Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device attached to a sanitary facility room such as a bathroom, a toilet, a washroom and a kitchen.

[0002]

2. Description of the Related Art In a conventional lighting device in which a light source is covered with a globe, the light is radiated to the outside of the globe almost uniformly. Therefore, when such an illuminating device is attached to, for example, a wall close to the ceiling of the bathroom, the illumination device irradiates the ceiling side and the floor side of the bathroom with light substantially equally. Therefore, in this bathroom, a phenomenon occurs in which the ceiling side closer to the lighting device is illuminated brightly by the lighting device than the floor side far from the lighting device.

[0003]

However, since there are bathers near the floor in the bathroom, it is desirable to make the floor side brighter than the ceiling side. Therefore, in the above-mentioned conventional lighting device, the lighting in the bathroom to which this is attached is
There was a problem that it was not always done properly.
For this reason, when such an illuminating device is used, there is a problem that it is necessary to unnecessarily increase the luminous intensity of the light source or increase the number of illuminating devices in order to secure the illuminance in a necessary place.

The above problem similarly occurs in a lighting device mounted in a sanitary facility room other than a bathroom, such as a toilet, a washroom, or a kitchen.

In view of the above points, an object of the present invention is to provide an illuminating device capable of performing appropriate illumination in a sanitary facility room without increasing the light intensity of the light source.

[0006]

According to a first aspect of the present invention, in a lighting device installed in a sanitary facility room, a reflector for converging light emitted from a light source to a required place is provided. Is.

According to a second aspect of the present invention, a pedestal with a socket attached to a wall near a ceiling of a sanitary facility room,
In a lighting device in which a light source is attached so as to project to the front of a wall, and a globe is attached to a pedestal with a socket so as to cover the light source, a socket from the light source is attached to the pedestal side with a socket behind the light source in the globe. The first reflector that reflects the light emitted to the pedestal side to the front side of the light source is provided, and the light emitted from the light source to the upper side of the light source is provided above the light source in the globe.
That is, a second reflector that reflects light is provided below the light source.

According to a third aspect of the present invention, in the case of the second aspect, the reflecting surface of the second reflector is curved concavely toward the light source side.

According to a fourth aspect of the present invention, in the case of the second aspect of the invention, the second reflector is mounted on the pedestal with a socket in a state where the second reflector can be rotated about the light source to change its position. It is installed.

According to a fifth aspect of the present invention, in the case of the second aspect, at least the lower side of the glove is
It is formed in a shape that refracts the light emitted from the light source toward the front side of the wall.

According to a sixth aspect of the present invention, in the case of the second aspect of the invention, the lower side of the globe is formed so as to have a higher light transmittance than other portions of the globe. .

[0012]

According to the first aspect of the present invention, the light emitted from the light source to the reflector side is reflected by the reflector and is condensed at a place where brightness is particularly required. Therefore, light can be effectively used in the sanitary facility room to which the lighting device is attached.

According to the second aspect of the present invention, the light emitted from the light source to the socket-side pedestal side behind the light source is
After being reflected to the front side of the light source by the first reflector, the light emitted to the upper side of the light source from the light source while being emitted to the sanitary facility room through the globe is also reflected by the second reflector. After being reflected to the lower side of the room, it is irradiated through the gloves into the sanitary facility room. Therefore, in the sanitary equipment room where this lighting device is installed, the light that was conventionally absorbed as heat on the pedestal side with a socket can be effectively used, and the brightness is increased accordingly, while the ceiling side is conventionally used. Part of the light that was illuminating too much is radiated to the floor side where people are, and the light is used effectively.

In the invention of claim 3 of the present invention, since the reflecting surface of the second reflector is formed in a concave shape toward the light source side, the light emitted above the light source is reflected by the second reflecting member. The light is reflected by the body so as to be condensed at one place, and a large amount is irradiated to the lower side of the light source.

In the invention according to claim 4 of the present invention, since the second reflector can be rotated around the light source to change its position, the light reflected by the second reflector is directly under the light source. You will be able to gather not only on the side but also where you need it, as needed. For example, the lower right side or the lower left side of the light source can be illuminated.

According to the fifth aspect of the present invention, the light radiated below the light source is not radiated into the sanitary facility room along the surface of the wall, but is refracted by the globe and the front side of the wall. Since the irradiation is directed toward the center of the sanitary equipment room, the sanitary equipment room is illuminated more effectively.

According to the invention of claim 6 of the present invention, since the light transmittance of the lower side of the glove is made higher than that of other portions, it is possible to easily increase the illuminance on the floor side of the sanitary facility room where a person is located. .

[0018]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 8 is an external perspective view of the inside of the bathroom to which the lighting device according to the embodiment of the present invention is attached.

In FIG. 8, on the floor surface in front of the front wall W1 of the bathroom R, a bathtub B is installed on the left side and a washing room C is installed on the right side. A mixed faucet S1 for supplying hot water to the bathtub B is attached to the front wall W1 slightly above the bathtub B, and a support table D installed slightly above the washing place C on the front wall W1. The side surface of the alligator is equipped with a mixing faucet S2 for the washing area C. In addition, at a position near the ceiling W2 of the front wall W1,
A pair of lighting devices 1 that illuminate the inside of the bathroom R are attached at right and left intervals.

In addition, M is an accessory table with a makeup mirror M1 attached above the support table D of the front wall W1, and H is a shower head which can be positioned on the upper side and the lower side of the front wall W1.

FIG. 1 is a side sectional view of the illuminating device, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. As shown in FIG. 1, the lighting device 1 includes a pedestal 10, a socket 11, a light source 12, a globe 13, a sealing packing 14, and a globe packing 1.
5, a mounting screw 16, and a reflector 17 which is a first and a second reflector.

As shown in FIG. 1, the pedestal 10 has a disk-shaped base 10A having a cylindrical support 10B on the outer periphery thereof, and the base 10A is closely attached to the front wall W1 of the bathroom R. In this state, the front wall W is
It is attached to 1. Further, in this pedestal 10, a screw portion 10a for attaching the globe 13 is formed on the inner surface side of the support portion 10B, and an opening 10b for attaching the socket 11 is formed in the central portion of the base portion 10A.

The socket 11 is, as shown in FIG.
A cylindrical body having a flange portion 11a at its front end, the rear side of which is inserted into the opening 10b of the pedestal 10 and is attached to this pedestal 10 with the front end flange portion 11a engaged around the opening 10b of the pedestal 10. ing. Therefore,
The rear side of the socket 11 passes through the opening W10 of the front wall W1 to form a gap S between the inner wall surface T of the building and the front wall W1 of the bathroom R.
It is positioned so that it projects inward and the front side slightly projects into the pedestal 10 by the thickness of the flange 11a. A power supply cord E is connected to the rear end of the socket 11.

The sealing packing 14 is fitted between the groove provided on the rear surface side of the pedestal 10 and the front wall W1 to prevent water vapor in the bathroom R from leaking to the inner wall surface T side of the building. are doing.

The light source 12 is composed of a mini krypton light bulb having a small diameter (for example, the diameter of the light emitting portion is about 33 mm). The light source 12 has a socket portion (not shown) having a socket 1
It is attached to this socket 11 in a state of being screwed into a front end side concave portion (not shown) of 1 and protruding from the base portion 10A of the pedestal 10 to the front side of the front wall W1. The light emitting portion 12a of the light source 12 is positioned in the globe 13 substantially at the center.

As shown in FIGS. 1 and 2, the globe 13 covers the periphery of the light source 12 and diffuses and irradiates the light from the light source 12 into the bathroom R. The globe 13 is made of a transparent material (for example, synthetic resin). Material) is formed by thin-wall molding. This globe 13 has a cylindrical main body portion 13A in which the front end face side of the cylindrical portion 13a is a spherical portion 13b having a large diameter.
And a small cylindrical connecting portion 13B formed on the rear end surface side of the main body portion 13A, and the screw portion 13c formed on the outer peripheral surface side of the connecting portion 13B is connected to the screw portion 10 of the pedestal 10.
It is attached to the pedestal 10 by being screwed into a. In this case, the end of the connecting portion 13B pressurizes the glove packing 15 attached to the inner surface side of the pedestal 10 to prevent water vapor or the like in the bathroom R from entering the glove 13.

Further, the globe 13 is provided with a corrugated lens portion 13d having a sawtooth-shaped surface on the inner surface side of the cylindrical portion 13a of the main body portion 13A. As shown in FIG. 3, the corrugated lens portion 13c causes the light L emitted from the light source 12 to the side of the cylindrical portion 13a of the main body portion 13A to pass through the front wall W.
It has a function of refracting to the front side away from 1.

Here, in the globe 13, the spherical surface portion 13b of the main body portion 13A is formed in a milky white shape in order to sufficiently diffuse the light, and the cylindrical portion 13a of the main body portion 13A increases the light transmittance. It is made transparent. However, the lower part 13a-1 (see FIG. 2) is included in the tubular part 13a so that the light with low diffusivity transmitted through the tubular part 13a does not directly enter the eyes of the bather and cause glare. The surface is subjected to embossing treatment (treatment for producing small irregularities on the surface), whereby the light transmitted through the cylindrical portion 13a is slightly diffused.

The reflecting plate 17 is arranged in the globe 13, reflects the light emitted from the light source 12, and efficiently radiates this light into the bathroom R which is a sanitary facility room. The reflector 17 includes a front reflector 17A that is a first reflector that reflects the light emitted to the rear of the light source 12 to the front of the light source 12, and the light emitted to the upper side of the light source 12. The lower reflector 17B is a second reflector that reflects downward of the light source 12.

As shown in FIGS. 1 and 2, the front reflector portion 17A is a disk-shaped member having a size substantially the same as the inner surface side of the connecting portion 13B of the globe 13, and has a stepped mounting hole. It is attached to the base portion 10A via a mounting screw 16 inserted from 17c. Further, the light source 12 side of the front reflector portion 17A is a mirror surface 17a formed in a substantially parabolic shape, and is positioned so that the light source 12 is placed at a substantially focal position.

As shown in FIGS. 1 and 2, the lower reflection plate portion 17B has a partial cylindrical shape formed on the upper edge side of the front reflection plate portion 17A so as to be orthogonal to the front reflection plate portion 17A. And is positioned in the globe 13 so as to cover the light source 12 from above. The light source 12 side of the lower reflection plate portion 17B has a mirror surface 17b which is obtained by moving a parabola (or a curve close to this) in parallel.
The light source 12 is positioned so that the light source 12 is located at a substantially focal position of this parabola.

Here, as shown in FIG. 2, the mounting hole 17c of the reflection plate 17 is a curved long hole, and this reflection plate 17 has a predetermined angle with respect to the pedestal 10 with the light source 12 as the center. Only can be rotated. Therefore, the reflector 1
By rotating 7, the position (orientation) of the lower reflector 17B can be freely changed within a range of a predetermined angle.

FIG. 4 shows the light distribution curve (cd /
(A) shows the light distribution curve on the side surface side of the lighting device 1, and (b) shows the light distribution curve on the front surface side of the lighting device 1. The chain line in the figure indicates the reflector plate 1.
The light distribution curve of the conventional illuminating device which does not have 7 etc. is shown.

As is apparent from FIG. 4 (a), in the conventional illuminating device, light is emitted toward the front side of the illuminating device with substantially equal luminosity in the front and in the vertical direction. In the device 1, the light traveling toward the rear side is reflected by the reflection plate 1
The luminous intensity on the front side is increased by the amount that is reflected by the front reflector plate 17A of No. 7 and is effectively used. Further, since the light directed to the upper side is reflected downward by the lower reflection plate portion 17B of the reflection plate 17, the lower side luminous intensity is increased and the upper side luminous intensity is decreased. This is also clearly shown in FIG. 4 (b). In addition, in FIG. 4B, the luminous intensity in the left-right direction of the illuminating device 1 is increased because the mirror surface 17a of the front reflector plate 17A is not accurately formed in a parabolic shape. It is considered that the plate portion 17A also generated light reflected in the left-right direction.

Next, the operation of the lighting device 1 will be described with reference to FIGS. 5 and 6. As shown in FIG. 5, the light L1 emitted from the light source 12 to the spherical surface portion 13b side of the globe 13 is diffused by the spherical surface portion 13b,
The light is emitted to the front side of the lighting device 1. Also, the light source 12
Light L2 emitted from the reflector 17 to the front reflector portion 17A side of the reflector plate 17 is reflected to the spherical portion 13b side of the globe 13 by the mirror surface 17a of the front reflector portion 17A, and then, like the light L1, this spherical portion. It is diffused by 13b and is irradiated to the front side of the lighting device 1. Therefore, the illuminance in the bathroom R is improved by the amount of the light L2 that is conventionally absorbed as heat on the base portion 10A side and radiated to the front side of the lighting device 1.

On the other hand, as shown in FIGS. 5 and 6,
The light L3 emitted from the light source 12 to the lower side of the tubular portion 13a of the globe 13 is diffused by the tubular portion 13a and is irradiated to the lower side of the lighting device 1. However, in this case, the light L3 is applied to the central portion side of the bathroom R by the corrugated lens portion 13d so as to move away from the front wall W1. Further, from the light source 12 to the lower reflection plate portion 1 of the reflection plate 17.
The light L4 emitted to the 7B side is generated by the lower reflection plate portion 17B.
After being reflected by the mirror surface 17b of the globe 13 toward the lower side of the tubular portion 13a of the globe 13, the light L3 is diffused by the tubular portion 13a.
Go in the same direction as. Therefore, much of the light L3 that is conventionally emitted to the upper side of the illumination device 1 is emitted to the lower side of the illumination device 1, so that the illuminance at the lower center of the bathroom R is improved.

Further, in particular, since the lower portion 13a-1 of the tubular portion 13a of the globe 13 is not subjected to the embossing treatment and is in a transparent state, a large amount of light is transmitted, and a portion directly below the lighting device 1 is provided. Illuminance is further improved. In this case, since the bather does not directly look at the lower portion 13a-1 side of the tubular portion 13a,
The bather does not feel glare due to the light transmitted through the lower portion 13a-1 side of the tubular portion 13a.

FIG. 7 shows the illuminance at a predetermined position in the bathroom.
It is shown by comparing the case where this lighting device is used and the case where the conventional lighting device installed at the same position as this lighting device is used. In this case, the lighting device 1 has the configuration shown in FIG.
It has a light distribution curve shown by a solid line, and the conventional lighting device has a light distribution curve shown by a chain line in FIG.

7A, for example, at a position 20 cm above the center of the right illuminating device 1 and 10 cm ahead of the front wall W1, as shown in FIG. 7B, Illuminance (1095 lux) in the case of the lighting device 1 is
It is kept lower than the illuminance (2660 lux) of the conventional lighting device. Since there is no bather in position a and it is not necessary to make it so bright, this lighting device 1
Then, a part of the light radiated toward the position (a) is focused on the lower side of the bathroom R where the bather is, via the lower reflection plate portion 17B.

Further, as shown in FIG. 7A, for example,
The front wall W is located 100 cm below the center of the left lighting device 1.
7B, the illuminance (193 lux) in the case of the illuminating device 1 is higher than the illuminance (119 lux) in the case of the conventional illuminating device at the position B above 1. In the vicinity of the position B, there are the accessory table M and the mixing faucet S2, and there is a bather near this, and it is necessary to make them bright. Therefore, in this lighting device 1, the front reflector plate 17A is used.
This is because the light is collected on the side of the position B via the lower reflection plate portion 17B or the like.

Further, as shown in FIG. 7A, for example, 55 from the floor of the washing area C below the lighting device 1 on the right side.
At a position C 30 cm above and 30 cm in front of the front wall W1, as shown in FIG. 7B, the illuminance (340 lux) in the case of the illumination device 1 is (257 lux in the case of the conventional illumination device). Lux). Even at this position c, since there is a bather to perform the bathing work, it is necessary to make it brighter. In this illuminating device 1, this position c side is provided via the front reflecting plate portion 17A and the lower reflecting plate portion 17B. This is because the light is collected in. The same applies to the positions D, E, and F shown in FIG.

As described above, in this illuminating device 1, the light to the rear side of the light source 12 which has not been used sufficiently in the globe 13 is reflected to the front side of the light source 12 in the globe 13.
Since the light source 12 is used, the illuminance in the bathroom R can be increased without increasing the light intensity of the light source 12. Therefore, the illuminance of the entire bathroom R is increased, and the bather can take a comfortable bath while feeling the spread of the bathroom space.

Further, in the illumination device 1, since the light that was conventionally emitted to the upper side of the light source is emitted to the lower side of the light source 12, the light that excessively illuminates the ceiling side of the bathroom R, It becomes possible to illuminate around the bathtub B and the washroom C below the bathroom R where brightness is required.
It enables effective lighting in the bathroom R. Therefore, as the illuminance around the mixed taps S1 and S2 and the accessory table M increases, bathing, shaving using the makeup mirror M1 and the like become easier. In this case, in this lighting device 1, the illuminance of the lower part of the space is relatively increased, and the illuminance difference between the upper part of the space and the lower part of the space is reduced, so that it is possible to maintain the uniformity of the space in terms of brightness. It is possible to produce a calm space.

In this lighting device 1, the amount of light to the ceiling W2 side decreases, but the distance between the ceiling W2 and the lighting device 1 is small, and there is also reflection from the wall surface of the bathroom R, so the ceiling of the bathroom R is small. The W2 side rarely becomes darker than the other parts. In this case, the illuminance on the ceiling W2 side can be further improved by finishing the wall surface of the bathroom R with a white color having good reflectance.

Further, in this illuminating device 1, the light emitted to the lower side of the light source 12 is directed not to the downward direction along the front wall W1 of the bathroom R but to the central side of the bathroom R. As a result, the illuminance on the side closer to the bather can be increased, and effective lighting in the bathroom R can be performed. In this case, since the lower portion 13a-1 of the tubular portion 13a of the globe 13 is transparent, it is possible to directly irradiate not the diffused light but the illuminance in the bathroom R directly below the lighting device 1. It is possible to further increase the illuminance of the part.

Further, in this illuminating device 1, since the reflecting plate 17 is rotatable around the light source and the position (orientation) of the lower reflecting plate portion 17B can be freely changed, not only directly below the illuminating device 1 but also For example, it is possible to collect light on the lower right side or the lower left side of the lighting device 1, and it is possible to easily increase the illuminance at a required location.

Further, in this illuminating device 1, since the light source 12 is a mini krypton light bulb having a diameter smaller than that of a general incandescent light bulb, it is easy to direct the light, and the above effect can be exerted more strongly. The degree of freedom in designing the gloves 13 can be increased. Furthermore, in this lighting device 1, since the socket 11 is projected toward the front wall W1 side and the projection of the socket 11 inside the globe 13 is suppressed as much as possible, the protrusion amount of the globe 13 from the front wall W1 is suppressed, As the feeling of pressure decreases,
It is possible to improve the atmosphere in the small bathroom R (to create a calm atmosphere). Of course, by reducing the amount of projection of the entire lighting device 1 from the front wall W1, the aesthetic appearance of the lighting device 1 can be improved.

The light source 12 is not limited to the mini krypton light bulb, but may be a general incandescent light bulb or a daylight lamp having a high color rendering property that makes the color of the wall material look beautiful.

Further, the reflector 17 is a front reflector 17A.
The lower reflection plate portion 17B may be separated. Further, the front reflector portion 17A and the lower reflector portion 17B are
The mirror surfaces 17a and 17b of the above have a flat surface as long as they can reflect light mainly forward or downward.
It may be a spherical surface or a cylindrical surface.
