Unexamined-Japanese-Patent No. 2003-197381

  In the lighting control system as described above, the power supply of the host device including the control device (for example, the light control device) and the lighting controller (for example, the DMX controller, the signal converter, etc.) And are often provided independently. Here, if a power failure occurs on the higher-level device side while the power supply of the luminaire is continuing, it becomes a problem that useless extinguishing may occur in the luminaire at the time of the subsequent power recovery. This is because, in the host device, the light controller (for example, DMX controller) returns before the control device returns, that is, the light controller does not receive a command from the control device, and the light controller (for example, DMX signal) At the beginning of the output of). For example, in the DMX controller, the output DMX signal is set to be level 0 (light off command) when no command is input. Therefore, in a few seconds to a few minutes between the restoration of the lighting controller and the restoration of the control device, the lighting apparatus continues to be turned off even if it is powered.

  Therefore, the present invention realizes a configuration that avoids unnecessary turning off of the lighting device at the time of power recovery of the control device and the lighting controller in a lighting controller that outputs a lighting control signal to the lighting device according to an input from the control device. To be a task. Another object of the present invention is to provide a lighting control system using such a lighting controller.

  The lighting controller of the present disclosure includes an external input reading unit capable of reading the upper control signal input from the control device, and a lighting control signal including a control command based on the upper control signal when the upper control signal is read. A signal generation output unit configured to generate a light control signal including a turn-off command when the upper control signal is not read out, and to output the generated light control signal to the light fixture, and after activation of the light controller And a signal output limiting unit for limiting generation of a light control signal including a turn-off command or output to a lighting fixture during a limited period of time.

  According to the above-mentioned lighting controller, in a configuration in which the lighting control signal including the turn-off command can be generated by the signal generation / output unit when the upper control signal is not read from the external input reading unit, The signal output limiter limits the output of the lighting control signal including the turn-off command to the lighting apparatus. That is, the situation where the lighting fixture is turned off by the lighting control signal including the turn-off command during the start-up period after the lighting controller starts at the time of power recovery after the power failure and before the control device starts is suppressed. As a result, in the lighting controller that outputs the lighting control signal to the lighting device according to the input from the control device, it is possible to avoid useless turning off of the lighting device at the time of power recovery of the control device and the lighting controller.

  In an example of the first aspect, the signal output limiting unit is configured to stop generation or output of all the illumination control signals in the limitation period. This makes it possible to suppress the illumination control signal including the turn-off command with a simple control configuration.

  In another example of the first aspect, the signal output limiting unit is configured to stop generation or output of a lighting control signal including a turn-off command and to generate and output a lighting control signal including a control command in a limited period. Be done. As a result, during the limited period and after the control device recovers, lighting control based on the input upper control signal becomes possible, and early substantial or pseudo recovery of the lighting control in the lighting fixture is achieved. It becomes possible.

  In an example of the second aspect, the signal output limiting unit is configured to cause the signal generation output unit to generate and output a lighting control signal including a non-light-off command for full light or dimming lighting in a limited period. . Thereby, as long as the lighting controller is activated, it is possible to execute the lighting state or lighting pattern of the predetermined full light or dimming during the limited period regardless of the specification when the lighting control signal is not received in the lighting fixture This increases the versatility of the lighting controller.

  In another example of the second aspect, a storage medium reading unit capable of reading control data from a removable storage medium is provided, and the signal output limiting unit controls the read out from the storage medium reading unit during the limitation period. A lighting control signal including a non-turn-off command based on data is generated and output to the signal generation / output unit, and after a limited period has elapsed, a lighting control signal including a control command based on the upper control signal read from the external input reading unit The generation output unit is configured to generate and output. By this, as long as the lighting controller is activated, regardless of the specification when the lighting control signal is not received in the lighting fixture, the lighting condition or lighting pattern of the freely-settable total light or dimming can be executed during the limited period. And the flexibility of the lighting controller is increased.

  In another example of the second embodiment, a non-volatile memory is provided, and the signal generation / output unit sequentially stores the control instruction to be output in the non-volatile memory as a preliminary control instruction, and the signal output limiting unit operates during the limitation period. , Configured to cause the signal generation output unit to generate and output a lighting control signal including a preliminary control command. Thereby, as long as the lighting controller is activated, the lighting state or lighting pattern immediately before the power failure in the lighting controller and the control device is executed during the limited period regardless of the specification when the lighting control signal is not received in the lighting fixture And the versatility of the lighting controller is enhanced.

  In each example of the second aspect, in a limited period, a lighting control signal including a non-lighting command or a preliminary control command is output based on the light-off command, and a lighting control signal including a control command is output based on the control command It may be configured as follows. As a result, during the limited period and after the control device recovers, lighting control based on the input upper control signal becomes possible, and early substantial or pseudo recovery of the lighting control in the lighting fixture is achieved. It becomes possible.

  The lighting controller according to the first or second aspect may further include a time limit setting unit configured to set the length of the time limit according to a user input. As a result, the limited period length can be set according to the specification of the control device connected to the lighting controller, and the flexibility or versatility of the lighting controller is increased.

  The lighting controller of the third aspect includes an external input detection unit that ends the limited period in response to the detection of the input of the upper control signal from the control device. As a result, the start period of the light controller and the start of the control device substantially match the start period and the limit period, which may occur between the end of the start period and the end of the limit period if they do not match. Processing of the illumination control signal in the illumination controller is omitted, and the control configuration can be simplified.

  In addition, the external input detection unit may be configured to end the limited period when the input of the upper control signal from the control device is not detected by a predetermined time period after the transition to the limited period. Thereby, the continuation of the unnecessary lighting in a lighting fixture is avoided at the time of failure of a control device, etc.

FIG. 5 is a block diagram of a lighting control system including a DMX controller according to the first and second embodiments of the present invention. FIG. 7 is a block diagram of a lighting control system including a DMX controller according to a third embodiment of the present invention.

First Embodiment
FIG. 1 shows a block diagram of a lighting control system 1 according to a first embodiment. The lighting control system 1 includes a system host device 2, a distribution board 5, and lighting fixtures 6-1 to 6-n. The system host device 2 includes a DMX controller 3 (an example of a lighting controller) and a controller 4. The DMX controller 3 and the control device 4 are supplied with power from the power supply 20, and the lighting fixtures 6-1 to 6-n are supplied with power from the power supply 50 of the distribution board 5. Each of the power supplies 20 and 50 may be a commercial power supply, a stabilized power supply, or a breaker for shutting off / energizing such a power supply system, a main power supply, or the like. The lighting fixtures 6-1 to 6-n will be collectively referred to as the lighting fixture 6 generically or on behalf of any one. Moreover, although the specific configuration (the kind of light source etc.) may differ, respectively, the lighting fixture 6 shall have the same configuration on a block diagram. The DMX controller 3 and the control device 4 are connected by a LAN communication line, the DMX controller 3 and the lighting devices 6 are connected by an appropriate communication line, and the lighting devices 6-1 to 6-n are daisy chained. Alternatively, the DMX controller 3 and each lighting fixture 6 may be wirelessly connected.

  The DMX controller 3 includes a power supply circuit 30, a storage medium reading unit 31, an external input reading unit 32, a signal generation output unit 33, a signal output limiting unit 34, a timer 35, a time limit setting unit 36, and a memory 37. These units are connected to each other in such a manner that they can exchange current, voltage, signal or data. The DMX controller 3 also includes a storage medium interface (I / F) 31 a connected to the storage medium reading unit 31, an input I / F 32 a connected to the external input reading unit 32, and a transmission connected to the signal generation output unit 33. And an input I / F 36a connected to the time limit setting unit 36. The memory 37 includes a ROM, a RAM, and the like that store programs and data. The storage medium reading unit 31, the external input reading unit 32, the signal generation / output unit 33, the signal output limiting unit 34, the timer 35, and the time limit setting unit 36 can be included in a processing unit such as a CPU (not shown). This processing unit can also execute general CPU functions such as general processing of the above components in the DMX controller 3.

  The power supply circuit 30 receives power supply from the power supply 20 and supplies an operating voltage to each part in the DMX controller 3. As a result, the DMX controller 3 is activated within several seconds after the power supply 20 is turned on, and the components in the DMX controller 3 start operating.

  The storage medium reading unit 31 reads data from a storage medium (not shown) inserted in the storage medium I / F 31a. For example, the storage medium is an SD card, the storage medium I / F 31a is an SD card slot, and the data read out is control data for illumination control. The storage medium may be another removable storage medium such as a USB memory, and the storage medium I / F 31a may be a port corresponding to the storage medium. The control data read from the storage medium reading unit 31 may be stored in the memory 37.

  The external input reading unit 32 reads the upper control signal input from the control device 4 via the input I / F 32a. The input I / F 32a is a LAN port in the present embodiment. When the DMX controller 3 is used alone without being connected to the control device 4, the DMX controller 3 operates solely based on control data read from the storage medium by the storage medium reading unit 31. On the other hand, when the DMX controller 3 is used by being connected to the control device 4 as in the present embodiment, the control device 4 read by the external input reading unit 32 normally without using the storage medium. Operate based on the upper control signal from In the present disclosure, the upper control signal or control data defines the identification of the lighting device 6 to be controlled, the illumination state (schedule) with respect to the elapsed time in the illumination control, and the like.

  The signal generation / output unit 33 generates a lighting control signal based on either the control data read by the storage medium reading unit 31 or the upper control signal read by the external input reading unit 32. In the present embodiment, the lighting control signal is a DMX signal based on the DMX 512 standard or the like, and in that frame, the address of the lighting device 6 to be controlled (in the range up to 512 channels per universe), control instruction, etc. . The control command is formed of, for example, 8-bit data, and is represented by a light control command value (level 0 (off) to level 255 (full light)).

  Here, when neither control data nor an upper control signal is obtained, the signal generation / output unit 33 generates a DMX signal including data bits of level 0 (turn-off command) for all channels (addresses). Further, the signal generation / output unit 33 outputs the generated DMX signal from the transmission unit 33 a to each of the lighting devices 6. That is, the signal generation / output unit 33 normally outputs a DMX signal indicating a control command (level 0 to 255) based on the upper control signal or control data (upper control signal in the present embodiment) to the lighting apparatus 6 to perform upper control When the signal or control data is not read out, the DMX signal indicating the turn-off command (level 0) is output to the lighting apparatus 6. The transmitter 33a may be a transmitter capable of DMX communication, and transmits the DMX signal in an appropriate format (Manchester code).

  By the way, if the power supply 20 fails in power supply continuation of the power supply 50, the system host device 2 (DMX controller 3) will not output the DMX signal. In the luminaire 6, when the reception of the DMX signal is interrupted, the luminaire 6 is configured to maintain the previous lighting state or perform all-light or dimming lighting. Here, when the power supply 20 recovers from power, the DMX controller 3 is activated immediately (after several seconds), and then the control device 4 is activated. In the present disclosure, a period before activation of the control device 4 after activation of the DMX controller 3 is referred to as “activation period”. Although the start-up period strictly corresponds to the start-up required time of the control device 4 minus the start-up required time of the DMX controller 3, the start-up required time of the DMX controller 3 is several seconds. Correspond to the required time. As described above, in the startup period before startup of the control device 4 after startup of the DMX controller 3, the upper control signal is not input to the DMX controller 3. Here, assuming that the signal output limiting unit 34 is not present, the signal generation / output unit 33 generates the DMX signal of the turn-off command (level 0) as described above in the start-up period after power recovery of the power supply 20. It will output to the lighting fixture 6. Therefore, in the starting period, unintended turn-off is performed and continued in all the lighting devices 6.

  Therefore, the signal output limiting unit 34 limits the output of the DMX signal including the turn-off command over a predetermined period after the restart of the DMX controller 3. The output limitation of the DMX signal may be performed by limiting the generation of the DMX signal by the signal generation / output unit 33, or the output from the transmission unit 33a of the DMX signal by the signal generation / output unit 33 to the lighting apparatus 6 It may be implemented by restriction.

  In the present disclosure, the predetermined period after activation of the DMX controller 3 is referred to as a limited period. The limit period length (limit time) is set to be longer than the above-described start period. The startup required time of the control device 4 is specified from the specification or measured value of the control device 4 and is several seconds to 5 minutes at maximum. Therefore, the above time limit is set to, for example, 10 seconds to 5 minutes, preferably 1 to 5 minutes, as appropriate. The signal output limiting unit 34 uses the timer 35 to count the time limit.

(A) An example of output limitation (complete stop of signal output)
In the limitation period, the signal output limiting unit 34 may be configured to stop the generation of all DMX signals by the signal generation / output unit 33, or all DMX via the transmission unit 33a by the signal generation / output unit 33. It may be configured to shut off the output of the signal. In the latter case, the signal output limiting unit 34 may stop the output operation of the signal generation / output unit 33, or stop the operation (transmission) of the transmission unit 33a while the signal generation / output unit 33 is operated. It is also good.

  In the above-described example, the upper control signal may be acquired by the external input reading unit 32 after the start of the limited period, ie, while the output of the DMX signal is restricted by the signal output restriction unit 34. It can occur. In this case, the signal generation / output unit 33 stores the upper control signal in the memory 37 as internal processing, and outputs the upper control signal stored in the memory 37 to the lighting fixture 6 after the limited period ends. Good. Alternatively, the signal generation and output unit 33 may discard the upper control signal and output the upper control signal acquired from the external input read unit 32 at that time after the end of the limited period.

(B) Another example of output limitation (filtering of signal output)
In the limitation period, the signal output limiting unit 34 stops the output of the DMX signal including the turn-off command among the DMX signals generated by the signal generation output unit 33 and executes the filtering to output the other DMX signals. Good. That is, the signal output limiting unit 34 may filter out a frame having data bits of level 0 “00000000” in the frame of the DMX signal within the limited period. As described above, by filtering the DMX signal including the turn-off command, the output of the DMX signal (the DMX signal other than the level 0) based on the upper control signal is in the period after the start period elapses even during the limited period. It becomes possible. However, if level 0 is included in the upper control signal, the DMX signal is interrupted by the DMX signal in the level 0 period due to the above-mentioned filtering, and in the lighting device 6, the lighting state immediately before or predetermined (all light etc.) It should be noted that the lighting state of is implemented.

  The time limit setting unit 36 is configured to set a time limit (time limit) according to a user input. The user input may be read from the storage medium I / F 31 a by the storage medium reading unit 31 or may be read according to a user operation from the separate input I / F 36 a or the like. The input I / F 36a may be an interface such as a plurality of buttons and a display (liquid crystal screen) provided on a housing (not shown) of the DMX controller 3, a dip switch, a rotary switch, and the like. Here, on the display, options regarding setting or operation, input values or setting values, etc. may be switched and displayed on the screen of a plurality of layers. The plurality of buttons may be, for example, movement of an active area or a cursor, arrow keys for inputting numerical values, selection of options, predetermined number of number keys for inputting numerical values, and selection, determination, deletion, etc. It suffices to include function keys for predetermined processing. Thereby, the time limit can be set according to the control device 4 connected to the DMX controller 3, and the flexibility or versatility of the DMX controller 3, the system higher-level device 2 or the lighting control system 1 is increased.

  The control device 4 is, for example, an ITACS manufactured by Iwasaki Electric Co., Ltd., and includes a power supply circuit 40, a processing unit 41, a storage unit 42, and a user I / F 43. The processing unit 41 is connected to an output I / F 41 a such as a LAN port. The processing unit 41 is a processor or the like that integrally controls the entire control device 4. The storage unit 42 stores programs and data, and in particular, stores data for generating a higher control signal input from the user I / F 43. The user I / F 43 is, for example, a graphical user interface (GUI) on a touch panel.

  The power supply circuit 40 receives power supply from the power supply 20 and supplies an operating voltage to each part in the control device 4. As a result, the processing unit 41 and the like start up after a maximum of five minutes. When activated, the processing unit 41 reads the designated upper control signal from the storage unit 42, and outputs it to the DMX controller 3 from the output I / F 41a. That is, the processing unit 41 outputs the upper control signal to the DMX controller 3 after the startup period has elapsed since the power recovery of the power supply 20.

  Each lighting fixture 6 includes a transmission / reception circuit 60, a lighting circuit 61, and a light source 62. The transmission / reception circuits 60 of the lighting fixtures 6-1 to 6-n are connected in a daisy chain. The light source 62 is a dimmable light source such as, for example, an LED.

  The transmitting / receiving circuit 60 receives the DMX signal from the DMX controller 3 (or the lighting fixture 6 if there is the lighting fixture 6 in the previous stage), takes in the frame of its own address, Transfer to) if there is one. In addition, the transmission / reception circuit 60 converts the control command or the turn-off command indicated by the captured frame into a predetermined voltage signal (for example, a PWM signal or the like), and outputs the signal to the lighting circuit 61. That is, when the control command is included in the DMX signal, the transmission / reception circuit 60 generates a control signal for lighting, dimming or extinguishing the light source 62 according to the control command. Further, when the DMX signal includes a turn-off command, the transmission / reception circuit 60 generates a turn-off signal for turning off the light source 62 according to the turn-off command. In addition, when there is no frame to be taken in, the transmission / reception circuit 60 generates a control signal so as to maintain the current (previous) lighting state, or to execute a predetermined lighting state (all light or light control lighting). Generate control signals of Alternatively, the transmission / reception circuit 60 detects that the DMX signal is not received prior to the determination of the presence or absence of the frame to be taken in, and executes the control signal for maintaining the current state (immediately before) the lighting state or all light or dimming lighting. Control signals may be generated.

  The lighting circuit 61 generates a current (a current waveform, a current whose current value is controlled, etc. is controlled) suitable for lighting the light source 62 from the voltage supplied from the power supply 50, and supplies the current to the light source 62. For example, when the power supply 50 is an AC power supply and the light source 62 is an LED, the lighting circuit 61 generates a DC constant current from the rectification circuit that performs full-wave rectification of the AC power supply and the rectification circuit Is provided to the light source 62. Thus, the lighting circuit 61 supplies power to the light source 62 in accordance with the control signal generated by the transmission / reception circuit 60, and lighting control of the light source 62 is executed.

  As described above, the DMX controller 3 according to the present invention is based on the external input reading unit 32 capable of reading the upper control signal input from the control device 4 and the upper control signal when the upper control signal is read. A signal generation output unit 33 configured to generate a DMX signal including a control command, and generate a DMX signal including a turn-off command when the upper control signal is not read out, and to output the generated DMX signal to the lighting apparatus 6 And a signal output limiter 34 for limiting the generation of a DMX signal including an extinguishing command or the output to the luminaire 6 in a limited period after activation of the lighting controller 3.

  As described above, in the configuration in which the DMX signal including the turn-off command can be generated by the signal generation / output unit 33 when the upper control signal is not read from the external input read unit 32, the DMX including the turn-off instruction during the limited period. The output of the signal to the luminaire 6 is limited by the signal output limiter 34. That is, at the time of power recovery, the situation where the lighting fixture 6 is turned off by the lighting control signal including the turn-off command is suppressed during the start-up period after the DMX controller 3 starts and before the control device 4 starts. . Thus, in the DMX controller 3 that outputs the DMX signal to the lighting apparatus 6 according to the input from the control apparatus 4, uselessness in the lighting apparatus 6 at the time of power recovery of the control apparatus 4 and the DMX controller 3 (system host device 2) It is possible to avoid the problem of light off.

  In particular, in the example of the DMX controller 3 according to the present embodiment, the signal output limiting unit 34 is configured to stop generation or output of all DMX signals in the limitation period. As a result, the above-described effect can be obtained with a simple control configuration.

  Further, in another example of the DMX controller 3 according to the present embodiment, the signal output limiting unit 34 stops the generation or output of the illumination control signal including the turn-off instruction in the limitation period, and generates the illumination control signal including the control instruction. And configured to output. As a result, lighting control based on the upper control signal input can be performed during the limited period and after the start-up period, and early or substantial recovery of lighting control in the lighting fixture 6 is possible. Become.

Second Embodiment
In the first embodiment, the configuration has been described in which the output restriction of the DMX signal in the restriction period is performed by the output stop of the DMX signal including the turn-off instruction. On the other hand, in the present embodiment, a configuration is shown in which the output restriction of the DMX signal in the restriction period is performed by conversion from the turn-off instruction to another instruction.

  The block diagram of the illumination control system 1 according to the present embodiment is the same as the block diagram of the first embodiment shown in FIG. In the present embodiment, the function and operation of the signal output limiter 34 are different from those of the first embodiment.

(C) An example of output limitation (output of a predetermined non-lighting off instruction)
In the limited period, the signal output limiting unit 34 generates a DMX signal including a predetermined dimming control (for example, 25%, 50%, 75%, etc.) or a non-lighting off instruction for full light lighting from the signal generation output unit 33 It can be made to output. It is assumed that the contents of the predetermined non-light-off instruction are stored in advance in the memory 37. In the limited period, all the DMX signals generated and output by the signal generation / output unit 33 may be configured to be the DMX signal of the non-turn-off instruction, or only the DMX signal including the turn-off instruction is the non-turn-off instruction May be configured to be converted to a DMX signal of In the latter case, the DMX signal including the control command may be output during the limited period and after the start-up period. In any case, all the lighting fixtures 6 will perform dimming or full light lighting during the limited period.

(D) Another example of output restriction (output of settable non-lighting off instruction)
It is also possible to use a removable storage medium (such as an SD card) inserted into the storage medium I / F 31a during the limited period to output a DMX signal including a non-light-off command. That is, control data read by the storage medium reading unit 31 is employed only during the limited period. In the control data, a non-lighting-off instruction is specified which specifies a mode of predetermined dimming or lighting in a limited period. However, in the signal generation / output unit 33 or the signal output restriction unit 34, the upper control signal needs to be prioritized over the control data in the normal operation. In the limited period, all the DMX signals generated and output by the signal generation / output unit 33 may be configured to be the DMX signal of the non-turn-off instruction, or only the DMX signal including the turn-off instruction is the non-turn-off instruction May be configured to be converted to a DMX signal of In the latter case, the DMX signal including the control command may be output during the limited period and after the start-up period. Also in this example, all the lighting fixtures 6 perform the dimming control or the total light control in the limited period.

  In addition, the non-lighting off command in (C) and (D) may not necessarily prescribe the fixed lighting state, and the lighting state which changes with time, the lighting state which is different for every lighting fixture 6, or A combination (these are collectively called "lighting pattern") may be prescribed. The lighting pattern may be a lighting mode pattern for preventing the user of the lighting apparatus 6 from giving a visual discomfort, or a lighting mode pattern for alerting the user of the lighting apparatus 6 It is also good. In the latter case, it is possible to make the user of the lighting apparatus 6 recognize that a power failure and a power recovery have occurred in the system higher-level device 2 or that the system higher-level device 2 is in the start-up period.

(E) Another example of output restriction (output of control instruction immediately before power failure)
A configuration is also possible in which the non-volatile memory portion of the memory 37 is used during the limited period to reproduce the DMX signal immediately before the power failure. In this case, during the normal operation, the signal generation / output unit 33 sequentially stores the control instruction to be output in the memory 37 as a preliminary control instruction. Then, in the limited period after power recovery, the signal output limiting unit 34 generates the DMX signal including the latest spare control instruction stored in the memory 37 or the spare control instruction for the latest predetermined period to the signal generation output unit 33. And output. In the limited period, all the DMX signals generated and output by the signal generation / output unit 33 may be configured as the DMX signal of the preliminary control instruction, or only the DMX signal including the turn-off instruction may be the preliminary control instruction. May be configured to be converted to a DMX signal of In the latter case, a DMX signal including a control command may be output in a limited period. Thus, in the limited period, each of the lighting devices 6 performs the lighting state immediately before the power failure or the lighting pattern of the predetermined period immediately before the power failure.

  As described above, also in the present embodiment, as in the first embodiment, since the signal output limiter 34 limits the output of the DMX signal including the turn-off command to the lighting fixture 6 during the limitation period, the startup period The situation where the lighting apparatus 6 is turned off is suppressed by the DMX signal including the turn-off command. Therefore, in the DMX controller 3 which outputs the DMX signal to the luminaire 6 in accordance with the input from the control device 4, uselessness in the luminaire 6 at the time of power recovery of the controller 4 and the DMX controller 3 (system host device 2) It becomes possible to avoid turning off.

  In particular, in an example of the DMX controller 3 of the present embodiment, the signal output limiting unit 34 generates a DMX signal including a non-lighting off instruction for all light or dimming lighting in the signal generation output unit 33 in the limited period. It is configured to output. Therefore, as long as the DMX controller 3 is activated, it is possible to execute the lighting condition or lighting pattern of the predetermined full light or dimming during the limited period regardless of the specification when the DMX signal is not received in the lighting device 6 Thus, the versatility of the DMX controller 3 and the system higher-level device 2 is enhanced.

  Alternatively, in another example of the DMX controller 3 according to the present embodiment, the signal output limiting unit 34 generates a DMX signal including a non-lighting-out instruction based on control data read from the storage medium reading unit 31 in a limited period. Configured to cause the signal generation / output unit 33 to generate and output a DMX signal including a control instruction based on the upper control signal read from the external input reading unit 32 after the limited period has elapsed.

Third Embodiment
In the first and second embodiments described above, the time limit is substantially fixed regardless of the time required for starting the control device 4. However, in the present embodiment, the time limit for the time required for starting the control device 4 is The configuration is shown to be variable accordingly.

  FIG. 2 shows a block diagram of the illumination control system 1 according to the present embodiment. In the present embodiment, the same components as those in the first or second embodiment are denoted by the same reference numerals, and the description thereof will be omitted. In the present embodiment, an external input detection unit 38 is provided instead of the time limit setting unit 36 and the timer 35 of the first or second embodiment.

  The external input detection unit 38 detects the presence or absence of the input of the upper control signal from the control device 4 in the external input reading unit 32 after the DMX controller 3 is activated. When the input of the upper control signal from the control device 4 is not detected, the external input detection unit 38 performs the output restriction of the DMX signal by the signal output restriction unit 34. On the other hand, when the control device 4 is activated and the external input detection unit 38 detects the input of the upper control signal from the control device 4, the output restriction of the DMX signal by the signal output restriction unit 34 is released. Therefore, the limitation period ends substantially immediately after the activation of the control device 4.

  The output limitation of the DMX signal in the present embodiment is the complete stop of the signal output described above in the first and second embodiments, the filtering of the signal output of (B), and the output of a predetermined non-light-off command. (D) The output of the non-lighting instruction which can be set, or (E) the output limitation by the output of the control instruction immediately before the power failure.

  In addition, the external input detection unit 38 ends the limited period when the input of the upper control signal from the control device 4 is not detected (that is, when it times out) by the time when the predetermined time elapses after shifting to the limited period. It may be configured as follows. Thereby, continuation of unnecessary lighting in lighting fixture 6 is avoided at the time of failure of control device 4 or the like.

  As described above, the DMX controller 3 of the present embodiment includes the external input detection unit 38 that ends the limited period in response to detection of the input of the upper control signal from the control device 4. As a result, the start-up period and the limit period substantially match. That is, internal processing of the DMX signal that can occur between the end of the start period and the end of the limit period when the start period and the limit period do not match is omitted. Therefore, the same effect as that of the first or second embodiment can be obtained, and the control configuration of the DMX controller 3 can be simplified.
