This lighting design work is performed using application software for lighting design (hereinafter abbreviated as lighting design application).

First, the lighting design application reads drawing data of a real space (baseball stadium) and obtains position information of the lighting tower from the read drawing data. Further, the lighting design application acquires position information of each of the plurality of lighting devices B1 installed in the lighting tower. Note that the position information of each of the lighting tower and the plurality of lighting devices B1 is expressed by a three-dimensional orthogonal coordinate system having an arbitrary position in real space as the origin. However, the xy plane is the horizontal plane.

In addition, the lighting design application uses the light distribution data of the lighting device B1 to be used (for example, light distribution data in IES format: IESNA:LM-63-2002/1995), and selects an arbitrary irradiation point (for example, a position on the ground). ) The direction (vertical angle) of each of the plurality of illumination devices B1 is adjusted so as to irradiate the beam. Then, the lighting design application calculates the illuminance distribution of the irradiation surface (for example, the ground) based on the light distribution data of the plurality of lighting devices B1 and information on each irradiation point.

Further, the lighting design application adjusts the position of the irradiation point of each lighting device B1 (orientation of the lighting device B1) until the calculated illuminance distribution matches the required illuminance distribution in the real space.

(2-9) Operation of the lighting control system The lighting control system A1 operates in a first control mode that controls the lighting device B1 in the real space, a second control mode that controls the model BM1 of the lighting device B1 in the virtual space, and a second control mode that controls the model BM1 of the lighting device B1 in the virtual space. The third control mode synchronizes the first control mode and the second control mode.

(2-9-1) First Control Mode The first control mode of the lighting control system A1 is a control mode executed by the control device 1.

For example, the control device 1 starts the first control mode when a trigger signal is input from the outside. First, the control device 1 reads control data for the first control mode from the storage device 4. The control data for the first control mode includes control data for base lighting that illuminates the ground and spectator seats while the match is in progress, and a lighting tower that resembles an electronic bulletin board when the match is stopped (time for changes of offense and defense, etc.) and control data for spatial presentation to display characters, etc.

The communication device 2 transmits (relays) the DMX signal received from the control device 1 to the plurality of lighting devices B1 via the second communication cable Ls2. Each of the plurality of lighting devices B1 changes its operating state according to the DMX signal received from the communication device 2. For example, when the control data is control data for base lighting, each of the plurality of lighting devices B1 is turned on at a dimming level (for example, 100% to 90%) specified by the control data. In addition, the dimming level represents the brightness ratio (luminous flux ratio) when the rated brightness (luminous flux) of lighting device B1 when turned on is 100% and the brightness when it is turned off is 0%. .

First, the control section 52 receives control data generated by the data generation section 51. The control data for the second control mode separately controls the models BM1 of the plurality of lighting devices B1 placed in the virtual reality lighting space VL1 created with 3DCG, and displays characters on a lighting tower that looks like an electronic bulletin board. Contains control data for spatial presentation.

The control unit 52 controls the monitor device 6 to change the operating state of the illumination space VL1 created in 3DCG and the model BM1 of the plurality of illumination devices B1 based on the control data for the second control mode received from the data generation unit 51. A video signal (HDMI signal) is output to (see Figure 1). For example, as shown in FIG. 3A, the control unit 52 causes the letters "GO" to be displayed on the model BM1 of the lighting device B1 installed on the lighting tower behind the outfield seats. Further, as shown in FIG. 3B, the control unit 52 displays the number "3", which is the batter's jersey number, on the model BM1 of the lighting device B1 installed in the lighting tower behind the infield seats and the left field outfield seats. let However, these display contents are only examples.

(2-9-3) Third Control Mode The third control mode of the lighting control system A1 is a control mode executed by the control device 1 and the control unit 52 of the virtual playback device C1.

For example, the control device 1 starts the third control mode when a trigger signal is input from the outside. First, the control device 1 reads control data for the third control mode from the storage device 4. The control data for the third control mode is common to the control data for spatial presentation in the first control mode.

The control device 1 transmits the control data for the third control mode read from the storage device 4 to the control unit 52 and the communication device 2 using a DMX signal. The communication device 2 transmits (relays) the DMX signal received from the control device 1 to the plurality of lighting devices B1 via the second communication cable Ls2. The plurality of lighting devices B1 display characters, figures, symbols, etc. as still images or moving images by turning on or off at a dimming level specified by the control data.

Based on the control data for the third control mode received from the control device 1, the control unit 52 causes the monitor device 6 to change the operating state of the illumination space VL1 created by 3DCG and the model BM1 of the plurality of lighting devices B1. Outputs a video signal. At this time, the control unit 52 refers to the time code included in the control data, and synchronizes the timing of outputting the video signal to the monitor device 6 with the control timing of the plurality of lighting devices B1 based on the time code.

Thus, in the third control mode, the lighting control system A1 can synchronize and control the lighting device B1 in the real space and the model BM1 of the lighting device B1 in the virtual reality lighting space VL1.
