DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a lighting device installed in a bathroom.

[0002]

2. Description of the Related Art In a lighting apparatus installed in a bathroom, a light source and the like are covered without gaps by gloves or the like in order to eliminate the influence of water vapor in the bathroom. In this case, the glove is colored milky white or the like so as to diffuse the light so that the glove does not enter the eyes and irradiate soft light into the bathroom.

[0003]

However, the colored glove also functions as a filter that absorbs a part of the light emitted from the light source, and changes the spectral distribution of the transmitted light. For this reason, in such a lighting device, there was a problem that the appearance of the color of the illuminated object was not natural.

For example, a solid line in FIG. 6 shows a spectral distribution of light emitted from an incandescent lamp (hereinafter referred to as an incandescent lamp light a), and a broken line d in FIG.
Shows the spectral distribution of transmitted light d after passing through the milky white hemispherical globe. From FIG. 6, for the transmitted light d, for example, light having a wavelength of 380 to 410 nm is cut (absorbed) by the glove, so that the glove shines reddish and illuminates the bathroom with a reddish feeling.

[0005] Therefore, for example, even if the bathroom is finished with a white color, by using such a lighting device,
There is a problem that the color tone is not sufficient.

In such a case, if a daylight lamp in which light in the red wavelength portion is partially cut off is used as a light source, the transmitted light from the globe approaches the incandescent light a.
This daylight lamp has a large decrease in illuminance for output,
In addition, there is a disadvantage that the price is high.

[0007] In view of the above, it is an object of the present invention to provide an illuminating device that can illuminate a bathroom with a natural color state without causing a bather to feel glare.

[0008]

According to a first aspect of the present invention, in a lighting device installed in a bathroom, a translucent portion of a globe covering a light source is constituted by a colored portion and a transparent portion .
The colored part that diffuses the light strongly
Installed on the front part along the lighting device mounting wall and the transparent part around the front part
This is provided on the side surface of the vehicle .

According to the present invention, the illuminating device separates the transmitted light from the colored portion of the glove that strongly absorbs light of the specific wavelength and the transmitted light from the transparent portion of the glove that does not strongly absorb light of the specific wavelength. Irradiate in bathroom. For this reason, the influence of the colored portion of the glove is reduced, and the bather can see the inside of the bathroom through light having a spectral distribution close to the light emitted from the light source. In this case, the coloring part of the glove can prevent the bather from feeling glare. In the present invention,
The front part of the glove that is easy for bathers to see is a coloring part
The transparent side is made difficult for bathers to see.
Gloves without giving bathers a glare
Of the transparent portion can be increased.

[0010] The invention of claim 2, wherein the invention, claim
In the case of the invention described in 1 , the side surface portion of the glove is grained.

In the present invention, since the side surface of the glove is subjected to graining, the light transmitted through the side surface is also diffused, and the glare caused by the transmitted light is sufficiently reduced.

An opening 20c is formed in the center, and a ring-shaped protrusion 20d for supporting the socket 21 is formed on the inner surface around the opening 20c. The mounting portion 20B has a holding groove 20e for the glove packing 25 formed on the outer peripheral end, and fixed protrusions 20f for fixing the glove 23 are formed at a predetermined pitch on the inner surface side.

The pedestal 20 presses the mounting packing 26 in the holding groove 20a against the front wall W so that the base 20
A is attached to the front wall W by screwing the mounting screw 27 inserted into A into the front wall W side.

As shown in FIGS. 2 and 4, the socket 21 has a flange 21a at the front end of the cylindrical body. After the rear end of the socket 21 is inserted into the opening 20c of the pedestal 20, the flange 21a Screw 28 from the side
It is attached to the pedestal 20 by screwing it into the 0d side. In this case, the socket 21 is positioned such that the rear end protrudes between the wall panel 2 and the wall surface of the building via the opening W1 of the front wall W. A power supply cord E is connected to the socket 21.

The light source 22 is composed of, for example, a 60 W incandescent lamp. As shown in FIGS. 2 and 4, the light source 22 has a base (not shown) screwed into the front end side recess 21 b of the socket 21, and the base 20 A of the base 20.
Is attached to the socket 21 in a state protruding forward from the front wall W. The light emitting portion of the light source 22 is positioned substantially at the center of the globe 23.

The globe 23 covers around the light source 22,
The function of preventing the light source 22 and the socket 21 from being affected by the water vapor in the bathroom U, and the function of diffusing the light from the light source 22 so that a bather does not feel glare due to the light from the light source 22. In addition, it has a function of irradiating the bathroom U with appropriate soft light.

As shown in FIG. 2, the globe 23 has a convex spherical front portion 23A as a colored portion, which is disposed along a front wall W which is a mounting wall of the lighting device 13.
A substantially cylindrical side surface portion 23B as a transparent portion having an outer surface formed in a wavy shape, and a rear end side of the side surface portion 23B. A perforated disk-shaped rear surface portion 23C as a transparent portion,
And a small cylindrical mounting portion 23D arranged on the inner end side of the rear surface portion 23C.

The front portion 23A is made of, for example, a resin material colored in milky white and has a side portion 2A.
The 3B, the rear surface portion 23C, and the mounting portion 23D are integrally and transparently formed of, for example, a resin material. Then, the front surface portion 23A and the side surface portion 23 formed integrally are formed.
B, the rear surface portion 23C, and the mounting portion 23D are integrally joined by, for example, ultrasonic welding. The front part 23A, the side part 23B, and the rear part 23C of the glove 23
Is a light transmitting part.

The transparent side portions 23B and the like are subjected to a graining treatment (a treatment for generating small irregularities on the surface) on the inner surface thereof so that light transmitted therethrough does not directly enter a bather's eyes and cause glare. It has been subjected. However, the lower side of the side surface portion 23B, that is, the lower portion 23a of the side surface portion 23B located in an angle region of 40 degrees from the center of the side surface portion 23B, is not subjected to the graining process.

As shown in FIG. 2, a plurality of pressure projections 23b are formed on the outer surface of the mounting portion 23D so as to engage with the fixing projections 20f of the pedestal 20 and press the globe 23 toward the pedestal 20. I have. The glove 23 is attached to the pedestal 20 by inserting the attachment portion 23D into the attachment portion 20B of the pedestal 20 and then rotating it by a predetermined angle to engage the fixed projection 20f and the pressure projection 23b. Can be
In this case, the rear surface portion 23C of the glove 23 presses the glove packing 25 side of the pedestal 20 side.
The gap between 3 and pedestal 20 is sealed.

The reflection plate 24 reflects light from the light source 22 downward while slightly facing forward, and is made of a thin metal plate. As shown in FIG. 2, the reflection plate 24 is attached to the pedestal 20 by screws 28 in a state where the front end side is inclined upward along a guide projection 20b disposed above the ring-shaped projection 20d of the pedestal 20. Have been. Note that the front side of the reflection plate 24 is curved in a downwardly concave shape along the light source 22.

Next, the operation and effect of the lighting device 13 will be described. The light emitted from the light source 22 passes through a glove 23 disposed around the light source 22 and is applied to the interior of the bathroom U, and maintains the interior of the bathroom U at a brightness suitable for bathing. In this case, since the reflecting plate 24 is disposed above the light source 22, the light emitted from the light source 22 to the ceiling panel 3 side of the bathroom U is reflected by the reflecting plate 24, The light is radiated to the floor pan 1 side through 23a and the like. Therefore, in this bathroom U, there is a bather and the floor pan 1 side that needs to be brightened is illuminated more brightly than the ceiling panel 3 side that does not need much brightness, and the illumination device 13 is appropriately illuminated. You.

In this lighting device 13, the globe 2
Since the side surface portion 23B of 3 is transparent, light absorption by the globe 23 is small, and efficient illumination is performed. In particular, since the lower part 23a of the side part 23B is not subjected to the graining treatment and has a high light transmittance, the periphery of the washstand 6 is illuminated brightly through the lower part 23a. Of course, the interior of the bathroom U is irradiated with soft light via the front part 23A of the glove 23 colored milky white.

Further, in this lighting device 13, the front part 23A of the glove 23, which is most noticeable to the bather, is colored milky and sufficiently diffuses light, and the side part 23B of the glove 23 is also embossed. The bather does not feel the glare from the light source 22 because it is treated and diffuses the light to some extent. In addition, the side part 2 of the glove 23
Although the lower part 23a of 3B is not subjected to the graining treatment, since the bather rarely looks directly at this part, the bather does not feel glare through this lower part 23a.

Since the light source 22 is constituted by an incandescent lamp, as shown by the solid line in FIG.
The incandescent light a emitted from the light source 2 is in the visible region (for example, wavelength 3
It has a spectral distribution close to natural light at a wavelength of 80 nm to a wavelength of 760 nm. Therefore, when an object is viewed through the light source 22, the natural color of the object can be recognized.

On the other hand, since the light source 22 is covered with the globe 23, the light from the light source 22 is radiated into the bathroom U via the globe 23. In this case, since the front part 23A of the glove 23 colored milky white has a property of strongly absorbing light in a wavelength region of about 380 to 410 nm, as shown by a broken line in FIG. Light b is
In the visible region, a spectral distribution in which light having a wavelength of 380 to 410 nm (purple spectrum portion) is missing is shown. Therefore, in the transmitted light b, the red spectrum portion becomes relatively strong, and when the object is viewed through the transmitted light b, the object appears reddish and does not show a natural color.

However, the side surface 23B of the globe 23
Is transparent, the transmitted light c of the side surface portion 23B does not strongly absorb light of a specific wavelength, and exhibits almost the same spectral distribution as the light source 22 as shown by a chain line in FIG. . Therefore, when the object is viewed through the transmitted light c of the side surface portion 23B, almost the natural color of the object can be recognized.

That is, in the illuminating device 13, light having a part of missing wavelength is transmitted from the front portion 23 A of the globe 23, but light similar to the incandescent lamp light a is transmitted from the side portion 23 B of the globe 23. Therefore, the influence of the front portion 23A of the glove 23 is reduced, and the bather can see the object in the same state as seeing the object through the incandescent light a. Therefore, even when the floor pan 1, the wall panel 2, the ceiling panel 3, the bathtub 5, and the like in the bathroom U are finished in, for example, a white color tone, the bather can use the natural color through the lighting device 13. (The color of the design) can be recognized. Also,
In the lighting device 13, it is not necessary to use an expensive daylight lamp as the light source 22, which has a large decrease in illuminance.

Here, if the area of the transparent part is increased as compared with the area of the milky white part of the glove 23, the above tendency is increased, but it is necessary to prevent the bather from feeling glare. The ratio of the transparent portion of the glove 23 has its own limit.

The light source 22 may be of any type as long as it has a spectral distribution close to natural light in the visible region (for example, a halogen lamp).

[0037]

Since the present invention is configured as described above, it has the following effects.

According to the first aspect of the present invention,

Since there is provided in part, through the colored portion of the glove and the transparent portion, without having to feel the glare to the bather, it is possible to illuminate the inside of the bathroom in natural color state, glove
Of the transparent portion can be increased .

According to the second aspect of the present invention,
In the case of the first aspect of the present invention, since the side surface of the glove is subjected to the graining process, the bather can hardly feel the glare even by the transmitted light of the side surface.
