In addition, the basic control display 112 displays a list of all the functions of the lighting fixture 30 such as a zoom function, a strobe function, and a light output curve that can be arbitrarily controlled.

The operation display 113 displays the type of operation to be performed for each channel out of the plurality of channels displayed in the appliance channel display 116 . For example, when the luminescence colors (hereinafter referred to as mixed-color light) output by the plurality of light-emitting elements 311 of a plurality of colors are created in one of the virtual control channels of the lighting fixture 30 , which Select whether to set the desired mixed color light for the channel, and select the Mix Color button for creating the mixed color light from the operation display 113 .

Then, a luminescent color preview 117 is displayed on the display section 11 (41), and an arbitrary color can be selected. The luminous color preview 117 is a color preview representing a color close to the actual luminous color, and the ratio of each color of the light emitting elements 311 constituting the luminous colors such as R (Red), G (Green), B (Blue) and the total color. It displays a luminance ratio, a color map in which the horizontal axis represents chromaticity and the vertical axis represents saturation, and the like.

When an arbitrary color is determined by the luminescent color preview 117, the ratio of each color of the light emitting elements 311 constituting the luminescent color of the determined color and the ratio of the overall luminance are set in the selected virtual control channel and displayed in the fixture channel display 116. At the same time, the control channel of the corresponding lighting device 30 is also stored in the storage unit 32 with the light emission color information, which is the ratio of each color of each light emitting element 311 and the ratio of the overall luminance determined.

The operation display 113 has, for example, a Delete button, an Insert button, and an Erase button in addition to a Mix Color button for setting arbitrary mixed color light.

The Delete button deletes the information set for one channel of the selected fixture channel display 116 (Mix Color information set for channel 4 of the fixture channel display 116 in FIG. 5) and clears the information for the corresponding channel. return.

The Insert button inserts a new configurable blank into one of the selected fixture channel displays 116 (in FIG. 5 inserts a new blank into channel 4 of the fixture channel display 116 and sets it to original channel 4). The original Mix Color information is set to channel 5, the original Mix Color information set to channel 5 is set to channel 6, and the original Mix Color information set to channel 6 is set to be set to channel 7. displayed).

The Erase button deletes the information set in one channel of the selected fixture channel display 116, and moves up and displays the channels below the corresponding channel one by one (in FIG. 5, channel 4 of the fixture channel display 116 is selected). When the Erase button is selected, the Mix Color information set in the original channel 4 is deleted, the original channel 5 Mix Color is set in the channel 4, and the original channel 6 Mix Color is set in the channel 5).

The overall operation display 114 has, for example, an All Copy button and an All Delete button.

The All Copy button, when selected and determined, copies all lighting condition information 321 including luminescent color information displayed on the fixture channel display 116 of a certain lighting fixture 30 connected to the light control console 10a or the external terminal 40. The copied lighting condition information 321 can be further stored in the storage unit 32 of the same lighting device 30, or the copied lighting condition information 321 can be stored in the storage unit 32 of another lighting device 30 as it is.

The name display section 115 displays the name or number of each lighting device 30 arbitrarily set by the operator. The set name may include Japanese, alphanumeric characters, and other symbols.

With these configurations, even when a plurality of lighting fixtures 30 are used, it is possible to copy arbitrarily set lighting condition information 321 as it is and set it to a large number of lighting fixtures 30 . In addition, since the lighting device 30 stores arbitrary light emission color information in the storage unit 32 as one piece of information assigned to each control channel, even if the lighting device 30 is connected to the light control console 10b that does not have a light emission color setting function, By assigning an arbitrary corresponding control channel to the output operation unit 14, it is possible to easily irradiate the desired mixed color light from the lighting device 30. FIG. In addition, since it is possible to operate the output level value using the input from the output operation unit 14 as the master value without changing the ratio of each light color that constitutes the set arbitrary mixed light, the output level value can be reproduced by a plurality of light colors. It is possible to easily perform the output operation of the emitted light colors with a smaller number of output operation units 14 . In addition, since it is possible to store information on mixed light with an arbitrary light color ratio as light emission color information in a plurality of lighting fixtures 30, if a plurality of frequently used mixed lights are stored in the storage unit 32, A desired emission color can be easily obtained.

Further, when the lighting fixture 30 is connected to the light control console 10a (or the external terminal 40) via the communication line, the lighting condition information 321 including the individual fixture ID and the luminescent color information of the connected lighting fixture 30 is is transmitted to the control unit 12 (42) of the light control console 10a (or the external terminal 40). The control unit 12 (42) of the lighting control console 10a (or the external terminal 40) that has received the transmitted lighting condition information 321 arbitrarily calls all or part of the lighting condition information 321 to the display unit 11 (41). can be displayed. At this time, the lighting condition information 321 may be empty information in which no information is set. A remaining frame indicating how much information corresponding to the remaining control channels can be set in the storage unit 32 of the corresponding lighting device 30 is displayed.

Further, when an operation such as changing, adding, or deleting the displayed lighting condition information 321 is performed from the light control console 10a (or the external terminal 40), a corresponding operation signal is transmitted to the corresponding lighting fixture 30, and the storage unit 32 The lighting condition information 321 inside is changed, added, or deleted.

Since the lighting device 30 can store the lighting condition information 321 including the light emission color information, it is possible to easily change the light emission color, irradiation angle, and light emission according to the target scene even when the lighting device 30 is moved to another studio or the like. It is possible to perform lighting control, which is an output.
(Emitting color setting)

A mechanism for setting the color of light emitted from the lighting fixture 30 in the lighting system according to the embodiment of the present invention will be described with reference to FIG.

In FIG. 6, the light control console 10a or the external terminal 40 has a plurality of output operation units 14 assigned to control channel 1 (CH1) to control channel n (CHn), respectively.

The output operation unit 14 can set any output level value 1 to output level value n between 0% and 100% by the operation of the operator. Arbitrary percentages set for the output level value 1 to the output level value n are set to x1% to xn%, respectively.

Further, in the storage unit 32 of at least one or more lighting fixtures 30 connected to the light control console 10a or the external terminal 40, the stored luminescent color information 1 to luminescent color information n are stored in the control channel 1 to control channel n, respectively. Assume it is assigned and set.

Further, the emission color information 1 to n each store the ratio of R, G, and B, which are the light colors constituting the emission color. R1%, G1%, and B1% are set, and if the emission color information is n, Rn%, Gn%, and Bn% are set.

In this case, when an attempt is made to output the luminescent color of the luminescent color information 1 by operating the output operation unit 14 assigned to the control channel 1, the lighting device 30 having the luminescent color information 1 stored in the storage unit 32 is turned on. The control unit 33 multiplies the output level value 1 input from the output operation unit 14 by the ratio of each light color in the emission color information 1, and obtains light color R as R1×1%, light color G as G1×1%, and light color B. is output at a rate of B1×1%.

Similarly, the output level values 2 to n of the output operation unit 14 assigned to the control channels 2 to n are multiplied by the light color ratios of the emission color information 2 to n assigned to the control channels 2 to n, respectively. The lighting fixture 30 corresponding to channel 2 has a light color R of R2x2%, a light color G of G2x2%, and a light color B of B2x2%. Emission colors are output at a ratio of Gnxn% for color G and Bnxn% for light color B. Note that the types and number of light colors exemplified here are arbitrary, and other light colors such as amber may be provided instead of R, G, and B colors, and the number of types of light colors is more than three. At least good.

Next, how to set the emission color when a plurality of control channels are assigned to the same lighting fixture 30 and the output operation units 14 assigned to the plurality of control channels are simultaneously operated, as shown in parentheses with dotted lines in FIG. explain how

For example, it is assumed that the same lighting device 30 stores luminescent color information 1 to n assigned to control channels 1 to n. When this lighting device 30 is simultaneously operated by a plurality of output operation units 14 assigned to control channels 1 to n, corresponding light color ratios R1x1 to Rnxn%, G1x1 to Gnxn% and B1x1 to Bnxn% are calculated. The lighting control unit 33 extracts the ratio of the highest output value for each light color among these light color ratios. For example, in FIG. 6, control channel 1 has the highest output ratio of light color R among control channels 1 to n, and control channel 1 has the highest output ratio of light color G. G1x1%, the highest output ratio of light color B is Bnxn% of control channel n. At this time, the lighting fixture 30 is controlled to emit light of R, G, and B at output ratios of R1x1%, G1x1%, and Bnxn%, respectively.

As a result, even if mixed light with different light color ratios is set for a plurality of control channels assigned to the same lighting device 30, the plurality of output operation units 14 corresponding to the plurality of control channels can be intuitively operated. Arbitrary mixed colors and emitted colors can be obtained.
