  In step 504, the communication signal is received by the units (1, 2) and (2, 1). In step 505, the control units of the unlit units (1, 2) and (2, 1) are The control signal generated according to rule 4 is sent to its own LED. In step 506, units (1, 2) and (2, 1) are lit yellow.

FIG. 6 is a flowchart showing the operation of the present system corresponding to the moving person indicated by 302. In step 601, the photosensor of the unit (3, 3) detects the person 302 and sends a detection signal to the control unit. In step 602, the control unit of the unit (3, 3) generates an LED control signal and a communication signal, the control signal is sent to its own LED, and the communication signal is the unit (2, 3), (3, 2), ( 3, 4) and (4, 3). In step 603, the LED of the unit (3, 3) is lit red.

  In step 604, each unit whose communication signal is adjacent to unit (3, 3) receives the communication signal. In step 605, the control unit of units (2, 3) and (3, 2) that are lit in yellow 4 generates a control signal according to rule 5 and sends it to its own LED. In step 606, the units (2, 3) and (3, 2) are lit in green.

  In step 607, the control unit of the unlit units (3, 4) and (4, 3) generates a control signal according to rule 4 in FIG. 4 and sends it to its own LED. In step 608, units (3, 4) and (4, 3) are lit yellow.

  FIG. 7 is a flowchart showing the operation of the present system corresponding to the moving person shown at 303.

  In this way, it is possible to realize lighting that reacts interactively to a person moving on the floor surface by simply arranging the lighting units described so far in a matrix without introducing a central control device that performs complex calculations. Furthermore, even when the lighting area is extended to the corridor connected to the floor, it is possible to cope with the same configuration without changing the program stored in each unit by arranging the units having the same configuration next to the already installed units. For example, in FIG. 3, if a corridor extends downward from the unit (7, 1) (8, 1) in the drawing, the unit (7, 0) (8, 1) is transferred to the unit (7, 1) (8, 1). 0) (7, -1) (8, -1) ... (7, -n) (8, -n). In this way, the central control has an effect that the expansion beyond the management area where the design is re-executed can be easily realized. Furthermore, when the subject of sensing is a person as in the present embodiment, each sensing signal stays in the vicinity of the local area, and there is an advantage that personal information is not collected as action history.

FIG. 11 is a schematic structural diagram of an electrical decoration panel employed in Example 2.
The sensor unit 1102 and the display unit 1103 have a two-stage configuration of a first layer 1101 in which the display unit 1103 is arranged in a matrix, a second layer 1104 in which the control unit 1105 and the communication unit 1106 are arranged. Reference numeral 1107 is an external view of the entire panel generated by superimposing the first layer and the second layer, as viewed from the side, and a power terminal 1108 is provided on the lower surface.

  Here, a contact sensor (photo reflector) and a temperature sensor are used as the sensor means 1102. When an object touches the panel, the contact is recognized by reflection of light output from the sensor itself. It also detects the temperature of the touched object.

  The display means 103 employs LEDs. Here, the display means emits light in response to a control signal from the control means 105 provided in the second layer. The control means 105 employs an FPGA (Field Programmable Gate Array), and is mounted with a pulse width modulation (PWM) current control circuit, an arithmetic circuit, and an SRAM (Static Random Access Memory).

  The communication means 106 employs infrared communication, and can communicate only with the communication means provided on the adjacent panel and facing each other.

  FIG. 12 is a diagram showing a state of constructing the panel. Five illumination panels 1201 to 1205 are constructed on a panel base 1200 provided with a plurality of mounting holes 1206 incorporating power supply terminals. By inserting the panel into the mounting hole in the base, the position is determined and power is supplied. In such a system, it is only necessary to fit from above, so no wiring is required, and installation is very easy.

  FIG. 13 is a perspective view showing only the second layer of the constructed panel. As shown in the facing portion 1301, the communication means of adjacent panels face each other, and infrared communication is possible. When metal terminals are used as in wired communication, poor contact is likely to occur, and infrared has the advantage of certainty.

  FIG. 14 is a block diagram showing a configuration of the electrical decoration panel. The temperature sensor 1401, the photo reflector 1402, the LED 1403, the control unit 1404, the memory 1408, the microcomputer 1409, and the infrared communication unit 1410 are configured.

  A temperature sensor 1401 and a photo reflector 1402 are provided as sensors. When an object comes into contact with the unit, the contact is recognized by reflection of light output from the photoreflector itself, and a signal is sent to the control means such as Sensor (x, y) = on / off. Further, the temperature of the touched object is also detected, and the Celsius temperature is transmitted to the control means such that Temp (x, y) = 23. Here, a temperature sensor and a photo reflector are used as sensors, but the present invention is not limited to these sensors, and the gist of the present invention is to detect the surrounding environment such as a light intensity sensor, a wind sensor, a humidity sensor, and an atmospheric pressure sensor. Any sensor can be used as long as it fulfills the functions along the line.

  The control unit 1404 is an FPGA on which a PWM current control circuit 1405, an arithmetic circuit 1406, and an SRAM 1407 are mounted. Here, the SRAM 1407 stores image data and lighting patterns to be expressed.

  The memory 1408 is a flash ROM, and supplies data for program rewriting to the microcomputer 1409. The microcomputer 1409 refers to the data for rewriting, programs an image or lighting pattern expressed by the illumination panel, and writes it in the SRAM 1407.

An area for holding color information of the LED 1403 is in the SRAM, and is specified in the format LED (x, y) = (R, G, B). R, G, and B are values from 0 to 255, and a maximum of 256 × 256 × 256 = 16.7 million colors can be specified.
If it is 0, the color will not light up. It is lit at 255 with maximum intensity. The brightness is controlled by the PWM current control circuit based on the numerical value of LED ().

FIG. 15 is a diagram showing a first layer in a peripheral portion of the sensor 1501 that detects an object.
Nine LEDs from A to I shown at 1502 are shown.

  When the sensor 1501 detects the influence, only the adjacent LEDs A, B, H, and I are affected. The color development in the next cycle of LED I is determined by a function of the current color of adjacent LEDs A-H. In this way, the influence of the sensor 1501 is propagated throughout the entire cycle, such as sensor 1501 → I → E →.

  FIG. 16 is a flowchart showing the operation of one cycle. In step 1601, the color information of the LED of the side in contact with the own unit is acquired from the adjacent unit. In step 1602, the LED information of each adjacent unit is stored in the memory. The operation described in the frame of step 1603 proceeds simultaneously for all sensors and LEDs. In step 1604, it is checked whether all the sensors recognize the object. If “not recognized”, that is, if Sensor (x, y) = OFF, the step for the sensor is completed. If “recognized”, that is, Sensor (x, y) = ON, the process proceeds to step 1605 to add a predetermined value to the R component of the adjacent LED according to the value of the temperature sensor. Here, a predetermined value is added to the RGB R component, but step 1605 can be arbitrarily set by the user by changing the program.

The steps for the LED will be described. In step 1606, color information of eight adjacent LEDs is acquired. Next, in step 1607, the color of the own LED is determined from the color information of the adjacent LED according to the set algorithm f. LED () is formulated as follows.
LED (x, y) = f {LED (1,1) ... LED (m, n)}
Here, LED (1,1)... LED (m, n) is all LEDs adjacent to the own LED. The algorithm f set here can be arbitrarily set by the user by changing the program.

  When the steps described in the frame of 1603 are finished, in step 1608, information on each LED () variable is transferred to the PWM current control circuit and displayed as the LED color. Although it is one cycle as described above, the color of the LED of the own panel is changed in cooperation with the neighboring panel by repeating at about 30 times / second to show the movement of the illumination smoothly. Here, the cycle is set to 30 times / second, but the cycle of the present invention is not limited to this, and may be set to a longer cycle for production, or conversely, a short cycle may be set to the limit of the circuit capability.
