Description

  TECHNICAL FIELD The present invention relates to a bathroom lighting device that can be lit so that it can be immersed in hot water in a bathtub and relaxed.

  Conventionally, a bathtub illuminator that floats on the water surface in a bathtub is known from Patent Document 1. This bathtub lighting fixture is designed to illuminate the space above the water surface by floating on the water surface in the bathtub, and a light color changing pattern that changes the light color and a light color fixing pattern that fixes the light color As the water surface undulates and the bathtub luminaire vibrates, the light intensity is changed. In other words, when the water surface is greatly swollen and the bathtub luminaire vibrates greatly, it outputs light with high light intensity, and when the vibration is small, it outputs light with low light intensity so that the space above the water surface of the bathtub is intended. Illuminated with abundant light, you can take a bath while enjoying the interior of the bathroom with various colors.

  In the conventional example shown in Patent Document 1, the space above the water surface of the bathtub is illuminated with a light color change pattern in which the light color changes, or illuminated with a light color fixed pattern that fixes the light color. It is not only for lighting to switch bathing and enjoying bathing, but it is relaxing by bathing in an unprecedented fantastic bathing water by directly illuminating the water in the bathtub (bath water) It does not relate to underwater lighting that allows bathing. That is, in the conventional example, the bath water itself in the bathtub does not shine while changing the light color, or the light color is not fixed and does not shine.

  In this way, the bath water itself in the bathtub is not underwater illumination that is directly illuminated, so the conventional example does not leave the area of direct illumination of the space in the bathroom, so bathe in the bathtub. The area above the surface of the person's body will be directly illuminated with various and fixed colors, for example, the arms, chest, head, face, etc. When illuminated with light such as red, green, blue, or purple, it is dyed red, green, blue, or purple. In this way, the arm, chest, head, face, etc. that are above the surface of the water are directly illuminated by light such as red, green, blue, or purple, and dyed red, green, blue, or purple. Is very uncomfortable for those who are immersed in the bathtub, and for those who are immersed in the bathtub to relax, the feeling of relaxation is greatly reduced, and it is sufficient as bathroom lighting for relaxing bathing I can't say there is.

  Moreover, in the conventional example shown in Patent Document 1, since the brightness changes depending on the level of the water surface in the bathtub, the water surface greatly waves at the beginning when the bather enters the water in the bathtub. Therefore, the brightness of each light color that changes is maximized, it becomes darker when the wave becomes smaller, it becomes darker when the bather moves in the bathtub and the wave becomes larger, and the water surface is greatly waved and bright when leaving the bathtub. In this way, it is possible to illuminate with light that is rich in taste by lighting up and down the space above the water surface of the bathtub according to the state of waves, but in this way Since the brightness changes irregularly, for example, suddenly switching from light to dark and from dark to light disturbs bathing by stimulating the bather. In particular, it moves brightly every time the surface of the water moves while it is immersed in the water in the bathtub, so the relaxation is impaired due to sudden light stimulation regardless of the light and dark rhythm based on the psychological evaluation of the bather Also, when you get out of the bathtub, the water surface is the most rippled and brightest, so you relaxed when you finally got out of the bathtub. There is a problem that it will be.

Furthermore, in the said prior art example, since a bathtub lighting fixture floats on the water surface, there exists a problem of interfering with bathing.

  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 luminaire 8 for directly illuminating the space in the bathroom 1 is provided on the top or ceiling 7 of the wall 6 of the bathroom 1. 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 (from the upper end of the bathtub 2). In the slightly upper position), a wall surface indirect lighting device 3b for indirectly illuminating the vicinity of the wall surface is provided.

  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, by combining the light emission of the three types of light emitters in the light source unit 4 and adjusting the color, light colors of various hues can be emitted. In the present invention, the underwater illumination by the underwater lighting fixture 3a includes a light color change mode in which the light color automatically changes in a preset light color change pattern, a light color fixed to a single color, and brightness. A fixed color brightness fluctuation mode that automatically changes according to a preset brightness change pattern.

  The light color change mode is green light color, green and blue intermediate light color, blue light color, blue and red intermediate light color, red light color, green and red intermediate color system There are two modes: a colorful circulation light emission mode in which light colors are circulated in order, and a cold color circulation light emission mode in which a plurality of blue light colors are circulated in order to emit light.

  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 emits the selected single color as a fixed color, and the selected fixed color automatically changes the brightness of the fixed color based on a preset brightness change pattern. Be controlled.

  An example of selecting a fixed color is to select one color (single color) from 10 colors of yellow, yellow-green, green, blue-green, light blue, green-blue, blue, purple, pink, and white and set it as a fixed color. By pressing the color selection operation buttons 12 (described later) provided on the operation unit 9 in order, the ten colors can be selected in order and set as fixed colors. 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.

  During the illumination in the colorful circulation light emission mode, when the operation button for circulation switching 11 provided on the operation unit 9 is further pressed, the underwater lighting fixture 3a is switched from the colorful circulation light emission mode to the underwater illumination in the cold color circulation light emission mode. 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.

  In the embodiment described above, the operation device 9 is provided with the light adjustment operation button 15 for adjusting the main lighting fixture 8. However, in this embodiment, the operation button 9 is replaced with the light adjustment operation button 15 as shown in FIG. A main illumination on / off operation button 18 is provided.

  Also in this embodiment, when the main switch 20 is operated and turned on, the main lighting fixture 8 is turned on. In this state, even if the underwater illumination operation button 10 is pressed to turn on the underwater illumination fixture 3a to perform underwater illumination, the main illumination fixture 8 is in a lighting state, and then the main illumination on / off operation button during underwater illumination. The main lighting fixture 8 can be turned off by operating 18.

  On the other hand, when the operation button 10 for underwater illumination is pressed again to turn it off, the main lighting fixture 8 is automatically turned on.

  The operations of the circulation switching operation button 11 and the color selection operation button 12 are the same as those in the above-described embodiment, and thus description thereof is omitted.

  When the indirect lighting operation button 16 is operated to turn on the wall surface indirect lighting device 3b, the main lighting device 8 is automatically turned off automatically. In this indirect lighting state, the main lighting fixture 8 can be turned on by operating the main lighting on / off operation button 18.

  In the indirect lighting state by the wall surface indirect lighting device 3b, when the main lighting device 8 is off, the main lighting device 8 is automatically turned on by operating the indirect lighting operation button 16 to turn off the wall surface indirect lighting device 3b.

  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 on and turned off, the indirect lighting operation button 16 is operated to turn off the wall indirect lighting fixture 3b. However, when the underwater lighting fixture 3a is on, the main lighting fixture 8 remains off. In this case, by operating the underwater lighting operation button 10 to turn off the underwater lighting fixture 3a, the main lighting fixture 8 is turned off. Lights up automatically. 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 on and turned off, the underwater lighting operation button 10 is operated to turn off the underwater lighting fixture 3a. However, when the wall surface indirect lighting fixture 3b is on, the main lighting fixture 8 remains off.

  11 and 12, the fixed color brightness constant operation button 24 during underwater illumination in the light color change mode (colorful circulation light emission mode, cold color circulation light emission mode) or the fixed color brightness fluctuation mode. When is pressed, switching from underwater illumination in the light color change mode (colorful circulation light emission mode or cold color circulation light emission mode) or underwater illumination in the fixed color brightness fluctuation mode to the fixed color brightness constant light emission mode. Here, by pressing the fixed color brightness constant operation button 24 once, twice,..., A plurality of preset fixed colors (in the embodiment, the same 10 colors as the fixed color brightness fluctuation mode) are obtained. Selected in order. In this fixed color brightness constant light emission mode, when the bath water emits light with a fixed light color fixed to the selected single color, the light is emitted at a predetermined constant brightness, and the light color is selected. When bathing in bathing water that is fixed in a single color, bathing lighting is at the optimum brightness that is most relaxing based on the psychological evaluation of the bather, without being affected by the undulation of the water surface as in the past. it can.

  In the present invention, a fine bubble generator (not shown) is attached to the bathtub 2 and the fine bubbles generated by the fine bubble generator are discharged into the bathtub 2 from the discharge port of the fine bubble generator. You may make it mix in hot water. As the fine bubbles, those having an average bubble diameter of about 10 μm to 20 μm are preferable. The fine bubbles having an average bubble diameter of about 10 μm to 20 μm have a long residence time in the hot water and are evenly dispersed in the hot water in the bathtub 4. The entire hot water is made opaque muddy water, and light is irradiated from the light irradiation unit 6 in the same direction as the discharge direction of fine bubbles having an average bubble diameter of about 10 μm to 20 μm. Illuminates and reflects the fine bubbles of about 10 μm to 20 μm, and repeats this, while the muddy water in which the entire hot water in the bathtub 4 emits light with a light color of an arbitrary hue as the fine bubbles are dispersed throughout the region. Can appear.

  In the colorful circulation light emission mode, as described above, the light color is circulated while changing in order, so that the colorful muddy water can be displayed in order, with the light color changing one after another. In the cold-color circulation mode, the cold light color changes one after the other so that multiple colors of cold-colored muddy hot water that appear to emit light can be displayed in sequence, and the fixed color brightness fluctuations In the mode, it is illuminated with a fixed light color and light that changes in brightness, so the shade of colored muddy water that emits and emits light with a fixed light color can be changed slightly, and an illusion that has never existed before It is possible to take a more relaxed bath by soaking in bath water that emits light with a natural color.
