Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. For convenience of explanation, components shown in the drawings may be exaggerated, omitted, or schematically represented.

The present invention relates to a lighting device that allows one or more lighting lamps to simultaneously illuminate a moving object according to the movement of the moving object on the stage.

Figure 1 is a configuration diagram of a follow spot lighting device according to the present invention, Figure 2 shows follow spot lighting according to the present invention, and Figure 3 shows the movement of the spot point according to the movement of a moving object in follow spot lighting. .

The follow spot lighting device according to the present invention includes an illuminator 100 consisting of a lighting lamp, a camera, and a pan-tilt driver, and a controller 300 connected to the illuminator. For the follow spot, at least two illuminators may be installed. Here, the follow spot refers to grouping at least two or more fixtures and all grouped fixtures illuminating one point. At this time, when the light irradiation point is moved, all grouped illuminators follow and illuminate the moving light irradiation point.

Referring to the drawing, three lighting posts are installed at the edge of the stage, and illuminators (100-1, 100-2, 100-3) are installed on top of the lighting posts. The lighting post has a predetermined height (h).

The lighting device according to the present invention has three light irradiation modes. The light irradiation mode may include individual light irradiation mode, naked eye mode, and camera mode.

The individual light irradiation mode refers to selecting one of the illuminators installed at the edge of the stage to illuminate the light irradiation point. For example, the operator can see a moving object on the stage and manipulate the direction control lever of the controller to move the light irradiation position to follow the movement of the moving object.

The naked eye mode and camera mode are selected for follow spot lighting. Follow spot lighting groups at least two fixtures, and all of the grouped fixtures can illuminate one point, that is, a spot point.

The naked eye mode looks at the spot point illuminated on the stage that the operator is watching and uses the direction control lever of the controller to control the pan and tilt drivers of the grouped fixtures.

The camera mode controls the pan-tilt driver of the fixture by looking at the spot point displayed on the monitor screen that the operator is looking at and using the direction control lever of the controller.

In camera mode, grouped fixtures consist of one master fixture and slave fixtures driven to follow the spotpoint of the master fixture. The master illuminator can be changed to any one of the slave illuminators depending on the operator's selection. At this time, the previous master fixture is converted to a slave fixture. When a master fixture is selected, images captured from the master fixture's camera are displayed on the monitor screen.

Figure 4(a) shows the movement direction of the spot point according to the operation of the direction control lever in naked eye mode, and Figure 4(b) shows the movement direction of the spot point according to the operation of the direction control lever in camera mode. will be.

The naked eye mode and camera mode have different operating directions depending on the observation direction (viewpoint). For example, assuming that the operator is looking at a stage installed in front and a fixture is installed on the left side of the stage, when the naked eye mode is selected, the operator moves the direction control lever to the right or left to set the light irradiation point to the right. Or you can move it to the left. In contrast, when the camera mode is selected, the operator can view the image displayed on the monitor and manipulate the direction control lever to move the light irradiation point to the right or left. In Figure 4(b), when the object moves to the right on the monitor screen, the operator tilts the direction control lever to the right. According to this operation, the spot point moves anteriorly.

Figure 5 is a perspective view of an illuminator according to the present invention.

The illuminator 100 according to the present invention is installed on the top of a post TT having a predetermined height. The illuminator consists of a lighting lamp 110, a camera 120 installed on top of the lighting lamp, and a pan-tilt driver 130 that rotates the lighting lamp up, down, left and right.

A lighting lamp is installed on top of the pan-tilt driver, and a camera is installed on top of the lighting lamp 110. The camera 120 has an imaging direction that is the same as the light irradiation direction of the lighting lamp. The pan-tilt driver 130 is driven according to a control signal from the controller. When the pan-tilt driver is driven in a pan, the lighting lamp and the camera rotate left and right at the same time, and when driven in a tilt, the lighting lamp and the camera rotate. The cameras rotate up and down together.

Meanwhile, images captured from the camera are transmitted to a monitor connected to the controller. The spot point of the lighting lamp is always located in the center of the monitor screen.

Figure 6 shows the controller and peripheral configuration according to the present invention, and Figure 7 is a configuration diagram of the control circuit according to the present invention.

The controller 300 may include a main body 310, an image processing device 320, and a monitor 330. The main body 310 may be provided with a control circuit 311, a mode selection button 312, an illuminator selection button 313, a light quantity control lever 314, and a direction control lever 315.

The control circuit unit 311 may be provided with a control module for selecting a light irradiation mode, controlling the amount of light, and controlling the direction of the lighting lamp. The control circuit selects an illuminator and controls the light amount and light irradiation direction of the selected illuminator.

The operator can operate the mode selection button 312 to select one mode among individual light irradiation mode (single mode), naked eye mode (naked eye mode), and camera view mode. In addition, one fixture can be selected from among the fixtures installed on the stage by manipulating the fixture selection button 313, and the light amount of the selected fixture can be adjusted by raising or lowering the light amount control lever 314. Additionally, the direction of light irradiation of the lighting lamp and the imaging direction of the camera can be controlled by manipulating the direction control lever 315.

Figure 6 shows a monitor screen displayed in camera mode, and the monitor shows an object located in the center of the display screen.

The control circuit unit 311 according to the present invention includes a fixture control module 311-1, a mode selection module 311-2, a virtual coordinate storage module 311-3, and a data conversion module 311-4.

The fixture control module 311-1 receives direction control values from the direction control lever and controls the amount and direction of light of fixtures installed on the stage. The fixture control module may control individually selected fixtures or grouped fixtures.

The mode selection module 311-2 receives light irradiation mode selection from the operator. The light irradiation mode may be a single light irradiation mode, a naked eye mode, or a camera view mode.

The virtual coordinate storage module 311-3 creates and stores a virtual coordinate system of the stage. The virtual coordinate system may be an xyz coordinate system. The origin of the virtual coordinate system may be the location of the controller, the center of the stage, or the installation location of one of the fixtures. The coordinates of the fixture may be stored in the stored virtual coordinate system. For example, when the installation location of the first fixture is set to the origin (0,0,0), the coordinates of the first fixture may be stored as (0,0,h). Assuming that the second illuminator is spaced d meters to the right in the x-axis direction from the first illuminator, the coordinates of the second illuminator may be stored as (d, 0, h). Here, h refers to the height (meter) of the first and second illuminators.

The data conversion module 311-4 operates in camera mode, receives pan-tilt data of the master fixture, and generates pan-tilt data of the slave fixture using a previously stored virtual coordinate system.

Hereinafter, with reference to FIGS. 8 to 10, the data conversion method processed in the data conversion module according to the present invention will be described. The data conversion module runs in camera mode.

Figure 10 shows a method of acquiring pan-tilt data of a slave fixture based on pan-tilt data of the master fixture.

The method of acquiring pan-tilt data of a slave fixture according to the present invention includes the steps of receiving pan-tilt data of a master fixture directed to a spot point (S100), and calculating the spot point coordinates in a virtual coordinate system from the transmitted pan-tilt data of the master fixture. It includes a step of calculating (S200) and a step of generating pan-tilt data of the slave fixture based on the spot point coordinates and the slave fixture coordinates (S300).

Before the above steps, there may be a step of grouping fixtures installed at the edge of the stage and setting master fixtures and slave fixtures among the grouped fixtures.

In camera mode, the operator views the stage image on a monitor and controls fixtures according to the movement of objects displayed on the monitor. At this time, the direction control lever is linked with the master illuminator, and the movement of the spot point is controlled by manipulating the direction control lever.

1. Receiving pan-tilt data of the master illuminator toward the spot point (S100);

The operator can view the camera images installed on the master illuminator on the monitor. At this time, since the light irradiation direction of the lighting lamp installed in the illuminator and the imaging direction of the camera are the same, the center of the monitor screen always faces the spot point.

The data conversion module receives the pan-tilt data of the master fixture facing the spot point. Specifically, the pan-tilt data can be transmitted from the pan-tilt driver 130 of the fixture.

2. Calculating spot point coordinates on a virtual coordinate system from the transmitted pan-tilt data of the master illuminator (S200);

The coordinates of the spot point are calculated using the pan-tilt data of the master fixture and a previously stored virtual coordinate system.

Figure 8 shows calculating spot point coordinates on a virtual coordinate system from the pan-tilt data of the master illuminator.

The separation distance (dm) between the installation point of the master illuminator (100-1) and the spot point (sp) is calculated based on the height (h) and tilt data (θmt) of the master illuminator. In Figure 5(a), the separation distance (dm) between the installation position of the master illuminator and the spot point can be calculated from h·tan(θmt).

Next, in FIG. 5(b), the coordinates of the spot point (sp) on the virtual coordinate system are calculated based on the calculated separation distance (dm) and the fan data (θmp) of the master illuminator. The coordinates of the calculated spot point may be (x,y,0).

3. Generating pan-tilt data of the slave fixture based on the spot point coordinates and the slave fixture coordinates (S300);

The pan-tilt data of the slave fixture is calculated from the spot point coordinates and the slave fixture coordinates.

Figure 9 shows calculating pan-tilt data of a slave fixture based on the spot point coordinates and the coordinates of the slave fixture.

The coordinates of the slave fixture are stored in the virtual coordinate system, and the pan-tilt data of the slave fixture is calculated using the stored coordinates of the slave fixture and the coordinates of the spot point. As shown in FIG. 9(a), the tilt data (θst) of the slave illuminator is calculated using trigonometry applying the x-coordinate value and z-coordinate value between two spaced apart points. In addition, as shown in FIG. 9(b), the fan data (θsp) of the slave fixture is calculated using trigonometry using the x-coordinate and y-coordinate values between two spaced apart points.

The pan and tilt data of the slave fixture calculated in this way are transmitted to the pan and tilt driver of the slave fixture (100-2). In this embodiment, the calculation is made assuming that there is only one slave fixture, but if there are two or more slave fixtures, the pan-tilt data of the slave fixtures can be calculated in the same manner as above.

According to the present invention, several illuminators are sequentially manipulated to individually irradiate one point, that is, a spot point, and then these illuminators are grouped into one group.

In naked eye mode, the controller can simultaneously change the light irradiation position of grouped illuminators by changing the position of the spot point using the direction control lever. Naked Eye mode transmits different pan-tilt data to illuminate a spot point on each of the fixtures participating in the grouping.

In camera mode, you can set any one of the grouped fixtures as the master fixture, view the camera image mounted on the master fixture on the monitor, and change the position of the spot point. This camera mode can implement follow spot lighting by looking at the monitor image when the stage cannot be seen from the operator's field of view in naked eye mode.

The method of calculating the pan/tilt data of the slave fixture in the camera mode according to the embodiment described above may be implemented as a computer program and recorded on a computer-readable recording medium. Examples of computer-readable recording media may include semiconductor storage devices and optical data storage devices.

Above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical idea of the present invention.
