Description

  The present invention relates to a dimming controller for dimming control of an illumination load used in a stage, a theater, a banquet hall, a hall, and the like.

  Conventionally, a dimmer that adjusts the power supplied to the lighting load is used in a stage, a theater, a banquet hall, a hall, and the like. The dimming device adjusts the power supplied to the lighting load based on the dimming signal given from the dimming controller, and dimming-controls the lighting load by supplying the adjusted power to the lighting load.

  The dimming controller that outputs a dimming signal to the dimming device has a plurality of slide-type faders, and the brightness of the illumination load, that is, the dimming level can be controlled by operating each fader. . Faders include preset faders (also referred to as “channel faders”) that set the dimming level in units of lighting loads called channels. That is, the preset fader is associated with each channel, and the illumination load of each channel is lit at a dimming level determined according to the operation value of the corresponding preset fader.

  Furthermore, in order to cope with diversified lighting effects in recent years, it is common to store in advance as a scene the lighting load states of a plurality of channels created by operating a plurality of preset faders. As a result, if a desired scene is designated and reproduced from a plurality of preset scenes, the illumination load of the plurality of channels is determined according to the operation values of the plurality of preset faders at the time of storing the designated scene. Lights at light level.

  In order to cope with this scene reproduction, a dimming controller having a sub master fader as a fader in addition to a preset fader has been proposed (see, for example, Patent Document 1). The sub master fader is associated with each scene stored in advance, and each scene is reproduced at a reproduction level determined according to the operation value of the corresponding sub master fader. Therefore, not only can the brightness for reproducing each scene be arbitrarily adjusted, but also a plurality of scenes can be reproduced by being operated by operating a plurality of sub-master faders.

  However, the two types of faders such as the preset fader and the sub-master fader described above are associated with a plurality of channels and a plurality of scenes, respectively, so that the occupied space increases as the number of channels and the number of scenes increase. Therefore, when the dimming controller has a preset fader and a sub-master fader separately, it is necessary to reduce the number of channels and scenes to reduce the size of the dimming controller. There is a problem that the function is sacrificed.

  Therefore, it is conceivable to provide a selector switch that can switch the function of the fader between a function as a preset fader and a function as a sub master fader. As a result, the same fader can be used as both the preset fader and the sub-master fader, and the space occupied by the fader can be reduced and the dimming controller can be downsized without reducing the number of channels and scenes. Is possible.

Japanese Patent No. 2638018

  However, in the dimming controller having the above-described configuration, the function of the fader may be switched unintentionally by the user because the user's hand unexpectedly hits the changeover switch. Further, since the fader operation value immediately after the fader function is switched becomes the fader operation value immediately before switching, light may be emitted from an unintended lighting load immediately after the fader function is switched. As a result, there is a problem that the operability is deteriorated by making the function of the fader switchable.

  The present invention has been made in view of the above-described reasons, and an object thereof is to provide a dimming operation device that is improved in operability while achieving downsizing by enabling the function of a fader to be switched.

  According to the first aspect of the present invention, a dimming signal for dimming and controlling the lighting load is output to each of the dimming devices that dimming and controlling the plurality of lighting loads divided into the plurality of channels. Preset unit that determines the dimming level that controls the brightness of the lighting load according to the operation values set by the fader for each channel, and a plurality of faders that can be operated individually, and presets Depending on the product of the scene storage unit that stores the combination of dimming levels of multiple channels output from the unit as a scene, and the operation value set by the fader for each scene and the dimming level stored in the scene storage unit A scene playback unit that determines the light control level, a preset mode that uses the fader output in the preset unit, and a scene playback mode that uses the fader output in the scene playback unit. Switching means for switching between two operation modes, and the switching means further has a changeover switch for changing over the operation mode, and when the changeover switch is operated, the output to the preset unit and the scene playback unit is output to the fader Regardless of whether the changeover switch is in a transitional state that is maintained at the time of operation, the first time when all faders are lowered to the minimum value of the movable range in the transient state, and the fader is operated after the first time The operation mode is switched at any time point with the second time point.

  According to this configuration, the function of the fader can be switched by switching the operation mode with the switching means, and the space occupied by the fader can be reduced to achieve miniaturization. In addition, when the changeover switch is operated, the changeover means shifts to a transient state in which the output to the preset unit and the scene reproduction unit is maintained at the operation state of the changeover switch regardless of the fader output. The operation mode is not switched only by being operated, and the illumination load is maintained in the state immediately before the operation of the changeover switch. Further, since the switching means switches the operation mode only after all faders are lowered to the minimum value of the movable range in the transient state, the operation value of the fader immediately after the switching of the operation mode becomes zero. Therefore, light is not emitted from an illumination load unintended by the user immediately after the function of the fader is switched. As a result, there is an advantage that operability is improved while the function of the fader can be switched.

  The invention of claim 2 is characterized in that, in the invention of claim 1, the switching means has a display unit for displaying whether the preset mode and the scene reproduction mode are in the transient state.

  According to this configuration, the user can operate the fader after confirming whether the preset mode and the scene playback mode are in a transitional state, thereby eliminating an error in operating the fader due to misunderstanding of the operation mode. Can do.

  According to a third aspect of the present invention, in the first or second aspect of the invention, the switching means switches the operation mode at the second time point when switching from the scene playback mode to the preset mode, and the second time point. The output to the scene reproduction unit is gradually reduced as the fader is raised.

  According to this configuration, since the lighting state of the lighting load in the scene playback mode and the lighting state of the lighting load in the preset mode are switched gradually, the lighting state of the lighting load is smoothly changed before and after the operation mode switching. Can be changed.

  According to the present invention, by providing the switching means, the function of the fader can be switched and the size can be reduced. Further, the switching means has an advantage that the operability is improved because the operation mode is switched only when all the faders are lowered to the minimum value of the movable range in the transient state.

(Embodiment 1)
In the present embodiment, the dimming controller of the present invention will be described by taking as an example a dimming controller 1 used in a dimming system in which a plurality of illumination loads 2 are subject to dimming control as shown in FIG.

  The dimming system of FIG. 2 includes a dimming controller 1 that outputs a dimming signal for instructing a dimming level, and a dimming panel 30 having a plurality of dimming devices 3. Each dimming device 3 individually receives a dimming signal from the dimming controller 1 and performs dimming control on the target illumination load 2 so as to be lit at the dimming level represented by the dimming signal. To do.

  The dimmer 3 includes a dimmer circuit (not shown) that includes a switching element and performs phase control of a load current supplied from an AC power source (not shown) to the illumination load 2, A dimming control unit (not shown) that receives the dimming signal and controls the dimming circuit. The switching element is inserted into a power supply path from the AC power source to the lighting load 2 and is conducted between an arbitrary phase angle of the AC current supplied from the AC power source and the zero cross point. The dimming control unit adjusts the amount of electric power supplied to the lighting load 2 per unit time by changing the phase angle of the switching element in accordance with the dimming signal from the dimming controller 1. Dimming control is performed.

  The dimming controller 1 transmits a dimming signal including a DMX signal to each dimming device 3 of the dimming panel 30 in response to an operation input from the user. The DMX signal is a signal that can transmit data of 512 channels at the maximum and is provided with data of 256 levels of dimming levels for each channel.

  By the way, the dimming controller 1 has a plurality of slide type faders 10 (see FIG. 1). When each fader 10 is operated, the brightness of the illumination load 2, that is, the dimming level is determined by the operation value. Can be operated. The operating value of fader 10 varies continuously between 0 and 100%.

  The fader 10 has two types of functions: a preset fader that sets a dimming level in units of groups of illumination loads 2 called channels, and a sub-master fader described later. The preset faders are associated with each channel, and the illumination load 2 of each channel is lit at a dimming level determined according to the operation value of the corresponding preset fader.

  As shown in FIG. 3, the dimming controller 1 includes a preset unit 11 that determines a dimming level according to an operation value set by a preset fader for each channel, and a dimming level for the dimming device 3. And an output unit 12 that outputs a dimming signal. Although only one fader 10 is shown in FIG. 3, it is assumed that a plurality of faders 10 are actually provided.

  The dimming controller 1 includes a scene storage unit 13 that stores a combination of dimming levels of a plurality of channels output from the preset unit 11 as a scene. Further, the dimming controller 1 includes a scene reproduction unit 14 that determines the dimming level according to the product of the operation value set by the sub master fader for each scene and the dimming level stored in the scene storage unit 13. It has.

  The scene storage unit 13 is configured to be able to store a plurality of scenes respectively corresponding to a plurality of storage buttons B1 to Bn (see FIG. 1) provided on the dimming controller 1. The scene reproduction unit 14 determines the dimming level according to the product of the operation value set by the sub master fader for each scene and the dimming level stored in the scene storage unit 13. That is, the sub master faders are associated with each scene, and each scene is reproduced at a reproduction level determined according to the operation value of the corresponding sub master fader.

  In short, the dimming controller 1 can previously store the state of the illumination loads 2 of a plurality of channels created by operating a plurality of preset faders as a scene. If a desired scene is designated and reproduced from a plurality of preset scenes, the lighting load 2 of the plurality of channels is dimmed according to the operation values of the plurality of preset faders at the time of storing the designated scene. Lights at level.

  Here, the dimming controller 1 of the present embodiment reproduces a plurality of scenes by superimposing them, and the highest value is the product of the reproduction level corresponding to the scene being reproduced and the dimming level for each channel. Highest calculation is adopted so that the dimming level of the illumination load 2 of each channel is obtained. Therefore, not only can the brightness for reproducing each scene be arbitrarily adjusted, but also a plurality of scenes can be reproduced by being operated by operating a plurality of sub-master faders.

  Hereinafter, the highest calculation will be described. Table 1 below shows combinations of dimming levels for all channels (CH1 to CH9) for each of scene 1 and scene 2, and these combinations of dimming levels are “scene 1” and “scene 2”, respectively. Indicates that it is stored. Table 2 below shows the result of the highest calculation (that is, the dimming level of each channel) when both the scene 1 and the scene 2 are simultaneously reproduced with the reproduction level = 100%.

ここでは一例として、「シーン１」は、舞台上に組まれたセットを照らす目的で、舞台上のセット（ここでは喫茶店の店内を表すセットとする）に合わせて各チャンネルの調光レベルが設定された、ベースとなる照明パターンを実現するものとする。つまり、シーン１では、たとえば窓際の席を照明するチャンネルの調光レベルを高く設定し、窓から少し離れた席を照明するチャンネルの調光レベルを低めに設定するなどして、喫茶店の店内の雰囲気を再現する。

Here, as an example, “Scene 1” sets the dimming level of each channel according to the set on the stage (here, the set representing the inside of the coffee shop) for the purpose of illuminating the set assembled on the stage. It is assumed that the base illumination pattern is realized. In other words, in scene 1, for example, the dimming level of the channel that illuminates the seat at the window is set high, and the dimming level of the channel that illuminates the seat slightly away from the window is set low. Reproduce the atmosphere.

  On the other hand, “scene 2” realizes an additional illumination pattern in which the dimming level of each channel is set in accordance with the standing position of the person on the stage for the purpose of illuminating the person. In other words, in scene 2, for example, the dimming level of the channel that illuminates the standing position of the leading role on the stage is set high, and the dimming level of the channel that illuminates the standing position of the supporting role is set low. Can stand out.

  In this example, since both the scene 1 and the scene 2 have the playback level = 100%, the product of the playback level and the light control level corresponding to the scene being played back is the light control level of each of the scenes 1 and 2. It becomes the same value. Therefore, when a highest calculation is performed for these scenes 1 and 2, the lighting load 2 of each channel is dimmed and controlled using the higher dimming level of scenes 1 and 2 as shown in Table 2. . Eventually, in addition to brightly illuminating the seat at the window by the channel that illuminates the seat at the window, the leading role is illuminated by the channel that illuminates the standing position of the leading role.

  After that, if only the standing position of the person changes without changing the set assembled on the stage, the scene 1 is left as it is, and only the scene 2 is changed to the scene 3 set to another standing position. Thus, scene 1 and scene 3 may be reproduced simultaneously. Thereby, since the scene 1 is reproduced as it is, it is possible to avoid a sudden change in the atmosphere of the coffee shop.

  As described above, by performing the highest calculation, the dimming level of each channel can be set according to the purpose of each scene, and the lighting pattern can be suddenly changed by changing only one of the scenes. There is an advantage that it is possible to prevent a change.

  Further, here, as an example, the case where the scene 1 is used as a base and the scene 2 is additionally used has been described, but the highest operation is not limited to such usage. That is, for example, when 10 scenes are stored, only 10 types of illumination patterns can be realized only by reproducing each scene individually. On the other hand, if the highest operation is used, the number of illumination patterns that can be realized by a combination of a plurality of scenes is greatly increased.

  By the way, the dimming controller 1 of this embodiment is implement | achieved by switching the function of the same fader 10 to the preset fader and submaster fader which were mentioned above. That is, the dimming controller 1 includes switching means 15 for switching the function of the fader 10 between the preset fader and the sub master fader, and the same fader 10 is used as the preset fader and the sub master fader. Thereby, compared with the case where the fader 10 used as the preset fader and the fader 10 used as the sub master fader are provided separately, the space occupied by the fader 10 in the dimming controller 1 can be reduced, and the dimming controller 1 can be downsized. Can be achieved.

  The switching unit 15 switches between two operation modes: a preset mode in which the operation value output from the fader 10 is input to the preset unit 11 and a scene playback mode input to the scene playback unit 14. Thereby, the fader 10 functions as a preset fader in the preset mode, and functions as a sub-master fader in the scene reproduction mode.

  Therefore, in the preset mode, the preset unit 11 receives the operation value of the fader 10 and outputs a dimming level to the output unit 12 according to the operation value of the fader 10 for each channel. The output unit 12 generates a dimming signal having a dimming level received from the preset unit 11 and outputs the dimming signal to the dimming device 3. In the preset mode, when any one of the storage buttons B1 to Bn is operated, the scene storage unit 13 determines the combination of the dimming levels at the time of operation of the storage buttons B1 to Bn. Store as a scene corresponding to Bn.

  On the other hand, in the scene playback mode, the scene playback unit 14 receives the operation value of the fader 10, determines a playback level according to the operation value of the fader 10 for each scene, and stores the playback level and the scene storage unit 13. The product of the light control level is output to the output unit 12 as the light control level. The output unit 12 generates a dimming signal having a dimming level (product of the reproduction level and the dimming level) received from the scene reproducing unit 14 and outputs the dimming signal to the dimming device 3.

  More specifically, the switching unit 15 temporarily stores a changeover switch SW that accepts an operation mode switching operation from the user, a switching processing unit 16 that switches the operation mode by the operation of the changeover switch SW, and an operation value of the fader 10. And an operation value storage unit 17. The change-over switch SW includes a first change-over switch SW1 (see FIG. 1) for changing to the preset mode and a second change-over switch SW2 (see FIG. 1) for changing to the scene reproduction mode. Is simply referred to as a changeover switch SW.

  When the changeover switch SW is operated, the change processing unit 16 stores the operation value of the fader 10 at the time of operation of the changeover switch SW as a stored value in the operation value storage unit 17 and determines the dimming level based on the stored value. Transition to a transient state.

  That is, in the transient state, both the preset unit 11 and the scene playback unit 14 are disconnected from the fader 10, and the dimming level is determined by using the stored value as the operation value regardless of the actual operation of the fader 10. . Therefore, in the transient state, the output to the preset unit 11 and the scene reproduction unit 14 is maintained at the state when the changeover switch SW is operated.

  The switching processing unit 16 switches the operation mode at the time point (first time point) when all the faders 10 are lowered to the minimum value (here, 0%) of the movable range in the transient state. For this reason, even if the changeover switch SW is operated, the switching means 15 does not immediately switch the operation mode, but first shifts to a transient state, and only when all the faders 10 are operated in this transient state becomes 0%. Switch the operation mode. When the changeover switch SW for returning to the original operation mode is operated in the transient state, the transition state is exited and the original operation mode is restored.

  Further, the switching unit 15 has a function as a display unit that displays different operation modes (preset mode / scene reproduction mode). In the present embodiment, by using a light emitting switch as the changeover switch SW, the changeover switch SW is also used as a display unit. That is, in the preset mode, the first changeover switch SW1 is turned on, and in the scene reproduction mode, the second changeover switch SW2 is turned on to display the different operation modes.

  Further, the display unit displays whether or not the switch is in a transient state by blinking the switches SW1 and SW2 in the transient state and continuously lighting the switch switches SW1 and SW2 in other than the transient state. As a result, the user can confirm both the operation mode and the transitional state.

  Hereinafter, the operation of the dimming controller 1 having the above-described configuration will be briefly described with reference to FIG. In FIG. 1, the fact that the change-over switch SW is turned off is outlined, the continuous lighting is black, and the blinking is indicated by hatching.

  First, in the preset mode, as shown in FIG. 1A, the first changeover switch SW1 is continuously lit, and the fader 10 functions as a preset fader. In this state, since each fader 10 is associated with each channel, if the fader 10 is operated, the dimming level of the corresponding channel changes. In the example of FIG. 1A, the operation value of the fader 10 corresponding to the channel CH1 is adjusted to 75%, and all the faders 10 other than the channel CH1 are adjusted to 0%, and the output unit 12 outputs the illumination load 2 of the channel CH1. A dimming signal is output to turn on only at a dimming level of 75%.

  When the second changeover switch SW2 for switching to the scene playback mode is pressed in the state of FIG. 1A, the switching means 15 shifts to a transient state, so that the second changeover switch SW2 as shown in FIG. 1 switch SW1 is blinked to indicate that it is in a transient state. In this state, regardless of the actual operation value of the fader 10, the dimming level is determined by the stored value (the operation value of the fader 10 at the time of operation of the changeover switch SW2) stored in the operation value storage unit 17. Therefore, the output unit 12 continuously outputs a dimming signal similar to that before the operation of the changeover switch SW2, regardless of the operation value of the fader 10.

  When all the faders 10 are lowered to 0% in the transient state of FIG. 1B, the switching means 15 completes the switching to the scene reproduction mode, and the second changeover switch as shown in FIG. SW2 is turned on to indicate that it is in the scene playback mode. In this state, since each fader 10 is associated with each scene, if the fader 10 is operated, the playback level of the corresponding scene changes. For example, when the operation value of fader 10 corresponding to scene S1 is adjusted to 75% and all faders other than scene S1 are adjusted to 0%, scene reproducing unit 14 reproduces only scene S1 at a reproduction level of 75%. Thereby, the output unit 12 outputs a dimming signal that turns on the illumination load 2 at a dimming level obtained by multiplying the combination of dimming levels for a plurality of channels stored as the scene S1 by 75%. .

  In the scene playback mode, when the first changeover switch SW1 for switching to the preset mode is pressed, the changeover means 15 shifts to a transient state, so that the second changeover switch SW2 as shown in FIG. 1 (d). Blinks to indicate that it is in a transient state. In this state, regardless of the actual operation value of the fader 10, the dimming level is determined by the stored value (the operation value of the fader 10 at the time of operation of the changeover switch SW1) stored in the operation value storage unit 17. Therefore, the output unit 12 continuously outputs a dimming signal similar to that before the operation of the changeover switch SW1 regardless of the operation value of the fader 10.

  In the dimming controller 1 having the above-described configuration, the switching unit 15 does not switch the operation mode only by operating the changeover switch SW, but first shifts to a transient state, and all the faders 10 operate in this transient state. The operation mode is not changed until it becomes 0%. Therefore, even if the user's hand unexpectedly hits the changeover switch SW, it is possible to avoid the function of the fader 10 being switched without the intention of the user.

  Moreover, the operation values of the fader 10 immediately after the function of the fader 10 is switched are all 0%, and do not depend on the operation value of the fader 10 immediately before switching. For example, in the preset mode, even when the changeover switch SW2 is operated with the operation value of the fader 10 corresponding to the channel CH1 being 75%, all the faders 10 are lowered to 0% when switching to the scene reproduction mode. Become. Therefore, it is possible to avoid a situation where light is emitted from the illumination load 2 that is not intended by the user immediately after the fader 10 is switched. As a result, the operability of the dimming controller 1 is improved while the dimming controller 1 can be reduced in size by switching the function of the fader 10.

(Embodiment 2)
The dimming controller 1 of this embodiment has a cross-change function in which the switching unit 15 gradually decreases the output of the stored value as the fader 10 rises from 0% when the switching of the operation mode is completed. Is different from the dimming controller 1 of the first embodiment.

  In this embodiment, the switching processing unit 16 does not switch the operation mode when all the faders 10 are lowered to 0% in the transient state (first time point), and any one of the faders 10 is operated thereafter. The operation mode is switched at the time (second time). Here, the cross change function is activated by operating the fader 10 while pressing the shift switch SW0 (see FIG. 1) provided above the changeover switch SW. That is, whether or not to use the cross change function can be selected based on the judgment of the user.

  First, the operation of the dimming controller 1 when the cross change function is not used will be described. In this case, in a transient state after the changeover switch SW is operated, when any one of the faders 10 is raised after all the faders 10 are lowered to 0%, the output of the stored value is stopped. For this reason, when the operation mode is switched from the transient state, the illumination load 2 is completely turned off for a moment.

  Next, the operation of the dimming controller 1 when the cross change function is used will be described with reference to FIG. FIG. 4 shows the operation when the scene playback mode is switched to the preset mode by operating the first changeover switch. The horizontal axis represents the time axis, and the vertical axis represents the outputs of the preset unit 11 and the scene playback unit 14. In FIG. 4, the solid line indicates the output from the switching unit 15 to the preset unit 11, and the two-dot chain line indicates the output from the switching unit 15 to the scene reproduction unit 14.

  When the first changeover switch SW1 is pressed during the scene playback mode, the dimming level is separated from the actual operation value of the fader 10, and is determined by the operation value (stored value) immediately before the changeover switch SW1 is operated. Is done. Therefore, even at the time t1 when all the faders 10 are lowered to 0%, the output (reproduction level) to the scene reproduction unit 14 is maintained by the stored value (t1 to t2). At this time, the output (dimming level) to the preset unit 11 is 0%.

  When the user raises one of the faders 10 while pressing the shift switch SW0 at time t2, the operation mode is switched to the preset mode, and thereafter, the output to the preset unit 11 increases as the fader 10 rises ( t2-t3). However, due to the cross change function, the output to the scene reproduction unit 14 does not suddenly become 0% but gradually decreases as the fader 10 rises. Here, the output to the scene playback unit 14 is set to 0% when the fader 10 is raised to 100%.

  When the operation value of the fader 10 reaches 100% at time t3, the preset mode is completely switched and the output to the scene reproduction unit 14 becomes 0%. Therefore, after time t3, the fader 10 functions as a preset fader, and the operation value of the fader 10 is completely disconnected from the scene reproduction unit 14 (t3 to t4).

  As described above, by using the cross change function, the lighting state of the lighting load 2 in the scene reproduction mode and the lighting state of the lighting load 2 in the preset mode are gradually switched. This cross-change function is used to smoothly change the lighting state of the illumination load 2 before and after switching when the operation mode switching is completed.

  Although FIG. 4 illustrates the operation at the time of switching from the scene playback mode to the preset mode, the cross change function can be similarly used when switching from the preset mode to the scene playback mode.

  Other configurations and functions are the same as those of the first embodiment.
