<< First Embodiment >>
[Overall Configuration of Variable Lighting Device 100]
First, the configuration of the variable illumination device 100 according to the first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 1, the variable illumination device 100 includes an illumination device 20 and a controller (control device) 30.

  The illumination device 20 includes a variable control unit 10, a pan motor 15, a tilt motor 16, a focus motor 17, a light source 18, a left and right rotating unit 21, an arm 22, a hood 23, and the like. The illuminating device 20 uses an LED as the light source 18 and drives and controls the pan motor 15, the tilt motor 16, and the focus motor 17 based on a toning instruction signal (DALI signal) transmitted from the controller 30.

  The left-right rotation unit 21 is connected to, for example, a ceiling fixing unit, and includes a variable control unit 10 and a pan motor 15. The left-right rotating unit 21 holds the arm 22 and rotates in the direction of the Pan arrow shown in FIG. 1 by driving the pan motor 15. Thereby, the illumination direction of the illuminating device 20 pans left and right.

  The arm 22 is fixed to the lower side of the left and right rotating unit 21 and includes a tilt motor 16. The arm 22 holds the hood 23 and rotates the hood 23 in the direction of the Tilt arrow shown in FIG. 1 by driving the tilt motor 16. Thereby, the illumination direction of the illuminating device 20 tilts up and down (Tilt).

  The hood 23 is held by an arm 22 and includes a focus motor 17 and a light source 18. The hood 23 moves the light source 18 in the direction of the Zoom arrow shown in FIG. 1 by driving the focus motor 17. Thereby, the focal distance of the illuminating device 20 zooms up (Zoom Up) or zooms down (Zoom Down).

  The controller 30 is, for example, a notebook computer, and includes a housing 31, a display unit 32, an input unit (for example, a mouse) 33, and the like. When the user operates the input unit 33 and designates coordinates of the toning control screen α displayed on the display unit 32, the controller 30 generates a DALI signal corresponding to the coordinate designation, and uses the generated DALI signal as the lighting device 20. Send to. The controller 30 may be a tablet terminal or a desktop personal computer.

  For example, when the controller 30 transmits a DALI signal corresponding to the coordinate designation of the first region of the toning control screen α to the lighting device 20, the variable control unit 10 performs the pan motor 15 and the tilt based on the DALI signal. Drive control of the motor 16 is performed. For example, when the controller 30 transmits a DALI signal corresponding to the coordinate designation of the second region of the toning control screen α to the lighting device 20, the variable control unit 10 performs the focus motor based on the DALI signal. 17 is driven and controlled. Thereby, in the variable illumination device 100, the illumination direction (pan / tilt) and the focal length (zoom) of the illumination device can be changed.

[Toning control screen]
As described above, the toning control screen α is displayed on the display unit 32 of the controller 30. Here, with reference to FIG. 2, a chromaticity diagram based on the CIE (International Lighting Commission) -XYZ color system, which is an example of the toning control screen α, will be described.

  As shown in FIG. 2, the chromaticity diagram based on the CIE-XYZ color system has a substantially bell shape, and the user can specify the hue and saturation of the light source based on the chromaticity diagram. The X axis of chromaticity coordinates represents the ratio of red (R), and the Y axis of chromaticity coordinates represents the ratio of green (G).

  The center of the chromaticity diagram (white point) has the lowest saturation, and the saturation increases from the center of the chromaticity diagram toward the periphery of the chromaticity diagram, and the periphery of the chromaticity diagram has the highest saturation. Become. Further, the hue changes in the order of red → orange → yellow → green → blue → indigo → blue purple corresponding to a portion curved in a bell shape. The periphery of the chromaticity diagram represents monochromatic light having a wavelength of 380 nm to 780 nm (blue purple to red), and the inner side of the chromaticity diagram represents multicolor light that is a combination of monochromatic lights.

  As the X-axis value increases, the ratio of red (R) increases, and as the X-axis value decreases, the ratio of blue (B) increases. Further, as the Y-axis value increases, the green (G) ratio increases, and as the Y-axis value decreases, the blue (B) ratio increases. The ratio of B (blue) is a value obtained by subtracting from 1 the sum of the ratio of red (R) and the ratio of green (G).

  In the variable illumination device 100 according to the present embodiment, when a user designates coordinates in a chromaticity diagram based on the CIE-XYZ color system, a DALI signal corresponding to the coordinate designation is transmitted from the controller 30 to the variable control unit 10. The variable control unit 10 controls the driving of the pan motor 15, the tilt motor 16, and the focus motor 17 based on the DALI signal.

  Although details will be described later, for example, when the user designates predetermined coordinates in a range (first range) of red (R) to green (G) (or green (G) to red (R)) in the chromaticity diagram, A DALI signal corresponding to the coordinate designation of the first range is transmitted from the controller 30 to the variable control unit 10, and the variable control unit 10 drives and controls the pan motor 15. Further, for example, when the user designates predetermined coordinates in the range (second range) of green (G) to blue (B) (or blue (B) to green (G)) in the chromaticity diagram, A DALI signal corresponding to the coordinate designation is transmitted from the controller 30 to the variable control unit 10, and the variable control unit 10 drives and controls the tilt motor 16. For example, when the user designates predetermined coordinates in a range (third range) of blue (B) to red (R) (or red (R) to blue (B)) in the chromaticity diagram, A DALI signal corresponding to the coordinate designation is transmitted from the controller 30 to the variable control unit 10, and the variable control unit 10 drives and controls the focus motor 17.

  The toning control screen α is not limited to a chromaticity diagram based on the CIE-XYZ color system, and may be any screen that allows the user to recognize changes in hue and saturation.

[Configuration of Lighting Device 20 and Controller 30]
Next, an example of the configuration of the illumination device 20 and the controller 30 will be described with reference to FIGS. 3 and 4.

  FIG. 3 is a block diagram illustrating configurations of the lighting device 20 and the controller 30.

  As illustrated in FIG. 3, the controller 30 includes a DALI master 301 and the like, and the lighting device 20 includes a variable control unit 10, a pan motor 15, a tilt motor 16, a focus motor 17 and the like. The variable control unit 10 includes a control unit 11, a drive circuit unit 12, and the like. The drive circuit unit 12 includes a motor drive circuit 12-1, a motor drive circuit 12-2, a motor drive circuit 12-3, and the like.

  The DALI master 301 generates a DALI signal corresponding to the coordinate designation on the toning control screen, and transmits the generated DALI signal to the lighting device 20 (variable control unit 10). The DALI signal is a toning instruction signal and is generated based on, for example, a chromaticity diagram based on the above-described CIE-XYZ color system.

  The variable control unit 10 receives the DALI signal generated by the DALI master 301, and controls driving of the pan motor 15, the tilt motor 16, and the focus motor 17 based on the received DALI signal (for example, rotation direction, rotation speed, rotation). Position, etc.). Further, the variable control unit 10 receives the DALI signal generated by the DALI master 301, and not only controls the pan motor 15, the tilt motor 16, and the focus motor 17 based on the received DALI signal, but also adjusts the light source. It is also possible to control the light.

  The control unit 11 generates a control signal based on the DALI signal corresponding to the coordinate designation on the toning control screen, and outputs the control signal to the drive circuit unit 12. For example, the control unit 11 performs the drive control of the first control signal S1 for performing the drive control of the pan motor 15 and the drive control of the tilt motor 16 based on the DALI signal corresponding to the coordinate designation of the first area of the toning control screen. A second control signal S2 to be performed is generated, and the first control signal S1 and the second control signal S2 are output to the drive circuit unit 12. For example, the control unit 11 generates a third control signal S3 for performing drive control of the focus motor 17 based on the DALI signal corresponding to the coordinate designation of the second region of the toning control screen, The control signal S3 is output to the drive circuit unit 12.

  The first control signal S1, the second control signal S2, and the third control signal S3 include, for example, instructions on the rotation direction of each motor, instructions on the rotation speed of each motor, instructions on the rotation position of each motor, and the like. . For example, if the first control signal S1, the second control signal S2, and the third control signal S3 are positive, the rotation directions of the pan motor 15, the tilt motor 16, and the focus motor 17 rotate forward, and the first control signal S1 and the first control signal S1 If the 2 control signal S2 and the third control signal S3 are negative, the rotation directions of the pan motor 15, the tilt motor 16, and the focus motor 17 are reversed.

  The drive circuit unit 12 drives and controls the pan motor 15, the tilt motor 16, and the focus motor 17 based on the control signals (S 1, S 2, S 3) output from the control unit 11. The drive circuit unit 12 can also perform dimming control of the light source based on a control signal output from the control unit 11 (not shown).

  Specifically, the motor drive circuit 12-1 generates a first drive signal U1 based on the first control signal S1, and outputs the first drive signal U1 to the pan motor 15. Thereby, the pan motor 15 rotates and the illumination direction of the illuminating device 20 is adjusted to right and left. Further, the motor drive circuit 12-2 generates a second drive signal U2 based on the second control signal S2, and outputs the second drive signal U2 to the tilt motor 16. Thereby, the tilt motor 16 rotates and the illumination direction of the illuminating device 20 is adjusted up and down. The motor drive circuit 12-3 generates a third drive signal U3 based on the third control signal S3, and outputs the third drive signal U3 to the focus motor 17. Thereby, the focus motor 17 rotates and the focal distance of the illuminating device 20 is adjusted back and forth.

  FIG. 4 is a diagram illustrating an example of a hardware configuration of the controller 30.

  As shown in FIG. 4, the controller 30 includes a display unit 32, an input unit 33, a communication unit 34, a CPU (central processing unit) 35, a RAM (random access memory) 36, and a ROM (read only memory). 37, an HDD (hard disk drive) 38, and a bus 39 for connecting them. The bus 39 connects each unit and exchanges data with each other.

  The CPU 35 executes a control program stored in a storage area such as the RAM 36, the ROM 37, and the HDD 38. The RAM 36 is used as a working storage area for the CPU 35 to execute a program. The ROM 37 and the HDD 38 store programs executed by the CPU 35, various data used by the programs, and the like.

  The display unit 32 is, for example, a liquid crystal display or the like, and the toning control screen α is displayed on the display unit 32. The input unit 33 is, for example, a pointing device such as a mouse or a keyboard that receives an operation input from a user. The communication unit 34 transmits / receives data to / from the lighting device 20 and transmits, for example, a DALI signal to the lighting device 20. The controller 30 can also accept an operation input from the user via a touch panel or the like.

[Operation Method of Variable Lighting Device 100]
Next, with reference to FIG.5 and FIG.6, the operation method of the variable illuminating device 100 is demonstrated.

  FIG. 5 is a diagram illustrating an example of an operation screen of the controller 30.

  In the example shown in FIG. 5, the toning control screen α is divided into a first area 101, a second area 102, and a third area 103.

  When the toning control screen α, the first area 101, the second area 102, and the third area 103 are displayed in coordinates, the toning control screen α has coordinates (0, 0), coordinates (X3, 0), coordinates ( X3, Y3) and an area surrounded by coordinates (0, Y3). The first area 101 is an area surrounded by coordinates (0, 0), coordinates (X2, 0), coordinates (X2, Y2), and coordinates (0, Y2). The second area 102 is an area surrounded by coordinates (X2, 0), coordinates (X3, 0), coordinates (X3, Y3), and coordinates (X2, Y3). The third area 103 is an area surrounded by coordinates (0, Y2), coordinates (X3, Y2), coordinates (X3, Y3), and coordinates (0, Y3). The coordinate (X1,0) is the midpoint between the coordinate (X3,0) and the coordinate (0,0), and the coordinate (0, Y1) is the coordinate (0, Y3) and the coordinate (0,0). ).

  In addition, the initial position refers to the position of the illumination device 20 corresponding to the coordinates (X1, Y1) (right direction, left direction, upward direction, or downward direction) in pan / tilt control of the illumination device 20. In the zoom control of the illuminating device 20, the position of the illuminating device 20 corresponding to the coordinates (X2 to X3, Y1) (the position not moving in either the remote direction or the proximity direction) is indicated. .

  When the user clicks the mouse in the first area 101 at, for example, predetermined coordinates (X1, Ya1), the controller 30 transmits a DALI signal corresponding to the coordinate designation of the first area 101 to the variable control unit 10. Then, the variable control unit 10 generates a first control signal S1 for rotating the pan motor 15 in the reverse direction. The variable control unit 10 controls the driving of the pan motor 15 based on the first control signal S1. As a result, the left / right rotation unit 21 pans to the left, and the illumination direction of the illumination device 20 moves from the initial position direction to the left direction.

  In addition, when the user clicks the mouse in the first area 101 at, for example, predetermined coordinates (X1, Ya2), the controller 30 sends a DALI signal corresponding to the coordinate designation of the first area 101 to the variable control unit 10. The variable control unit 10 generates a first control signal S1 for rotating the pan motor 15 forward. The variable control unit 10 controls the driving of the pan motor 15 based on the first control signal S1. As a result, the left / right rotating unit 21 pans to the right and the illumination direction of the illumination device 20 moves from the initial position direction to the right direction.

  Further, when the user clicks the mouse in the first area 101 with, for example, predetermined coordinates (Xb1, Y1), the controller 30 sends a DALI signal corresponding to the coordinate designation of the first area 101 to the variable control unit 10. The variable control unit 10 generates a second control signal S2 for rotating the tilt motor 16 in the reverse direction. Further, the variable control unit 10 drives and controls the tilt motor 16 based on the second control signal S2. As a result, the hood 23 tilts and rotates downward, and the illumination direction of the illumination device 20 moves downward from the initial position direction.

  Further, when the user clicks the mouse in the first area 101 with, for example, predetermined coordinates (Xb1, Y1), the controller 30 sends a DALI signal corresponding to the coordinate designation of the first area 101 to the variable control unit 10. The variable control unit 10 generates a second control signal S2 for rotating the tilt motor 16 forward. Further, the variable control unit 10 drives and controls the tilt motor 16 based on the second control signal S2. As a result, the hood 23 tilts and rotates in the upward direction, and the illumination direction of the illumination device 20 moves upward from the initial position direction.

  In addition, when the user clicks the mouse in the second area 102 with, for example, predetermined coordinates (Xc1, Yc1), the controller 30 sends a DALI signal corresponding to the coordinate designation of the second area 102 to the variable control unit 10. The variable control unit 10 generates a third control signal S3 for rotating the focus motor 17 in the reverse direction. The variable control unit 10 controls driving of the focus motor 17 based on the third control signal S3. Thereby, the focal distance of the illuminating device 20 becomes shorter than the distance in an initial position, and zooms up (Zoom Up).

  Further, when the user clicks the mouse in the second area 102 with, for example, predetermined coordinates (Xc2, Yc2), the controller 30 sends a DALI signal corresponding to the coordinate designation of the second area 102 to the variable control unit 10. The variable control unit 10 generates a third control signal S3 for rotating the focus motor 17 forward. The variable control unit 10 controls driving of the focus motor 17 based on the third control signal S3. Thereby, the focal distance of the illuminating device 20 becomes longer than the distance in an initial position, and zooms down (ZoomDown).

  Further, when the user clicks the mouse in the third area 103 with, for example, predetermined coordinates (X11, Y11), the controller 30 sends a DALI signal corresponding to the coordinate designation in the third area 103 to the variable control unit 10. The variable control unit 10 generates a fourth control signal S4 for increasing the light amount of the light source 18 (not shown). In addition, the variable control unit 10 performs dimming control of the light source 18 based on the fourth control signal S4. Thereby, the light quantity of the illuminating device 20 increases gradually, and the illuminating device 20 becomes bright. The fourth control signal S4 includes, for example, an instruction of the light amount of the light source 18 and the like.

  In addition, when the user clicks the mouse in the third area 103 with, for example, predetermined coordinates (Xl2, Yl2), the controller 30 sends a DALI signal corresponding to the coordinate designation in the third area 103 to the variable control unit 10. The variable control unit 10 generates a fourth control signal S4 for reducing the light amount of the light source 18. In addition, the variable control unit 10 performs dimming control of the light source 18 based on the fourth control signal S4. Thereby, the light quantity of the illuminating device 20 reduces gradually, and the illuminating device 20 becomes dark.

  That is, in the example illustrated in FIG. 5, for example, in the first region 101, the user may, for example, have predetermined coordinates (X1, Ya1), predetermined coordinates (X1, Ya2), predetermined coordinates (Xb1, Y1), predetermined coordinates (Xb2, Y1). ), The lighting direction (pan / tilt) of the lighting device is controlled. In the second area 102, for example, the mouse is clicked at predetermined coordinates (Xc1, Yc1) and predetermined coordinates (Xc2, Yc2). Then, the focal length (zoom) of the lighting device is controlled, and in the third region 103, for example, when the mouse is clicked at predetermined coordinates (Xl1, Yl1) and predetermined coordinates (Xl2, Yl2), the light amount of the lighting device is controlled. Is done.

  In FIG. 5, the variable control unit 10 controls the illumination direction (pan / tilt) of the illumination device 20 based on the DALI signal corresponding to the coordinate designation of the first area 101, and designates the coordinates of the second area 102. One example is a case where the focal length (zoom) of the illumination device 20 is controlled based on the DALI signal corresponding to, and the light control of the illumination device 20 is controlled based on the DALI signal corresponding to the coordinate designation of the third region 103. However, the present invention is not limited to this. For example, the variable control unit 10 may control the illumination direction (pan / tilt) of the illumination device 20 based on the DALI signal corresponding to the coordinate designation of the second area 102, or the coordinate designation of the third area 103. The focal length (zoom) of the illumination device 20 may be controlled based on the DALI signal corresponding to.

  That is, a region for controlling the illumination direction (pan / tilt) of the illumination device 20, a region for controlling the focal length (zoom) of the illumination device 20, and a region for controlling the light control of the illumination device 20. The user can arbitrarily determine which area (for example, the first area 101, the second area 102, and the third area 103) is allocated. In the example illustrated in FIG. 5, an example in which the variable illumination device 100 controls pan / tilt / zoom and dimming of the illumination device 20 is described as an example. It is also possible to control only the pan / tilt / zoom of the device 20.

  As described above, the user can click on a predetermined area of the toning control screen α displayed on the display unit 32 with a mouse to perform a simple operation of panning and tilting the lighting device 20 and the lighting device 20. The focal length (zoom) can be controlled.

  FIG. 6 is a flowchart illustrating an example of a method for operating the variable illumination device 100.

  When the toning control screen α (see FIG. 5) is displayed on the display unit 32 of the controller 30, the user starts an operation.

  In step S <b> 71, the user uses the input unit (for example, mouse) 33, clicks a predetermined area on the toning control screen α, and designates coordinates (XY coordinates).

  In step S <b> 72, the controller 30 transmits a DALI signal corresponding to the coordinate designation of the toning control screen α by the user to the variable control unit 10.

  In step S73, the variable control unit 10 determines whether or not the received DALI signal corresponds to the first area 101 of the toning control screen α. When corresponding to the first region 101 (step S73 → Yes), the variable control unit 10 proceeds to the process of step S74. If it does not correspond to the first area 101 (step S73 → No), the variable control unit 10 proceeds to the process of step S76.

  In step S74, the variable control unit 10 generates a first control signal S1 based on the DALI signal corresponding to the X coordinate of the first region 101, and generates the first drive signal U1 based on the first control signal S1. The first drive signal U 1 is generated and output to the pan motor 15. Thereby, the pan motor 15 rotates and the illumination direction of the illuminating device 20 is adjusted to right and left.

  In step S75, the variable control unit 10 generates the second control signal S2 based on the DALI signal corresponding to the Y coordinate of the first region 101, and generates the second drive signal U2 based on the second control signal S2. The second drive signal U 2 is generated and output to the tilt motor 16. Thereby, the tilt motor 16 rotates and the illumination direction of the illuminating device 20 is adjusted up and down.

  In step S76, the variable control unit 10 determines whether or not the received DALI signal corresponds to the second region 102 of the toning control screen α. When corresponding to the second region 102 (step S76 → Yes), the variable control unit 10 proceeds to the process of step S77. When not corresponding to the 2nd field 102 (Step S76-> No), variable control part 10 progresses to processing of Step S78.

  In step S77, the variable control unit 10 generates a third control signal S3 based on the DALI signal corresponding to the Y coordinate of the second region 102, and generates the third drive signal U3 based on the third control signal S3. The third drive signal U 3 is generated and output to the focus motor 17. Thereby, the focus motor 17 rotates and the focal distance of the illuminating device 20 is adjusted back and forth.

  In step S78, the variable control unit 10 generates a fourth control signal S4 based on the DALI signal corresponding to the X coordinate of the third region 103, and generates the fourth drive signal U4 based on the fourth control signal S4. The fourth drive signal U 4 is generated and output to the light source 18. Thereby, the light quantity of the light source 18 changes and the brightness or darkness of the illuminating device 20 is adjusted.

  The operation of the variable illumination device 100 shown in FIG.

  According to the variable illumination device 100 according to the present embodiment, a toning instruction signal (DALI signal) for controlling toning of the illumination device is used for controlling pan / tilt / zoom of the illumination device. . Therefore, it is possible to provide the variable illumination device 100 that can control the illumination direction and focal length of the illumination device using the DALI system. In addition, since it is not necessary to prepare a dedicated remote controller or the like to construct a lighting system, the inexpensive variable lighting device 100 can be provided.

[Modification of operation method]
Next, with reference to FIGS. 7 and 8, a method of operating the variable illumination device 100 different from FIGS. 5 and 6 will be described.

  FIG. 7 is a diagram illustrating an example of a method for operating the variable illumination device 100.

  In the example shown in FIG. 7, the toning control screen α is not divided into the first area 101, the second area 102, and the third area 103 as in the example shown in FIG. Corresponding to the range, the illumination direction (pan / tilt) of the illumination device 20 and the focal length (zoom) of the illumination device 20 are controlled. That is, in the example shown in FIG. 5, the DALI signal is assigned to each control regardless of the chromaticity diagram, but in the example shown in FIG. 7, the DALI signal is assigned to each control in association with the chromaticity diagram. Yes.

  In addition, the initial position is a midpoint between the predetermined coordinates whose hue is red (R) and the predetermined coordinates whose hue is green (G) in the pan control of the lighting device 20 (the hue is substantially yellow). It refers to the position of the illumination device 20 corresponding to (predetermined coordinates) (the position that has not moved in either the right direction or the left direction). Further, in the tilt control of the lighting device 20, the center point (predetermined coordinates whose hue is substantially blue-green) between the predetermined coordinates whose hue is green (G) and the predetermined coordinates whose hue is blue (B). It refers to the position of the corresponding lighting device 20 (the position that has not moved in either the upward direction or the downward direction). Further, in the zoom control of the lighting device 20, it corresponds to the midpoint (predetermined coordinates whose hue is substantially pink) between the predetermined coordinates whose hue is blue (B) and the predetermined coordinates whose hue is red (R). This refers to the position of the lighting device 20 (the position that has not moved in either the remote direction or the proximity direction).

  When the user clicks the mouse at a predetermined coordinate in the first range D (for example, a range from a predetermined coordinate in which the hue is yellow to a predetermined coordinate in which the hue is green), the controller 30 specifies the coordinates of the first range D. Is transmitted to the variable control unit 10, and the variable control unit 10 generates a first control signal S1 for causing the pan motor 15 to rotate forward. The variable control unit 10 controls the driving of the pan motor 15 based on the first control signal S1. As a result, the left / right rotating unit 21 pans to the right and the illumination direction of the illumination device 20 moves from the initial position direction to the right direction.

  In addition, when the user clicks the mouse at a predetermined coordinate in the first range D (for example, a range from a predetermined coordinate in which the hue is yellow to a predetermined coordinate in which the hue is red), the controller 30 A DALI signal corresponding to the coordinate designation is transmitted to the variable control unit 10, and the variable control unit 10 generates a first control signal S1 for rotating the pan motor 15 in the reverse direction. The variable control unit 10 controls the driving of the pan motor 15 based on the first control signal S1. As a result, the left / right rotation unit 21 pans to the left, and the illumination direction of the illumination device 20 moves from the initial position direction to the left direction.

  When the user clicks the mouse at a predetermined coordinate in the second range E (for example, a range from a predetermined coordinate whose hue is blue-green to a predetermined coordinate whose hue is green), the controller 30 causes the second range E to be A DALI signal corresponding to the coordinate designation is transmitted to the variable control unit 10, and the variable control unit 10 generates a second control signal S2 for rotating the tilt motor 16 in the reverse direction. Further, the variable control unit 10 drives and controls the tilt motor 16 based on the second control signal S2. As a result, the hood 23 tilts and rotates downward, and the illumination direction of the illumination device 20 moves downward from the initial position direction.

  When the user clicks the mouse at a predetermined coordinate in the second range E (for example, a range from a predetermined coordinate whose hue is blue-green to a predetermined coordinate whose hue is blue), the controller 30 causes the second range E to be A DALI signal corresponding to the coordinate designation is transmitted to the variable control unit 10, and the variable control unit 10 generates a second control signal S <b> 2 for rotating the tilt motor 16 forward. Further, the variable control unit 10 drives and controls the tilt motor 16 based on the second control signal S2. As a result, the hood 23 tilts and rotates in the upward direction, and the illumination direction of the illumination device 20 moves upward from the initial position direction.

  In addition, when the user clicks the mouse at a predetermined coordinate in the third range F (for example, a range from a predetermined coordinate in which the hue is pink to a predetermined coordinate in which the hue is red), the controller 30 A DALI signal corresponding to the coordinate designation is transmitted to the variable control unit 10, and the variable control unit 10 generates a third control signal S 3 for causing the focus motor 17 to rotate forward. The variable control unit 10 controls driving of the focus motor 17 based on the third control signal S3. Thereby, the focal distance of the illuminating device 20 becomes longer than the distance in an initial position, and zooms down (ZoomDown).
