Abstract

<P>PROBLEM TO BE SOLVED: To provide a luminescent device capable of representing a variety of emission patterns in a simple device configuration and facilitating installation work. <P>SOLUTION: This luminescent device stores the same blinking control pattern data in a number of light-emitting units connected in series, so that each light-emitting unit can read out the blinking control pattern data for emission blinking. On receiving a synchronizing signal from the last connected light-emitting unit, each light-emitting unit changes the read-out position of light-emitting control pattern data according to an offset value set in the light-emitting unit for emission blinking. The synchronizing signal is superimposed on a blink activation signal to be output from the controller of each light-emitting unit to an emitter, so that the emitter can be used as a transmission path for emission propagation to the next light-emitting unit. The synchronizing signal is also superimposed on the blink activation signal through frequency modulation at a cycle timing with a pulse representing that emission is ON in a duration of the blink activation signal. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a light emitting device that performs illumination light emission by attaching a plurality of light emitters such as LEDs to a wall surface of a building and blinking each light emitter at a predetermined light emission timing.

  By controlling the light emission of multiple light emitters attached in a line for each light emitter, the entire light emission line blinks all at once, gradation light emission that gradually changes the color while mixing intermediate colors, or along the light emission line A light-emitting device that displays light in a fluidized manner is known.

  The present applicant has already proposed a light-emitting display system including a light-emitting device and a light-emitting data editing device as shown in Prior Art 1, but this type of light-emitting device can be roughly divided into two types. One is a high-functional type in which a light emission blinking pattern can be created by an editing device as in Patent Document 1 below, and the light emission blinking pattern stored on the light emitting device side can be freely rewritten. This type is characterized by the fact that the light emission display can be performed with the original light emission blinking pattern desired by the light emitting device owner or administrator, but at the same time it is necessary to learn the operation method of the editing device, or the whole From the standpoint of demanding simplicity and ease, the equipment configuration is complicated, such as the need for a controller to control, and it has the disadvantages of being overly functional and difficult to use. On the other hand, the other type is a device of a type that does not have a function of creating a light emission / flashing pattern and is selected from light emission patterns prepared in advance. This type has a feature that the device configuration is simple and the light emission display can be performed simply by energizing and selecting the light emission blinking pattern, so that it is easy to handle and can be used easily.

The latter of the above two types can be viewed as having only the minimum necessary functions as compared with the high-function type at the price of giving priority to easy handling. One of the narrowed functions is to select the light emission blink pattern from the pre-prepared patterns, but because there are multiple light emitting operation types that match to some extent at any installation location. , Can be fully utilized in the prepared types.

  By the way, in the conventional apparatus, when the blinking control of the plurality of light emitting units constituting the light emitting line is performed based on the light emission blinking pattern, the following method is used. The first method is to store a flashing pattern with different movements for each light-emitting unit constituting the light-emitting line and start the flashing operation at the same time for all the light-emitting units. The light emission blinking pattern is expressed. In the second method, the light emission blinking patterns to be stored in the plurality of light emitting units constituting the light emitting line are set to the same contents, but independent absolute addresses are assigned to the plurality of light emitting units, and the respective light emitting units are arranged. The unit expresses one light emission blinking pattern as a whole by changing the reading start position of the light emission blinking pattern according to the address given to itself.

  Certainly, according to these methods, it is possible to express one light emission blinking pattern for the entire light emitting line without requiring a controller for collectively controlling the plurality of light emitting units constituting the light emitting line. However, the above two methods have the following problems. In the first method, it is necessary to prepare and store a light emission blinking pattern for each light emitting unit, so that each light emitting unit is different and is difficult to handle and manage during production and installation work. is there. In the second method, although the light emission blinking pattern stored in each light emitting unit is common, it is necessary to assign an individual absolute address to each light emitting unit. Even when address setting is performed with a dip switch or the like according to the mounting state, handling management is also difficult.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a light-emitting device that can solve various problems as described above and can display various light emission while having a simple device configuration and can be easily installed.

  In order to achieve the above object, the present invention provides (1) a light emitting unit in which light emitters are arranged so as to emit multicolor light, a controller for controlling the light emitting unit based on flashing control pattern data stored in advance, and the controller And a signal line extending from the light emitting part to the outside after connecting the light emitting part, and a plurality of light emitting units connected in series via the signal line to flash the light emitter In the light emitting device that performs illumination light emission, the controller of the light emitting unit includes a blinking drive unit that blinks and drives the light emitting body of the self light emitting unit, and the blinking of the other light emitting unit from the self light emitting unit to another light emitting unit. Synchronization signal output means for outputting a synchronization signal for defining operation start timing, and the synchronization signal input from the other light emitting unit to the self light emitting unit A synchronizing signal receiving means for receiving, and a blinking for outputting a reading position designation signal so as to start a blinking driving operation in the blinking driving means from a predetermined position of the blinking control pattern when the synchronizing signal is received by the synchronizing signal receiving means An operation synchronizing means; and a signal superimposing means for superimposing a synchronizing signal output from the synchronizing signal output means on a blinking driving signal output from the blinking driving means toward the light emitter of the light emitting unit. Based on the blinking drive signal included in the output signal from the flashlight, the luminous body of the self-light-emitting unit is driven to blink, and the synchronization signal superimposed on the blinking drive signal is transmitted to other light-emitting units connected in series to the self-light-emitting unit. A featured light emitting device is proposed.

(2) A light emitting unit in which light emitters are arranged so as to emit multicolor light, a controller for controlling the light emitting unit based on flashing control pattern data stored in advance, and light emission after connecting the controller and the light emitting unit. A light-emitting device that includes a plurality of light-emitting units each including a signal line extending from a portion to the outside, and a plurality of the light-emitting units are connected in series via the signal line and blinks a light-emitting body. The light emitting unit controller includes:
Flashing drive means for driving the light emitter of the self-light-emitting unit to flash, communication signal output means for outputting communication signals regarding various settings of the light-emitting unit from the self-light-emitting unit to other light-emitting units, and the self-light-emitting unit from the other light-emitting units A communication signal receiving means for receiving the communication signal input to the receiver, and receiving when the communication signal is received by the communication signal receiving means to set a set value included in the communication signal as a seed set value of the self-light-emitting unit A signal setting unit; and a signal superimposing unit that superimposes a communication signal output from the communication signal output unit on a flashing driving signal output from the flashing driving unit toward the light emitter of the light emitting unit. Based on the blinking drive signal included in the output signal from the flashlight, the light emitting body of the self-luminous unit is driven to blink, and the communication signal superimposed on the blinking drive signal is spontaneously emitted. Suggest emitting apparatus characterized by transmitting to the other light emitting units connected in series to the unit.

  In the proposed light-emitting devices (1) and (2), the signal superimposing process in the signal superimposing unit is a process of frequency-modulating the synchronization signal or the communication signal using the blinking driving signal output from the blinking driving unit as a carrier wave. desirable.

  Further, the signal superimposing means desirably superimposes the synchronization signal or the communication signal at the timing of the cycle in which the light emission on signal of the light emitter is present in the blinking drive signal.

  Further, the signal superimposing means provides a light emission off period for a short period and changes the on / off duty ratio to less than 100% when the cycle having the light emission on signal is 100%, and frequency-modulates the synchronization signal or communication signal. It is desirable to do.

  The light emitting unit includes at least two kinds of light emitters having different light emission colors, and a signal line for each light emission color of the light emitter, and the synchronization signal receiving means is a signal connected to each light emission color of the light emitter. It is desirable to perform an OR operation on the input signal from the line and receive a synchronization signal or a communication signal included in the operation result.

  According to the present invention, a plurality of light-emitting units constituting a light-emitting device can be made common without distinction, and individual management is not required in production and installation work, and handling is facilitated. In addition, a synchronization signal is used to align the light emitting operations of a plurality of light emitting units constituting the light emitting device and to provide regularity, and the synchronization signal is extended to the light emitting unit extending from the controller of each light emitting unit as a transmission path. Therefore, it is not necessary to lay a dedicated signal line for sending a synchronization signal, and the installation work can be facilitated while contributing to cost reduction. In addition, the light-emitting unit extending from the controller of each light-emitting unit is connected to the controller of another light-emitting unit, and the flashing drive signal output from the controller to the light-emitting unit is frequency-modulated with synchronization signals and communication signals related to various unit settings. Since transmission is performed, it is not necessary to provide a dedicated transmission path for transmitting a synchronization signal or a communication signal in the light emitting unit, and the product cost can be reduced.

  In addition, the timing of superimposing the synchronization signal and communication signal by frequency modulation on the blinking drive signal is the timing of the period in which the pulse indicating light emission is present in the blinking drive signal, so the duty ratio does not have the light emission on pulse. Frequency modulation is not performed at a period of zero%, and display noise caused by modulation processing itself that is not originally related to display can be prevented. Specifically, when no modulation is applied, a very short pulse is generated in order to distinguish the cycle by applying frequency modulation when the light is completely extinguished over one cycle, and the display flickers due to this pulse. Can be prevented from being visually recognized.

  When the synchronization signal or the communication signal is frequency-modulated to the blinking drive signal, when the on / off duty ratio is 100% occupied by the light emission on pulse over one period, the light emission is turned off for a predetermined time. Therefore, it is possible to prevent display noise caused by the modulation process itself that is not related to display. Specifically, when the pulse is in a high state for one period when no modulation is applied, even if a very short pulse falling occurs in order to distinguish the period by applying frequency modulation, Since the frequency modulation is performed in a state in which the light emission is turned off for a predetermined time, the short-time pulse falling associated with the modulation becomes inconspicuous, and a phenomenon in which the display flickers momentarily can be prevented.

In the sync signal receiving means / communication signal receiving means in which a separate signal line is provided for each color of the light emitter arranged in the light emitting section and the signal line extended from the light emitting unit in the previous stage is connected, the color of the light emission color An OR operation is performed on input signals from a plurality of signal lines corresponding to the number, and a synchronization signal and a communication signal are received. Therefore, it is not necessary to check the presence / absence of a synchronization signal / communication signal for all connected signal lines, and it is only necessary to check the result of OR operation, thereby reducing the load on signal processing. . Further, from the side of outputting the synchronization signal / communication signal, signal output is possible if any one of a plurality of light emission colors includes a light emission on-pulse, so that the signal transmission opportunities can be increased.
Preferred embodiments of the present invention will be described below with reference to the drawings.

Example 1
FIG. 1 is an explanatory diagram showing the overall configuration of a light emitting device according to a first embodiment of the present invention. Reference numeral 1 denotes a light emitting unit, and this light emitting unit includes a light emitting unit 2 and a controller 4. Further, the light emitting unit 2 is constituted by 16 lights 3 connected in series by a signal line 5. The light 3 is provided with R (red), G (green), and B (blue) LEDs as shown in the partially enlarged view in FIG. 1, and each color LED emits gradation light with 256 levels of brightness per color. In total, 16 million colors can be emitted. The 16 lights 3 connected in series are connected to the controller 4, and light emission is controlled based on 16 types of blinking control pattern data stored in advance in the controller. The 16 types of blinking control patterns include “a pattern that continues to emit light in a specific color”, “a pattern that displays multiple colors while gradually changing colors”, and “a plurality of colors that are switched instantaneously. There are multiple patterns, such as "Pattern", "Pattern that changes colors all at once while blinking 16 lights", and "Pattern that changes the brightness of the entire 16 lights with 1 / f fluctuation". A desired blinking control pattern can be selected by switching the selected rotary switch. The 16 lights connected to one controller are not individually controlled to emit light with different emission colors as being independent of each other, but the entire 16 lights constituting the light emitting unit 2 are one. The light emission is controlled as the same. Then, one light emitting unit 1 is configured as a whole, and is connected to a commercial power source via the AC adapter 6.

  The light emitting unit 1 configured in this way can be connected to different light emitting units 1. 16 signal lines 5 extending from the last light 3 connected in series are connected to the controller 4 'of another light emitting unit 1', and the same flashing control pattern is selected by the controller of the connected light emitting unit. Thus, it is possible to make 16 lights + 16 lights in total, that is, 32 lights in total are emitted in synchronization. When another light emitting unit 1 ″ is connected, it may be connected in the same manner. The flashing control patterns having the same contents are stored in the controllers of the light emitting units 1, 1 ′, 1 ″,. The same blinking control pattern can be set for each controller when a plurality of light emitting units are connected.

  Next, the controller 4 will be described in detail with reference to FIG. The controller 4 includes a pattern changeover switch 4-1, a luminance changeover switch 4-2, a speed changeover switch 4-3, a start switch 4-4, a selection button 4-5, and an enter button 4-6. The pattern changeover switch 4-1 is a switch for selecting a desired pattern from 16 types of flashing control patterns stored in advance in the controller, and one pattern can be designated by a 16-contact rotary switch. it can. The luminance changeover switch 4-2 is a switch for changing the luminance of the LED at the time of light emission display, and can be selected from 16 levels of brightness by a 16-contact rotary switch. The speed changeover switch 4-3 is a switch for changing the speed of the light emission operation performed based on the blinking control pattern. The speed changeover switch 4-3 can be selected from 16 stages of speed by a 16-contact rotary switch. The start switch 4-4 is a switch for switching the synchronization state of the light emitting operation for each light emitting unit when a plurality of light emitting units are connected as shown in FIG. 1, and other switches connected to each other by a 16-contact rotary switch. The synchronization state with the light emitting unit can be specified in 15 steps. The synchronized state in this case refers to a deviation in light emission operation when operating a plurality of light emitting units connected in series. When multiple light-emitting units are connected, the same flashing control pattern for each light-emitting unit is used as described above, but the light-emitting operation based on the flashing control pattern is the same for all light-emitting units. It is specified whether it is performed at the timing or delayed (advanced) from the adjacent light emitting unit. The 16-contact rotary switch is assigned steps +1 to +7 in the clockwise direction and -1 to -7 steps in the counterclockwise direction. By switching in the range of +1 to +7, a positive offset can be given, and the light emission operation can proceed in seven stages. Conversely, by switching in the range of −1 to −7, a negative offset can be given, and the light emission operation can be delayed in seven stages. Incidentally, the position corresponding to 0 o'clock of the rotary switch is assigned a state in which the timings coincide with each other without any advance or delay. Details regarding these operations will be described later.

  The selection button 4-5 is a button used when changing the emission color initially set to the specific blinking control pattern selected by the pattern changeover switch 4-1 to a desired color. For example, when specifying a light emission color such as “a pattern that continues to emit light in a fixed color”, the user can enter the color specification mode by pressing this selection button 4-5 for 2 seconds or longer. Operate the rotary switch 4-2 (blue adjustment), 4-3 (green adjustment), and 4-4 (red adjustment) to determine the color, and finally press the selection button 4-5 again for 2 seconds or longer. Then, the color change can be completed. The relationship between the color to be specified and the value input by the rotary switch may be adjusted by matching the dial designation position of each rotary switch with a numerical value corresponding to the desired color using a comparison table prepared in advance. The decision button 4-6 is a button used to decide the first color or the second color in the middle when a plurality of colors can be designated during the color change operation.

  Next, the internal configuration of the controller 4 will be described with reference to FIG. Reference numeral 7 denotes a synchronizing signal receiving circuit as a synchronizing signal receiving means, which is connected to the signal line 5 extending from the 16th light located at the last of the lights constituting the light emitting unit of the preceding light emitting unit, and emits light at the preceding stage. A synchronization signal output from the unit is received. At this time, the signal line 5 includes three signal lines (three-core cables) individually corresponding to the RGB color LEDs constituting the light 5, and includes an R (red) signal line and a G (green) signal. The line and the B (blue) signal line are connected to an OR circuit. The inputs from the three signal lines are ORed, and a synchronization signal is extracted from the calculation result. Since the synchronization signal is superimposed on the blinking drive signal for driving the light 5 to blink, each of the three signal lines is used to extract the synchronization signal from the blinking drive signal having the RGB color information. However, if an OR circuit is provided and OR operation is performed on the three signal lines, only the extraction process needs to be performed. When the synchronization signal receiving circuit 7 receives the synchronization signal from the preceding light emitting unit, the synchronization signal receiving circuit 7 outputs the synchronization signal to the synchronization signal output circuit 8 and also outputs it to the offset applying circuit 9. Upon receiving the synchronization signal, the offset applying circuit 9 outputs the offset value set by the start switch 4-4 to the blinking operation synchronizing means 10. The synchronization signal output circuit 8 outputs the synchronization signal received from the synchronization signal receiving circuit 7 toward the next-stage light emitting unit. Reference numeral 11 denotes control means, which reads out the blinking control pattern selected by the pattern changeover switch 4-1 from the storage unit 12 and outputs a display processing signal to the blinking drive circuit 13 as blinking drive means. The blinking drive circuit 13 receives the output signal from the control means 11, creates a blinking drive signal for driving the light emitter 3 of the light emitting unit 2 to blink, and outputs the created blinking drive signal to the light emitting unit 2. .

  When the flashing operation synchronization means 10 receives a signal relating to the offset value from the offset applying circuit 9, the flashing operation synchronization means 10 instructs the control means 11 to start the reading position of the flashing control pattern from the step corresponding to the offset value. give. While the apparatus is in an energized state, the control means 11 sequentially reads the blinking control pattern from the storage unit 12 in time series and executes display processing. During the execution, an input related to the offset value is generated from the offset applying circuit 9. Then, the reading position is changed from the step read at that time to the step corresponding to the input offset value, and the display process is resumed.

  Reference numeral 14 denotes a signal superimposing circuit serving as a signal superimposing means, which frequency-modulates and superimposes the synchronizing signal output from the synchronizing signal output circuit 8 on the blinking driving signal output from the blinking driving circuit 13 and superimposes the superimposed signal on the light emitting unit. Send to 2.

  Next, the signal superimposing process performed by the signal superimposing circuit 14 will be described in detail with reference to FIG. FIG. 4 shows a state in which when the blinking drive signal output from the blinking drive circuit 13 is a pulse signal wave that repeats red blinking at a constant period t1, the synchronizing signal is pulse-frequency modulated in the second period using this signal wave as a carrier wave. Show. The period of the modulated pulse signal wave changes to t2 where the synchronization signal is modulated. The blinking drive signal as a carrier wave is merely an example. In this case, since the carrier wave is a pulse wave, pulse frequency modulation is performed. In short, the blinking drive signal is subjected to frequency modulation processing. The modulated blinking drive signal is sent to the light emitting unit 2, and the light 3 of the light emitting unit is driven to emit light by the blinking drive signal to emit illumination light. At the same time, the drive signal reaches the next light emitting unit through 16 lights connected in series, reaches the synchronizing signal receiving circuit of the next unit, and the synchronizing signal is demodulated in the circuit.

  By the way, in the signal superimposing process performed in the signal superimposing circuit 14, frequency modulation is applied to the period in which the light emission on-pulse exists in the blinking driving signal serving as a carrier wave. As shown in FIG. 4, when frequency modulation is applied to a period having a light emission on pulse, the sum of the pulse widths of the on pulse is the same before and after the modulation, and no change occurs. When frequency modulation is applied to a period where there is no on-pulse, it is necessary to start up a very short pulse at the boundary between the periods to distinguish the period changed by modulation, and there is no on-pulse before modulation. A phenomenon that is recognized as flickering by the human eye occurs due to an instantaneous pulse generated at a place where it has not been performed. In this regard, according to the applicant's test, the pulse width before modulation and the total pulse width of the modulated pulse (in the example of FIG. 4, the pulse width of the second period pulse before modulation and the modulation) It was confirmed that no flickering occurred if the sum of the pulse widths of the pulses existing in the subsequent period t2 + the period t2 was substantially equal. Therefore, in order to prevent unnecessary noise caused by the modulation process itself, the synchronization signal is always modulated with respect to the period having the light emission on pulse.

  Further, the signal superimposing process performed by the signal superimposing circuit 14 is such that the frequency modulation is performed by reducing the duty ratio to less than 100% for a cycle in which the on / off duty ratio in the blinking drive signal serving as a carrier wave is 100%. Yes. As shown in FIG. 6, when frequency modulation is applied to the period occupied by the light emission on-pulse throughout one period, a very short pulse falls at the boundary between the periods in order to distinguish the period changed by the modulation. There is a need, and a phenomenon that is recognized as flickering to the human eye occurs due to the instantaneous pulse itself and the change in the total of the pulse width before and after modulation. Therefore, as shown in FIG. 6 (b), frequency modulation is applied to a cycle with an on / off duty ratio of 100% after light emission is turned off for a predetermined time in advance. By doing so, it is not necessary to drop the pulse for distinguishing the period from one another, and at the same time, there is no change in the sum of the pulse widths before and after the modulation, thereby preventing unnecessary noise caused by the modulation process itself. It is.

  Next, the operation of this embodiment will be described with reference to FIG. FIG. 7A shows blinking control pattern data, and one display sequence is divided into three steps. The present invention is characterized in that the reading start position of the blinking control pattern data is changed in accordance with the offset value set in the light emitting unit, and the offset value set as shown in FIG. 7A is zero. If so, start reading data from step 1 which is the head of one display sequence. If it is plus 1, start reading data from the step immediately before step 1 (ie, step 3). For example, data reading is started from step 2. The synchronization signal is always output in step 1. In FIG. 7B, three light emitting units are connected in series, an offset 0 is set for the first light emitting unit 1, an offset +1 is set for the middle light emitting unit 2, and an offset +1 is set for the last light emitting unit 3. The timing chart in the case of making light emission blink by the blink control pattern data is shown. As shown in the figure, step 1 is first executed in the light emitting unit 1 in which the offset 0 is set, and at the same time, a synchronization signal is output toward the light emitting unit 2. In the light emitting unit 2 that has received this synchronization signal, since the offset +1 is set in the own unit, Step 3 that is the step immediately before Step 1 is executed, and when Step 1 is subsequently executed, the light emitting unit 3 is executed. A sync signal is output toward. The light emitting unit 3 that has received this synchronization signal executes step 3 which is the step immediately before step 1 since the offset +1 is set for the unit. This expresses a movement in which red flashing is performed in order from the light emitting unit 1 to the light emitting unit 3.

  Next, another operation of the present embodiment will be described with reference to FIG. FIG. 8 (a) shows one display sequence of the flashing operation of light emission. With this, the color is changed one after another in the order of “red”, “orange”, “yellow”, “green”, “blue”, “indigo”, and “purple”. A blinking action is performed. In this case, one display sequence is divided into seven steps, and the synchronization signal is output in step 1. In FIG. 8B, seven light emitting units are connected in series, the first light emitting unit 1 is offset 0, the next light emitting unit 2 is offset −1, the next light emitting unit 3 is offset −1, and the next light emitting unit 4 is. Is a timing chart when offset-1 is set, offset + 1 is set for the next light-emitting unit 5, offset + 1 is set for the next light-emitting unit 6, and offset + 1 is set for the last light-emitting unit 7. FIG. As shown in the figure, step 1 is first executed in the light emitting unit 1 in which the offset 0 is set, and at the same time, a synchronization signal is output toward the light emitting unit 2. In the light emitting unit 2 that has received this synchronization signal, since the offset −1 is set in the own unit, step 2 that is a step after step 1 is executed, and then step 7 is executed sequentially until step 7 again. When 1 is executed, a synchronization signal is output to the light emitting unit 3. The light emitting unit 3 that has received this synchronization signal executes step 2 that is a step after step 1 since offset −1 is set in the own unit, and then sequentially executes step 7 until step 7 again. When 1 is executed, a synchronization signal is output to the light emitting unit 4. In the light emitting unit 4 that has received this synchronization signal, since the offset −1 is set in the own unit, step 2 that is a step after step 1 is executed, and then step 7 is executed sequentially until step 7 again. When 1 is executed, a synchronization signal is output to the light emitting unit 5. In the light emitting unit 5 that has received this synchronization signal, since the offset +1 is set in the self unit, step 7 that is the step immediately before step 1 is executed, and when step 1 is subsequently executed, the light emitting unit 6 is executed. A sync signal is output toward. In the light emitting unit 6 that has received this synchronization signal, since the offset +1 is set in its own unit, Step 7 which is the step immediately before Step 1 is executed, and when Step 1 is executed subsequently, the light emitting unit 7 is executed. A sync signal is output toward. The light emitting unit 7 that has received this synchronization signal executes step 7 which is the step immediately before step 1 since the offset +1 is set for the unit. As described above, it is possible to express a movement in which a specific color opens from the light emitting unit 4 that is the center of the seven light emitting units connected to the left and right ends.

(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIG. Since the overall configuration of the light emitting device (FIG. 1) and the switch arrangement configuration of the controller 4 (FIG. 2) are the same as those in the first embodiment, description thereof will be omitted.

  As shown in FIG. 9, in the second embodiment, “communication signal receiving circuit 20” and “communication signal output circuit 22” are replaced with “synchronization signal receiving circuit 7” and “synchronization signal output circuit 8” of the first embodiment. Provided. The communication signal receiving circuit 20 is connected to the signal line 5 extending from the 16th light located at the tail of the lights constituting the light emitting unit of the preceding light emitting unit, and is output from the preceding light emitting unit. Receive a signal. This communication signal includes the switch setting contents and synchronization signal set by the pattern selector switch, brightness selector switch, speed selector switch, start switch, selection button, and enter button in the previous stage light emitting unit. The receiving circuit 20 outputs a synchronization signal among the received communication signals to the offset applying circuit 9, and outputs setting contents regarding the display effect and display mode set by each switch to the reception data setting means 21. Since the operation of the offset applying circuit 9 is the same as that of the first embodiment, the description thereof is omitted. When the reception data setting means 21 receives a signal from the communication signal receiving circuit 20, the reception data setting means 21 sets the setting content in the self-luminous unit. The communication signal output circuit 22 receives the output signal from the communication signal receiving circuit 20 and outputs it to the signal superimposing circuit 14.

  In the signal superimposing circuit 14, as in the first embodiment, the communication signal output from the communication signal output circuit 22 is frequency-modulated and superimposed on the blinking drive signal output from the blinking drive circuit 13, and the superimposed signal is output. Send to the light emitting unit 2. The specific superimposition processing method at this time is different from the first embodiment except that the synchronization signal to be frequency-modulated is 1 bit, but the second embodiment is a plurality of bits such as 8 bits. Of course, there is no change in the point that the modulation processing is performed for the period in which the light emission on-pulse exists in the blinking drive signal of the carrier wave.
