The present invention relates to a lighting system.

Various lighting devices are installed in homes, stores, exhibition halls, etc. Examples of lighting devices include spotlights, ceiling lights, downlights, pendant lights, bracket lights, etc. Some of these lighting devices can be remotely controlled to turn on/off, dim (adjust brightness), and adjust color (adjust color temperature). When controlling a lighting device remotely, a control signal is sent from a remote control terminal to the lighting device using a short-range wireless communication method (see Patent Document 1).

Among spotlights, there are motor-driven variable lighting devices (moving spotlights). With these variable lighting devices, the driving state of the motor can be remotely controlled to control the direction of illumination by panning (rotating in a horizontal plane) or tilting (swinging in a vertical plane) the direction of illumination, as well as the light distribution angle.

JP 2002-289369 A

However, with conventional lighting systems, the operator had to manually adjust the direction of illumination and the angle of light distribution each time, and it was not possible to perform this through timer control using a timer function.

The present invention aims to provide a lighting system that can control the direction of illumination by timer control using a timer function.

The lighting system according to the present invention is characterized in that it is equipped with a variable lighting device capable of variably controlling the direction of illumination light and a remote control terminal capable of outputting a control signal to the variable lighting device, and is configured to operate the variable lighting device so that the illumination direction is set to a preset direction when a preset timer execution time is reached.

The lighting system according to the present invention may be configured such that a plurality of the variable lighting devices are provided, each of the variable lighting devices is capable of bidirectional wireless communication with the other variable lighting devices, and a mesh network can be constructed using the plurality of variable lighting devices.

Furthermore, in the lighting system according to the present invention, the remote control terminal may be configured to be able to set the timer execution time, and may be configured to output the control signal when the timer execution time arrives.

Furthermore, the lighting system according to the present invention may be configured so that the control signal output from the remote control terminal is transmitted to all variable lighting devices constituting the mesh network via the variable control device that received the control signal and the mesh network.

According to the present invention, the direction of irradiation can be controlled by timer control using a timer function.

The lighting system according to an embodiment of the present invention will be described in detail below with reference to the attached drawings.

[Explanation of Overall Configuration of Lighting System]
First, the overall configuration of the lighting system according to this embodiment will be described with reference to Fig. 1. As shown in Fig. 1, the lighting system LS according to this embodiment is composed of a plurality of (e.g., 12) variable lighting devices (moving spotlights) 10 and a tablet 90 which is a remote control terminal.

Each variable lighting device 10 is a motor-driven moving spotlight that can be controlled to turn on and off, adjust brightness and color, and control the direction of illumination and the angle of light distribution.

In this specification, "dimming" refers to adjusting the brightness of the illumination light of the variable lighting device 10 stepwise or steplessly (continuously), "color adjustment" refers to adjusting the color (color temperature) of the illumination light of the variable lighting device 10 stepwise or steplessly (continuously). Furthermore, "control of the illumination direction" refers to variable control of the illumination direction of the illumination light of the variable lighting device 10 stepwise or steplessly (continuously) by panning (Pan, rotation in a horizontal plane) or tilting (Tilt, swinging in a vertical plane). Furthermore, "light distribution angle" refers to the spread angle of the illumination light of the variable lighting device 10, i.e., the illumination range of the illumination light, and "control of the light distribution angle" refers to variable control of the light distribution angle stepwise or steplessly (continuously).

Each variable lighting device 10 has a built-in communication module (described below) and can transmit and receive between adjacent devices using a short-range wireless communication method, such as Bluetooth (Bluetooth 5.0: registered trademark), and is connected by a connection in which one adjacent device acts as a master and the other as a slave. This allows two-way wireless communication between each variable lighting device 10, and a mesh network MN is constructed by these 12 variable lighting devices 10. In FIG. 1, the "connection" is indicated by a curved double-headed arrow.

The 12 variable lighting devices 10 each have a device ID (identification) No. 1 to No. 12 for identifying each of them.
1, the variable lighting devices 10 No. 1 to No. 12 are divided into a first group and a second group. The variable lighting devices 10 No. 1 to No. 6 belonging to the first group have a group ID of G1, and the variable lighting devices 10 No. 7 to No. 12 belonging to the second group have a group ID of G2. In other words, the group ID of the group to which each variable lighting device 10 belongs is stored in a memory provided in each variable lighting device 10.

The tablet 90 has a communication function and is configured to be able to transmit and receive between one of the multiple variable lighting devices 10 (e.g., the one closest in distance or the one with the highest communication strength) by a short-distance wireless communication method, such as Bluetooth (Bluetooth 5.0: registered trademark). In the example of FIG. 1, the tablet 90 and No. 1 variable lighting device 10 are connected by a connection, and two-way wireless communication is possible between the tablet 90 and No. 1 variable lighting device 10. Note that the tablet 90 is not always connected to the No. 1 variable lighting device 10, and may be connected to a variable lighting device 10 other than the No. 1 variable lighting device 10 depending on the movement of the tablet 90, etc.

The tablet 90 outputs various control signals to control the lighting on/off, dimming and color adjustment, as well as the direction of illumination (panning and tilting) and the light distribution angle. The tablet 90 also has a timer function.

In this embodiment, as described above, Bluetooth (Bluetooth 5.0: registered trademark) is used as a communication method for two-way wireless communication between the tablet 90 and the variable lighting device 10 and between each of the variable lighting devices 10 constituting the mesh network MN. This makes the communication highly reliable and enables the transmission and reception of many types of signals. In other words, when one of the 40 channels in the 2.4 GHz band that is being used becomes disconnected due to radio interference, Bluetooth (Bluetooth 5.0: registered trademark) can select a channel that is not subject to radio interference from among the other channels, and hop the channel to be used to a stable channel that is not subject to radio interference without interrupting communication, resulting in high communication reliability. In addition, Bluetooth (Bluetooth 5.0: registered trademark) can set many signal generators, so it can transmit and receive many types of signals, and as a result, as described later, it is possible to execute not only "on/off, dimming and color adjustment control" but also "illumination direction (pan and tilt) and light distribution angle control" by timer control using a timer function.

Details of the mechanical and control configuration of the variable lighting device 10, as well as the operation screen of the tablet 90 and the method of setting each signal, will be described later.

[Description of real-time control operation]
The outline of the real-time control operation will be described first as follows. That is, in the real-time control operation, the operator operates the tablet 90 to output a control signal while visually checking the light emission state of the light source of the variable lighting device 10, such as on/off, dimming, and color adjustment, and the irradiation direction (pan and tilt) and light distribution angle of the light (illumination light) emitted from the variable lighting device 10. In this way, the operator outputs a control signal while visually checking each state, and performs "control of on/off, dimming, and color adjustment" and "control of irradiation direction (pan and tilt) and light distribution angle". Then, when the appropriate "on/off, dimming, and color adjustment state" and "irradiation direction (pan and tilt) and light distribution angle state" are achieved, the control by the tablet 90 is terminated.
The real-time control operations will be explained below in order.

First, if the operator wishes to specify and control, for example, variable lighting devices 10 No. 1 to No. 6 that belong to the first group among the multiple variable lighting devices 10, the operator sets G1 as the group ID in the tablet 90.

Then, the operator operates the tablet 90, for example, by outputting each control signal described later from the tablet 90 to control the on/off, dimming and color adjustment of the light sources of the variable lighting devices 10 No. 1 to No. 6, and the irradiation direction (pan and tilt) and light distribution angle of the light emitted from the variable lighting devices 10 No. 1 to No. 6. This makes it possible to simultaneously and interlockingly control the on/off, dimming and color adjustment states, irradiation direction (pan and tilt) and light distribution angle states of the variable lighting devices 10 No. 1 to No. 6 belonging to the first group.

In this example, since G1 indicating the group ID of the first group is set in the tablet 90, group ID information of group ID=G1 is linked to each control signal output from the tablet 90. In other words, each control signal is output from the tablet 90 with group ID information of group ID=G1 added.
The control states when each control signal is output from the tablet 90 are as follows.

When the tablet 90 outputs an on/off control signal C4 having a lighting instruction as information, the on/off control signal C4 is received by the No. 1 variable lighting device 10. Furthermore, the on/off control signal C4 received by the No. 1 variable lighting device 10 is sequentially transmitted from the No. 1 variable lighting device 10 to each of the No. 2 to No. 12 variable lighting devices 10 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the on/off control signal C4 to which the group ID information of group ID=G1 is added, they take in the on/off control signal C4 and perform a control operation to turn on the light source of the variable lighting device 10 in accordance with the taken in on/off control signal C4.
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not receive the on/off control signal C4 and do not perform a lighting operation because the group ID information of group ID=G2 is not added to the on/off control signal C4.

When the on/off control signal C4 having a turn-off instruction as information is output from the tablet 90, the on/off control signal C4 is transmitted and received in the same manner as described above, and the light sources in the variable lighting devices 10 No. 1 to No. 6 are controlled to be turned off.
The dimming control and color adjustment control described below are based on the premise that the variable lighting devices 10 No. 1 to No. 6 to be controlled are turned on.

When the dimming control signal C5 having dimming level information is output from the tablet 90, this dimming control signal C5 is received by the No. 1 variable lighting device 10. Furthermore, the dimming control signal C5 received by the No. 1 variable lighting device 10 is transmitted in sequence from the No. 1 variable lighting device 10 to each of the No. 2 to No. 12 variable lighting devices 10 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the dimming control signal C5 to which the group ID information of group ID=G1 is added, they take in the dimming control signal C5 and perform a control operation of controlling the dimming degree of the light source of the variable lighting device 10 in accordance with the taken in dimming control signal C5.
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the dimming control signal C5 even if they receive the dimming control signal C5, because the group ID information of group ID=G2 is not added to the dimming control signal C5.

When the color adjustment control signal C6 having the color adjustment degree information is output from the tablet 90, this color adjustment control signal C6 is received by the No. 1 variable lighting device 10. Furthermore, the color adjustment control signal C6 received by the No. 1 variable lighting device 10 is transmitted in sequence from the No. 1 variable lighting device 10 to each of the No. 2 to No. 12 variable lighting devices 10 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the color adjustment control signal C6 to which the group ID information of group ID=G1 is added, they take in the color adjustment control signal C6 and perform a control operation of controlling the color adjustment degree of the light source of the variable lighting device 10 in accordance with the taken in color adjustment control signal C6.
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the color adjustment control signal C6 even if they receive the color adjustment control signal C6, because the group ID information of group ID=G2 is not added to the color adjustment control signal C6, and therefore do not control the color adjustment degree.

When the turning control signal C1 having the turning angle information is output from the tablet 90, this turning control signal C1 is received by the variable lighting device 10 No. 1. Furthermore, the turning control signal C1 received by the variable lighting device 10 No. 1 is sequentially transmitted from the variable lighting device 10 No. 1 to each of the variable lighting devices 10 No. 2 to No. 12 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the turning control signal C1 to which the group ID information of group ID=G1 is added, the variable lighting devices 10 take in the turning control signal C1 and perform a control operation of controlling the turning angle of the variable lighting devices 10 in accordance with the taken in turning control signal C1.
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the turning control signal C1 even if they receive the turning control signal C1, because the group ID information of group ID=G2 is not added to the turning control signal C1, and therefore do not control the turning angle.

When the oscillation control signal C2 having the oscillation angle information is output from the tablet 90, this oscillation control signal C2 is received by the No. 1 variable lighting device 10. Furthermore, the oscillation control signal C2 received by the No. 1 variable lighting device 10 is transmitted in sequence from the No. 1 variable lighting device 10 to each of the No. 2 to No. 12 variable lighting devices 10 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the swing control signal C2 to which the group ID information of group ID=G1 is added, they take in the swing control signal C2 and perform a control operation of controlling the swing angle of the variable lighting device 10 in accordance with the taken in swing control signal C2.
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the swing control signal C2 and do not control the swing angle, even if they receive the swing control signal C2, because the group ID information of group ID=G2 is not added to the swing control signal C2.

The rotation angle and oscillation angle of the variable lighting device 10 are controlled by the rotation control signal C1 and the oscillation control signal C2 to determine the direction of illumination, so both signals C1 and C2 serve as illumination direction control signals.

When the light distribution angle control signal C3 having the light distribution angle as information is output from the tablet 90, this light distribution angle control signal C3 is received by the No. 1 variable lighting device 10. Furthermore, the light distribution angle control signal C3 received by the No. 1 variable lighting device 10 is transmitted in sequence from the No. 1 variable lighting device 10 to each of the No. 2 to No. 12 variable lighting devices 10 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the light distribution angle control signal C3 to which the group ID information of group ID=G1 is added, they take in this light distribution angle control signal C3 and perform a control operation of controlling the light distribution angle of the emission light emitted from the variable lighting devices 10 in accordance with the taken in light distribution angle control signal C3.
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the light distribution angle control signal C3 and do not control the light distribution angle, even if they receive the light distribution angle control signal C3, because the group ID information of group ID=G2 is not added to the light distribution angle control signal C3.

As described above, when G1 is set as the group ID in the tablet 90 to control the on/off, dimming and color adjustment, as well as the irradiation direction (rotation (pan) and tilt) and light distribution angle, each control signal C1 to C6 is linked (added) to group ID information of group ID = G1 and output. Therefore, control to make the on/off, dimming and color adjustment states of the variable lighting devices 10 No. 1 to No. 6 of the first group having G1 as the group ID the same, and control to make the irradiation direction (pan and tilt) and light distribution angle state the same can be simultaneously and interlocked. As a result, the on/off, dimming and color adjustment states of the variable lighting devices 10 No. 1 to No. 6 can be easily set to the same state in interlocking, and the irradiation direction (pan and tilt) and light distribution angle states of the variable lighting devices 10 No. 1 to No. 6 can be easily set to the same state in interlocking.

When G2 is set as the group ID in the tablet 90 to control the on/off, dimming and color adjustment, as well as the irradiation direction (rotation (pan) and tilt) and light distribution angle, each control signal C1 to C6 is linked (added) to group ID information of group ID = G2 and output. Therefore, by outputting each control signal C1 to C6 in the same manner as the control in the first group, it is possible to simultaneously and interlockingly control the on/off, dimming and color adjustment states of the variable lighting devices 10 No. 7 to No. 12 of the second group having G2 as the group ID to be in the same state, and control the irradiation direction (pan and tilt) and light distribution angle states to be in the same state. As a result, it is possible to easily set the on/off, dimming and color adjustment states of the variable lighting devices 10 No. 7 to No. 12 to be in the same state in an interlocking manner, and it is also possible to simultaneously and interlockly control the on/off, dimming and color adjustment states of the variable lighting devices 10 No. 7 to No. 12 of the second group. The illumination direction (pan and tilt) and light distribution angle of the 12 variable lighting devices 10 can be linked and easily set to the same state.

In the above example, two groups, group 1 and group 2, were set, but the number of groups that can be set can be greater. One to multiple device IDs can be set for each group (one group).

Therefore, for example, when one variable lighting device 10 (device ID) is set for one group, that is, when the device IDs of 12 variable lighting devices are set in a one-to-one relationship for the first to twelfth groups, it is possible to control the on/off, dimming, and color adjustment of each variable lighting device 10 (one group), as well as the irradiation direction (rotation (pan) and oscillation (tilt)) and light distribution angle. As a result, even if a mesh network MN is constructed as shown in FIG. 1, it is possible to individually control the on/off, dimming, and color adjustment of each variable lighting device 10, as well as the irradiation direction (rotation (pan) and oscillation (tilt)) and light distribution angle.

[Description of control operations by registration and playback]
In this control operation by registration and reproduction, G1 indicating the group ID of the first group is also set in the tablet 90. For this reason, each of the control signals C1 to C6, each of the registration command signals α, γ, and each of the reproduction command signals β, δ output from the tablet 90 is output with the group ID information, group ID=G1, linked (added) thereto.

In the control operation by registration and replay, the operator first outputs the on/off control signal C4, the dimming control signal C5, and the color adjustment control signal C6 from the tablet 90 by the above-mentioned real-time control operation to set the on/off, dimming, and color adjustment states (these states are called "scenes") of the variable lighting devices 10 No. 1 to No. 6 belonging to the first group to a predetermined scene. When the operator operates the tablet 90 to output a scene registration command signal γ1 in this state, the scene registration command signal γ1 is received by the variable lighting device 10 No. 1 and is further transmitted to the variable lighting devices 10 No. 2 to No. 12 via each connection of the mesh network MN. In this example, since the group ID information of group ID = G1 is linked (added) to the scene registration command signal γ1, the scene registration command signal γ1 is sent to the variable lighting devices 10 No. 1 to No. 12 among the variable lighting devices 10 No. 1 to No. 12. In the variable lighting device 10 of 6, the scene registration command signal γ1 is received and the aforementioned specific scene is registered as scene registration 1.

In addition, the operator outputs the rotation control signal C1, the oscillation control signal C2, and the light distribution angle control signal C3 from the tablet 90 by the above-mentioned real-time control operation to set the rotation angle, oscillation angle, and light distribution angle (these states are called "angles") of the variable lighting devices 10 No. 1 to No. 6 belonging to the first group to a predetermined angle. When the operator operates the tablet 90 to output the angle registration command signal αA in this state, the angle registration command signal αA is received by the variable lighting device 10 No. 1 and is further transmitted to the variable lighting devices 10 No. 2 to No. 12 via each connection of the mesh network MN. In this example, since the group ID information of group ID = G1 is linked (added) to the angle registration command signal αA, the variable lighting devices 10 No. 1 to No. 6 among the variable lighting devices 10 No. 1 to No. 12 are connected (added) to the angle registration command signal αA. In the variable lighting device 10 of 6, the angle registration command signal αA is received and the aforementioned specific angle is registered as angle registration A.

After that, when real-time control operations are performed, the scenes of variable lighting devices 10 No. 1 to No. 6 deviate from scene registration 1, and the angles of variable lighting devices 10 No. 1 to No. 6 deviate from angle registration A.

When the scenes of the variable lighting devices 10 No. 1 to No. 6 are shifted from the registered scene 1, if the operator operates the tablet 90 to output a registered scene playback command signal δ1 instructing to play back the registered scene 1, this registered scene playback command signal δ1 is received by the variable lighting device 10 No. 1. Furthermore, the registered scene playback command signal δ1 received by the variable lighting device 10 No. 1 is transmitted in sequence from the variable lighting device 10 No. 1 to each of the variable lighting devices 10 No. 2 to No. 12 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the registered scene playback command signal δ1 to which the group ID information of group ID=G1 is added, they take in the registered scene playback command signal δ1. The variable lighting devices 10 No. 1 to No. 6 that have taken in the registered scene playback command signal δ1 each control the lighting on/off, dimming, and color adjustment so that the scene of the device matches the scene registered as scene registration 1 (so as to reproduce/restore the scene).
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the registered scene playback command signal δ1 and do not control turning on/off, dimming, or color adjustment, even if they receive the registered scene playback command signal δ1, because the group ID information of group ID=G2 is not added to the registered scene playback command signal δ1.

When the angles of the variable lighting devices 10 No. 1 to No. 6 deviate from the registered angle A, and the operator operates the tablet 90 to output a registered angle reproduction command signal βA instructing to reproduce the registered angle A, this registered angle reproduction command signal βA is received by the variable lighting device 10 No. 1. Furthermore, the registered angle reproduction command signal βA received by the variable lighting device 10 No. 1 is sequentially transmitted from the variable lighting device 10 No. 1 to each of the variable lighting devices 10 No. 2 to No. 12 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the registered angle reproduction command signal βA to which the group ID information of group ID=G1 is added, the variable lighting devices 10 No. 1 to No. 6 that have received the registered angle reproduction command signal βA control the rotation angle, the oscillating angle, and the light distribution angle so that the angle of the device matches the angle registered as angle registration A (so as to reproduce/restore the angle).
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the registered angle reproduction command signal βA even if they receive the registered angle reproduction command signal βA, because the group ID information of group ID=G2 is not added to the registered angle reproduction command signal βA, and therefore do not control the rotation angle, the oscillation angle, and the light distribution angle.

If G2 is set as the group ID on the tablet 90, control operations can be performed by registering and regenerating the variable lighting devices 10 No. 7 to No. 12 in the second group, which have G2 as the group ID, in the same manner as the control in the first group.

For example, after setting the scenes of the variable lighting devices 10 No. 7 to No. 12 to a predetermined scene, when the operator operates the tablet 90 to output a scene registration command signal γ2, the group ID information of group ID=G2 is linked (added) to the scene registration command signal γ2, so that the predetermined scene is registered as scene registration 2 in each of the variable lighting devices 10 No. 7 to No. 12.
In addition, after setting the angles of the variable lighting devices 10 No. 7 to No. 12 to predetermined angles, when the operator operates the tablet 90 to output an angle registration command signal αB, the group ID information of group ID=G2 is linked (added) to the angle registration command signal αB, so that the predetermined angle is registered as angle registration B in each of the variable lighting devices 10 No. 7 to No. 12.

Thereafter, when the scene of each of the variable lighting devices 10 No. 7 to No. 12 deviates from the scene registration 2, the operator operates the tablet 90 to output a registered scene playback command signal δ2 instructing to play back the scene registration 2, and each of the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) receives and captures the registered scene playback command signal δ2 to which the group ID information of group ID=G2 is added, and controls turning on/off, dimming, and color adjustment so that the scene of the device matches the scene registered as the scene registration 2 (so as to reproduce/restore the scene).
In addition, when the angle of the variable lighting devices 10 No. 7 to No. 12 deviates from the registered angle B, if the operator operates the tablet 90 to output a registered angle reproduction command signal βB instructing to reproduce the registered angle B, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) receive and capture the registered angle reproduction command signal βB to which the group ID information of group ID=G2 is added, and control the rotation angle, the oscillation angle, and the light distribution angle so that the angle of the device matches the angle registered as the registered angle B (so as to reproduce/restore the angle).

In the timer setting control operation, a timer function incorporated in the tablet 90 can be used to set a time (timer execution time T) at which the registered scene playback command signals δ1, δ2 and the registered angle playback command signals βA, βB are automatically output from the tablet 90. For example, when the timer execution time T1 arrives, the tablet 90 can be set to automatically output the registered scene playback command signal δ1 and the registered angle playback command signal βA to which the group ID information of group ID=G1 is added in order to control the scenes and angles of the variable lighting devices 10 of No. 1 to No. 6. Also, when the timer execution time T2 arrives, the tablet 90 can be set to automatically output the registered scene playback command signal δ2 and the registered angle playback command signal βB to which the group ID information of group ID=G2 is added in order to control the scenes and angles of the variable lighting devices 10 of No. 7 to No. 12.

To perform this timer setting control operation, before setting the timer execution time T, for example, scene registration 1 and angle registration A are registered in the variable lighting devices 10 No. 1 to No. 6 belonging to the first group, and scene registration 2 and angle registration B are registered in the variable lighting devices 10 No. 7 to No. 12 belonging to the second group. Also, for example, the timer execution time T1 is set by linking the scene registration 1 and the angle registration A, and the timer execution time T2 is set by linking the scene registration 2 and the angle registration B.
As a result, the timer execution time T1, scene registration 1, angle registration A, and group ID information of group ID=G1 are linked and set, and the timer execution time T2, scene registration 2, angle registration B, and group ID information of group ID=G2 are linked and set.

The following control operations can also be performed by using a timer function built into the tablet 90.
For example, the on/off control signal C4, the dimming control signal C5, and the color adjustment control signal C6 for controlling to a "different scene state" from the scenes shown in the above-mentioned scene registrations 1 and 2, and the rotation control signal C1, the swing control signal C2, and the light distribution angle control signal C3 for controlling to a "different angle state" from the above-mentioned angle registrations A and B are preset in the tablet 90. Then, for example, when the timer execution time T3 arrives, the previously set on/off control signal C4, the dimming control signal C5, and the color adjustment control signal C6, and the previously set rotation control signal C1, the swing control signal C2, and the light distribution angle control signal C3 can be output from the tablet 90 to set the scene and angle of the variable lighting device 10 to the above-mentioned "different scene state" and "different angle state."

[Description of the combined operation of the control operation by registration/playback and the timer setting control operation]
Next, a procedure for performing a combination of a control operation based on registration and reproduction and a timer setting control operation in the lighting system LS shown in FIG. 1 will be described.

First, the operator sets G1 as the group ID on the tablet 90 to identify the variable lighting devices 10 to be controlled among the multiple variable lighting devices 10 (No. 1 to No. 12), for example, variable lighting devices 10 No. 1 to No. 6.

In this example, G1 indicating the group ID of the first group is set in the tablet 90, and therefore each control signal C1 to C6, each registered command signal αA, γ1, and each playback command signal βA, δ1 output from the tablet 90 are linked with group ID information of group ID=G1. In other words, each control signal C1 to C6, each registered command signal αA, γ1, and each playback command signal βA, δ1 are output from the tablet 90 with group ID information of group ID=G1 attached.

The operator outputs the on/off control signal C4, the dimming control signal C5 and the color adjustment control signal C6 from the tablet 90 through the above-mentioned real-time control operation, and sets the "scenes" that are the on/off, dimming and color adjustment states of the variable lighting devices 10 No. 1 to No. 6 belonging to the first group to a desired predetermined scene.
In addition, the operator outputs the rotation control signal C1, the oscillation control signal C2, and the light distribution angle control signal C3 from the tablet 90 by the above-mentioned real-time control operation, and sets the "angles" that are the rotation angle, the oscillation angle, and the light distribution angle of the variable lighting devices 10 No. 1 to No. 6 belonging to the first group to the desired predetermined angles.

After setting the scenes of the variable lighting devices 10 No. 1 to No. 6 belonging to the first group to the desired predetermined scene, when the operator operates the tablet 90 to output a scene registration command signal γ1, this scene registration command signal γ1 is received by the variable lighting device 10 No. 1. Furthermore, the scene registration command signal γ1 received by the variable lighting device 10 No. 1 is transmitted in sequence from the variable lighting device 10 No. 1 to each of the variable lighting devices 10 No. 2 to No. 12 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the scene registration command signal γ1 to which the group ID information of group ID=G1 is added, the variable lighting devices 10 respectively capture the scene registration command signal γ1 and register the predetermined scene as scene registration 1.
The variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not receive the dimming control signal C5 and do not register the scene even if they receive the scene registration command signal γ1, because the group ID information of group ID=G2 is not added to the scene registration command signal γ1.

After setting the angles of the variable lighting devices 10 No. 1 to No. 6 belonging to the first group to the desired angles, when the operator operates the tablet 90 to output an angle registration command signal αA, this angle registration command signal αA is received by the variable lighting device 10 No. 1. Furthermore, the angle registration command signal αA received by the variable lighting device 10 No. 1 is transmitted in sequence from the variable lighting device 10 No. 1 to each of the variable lighting devices 10 No. 2 to No. 12 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the angle registration command signal αA to which the group ID information of group ID=G1 is added, the variable lighting devices 10 respectively take in the angle registration command signal αA and register the above-mentioned predetermined angle of their own as the angle registration A.
The variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not receive the dimming control signal C5 and do not register the angle even if they receive the angle registration command signal αA, because the group ID information of group ID=G2 is not added to the angle registration command signal αA.

After registering scene registration 1 and angle registration A in variable lighting devices 10 No. 1 to No. 6 as described above, the operator sets a timer execution time T1 for playing scene registration 1 and angle registration A in the tablet 90. This timer execution time T1 is set in the tablet 90 in a state where scene registration 1, angle registration A, and group ID information of group ID = G1 are linked (added).

After that, a real-time control operation is performed, and the scenes of the variable lighting devices 10 No. 1 to No. 6 deviate from scene registration 1, and the angles of the variable lighting devices 10 No. 1 to No. 6 deviate from angle registration A.

When the timer execution time T1 arrives after being set, the timer function automatically outputs a registered scene playback command signal δ1, which instructs the tablet 90 to play back scene registration 1, and a registered angle playback command signal βA, which instructs the tablet 90 to play back angle registration A, from the tablet 90, even if the operator does not operate the tablet 90.

When the timer execution time T1 has elapsed, the registered scene playback command signal δ1 output from the tablet 90 is received by the No. 1 variable lighting device 10. Furthermore, the registered scene playback command signal δ1 received by the No. 1 variable lighting device 10 is transmitted in sequence from the No. 1 variable lighting device 10 to each of the No. 2 to No. 12 variable lighting devices 10 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the registered scene playback command signal δ1 to which the group ID information of group ID=G1 is added, they take in the registered scene playback command signal δ1. The variable lighting devices 10 No. 1 to No. 6 that have taken in the registered scene playback command signal δ1 each control the lighting on/off, dimming, and color adjustment so that the scene of the device matches the scene registered as scene registration 1 (so as to reproduce/restore the scene).
Therefore, when the timer execution time T1 arrives, the variable lighting devices 10 No. 1 to No. 6 are controlled to turn on/off, dim, and adjust the color, and the scene of the device automatically becomes the scene indicated in scene registration 1.
On the other hand, the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) do not take in the registered scene playback command signal δ1 and do not control turning on/off, dimming, or color adjustment, even if they receive the registered scene playback command signal δ1, because the group ID information of group ID=G2 is not added to the registered scene playback command signal δ1.

When the timer execution time T1 has elapsed, the registered angle reproduction command signal βA output from the tablet 90 is received by the No. 1 variable lighting device 10. Furthermore, the registered angle reproduction command signal βA received by the No. 1 variable lighting device 10 is transmitted in sequence from the No. 1 variable lighting device 10 to each of the No. 2 to No. 12 variable lighting devices 10 via each connection of the mesh network MN.
When the variable lighting devices 10 No. 1 to No. 6 belonging to the first group (having G1 as the group ID) receive the registered angle reproduction command signal βA to which the group ID information of group ID=G1 is added, the variable lighting devices 10 No. 1 to No. 6 that have received the registered angle reproduction command signal βA control the rotation angle, the oscillation angle, and the light distribution angle so that the angle of the device matches the angle registered as angle registration A (so as to reproduce/restore the angle).
Therefore, when the timer execution time T1 arrives, the rotation angle, the oscillation angle, and the light distribution angle are controlled in the variable lighting devices 10 No. 1 to No. 6, and the angle of the device automatically becomes the angle indicated in the angle registration A.
On the other hand, even if the variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) receive the registered angle reproduction command signal βA, the group ID information of group ID=G2 is not added to this registered angle reproduction command signal βA, so that the variable lighting devices 10 do not address this registered angle reproduction command signal βA and do not control the rotation angle, the oscillating angle, and the light distribution angle.

As described above, when the timer execution time T1 arrives, the tablet 90 outputs the registered scene playback command signal δ1 and the registered angle playback command signal βA, and in the variable lighting devices 10 No. 1 to No. 6 belonging to the first group, the scene (on/off, dimming, color adjustment state) becomes the scene indicated in scene registration 1, and the angle (rotation angle, oscillating angle, light distribution angle state) becomes the angle indicated in angle registration A.

It should be noted that the variable lighting devices 10 No. 7 to No. 12 in the second group can also perform a combination of the control operation based on registration and playback and the timer setting control operation, similar to the variable lighting devices 10 No. 1 to No. 6.
In this case, first, G2 is set as the group ID for the tablet 90.
Next, the scenes of the variable lighting devices 10 No. 7 to No. 12 are set to a desired predetermined scene, and a scene registration command signal γ2 is output from the tablet 90 to register the predetermined scene as scene registration 2 in each of the variable lighting devices 10 No. 7 to No. 12.
In addition, the angles of the variable lighting devices 10 No. 7 to No. 12 are set to a desired predetermined angle, and an angle registration command signal αB is output from the tablet 90 to register the predetermined angle of each of the variable lighting devices 10 No. 7 to No. 12 as an angle registration B.

Furthermore, a timer execution time T2 for playing scene registration 2 and angle registration B is set on the tablet 90. This timer execution time T2 is set on the tablet 90 in a state where scene registration 2, angle registration B, and group ID information of group ID=G2 are linked (added).

When the timer execution time T2 has elapsed, the tablet 90 automatically outputs a registered scene playback command signal δ2 instructing the playback of scene registration 2, and a registered angle playback command signal βB instructing the playback of angle registration B.
The variable lighting devices 10 No. 7 to No. 12 belonging to the second group (having G2 as the group ID) receive and capture the registered scene playback command signal δ2 and the registered angle playback command signal βB to which the group ID information of group ID=G2 is added. As a result, the variable lighting devices 10 No. 7 to No. 12 control turning on/off, dimming, and color adjustment, so that the scene of the device automatically becomes the scene shown in scene registration 2, and control the rotation angle, oscillation angle, and light distribution angle, so that the angle of the device automatically becomes the angle shown in angle registration B.

In the above example, two groups, a first and a second, are set, and one timer execution time is set for each group, but the number of groups to be set and the number of timer execution times to be set for each group are not limited to this. Also, one to multiple device IDs can be set for each group.

For example, the device ID of the variable lighting device 10 No. 1 may be set as the first group, the device IDs of the variable lighting devices 10 No. 2 to No. 10 may be set as the second group, and the device IDs of the variable lighting devices 10 No. 11 to No. 12 may be set as the third group.
Then, the variable lighting device 10 No. 1 in the first group can be set so that its scene becomes the scene indicated in scene registration 1 and its angle becomes the angle indicated in angle registration A during timer execution time T1 and timer execution time T2 (i.e., during two timer execution times), the variable lighting device 10 No. 2 to No. 10 in the second group can be set so that its scene becomes the scene indicated in scene registration 2 and its angle becomes the angle indicated in angle registration B during timer execution time T3, and the variable lighting device 10 No. 11 to No. 12 in the third group can be set so that its scene becomes the scene indicated in scene registration 3 and its angle becomes the angle indicated in angle registration C during timer execution time T4.

[Explanation of the mechanical configuration of the variable lighting device]
Here, the mechanical configuration of the variable lighting device 10 constituting the mesh network MN will be briefly described with reference to FIGS.

The variable lighting device 10 is a lighting device that provides illumination by being attached to a lighting duct rail 1 arranged on a ceiling surface, for example.
This variable lighting device 10 has a base unit 20, a lamp 30 having a light source, an arm 40, a first drive unit 50 that rotates the lamp 30 and the arm 40 relative to the base unit 20, a second drive unit 60 that oscillates the lamp 30 relative to the base unit 20 and the arm 40, a rotation support unit 70 that supports the lamp 30 so that the lamp 30 can rotate relative to the arm 40, and a cable 80 (see Figures 3 and 4) in which the electric wires inside the fixture are covered with a protective tube.

The first driving unit 50 and the second driving unit 60 each have a motor, a reduction gear mechanism (worm gear), an output shaft, and a torque limiter structure.
The motor used is, for example, a brushed DC motor, which is inexpensive and small compared to a stepping motor or a servo motor. Because an inexpensive and small motor is used in this way, power consumption can be reduced, and the driving units 50 and 60 including the motor, and thus the variable lighting device 10, can be manufactured inexpensively and in a small size.

The torque limiter structure transmits torque between the motor and the output shaft when a torque equal to or less than a preset specified torque is applied, but when an excessive torque exceeding the specified torque is applied, slippage occurs and torque is not transmitted between the motor and the output shaft (torque transmission is cut off).

For this reason, for example, when the lamp 30 or the arm 40 is moving due to the motor being driven and the lamp 30 or the arm 40 collides with an obstacle or the like and becomes unable to move, excessive torque is applied to the torque limiter structure, causing slippage in the torque limiter structure and cutting off the torque transmission between the motor and the output shaft, thereby protecting the motor and the reduction gear mechanism.
When the motor is stopped and the lamp 30 or the arm 40 is moved manually, excessive torque is applied to the torque limiter structure, causing slippage in the torque limiter structure and cutting off torque transmission between the motor and the output shaft. This protects the motor and reduction gear mechanism, and allows the attitude of the lamp 30 (swivel angle, oscillating angle) to be adjusted manually.

In addition, a rotation angle detection sensor (described later) that detects the rotation angle of the lamp 30 and a swivel angle detection sensor (described later) that detects the swivel angle of the lamp 30 are provided. This allows the detection control system that detects the attitude (rotation angle, swivel angle) of the lamp 30 to be an independent control system from the drive control system that controls the drive of the motors of the first and second drive units 50, 60.

Furthermore, the rotation support part 70 supports the lamp 30 so that it can oscillate at the center of gravity of the lamp 30 among various positions along the axial direction of the approximately cylindrical lamp 30. This allows the lamp 30 to oscillate smoothly, and the motor of the second drive part 60 that oscillates the lamp 30 can be made smaller.

[Explanation of the mechanical configuration of each part of the variable lighting device]
Next, the mechanical configuration of each part of the variable lighting device 10 will be described.

[Configuration of the base part, etc.]
The base unit 20 is installed at an installation location such as a ceiling surface, and includes therein a communication module, various control units, a power supply unit, and a memory, as described below.

[Light fixture configuration, etc.]
As shown in FIG. 5, which is a VV cross section of FIG. 2, the lamp 30 is formed by connecting a front cylinder part 31 made of resin and a rear cylinder part 32 made of aluminum die casting in a coaxial state. Inside the front cylinder part 31, a lens 33 is attached so as to be movable along the axial direction. Inside the rear cylinder part 32, a heat dissipation fin 34 is formed on the rear side (right side in FIG. 5), and a light source mounting base 35 is formed on the front side (left side in FIG. 5). A light source (light emitting diode, LED) 36 is arranged on the surface of the light source mounting base 35 facing the lens 33. The light source 36 is equipped with two systems of LEDs with different color tones, for example, a light bulb color LED that generates light bulb color light and a white LED that generates white light. The lens 33 is configured to be movable along the axial direction of the lamp 30 by driving a lens movement motor described later. By moving the lens 33 in this way, the light distribution angle of the light generated from the light source 36 can be adjusted. The moving position of the lens 33 is detected by a lens position detection sensor described later.

As shown in FIG. 6, two shaft mounting holes 37 are formed on the outer peripheral surface of the rear cylinder portion 32. The shaft mounting holes 37 are formed at positions offset by 180° in the circumferential direction of the rear cylinder portion 32, and are formed at the center of gravity of the lamp 30 in the axial direction of the lamp 30 formed by connecting the front cylinder portion 31 and the rear cylinder portion 32.

[Arm configuration, etc.]
2 to 4, the arm 40 has a horizontal shaft portion 41 and two vertical shaft portions 42a, 42b hanging down from both ends of the horizontal shaft portion 41. The horizontal shaft portion 41 is connected to a first output shaft (described later) of a first drive portion 50. The tips (lower ends) of the vertical shaft portions 42a, 42b support the lamp 30 via a rotation support portion 70 so that the lamp 30 can be swiveled. The lamp 30 is disposed at a position sandwiched between the two vertical shaft portions 42a, 42b.

[Configuration of rotation support part, etc.]
As shown in FIG. 5, the pivot support portion 70 has a support shaft 71 and a support shaft 72. The support shaft 71 is inserted into one of the shaft mounting holes 37 formed in the peripheral surface of the rear cylinder portion 32. The support shaft 72 is inserted into the other shaft mounting hole 37 formed in the peripheral surface of the rear cylinder portion 32. The support shaft 71 is located at the lower end of the vertical shaft portion 42a of the arm 40, and the support shaft 72 is located at the lower end of the vertical shaft portion 42b of the arm 40. Therefore, the lamp 30 can rotate and oscillate with respect to the arm 40 around the shaft mounting holes 37, 37 into which the support shafts 71, 72 are inserted as the rotation center. In other words, the lamp 30 is supported by the arm 40 via the pivot support portion 70 in a pivotable manner, and is capable of oscillating.
In this way, since the support shafts 71, 72 of the pivot support part 70 are inserted into the shaft mounting holes 37, 37 formed at the center of gravity of the lamp 30, the lamp 30 can pivot around its center of gravity.
The support shaft 71 is disposed in a position coaxial with an output shaft (described later) of the second drive unit 60 .

[Configuration of the first driving unit, etc.]
2 to 4, the first driving unit 50 is attached to the base unit 20. That is, a housing 50a of the first driving unit 50 is attached to a housing 20a of the base unit 20. As shown in FIGS. 7 and 8, the first driving unit 50 has a rotation motor 51 which is a brushed DC motor arranged inside the housing 50a, a worm gear 52 which is a reduction gear mechanism, a first output shaft 53 which is formed with a male thread, a nut 54, and a wave washer 55.

The worm gear 52 is composed of a worm 52a connected to the rotating shaft of the rotation motor 51 and a worm wheel 52b that meshes with the worm 52a.

The first output shaft 53 is a pipe-shaped member having an insertion hole extending in the axial direction. When the variable lighting device 10 is attached to the lighting duct rail 1 as shown in FIG. 3 and FIG. 4, the first output shaft 53 is arranged so that its axial direction is along the vertical direction. This first output shaft 53 penetrates the housing 50a of the first drive unit 50 and is rotatably supported by a bearing 56 arranged in the housing 50a. A male thread 53a is formed on the outer circumferential surface of the first output shaft 53 located inside the housing 50a. In addition, the end of the first output shaft 53 located outside the housing 50a is located in the center of the longitudinal direction of the horizontal shaft portion 41 of the arm 40. A cable 80 (described later) is inserted through the insertion hole of the first output shaft 53.

The nut 54 is screwed onto the first output shaft 53 with a wave washer 55 interposed between the nut 54 and the worm wheel 52b. The inner and outer diameters of the nut 54 are approximately the same as the inner and outer diameters of the wave washer 55.

The wave washer 55 is a washer shaped like a flat washer bent into a bow (wave shape). In this embodiment, the wave washer 55 is used not to provide the original function of a washer, which is to prevent loosening, but to provide a torque limiter function that utilizes the elastic force generated when the washer is compressed in the thickness direction and its shape is deformed, as described below. The wave washer 55 has a smaller axial dimension than, for example, a spring coil that generates an elastic force, and this also contributes to the miniaturization of the first drive unit 50 and, in turn, the variable lighting device 10.

In the assembled state of the first drive unit 50 as shown in FIG. 8, the worm wheel 52b is disposed on the bearing 56, the wave washer 55 is disposed on the worm wheel 52b, and the nut 54 is disposed on the wave washer 55. That is, the worm wheel 52b and the wave washer 55 are fitted into the first output shaft 53, the nut 54 is screwed onto the first output shaft 53, and the axial positions of the bearing 56, the worm wheel 52b, the wave washer 55, and the nut 54 are disposed in a state where they coincide with the axial position of the first output shaft 53.

In addition, because the nut 54 is screwed onto the first output shaft 53 and tightened, the worm wheel 52b and the wave washer 55 are sandwiched between the nut 54 and the bearing 56. As a result, the lower end face of the wave washer 55 is in sliding contact with the upper end face of the worm wheel 52b, and the lower end face of the nut 54 is in sliding contact with the upper end face of the wave washer 55. Note that, in this case, "upper side" refers to the side away from the housing 50a, and "lower side" refers to the side closer to the housing 50a.

When assembling the first drive unit 50, the nut 54 is screwed (tightened) onto the first output shaft 53 with the worm wheel 52b and wave washer 55 interposed between the nut 54 and the bearing 56. As the nut 54 is tightened, the wave washer 55 is sandwiched between the nut 54 and the worm wheel 52b and compressed in the axial direction (in the plate thickness direction of the washer) to deform the washer shape, causing the wave washer 55 to generate a resilient force along the axial direction. The resilient force of the wave washer 55 presses the wave washer 55 and nut 54 together with an appropriate contact pressure, and the wave washer 55 and worm wheel 52b together with an appropriate contact pressure. Once the proper pressure contact state has been achieved, the tightening of the nut 54 is stopped, and a set screw 54b (Figure 8) is screwed into the horizontal hole 54a (Figure 7) formed in the nut 54 to secure the nut 54 to the first output shaft 53 so that the nut 54 does not rotate relative to the first output shaft 53.

In this first drive unit 50, simply by changing the amount by which the nut 54 is screwed (tightened) onto the first output shaft 53, the compression state of the wave washer 55 and, in turn, the elastic force generated by the wave washer 55 changes according to the change in shape of the wave washer 55, and the contact pressure between the wave washer 55 and the nut 54, and the contact pressure between the wave washer 55 and the worm wheel 52b change. In other words, the "screw-in type compression structure" in which the nut 54 is screwed onto the first output shaft 53, which has a male thread, makes it possible to easily adjust the compression state of the wave washer 55 and, in turn, the elastic force generated by the wave washer 55.

Therefore, by simply adjusting the amount by which the nut 54 is screwed (tightened) onto the first output shaft 53, the contact pressure between the wave washer 55 and the nut 54, and the contact pressure between the wave washer 55 and the worm wheel 52b can be easily set (adjusted) to an appropriate contact pressure.
Furthermore, even after the contact pressure has been set, the contact pressure between the wave washer 55 and the nut 54, and the contact pressure between the wave washer 55 and the worm wheel 52b can be easily changed by removing the set screw 54b (Figure 8) from the horizontal hole 54a (Figure 7) and changing the amount of screwing (amount of tightening) of the nut 54 onto the first output shaft 53.

As described above, the wave washer 55 and the nut 54 are in pressure contact, and the wave washer 55 and the worm wheel 52b are in pressure contact, so the rotational force generated by the rotation motor 51 is transmitted to the first output shaft 53 via the path worm 52a → worm wheel 52b → wave washer 55 → nut 54, and the first output shaft 53 rotates. The rotational force of the first output shaft 53 is transmitted to the arm 40 and thus to the lamp 30, and the arm 40 and thus the lamp 30 rotate relative to the base 20.

On the other hand, when the swivel motor 51 is rotating and the lamp 30 etc. is rotating, if the lamp 30 or the arm 40 collides with an obstacle or the like and becomes unable to move, an excessive torque exceeding a first specified torque (described later) set in advance is applied to the first drive unit 50. Also, when the swivel motor 51 is stopped and the lamp 30 or the arm 40 is manually rotated, an excessive torque exceeding a first specified torque set in advance is applied to the first drive unit 50. When an excessive torque exceeding the first specified torque is applied to the first drive unit 50 in this way, slip occurs between the wave washer 55 and the worm wheel 52b and between the wave washer 55 and the nut 54. In other words, a first torque limiter structure is formed by the structure including the wave washer 55, and this first torque limiter structure is interposed between the swivel motor 51 and the first output shaft 53.

As described above, the first torque limiter structure is configured by clamping the wave washer 55 in a compressed state between the nut 54 and the worm wheel 52b. A first specified torque according to the compressed state of the wave washer 55 is set in this first torque limiter structure. The first specified torque is greater than the output torque of the turning motor 51 transmitted via the first output shaft 53, and is smaller than the torque applied to the first torque limiter structure when the operator manually adjusts the turning angle of the lamp 30, etc., or when the lamp 30, etc. collides with an obstacle, etc. while turning and becomes unable to move.

As described above, the first specified torque is set to be greater than the output torque (lower limit torque) of the rotation motor 51 transmitted via the first output shaft 53 and smaller than the torque (upper limit torque) applied to the first torque limiter structure by manually adjusting the rotation angle of the lamp 30, etc. For this reason, for example, when it is desired to smoothly change the rotation angle of the lamp 30, etc. by manual adjustment, the first specified torque can be set to a torque value as close as possible to the lower limit torque, so that manual adjustment can be easily performed. Also, for example, when it is desired to maintain the contact state between the wave washer 55 and the worm wheel 52b or the contact state between the wave washer 55 and the nut 54 even if the lamp 30, etc., lightly contacts an obstacle, etc. while the lamp 30, etc. is rotating, the first specified torque can be set to a torque value as close as possible to the upper limit torque.

In addition, when the elastic force generated by the wave washer 55 weakens due to aging or other reasons, the elastic force generated by the wave washer 55 can be easily restored to an appropriate elastic force by increasing the amount of tightening of the nut 54 onto the first output shaft 53.

In place of the wave washer 55, a spring washer (a washer with a shape that looks like a flat washer with part of it broken off and twisted) or a disc spring washer can be used. In other words, a type of washer that generates a resilient force by deforming its shape when compressed in the plate thickness direction can be used. Also, instead of a washer such as the wave washer 55, other elastic members such as a coil spring or a leaf spring can be used. Furthermore, instead of using the wave washer 55, a commercially available mechanical torque limiter (a torque limiter using a spring material) or a magnetic torque limiter can be incorporated.

[Configuration of turning angle detection sensor, etc.]
As shown in Figs. 8 and 9, a magnet mounting arm 57 is integrated with the nut 54. The magnet mounting arm 57 rises upward from the nut 54 and has a bent shape that is bent at multiple points, and its tip 57a is located above the rotation axis of the first output shaft 53, the worm wheel 52b, the wave washer 55, and the nut 54, which are rotating members. A disk-shaped magnet 58a is attached to the tip 57a of the magnet mounting arm 57. As shown in Fig. 10, the magnet 58a is a two-pole magnet, with a semicircular portion being the N pole and the remaining semicircular portion being the S pole. Furthermore, as shown in Fig. 9, a magnetic encoder 58b is disposed opposite the magnet 58a. In other words, the magnet 58a and the magnetic encoder 58b form a rotation angle detection sensor 58 that detects the rotation angle of the first output shaft 53, and therefore the arm 40 and the lamp 30.

The magnetic encoder 58b is configured with an encoder section on a substrate, and the encoder section has built-in magnetic sensors such as Hall elements and MR elements (Magneto Resistive Sensors), which detect changes in the magnetic field caused by the rotation of the magnet 58a and convert them into an electrical signal. The rotation angle detection sensor 58 outputs a rotation angle detection signal corresponding to the rotation angle of the arm 40 (first output shaft 53) and the lamp 30 relative to the base 20 based on the electrical signal output from the magnetic sensor.

[Configuration of the second driving unit, etc.]
2 to 4, the second drive unit 60 is attached to the lamp 30. That is, a housing 60a of the second drive unit 60 is attached to the front cylinder portion 31 of the lamp 30. This second drive unit 60 has a configuration similar to that of the first drive unit 50. That is, as shown in FIG. 11, the second drive unit 60 has a swiveling motor 61, which is a brushed DC motor provided in a housing 60a, a worm gear 62 consisting of a worm 62a and a worm wheel 62b, a second output shaft 63 formed with a male thread, a nut 64 having a horizontal hole 64a and a set screw 64b, and a wave washer 65 (not shown).

In other words, the second drive unit 60 has a swing motor 61 equivalent to the swivel motor 51, a worm gear 62 consisting of a worm 62a and a worm wheel 62b equivalent to the worm gear 52 consisting of a worm 52a and a worm wheel 52b, a second output shaft 63 equivalent to the first output shaft 53, a nut 64 having a horizontal hole 64a and a set screw 64b equivalent to the nut 54 having a horizontal hole 54a and a set screw 54b, a wave washer 65 (not shown) equivalent to the wave washer 55, and a bearing 66 (not shown) equivalent to the bearing 56.

In the end, in the second drive unit 60, similar to the first drive unit 50, the worm wheel 62b is disposed on the bearing 66 (not shown), the wave washer 65 (not shown) is disposed on the worm wheel 62b, and the nut 64 is disposed on the wave washer 65 (not shown). That is, the worm wheel 62b and the wave washer 65 (not shown) are fitted into the second output shaft 63, the nut 64 is screwed onto the second output shaft 63, and the axial positions of the bearing 66 (not shown), the worm wheel 62b, the wave washer 65 (not shown), and the nut 64 are disposed in a state where they coincide with the axial position of the second output shaft 63.

The second output shaft 63 of the second drive unit 60 is positioned coaxially with the support shaft 71 of the pivot support unit 70 (Figure 5), and is integrated with the vertical shaft portion 42a of the arm 40 (Figure 5).

Because of this configuration, the rotational force generated by the oscillation motor 61 is transmitted to the second output shaft 63 via the worm 62a → worm wheel 62b → wave washer 65 (not shown) → nut 64. Since the second output shaft 63 is integral with the vertical shaft portion 42a of the arm 40, the second drive unit 60 (oscillating motor 61) side rotates (oscillates) relative to the second output shaft 63 (arm 40). In other words, the lamp 30 to which the second drive unit 60 is attached rotates (oscillates) relative to the arm 40.

On the other hand, when the oscillation motor 61 rotates and the lamp 30 etc. oscillates, if the lamp 30 collides with an obstacle or the like and becomes unable to move, an excessive torque exceeding the preset second specified torque (described later) is applied to the second drive unit 60. Also, when the oscillation motor 61 is stopped and the lamp 30 is oscillated by manual operation, an excessive torque exceeding the preset second specified torque is applied to the second drive unit 60. When an excessive torque exceeding the second specified torque is applied to the second drive unit 60 in this way, slip occurs between the wave washer 65 (not shown) and the worm wheel 62b, and between the wave washer 65 (not shown) and the nut 64. In other words, a second torque limiter structure is formed by a structure including the wave washer 65 (not shown), and this second torque limiter structure is interposed between the oscillation motor 61 and the second output shaft 63.

In the second drive unit 60, as in the first drive unit 50, a second torque limiter structure is formed by clamping a wave washer 65 (not shown) in a compressed state between a nut 64 and a worm wheel 62b. A second specified torque according to the compressed state of the wave washer 65 (not shown) is set in this second torque limiter structure. The second specified torque is greater than the output torque of the oscillation motor 61 transmitted via the second output shaft 63, and is smaller than the torque applied to the second torque limiter structure when the operator manually adjusts the oscillation angle of the lamp 30, or when the lamp 30 collides with an obstacle or the like while oscillating and becomes unable to move.

In the second drive unit 60, just as in the first drive unit 50, simply changing the amount by which the nut 64 is screwed onto the second output shaft 63 (the amount by which it is tightened) changes the elastic force generated by the wave washer 65 (not shown), and changes the contact pressure between the wave washer 65 (not shown) and the nut 64, and the contact pressure between the wave washer 65 (not shown) and the worm wheel 62b.

Therefore, by simply adjusting the amount by which the nut 64 is screwed onto the second output shaft 63 (the amount by which it is tightened), the contact pressure between the wave washer 65 (not shown) and the nut 64, and the contact pressure between the wave washer 65 (not shown) and the worm wheel 62b can be easily set to appropriate contact pressures.
Furthermore, even after the contact pressure has been set, the contact pressure between the wave washer 65 (not shown) and the nut 64, and the contact pressure between the wave washer 65 (not shown) and the worm wheel 62b can be easily changed by removing the set screw 64b (Figure 11) from the horizontal hole 64a (Figure 11) and changing the amount of screwing (amount of tightening) of the nut 64 onto the second output shaft 63.

As described above, the second specified torque may be set to be greater than the output torque (lower limit torque) of the oscillation motor 61 transmitted via the second output shaft 63 and smaller than the torque (upper limit torque) applied to the second torque limiter structure by manually adjusting the oscillation angle of the lamp 30. For this reason, for example, if it is desired to smoothly change the oscillation angle of the lamp 30 by manual adjustment, the second specified torque may be set to a torque value as close as possible to the lower limit torque, so that manual adjustment can be easily performed. Also, for example, if it is desired to maintain the contact state between the wave washer 65 (not shown) and the worm wheel 62b or the contact state between the wave washer 65 (not shown) and the nut 64 even if the lamp 30 lightly contacts an obstacle or the like while the lamp 30 is oscillating, the second specified torque may be set to a torque value as close as possible to the upper limit torque.

In addition, when the elastic force generated by the wave washer 65 (not shown) weakens due to aging or other reasons, the elastic force generated by the wave washer 65 (not shown) can be easily restored to an appropriate elastic force by increasing the amount of tightening of the nut 64 onto the second output shaft 63.

In addition, instead of the wave washer 65 (not shown), a spring washer (a washer with a shape that looks like a flat washer with part of it broken off and twisted) or a disc spring washer can be used. In other words, a type of washer that generates a resilient force by deforming the shape of the washer when compressed in the plate thickness direction can be used. Also, instead of a washer such as the wave washer 65 (not shown), other elastic members such as a coil spring or a leaf spring can be used. Furthermore, instead of a washer such as the wave washer 65 (not shown), a commercially available mechanical torque limiter (torque limiter using a spring material) or a magnetic torque limiter can be incorporated.

[Configuration of the swing angle detection sensor, etc.]
11, the oscillation angle detection sensor 68 has a magnet 68a attached to the tip surface of the second output shaft 63 and a magnetic encoder 68b (not shown) facing the magnet 68a at a predetermined distance. The oscillation angle detection sensor 68 outputs an oscillation angle detection signal corresponding to the rotation angle of the lamp 30 relative to the arm 40 (second output shaft 63, support shaft 71) and the base unit 20.

[Cable configuration, etc.]
As shown in Figs. 3 and 4, the cable 80 is wired so that it passes through an insertion hole formed in the first output shaft 53 of the first drive unit 50 from inside the base unit 20, and then goes out to the external space and enters the inside of the lamp 30. As shown in Fig. 12, the cable 80 is a protective tube 82 covering a dozen or so internal electric wires 81 that transmit currents and signals between the base unit 20 and the lamp 30 or the second drive unit 60. The protective tube 82 is a tubular member in which a twisted yarn made of nylon 66 yarn and a polyethylene terephthalate (PET) yarn are twisted together and woven into a braided structure, or a tubular member in which a twisted yarn made of nylon 66 yarn and a polyethylene terephthalate (PET) yarn are woven into a braided structure. The protective tube 82 is made of materials made of nylon 66 and polyethylene terephthalate (PET), and therefore has high slipperiness, shape retention, stretchability, and flexibility. Therefore, even if the lighting fixture 30 rotates or oscillates, the protective tube 82 flexibly responds to such movements and deforms, and at this time, the internal wire 81 can easily slide relative to the protective tube 82. This makes it difficult for the internal wire 81 to be twisted, pulled, or bent, thereby reducing damage to the internal wire 81 and preventing breakage of the internal wire 81.

[Explanation of the control system built into the variable lighting device]
As shown in FIG. 13, the base section 20 of the variable lighting device 10 includes therein a communication module 201, a control section 202, a memory 203, a power supply section 204, a power supply control section 205, and various other control sections 210-213 and 220-223.

The communication module 201 can perform two-way wireless communication with a tablet 90, which is a remote control terminal. Furthermore, in the lighting system LS shown in FIG. 1, the communication modules 201 of the 12 variable lighting devices 10 are capable of two-way wireless communication with adjacent ones, thereby forming a mesh network MN.

The control unit 202 transmits and receives information to and from the communication module 201 and performs overall control of the variable lighting device 10 .
The memory 203 stores information sent from the communication module 201 via the control unit 202, as well as various information and programs required to operate the variable lighting device 10. Furthermore, the memory 203 stores the group ID of the group to which the variable lighting device 10 belongs.

The power supply unit 204 converts AC voltage supplied from a duct plug (not shown) or the like into DC voltage, and supplies the DC voltage converted to an appropriate voltage value to the light source 36 and various motors 38 , 51 , 61 .
The power supply control unit 205 controls the operation of the power supply unit 204 .

The control units 210 to 213 control the light source 36. More specifically, the on/off control unit 211 controls the on/off of the light source 36, the dimming control unit 212 controls the dimming of the light source 36, and the color adjustment control unit 213 controls the color adjustment of the light source 36.

The control units 220 to 223 control the motors 38, 51, and 61 to control the rotation operation, the oscillating operation, and the light distribution angle. Specifically, the pan control unit 221 controls the drive of the rotation motor 51 to control the rotation operation of the lamp 30, the tilt control unit 222 controls the drive of the oscillating motor 61 to control the oscillating operation of the lamp 30, and the light distribution angle control unit 223 controls the drive of the lens movement motor 38 to control the light distribution angle.

The variable lighting device 10 sends, for example, the following detection signal to the tablet 90 via the communication module 201.
Turning angle detection signal D1
The rotation angle detection signal D1 is output from a rotation angle detection sensor 58 provided in the first drive unit 50. This rotation angle detection signal D1 has the rotation angle of the lamp 30 relative to the base unit 20 as information.
Swing angle detection signal D2
The oscillation angle detection signal D2 is output from an oscillation angle detection sensor 68 provided in the second drive unit 60. This oscillation angle detection signal D2 has the oscillation angle of the lamp 30 relative to the base unit 20 as information.
Light distribution angle detection signal D3
The light distribution angle detection signal D3 is output from a lens position detection sensor 39 provided in the lamp 30. Since the movement position of the lens 33 corresponds to the light distribution angle, the lens position detection sensor 39 outputs a light distribution angle detection signal D3 having information on the light distribution angle based on the detected movement position of the lens 33.

[Tablet Description]
The tablet 90 is, for example, a touch panel display type remote control terminal, and sends, for example, the following control signal to a communication module 201 provided on the base unit 20 of the variable lighting device 10.
Turn control signal C1
The rotation control signal C1 has information on the rotation angle (for example, 0° to 360°) of the lamp 30. A rotation angle of 0° is an angle at which the lamp 30 is located at the origin position on the rotation plane. The state in which the lamp 30 is located at the origin position on the rotation plane will be described later.
Swing control signal C2
The oscillation control signal C2 has as information the oscillation angle (for example, 0° to 90°) of the lighting fixture 30. An oscillation angle of 0° is an angle at which the light emitted from the lighting fixture 30 travels vertically from the ceiling surface side to the floor surface side, and an oscillation angle of 90° is an angle at which the light emitted from the lighting fixture 30 travels in a direction parallel to the ceiling surface as shown in FIG.
Light distribution angle control signal C3
The light distribution angle control signal C3 has information on the light distribution angle (for example, 16° to 47°) of the light emitted from the lighting fixture 30.
Light-on/light-off control signal C4
The on/off control signal C4 has as information a turn-on instruction or a turn-off instruction for instructing whether to turn on or turn off the light source (LED) 36 provided in the lamp 30.
Dimming control signal C5
The dimming control signal C5 has dimming degree (for example, 100% to 1%) as information.
Color matching control signal C6
The color adjustment control signal C6 has information on the color adjustment level (for example, neutral white (5000k) to incandescent light (2700k)).

Here, the state where the lamp 30 is located at the origin position on the rotation plane will be described. The lamp 30 rotates in a horizontal plane, and the state where the lamp 30 is located at the origin position (rotation angle 0°) on the rotation plane (horizontal plane) is as follows.
As shown in Figure 2, when the front tube portion 31 of the lamp 30 faces the left side of the base portion 20, the rear tube portion 32 of the lamp 30 faces the right side of the base portion 20, and the axial direction of the lamp 30 and the longitudinal direction of the base portion 20 coincide in a plan view (when the variable lighting device 10 shown in Figure 2 is viewed from above), the lamp 30 is said to be located at the origin position on the rotation plane.

In addition, the tablet 90 outputs an angle registration command signal α when registering an angle (described later), outputs a registered angle playback command signal β when playing back a registered angle (described later), outputs a scene registration command signal γ when registering a scene (described later), and outputs a registered scene playback command signal δ when playing back a registered scene (described later).

In the lighting system LS shown in FIG. 1, the multiple (12) variable lighting devices 10 have device IDs No. 1 to No. 12 to identify them, as described above. These variable lighting devices 10 belong to a specific group, and each variable lighting device 10 has a group ID of the group to which it belongs. When it is desired to control a variable lighting device 10 that belongs to a specific group, the group ID of that group is set in the tablet 90. When the group ID of a specific group is set in the tablet 90 in this way, the above-mentioned control signals C1 to C6, the angle registration command signal α and the scene registration command signal γ, the registered angle playback command signal β and the registered scene playback command signal δ are linked (added) to the group ID information representing the set group ID and output.

[Tablet operation screen explanation]
A plurality of setting screens can be displayed by switching the display screen on the operation display screen 91 of the tablet 90. Here, an angle setting screen for setting the rotation angle, the oscillation angle, and the light distribution angle, a scene setting screen for setting the dimming, the color adjustment, and the on/off of the light, and a timer setting screen for setting the timer execution time will be described.

[Angle setting screen]
14 shows an angle setting screen. On this angle setting screen, the rotation angle of the lamp 30 can be set by operating a GUI (Graphical User Interface) control 901, and a rotation control signal C1 having the set rotation angle as information is output. The GUI control 901 may be a circular graphic display (figure display) from 0° to 360° or an upward and downward triangular arrow, either of which may be used. The GUI control 901 displays the set rotation angle as a number.

By operating the GUI control 902, the oscillation angle of the lamp 30 can be set, and an oscillation control signal C2 containing the set oscillation angle as information is output. The GUI control 902 comes in two varieties: a graphic display (figure display) of 0° to 90° on an arc, and an upward and downward triangular arrow, but either can be used. The set oscillation angle is displayed numerically on this GUI control 902.

By operating the GUI control 903, the light distribution angle of the light output from the lighting fixture 30 can be set, and a light distribution angle control signal C3 containing the set light distribution angle as information is output. The GUI control 903 comes in two types: a radial graphic display (graphical display) illustrating the light distribution angle state, and an upward and downward triangular arrow, but either can be used. This GUI control 903 displays the set light distribution angle as a number.

Furthermore, after setting the rotation angle, the oscillation angle, and the light distribution angle, by tapping the angle saving GUI control 904, the set rotation angle, the oscillation angle, and the light distribution angle can be registered (stored) in the tablet 90 as angle registration A. At this time, an angle registration command signal αA is sent from the tablet 90 to each variable lighting device 10 in the mesh network MN.
After setting the rotation angle, the oscillation angle, and the light distribution angle to different values, by tapping the angle saving GUI control 904, the rotation angle, the oscillation angle, and the light distribution angle set to different values can be registered (stored) in the tablet 90 as angle registration B. At this time, an angle registration command signal αB is sent from the tablet 90 to each variable lighting device 10 in the mesh network MN.
In the same manner, another angle registration C can be registered (stored) etc. By registering angles in this manner, A, B, C etc. are displayed on the GUI controls 905, 906, 907 etc.

In the lighting system LS shown in FIG. 1, when an angle registration command signal αA is output from the tablet 90, for example, angle registration A is registered in the variable lighting device 10 of the first group. Also, when an angle registration command signal αB is output from the tablet 90, for example, angle registration B is registered in the variable lighting device 10 of the second group.

After registering angle registration A, when the GUI control 905 indicating angle registration A is tapped, the rotation angle, the oscillation angle, and the light distribution angle set and registered as angle registration A are displayed on each of the GUI controls 901, 902, and 903. At this time, a registered angle reproduction command signal βA is sent from the tablet 90 to each variable lighting device 10 in the mesh network MN.
Similarly, after registering angle registration B, when the GUI control 906 indicating angle registration B is tapped, the rotation angle, the oscillation angle, and the light distribution angle set and registered as angle registration B are displayed on each of the GUI controls 901, 902, and 903. At this time, a registered angle reproduction command signal βB is sent from the tablet 90 to each variable lighting device 10 in the mesh network MN.

1, when a registered angle reproduction command signal βA is output from the tablet 90, the registered angle reproduction command signal βA is received and captured, for example, by the first group of variable lighting devices 10. Then, the first group of variable lighting devices 10 controls the rotation angle, the tilt angle, and the light distribution angle so that the angle of the device coincides with the angle registered as angle registration A.
Furthermore, when the registered angle reproduction command signal βB is output from the tablet 90, the registered angle reproduction command signal βB is received and captured, for example, by the second group of variable lighting devices 10. Then, the second group of variable lighting devices 10 controls the rotation angle, the tilt angle, and the light distribution angle so that the angle of the device coincides with the angle registered as the angle registration B.

[Scene setting screen]
15 shows a dimming setting screen for setting dimming among the scene setting screens. In this dimming setting screen, the dimming level (100% to 1%) can be set by operating a GUI control 921, and a dimming control signal C5 containing the set dimming level as information is output. The GUI control 921 is a graphic display (graphical display) in which a round dot knob is slid along a straight line extending up and down. The set dimming level is displayed numerically in this GUI control 921.

16 is a screen for setting color adjustment, dimming, and turning on/off of the scene setting screen. In this setting screen, the color adjustment level (500k to 2700k) can be set by operating the GUI control 922, and a color adjustment control signal C6 having the set color adjustment level as information is output. The GUI control 922 is a graphic display (figure display) in which a double circle knob is arranged inside a square frame, and the more the double circle knob is turned to the right, the darker the daylight white can be set, and the more the double circle knob is turned to the left, the darker the light bulb color can be set. In addition to color adjustment, this GUI control 922 can also set dimming at the same time, and the more the double circle knob is turned to the upper side, the brighter the brightness can be set, and the more the double circle knob is turned to the lower side, the weaker the brightness can be set. In this GUI control 922, the color adjustment level is displayed depending on the left and right positions of the double circle knob, and the dimming level is displayed in numbers depending on the up and down positions of the double circle knob.
By operating (tapping) the GUI controls 923a and 923b, the light can be set to be on or off, and a light on/off control signal C4 having a light on instruction or a light off instruction as information is output.

Furthermore, after setting the dimming level and color adjustment level, by tapping the GUI control 924 ( FIG. 15 ) for saving a scene, the set dimming level and color adjustment level can be registered (stored) in the tablet 90 as scene registration 1. At this time, a scene registration command signal γ1 is sent from the tablet 90 to each variable lighting device 10 in the mesh network MN.
After setting the dimming level and the color adjustment level to different values, the user can tap the GUI control 924 to register (store) the set dimming level and the color adjustment level to different values in the tablet 90 as scene registration 2. At this time, a scene registration command signal γ2 is sent from the tablet 90 to each variable lighting device 10 in the mesh network MN.
As scenes are registered in this manner, the display of GUI controls 925 and 926 displaying scene registrations 1, 2, etc. changes from "Not Set" to "Set."

In the lighting system LS shown in FIG. 1, when a scene registration command signal γ1 is output from the tablet 90, scene registration 1 is registered in the variable lighting device 10 of the first group, for example. When a scene registration command signal γ2 is output from the tablet 90, scene registration 2 is registered in the variable lighting device 10 of the second group, for example.

After registering scene registration 1, when the GUI control 925 indicating scene registration 1 is tapped, the dimming level and the color level set and registered as scene registration 1 are displayed on each of the GUI controls 921 and 922. At this time, a registered scene playback command signal δ1 is sent from the tablet 90 to each variable lighting device 10 in the mesh network MN.
Similarly, after registering scene registration 2, when the GUI control 926 indicating scene registration 2 is tapped, the dimming level and the color level set and registered as scene registration 2 are displayed on each of the GUI controls 921 and 922. At this time, a registered scene playback command signal δ2 is transmitted from the tablet 90 to each of the variable lighting devices 10 in the mesh network MN.

1, when a registered scene reproduction command signal δ1 is output from the tablet 90, the registered scene reproduction command signal δ1 is received and captured, for example, by the first group of variable lighting devices 10. Then, the first group of variable lighting devices 10 controls turning on/off, dimming, and color adjustment so that the scene of the device matches the scene registered as scene registration 1.
Furthermore, when the registered scene reproduction command signal δ2 is output from the tablet 90, the registered scene reproduction command signal δ2 is received, for example, by the variable lighting device 10 of the second group. Then, the variable lighting device 10 of the second group controls turning on/off, dimming, and adjusting the color so that the scene of the device matches the scene registered as scene registration 2.

[Display of set group ID information, etc.]
The operator can operate the tablet 90 to set the “Place” and “Group ID information” in the tablet 90 .
As for the place, for example, the mesh network MN shown in FIG. 1 can be set as the place P1, and another network not shown can be set as the place P2.
There may be multiple groups in each place (mesh network MN). For example, in place P1 (mesh network MN), variable lighting devices 10 No. 1 to No. 6 may be in the first group, and variable lighting devices 10 No. 7 to No. 12 may be in the second group. In this case, group ID information such as group ID=G1 or group ID=G2 may be set in the tablet 90.

When the place P is set, the set place is displayed as "P1" or "P2" in the display section DP on the angle setting screen in FIG. 14, the scene setting screen in FIG. 15, and the scene setting screen in FIG.
Also, for example, when two group ID information are set, the set group ID information is displayed as "G1" and "G2" on the display unit DG on the angle setting screen of FIG. 14 and the scene setting screen of FIG.
Furthermore, for example, when group ID information for the first group is set, the MAC address (Media Access Control Address) corresponding to the device ID of each variable lighting device 10 constituting the first group is displayed on the display unit DM on the angle setting screen of FIG. 14 .

[Timer setting screen]
17 and 18 show timer setting screens.
First, to select a scene, the user uses the scene selection button 931 in Fig. 17 to select the desired lighting state from ALL ON/ALL OFF, or from pre-registered scene registrations 1 to 5. Here, the following explanation will be given assuming that scene registration 1 has been selected.
Next, to select an angle, the user presses the angle selection button 932 in Fig. 18 to select a desired angle from among the previously registered angles A to C. Here, the following explanation will be given assuming that the angle registration A has been selected.

For example, after selecting scene registration 1 and angle registration A, the time designation unit 933 is used to designate the timer execution time using a 24-hour time axis, and the time designation unit 934 is used to designate the timer execution time (e.g., timer execution time T1) in hours and minutes scrolled up and down in the smallest units.
Furthermore, the timer execution date designation section 935 can be used to designate Sunday through Saturday individually, or every day, or to designate whether the timer is to be executed repeatedly or not.

When the save button 936 is pressed, the timer setting conditions selected as described above (e.g.,
The condition that links (adds) scene registration 1 and angle registration A to timer execution time T1 on Monday is confirmed, and the specified timer setting condition is stored in the memory of tablet 90. When cancel button 937 is pressed, the timer setting condition is canceled.
The above timer setting conditions can be set either alone or in combination.

After setting the timer setting conditions in this manner, when the timer execution time arrives, a registered scene playback command signal δ1 corresponding to scene registration 1 and a registered angle playback command signal βA corresponding to angle registration A are output from the tablet 90.

[Explanation of remote control of variable lighting device using tablet]
The following describes a control operation for remotely controlling the variable lighting devices 10 using the tablet 90. Note that the following description illustrates a control operation performed between the tablet 90 and the variable lighting devices 10 that belong to a predetermined group among the multiple variable lighting devices 10 in the lighting system LS shown in FIG.

By operating the GUI control 901 (FIG. 14), a rotation control signal C1 having information on the set rotation angle is sent from the tablet 90. The communication module 201 (FIG. 13) provided in the base unit 20 of the variable lighting device 10 receives the rotation control signal C1 sent from the tablet 90.
The control unit 202 (FIG. 13) receives information on the set rotation angle contained in the rotation control signal C1 from the communication module 201, and sends this to the attitude control unit 220. The attitude control unit 220 drives the rotation motor 51 according to the set rotation angle via the pan control unit 221, thereby rotating the arm 40 and ultimately the lighting device 30. When the lighting device 30 rotates, a rotation angle detection signal D1 is fed back from the rotation angle detection sensor 58 to the pan control unit 221, and when the rotation angle of the lighting device 30 reaches the set rotation angle, the driving of the rotation motor 51 is stopped.

By operating the GUI control 902 (FIG. 14), a swing control signal C2 having information on the set swing angle is sent from the tablet 90. The communication module 201 (FIG. 13) provided in the base unit 20 of the variable lighting device 10 receives the swing control signal C2 sent from the tablet 90.
The control unit 202 (FIG. 13) receives information on the set oscillation angle contained in the oscillation control signal C2 from the communication module 201, and sends this to the attitude control unit 220. The attitude control unit 220 drives the oscillation motor 61 to the set oscillation angle using the tilt control unit 222, thereby oscillating the lamp 30. When the lamp 30 oscillates, the oscillation angle detection signal D2 is fed back from the oscillation angle detection sensor 68 to the tilt control unit 222, and when the oscillation angle of the lamp 30 reaches the set oscillation angle, the driving of the oscillation motor 61 is stopped.

By operating the GUI control 903 (FIG. 14), a light distribution angle control signal C3 having information on the set light distribution angle is sent from the tablet 90. The communication module 201 (FIG. 13) provided in the base unit 20 of the variable lighting device 10 receives the light distribution angle control signal C3 sent from the tablet 90.
The control unit 202 (FIG. 13) receives information on the set light distribution angle contained in the light distribution angle control signal C3 from the communication module 201, and sends this to the attitude control unit 220. The attitude control unit 220 drives the lens moving motor 38 in accordance with the set light distribution angle by the light distribution angle control unit 223, thereby moving the lens 33. When the lens 33 moves, a light distribution angle detection signal D3 is fed back from the lens position detection sensor 39 to the light distribution angle control unit 223, and when the light distribution angle of the light emitted from the lamp 30 becomes the set light distribution angle, the driving of the lens moving motor 38 is stopped.

By operating the GUI control 923a (FIG. 16), pan and tilt having lighting instruction information are sent from the tablet 90. The communication module 201 (FIG. 13) provided in the base unit 20 of the variable lighting device 10 receives the on/off control signal C4 sent from the tablet 90.
The control unit 202 (FIG. 13) receives the turn-on instruction information contained in the turn-on/turn-off control signal C4 from the communication module 201, and sends this to the light source control unit 210. The light source control unit 210 turns on the light source (LED) 36 using the turn-on/turn-off control unit 211.

By operating the GUI control 923b (FIG. 16), a light-on/light-off control signal C4 having a light-off instruction as information is sent from the tablet 90. The communication module 201 (FIG. 13) provided in the base unit 20 of the variable lighting device 10 receives the light-on/light-off control signal C4 sent from the tablet 90.
The control unit 202 (FIG. 13) receives the information on the turn-off instruction contained in the light-on/off control signal C4 from the communication module 201, and sends this to the light source control unit 210. The light source control unit 210 causes the light source (LED) 36 to be turned off by the light-on/off control unit 211.

By operating the GUI control 921 (FIG. 15) or the GUI control 922 (FIG. 16), a dimming control signal C5 having information on the set dimming level is sent from the tablet 90. The communication module 201 (FIG. 13) provided in the base unit 20 of the variable lighting device 10 receives the dimming control signal C5 sent from the tablet 90.
The control unit 202 (FIG. 13) receives information indicating the dimming level contained in the dimming control signal C5 from the communication module 201, and sends this information to the light source control unit 210. The light source control unit 210 controls the dimming level of the light source (LED) 36 to the set dimming level by the dimming control unit 212.

By operating the GUI control 922 (FIG. 16), a color tuning control signal C6 having information on the set color tuning level is sent from the tablet 90. The communication module 201 (FIG. 13) provided in the base unit 20 of the variable lighting device 10 receives the color tuning control signal C6 sent from the tablet 90.
The control unit 202 (FIG. 13) receives information indicating the toning degree contained in the toning control signal C6 from the communication module 201, and sends this to the light source control unit 210. The light source control unit 210 controls the toning degree of the light source (LED) 36 by the toning control unit 213 to the set toning degree.

The control unit 202 (FIG. 13) stores in the memory 203 the final rotation angle, oscillation angle, and light distribution angle of the lamp 30 set through control by the control units 220 to 223, and also stores in the memory 203 the final on/off state, dimming level, and color adjustment level of the light source 36 set through control by the control units 210 to 213.

Furthermore, the rotation angle detection signal D1 output from the rotation angle detection sensor 58, the oscillation angle detection signal D2 output from the oscillation angle detection sensor 68, and the light distribution angle detection signal D3 output from the lens position detection sensor 39 are sent from the communication module 201 (variable lighting device 10) to the tablet 90 by the control unit 202. This signal sending is performed, for example, continuously in time or at predetermined time intervals.
The tablet 90 receives the rotation angle detection signal D1, the oscillation angle detection signal D2, and the light distribution angle detection signal D3 sent from the variable lighting device 10, and thereby recognizes the rotation angle, oscillation angle, and light distribution angle of the lighting fixture 30.

[Explanation of operation state when registering an angle]
To register an angle, first, the attitude (rotation angle and oscillation angle) and light distribution angle, which are the positions of the lighting fixture 30, are preset. Specifically, the variable lighting device 10 is remotely controlled using the tablet 90 to adjust the attitude (rotation angle and oscillation angle) of the lighting fixture 30 and the light distribution angle of the emitted light, or the attitude (rotation angle and oscillation angle) of the lighting fixture 30 of the variable lighting device 10 is manually adjusted, so that the light emitted from the lighting fixture 30 is directed at the target position of the illuminated object.
In this state, by tapping the angle saving GUI control 904 (FIG. 14), the rotation angle, the oscillation angle, and the light distribution angle at that time are stored in the tablet 90 as angle registration A. At the same time, the tablet 90 sends an angle registration command signal αA to the variable lighting device 10.

The communication module 201 (FIG. 13) provided on the base unit 20 of the variable lighting device 10 receives the angle registration command signal αA sent from the tablet 90.
When the communication module 201 receives the angle registration command signal αA, the control unit 202 (FIG. 13) takes in the rotation angle obtained from the rotation angle detection signal D1, the oscillation angle obtained from the tilt angle detection signal D2, and the light distribution angle obtained from the light distribution angle detection signal D3, and stores these in the angle storage area of the memory 203 as the rotation angle, oscillation angle, and light distribution angle of angle registration A.

After setting the rotation angle, oscillating angle, and light distribution angle to different values, by tapping the GUI control 904 for saving angles, the rotation angle, oscillating angle, and light distribution angle set to different values are stored in the tablet 90 as angle registration B, and at the same time, an angle registration command signal αB is sent from the tablet 90 to the variable lighting device 10.
When the communication module 201 receives the angle registration command signal αB, the control unit 202 of the variable lighting device 10 takes in the rotation angle obtained from the rotation angle detection signal D1, the oscillation angle obtained from the oscillation angle detection signal D2, and the light distribution angle obtained from the light distribution angle detection signal D3, and stores these in an angle storage area of the memory 203 as the rotation angle, oscillation angle, and light distribution angle of angle registration B.

[Explanation of the operation state when playing back registered angles]
After registering angle registration A, when the GUI control 905 ( FIG. 14 ) indicating angle registration A is tapped, the rotation angle, the tilt angle, and the light distribution angle stored as angle registration A are displayed on each of the GUI controls 901, 902, and 903. At the same time, the tablet 90 sends a registered angle reproduction command signal βA to the variable lighting device 10.

The communication module 201 (FIG. 13) provided on the base unit 20 of the variable lighting device 10 receives the registered angle reproduction command signal βA sent from the tablet 90.
When the communication module 201 receives the registered angle reproduction command signal βA, the control unit 202 (FIG. 13) reads out the rotation angle, the tilt angle, and the light distribution angle of the registered angle A stored in the angle storage area of the memory 203.

The control unit 202 sends the rotation angle, the tilt angle, and the light distribution angle of the read angle registration A to the attitude control unit 220 .
The attitude control unit 220 first drives the rotation motor 51 via the pan control unit 221 to rotate the lighting fixture 30 to position it at the origin position on the rotation plane. When the lighting fixture 30 is thus positioned at the origin position on the rotation plane, the attitude control unit 220 drives the oscillation motor 61 via the tilt control unit 222 to set the oscillation angle of the lighting fixture 30 to the oscillation angle of the angle registration A.
Next, the attitude control unit 220 drives the rotation motor 51 via the pan control unit 221 to set the rotation angle of the lighting device 30 to the rotation angle of registered angle A.
Thereafter, the attitude control unit 220 causes the light distribution angle control unit 223 to set the light distribution angle of the light emitted from the lighting fixture 30 to the light distribution angle of registered angle A.

After registering angle registration B, when the GUI control 906 (Figure 14) indicating angle registration B is tapped, the same operation as when angle registration A is played back is performed.

In this way, when playing back the angle registration, the rotation and oscillating operations are performed with a time lag, and the oscillating operation is performed only when the lamp 30 is located at the origin position on the rotation plane. This makes it less likely that the internal wire 81 housed in the protective tube 82 of the cable 80 (Figures 3, 4, and 12) will be twisted, pulled, or bent, reducing damage to the internal wire 81 and preventing breakage of the internal wire 81.

[Explanation of the operation state when registering a scene]
To register a scene, first, the variable lighting device 10 is remotely controlled using the tablet 90 to set the dimming level and color adjustment level of the light emitted from the luminaire 30 to the target dimming level and color adjustment level.
In this state, by tapping the GUI control 924 (FIG. 15) for saving a scene, the dimming level and the color level at that time are stored in the tablet 90 as scene registration 1. At the same time, the tablet 90 sends a scene registration command signal γ1 to the variable lighting device 10.

The communication module 201 (FIG. 13) provided on the base unit 20 of the variable lighting device 10 receives the scene registration command signal γ 1 sent from the tablet 90 .
When the communication module 201 receives the scene registration command signal γ1, the control unit 202 (FIG. 13) acquires the dimming degree and color adjustment degree of the light emitted from the light source 36 from the dimming control unit 212 and the color adjustment control unit 213, and stores these in the scene memory area of the memory 203 as the dimming degree and color adjustment degree of scene registration 1.

After setting the dimming level and the color adjustment level to different values, by tapping the GUI control 924 for saving the scene, the dimming level and the color adjustment level set to different values are stored in the tablet 90 as scene registration 2, and at the same time, a scene registration command signal γ2 is sent from the tablet 90 to the variable lighting device 10.
When the communication module 201 receives the scene registration command signal γ2, the control unit 202 of the variable lighting device 10 acquires the dimming degree and color adjustment degree of the light emitted from the light source 36 from the dimming control unit 212 and the color adjustment control unit 213, and stores these in the scene memory area of the memory 203 as the dimming degree and color adjustment degree of scene registration 2.

[Explanation of the operation state when playing back scene registration]
After registering scene registration 1, when the GUI control 925 ( FIG. 15 ) indicating scene registration 1 is tapped, the dimming level and the toning level stored as scene registration 1 are displayed on the GUI controls 921 and 922. At the same time, the tablet 90 sends a registered scene playback command signal δ1 to the variable lighting device 10.

The communication module 201 (FIG. 13) provided on the base unit 20 of the variable lighting device 10 receives the registered scene reproduction command signal δ 1 sent from the tablet 90 .
When the communication module 201 receives the registered scene reproduction command signal δ 1 , the control unit 202 ( FIG. 13 ) reads out the dimming and color toning of registered scene 1 stored in the scene storage area of the memory 203 .

The control unit 202 sends the read dimming level and color level of scene registration 1 to the light source control unit 210. The light source control unit 210 adjusts the dimming level of the light source 36 to the dimming level of scene registration 1 using the dimming control unit 212. The light source control unit 210 also adjusts the color level of the light source 36 to the color level of scene registration 1 using the color adjustment control unit 213.

After registering scene registration 2, when you tap the GUI control 926 (Figure 15) that indicates scene registration 2, the same operation as when playing back scene registration 1 is performed.

[Explanation of the operating state when a lamp or the like collides with an obstacle]
The operating state will be described when the arm 40 or the lamp 30 collides with an obstacle during a rotational operation and is unable to perform the rotational operation, or when the lamp 30 collides with an obstacle during a swiveling operation and is unable to perform the swiveling operation.

The following describes the operating state when a rotation control signal C1 is sent from the tablet 90 (Figure 13) to the variable lighting device 10 and the arm 40 or the lamp 30 collides with an obstacle or the like while rotating and is no longer able to rotate.
In this case, excessive torque exceeding the first specified torque is applied from the arm 40 side to the first output shaft 53 side of the first drive unit 50 (FIGS. 7 and 8), causing slippage between the wave washer 55 and the worm wheel 52b and between the wave washer 55 and the nut 54. As a result, the excessive torque does not act on the worm gear 52 or the rotation motor 51, and the worm gear 52 and the rotation motor 51 are protected.

Furthermore, when the vehicle collides with an obstacle, the rotation angle is fixed at the collision position. Therefore, the rotation angle indicated by the rotation angle detection signal D1 sent from the variable lighting device 10 to the tablet 90 is the rotation angle at the collision position. Therefore, the tablet 90 can recognize that the rotation angle is the rotation angle at the collision position, and the rotation angle displayed on the GUI control 901 (FIG. 14) for setting the rotation angle is the rotation angle at the collision position.
As a result, even if a collision occurs, the rotation angle of the luminaire 30 of the variable lighting device 10 coincides with the rotation angle of the luminaire 30 recognized by the tablet 90. Therefore, even after the collision state is resolved, the tablet 90 can normally control the rotation of the luminaire 30.

The following describes an operating state when the tablet 90 (FIG. 13) sends a head-oscillating control signal C2 to the variable lighting device 10 and the lighting device 30 collides with an obstacle or the like while it is oscillating, making it unable to perform the head-oscillating operation.
In this case, excessive torque exceeding the second specified torque is applied from the lamp 30 to the oscillation motor 61 of the second drive unit 60 (FIG. 11), causing slippage between the wave washer 65 (not shown) and the worm wheel 62b and between the wave washer 65 (not shown) and the nut 64. As a result, the excessive torque does not act on the worm gear 62 or the oscillation motor 61, and the worm gear 62 and the oscillation motor 61 are protected.

Furthermore, when the robot collides with an obstacle, the oscillation angle is fixed at the collision position. Therefore, the oscillation angle indicated by the oscillation angle detection signal D2 sent from the variable lighting device 10 to the tablet 90 is the oscillation angle at the collision position. Therefore, the tablet 90 can recognize that the oscillation angle is the oscillation angle at the collision position, and the oscillation angle displayed on the GUI control 902 (FIG. 14) for setting the oscillation angle is the oscillation angle at the collision position.
As a result, even if a collision occurs, the oscillation angle of the luminaire 30 of the variable lighting device 10 coincides with the oscillation angle of the luminaire 30 recognized by the tablet 90. Therefore, even after the collision state is resolved, the oscillating control operation of the luminaire 30 by the tablet 90 can be performed normally.

[Explanation of the operating state when the operator manually adjusts the attitude of the lamp]
This section describes the operating state when an operator manually adjusts the attitude of the lamp 30 by applying force while holding the lamp 30 in his/her hand in order to preset the attitude (rotation angle and swivel angle) of the lamp 30 and direct the light emitted from the lamp 30 to a predetermined target position on the irradiated body.

The operator first sends a light on/off control signal C4, which contains information indicating that the light should be turned on, from the tablet 90 to the variable lighting device 10 to turn on the light source 36 and cause the luminaire 30 to emit light.

Next, the operator manually moves the lamp 30 in the rotation direction and the tilt direction to manually adjust the attitude of the lamp 30 so that the emitted light strikes a predetermined target position on the illuminated object.
When the lamp 30 is manually moved in the turning direction, an excessive torque exceeding the first specified torque is applied to the first drive unit 50 (FIGS. 7 and 8), but slippage occurs in the first drive unit 50, allowing the lamp 30 to move in the turning direction. At this time, since slippage occurs in the first drive unit 50, the worm gear 52 and the turning motor 51 are protected.
When the lamp 30 is manually moved in the oscillation direction, an excessive torque exceeding the second specified torque is applied to the second drive unit 60 (FIG. 11), but slippage occurs in the second drive unit 60, allowing the lamp 30 to move in the oscillation direction. At this time, since slippage occurs in the second drive unit 60, the worm gear 62 and the oscillation motor 61 are protected.

When the lamp 30 is manually moved in the rotation direction, the rotation angle indicated by the rotation angle detection signal D1 sent from the variable lighting device 10 to the tablet 90 changes in accordance with the rotation movement of the lamp 30. When the lamp 30 is manually moved in the oscillation direction, the oscillation angle indicated by the oscillation angle detection signal D2 sent from the variable lighting device 10 to the tablet 90 changes in accordance with the oscillation movement of the lamp 30.
As a result, even if the lamp 30 is manually moved in the rotation direction or the oscillation direction, the rotation angle and oscillation angle of the lamp 30 of the variable lighting device 10 match the oscillation angle and rotation angle of the lamp 30 recognized by the tablet 90. Therefore, even after the attitude of the lamp 30 is manually adjusted, the rotation control operation and the oscillation control operation of the lamp 30 by the tablet 90 can be performed normally.

[Modification]
In the embodiment shown in FIG. 1, a plurality of variable lighting devices are installed. However, the present invention is not limited to this. A single variable lighting device may be controlled by a single tablet (remote control terminal).

Furthermore, in the above-mentioned embodiment, it has been described that in addition to the irradiation direction, dimming, color adjustment, and light distribution angle can also be controlled, but this is not limited thereto, and it is sufficient if at least the irradiation direction can be controlled.

In the above embodiment, the scene registration and angle registration are stored in each variable lighting device, and when a predetermined timer time has elapsed, a control signal is output from the remote control terminal (tablet), and this is used as a key to operate each variable lighting device to enter the state indicated in the scene registration and angle registration, but this is not limited to the above. For example, it is also possible to have a configuration in which the scene registration and angle registration are not stored in each variable lighting device by including information on the scene registration and angle registration of each variable lighting device in the control signal output from the remote control terminal (tablet) when a predetermined timer time has elapsed.

Furthermore, in the above-described embodiment, the combination of the configuration in which the remote control terminal (tablet) has a timer function and the configuration in which multiple variable lighting devices form a mesh network makes it possible to precisely control all of the variable lighting devices in conjunction with each other, but this is not limited to this. For example, instead of the configuration in which the remote control terminal (tablet) has a timer function, it is also possible to adopt a configuration in which one of the multiple variable lighting devices has a timer function, or a configuration in which each variable lighting device has a timer function.
