Description

The present invention relates to a bathroom equipped with a lighting device and a lighting device attached to a wall surface of the bathroom.

In recent years, LEDs have come to be widely used as a light source for bathroom lighting devices. However, compared to incandescent lamps and fluorescent lamps, LEDs have stronger directivity and a narrower irradiation range. Therefore, if the LED lighting fixture is placed on the wall surface in front of the center of the washing place, which is the mounting position of the lighting fixture so far, the light distribution to the front side of the LED lighting fixture becomes stronger, which is the work surface directly under the lighting fixture. The brightness of the washing area tends to be insufficient. There is also a problem that glare on the front surface of the LED lighting fixture causes discomfort.
In order to solve these problems, a bathroom lighting device including a metal reflector having a reflecting piece that reflects the emitted light of an LED arranged on a substrate toward the floor of the bathroom has been proposed (Patent Document). 1).

Japanese Unexamined Patent Publication No. 2016-149286

However, even in the lighting device of Patent Document 1, since the bather is irradiated with light from the front, he / she may feel uncomfortable due to the strong directivity of the LED. For example, since the shower bath in a standing posture is performed at a position close to the lighting device, glare on the front portion causes discomfort.
Therefore, an object of the present invention is to provide a bathroom in which an irradiation light that can be comfortably felt by the user can be obtained while using an LED having strong directivity as a light source, and a wall-mounted lighting device for the bathroom.

In order to solve the above-mentioned problems, the bathroom of the present invention includes a washroom floor, a bathtub installed next to the washroom floor, and a plurality of wall materials installed around the washroom floor and / or the bathtub. In a bathroom provided with a ceiling installed at the upper end of the wall material, a wall material installed at a position adjacent to both the bathtub and the washing place among the plurality of wall materials is countered in front of the wall material. And a first wall material to which a faucet device is installed, and further, an LED as a light source is built in the front surface of the first wall material above the faucet device, and the upper surface and the lower surface are described, respectively. A lighting device provided with a first translucent surface and a second transmissive surface for irradiating the light emitted by the LED to the outside is installed, and the light transmitted through the first transmissive surface is irradiated toward the ceiling. The light reflected on the surface of the ceiling illuminates the entire bathroom, and the light transmitted through the second translucent surface directly irradiates the counter and the faucet device.

According to this, the entire bathroom is illuminated by the light transmitted from the first translucent surface of the illuminating device and reflected by the ceiling of the bathroom. When trying to illuminate the entire bathroom from the wall of the bathroom using a highly directional LED, if the entire bathroom is illuminated directly from the lighting device like a conventional lighting device, glare will occur in front of the lighting device. The bather feels uncomfortable because of this. However, in the present invention, the light emitted from the first translucent surface on the upper surface of the lighting device toward the ceiling of the bathroom is reflected by the ceiling and is irradiated to the entire bathroom. Therefore, the bather can comfortably take a bath without feeling discomfort due to glare.
In addition, counters and faucet devices that perform tasks such as washing the head and body and shaving are directly illuminated by the light transmitted from the second translucent surface. The light emitted from the first translucent surface and reflected on the ceiling illuminates behind the bather in front of the counter, so the counter and faucet device cannot be illuminated brightly, but the counter and faucet device cannot be illuminated brightly. Is irradiated with light from the second translucent surface, so it is possible to brighten the hands and wash the body and hair.

Further, the amount of light emitted from the first translucent surface can be set to be larger than the amount of light emitted from the second translucent surface.

According to this, the counter and the faucet device are illuminated with a relatively small amount of light from the second translucent surface. Therefore, the light and dark lines created on the floor of the washing place or on the counter can be thinned by the shadow of the counter due to the light radiated from the second translucent surface toward the counter or the faucet device or the shadow of the faucet device. The faucet is less likely to be felt and the work at the feet and hands is not hindered.

Further, in the lighting device, the side surface connecting the first translucent surface and the second translucent surface can be a non-transmissive surface.

According to this, it is possible to prevent the light reflected in the lighting device from being irradiated from the front, which is a part of the side surface of the lighting device, toward the bather, so that the bather feels even more uncomfortable. Never.

Furthermore, the ceiling may be provided with a light diffusing surface on its surface.

According to this, the light radiated from the first translucent surface to the ceiling of the bathroom can be more preferably diffused throughout the bathroom, so that it is possible to suppress the generation of darkness in the corners of the bathroom. , It is possible to provide a bathroom space with comfortable illuminance.

Further, the wall-mounted lighting device for a bathroom of the present invention includes a substrate, an LED mounted on the substrate, and an outer shell incorporating the substrate and the LED, and the outer shell has the LED on the upper surface and the lower surface thereof. It has a first translucent surface and a second translucent surface that irradiate the emitted light to the outside, and further, the side surface is a non-transmissive surface, and the light transmitted through the first transmissive surface is above the outer shell. The light emitted toward the surface and transmitted through the second translucent surface is emitted toward the lower side of the outer shell.

According to this, the entire bathroom is illuminated by the light transmitted from the first translucent surface of the illuminating device and reflected by the ceiling of the bathroom. When trying to illuminate the entire bathroom from the wall of the bathroom using a highly directional LED, if the entire bathroom is illuminated directly from the lighting device like a conventional lighting device, glare will occur in front of the lighting device. The bather feels uncomfortable because of this. However, in the present invention, the light emitted from the first translucent surface on the upper surface of the lighting device toward the ceiling of the bathroom is reflected by the ceiling and is irradiated to the entire bathroom. Therefore, the bather can comfortably take a bath without feeling discomfort due to glare.
In addition, counters and faucet devices that perform tasks such as washing the head and body and shaving are directly illuminated by the light transmitted from the second translucent surface. The light emitted from the first translucent surface and reflected on the ceiling cannot illuminate the counter or faucet device brightly, but the counter or faucet device is irradiated with the light from the second transmissive surface. You can wash your body and hair by brightening your hands.

Further, the amount of light emitted from the first translucent surface can be set to be larger than the amount of light emitted from the second translucent surface.

According to this, a relatively small amount of light is emitted from the second translucent surface toward the lower side of the illuminating device. Therefore, the light and dark lines created on the floor of the washing place or on the counter can be thinned by the shadow of the counter due to the light radiated from the second translucent surface toward the counter or the faucet device or the shadow of the faucet device. The faucet is less likely to be felt and the work at the feet and hands is not hindered.

According to the present invention, it is possible to provide a bathroom in which an irradiation light that can be comfortably felt by the user can be obtained and a wall-mounted lighting device for the bathroom while using an LED having strong directivity as a light source.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, similar components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate.
FIG. 1 is a diagram showing a bathroom according to an embodiment of the present invention.
In the bathroom A, the washroom floor 100 and the bathtub 110 are arranged adjacent to each other, and the wall material 120 and the door frame 130 are installed so as to surround the washroom floor 100 and the bathtub 110, and the wall material 120 and the door frame 130 are at the upper ends of the wall material 120 and the door frame 130. The ceiling 140 is installed. The ceiling 140 is embossed, and fine irregularities are formed on the surface thereof. These fine irregularities function as a light diffusing surface that diffuses the light emitted from the lighting device described later toward the ceiling.
A washbasin counter 150, a faucet device 160, a shower hanger 170, a mirror 180, and a wall-mounted lighting device 190 are attached to one of the wall materials 120 facing the washing floor 100 (first wall material 121).
The wall-mounted lighting device 190 has transparent surfaces 192 and 193 formed on its upper surface 191a and lower surface 191b. The light emitted from the translucent surface (first translucent surface) 192 on the upper surface of the wall-mounted lighting device 190 is reflected by the ceiling 140 and illuminates the entire bathroom. Further, the light emitted from the translucent surface (second translucent surface) 193 on the lower surface of the wall-mounted lighting device 190 illuminates the faucet device 160 and the washbasin counter 150. The wall-mounted lighting device 190 is attached to the first wall material 121 by screwing.
A shower hose 161 and a shower head 162 are attached to the faucet device 160, and the shower head 162 is hooked on the shower hanger 170.

Next, the wall-mounted lighting device 190 will be described.
FIG. 2 is a perspective view showing the wall-mounted lighting device according to the embodiment of the present invention, and FIG. 3 is a schematic vertical sectional view showing the wall-mounted lighting device.
The wall-mounted lighting device 190 has a side surface (front surface 191c, left side surface 191d, right side surface 191e) connecting the upper surface 191a, the lower surface 191b, the upper surface 191a and the lower surface 191b, and an attachment portion to the first wall material 121. It is provided with an outer shell 191 including a back surface 191f and a back surface 191f. A substrate 194 is built in the outer shell 191. The LED 195 is mounted on the upper surface and the lower surface of the substrate 194. The LED 195 receives electric power by an electric wiring (not shown) and irradiates a predetermined range with light. Further, the power supply to the LED 195 is controlled by a control unit (not shown) installed behind the ceiling 140.
The upper surface 191a of the outer shell 191 is provided with a first translucent surface 192, which is one of the above-mentioned translucent surfaces, and the lower surface 191b is provided with a second translucent surface 193. The light emitted by the LED 195 passes through these translucent surfaces 192 and 193 and illuminates the outside of the wall-mounted lighting device 190. On the other hand, the front surface 191c, the left side surface 191d, and the right side surface 191e of the outer shell 191 are light-shielding portions 196 which are non-transmissive surfaces that do not transmit the light emitted by the LED 195.

The wall-mounted lighting device 190 does not irradiate light from the side surfaces (front surface 191c, left side surface 191d, right side surface 191e) of the outer shell 191 but irradiates light only from the upper surface 191a and the lower surface 191b.

Further, the wall-mounted lighting device 190 is set so that the amount of light emitted from the second translucent surface 193 is smaller than the amount of light emitted from the first translucent surface 192.
This amount of light is set by adjusting the number and type of LEDs 195 and the total amount of electric power supplied to the LEDs 195. Alternatively, the light transmittance of the first light transmitting surface 192 may be set higher than the light transmittance of the second light transmitting surface 193.

FIG. 4 is a schematic schematic view showing a mode in which the bathroom 100 is illuminated by the wall-mounted lighting device 190.
In a conventional bathroom, the same amount of light is emitted from the upper surface, the lower surface, and the side surface (front surface, left side surface, right side surface) of the lighting device 300 having an LED built in the wall in all directions. Therefore, the bather who stands up may feel uncomfortable due to the glare generated in front of the lighting device 300. In addition, the light emitted downward hits the faucet device 160 and the washbasin counter 150, and creates a dark shadow below them. Therefore, a dark light / dark line is generated at the boundary of the shadow to add darkness to the feet and hands. I may feel it.
On the other hand, in the bathroom of the present invention, the wall-mounted lighting device 190 irradiates light from the first translucent surface 192 on the upper surface 191a and the second translucent surface 193 on the lower surface 191b. The light emitted from the upper surface 191a is diffused by the unevenness of the surface of the ceiling 140 and illuminates the entire bathroom 100. Further, the faucet device 160 and the washbasin counter 150 that perform operations such as washing the head and body and shaving the beard are directly illuminated by the light emitted from the second translucent surface 193. The light emitted from the first translucent surface 192 and reflected by the ceiling 140 irradiates the back of the bather in front of the washbasin counter 150, so that the faucet device 160 and the washbasin counter 150 are illuminated brightly. However, since the faucet device 160 and the washbasin counter 150 are irradiated with the light from the second translucent surface 193, it is possible to brighten the hands and wash the body and hair. Further, the amount of light emitted from the second translucent surface 193 is smaller than that of the upper surface 191a. Therefore, the light and dark lines formed by the shadows formed by the faucet device 160 and the washbasin counter 150 can be made thinner than before, so that it is difficult to feel the darkness at the feet and hands.
Light is not emitted from the side surfaces (front surface 191c, left side surface 191d, right side surface 191e) of the wall-mounted lighting device 190. More specifically, the light emitted by the LED 195 reflected inside the wall-mounted lighting device 190 is not emitted from the side surface of the wall-mounted lighting device 190 in the horizontal direction. Therefore, glare does not occur in the front surface of the wall-mounted lighting device 190, and the standing bather is less likely to feel the light of the wall-mounted lighting device 190 as dazzling and uncomfortable.

Further, the amount of light emitted from the first translucent surface 192 is set to be larger than the amount of light emitted from the second translucent surface 193. In other words, the amount of light emitted from the second translucent surface 193 is set to be smaller than the amount of light emitted from the first translucent surface 192. Therefore, the shadow of the washbasin counter 150 or the shadow of the faucet device 160 is cast on the washroom floor 110 or the washbasin counter 150 by the light emitted from the second translucent surface 193 toward the washbasin counter 150 and the faucet device 160. The light and dark lines created in can be thinned. Therefore, the darkness and discomfort are less likely to be felt, and the work at the feet and hands is not hindered.

Next, a modified example of this embodiment is shown.
FIG. 5 is a schematic cross-sectional view showing a modified example of the wall-mounted lighting device.
In the wall-mounted lighting device 290 of this modification, the LED 295 is mounted only on the upper surface of the substrate 294. Then, a part of the light emitted by the LED 295 is emitted from the first translucent surface 292, and a part of the light is reflected inside the wall-mounted lighting device 290 and goes to the lower part of the substrate 294 through the gap between the outer shell 291 and the substrate 294. It is irradiated from the second translucent surface 293 with a light amount smaller than that of the first translucent surface 292.
According to this, light can be suitably irradiated from the upper surface 291a and the lower surface 291b of the wall-mounted lighting device 290 without mounting the LEDs 295 on both the upper and lower surfaces of the substrate 294.

The embodiments of the present invention have been described above. However, the present invention is not limited to these descriptions. With respect to the above-described embodiment, those skilled in the art with appropriate design changes are also included in the scope of the present invention as long as the effects of the present invention are exhibited.
For example, instead of using the front surface, the left side surface, and the right side surface of the outer shell of the wall-mounted lighting device as the light-shielding portion, a dimming portion that greatly reduces the amount of light and irradiates the outside may be used.
It is also possible to incline the substrate on which the LED is mounted so that the end portion on the indoor side is downward, and irradiate the light from the second translucent surface toward the first wall material side.
Further, the amount of light emitted from the first translucent surface and the amount of light emitted from the second translucent surface can be adjusted respectively.
In addition, the elements included in each of the above-described embodiments can be combined as much as technically possible, and the combination thereof is also included in the scope of the present invention as long as the features of the present invention are included.
