<Lighting control system>
First, the lighting control system will be described with reference to FIG. 1A. FIG. 1A is a diagram showing an example of the configuration of the lighting control system S according to the embodiment. The lighting control system S shown in FIG. 1A shall be installed in a facility such as a stage or a television studio, for example.

As shown in FIG. 1A, the lighting control system S includes a control device 1, lighting devices 10-1 to 10-n, a node 20, a baton B, and an elevating device 30. The lighting control system S may have an arbitrary number of lighting devices 10-1 to 10-n, an arbitrary number of batons B, and an arbitrary number of nodes 20.

Further, in the following, the lighting devices 10-1 to 10-n are collectively referred to as a lighting device 10 when no particular distinction is required.

In the lighting control system S shown in FIG. 1A, between the control device 1 and the node 20 and between the control device 1 and the elevating device 30, for example, a predetermined Ethernet (registered trademark) or LAN (Local Area Network) is used. It is connected to be communicable by the network of. Further, the node 20 and the lighting device 10 are connected by a standard capable of bidirectional communication such as RDM which is an extension of DMX512.

The lighting device 10 is a lighting device capable of bidirectional communication with the node 20 and the control device 1 by a communication method according to the RDM standard which is an extension of DMX. Further, the lighting device 10 has a light source such as LEDs (Light Emitting Diodes), and changes the brightness, range, color, and the like according to a control signal to produce lighting in a studio, a stage, or the like.

Further, the lighting device 10 is a facility installed in an arbitrary space such as a television studio or a stage, and is installed in a baton B that suspends and supports the lighting device 10 or the like. Further, the lighting device 10 may be cascaded to each port of the node 20.

The baton B is supported by suspending the lighting device 10 and the node 20. The baton B moves up and down by the operation of the lifting device 30.

The node 20 is a distributor that distributes control information capable of bidirectional communication with the lighting device 10 and the control device 1 by a communication method according to the RDM standard which is an extension of the DMX512. Further, the node 20 is a relay device that relays communication between the control device 1 and the lighting device 10, and is realized by, for example, a device called a DMX node or an RDM node. Specifically, the node 20 communicates with the control device 1 or the like in a manner capable of bidirectional communication by a wired or wireless network such as Ethernet (registered trademark) or LAN.

The elevating device 30 raises or lowers the baton B by controlling the winding amount of the wire W connected to the baton B in response to the control signal from the control device 1. The baton B is not limited to supporting the lighting device 10, and may support an appliance such as a camera or a speaker.

The control device 1 is a control device capable of communicating a bidirectional control signal (for example, a control signal corresponding to the RDM standard) with the lighting device 10 via the node 20, and is generally a dimming table. It is a device called a control console or the like.

As shown in FIG. 1A, the control device 1 according to the embodiment performs dimming control for controlling the dimming of the lighting device 10 and elevating control for controlling the elevating and lowering of the baton B via the elevating device 30.

Specifically, when performing dimming control, the control device 1 receives an operation command for the lighting device 10 from a user (for example, an operator who operates the control device 1), and receives a control address assigned to the lighting device 10. A control signal including the control signal is generated, and the control signal is transmitted to the node 20. The node 20 converts the control signal received from the control device 1 into, for example, a signal (RDM signal) according to the RDM standard, and outputs the control signal to the lighting device 10 indicated by the control address. As a result, the dimming control of the lighting device 10 is performed. As described above, the control device 1 remotely controls the dimming of the lighting device 50 by using, for example, the control address included in the control signal corresponding to RDM.

Next, the correction process of the irradiation direction of the lighting device 10 when the elevating position of the baton B set at the time of preparation is changed will be described.

Here, the elevating position of the baton B may be changed, for example, in a television studio when the baton B is reflected in the range of the camera at the elevating position at the time of preparation. When the elevating position of the baton B is changed, the position of the lighting device 10 also changes, so that it is necessary to readjust the irradiation direction of the lighting device 10, which may cause the user to feel annoyed.

Therefore, the control device 1 according to the embodiment automatically corrects the irradiation direction of the lighting device 10 suspended from the baton B when the elevating position of the baton B is changed. This point will be described with reference to FIG. 1B.

FIG. 1B is a diagram showing a correction process by the control device 1. As shown in the left figure of FIG. 1B, it is assumed that the baton B is set with a predetermined height H1 from the ground as an elevating position at the time of preparation. Further, the lighting device 10 irradiates the point P with the direction of the angle α as the irradiation direction with respect to the vertical direction.

In such a case, as shown in the right figure of FIG. 1B, when the elevating position is changed to the height H2, the irradiation direction of the lighting device 10 is corrected based on the elevating position before and after the change. In the example shown in FIG. 1B, the angle β is corrected in order to irradiate the point P even after the elevating position is changed. The correction from the angle α to the angle β is performed based on the trigonometric function, and this point will be described with reference to FIG.

As described above, according to the control device 1 according to the embodiment, even when the elevating position of the baton B is changed, the irradiation direction of the lighting device 10 can be automatically corrected, which is troublesome for the user. Can be reduced.

<Configuration example of control device>
Next, a configuration example of the control device 1 according to the embodiment will be described with reference to FIG. FIG. 2 is a functional block diagram showing the configuration of the control device 1 according to the embodiment.

As shown in FIG. 2, the control device 1 includes a communication unit 2, a control unit 3, a storage unit 4, and a display unit 5.

The communication unit 2 is realized by, for example, a predetermined communication circuit or the like. For example, the communication unit 2 relays communication with the node 20 and the elevating device 30 via a network such as Ethernet or LAN.

The control unit 3 has an internal memory for storing a program that defines various processing procedures and required data, and executes various processing by these. In the embodiment, the control unit 3 includes an acquisition unit 31, a correction unit 32, a dimming control unit 33, an elevating control unit 34, and a display control unit 35.

The storage unit 4 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk or an optical disk. As shown in FIG. 2, the device information 41 is stored in the storage unit 4.

The device information 41 is information about the lighting device 10, and is information transmitted from the lighting device 10. FIG. 3 is a diagram showing an example of the device information 41. As shown in FIG. 3, the device information 41 includes information of "ID number", "UID", "DMX address", "irradiation direction", "size" and "height".

The "ID number" is identification information for identifying the lighting device 10. The "UID" is information represented by a 12-digit hexadecimal number previously assigned to the lighting device 10. The "DMX address" is a control address for the control device 1 to control each lighting device 10. The "size" is size information indicating the size of the lighting device 10, and is, for example, length information of the length, width, and height of the product. The "height" is, for example, a height position from the ground.

Next, each function of the control unit 3 (acquisition unit 31, correction unit 32, dimming control unit 33, elevating control unit 34, and display control unit 35) will be specifically described.

The acquisition unit 31 acquires various types of information. For example, the acquisition unit 31 acquires the elevating position information indicating the elevating position of the baton B. The elevating position information is, for example, information on the height from the ground to the baton B.

Further, when a plurality of lighting devices 10 are arranged on the baton B, the acquisition unit 31 acquires size information indicating the size of each lighting device 10. Further, the acquisition unit 31 acquires irradiation information regarding the current irradiation direction and the current irradiation range of the lighting device 10.

When the elevating position of the baton B is changed, the correction unit 32 corrects the irradiation direction of the lighting device 10 based on the elevating position before and after the change. Here, the correction process of the irradiation direction by the correction unit 32 will be described with reference to FIG.

FIG. 4 is a diagram showing a correction process of the correction unit 32. As shown in FIG. 4, it is assumed that the elevating position of the baton B is changed from the height H1 to the height H2. In such a case, the correction unit 32 corrects the irradiation direction of the lighting device 10 based on the elevating position (height H1) before the change and the elevating position (height H2) after the change.

Specifically, the correction unit 32 uses a trigonometric function to calculate the angle β indicating the irradiation direction after the change. First, the correction unit 32 calculates the road surface distance L1 from the lighting device 10 to the point P based on the height H1 which is the elevating position before the change and the angle α which is the irradiation direction.

Then, the correction unit 32 calculates the angle β using the road surface distance L1. Specifically, as shown in the right figure of FIG. 4, the correction unit 32 sets the road surface distance L2 from the changed lighting device 10 to the point P as the above-mentioned road surface distance L1, and is the height which is the raised / lowered position after the change. The corrected angle β is calculated based on H2. As a result, the irradiation direction can be corrected with high accuracy.

In FIG. 4, the angle β was calculated using the heights H1 and H2 from the baton B to the ground. For example, instead of the heights H1 and H2 from the baton B to the ground, the lighting device 10 to the ground. The angle β may be calculated using the height of.

For example, the height obtained by subtracting the size (vertical direction) of the lighting device 10 from the heights H1 and H2 can be used. More specifically, the correction unit 32 corrects the irradiation direction of each of the plurality of lighting devices 10 based on the size information indicating the size of each of the plurality of lighting devices 10. Thereby, when the sizes of the lighting devices 10 suspended from the baton B are different, the correction can be performed according to the size of the lighting device 10.

Further, the correction unit 32 may consider, for example, the suspension distance from the baton B to the lighting device 10. Specifically, the correction unit 32 can use a height obtained by subtracting the suspension distance from the heights H1 and H2 (further, the size of the lighting device 10 may be subtracted). As a result, when the hanging distance from the baton B is different, the correction can be performed according to the hanging distance.

Further, the correction unit 32 may correct the dimming state such as the irradiation range and the illuminance in addition to the correction of the irradiation direction. Specifically, the correction unit 32 corrects the dimming state of the lighting device 10 based on the corrected irradiation direction. For example, the correction unit 32 corrects so that the irradiation range and the illuminance at the point P do not change before and after the change.

The dimming control unit 33 controls the dimming of the lighting device 10. Specifically, the dimming control unit 33 transmits control information including information such as the illuminance of the lighting device 10, color, irradiation direction, and irradiation range to the lighting device 10. The dimming control unit 33 transmits control information including information on the irradiation direction and irradiation range corrected by the correction unit 32 when the elevating position of the baton B is changed.

The elevating control unit 34 controls the elevating of the baton B by transmitting elevating control information based on the elevating command by the user to the elevating device 30. For example, the elevating position for each scene is stored in the storage unit 4, and the elevating control unit 34 indicates the elevating position of the scene when the button corresponding to each scene arranged in the display unit 5 is pressed. Elevation control information is transmitted to the elevating device 30.

Alternatively, the elevating control unit 34 transmits the elevating control information corresponding to the ascending or descending to the elevating device 30 when either the ascending button or the descending button displayed on the display unit 5 is pressed.

The display control unit 35 displays various information on the display unit 5. Here, the information displayed on the display unit 5 will be described with reference to FIG.

FIG. 5 is a diagram showing a screen example of the display unit 5. As shown in FIG. 5, the layout screen 500 displayed on the display unit 5 displays the baton display 510, the illumination display 520, the baton height 530, and the illumination height 540.

The baton height 530 is the elevating position information indicating the elevating position of the baton B. The illumination height 540 indicates the height from the illumination device 10 to the ground. The lighting height 540 is calculated based on the size information and the hanging distance information of the lighting device 10. That is, the display control unit 35 displays the height information indicating the height position of each of the plurality of lighting devices 10 on the display unit 5 based on the suspension distance information and the size information.
