Description

  TECHNICAL FIELD The present invention relates to a bathroom lighting device that enables lighting so that a user can relax and take a bath.

  Conventionally, a bathtub illuminator that floats on the water surface in a bathtub is known from Patent Document 1. This bathtub illuminator is suspended on the water surface in the bathtub to illuminate a space above the water surface. In this way, when illuminating the space above the water surface, red, orange, yellow, green, light blue, blue, and purple light colors are combined by combining the red light emitting diode, blue light emitting diode, and green light emitting diode. In order to illuminate the space above the surface of the water with a light color change pattern that changes the light color by circulating in order, so that the space above the surface of the bathtub is illuminated with colorful light using the three primary colors of light It has become.

  In the conventional example shown in Patent Document 1 above, the space above the water surface of the bathtub is illuminated with a light color change pattern in which the light color changes colorfully. It's hard to expect.

  In other words, since the space above the water surface of the bathtub is illuminated with a light color change pattern in which the light color changes colorfully, direct illumination with a light color change pattern in which the space above the water surface, that is, the space in the bathroom changes colorfully Moreover, since the bathtub luminaire floats, the illumination light moves irregularly in the bathroom space. In this way, light with colorfully changing light colors irregularly moves in the bathroom space and directly illuminates the bathroom space. Therefore, a pleasant atmosphere is produced by light stimulation with direct light that changes the light color. For those who want to take a relaxing bath while enjoying light stimulation with direct light that changes light color, and for those who want to take a relaxing bath, the light color in the above conventional example changes with direct light. Light stimulation is too intense and interferes with relaxing bathing.

  In addition, the conventional lighting that uses the three primary colors of light to change in a colorful manner is to enjoy the light color by changing the light color of red, orange, yellow, green, light blue, blue and purple in order. Bathing is a bath, and the red color, which is an exciting color, is also necessary in the sense that it provides a pleasant atmosphere with light stimulation by the bather. However, for those who are going to relax by taking a bath, among the three primary colors of light, the red light color is too irritating for the bather and hinders relaxation, and in this respect as well, relaxing bathing cannot be expected in the conventional example. . In particular, in the above-described conventional example, the red light color such as red and orange changes to a yellow light color, so that the illumination with the red light color continues, and the afterimage of the red light color remains yellow. Therefore, the yellow light color is recognized as being continuous with the red light color, and is much more irritating for bathers.

Therefore, it is conceivable to illuminate blue and green light colors in order without using red light, but this makes the light color colorful and lacks colorful circulation illumination. .
JP 2004-281186 A

  The present invention has been invented in view of the above-mentioned conventional problems, and can provide fantastic colorful underwater lighting that does not cause strong irritation to bathers, resulting in a feeling of relaxation that cannot be obtained by conventional bathing. It is an object to provide a bathroom lighting device.

  In order to solve the above problems, the bathroom lighting device according to the present invention includes an underwater lighting fixture 3a that illuminates the underwater of the bathtub 2, and the underwater lighting fixture 3a includes a green light emitter, a blue light emitter, and a red light emitter. By providing a light source unit 4 and performing color matching by combining each light emission of the above three types of light emitters in the light source unit 4, a green light color, a green and blue intermediate color light color, a blue light color, A control unit 5 is provided for controlling to illuminate in a colorful circulation light emission mode in which light colors of blue and red intermediate colors, red light colors, and green and red intermediate colors are sequentially circulated to emit light, In the above-mentioned colorful circulation light emission mode, when changing from a light color of blue and red to a light color of green and red through a light of red light, the light of the intermediate color of blue and red is changed to red. As a light system, it changes to a pink light color. It is characterized in be controlled to change to green and red neutral system light color through the white light from the color.

  By having such a configuration, the bath water itself in the bathtub 2 is illuminated by the underwater lighting fixture 3a, and the body is immersed in the bath water in a fantastic atmosphere in which the bath water itself in the bathtub 2 emits color light. It is possible to relax and take a bath, and since the part exposed from the surface of the body is not directly color illuminated like the conventional one that directly illuminates the space above the surface of the water, The arm, chest, head, face, etc. coming out from the top are directly illuminated by light such as red, green, blue, or purple and do not stain red, green, blue, or purple. You can soak in a relaxing bathing bath. Also, green light colors, green and blue light colors, blue light colors, blue and red light colors, red light colors, and green and red light colors. Since the light is circulated in order, the light colors of the three primary colors and the light colors of each intermediate color can be circulated in order to produce colorful underwater illumination, and to make the bath water itself more fantastically illuminate. Can do.

  Moreover, when changing from a light color of an intermediate color system of blue and red to a light color of an intermediate color system of green and red through a light color of a red light system, the light color of the intermediate color system of blue and red is changed to pink as a red light system. It is controlled so that it changes from a light color of pink to a light color of intermediate color between green and red through white light, so the red light color is not used as a primary light color. Only the pink color with relatively little irritation to the person is used, and the irritation given to the bather by the red primary color can be eliminated. Also, immediately after the pink light emission used as the red light color, if it changes to the light color of the green and red intermediate color system, for the bather to emit light by the light color of the green and red intermediate color system, Since the afterimage of pink, which is a red color, remains, the light color of green and red is felt as a continuation of the red color, which hinders relaxing bathing, but the pink light Since the color changes from white light to green and red intermediate color, the change to white light erases the pink afterimage, which is a red color, and changes to green and red intermediate color. When changed, it is possible to prevent the red light color from being continuously felt, and the irritation to the bather due to the continuous red light color can be minimized.

  Thereby, while the bath water itself in the bathtub 2 can be light-emitted fantastically by the illumination whose light color changes colorfully, relaxing bathing is possible with as little stimulus to the bather as possible.

  In the present invention, fantastic colorful lighting that does not cause strong stimulation to the bather in the bath water in the bath can be achieved, and a relaxed feeling that cannot be obtained by conventional bathing is obtained.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  1 to 8 show an embodiment of the present invention. A main lighting fixture 8 for directly illuminating the interior space of the bathroom 1 is provided on the upper part or the ceiling portion 7 of the wall 6 of the bathroom 1. In the present invention, the main illumination fixture 8 for directly illuminating the interior space of the bathroom 1. In addition, the bathtub 2 provided in the bathroom 1 is provided with an underwater lighting device 3a for illuminating the bath water in the bathtub 2, and a substantially intermediate position in the vertical direction of the wall 6 of the bathroom 1 (the bathtub A wall surface indirect lighting device 3b for indirectly illuminating the vicinity of the wall surface is provided at a position slightly above the upper end of 2.

  FIG. 1 shows a block configuration diagram of the above embodiment. By operating each operation button provided on the operation device 9 installed in the bathroom 1, the controller 5 controls the underwater lighting device 3a and the wall surface indirect lighting device 3b. The main lighting fixture 8 is controlled. In the figure, 20 is a main switch, which is provided outside the bathroom 1 (dressing room).

  An incandescent lamp or a fluorescent lamp is used as the main lighting fixture 8, but in the case of an incandescent lamp, the brightness of the space in the bathroom 1 can be freely changed by making the light control possible. 1 and 2 show an example of the main lighting device 8 capable of dimming.

  The underwater lighting fixture 3a is provided on the bathtub wall 2a along the longitudinal direction of the bathtub 2 having a substantially rectangular shape in plan view, and is provided from the underwater lighting fixture 3a provided on the one bathtub wall 2a side along the longitudinal direction. The emitted light can be illuminated underwater toward the other bathtub wall 2a along the longitudinal direction without being blocked by a person bathed in the bathtub 2. That is, as shown in FIG. 3, in the case where the bather bathes in the bathtub 2 with his knees bent into a substantially square shape, or in the case of bathing with his legs extended, the water provided on the one side of the bathtub wall 2 a is used. The light emitted from the luminaire 3a can be illuminated underwater toward the other bathtub wall 2a without being blocked by a person bathed in the bathtub 2. The knee position bent in a substantially square shape in the bathtub 2a is substantially the middle in the longitudinal direction of the bathtub wall 2a in the longitudinal direction, and the height position is below the knee bent in a substantially square shape in the bathtub 2. The height is set such that the illumination light passes over the knee at a position where the illumination light passes and when the legs are extended along the bottom of the bathtub 2. In FIG. 3, reference numeral 25 denotes a bather, and 26 denotes a knee of the bather 25.

  The underwater lighting fixture 3a includes a light source unit 4 including a red light emitter made of a red light emitting diode, a green light emitter made of a green light emitting diode, and a blue light emitter made of a blue light emitting diode. By adjusting the light amounts of the three primary colors of red (R), green (G), and blue (B) emitted from each of the light emitters, it is possible to emit various colors. Here, in the present invention, the light emission of the three types of light emitters in the light source unit 4 is combined and toned, so that a green light color, an intermediate color light color between green and blue, and a blue light. It has a colorful circulation light emission mode in which light is emitted by sequentially circulating colors, blue and red light colors, red light colors, and green and red light colors. In addition, it has a cold color circulation light emission mode in which a plurality of light colors of blue color are circulated in order to emit light, and further emits light in a fixed color selected from the plurality of light colors and brightness of the fixed color. It has a fixed color brightness fluctuation mode that automatically changes the brightness.

  As described above, the colorful circulation emission mode is a green light color, a light color of green and blue, a light color of blue, a light color of blue and red, a light color of red, and green. This is a mode in which light colors of red intermediate color system are circulated in order and emitted light.In the present invention, light colors of blue and red intermediate color systems are passed through red light system light colors of green and red intermediate color systems. When changing to light color, the light color of blue and red is changed from pink to red as red light, and the light from pink to white is changed to light between green and red. It controls to change.

  As described above, this colorful circulation light-emitting mode circulates all colors, that is, three primary colors, intermediate colors, and a total of seven light colors in order. For example, green (green) System) → light blue (green and blue intermediate color system) → blue (blue system) → purple (blue and red intermediate color system) → pink (red system) → white → yellow (intermediate color system between green and red) …… The light color changes in this order. FIG. 4 shows the light colors circulated and emitted in the colorful circulation light emission mode based on the chromaticity diagram of the CIE color display system.

  As apparent from FIG. 4, in the colorful circulation light emission mode of the present invention, green light color, green and blue intermediate color, blue light color, and blue and red intermediate color. , Red light color, green and red light colors are circulated in order, and light is emitted, so the light colors of the three primary colors and light colors of each intermediate color are circulated in order to create colorful underwater Illumination is possible, and bath water itself can be fantastically colored. However, in the underwater lighting in the bathtub 2 for relaxing both mentally and physically by bathing, the red color is an exciting color, so it is better to avoid it as much as possible from the viewpoint of relaxing.

  For this reason, the present invention eliminates the stimulus given to the bather by using only the pink light that does not use the primary color of red as the red light color, and uses only the pink color that has relatively little stimulus to the bather. In addition, after the pink light emission used as the red light color, immediately after changing to the light color of the green and red intermediate color system, when the light is emitted by the light color of the green and red intermediate color system, the bather For this, a pink afterimage, which is a reddish color, remains, and the light color of the green and red colors is felt as a series of reddish colors, which hinders relaxing bathing, but pink Because it is controlled so that the light color changes from white light through white light to a light color of green and red, the pink afterimage, which is a red color, is erased by the change to white light. When changing to a neutral color, the red color It is designed not to feel the afterimage of the red color to continue, so that even if it uses a red light color and colorful circulation light emission, the stimulation to the bather due to red is minimized, The bath is relaxed by soaking in an unprecedented and fantastic bathing water that circulates in a colorful manner.

  In the cold-color circulation light emission mode,... Blue → green blue → light blue → blue green → blue → .... FIG. 5 shows the light color that circulates and emits light in the cold color circulation emission mode based on the chromaticity diagram of the CIE color display system.

  In this way, underwater illumination in the bathtub 2 is performed by sequentially circulating a plurality of light colors of cold colors, soaking in the fantastic bath water that is shining while the subtle blue color changes slightly. You can take a bath more relaxedly.

  In any of the colorful circulation light emission mode and the cold color circulation light emission mode, the light color is controlled to automatically change with the preset light color change pattern as described above. The light color that automatically changes in each cyclic light emission mode may be controlled so as to automatically change in a preset brightness change pattern.

  The fixed color brightness fluctuation mode is created by adjusting the light quantity of each of the three primary colors red (R), green (G), and blue (B) emitted from three types of light emitters and changing the mixing ratio. The controller 5 controls the control unit 5 to emit light as a fixed color and to automatically change the brightness of the selected fixed color based on a preset brightness change pattern. Is done.

  An example of selecting a fixed color is to select a fixed color from 10 colors of yellow, yellow green, green, blue green, light blue, green blue, blue, purple, pink and white. By pressing the color selection operation buttons 12 (described later) provided on the operation unit 9 in order, the single color selected in order from the ten colors can be set as a fixed color. The color selected as such a fixed color and the order of selection are shown in FIG. 7 based on the chromaticity diagram of the CIE color display system.

  When the brightness of the selected fixed color is automatically changed, the brightness change pattern automatically changes in accordance with a preset change pattern. FIG. It is a graph which shows an example of the changed change pattern of the brightness. In FIG. 6, time A is the time of the set maximum brightness, B is the time from the maximum brightness until the brightness gradually decreases to the minimum brightness, and C is the minimum brightness. D represents the time from the minimum brightness to the maximum brightness, and the times A, B, C, and D are obtained as follows. That is, the experimenter actually bathed in the hot water of the bathtub 2, illuminated the hot water in the bathtub 2 with the selected fixed color, and changed the brightness to evaluate the psychological state of the bather. Based on the psychological evaluation of the bather in such an experiment, the change pattern of the brightness that the bather is most relaxed is obtained, and based on the change pattern of the brightness thus obtained, the above A, B, C, The time for D was determined. By the way, according to experiments, A and C are preferably about 3 seconds, and B and D are preferably about 10 seconds.

  The wall surface indirect lighting device 3b is installed at a substantially intermediate position in the vertical direction of the wall 6 of the bathroom 1 (a position slightly above the upper end of the bathtub 2), and is composed of an LED at the rear of the box 13 as shown in FIG. A light emitter 14 is provided. The box 13 is made of a synthetic resin such as ABS having a light-shielding property and chemical resistance at the front wall portion 13a and both side wall portions, and the top wall portion 13c and the bottom wall portion 13d are light-transmissive and resistant. It consists of synthetic resin such as PP having chemical properties. The light emitter 14 emits light toward the front wall portion 13a of the box 13, and this light hits the front wall portion 13a and the side wall portion and is reflected to pass through the top wall portion 13c and the bottom wall portion 13d. Indirect illumination is realized by light leaking upward and downward. The wall surface indirect lighting fixture 3b composed of such indirect lighting illuminates lightly with soft indirect lighting near the wall surface corresponding to the eye level of the person bathing in the hot water in the bathtub 2. The light of the wall indirect lighting device 3b does not enter directly into the bather's eyes, and a relaxing effect can be given to the bather who is immersed in the hot water in the bathtub 2 by the soft indirect light. Yes.

  Next, operation of the underwater lighting fixture 3a, the wall surface indirect lighting fixture 3b, and the main lighting fixture 8 will be described based on the control unit lock diagram of FIG. 1 and the operation explanatory diagram of FIG.

  When entering the bathroom 1, the bather enters the bathroom 1 by turning on the main switch 20 provided outside the bathroom 1. When the main switch 20 is turned on, the main lighting device 8 is turned on by the control unit 5. Here, the embodiment shown in FIGS. 1 and 2 is an example in the case where the main lighting fixture 8 is dimmable. In this case, when the main switch 20 is turned on, the main lighting fixture 8 is turned on. (100% lighting) state. This state is the initial state in FIG.

  In the full lighting state of the main lighting fixture 8, the lighting in the bathroom 1 similar to general bathroom lighting can be realized.

  In the full lighting state of the main lighting fixture 8, the controller 5 turns on the underwater lighting fixture 3a by pressing the underwater lighting operation button 10 provided on the operating device 9 so that it is illuminated in the colorful circulation light emission mode. To be controlled. At the same time, the brightness of the main lighting fixture 8 is automatically lowered (for example, lowered to 20% of the brightness of the full lighting state) and the space in the bathroom 1 is controlled to be dim.

  When the circulation switching operation button 11 provided on the operation unit 9 is further pressed during illumination in the colorful circulation light emission mode, the underwater lighting device 3a is switched from the colorful circulation light emission mode to the underwater illumination in the cold color circulation light emission mode. Furthermore, when the circulation switching operation button 11 is pressed, the underwater illumination in the colorful circulation light emission mode is switched again. Thus, every time the circulation switching operation button 11 is pressed, the colorful circulation light emission mode and the cold color circulation light emission mode can be switched alternately.

  In addition, when the color selection operation button 12 is pressed during underwater illumination in the colorful circulation light emission mode or the cold color circulation emission mode, the underwater illumination in the colorful circulation emission mode or the cold color circulation emission mode is switched to the fixed color brightness fluctuation mode. It is done. Here, by pressing the color selection operation button 12 once, twice,..., A plurality of preset fixed colors (10 colors in the embodiment) are selected in order. In this fixed color brightness fluctuation mode, when the bath water is emitted with a fixed light color, the brightness automatically changes based on a preset brightness change pattern, so the light color is fixed. When bathing in bathing water, bath water illumination can be performed with the most appropriate brightness change that can be most relaxed based on the psychological evaluation of the bather, without being affected by the undulation of the water surface as in the past.

  In addition, in FIG. 2, the case where bath water illumination is performed with the underwater lighting fixture 3a turned on is illustrated by painting the bath water in the bathtub 2 in black, and the bath water in the bathtub 2 is white. The case where the underwater lighting fixture 3a is off is shown.

  When underwater illumination is performed as described above, the bath water itself in the bathtub 2 is directly illuminated by the underwater lighting fixture 3a, and the bath water itself emits color light. In this case, since the brightness of the main lighting fixture 8 is automatically reduced at the same time as the underwater lighting fixture 3a is turned on and the interior of the bathroom 1 becomes dim, the bath water in the bathtub 2 is fantastic in the dimly lit bathroom 1. An unprecedented fantastic atmosphere of color emission can be revealed, and relaxing bathing becomes possible by soaking in bath water that emits a fantastic color in such an atmosphere. In this case, since the bath water is irritated by a single color emission of the bath water, in the present invention, as described above, the circulation emission mode such as the colorful circulation emission mode and the cold circulation emission mode, and the fixed color brightness. Select the fluctuation mode, select a suitable underwater lighting mode from multiple underwater lighting modes according to the bather's preference, physical condition and psychological state at that time, and create a fantastic light emission state suitable for the bather By bathing in the bathing water that appears, you can relax and take a bath.

  When the underwater lighting fixture 3a is turned on and underwater lighting is performed in one of a plurality of light emission modes, the brightness of the main lighting fixture 8 can be varied by operating the dimming operation button 15 provided on the operation unit 9. In accordance with the preference of the bather of the user and the physical condition and psychological state at that time, the brightness of the interior space of the bathroom 1 is set to the most suitable brightness so that a more relaxing atmosphere appears. Of course, all the lights can be turned off by operating the light control button 15 for light control.

  In order to turn off the underwater lighting fixture 3a, the underwater lighting fixture 3a can be turned off by pressing the underwater lighting operation button 10 provided on the operating device 9 again. When the underwater lighting fixture 3a is turned off, the main lighting fixture 8 is controlled by the control unit 5 so as to be automatically turned on.

  When the indirect lighting operation button 16 provided on the operation unit 9 is pressed, the wall surface indirect lighting device 3b is turned on, the wall surface indirect lighting device 3b is turned on, and the vicinity of the wall surface is indirectly illuminated. It is controlled by the control unit 5 so that it is turned off and turned off. Thus, when the wall surface indirect lighting device 3b is pushed and turned on, when the underwater lighting device 3a is turned on, the underwater lighting continues the current mode, and when the underwater lighting device 3a is turned off. Control is performed so that the off state is maintained.

  In this way, the main lighting fixture 8 is automatically turned off during indirect lighting by the wall surface indirect lighting fixture 3b, so that there is no light stimulation by direct lighting and bathing can be performed in a soft indirect lighting atmosphere, and relaxing. You can take a bath. Further, in this state, the main lighting fixture 8 can be dimmed by operating the dimming operation button 15.

  Further, when both the underwater lighting fixture 3a and the wall surface indirect lighting fixture 3b are turned on and the main lighting fixture 8 is turned off and turned off, either the underwater lighting fixture 3a or the wall surface indirect lighting fixture 3b is turned off. The main lighting fixture 8 remains off and is extinguished. However, when both the underwater lighting fixture 3a and the wall surface indirect lighting fixture 3b are turned off, the main lighting fixture 8 is automatically turned on and controlled to be all lights.

  Therefore, when the main switch 20 is turned on, any one or more of the main lighting fixture 8, the underwater lighting fixture 3a, and the wall surface indirect lighting fixture 3b are turned on and turned on so that the interior of the bathroom 1 is not dark. It is designed to avoid the danger of darkness.

  In the above embodiment, the example in which the main lighting fixture 8 is dimmable has been described. However, the main lighting fixture 8 may not be dimmable. Hereinafter, operations of the underwater lighting fixture 3a, the wall surface indirect lighting fixture 3b, and the main lighting fixture 8 will be described based on the block configuration diagram of the present embodiment shown in FIG. 9 and the operation explanatory diagram shown in FIG.
