35 of the lighting fixture L of the fixture 1 of FIG. 5 controls the second DMX signal S shown in FIG. The address of the channel CH for transmitting the data D4 is stored as setting information. This setting information, like the setting information of the control data D1 to D3, may be configured by, for example, a pair of the first address and the address length of the continuous addresses corresponding to the control data D4. When the setting information is configured by the pair of the head address and the address length, the setting information of the channel CH for transmitting the control data D4 is composed of the head address = 35 and the address length = 4.

Further, the storage unit 35 of the lighting fixture L of the fixture 1 of FIG. 5 also stores the information of the address of the channel CH for transmitting the time data D5 and the pattern data D6 of the DMX signal S shown in FIG. These address information are stored in the storage unit 35 as a channel CH in the frame F of the DMX signal S, in which the control unit 34 of the lighting fixture L of the fixture 1 acquires data corresponding to its own lighting fixture L.

The address information of the channel CH for transmitting the data D5 and D6 is also the same as the setting information of the control data D1 to D3, for example, depending on the combination of the first address and the address length of the addresses corresponding to the data D5 and D6, respectively. It may be configured. When the address information is configured by the pair of the head address and the address length, the address information of the channel CH for transmitting the time data D5 is composed of the head address = 509 and the address length = 1. The address information of the channel CH for transmitting the pattern data D6 is composed of the head address = 510 and the address length = 1, respectively.

The setting information or address information of the data D4 to D6 stored in the storage unit 35 is, for example, from a setting device (not shown) connected to the control unit 34 to the control unit 34, similarly to the setting information of the control data D1 to D3. It can be input and stored in the storage unit 35. If the signal output unit 21 of the controller 2 and the signal reception unit 32 of the lighting fixture L have specifications corresponding to the RDM communication protocol, the setting information or address of each data D4 to D6 can be remotely operated from the controller 2. Information may be input to the control unit 34.

Next, a lighting control method according to the present embodiment, which is performed in each lighting fixture L of the fixture 1 in which the controller 2 receives the DMX signal S of FIG. 6 intermittently and repeatedly transmitted in each refresh cycle, will be described. As shown in the flowchart of FIG. 7, the lighting control method of the present embodiment includes each step (steps S1 to S9) of reception, acquisition, storage, normal control, and transition control.

Of these, the reception step of step S1 is a step in which the signal receiving unit 32 receives the DMX signal S of FIG. 6 intermittently transmitted by the controller 2 at each lighting fixture L of the fixture 1.

In the acquisition step of step S3 of FIG. 7, during the normal reception period of the DMX signal S of FIG. 6, the control unit 34 receives data from the DMX signal S received by the signal receiving unit 32 in each lighting equipment L of the equipment 1. It is a step to acquire each. At this time, the control unit 34 acquires data from the address corresponding to the setting information and the address information stored in the storage unit 35 of the DMX signal S, respectively.

The storage step of step S5 in FIG. 7 is a step in which the control unit 34 stores the data acquired from the DMX signal S in FIG. 6 in the storage unit 35 in each lighting fixture L of the fixture 1.

Here, the control unit 34 distinguishes between the control data D1 acquired from each channel CH of the addresses 5 to 8 of the DMX signal S and the control data D4 acquired from each channel CH of the addresses 35 to 38. Each is stored in the storage unit 35. When the past control data D1 and D4 are stored in the storage unit 35, the control data D1 and D4 of the storage unit 35 are updated from the past one to the one acquired this time.

Further, the control unit 34 distinguishes the time data D5 and the pattern data D6 acquired from each channel CH of the addresses 509 and 510 of the DMX signal S from each other and also distinguishes them from the control data D1 and D4, and stores the storage unit 35. To memorize each.

In the normal control step of step S7 of FIG. 7, during the normal reception period of the DMX signal S of FIG. 6, in each lighting fixture L of the fixture 1, the control unit 34 stores the latest control data D1 stored in the storage unit 35. This is a step of controlling the lighting state of the lighting load 31 of the lighting fixture L. This normal control step is not executed in each lighting fixture L of the fixture 1 during the reception abnormality period during which the signal receiving unit 32 cannot normally receive the DMX signal S.

In the transition control step of step S9 of FIG. 7, during the reception abnormality period of the DMX signal S of FIG. 6, in each lighting fixture L of the fixture 1, the control unit 34 stores the latest control data D1 stored in the storage unit 35. , D4 is a step of controlling the lighting state of the lighting load 31 of the lighting fixture L.

Here, the control unit 34 determines and determines the required time t for the transition of the lighting state and the transition pattern of the lighting state according to the contents of the latest time data D5 and the pattern data D6 stored in the storage unit 35. The lighting state of the lighting fixture L of the fixture 1 is changed according to the contents. As a result, even if the DMX signal S of FIG. 6 cannot be normally received, the state in which the lighting state of the lighting fixture L of the fixture 1 changes dynamically can be continued. This normal control step is not executed in each lighting fixture L of the fixture 1 during the normal reception period during which the signal receiving unit 32 can normally receive the DMX signal S.

As is clear from the above description, in the lighting control system 1 of the present embodiment, by executing the process of step S1 of FIG. 7, the lighting control method according to the second aspect and the lighting according to the third aspect are executed. The receiving step in the control program is realized. That is, step S1 in FIG. 7 is a process corresponding to the receiving unit of the luminaire according to the first aspect.
