  Moreover, in this illuminated vanity, it is preferable that a light guide pattern is formed on the upper surface of the emitting portion, and the lower surface of the emitting portion is the emitting surface.

  According to the illuminated vanity of the present invention, it is possible to improve the appearance by minimizing the protruding dimension from the front surface of the mirror cabinet while effectively illuminating the front surface of the mirror cabinet and its periphery.

It is a side view of 1st embodiment of this invention. It is sectional drawing which shows the part which attached the light source same as the above, and is a perspective view from the downward direction. It is a front view of an illuminating device same as the above. It is a sectional side view of a second embodiment. It is principal part sectional drawing same as the above. It is a top view for demonstrating the time of light emission same as the above. It is a figure explaining 3rd embodiment, (a) is a front view, (b) is a side view.

  The present invention will be described below with reference to the accompanying drawings.

  The first embodiment uses a lighted vanity 7a as an example of the lighted furniture of the present invention. Here, the bathroom vanity 7a as the furniture body 7 is a mirror cabinet 74 in which a mirror 73 is disposed on the front surface above the bathroom vanity body 71 provided with the bathroom bowl 72, as shown in FIGS. The lighting device A is attached to the upper part of the mirror cabinet 74.

  The illuminating device A includes a thin plate-shaped light guide member 2 and a light source 1 including a light emitting diode (hereinafter referred to as an LED 11) attached to face at least one end of the light guide member 2. . This illuminating device A is attached in a state where a pair of flat surfaces of the thin plate-like light guide member 2 are directed upward and downward.

  The light guide member 2 is configured by a thin plate-like transparent member having a substantially rectangular shape in plan view. The light guide member 2 has end faces so as to surround the outer periphery of the plate surface provided at the top and bottom. At least one of the peripheral ends of the light guide member 2 is an incident portion 4 on which light from the light source 1 is incident (in the present embodiment, an arbitrary one end portion is the incident portion 4). ), An end portion other than the incident portion 4 (in the present embodiment, one end portion of the end portions on the side substantially orthogonal to the side of the incident portion 4) is the emission portion 3. Of the pair of end portions paired with the emission portion 3, the other end portion opposite to the emission portion 3 (the other end portion when the emission portion 3 is one end portion; hereinafter, simply referred to as the other end portion). ) Is formed with a plurality of light guide patterns (not shown). A plurality of light guide patterns (not shown) are also formed on the upper surface of the emitting portion 3.

  As a result, the light incident from the incident portion 4 is irregularly reflected by the light guide pattern at the other end, and is also irregularly reflected by the light guide pattern on the upper surface of the emission portion 3, so that the light from the light source 1 is emitted from the emission portion 3. The light is emitted from the front surface and the lower surface. In the present embodiment, when the front surface of the emitting unit 3 is defined as the first emitting surface 31 and the lower surface of the emitting unit 3 is defined as the second emitting surface 32, the illumination device A of the present embodiment is the first emitting unit that becomes the emitting unit 3. The light can be emitted from a total of two locations, that is, the surface 31 and the second light emission surface 32, and the light emitted from the first light emission surface 31 becomes light emitted to the periphery of the face of the user of the vanity 7a. At the same time, the light emitted from the second emission surface 32 is light that illuminates the front surface of the vanity 7a.

  In addition, the front part in the vanity stand 7a of this embodiment said here refers to the mirror 73 which is the front part of the mirror cabinet 74, and the front surface of the furniture main body 7 made to illuminate by the projecting emission part 3 The part exposed to

  Moreover, the light source 1 is comprised by LED11 which is a point light source as already stated. The LEDs 11 are attached so as to face the end face of the incident portion 4 of the light guide member 2 and to be aligned in a straight line along the end face. Thus, by using a point light source such as the LED 11 for the light source 1, it is possible to further reduce the thickness of the light guide member 2. Furthermore, since the LED 11 can be used to emit light with low power consumption, the running cost can be reduced. In addition, although LED11 of this embodiment uses chip type chip LED11, it is not specifically limited. Further, the color of light of the LED 11 is not particularly limited.

  The light guide member 2 and the light source 1 configured as described above are housed in a housing 6 as shown in FIG.

  The housing 6 is divided into a light guide member housing 61 that houses the light guide member 2 and a light source housing 62 in which the light source 1 is housed, and the light source housing 62 is associated with the light guide member housing 61. It is attached detachably. A thin air layer k is formed between the light guide member housing 61 and the light guide member 2 as shown in FIG. 3, and light from the light source 1 is emitted from the incident portion 4 to the emission portion 3. The reflected light is prevented from being attenuated in the light guiding process toward the front. That is, as a result of contact of a member different from the light guide member 2 on the upper and lower reflection surfaces of the light guide member 2, the total reflection condition is prevented from being broken depending on the refractive index of the member.

  The illuminating device A configured as described above is attached to a bathroom vanity 7a as an example of the furniture body 7 as described above.

  The vanity table 7a of the present embodiment includes a vanity body 71 having a vanity bowl 72 and a mirror cabinet 74 provided on the upper surface of the vanity body 71. The mirror cabinet The lighting device A is attached to an upper portion of 74.

  The wash bowl 72 is a part that receives hot water discharged from a water tap 70 provided on the upper part of the wash bowl 72, and is formed in a bowl shape that opens upward. A drain port 721 that communicates with the drain pipe is provided at the lowest part of the wash bowl 72.

  In addition, a lower cabinet portion 79 is provided in a portion that constitutes the lower part of the vanity body 71 and is located below the wash bowl 72. The lower cabinet portion 79 includes a storage portion (not shown) that opens forward and can store small items therein, and an open / close door 78 that is pivotally supported on the front surface of the storage portion. .

  The mirror cabinet 74 provided at the upper position of the vanity main body 71 is mainly composed of a rectangular box-shaped cabinet body 76 opened forward, and a door body 77 is provided at the front of the cabinet body 76. Each of the doors 77 is pivotally supported so that it can be opened and closed, and a mirror 73 (end plate) is disposed on the front surface of the door body 77 substantially over the front surface. The interior of the cabinet body 76 is partitioned by a shelf plate (not shown) or a vertical partition plate (not shown) to form a storage portion (not shown).

  An accommodation recess 75 for accommodating the illumination device A is formed above the mirror cabinet 74 and above the mirror 73. The housing recess 75 includes the thin light guide member 2 and the light source 1 of the lighting device A (more precisely, the housing 6 in which the light guide member 2 and the light source 1 are housed), and a pair of the light guide members 2. It is formed in a size that can be embedded with the plane of That is, since the distance between the upper and lower opposing planes in the storage recess 75 can be shortened, the lighting device A for attaching the lighting device A compared to the conventional device using the lighting device A not using the light guide member 2 can be used. The installation space can be a small area.

  When the lighting device A is mounted in such a housing recess 75, all the portions of the lighting device A except for the emitting portion 3 are embedded in the housing recess 75. That is, most of the illumination device A is embedded in a portion where it cannot be seen, and only the emitting portion 3 is protruded from the mirror cabinet 74, and the protruding dimension from the mirror cabinet 74 is very small. It will be inconspicuous.

  In addition, since the light guide member 2 is formed in a thin plate shape, the light-emitting member 3 has an elongated linear appearance on the left and right in the front view. That is, since the protruding dimension can be reduced and the shape in front view can be made inconspicuous, the lighting device A can be made inconspicuous and the appearance of the vanity 7a can be improved. Can be made.

  In addition, since the light guide member 2 is plate-shaped in this way, the length between the side walls facing the upper and lower sides of the storage recess 75 provided in the upper part of the mirror cabinet 74 can be made as short as possible. That is, since the lighting device A can be attached even in a narrow space, there is an advantage that the degree of freedom in designing the vanity 7a can be increased.

  Thus, since the part exposed from the mirror cabinet 74 of the illuminating device A is not conspicuous, the vanity stand 7a of this embodiment differs greatly in design compared with the conventional one. In addition, since the light guide pattern is provided on the end face of the end opposite to the emission part 3, the light guide pattern is provided on the upper surface of the emission part 3, and the emission part 3 protrudes from the mirror cabinet 74. Only a slight protrusion illuminates the user with the light emitted from the first emission surface 31, and the light emitted from the second emission surface 32 with the light emitted from the second emission surface 32 is located in the lower part of the illuminating device A and the front surface portion ( That is, the mirror 73) can be illuminated and effective illumination can be performed.

  Next, another embodiment will be described with reference to FIG. Since the present embodiment is mostly the same as the embodiment shown in FIGS. 1 to 3, the same portions are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

  Similarly to the first embodiment, the second embodiment is an example in which the lighting device A is provided on the bathroom vanity 7a. However, the second embodiment and the first embodiment have a configuration of the lighting device A. Is different. That is, the illuminating device A of the present embodiment is configured by providing the light source 1 including the LED 11 at one end of the thin plate-shaped light guide member 2 and providing the emitting portion 3 at the other end opposite to the one end. ing.

  As shown in FIG. 4, in the light guide member 2 of the present embodiment, the upper surface of the light guide member 2 is slightly inclined with respect to the lower surface of the light guide member 2. The slope is such that the distance between the lower surface and the upper surface increases as it approaches the emitting portion 3 (i.e., the other end portion). That is, the thickness is gradually increased from the incident portion 4 to the emission portion 3.

  As shown in FIGS. 4 and 5, the emission unit 3 of the present embodiment is provided on the upper surface of the light guide member 2, and includes a first emission surface 31 configured by a curved surface that is smoothly continuous from the upper surface, and a light guide member 2 and the second emission surface 32 located on the lower surface on the other end side.

  In the present embodiment, the other end portion where the emitting portion 3 is formed is a first light guide surface 5 formed with a curved surface located downward as the tip end, and is repeatedly reflected in the light guide member 2. A part of the light is totally reflected toward the second emission surface 32 in the first light guide surface 5.

  Further, in the present embodiment, the first light guide surface 5 is the first light exit surface 31. That is, the light that does not satisfy the total reflection condition among the light incident on the first light guide surface 5 is emitted while being refracted without being totally reflected by the first light guide surface 5, while, as described above, Incident light that satisfies the total reflection condition on one light guide surface 5 is totally reflected on the first light guide surface 5, and most of the totally reflected light is emitted from the second light exit surface 32. That is, the illuminating device A of the present embodiment can emit light from a total of two locations, the first light exit surface 31 and the second light exit surface 32, and the light emitted from the first light exit surface 31 is emitted from the vanity 7a. The light is emitted to the periphery of the user's face, and the light emitted from the second emission surface 32 is light that illuminates the front surface of the vanity 7a (that is, the mirror 73 of the mirror cabinet 74).

  Also in this embodiment, the light guide member housing 61 and the light source housing 62 are provided, but the end portion of the light guide member housing 61 opposite to the end portion to which the light source housing 62 is attached. A lighting cover 63 having light transmittance is attached. The illumination cover 63 is detachably attached to the light guide member housing 61. The illumination cover 63 changes the traveling direction of the light transmitted through the illumination cover 63 and further condenses the transmitted light to increase the luminance. It has an enhancing effect. A first transmission portion 64 is provided on the front surface portion of the illumination cover 63, and the light emitted from the first emission surface 31 of the light guide member 2 is transmitted through the first transmission portion 64 and refracted. The light emission direction can be changed. That is, the light traveling direction can be set by the illumination cover 63.

  Furthermore, the lower surface of the illumination cover 63 is provided with a second transmission portion 65 that transmits and refracts the light emitted from the second emission surface 32 of the light guide member 2, so that the light on the second emission surface 32 travels. It is possible to set the direction.

  The lighting cover 63 is not necessarily attached, and may be temporarily not attached.

  Here, if the light guide member 2 is a rectangular parallelepiped light guide member 2 in which the distance between the incident part 4 and the light emission part 3 of the light guide member 2 is not sufficiently separated, light emitted from the LED 11 having a small size and directivity. May be emitted from the emission part 3 without spreading sufficiently, and in this case, light unevenness may occur in the light emitted by the non-irradiation region S generated between the adjacent LEDs 11. However, according to the illuminating device A of the present embodiment, the light guide member 2 has a plate shape even when the small and directional LED 11 is used as the light source 1. The distance between the portion 4 and the emitting portion 3 can be sufficiently taken, and as a result, the light emitted from the LED 11 can be emitted from the emitting portion 3 after sufficiently spreading in the light guide member 2 (see FIG. 6). That is, according to the illuminating device A of the present embodiment, it is possible to illuminate the irradiated object with light with little light unevenness. In addition, the non-irradiation area | region of the code | symbol S in FIG. 6 has shown the area | region which cannot be directly illuminated from the light source in the light emitted from the light source 1. FIG.

  Furthermore, since the light guide member 2 of the present embodiment is configured such that the plate thickness increases as the distance from the incident portion 4 to the emission portion 3 increases, the light from the incident light source 1 is repeatedly reflected in the light guide member 2. When going to the emission part 3, the incident angle (reference symbol i in FIG. 4) with respect to the reflecting surface can be increased as the reflection is repeated. As a result, the upper and lower reflecting surfaces in the light guide member 2 are incident on the upper and lower reflecting surfaces in the light guide member 2 under an incident condition that is less than the critical angle as much as possible. It is possible to prevent the total reflection condition of incident light from being broken. That is, it is possible to reduce the attenuation of light generated in the light guiding process.

  In addition, since the incident angle on the reflection surface of the light guide member 2 increases as the reflection is repeated in this manner, the mirror finish is insufficient on the upper and lower reflection surfaces of the light guide member 2. In addition, it is possible that the amount of light emitted from the emitting unit 3 is not greatly reduced.

  Moreover, when the traveling direction of the light in the light guide member 2 is considered as a unit vector, the component in the direction toward the emitting portion 3 (the direction of the arrow n in FIG. 4; the incident surface normal direction) repeats reflection. The component in the direction perpendicular to the direction toward the emitting portion 3 (the direction of the arrow m in FIG. 4) gradually decreases as the reflection is repeated. That is, the light travels in the light guide member 2 converges in a substantially constant direction (incident surface normal direction), so that optical operation is performed by the emitting unit 3 (for example, in this embodiment, an illumination cover). 63, the optical operation is performed, or the optical operation is performed by changing the curvature and the curved shape of the first emission surface 31).

  In addition, the illumination cover 63 attached to the illumination device A of the present embodiment can set the irradiation direction of the converged light emitted from the emission part 3 of the light guide member 2 as described above. . In other words, since the illumination cover 63 is detachably attached to the light guide member 2, the same type of light guide member 2 can be used for many types of vanities 7 a by simply providing a plurality of types of illumination covers 63. Inventory management becomes easy.

  The illumination cover 63 is configured to be subjected to light diffusion processing from the upper surface of the illumination cover 63 to the first transmission portion 64, and the second transmission portion 65 serving as the lower surface of the illumination cover 63 is configured as a transparent portion that is not subjected to light diffusion processing. May be. In this way, it is possible to avoid that the user feels dazzled by the light directly irradiating the user from the first transmission part 64, and the light emitted from the second transmission part 65 can prevent the mirror cabinet from being emitted. The front part (mirror 73) of 74 can be illuminated effectively. Of course, the second transmitting portion 65 in this case may be provided with a light condensing function or may be a simple transparent plate.

  Next, another embodiment will be described with reference to FIG. In addition, this embodiment uses the illuminating device A used in the first embodiment, and the same portions are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

  Such interior building material 8 is disposed so as to be installed between the studs, or is disposed on the front surface of the existing wall surface. For example, if a plurality of illuminated interior building materials 8 are installed side by side on a side surface of the room, the interior of the interior building materials 8 is illuminated by light emitted from the second emission surface 32 while illuminating the interior side with light emitted from the first emission surface 31. It is also possible to reveal an indoor space that gently illuminates the front part.

  On the other hand, if the lighting device A is turned upside down and installed in the interior building material 8 so as to irradiate the light emitted from the second emission surface 32 upward, the ceiling is illuminated by the light emitted from the second emission surface 32. Such illumination can also be performed.

  Further, unlike the above embodiment, a housing portion 84 for housing the lighting device A is provided along the upper surface of the lower horizontal core material 82a (that is, inside the lower part of the interior building material 8), and the second emission surface 32 is provided. If it is the interior building material 8 with illumination which exposed the output part 3 so that it may face downward and installed the illuminating device A, such an interior building material 8 will be arrange | positioned in a corridor or a toilet room, and the step lamp which illuminates a step Can also be used as By doing in this way, while being able to ensure safety at the feet in the dark, it is possible to greatly suppress the light that jumps directly into the eyes, for example, even when going to the toilet at midnight, It is also possible to prevent sleepiness from being awakened by the brightness of the illumination.

  In addition, although the 1st illumination device A is used for the illumination device A of this 3rd embodiment, it may replace with this illumination device A, and you may attach the illumination device A of 2nd embodiment.
