  Next, the setting process of the illumination light irradiation direction by the illumination system 10 will be described with reference to FIGS.

  When performing the setting work, the luminaire 14 to be set and the terminal 15 are connected in advance so as to enable wireless communication.

  First, the operator operates the terminal 15 and designates the position setting mode (step S100).

  The terminal 15 transmits a position setting mode signal to the luminaire 14, picks up an image by the image pickup unit 35 (step S101), and displays an image picked up by the image pickup unit 35 on the display unit 36 (step S102). At this time, the irradiated object 12 is displayed on the display unit 36 of the terminal 15, and the position of the terminal 15 and the image capturing direction of the image capturing unit 35 are adjusted so as to be displayed when not being displayed.

  On the other hand, when receiving the position setting mode signal from the terminal 15, the luminaire 14 emits the marker lights O, X, and Y from the marker light irradiation unit 23 (step S 200), and transmits the marker light irradiation signal to the terminal 15. .

  Further, the terminal 15 receives the marker light irradiation signal from the luminaire 14 and determines whether or not the marker lights O, X, and Y are recognized on the video imaged by the imaging unit 35 (step S103).

  Here, in the terminal 15, when the marker lights O, X, and Y are recognized on the video imaged by the imaging unit 35, the process proceeds to step S107. 3 shows an image displayed on the display unit 36 of the terminal 15, and when the marker lights O, X, and Y are recognized on the image captured by the imaging unit 35, the display unit 36 of the terminal 15 is used. The indicator lights O, X, and Y are displayed on the video displayed on the screen.

  In the terminal 15, when the marker lights O, X, and Y are not recognized on the video imaged by the imaging unit 35, an error signal is transmitted to the lighting fixture 14 (step S104).

  The luminaire 14 waits for reception of an error signal or a position setting mode end signal from the terminal 15 (steps S201 and S202).

  When the lighting device 14 receives an error signal from the terminal 15, it drives the pan driving unit 28 and the tilt driving unit 29, and the direction of the lamp body 21 of the lighting device 14, that is, the marker light emitted from the marker light irradiation unit 23 The irradiation directions of O, X, and Y are moved (step S203), and a marker light movement signal is transmitted to the terminal 15. The movement in the irradiation direction of the marker lights O, X, and Y may be, for example, moving in the horizontal direction at a predetermined tilt angle, and moving in the horizontal direction by changing the tilt angle.

  The terminal 15 receives the marker light movement signal from the luminaire 14 and monitors whether the marker lights O, X, and Y are recognized on the video imaged by the imaging unit 35 (step S105). When all the marker lights O, X, and Y are recognized on the video imaged by the imaging unit 35, a marker light recognition signal is transmitted to the luminaire 14 (step S106), and the process proceeds to step S107.

  When the luminaire 14 receives the marker light recognition signal from the terminal 15, it stops driving the pan driver 28 and the tilt driver 29 and stops the movement of the marker light O, X, Y in the irradiation direction (step S204). ).

  Further, in the processing unit 38 of the terminal 15, in step S107, that is, when the marker lights O, X, Y are recognized on the video imaged by the imaging unit 35 (YES side of step S103), or the marker light O, When the marker lights O, X, and Y are recognized on the image captured by the imaging unit 35 by the movement of the X and Y irradiation directions (YES side in step S105), the marker lights O, X, and Y on the image are recognized. Pixel coordinates O (x, y), X (x, y), Y (x, y) are specified, and each of these pixel coordinates O (x, y), X (x, y), Y (x, y) ) To obtain the pan angle θ and the tilt angle γ of the illumination direction (optical axis Z) of the illumination light of the luminaire 14 from the pixel coordinates (x, y) of the illumination target specified on the image. Is determined (step S107).

  After determining the conversion formula, the terminal 15 transmits a position setting mode end signal to the luminaire 14 (step S108).

  When receiving the position setting mode end signal from the terminal 15, the lighting fixture 14 stops the irradiation of the marker lights O, X, and Y from the marker light irradiation unit 23 (step S205). Note that the irradiation of the marker lights O, X, and Y from the marker light irradiation unit 23 may be continued until the end of the next target mode.

  Subsequently, the operator operates the terminal 15 and designates the target mode (step S110). In addition, you may transfer to target mode automatically after completion | finish of position setting mode.

  The terminal 15 accepts the designation of the irradiation target by the operator on the video displayed on the display unit 36 (step S111). For example, as shown in FIG. 4 or FIG. 5, the designation of the irradiation target P is accepted when the worker touches the vicinity of the center of the irradiated object 12.

  In the processing unit 38 of the terminal 15, the pixel coordinates (x, y) of the irradiation target P specified on the video are specified, and the illumination of the luminaire 14 is based on the conversion formula determined in the position setting mode described above. A pan angle θ and a tilt angle γ for moving the light irradiation direction are obtained (step S112), and these angle information signals are transmitted to the luminaire 14 (step S113).

  When receiving the angle information signal of the pan angle θ and the tilt angle γ from the terminal 15, the lighting fixture 14 drives the pan driving unit 28 and the tilt driving unit 29, and the direction of the lamp body 21 of the lighting fixture 14, that is, the marker light The irradiation direction of the marker lights O, X, and Y irradiated from the irradiation unit 23 is moved by the pan angle θ and the tilt angle γ (step S210), and the marker light movement signal is transmitted to the terminal 15.

  FIG. 4 shows an image displayed on the display unit 36 of the terminal 15, and when the marker light O is irradiated so as to coincide with the optical axis Z of the illumination light, the marker light O is applied to the irradiation target P on the image. Will move.

  FIG. 5 shows an image displayed on the display unit 36 of the terminal 15. When the marker light O is irradiated in parallel with the optical axis Z of the illumination light, the optical axis Z of the illumination light moves to the irradiation target P. Thus, the marker light O moves to the movement position O ′.

  When the terminal 15 receives the identification light movement signal from the lighting fixture 14, the terminal 15 transmits a target mode end signal to the lighting fixture 14 (step S114), and ends the target mode.

  The luminaire 14 receives the target mode end signal from the terminal 15 and ends the target mode.

  In this way, the irradiation direction of the illumination light from the luminaire 14 is set to the irradiated object 12 which is the irradiation target, and the illuminated object 12 is irradiated with the illumination light.

  As described above, according to the illumination system 10 of the present embodiment, the imaging unit 35 captures the irradiated object 12, and the image captured by the imaging unit 35 is displayed on the display unit 36 and displayed on the display unit 36. In order to control the luminaire 14 to move the irradiation direction of the illumination light to the designated irradiation target P by designating the irradiation target P on the image, the irradiation direction of the illumination light of the luminaire 14 is set as the irradiation target. It is possible to match with P easily and in a short time.

  In addition, by irradiating a plurality of marker lights O, X, Y corresponding to the illumination direction of the illumination light, the positions of the marker lights O, X, Y at a plurality of points on the image captured by the imaging unit 35, Based on the position of the designated irradiation target P, the lighting device 14 can be controlled to move the irradiation direction of the illumination light to the designated irradiation target P, and the irradiation direction of the illumination light of the lighting device 14 can be changed. The irradiation target P can be easily matched in a short time.

  Further, the marker light irradiation unit 23 may irradiate a plurality of marker lights at one time at a time. However, if one identification light is sequentially moved to each position and irradiated, the marker light is generated. Only one element is required, and the configuration can be simplified and inexpensive.

  Note that the imaging unit 35, the display unit 36, the designation unit 37, the processing unit 38, and the communication unit 39 may all be configured separately, or a part thereof may be integrated and the rest may be configured separately. .

  The function of the processing unit 38 may be provided on the lighting fixture 14 side.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
