JP7383930B2 - Wall-mounted lighting devices for bathrooms and bathrooms - Google Patents

Description

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

In recent years, LEDs have been increasingly used as light sources for bathroom lighting devices. However, compared to incandescent light bulbs and fluorescent lights, LEDs have stronger directionality and a narrower irradiation range. Therefore, if you place an LED lighting fixture on the wall in front of the center of the washing area, which is the conventional mounting location for lighting fixtures, the light distribution will be stronger towards the front of the LED lighting fixture, and it will be easier to install the LED lighting fixture on the work surface directly below the lighting fixture. Washing areas tend to lack brightness. There is also the problem of discomfort due to glare from the front of the LED lighting equipment.
In order to solve these problems, a bathroom lighting device has been proposed that includes a metal reflector that has a reflective piece that reflects the emitted light of an LED arranged on a substrate toward the floor of the bathroom (Patent Document 1).

JP2016-149286A

However, even in the lighting device of Patent Document 1, the bather is irradiated with light from the front, which may make the bather feel uncomfortable due to the strong directivity of the LEDs. For example, since showering in a standing position is done in close proximity to a lighting device, glare from the front makes the user uncomfortable.
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bathroom and a bathroom wall-mounted lighting device that can provide irradiated light that makes the user feel comfortable while using a highly directional LED as a light source.

In order to solve the above problems, the bathroom of the present invention includes a washing area floor, a bathtub installed next to the washing area floor, and a plurality of wall materials installed around the washing area floor and/or the bathtub. , a ceiling installed at the upper end of the wall material, of the plurality of wall materials, the wall material installed at a position adjacent to both the bathtub and the washing area is provided with a counter in front thereof. and a faucet device installed therein; further, an LED as a light source is built-in above the faucet device on the front surface of the first wall material; A lighting device is installed that includes a first light-transmitting surface and a second light-transmitting surface that irradiates light emitted by the LED to the outside, and the light that has passed through the first light-transmitting surface is irradiated toward the ceiling, The bathroom is characterized in that the light reflected from the surface of the ceiling illuminates the entire bathroom, and the light transmitted through the second light-transmitting surface directly illuminates the counter and faucet device.

According to this, the entire bathroom is illuminated by light transmitted from the first light-transmitting surface of the lighting device and reflected from the ceiling of the bathroom. When trying to illuminate the entire bathroom from the bathroom wall using highly directional LEDs, glare will occur in front of the lighting device if the lighting device directly illuminates the entire bathroom like a conventional lighting device. This makes bathers feel uncomfortable. However, in the present invention, the light emitted from the first light-transmitting surface on the top 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 uncomfortable due to glare.
Further, the counter and faucet device where people perform tasks such as washing their head and body or shaving are directly illuminated by the light transmitted from the second transparent surface. The light emitted from the first transparent surface and reflected on the ceiling illuminates the area behind the bather in front of the counter, so it is not possible to brightly illuminate the counter or faucet equipment. Since it is irradiated with light from the second light-transmitting surface, you can wash your body or hair while keeping your hands bright.

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

According to this, the counter and faucet device are illuminated with a relatively small amount of light from the second transparent surface. Therefore, the light and dark lines created on the washing area floor or counter due to the shadow of the counter or the shadow of the faucet device due to the light irradiated from the second transparent surface towards the counter or faucet device can be reduced. Not only will you feel less uncomfortable, but it will not interfere with your work at your feet or hands.

Further, in the lighting device, a side surface connecting the first light-transmitting surface and the second light-transmitting surface may be a non-light-transmitting surface.

According to this, it is possible to prevent the light reflected within the lighting device from being irradiated towards the bather from the front, which is a part of the side of the lighting device, making the bather feel even more uncomfortable. Never.

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

According to this, the light irradiated onto the ceiling of the bathroom from the first transparent surface can be more appropriately diffused throughout the bathroom, so it is possible to suppress the formation of darkness in the corners of the bathroom. , it becomes possible to provide a bathroom space with comfortable illumination.

Further, the bathroom wall-mounted lighting device of the present invention includes a substrate, an LED mounted on the substrate, and an outer shell housing the substrate and the LED, and the outer shell has the LED on its upper and lower surfaces. It has a first light-transmitting surface and a second light-transmitting surface that irradiate the emitted light to the outside, and further has a side surface as a non-light-transmitting surface, and the light transmitted through the first light-transmitting surface is directed above the outer shell. The light that is irradiated toward the outer shell and transmitted through the second light-transmitting surface is irradiated toward the lower part of the outer shell.

According to this, the entire bathroom is illuminated by light transmitted from the first light-transmitting surface of the lighting device and reflected from the ceiling of the bathroom. When trying to illuminate the entire bathroom from the bathroom wall using highly directional LEDs, glare will occur in front of the lighting device if the lighting device directly illuminates the entire bathroom like a conventional lighting device. This makes bathers feel uncomfortable. However, in the present invention, the light emitted from the first light-transmitting surface on the top 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 uncomfortable due to glare.
Further, the counter and faucet device where people perform tasks such as washing their head and body or shaving are directly illuminated by the light transmitted from the second transparent surface. The light emitted from the first transparent surface and reflected on the ceiling cannot brightly illuminate the counter or faucet device, but the counter or faucet device is illuminated by the light from the second transparent surface. You can wash your body or hair while keeping your hands bright.

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

According to this, a relatively small amount of light is irradiated downward from the lighting device from the second light-transmitting surface. Therefore, the light and dark lines created on the washing area floor or counter due to the shadow of the counter or the shadow of the faucet device due to the light irradiated from the second transparent surface towards the counter or faucet device can be reduced. Not only will you feel less uncomfortable, but it will not interfere with your work at your feet or hands.

According to the present invention, it is possible to provide a bathroom and a bathroom wall-mounted lighting device that can provide illumination light that makes the user feel comfortable while using a highly directional LED as a light source.

Embodiments of the present invention will be described below with reference to the drawings. Note that in each drawing, similar components are denoted by the same reference numerals, and detailed explanations are omitted as appropriate.
FIG. 1 is a diagram showing a bathroom according to an embodiment of the present invention.
In the bathroom A, a washing area floor 100 and a bathtub 110 are arranged adjacent to each other, and a wall material 120 and a door frame 130 are installed to surround the washing area floor 100 and the bathtub 110. A ceiling 140 is installed. This ceiling 140 is embossed and has fine irregularities formed on its surface. These fine irregularities function as a light diffusion surface that diffuses light emitted toward the ceiling from a lighting device described later.
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 (first wall material 121) facing the washing area floor 100.
The wall-mounted lighting device 190 has transparent surfaces 192 and 193 formed on its upper surface 191a and lower surface 191b. Light emitted from a transparent surface (first transparent 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 light-transmitting surface (second light-transmitting surface) 193 on the lower surface of the wall-mounted lighting device 190 illuminates the faucet device 160 and the washbasin counter 150. This wall-mounted lighting device 190 is attached to the first wall material 121 with screws.
Note that a shower hose 161 and a shower head 162 are attached to the faucet device 160, and the shower head 162 is hung on a shower hanger 170.

Next, the wall-mounted lighting device 190 will be explained.
FIG. 2 is a perspective view showing a wall-mounted lighting device according to an embodiment of the present invention, and FIG. 3 is a schematic vertical sectional view showing the wall-mounted lighting device.
This wall-mounted lighting device 190 has an upper surface 191a, a lower surface 191b, side surfaces (front surface 191c, left side surface 191d, right side surface 191e) that connect the upper surface 191a and the lower surface 191b, and an attachment part to the first wall material 121. The outer shell 191 includes a rear surface 191f and a rear surface 191f. A substrate 194 is housed inside the outer shell 191. LEDs 195 are mounted on the upper and lower surfaces of the substrate 194. The LED 195 receives power from an electric wiring (not shown) and irradiates light onto a predetermined range. Further, 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 light-transmitting surface 192, which is one of the above-mentioned light-transmitting surfaces, and the lower surface 191b is provided with a second light-transmitting surface 193. The light emitted by the LED 195 passes through these transparent surfaces 192 and 193 and illuminates the outside of the wall-mounted lighting device 190. On the other hand, the front surface 191c, left side surface 191d, and right side surface 191e of the outer shell 191 are made into light shielding portions 196 that are non-transparent surfaces that do not transmit the light emitted by the LEDs 195.

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

Further, this wall-mounted lighting device 190 is set so that the amount of light emitted from the second light-transmitting surface 193 is smaller than the amount of light emitted from the first light-transmitting surface 192.
This amount of light is set by adjusting the number and type of LEDs 195 and the total amount of 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 diagram showing how the bathroom 100 is illuminated by this wall-mounted lighting device 190.
In a conventional bathroom, an equal amount of light is emitted in all directions from the top, bottom, and side surfaces (front, left side, and right side) of a lighting device 300 that is installed on the wall and includes a built-in LED. 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 irradiated downward hits the faucet device 160 and the washbasin counter 150 and creates a dark shadow below them, resulting in a dark and dark line at the boundary of the shadow, creating darkness at your feet and hands. I can feel it.
In contrast, in the bathroom of the present invention, the wall-mounted lighting device 190 emits light from the first light-transmitting surface 192 on the upper surface 191a and the second light-transmitting 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. In addition, the faucet device 160 and washbasin counter 150 used for tasks such as washing the head and body or shaving are directly illuminated by the light emitted from the second transparent surface 193. The light emitted from the first transparent surface 192 and reflected by the ceiling 140 illuminates the area behind the bather in front of the washbasin counter 150, so that the faucet device 160 and the washbasin counter 150 are brightly irradiated. However, since the faucet device 160 and the washbasin counter 150 are illuminated with light from the second transparent surface 193, it is possible to wash the body or hair while keeping the area brightly lit. Furthermore, the amount of light emitted from the second transparent surface 193 is smaller than that from the upper surface 191a. Therefore, the bright and dark lines formed by the shadows created by the faucet device 160 and the washbasin counter 150 can be made thinner than in the past, making it less likely that darkness will be perceived at the feet or hands.
Further, no light is 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 and reflected inside the wall-mounted lighting device 190 is not irradiated horizontally from the side surface of the wall-mounted lighting device 190. Therefore, no glare is generated in front of the wall-mounted lighting device 190, and the bather who stands up is less likely to feel the light from the wall-mounted lighting device 190 as dazzling and therefore less likely to feel uncomfortable.

Further, the amount of light emitted from the first light-transmitting surface 192 is set to be larger than the amount of light emitted from the second light-transmitting surface 193. In other words, the amount of light emitted from the second light-transmitting surface 193 is set to be smaller than the amount of light emitted from the first light-transmitting surface 192. Therefore, the shadow of the washbasin counter 150 or the shadow of the faucet device 160 is projected onto the washroom floor 110 or the washbasin counter 150 by the light irradiated from the second transparent surface 193 toward the washbasin counter 150 or the faucet device 160. It is possible to thin out the bright and dark lines that are created. Therefore, it becomes difficult to feel dark or uncomfortable, and it does not interfere with the work underfoot or at hand.

Next, a modification of this embodiment will be shown.
FIG. 5 is a schematic cross-sectional view showing a modification 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. Part of the light emitted by the LED 295 is irradiated from the first light-transmitting surface 292, and part of the light is reflected inside the wall-mounted lighting device 290 and travels below the board 294 through the gap between the outer shell 291 and the board 294. The second light-transmitting surface 293 is irradiated with a smaller amount of light than the first light-transmitting surface 292 .
According to this, light can be suitably irradiated from the upper surface 291a and lower surface 291b of the wall-mounted lighting device 290 without mounting the LED 295 on both the upper and lower surfaces of the board 294.

The embodiments of the present invention have been described above. However, the invention is not limited to these descriptions. Appropriate design changes made by those skilled in the art with respect to the above-described embodiments are also included within the scope of the present invention as long as the effects of the present invention are achieved.
For example, instead of using the front, left side, and right side of the outer shell of the wall-mounted lighting device as light shielding parts, a light reduction part may be used to greatly reduce the amount of light and irradiate the outside.
Alternatively, the board on which the LED is mounted can be tilted so that the end on the indoor side faces downward, and light can be irradiated from the second light-transmitting surface toward the first wall material side.
Furthermore, the amount of light emitted from the first light-transmitting surface and the amount of light emitted from the second light-transmitting surface can be adjusted respectively.
Furthermore, the elements of each of the embodiments described above can be combined to the extent technically possible, and combinations of these are also included within the scope of the present invention as long as they include the features of the present invention.
