However, the lighting mode in which the first lighting unit 21, the second lighting unit 22, and the fourth lighting unit 24 are turned off and the third lighting unit 23 is turned on is not limited to the fluctuation pattern lighting mode. Alternatively, a lighting mode with a constant luminous flux value and color temperature may be used.

In the first fluctuation mode, the control unit 30 sets the color temperature of the light emitted from the third illumination unit 23 to approximately 2000K (for example, 1900K or more and 2200K or less).

In addition, the third illumination unit 23 can directly irradiate light toward the floor 42 of the washing area. Therefore, in the first fluctuation mode and the second fluctuation mode, the fluctuation pattern light emitted from the third illumination unit 23 is reflected on the floor 42 of the washing area, and effects the interior of the bathroom BR. As a result, it is possible to provide the bather with a higher relaxation effect.

In addition, in the first fluctuation mode (third lighting mode), the first illumination section 21 and the second illumination section 22 do not necessarily have to be turned off. In the first fluctuation mode, the luminous flux value of the light emitted from each of the first illumination unit 21 and the second illumination unit 22 is made smaller than the luminous flux value of the light emitted from the third illumination unit 23, and the third illumination unit 23 may be turned on.

In this way, the control unit 30 controls the light in the vertical direction in the bathroom BR by using a plurality of lighting modes including the bright mode, the medium mode, the dark mode, the meditation mode, the ultra-meditation mode, the first fluctuation mode, and the second fluctuation mode. change the center of gravity of In other words, the control unit 30 changes the vertical position of the portion with the highest luminous flux value in the bathroom BR in a plurality of lighting modes.

Humans synchronize with the rhythm of natural light from the sun, are active during the day when the sun is high, calm down from dusk when the sun is low until the sun sets, and are active at night. It is known that the position of light has an effect on human psychology, such as resting and relaxing. The same is true for indoor lighting. For example, when you want to relax, you can create a relaxing and relaxing space by dimming the ceiling lighting in the room and turning on the low lighting. Conversely, during periods of high activity or situations that require a sense of tension, lighting from top to bottom with high lighting can create a refreshing space.

In the bathroom unit 10, the control unit 30 changes the center of gravity of light in the vertical direction in the bathroom BR using a plurality of lighting modes. As a result, it is possible to realize a bathing environment such as a relaxing effect and a refreshing effect desired by the bather. Therefore, the bather's refreshing effect and relaxing effect can be further improved.

Further, in the bathroom unit 10, the first illumination section 21, the second illumination section 22, the third illumination section 23, and the fourth illumination section 24 have a plurality of light sources with different color temperatures, and the control section 30 includes a plurality of light sources having different color temperatures. The color temperature of the light emitted from each of the first lighting unit 21, the second lighting unit 22, the third lighting unit 23, and the fourth lighting unit 24 is changed according to the lighting mode. This enables reproducibility of color temperature changes such as during the day when the actual sun is high (high illuminance/high color temperature), at dusk when the sun is low (low illuminance/low color temperature), and between the two. High simulation is possible. For this reason, for example, it is possible to realize a space in which deeper refreshing effect and relaxing effect can be obtained according to the preference of the bather.

In addition, the plurality of lighting modes set in the control unit 30 are not necessarily limited to the above. The plurality of lighting modes may have more lighting modes in which lighting states of the lighting units 21 to 24 are changed. If the plurality of lighting modes has at least three lighting modes: a first lighting mode (e.g., bright mode), a second lighting mode (e.g., meditation mode), and a third lighting mode (e.g., first fluctuation mode) good.

As shown in FIG. 3, the bathroom unit 10 further comprises a switch 32 and a lighting switch 34, for example. Switch 32 is electrically connected to control unit 30 . The switch 32 is attached, for example, to the wall surface outside the bathroom BR (for example, the wall surface of the dressing room) or the bathroom wall 44a inside the bathroom BR. The switch 32 instructs the control unit 30 to switch between lighting and extinguishing of the lighting units 21 to 24 . The control unit 30 lights each of the lighting units 21 to 24 according to the lighting instruction from the switch 32 . For example, the control unit 30 turns on each of the illumination units 21 to 24 in the bright mode in response to a lighting instruction from the switch 32 . In addition, the control unit 30 turns off each of the illumination units 21 to 24 in response to a turn-off instruction from the switch 32 .

The lighting switch 34 is electrically connected to the controller 30 . The lighting switch 34 is attached to the bathroom wall 44a in the bathroom BR or the inner wall of the bathtub 40, for example. The lighting switch 34 is a switch for switching between a plurality of lighting modes.

The control unit 30 sequentially switches a plurality of lighting modes in order from the higher side of at least one of the luminous flux value and the color temperature, or from the lower side of at least one of the luminous flux value and the color temperature, according to the operation of the lighting switch 34. .

The lighting switch 34 has a first operating section for instructing switching to the dark direction, a second operating section for instructing switching to the bright direction, and a third operating section for instructing to stop dimming control. and

For example, according to the operation of the first operation unit of the lighting switch 34, the control unit 30 selects a light mode, a medium mode, a dark mode, a meditation mode, a super meditation mode, a first fluctuation mode, and a second fluctuation mode in this order. sequentially switch the lighting modes.

For example, the control unit 30 can switch between the second fluctuation mode, the first fluctuation mode, the super-meditation mode, the meditation mode, the dark mode, the medium mode, and the bright mode in the opposite manner to the above in accordance with the operation of the second operation section of the lighting switch 34 . A plurality of lighting modes are sequentially switched in mode order.

For example, when the third operation portion of the illumination switch 34 is operated, the control unit 30 switches from the current illumination mode to the bright mode regardless of which one of the plurality of illumination modes is set. As a result, for example, when the user wants to brighten the room by leaving the bathroom BR from the state set to the second fluctuation mode or the like, it is possible to suppress the trouble of having to operate the second operation unit many times. .
