Description

  The present invention relates to a lighting system that regulates the rhythm of the user's breathing by flickering light.

  There are devices and systems for indicating the timing of exhalation and inspiration to the user using voice and video, etc., and guiding the rhythm of breathing so that the user can relax and meditate. For example, in Patent Document 1, a guidance image is displayed on the image presentation device, in which dots are diffused at the time of inhalation and dots diffused at the time of exhalation are collected. Moreover, in addition to the image, the rhythm of breathing is presented by the change of sound.

Patent No. 5081125

Tetsuji Takeuchi, "Perception of Brightness", Journal of the Lighting Society, Vol. 81, No. 6, pages 493-499, 1997 Isamu Motoyoshi, "The signal of change strikes the door of perception-the information selection strategy of the brain revealed by the optical illusion", NTT Technical Journal, September 2010, p. 23-25 Tatsuta, T., "Quantification of flame color of spray flame by correlated color temperature and its application", Proceedings of the Japan Society of Mechanical Engineers, Vol. 72, No. 720, pp. 1875-1879, 2006

  However, in the technique of Patent Document 1, since the video (visual information) and the audio (hearing information) are given to the user, there is a concern that the user receives a large amount of information and thus the degree of relaxation and immersiveness is inferior. . In addition, the device becomes large-scale, and it is difficult to use easily. Furthermore, in the case of using voice, there is a concern that sound leakage to the outside of the space becomes noise.

  On the other hand, a lighting system has been proposed to adjust the rhythm of breathing by blinking of light. In this lighting system, the user does not receive video and audio, so the degree of relaxation and the sense of immersion are considered to increase. In addition, the device configuration is simplified, and the user can easily use it.

  In the case of an illumination system that adjusts the rhythm of breathing by blinking of light, for example, the intensity of output light repeatedly changes as minimum value → increase → maximum value → decrease → minimum value → increase → maximum value → decrease → ... Breathe in a rhythm such as breathing when the light intensity increases and exhaling when the light intensity decreases. In this case, the user can change the timing from the inspiration to the exhalation (in the above example, the timing when the light intensity reaches the maximum value) or the timing from the exhalation to the inspiration (the light intensity becomes the minimum value in the above example) There is a problem that the timing is difficult to understand.

  Therefore, an object of the present invention is to make it easy to understand the timing of switching from inspiration to expiration or expiration to inspiration in an illumination system that adjusts the rhythm of respiration by blinking of light.

  In order to solve the above problems, a lighting system according to an embodiment of the present invention includes a light source unit that emits a first light and a second light having a chromaticity different from that of the first light, the first light and A control unit for temporally changing an output of the second light and giving a change which repeatedly increases and decreases the light intensity to a summed light obtained by adding the first light and the second light; In the process of changing the totalized light from the minimum value to the maximum value, and in the process of changing the maximum value to the next minimum value, when having the first chromaticity and having the maximum value, and the minimum value The output of the first light and the second light is controlled to have a second chromaticity different from the first chromaticity in at least one of the cases of having a value.

  According to the present invention, it is possible to easily understand the timing of switching from inspiration to expiration or expiration to inspiration in an illumination system that adjusts the rhythm of breathing by blinking of light.

  Hereinafter, each embodiment of the present invention will be described in detail based on the drawings. The following description of each embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its application.

  FIG. 1 shows a schematic configuration of a lighting system according to an embodiment. As shown in FIG. 1, in the present embodiment, the illumination system 1 includes a light source unit 10 and a control unit 20 that controls light emitted by the light source unit 10. The light source unit 10 drives a first light source 11 that emits a first light, a second light source 12 that emits a second light having a chromaticity different from that of the first light, and a driving unit that drives the first light source 11 and the second light source 12 And 13. Further, the first light source 10 and the second light source 12 are covered by the same translucent cover 14. The control unit 20 receives an operation signal output by, for example, a user operating a remote control or a switch, and controls the light source unit 10 according to the illumination mode instructed by the operation signal.

-Operation example 1
FIG. 2 shows an operation example of the illumination system 1 according to the present embodiment. FIG. 2A shows an example of the change in the light intensity of the summed light output from the illumination system 1. The summed light is light obtained by summing the first light emitted by the first light source 11 and the second light emitted by the second light source 12. As shown in FIG. 2A, the control unit 20 gives the summed light a change that repeatedly increases and decreases the light intensity. The summed light alternately has a maximum value a1 and a minimum value a2. The user breathes, for example, in a rhythm such that the intensity of the output light inhales as it increases and exhales as it decreases. The combined calculation power of the summed light changes smoothly. Also, the minimum value a2 is larger than zero.

  In this operation example, as shown in FIG. 2B, the summed light has a chromaticity different from that of the other periods in the vicinity of the maximum value a1. That is, the summed light has the first chromaticity and has the maximum value a1 in the process of changing from the minimum value a2 to the maximum value a1 and in the process of changing from the maximum value a1 to the next minimum value a2. When it has a second chromaticity different from the first chromaticity. When it has the local minimum value a2, it remains at the first chromaticity.

  In this operation example, the chromaticity of the summed light changes from the chromaticity in the other period in the vicinity of the maximum value a1. By such an operation, the user can easily recognize the timing at which the light intensity of the summed light reaches the maximum, and can easily grasp, for example, the timing of switching from inspiration to expiration.

  In order to realize the summed light as shown in FIGS. 2A and 2B, the control unit 20 changes the first light and the second light as shown in FIGS. 2C and 2D, for example. . In the examples of FIGS. 2C and 2D, the intensity of the first light and the intensity of the second light change in the same cycle, and have peaks at the same timing. However, the second light has a sharper peak than the first light, and is emitted only in the vicinity where the intensity of the summed light has the maximum value a1. That is, the half width of the intensity of the second light (the time having an output of 50% or more of the maximum output) is smaller than the half width of the intensity of the first light.

  FIG. 3 is a diagram showing one cycle of the operation example of FIG. FIG. 3A shows the change in light intensity of the summed light. As shown in FIG. 3A, the increase / decrease period of the total light includes an increase period in which the light intensity of the total light increases and a decrease period in which the light intensity of the total light after the increase period decreases. Here, the increase period is divided into a first increase period (indicated as increase 1 and shown) and a subsequent second increase period (indicated as increase 2 and shown), and a decrease period is indicated as a first decrease period (indicated as decrease 1). (As shown) and the subsequent second decrease period (as shown as 2).

  Here, the control unit 20 changes the first light as shown in FIG. That is, the light intensity is gradually increased in the first increase period, the light intensity is kept substantially constant in the second increase period and the first decrease period, and the light intensity is gradually reduced in the second decrease period.

  Further, the control unit 20 changes the second light as shown in FIG. That is, while the second light is emitted in the second increase period and the first decrease period, the second light is controlled not to be emitted in the first increase period and the second decrease period. As a result, as shown in FIG. 3D, in the first increase period and the second decrease period in which only the first light is emitted, the summed light has the chromaticity of the first light as the first chromaticity. Have. Then, after the light intensity of the second light becomes sufficiently large in the second increase period, the chromaticity and the first light have the period until the light intensity of the second light becomes sufficiently small in the first decrease period. A chromaticity in which the chromaticity of two lights is mixed is included as a second chromaticity. As a result, the summed light has the second chromaticity when having the maximum value a1.

  In this case, the change from the first chromaticity to the second chromaticity and the change from the second chromaticity to the first chromaticity are smooth according to the change of the light intensity of the second light. become.

  The ratio of the second increase period to the increase period is preferably 50% or less, and the ratio of the first decrease period to the decrease period is preferably 50% or less. As a result, the user can more easily recognize the timing at which the light intensity of the summed light reaches the maximum. Alternatively, the second increase period is preferably 0.5 seconds or more and 1.5 seconds or less, and the first decrease period is preferably 0.5 seconds or more and 1.5 seconds or less. As a result, the user can more easily recognize the timing at which the light intensity of the summed light reaches the maximum.

  The light intensity waveform of the second light is not limited to the sinusoidal waveform as shown in FIG. 2 (d) and FIG. 3 (c). FIG. 4 shows another example of the light intensity waveform of the second light. In FIG. 4A, the light intensity waveform of the second light has a rectangular wave shape. In this case, the change from the first chromaticity to the second chromaticity and the change from the second chromaticity to the first chromaticity in the summed light become discontinuous.

  Further, in the case of FIG. 4A, it is preferable that the pulse width of the second light, that is, the time for outputting the second light be 1.0 second or more. FIG. 5 is a graph which evaluated the time when the pulsed light of various illumination intensity is felt by the brightness equivalent to it (FIG. 7 of nonpatent literature 1). When looking at pulsed light such as flash light, the moment at which it is seen is felt to be very bright, and when the pulse time is prolonged it is felt to have a constant brightness over time. This phenomenon is called the blocker-sulzer effect. Also, for example, when the light source unit 10 is a floor light, when considering the distance from the floor light to the user's face, the illuminance on the user's face is very dark and the second light is pulse light of about 5 lx There is also a possibility. Even in such a case, as shown in FIG. 5, if the pulse width of the second light, that is, the time for outputting the second light is 1.0 seconds or more, no perceptual discomfort occurs in the blink change of the total light Conceivable.

  Further, in FIG. 4B, the light intensity waveform of the second light has a triangular wave shape. In this case, the user can clearly perceive the change in chromaticity by giving about 1 second each to the rise and fall of the light intensity (Non-patent Document 2).

  Further, the light intensity waveform of the first light is not limited to those shown in FIG. 2 (c) and FIG. 3 (b). For example, in FIG. 3, the light intensity of the first light may be further weakened in the second increase period and the first decrease period. Alternatively, the output of the first light may be stopped in the second increase period and the first decrease period. In this case, the chromaticity itself of the second light is the second chromaticity when the summed light has the maximum value a1.

-Difference between the first chromaticity and the second chromaticity The second chromaticity is preferably different from the first chromaticity to such an extent that the user can recognize that the color of light has changed. For example, on the chromaticity diagram of the CIE colorimetric system, the second chromaticity is preferably outside the MacAdam three-step ellipse centered on the first chromaticity. This is because it is said that if the light source is selected with the chromaticity within 3 steps, it is possible to make the colors uniform.

  The second chromaticity preferably has a difference ΔK in color temperature with the first chromaticity of 50 K or more and 400 K or less. The color temperature is a number representing color light as a temperature of a black body (a virtual object that completely absorbs external light), and the unit is K (Kelvin). FIG. 6 shows the color temperature difference ΔK at which the color difference can be perceived and the color temperature K at which the color difference can be perceived at color temperatures of 1000 to 6500K. Further, Mired is a value obtained by multiplying the reverse color temperature (reciprocal of color temperature) by 1,000,000, and the difference in numerical value is approximately proportional to the difference in color difference. In the data of FIG. 6, the color temperature difference ΔK at which the color difference can be perceived is the smallest at 53.8 K when the color temperature 6500 K shown in the rightmost column. From this, it can be said that 50 K is preferable as the lower limit of the difference ΔK in color temperature between the second chromaticity and the first chromaticity.

  On the other hand, if the difference ΔK in color temperature between the second chromaticity and the first chromaticity is too large, the flickering rhythm of the summed light may be unnatural, which may cause a decrease in the user's sense of immersion or the degree of relaxation. Also, the first light, which is the basis of the flickering rhythm, is preferably a low color temperature around 200 K, such as a flame that induces relaxation and calmness.

  FIG. 7 shows the color temperature Tcp of the flame of the spray type oil burner when the various positions L of the flame and the air ratio λ at the time of combustion are changed (FIG. 8 of Non-Patent Document 3). From FIG. 7, the flame color temperature Tcp is in the range of about 1500-2300 K, and the fluctuation range of the color temperature Tcp is about 800 K. If it is 50% (400 K) or less of the fluctuation range of the color temperature Ycp of this flame, it is considered that the change in color temperature with little discomfort. From this finding, it can be said that 400 K is preferable as the upper limit of the difference ΔK in color temperature between the second chromaticity and the first chromaticity.

(Other operation example)
The operation of the illumination system according to the present embodiment is not limited to the above-described operation example 1. Hereinafter, another operation example will be described.

-Operation example 2
FIG. 8 is a diagram showing another operation example of the illumination system 1 according to the present embodiment. FIG. 8A shows an example of the change in light intensity of the summed light output from the illumination system 1. As shown to Fig.8 (a), the control part 20 gives the total light the change which repeats increase / decrease in light intensity. The summed light alternately has a maximum value a1 and a minimum value a2. The change of the light intensity of the summed light is the same as the above-described operation example.

  However, in this operation example, as shown in FIG. 8B, the summed light has a chromaticity different from that in the other periods in the vicinity of the maximum value a1 and in the vicinity of the minimum value a2. That is, the summed light has the first chromaticity and has the maximum value a1 in the process of changing from the minimum value a2 to the maximum value a1 and in the process of changing from the maximum value a1 to the next minimum value a2. When it has a second chromaticity different from the first chromaticity. In addition, when it has the local minimum value a2, it has a third chromaticity different from the first chromaticity.

  In this operation example, the chromaticity of the summed light changes from the chromaticity in the other period in the vicinity of the maximum value a1 and in the vicinity of the minimum value a2. Such an operation makes it easy for the user to recognize the timing at which the light intensity of the summed light becomes maximum and the timing at which the light intensity of the summed light becomes minimum. For example, the timing of switching from inspiration to expiration, and The timing of switching from exhalation to inhalation can be easily grasped.

  In order to realize the summed light as shown in FIGS. 8A and 8B, the control unit 20 changes the first light and the second light as shown in FIGS. 8C and 8D, for example. . In the examples shown in FIGS. 8C and 8D, the second light has a waveform having a peak at the timing when the intensity of the first light becomes maximum, and a waveform having a peak at the timing when the intensity of the first light becomes minimum. And both. As a result, in both of the case where the summed light has the maximum value a1 and the case where the total light has the minimum value a2, it has a chromaticity different from that of the other periods. Further, by changing the ratio of the first light and the second light between when the total light has the maximum value a1 and when the total light has the minimum value a2, the second chromaticity and the third chromaticity are made different. can do. Note that if the ratio of the first light and the second light is made the same between when the summed light has the maximum value a1 and when the total light has the minimum value a2, the second chromaticity and the third chromaticity have the same chromaticity. can do.

-Operation example 3
Further, as in the first operation example, it is also possible to make the light intensity of the total light have a chromaticity different from that of the other period only in the vicinity of the minimum value a2. In this case, for example, the second light may be emitted only at the timing when the intensity of the first light is minimized.

-Operation example 4
FIG. 9 is a view showing another operation example of the illumination system 1 according to the present embodiment. FIG. 9A shows an example of the change in the light intensity of the summed light output from the illumination system 1. As shown in FIG. 9A, the control unit 20 gives the summed light a change that repeatedly increases and decreases the light intensity. The summed light alternately has a maximum value a1 and a minimum value a2.

  However, in this operation example, the increase / decrease period of the total light further includes a sustain period (maximum value a1 is maintained) in which the light intensity is maintained between the increase period and the decrease period. For example, the user breathes in a rhythm such that the intensity of the output light inhales as it increases, holds as it is maintained, and exhales as it decreases.

  Then, as shown in FIG. 9B, the total light has a second chromaticity different from the period other than the start period of the maintenance period and the period near the end period of the maintenance period (pattern A). Alternatively, as shown in FIG. 9C, the total light has the second chromaticity different from the other periods in the entire sustain period (pattern B).

  In order to realize the pattern A shown in FIG. 9B, the control unit 20 changes the second light as shown in FIG. 9D, for example. In the example of FIG. 9D, the second light emits pulse-like output near the start of the sustain period and near the end of the sustain period. That is, after the start of the sustain period, the control unit 20 once extinguishes the second light, and emits the second light again before the end of the sustain period. As a result, the total light has the second chromaticity different from the other periods in the vicinity of the start of the maintenance period and in the vicinity of the end of the maintenance period. Moreover, in order to implement | achieve the pattern B shown in FIG.9 (c), the control part 20 changes 2nd light, as shown, for example in FIG.9 (e). In the example of FIG. 9 (e), the second light emits a pulse-like output from a little before the start of the maintenance period to a little after the end of the maintenance period. That is, the control unit 20 continuously emits the second light during the maintenance period. Thus, the total light has the second chromaticity different from the other periods in the entire sustain period.

  The operation example 4 may be applied in combination with the operation examples 2 and 3 described above. For example, in the operation example 2, a maintenance period for maintaining the maximum value a1 and a maintenance period for maintaining the minimum value a2 may be provided, or a maintenance period is provided for any one of the maximum value a1 and the minimum value a2. May be

-Other Operation Examples In the above-described respective operation examples, although the summed light has been described on the assumption that the maximum value a1 and the minimum value a2 are constant, the present disclosure is not limited to this.

  FIG. 10A shows an example of the change in the light intensity of the summed light output from the illumination system 1. In this example, the maximum value of the summed light gradually decreases as a11 → a12 → a13 → a14. Even in such a summed light, as shown in FIG. 10 (b), in the vicinity of the local maximum values a11, a12, a13 and a14, a color different from that in the other periods, as in the above-described operation example. It can be made to have a degree.

  Also, other changes may be given to the maximum value and the minimum value of the summed light. For example, the minimum value may be gradually increased, or the maximum value and the minimum value may change periodically.

  Moreover, although the length of one period of the increase / decrease period of the total light is described as being constant in each operation example described above, the length of one period may be changed. Examples of changes include gradually lengthening, gradually shortening, random length, and fluctuation in length change.

  As described above, in the illumination system according to the present embodiment, the light source unit 10 that emits the first light and the second light having a chromaticity different from that of the first light, the output of the first light and the second light And a control unit 20 for changing the light intensity repeatedly to increase and decrease the sum light obtained by adding the first light and the second light. Then, the control unit 20 has the first chromaticity and has the maximum value in the process in which the summed light changes from the minimum value to the maximum value and in the process in which the maximum value changes to the next minimum value. The output of the first light and the second light is controlled to have a second chromaticity different from the first chromaticity at least one of the time and the local minimum value.

  Thereby, the summed light output from the light source unit 10 repeats the increase and decrease of the light intensity and is different from the other period in at least one of the time when it has the maximum value and the time when it has the minimum value. It has a chromaticity. Therefore, for example, when the user breathes with a rhythm such as inhaling when the light intensity increases and exhaling when the light intensity decreases, the timing of switching from inspiration to expiration or the timing of switching from expiration to inspiration Is easier to grasp. Therefore, the user can easily take a deep breath and relax using the lighting system according to the present embodiment.

  In addition, an increase period is a first increase period and a first increase period in an increase / decrease period including an increase period in which the light intensity of the combined light increases and a decrease period after the increase period in which the light intensity of the combined light decreases. When the control unit 20 divides the decrease period into the first decrease period and the second decrease period after the first decrease period, the control unit 20 divides the first light into at least the first increase period after the period. The first light is emitted in the first increase period and the second decrease period, and the second light is emitted in the second increase period and the first decrease period, but not in the first increase period and the second decrease period. When having a maximum value, it may be assumed to have a second chromaticity. Thus, when the summed light output from the light source unit 10 has a maximum value, it has a second chromaticity different from that of the other periods. For this reason, for example, when the user breathes with a rhythm such as inhaling when the light intensity increases and exhaling when the light intensity decreases, it becomes easy to grasp the timing of switching from inspiration to expiration. In addition, the change of the chromaticity at the maximum value of the summed light can be realized by simple control.

  Furthermore, the intensity of the first light and the intensity of the second light change in the same cycle and have peaks at the same timing, and the half width of the second light intensity is greater than the half width of the first light intensity It may be small. Thereby, the change of the chromaticity at the maximum value of the total light can be easily realized by the simple control.

  Also, the increase / decrease period may further include a maintenance period in which the light intensity of the added light is maintained between the increase period and the decrease period. This allows the user to breathe in a rhythm such as breathing when the light intensity increases, holding the breath when maintained, and exhaling when the light intensity decreases.

  Furthermore, the control unit 20 may continuously emit the second light during the maintenance period. As a result, during the sustain period, the chromaticity of the summed light can be made different from that of the other periods.

  In addition, the control unit 20 may temporarily turn off the second light after the start of the maintenance period and emit the second light again before the end of the maintenance period. As a result, the chromaticity of the summed light can be made different from that in the other periods in the vicinity of the beginning and the end of the sustain period.

  The ratio of the second increase period to the increase period may be 50% or less, and the ratio of the first decrease period to the decrease period may be 50% or less. As a result, the user can more easily recognize the timing at which the light intensity of the summed light reaches the maximum.

  The second increase period may be 0.5 seconds or more and 1.5 seconds or less, and the first decrease period may be 0.5 seconds or more and 1.5 seconds or less. As a result, the user can more easily recognize the timing at which the light intensity of the summed light reaches the maximum.

  In addition, the second chromaticity may be outside the MacAdam three-step ellipse centered on the first chromaticity on the chromaticity coordinates. Thereby, the user can recognize the change of the chromaticity of the summed light.

  The color temperature difference between the first chromaticity and the second chromaticity may be 50 K or more and 400 K or less. Thus, the user can recognize the change in the chromaticity of the summed light and does not have a sense of incongruity.

  Further, the combined calculation force of the summed light may be changed smoothly.

  Also, the minimum value may be larger than zero.

  In addition, the light source unit 10 includes a first light source 11 that emits a first light and a second light source 12 that emits a second light. The first light source 11 and the second light source 12 are formed by the same translucent cover 14 It may be covered.

Moreover, it is also possible to combine each component demonstrated by the said embodiment, and to set it as a new embodiment.

  The above-described embodiment may be configured as follows. For example, the first light source 11 that emits the first light and the second light source 12 that emits the second light may be included in separate units. For example, the first light source 11 may be a floor light, and the second light source 12 may be a downlight. Moreover, the 1st light source 11 which emits 1st light may be one light source, and may consist of several light sources. Similarly, the second light source 12 emitting the second light may be a single light source or may be composed of a plurality of light sources.

  Further, in the above embodiment, the minimum value a2 of the intensity of the summed light is larger than zero, but the minimum value may be zero. This makes it easier to understand, for example, the timing of switching from exhalation to inhalation.

  The illumination system according to the present disclosure may be configured in combination with a system that outputs video and audio.

  Further, the control unit 20 may be included in a control device configured separately from the light source unit 10. The control device controls the light source unit 10 to perform the above-described operation in response to a user operation. Furthermore, it is also possible to use a portable device such as a smartphone as this control device. In this case, an embodiment is also possible in which a program for executing a control method for controlling the light source unit 10 to perform the above-described operation is downloaded to the portable device, and this program is executed.

  That is, the present disclosure is a control device, and includes a control unit 20 that controls the light source unit 10 that emits the first light and the second light having a chromaticity different from the first light, and the control unit 20 The output of the first light and the second light is temporally changed, and a change which repeatedly increases and decreases the light intensity is added to the combined light obtained by adding the first light and the second light, and the control unit 20 In the process of changing from a value to the maximum value, and in the process of changing from the maximum value to the next minimum value, at least one of the first chromaticity and the maximum value and the minimum value In any one of the above, one that controls the outputs of the first light and the second light so as to have a second chromaticity different from the first chromaticity is included.

  Further, the present disclosure is a control method for controlling the light source unit 10 that emits the first light and the second light having a chromaticity different from the first light, and temporally outputs the first light and the second light.
