Description

  Embodiments described herein relate generally to a lighting device and a lighting fixture setting method.

  Conventionally, various lighting effects are made in a studio, a stage, and the like by a plurality of lighting devices. In lighting control systems using lighting equipment such as halogen lamps, when performing similar lighting effects in multiple studios and stages, etc., if the same color filter as the transition source is attached to each lighting equipment of the transition destination, The lighting effect can be reproduced simply by performing the same operation as the source.

  On the other hand, the introduction of lighting equipment that can control color, such as LED (Light Emitting Diode) lighting, is progressing. However, in lighting control systems that control such lighting equipment, control signals at exactly the same level are sent to the same model. However, it is often seen that the exact same color does not appear. When exactly the same color does not appear, it is necessary to finely adjust the level of the control signal to RGB with a single lighting device, and therefore it takes a long time for adjustment.

In other words, the lighting device 10-1 corrects the light output characteristic unique to the lighting device 10-1 to the light output characteristic corresponding to the reference characteristic.

  For example, as illustrated in FIG. 3A, the lighting device 10-1 has a light output characteristic of performing Y1 light output when an X1 output instruction signal is transmitted as a red light output instruction. ing. In this case, the illumination device 10-1 of the embodiment corrects the light output amount so as to perform the light output of the reference value Y2. The converted value in this case is a value for correcting Y1 to Y2. For the lighting device 10-1, a converted value is calculated for each output instruction signal (for each signal value) for red light.

  Further, for example, as illustrated in FIG. 3C, the lighting device 10-1 has a light output characteristic of performing Y5 light output when an X3 output instruction signal is transmitted as a blue light output instruction. Have. In this case, the lighting apparatus 10-1 of the embodiment corrects the light output amount so as to perform the light output of the reference value Y6. The converted value in this case is a value for correcting Y5 to Y6. For the lighting device 10-1, a converted value is calculated for each output instruction signal (each signal value) for blue light.

  Further, for example, as illustrated in FIG. 3D, the lighting device 10-1 outputs light having a lightness of Y10 when an output instruction signal of X10 is transmitted as a lightness light output instruction. It has light output characteristics. In this case, the illumination device 10-1 of the embodiment corrects the lightness (brightness) of light so as to perform the light output of Y11 that is the reference value. The converted value in this case is a value for correcting Y10 to Y11. For the lighting device 10-1, a converted value is calculated for each output instruction signal (each signal value) for light. Thus, the conversion value corrects the light output characteristic of the light output according to the output instruction signal specified at a predetermined time such as when the lighting device 10-1 is manufactured to the characteristic according to the output instruction signal. The value to be

  The conversion value described with reference to FIG. 3 is calculated using a predetermined calculation device (such as a computer). Specifically, the calculation device calculates a red conversion value based on the light output characteristics 101R and 102R, calculates a green conversion value based on the light output characteristics 101G and 102G, and sets the light output characteristics 101B and 102B.

[Configuration of Conversion Value Table 200 According to Embodiment]
Here, the configuration of the conversion value table 200 will be described. FIG. 4 is a diagram illustrating an example of the configuration of the conversion value table 200 according to the embodiment. The conversion value table 200 is a table in which the output instruction signal and the conversion value are associated with each other. In the converted value table 200, the output instruction signal and the converted value are associated with each of red, green, blue, and lightness.

  For example, XR1, which is a red output instruction signal, is associated with the converted value A1. Further, XG1 that is a green output instruction signal is associated with the converted value B1. Further, XB1 that is a blue output instruction signal is associated with C1 of the converted value. Further, Xx1 that is a lightness output instruction signal is associated with the converted value D1.

Is corrected, and the corrected light is output.

  When the lighting device 10-1 outputs light from the console 50 based on the output instruction signal, the lighting device 10-1 may not be able to output light in a desired color (wavelength, color temperature, etc.). This is because at least one light output amount of red, green, and blue output from the lighting device 10-1 is not a desired amount. The lighting apparatus 10-1 of the embodiment corrects at least one light output amount of red, green, and blue using the converted value, and thereby outputs light having a desired color.

  In addition, when the lighting device 10-1 outputs light from the console 50 based on the output instruction signal, the lighting device 10-1 may not be able to output light with a desired brightness. This is because the brightness of the light output from the lighting device 10-1 is not the desired brightness. The lighting device 10-1 of the embodiment corrects the lightness (brightness) of the output light using the converted value, and thereby outputs light having a desired lightness.

[Storing Procedure of Conversion Value Table 200 According to Embodiment]
Here, the flow of the storing process of the conversion value table 200 to the illumination device 10-1 according to the embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of a storage processing procedure in the illumination device 10-1 of the conversion value table 200 according to the embodiment.

  When the lighting device 10-1 is manufactured, a predetermined measuring device measures the light output characteristics of the lighting device 10-1 (step S10). The light output characteristics measured at this time are the light output amount, color, or brightness of the light output from the lighting device 10-1. For example, the lighting device 10-1 measures the light output amount and the lightness with respect to various output instruction signals. As a result, as a light output characteristic unique to the lighting apparatus 10-1, a correspondence relationship between the output instruction signal and the light output amount and a correspondence relationship between the output instruction signal and the lightness are obtained. As described above, the lighting apparatus 10-1 according to the embodiment measures the light output characteristics for each of red, green, and blue colors and the light output characteristics related to lightness.

  Moreover, the reference value of light output is preset to the illumination device 10-1. Any value can be set as the reference value. For example, a reference value for red light output, a reference value for green light output, a reference value for blue light output, and a reference value for brightness are set in the lighting device 10-1.

  Then, the predetermined calculation device calculates the converted value using the reference value (step S20). Thereby, a red conversion value, a green conversion value, a blue conversion value, and a lightness conversion value are calculated.

  Then, a conversion value table 200 in which the calculated conversion value is associated with the output instruction signal is created. The conversion value table 200 is stored in the storage unit 13 (step S30), and then the lighting device 10-1 is shipped.

[Light Output Processing Procedure of Lighting Equipment According to Embodiment]
Next, the flow of light output processing by the lighting device 10-1 according to the embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of a light output processing procedure in the lighting device 10-1 according to the embodiment.

  When the operator inputs a light output instruction to the console 50, the console 50 transmits an output instruction signal to the lighting device 10-1. This output instruction signal is a signal whose output level is designated by the operator. In other words, the output instruction signal here is an output instruction signal designated by the operator when operating the light source unit 16. When the console 50 transmits the output instruction signal, the communication unit 14 of the lighting device 10-1 receives the output instruction signal (step S110). Then, the communication unit 14 sends an output instruction signal to the control unit 15.

  The control unit 15 according to the embodiment reads the conversion value corresponding to the output instruction signal from the conversion value table 200. And the control part 15 correct | amends a light output characteristic using the read conversion value (step S120). Specifically, the control unit 15 corrects at least one of the output amount and the brightness using the converted value. The control unit 15 may correct the output instruction signal using the converted value, or may correct the light output amount and the lightness using the converted value. The control unit 15 causes the light source unit 16 to output light whose color and brightness have been adjusted by the correction (step S130).

(Conversion value table storage timing)
In the lighting device 10-1 described above, the conversion value table 200 is stored in the storage unit 13 at the time of shipment. The conversion value table 200 may be stored in the storage unit 13 after shipment. For example, after the lighting device 10-1 is connected to the baton device 20-1 and the lighting device 10-1 is connected to the console 50, the conversion value table 200 may be stored in the storage unit 13, or the conversion value The table 200 may be modified. In this case, the console 50 sends a storage instruction for the conversion value table 200 and a correction instruction for the conversion value table 200 to the lighting device 10-1. Thereby, the control part 15 of the illuminating device 10-1 performs the correction | amendment of the storage in the memory | storage part 13 of the conversion value table 200, or the conversion value table 200. FIG.

  For example, various types of lighting equipment may be connected to the lighting control system 1. In such a case, the color and brightness of the light may vary depending on the type of lighting device. In such a case, the console 50 sends a storage instruction for a new converted value table 200 and a correction instruction for the converted value table 200 to the lighting device 10-1. For example, a lighting device other than the lighting device 10-1 described in the embodiment (hereinafter referred to as other lighting devices) may be connected to the lighting control system 1. In this case, the conversion value is calculated using the color and brightness of the light output from the other lighting devices as the reference values. Then, a conversion value table 200 corresponding to the other lighting devices is generated and stored in the storage unit 13. Thereby, when the same output instruction | indication signal is sent to the illuminating device 10-1 and other illuminating devices, the illuminating device 10-1 and other illuminating devices output the light of the same color and brightness.

(Generation method of conversion value table)
When generating the conversion value table 200, the conversion value may be calculated on the assumption that the output instruction signal and the light output are in a proportional relationship. In this case, the conversion value table 200 is generated based on the output instruction signal having a predetermined magnitude and the light output corresponding to the output instruction signal. For example, the conversion value table 200 is generated based on the maximum value (100%) of the output instruction signal and the light output corresponding to the maximum value of the output instruction signal.

(First conversion method)
Moreover, although the control part 15 which concerns on embodiment correct | amended the output instruction | indication signal from the console 50 using the conversion value table 200, it correct | amends the output instruction | indication signal from the console 50 using numerical formula (conversion formula). May be. In other words, the conversion information is not limited to the conversion value table 200 in which the conversion values are stored, and may be a mathematical expression that can convert the output instruction signal into the reference value. In this case, the storage unit 13 stores the mathematical expression indicating the light output characteristics described with reference to FIG. Then, the control unit 15 corrects the light output characteristic using the mathematical formula stored in the storage unit 13.

(Second conversion method)
As described above, the lighting device 10-1 according to the embodiment stores the light output characteristic of the lighting device 10-1, the light output maximum characteristic of the lighting device 10-1, or the reference value of the light output characteristic in the storage unit 13. You may keep it. When the light output characteristic of the lighting device 10-1 and the reference value of the light output characteristic are stored in the storage unit 13, the control unit 15 uses these pieces of stored information to output an output instruction signal. Convert to the reference value. Moreover, when the light output maximum characteristic of the lighting device 10-1 and the reference value of the light output characteristic are stored in the storage unit 13, the control unit 15 outputs the information using the stored information. Convert the instruction signal to the reference value. At this time, the control unit 15 converts the output instruction signal into a reference value on the assumption that the output instruction signal and the light output are in a proportional relationship. For example, in the lighting device 10-1, the storage unit 13 stores all the light output maximum characteristics of the primary color light source, and the control unit 15 corrects any of the light output characteristics in the primary color light source to the reference value. To do. As described above, the control unit 15 corrects the light output characteristic of the lighting device 10-1 to the light output characteristic corresponding to the output instruction signal based on the reference value. And the control part 15 controls the light source part 16 using the light output characteristic after correction | amendment.

  In addition, the control part 15 may calculate the conversion value or the conversion value table 200 using the light output characteristic and light output maximum characteristic of the illuminating device 10-1, and the reference value of the light output characteristic. In this case, the control unit 15 may store the calculated converted value or the converted value table 200 in the storage unit 13.

[Others]
Since the output instruction signal is corrected so that the light source unit 16 used in the embodiment outputs the light of the reference value, the light source unit 16 may be acceptable if the light source unit 16 can output the reference value or more when the light source unit 16 is manufactured. When the lighting device 10-1 is manufactured, it is determined whether or not the light output characteristic of the light output from the lighting device 10-1 satisfies a predetermined characteristic value according to the output instruction signal for performance evaluation. The When the determination result is a pass determination that satisfies a predetermined characteristic value, the conversion information is stored in the storage unit 13.

  Moreover, since it is not necessary for the illumination device 10-1 to perform color correction while measuring the wavelength, it is not necessary to provide the light device 10-1 with an optical wavelength meter. Moreover, since the illumination apparatus 10-1 does not measure a wavelength after shipment, it is not necessary to consider the measurement accuracy resulting from the measurement position.
