The lighting unit 02a uses the 60 W incandescent lamp 11 and is mounted in the lamp socket 17, and the lighting unit 03a has four units.
The 0W reflector bulb 12 is used to mount the lamp socket 18 on the lamp socket 17, the lamp socket 17 is fixed to the main body 40 vertically, and the lamp socket 18 is inclined outward and fixed to the main body 40, and the main body 40 is mounted on the ceiling 100 of the toilet. ing. The cover 05 is milky white and has a shape that covers the lamp 11 and the lamp 12, and is fixed to the main body 40. In the illumination unit 02a, the light emitted from the 60W incandescent light bulb 11 is diffused by the milky white cover 05 and irradiates the inside of the toilet as soft light as a whole. In addition, the illumination unit 03a is provided with the 40 W reflector bulb 12 as a light source, and the reflecting surface provided on the inner surface of the bulb of this bulb can irradiate light with a relatively narrow light distribution angle such as 20 °. . In other words, the lighting unit 02a is general lighting, and the lighting unit 03a is local lighting.

In the conventional toilet, only the general lighting is used and the space is not changed at all. However, by using the lighting of this embodiment for the toilet, the general lighting ensures sufficient brightness in the toilet. , Local lighting can be used to illuminate specific objects or places. In addition, as the toilet, a unit toilet in which various units can be selected according to the taste of the user can be preferably used. In the unit toilet, it is possible to check the light distribution state of the lighting device in a showroom or the like in advance, so that the toilet space that is more suitable for the user can be set. In addition, it is possible to prevent construction mistakes at the site by previously mounting the lighting fixture at a position where the interior of the unit toilet can be appropriately illuminated, or by performing the positioning marking on the member of the mounting surface.

Further, in the illumination unit 03a which is a local illumination, since the lamp socket 18 is inclined outward,
Inevitably, the 40 W reflector bulb 12 mounted in the lamp socket 18 and its irradiation light also incline toward the outside. Therefore, since it is possible to illuminate obliquely from the lighting fixture installed in the center of the toilet ceiling, the light distribution angle is relatively narrow, that is, the light is condensed toward the paintings on the wall or the vase on the shelf. It can be irradiated with light. In addition, by adjusting the state of inclination and the state of the cover, when reading, to the hand when sitting on the toilet seat, to improve the visibility of each part, for example, the operation part of various equipment, the toilet bowl It is sufficient to irradiate the face of the subject to the paper wrapper or to improve the reflection of the mirror. Also, if the corner of the toilet is shaded by a shelf or the like and it is dark, it is sufficient to irradiate it toward that corner, not only that part becomes bright, but also
Another effect is that the toilet looks wide.

In this embodiment, the local illumination is radiated obliquely, but it may be radiated directly below. In that case, it is necessary to consider the mounting position of the lighting unit. For example, in order to make the hand bright when reading, the lighting unit 03a, that is, the local lighting may be mounted above the front end of the toilet body. .

Further, the number of local illuminations is not limited to one, and a plurality of local illuminations may be provided, and the type thereof may be appropriately selected depending on the light distribution.

Further, the illuminating section 02a may be made an indirect illumination (not shown) so that the direct light of the light source does not enter the field of view, and if the glare is suppressed, a comfortable atmosphere is provided. In this case, there is also a method of using an opaque material for the cover of the illumination unit 03a so that the direct light of the light source does not enter the field of view.

3 to 6 are front views of a lighting apparatus according to another embodiment of the present invention.

In FIG. 3, the local illumination 03b has a reflector 31 above the 40 W mini-krypton light bulb 13, and the reflector 31
The cross-sectional shape of is a high-magnification elliptic curve. When such a reflector is attached, not only the direct light from the lamp but also the reflected light from the reflector is added, and the light becomes a condensed light with a relatively narrow light distribution angle, making it possible to brighten a specific object or place. You can In this embodiment, the cross-sectional shape of the reflection plate is an elliptic curve, but it may be a parabolic curve.

FIG. 4 shows still another embodiment in which the local illumination 03c has a condenser lens 32 below the 40 W mini-krypton bulb 13 and has a rounded convex downward cross section. When such a lens is attached, it becomes condensed light with a relatively narrow light distribution angle, and it is possible to make a specific object or place bright. In the present embodiment, the cross-sectional shape of the lens is an R shape that is convex downward, but it is an R shape that is convex only on the upper side, or an R shape that is convex on both sides, or an R shape that is concave on the upper side and convex on the lower side. Is also good.

Further, the lens is, as shown in FIG.
A plurality of refracting lenses 33 may be used for focusing. Furthermore, it goes without saying that if both the reflector and the lens are used, the utilization efficiency of light is further increased, and a specific object or place can be illuminated more efficiently.

Further, as shown in FIG.
By mounting the 3e lamp socket 18 on the mounting bracket 21 whose tilt angle θ can be adjusted to a predetermined angle, the optimum irradiation direction 91 can be selected according to the user's preference.

In the embodiment described above, the material of the reflector is not only aluminum mirror surface material but also metal or resin molded product which is coated or vapor-deposited with high reflectance, aluminum film is adhered, and white. It may be a resin film attached or a white resin molded product with a mirror finish.

It can be slid up and down, and the vertical position of the cover 08b connected to the arm 62a can be adjusted. Further, the movable portion 60 can rotate counterclockwise about this point in the range of 0 ° to 90 °. Further, the arm fixing screw 52 can be fixed / positioned by tightening this after adjusting the slide length of the arm described above. That is, the arm 61a, the arm 61b, the movable portion 60, the arm 62a, and the arm 62b can adjust the position of the local illumination 03f with respect to the main body rotating portion 42b in the horizontal direction, the vertical direction, and the counterclockwise direction. The fixing screw 52 has a structure in which positioning can be performed.

Further, as described above, the main body rotating portion 42
Since b can rotate 360 ° in the horizontal direction about the 60W incandescent light bulb 11 which is the light source of the general illumination 02f, as a result, the local illumination 03f can rotate 360 ° in the horizontal direction with respect to the general illumination 02f. The position can be adjusted in the horizontal and vertical directions, and the position can be adjusted by rotating it counterclockwise from 0 ° to 90 °, and the positioning can be performed.

Therefore, it is possible to irradiate the wall surface / floor surface of the toilet according to the user's preference while adjusting the local illumination 03f freely. Further, after the adjustment, the position can be securely fixed so that the irradiation position does not shift.

9 and 10 are a front view and a bottom view of a lighting apparatus according to another embodiment of the present invention.

In the lighting fixture 01g, the local lighting 03g is arranged at the center of the general lighting 02g.

The general illumination 02g uses two 40W mini-krypton bulbs 14, each mounted in a lamp socket 19 and fixed to the main body 43. These light bulbs are covered with a milky white cover 09a, and the light emitted from the light bulbs is diffused by the cover 09a and radiated into the toilet. The cover 09a is connected to the main body 43 with a screw (not shown).

The local illumination 03g uses a 40W mini-krypton bulb 13 and is attached to a lamp socket 18 and fixed to a non-transparent cover 09b. A reflector 34 having a parabolic cross section is attached above the 40 W mini-krypton light bulb 13 so that the light condensed by the reflection is emitted. The cover 09b is an arm 6
5, the movable portion 64 and the arm 66 are held by the arm holding portion 67 fixed to the main body 43, and the irradiation direction of the local illumination 02g can be rotated by 360 ° about the arm 66. In the range of the opening 93 of the cover 09a,
It is rotatable in the direction of arrow 92.

As a result, the local illumination 03g can be freely radiated to the portion such as the wall surface / floor surface of the toilet according to the user's preference.

Although the local illumination 03g is projected from the cover 09a in this embodiment, it may not be projected. Further, the length of the arm 65 of the local illumination 03g can be adjusted, and the arm 65 can be moved in the vertical direction and can be positioned by a fixing screw, so that the irradiation range can be further expanded.

A 40 W mini-krypton bulb was used as the lamp for the general illumination 02 g and the local illumination 03 g.
Not limited to this, a discharge lamp such as a ring fluorescent lamp may be used for general lighting, and a halogen lamp or a small metal halide lamp may be used for local lighting.

Needless to say, the efficiency of light utilization is improved by attaching a reflecting member to the inner surface of the main body 43 of the general illumination 02g or adding a lens having a light condensing effect to the local illumination 03g.

In the above embodiments, the light transmittance of the cover of the portion facing the entrance / exit direction of the toilet is, for example, insert-molded with a member having a lower transmittance than the other cover portion, or lower than the other portion. If the device is made to have a low transmittance by attaching a resin film having a high rate or making the plate thickness thicker than other portions, it is possible to reduce glare and discomfort felt by the user when entering the toilet.
Here, the low transmittance portion is a part, and the other portion transmits light with an appropriate transmittance, so that sufficient brightness in the toilet can be secured.

If the local lighting is rotatable, it is difficult to predict where the cover will be in the toilet entrance direction. Therefore, the local lighting cover is preferably made of an opaque material.

In the above embodiments, the mounting position of the lighting equipment is not limited to the ceiling surface in the toilet, but may be the wall surface.

Turn on or fade in 75b. Further, when the lighting switch is turned off when the user exits the toilet, the light is turned off or faded out based on the preset stored information as in the case of lighting. Also, the compulsory lighting switch 77a
When is turned on, the light source 75a can be forcibly turned on at the rated brightness regardless of the above-described operation, and the light source 75b can also be forcibly turned on in the case of the forced lighting switch 77b.

For example, a normal time zone (6:00 to 23:00)
Both the lighting unit 81a and the lighting unit 82b are lit at the rated brightness and there is no fade-in or fade-out. During the midnight time period (23:00 to 6:00), the lighting unit 81a does not turn on and the lighting unit 82b does not turn on. If you set it to 20% of the rated brightness, fade-in, and no fade-out, it will light up brightly at the rated brightness instantly during normal time, so you can comfortably use it at night or at night. When going to the toilet in the half awake state at midnight, only the lighting part 82b gradually becomes slightly bright to 20% of the rated brightness, so that the glare and discomfort felt by the user can be drastically reduced, and the user can sleep again. It is possible to avoid the problem of difficulty getting a job. In addition, if the lighting switch 72 is inside the toilet due to the building, and the area around the toilet is dark at midnight, if you set the lights to fade out during the night, it will gradually darken, and the dark adaptation will be delayed when you leave the toilet. It is possible to avoid the problem that the surroundings are hard to see. Further, the brightness is not so high as to be necessary for the stool and to be a stimulus for awakening, so that it does not prevent the user from getting another sleep. Also, since there is a faint light until you leave the toilet, you do not feel inconvenience. The forced lighting switch can be effectively used because it can be surely brightened during cleaning or in an emergency.

As another example, the illuminating section 81a is a general illumination and the illuminating section 81b is a local illumination, and at night, only the local illumination is turned on or faded in while facing the wall or the ornament on the shelf. You can also use it to create a fantastic toilet space, or to illuminate the local lighting toward your hand when you sit down to use it as a reading light.

The clock circuit / storage circuit 73 may display the time itself. Further, the clock circuit unit / storage circuit unit 73 and the dimming circuit units 74a and 74b may be built in the lighting equipment or may be separately arranged. As a separate place, it may be installed on the wall inside the toilet, built in the lighting switch outside the toilet, or installed behind the ceiling.

FIG. 12 is a block diagram of an electric control circuit section according to another embodiment of the illumination of the present invention.

The AC power supply 71 passes through the human body detection / determination circuit section / brightness determination circuit section / storage circuit section 82 and then the illumination section 81.
c, and is connected to the illumination unit 81d. Lighting unit 81c
Includes a dimming circuit section 74c and a light source 75c. The dimming circuit section 74c includes a human body detection determination circuit section, a brightness determination circuit section,
The signal 76c from the memory circuit unit 82 and the light source 75c are connected. Similarly, the illumination unit 81d is also composed of a dimming circuit unit 74d and a light source 75d. The dimming circuit unit 74d connects the signal 76d from the human body detection judgment circuit unit / brightness judgment circuit unit / memory circuit unit 82 and the light source 75d. Has been done. Light control circuit 7
4c and 74d receive signals 76c and 76d and receive a light source 75
For c and 75d, lighting with a rated brightness, lighting with a predetermined dimming amount, or fade-in or fade-out can be performed. A brightness sensor 78 and a human body detection sensor 79 are connected to the human body detection determination circuit unit / brightness determination circuit unit / storage circuit unit 82. Further, in the human body detection determination circuit unit / brightness determination circuit unit / storage circuit unit 82,
The dimming amount of the light sources 75c and 75d, necessity of fade-in / fade-out, threshold for human body detection determination, and threshold for brightness determination are stored and can be changed. The change is made by operating various setting knobs (not shown). Two thresholds for determining the brightness around the brightness sensor 78 are set, and when the brightness around the brightness sensor 78 is less than or equal to the smallest threshold, mode A, between the two thresholds is set. The brightness is set to mode B, and when it is greater than or equal to the maximum threshold, the brightness is set to mode C. Further, the illumination units 81c and 81d can be controlled independently.

Next, the operation will be described.

When the user approaches the human body detection sensor 79,
If the human body detection determination circuit unit compares it with a preset threshold value to determine whether it is a human body and determines that it is a human body, the brightness sensor 7
At 9, the brightness of the surrounding area is detected and compared with a preset threshold value to determine the mode. Then, information about the preset dimming amount or necessity of fade-in / fade-out for each mode is called from the storage circuit unit, and the information is sent by the signals 76c and 76d to the dimming circuit units 74c and 74.
Then, the dimmer circuit sections 74c and 74d turn on or fade in the light sources 75c and 75d based on the information. In addition, when a person moves away from the toilet after using the toilet, the human body detection determination circuit section compares it with a preset threshold value to determine whether it is a human body, and if it is determined that it is not a human body, it turns off or fades out depending on the mode. To do.

For example, if the threshold values for the brightness sensor determination are set to daytime when the brightness sensor 79 is bright, slightly dark night, and fairly dark midnight, the three types of modes are daytime, nighttime, It will be set at midnight. Then, depending on the time of day, the desired lighting state or dimming amount,
Alternatively, by presetting the necessity of fade-in and fade-out, it is possible to automatically obtain a favorite light. That is, the same light control as the brightness control according to the time zone described in FIG. 11 is possible. Also,
There is also an advantage that the brightness can be controlled by the brightness around the brightness sensor 79 without worrying that the time zones of daytime, nighttime, and midnight vary depending on the season. Furthermore, since it can be turned on and off automatically by the human body detection sensor, it is possible to prevent forgetting to turn it off, which is very convenient and at the same time power saving.

Although the number of modes is three in the embodiment, the number of modes is not limited to three and may be two or four or more. In addition, the human body detection sensor 78, the brightness sensor 79, the human body detection determination circuit unit / brightness determination circuit unit / storage circuit unit 82, and the dimming circuit units 74c and 74d may be incorporated in the lighting fixture or separately. You can As a separate place, it may be attached to the wall inside the toilet, the wall on the entrance side outside the toilet, or the ceiling surface.

The method of controlling the illumination may be other than this embodiment, for example, a method in which the lighting switch is continuously pressed twice and the mode is switched if the ON intervals of the two switches are within a predetermined time. good.

Further, a mode changeover switch is provided, the mode is switched to a new mode for a predetermined time after the switch is turned on, and after the predetermined time has elapsed, the mode is returned to the initial mode. Furthermore, at the same time every day from the next day, it automatically switches to that mode, and if there is no operation of the mode switch,
Repeat the same operation. That is, the mode time zone may be stored once the mode is set, and the setting may be reproduced in a 24-hour cycle.

In the brightness sensor determination circuit section, the mode determination is performed with respect to the threshold value. However, the present invention is not limited to this, and the brightness sensor may be installed outside the toilet, or may be installed inside and outside the toilet, respectively. By controlling the brightness so that it is almost the same as the brightness outside the toilet and reducing the difference in illuminance inside and outside, it reduces the discomfort felt by the user due to the time required for light adaptation and dark adaptation, and further It is possible to prevent things from tripping over and getting injured.

From the above, the light control of a plurality of light sources becomes possible according to the preference of the user, and a comfortable toilet illumination can be realized. Furthermore, it is possible to control each light of the general lighting and the local lighting, and to obtain a toilet lighting which has never existed before and to meet various needs. It is needless to say that if the size of the toilet or the unit toilet or the reflectance of the wall is known in advance, more suitable lighting fixtures and lighting states can be controlled accordingly.
