Description

  The present invention relates to a light emitting device and a vanity using the same.

  2. Description of the Related Art Conventionally, as a bathroom vanity to which a light emitting device is attached, for example, the one shown in Patent Document 1 is known. The bathroom vanity shown by this patent document 1 is one in which a light emitting device serving as illumination is attached to the front of the upper part of the upper cabinet. This light-emitting device is mounted so that most of the light-emitting devices such as the illumination cover and the illuminating lamp that become the light-emitting portion protrude forward from the front surface of the upper cabinet. It is structured so that the user can easily use the vanity by illuminating a mirror in a certain wash bowl or upper cabinet.

JP 2008-279171 A

  By the way, the vanity table like this patent document 1 is attached so that the light-emitting device may protrude largely in front of the upper part of an upper cabinet as mentioned above, and the wash bowl and mirror in the lower part of a protrusion part are attached. Although the advantage of improved usability can be obtained, the protruding part is large, so that the protruding part is conspicuous not only when the light emitting device is irradiated but also when it is not irradiated. There was room for improvement.

  Therefore, as shown in FIG. 9, the present inventors arrange the light source 1 so as to face the end surface of the rear side of the plate-shaped light guide member 20 (that is, the back side of the upper cabinet). In addition, a light emitting device A ′ in which the front end of the light guide member 20 is a light output part 3 having an inclined surface has been developed.

  According to the light emitting device A ′ configured as described above, since the light exiting portion 3 is only a small part of the front end of the light guide member 20, most of the light emitting device A ′ excluding the light exiting portion 3 is placed on the upper part of the bathroom vanity. While embedding in the invisible part inside a cabinet, only the light emission part 3 was exposed from the upper cabinet, and the appearance of the vanity could be improved significantly.

  Moreover, the front end of the light guide member 20 is configured by the light output unit 3 having the inclined surface (light guide surface 31). The light output from the light output unit 3 is different between the first light output unit 32 and the second light output unit 33. This is to enable irradiation in two directions. That is, by configuring the front end of the light guide member 20 with an inclined surface (light guide surface 31), out of the light propagated by multiple reflection in the light guide member 20, the inclined surface (light guide surface 31) is transmitted. Those that have been totally reflected are emitted from the second light exit portion 33, and those that do not satisfy the total reflection condition with respect to the inclined surface (light guide surface 31) are emitted from the first light exit portion 32. Thus, by making it possible to irradiate in two different directions, the second light emission is emitted from the first light output portion 32 of the light guide member 20 toward the front and effectively illuminating the user's face. The light is emitted from the light exit portion 33 obliquely downward in the front direction so as to illuminate the wash bowl side of the wash vanity that is the user's hand.

  However, according to such a configuration, as shown in FIG. 9, although light irradiation can be performed in two different directions, the light emitted from the second light emitting unit 33 is light in a direction close to the vertically downward direction. However, since the light is only directed to the front obliquely downward, it does not illuminate the wash bowl and cannot effectively irradiate the wash bowl.

  Here, in order to perform more effective illumination, in order to perform an optical operation so that the irradiation direction of the irradiation light directed downward and obliquely downward from the second light output unit 33 is closer to the vertically downward side, the inclined surface is used. It is conceivable to make the inclination angle of the (light guide surface 31) closer to a right angle.

  However, as shown in FIG. 10, when this inclined surface (light guide surface 31 ') is brought closer to a right angle, the light emitted from the second light exit portion 33' is slightly vertically downward (that is, toward the wash bowl side). ) Although approaching, it is still light that irradiates in the front oblique direction. Moreover, when the angle of the light guide surface 31 ′ is close to a right angle, the light propagating in the light guide member 20 is incident on the light guide surface 31 ′. Since the angle becomes small, there is a problem that the amount of light that is totally reflected on the inclined surface (light guide surface 31 ′) and emitted from the second light exit portion 33 ′ is greatly reduced.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to irradiate the irradiation light while maintaining the amount of light in the front oblique direction reflected and emitted from the light guide surface of the light emitting device. An object of the present invention is to provide a light emitting device capable of performing optical operation of a direction and a vanity using the same.

  In order to solve the above problems, a light emitting device of the present invention and a vanity equipped with the light emitting device have the following configuration.

And an illumination cover 5 that covers the light output part 3. A light guide surface 31 formed of a curved surface or an inclined surface that is closer to the second main surface 21b from the first main surface 21a is provided at the end of the light guide member 20 on the light output portion 4 side. When the light incident portion 4 is defined as the rear and the light exit portion 3 is defined as the front, the light in the front oblique direction reflected from the light guide surface 31 and emitted from the front end portion of the second main surface 21b is further rearward. The lens part 55 which refracts so that it may bend is provided.

  With this configuration, the light in the front oblique direction reflected from the light guide surface 31 and emitted from the front end portion of the second main surface 21b is refracted so as to bend further to the rear side without reducing the amount of light. be able to.

  The vanity 7 of the present invention according to claim 2 is a vanity in which a mirror surface portion 74 is erected on the back of the vanity 72 on the vanity 71 having the vanity bowl 72. The light emitting device A according to claim 1 is provided above the mirror surface portion 74. In the light emitting device A, the light emitting portion 3 and the lens portion 55 protrude forward from the mirror surface portion 74. The light refracted by the lens portion 55 of the illumination cover 5 irradiates either the wash bowl 72 or the mirror surface portion 74 or both the wash bowl 72 and the mirror surface portion 74.

  A light emitting device A according to an embodiment of the present invention is shown in FIG. 1, and FIG. 6 shows an example of use in a vanity 7 to which the light emitting device A is attached. The bathroom vanity 7 according to this embodiment is configured such that a mirror surface portion 74 is erected and arranged at the rear of a bathroom surface 71 having a bathroom bowl 72, and the light emitting device A is attached to the upper portion of the mirror surface portion 74.

  As shown in FIGS. 1 and 3, the light emitting device A includes a thin plate-shaped light guide 2 and a light emitting diode (hereinafter referred to as an LED) provided to face an end surface of one end of the light guide 2. A light source 1 comprising 11 and an illumination cover 5 covering the light output part 3 of the light guide part 2. In the present embodiment, the light emitting device A includes a pair of main surfaces 21 (first main surface 21a and second main surface 21b) of the thin plate-shaped light guide unit 2 with the first main surface 21a facing upward, The two main surfaces 21b are attached in a downward state.

  As shown in FIG. 4, the light guide 2 is configured by connecting a plurality of thin light-transmitting transparent light guide members 20 in the longitudinal direction (six in this embodiment are connected). ing. In the light guide section 2, the side where the light incident section 4 and the light exit section 3 are located is a long side 22 in a plan view, and the side substantially perpendicular to the light incident section 4 and the light exit section 3 is a short side 23. ing. The long side 22 is sufficiently longer than the short side 23, and is a thin plate-like light guide section 2 having a planar view as a whole and a thin thickness.

  As shown in FIG. 3, the light guide member 20 is configured by surrounding the outer circumferences of the first main surface 21 a and the second main surface 21 b with end surfaces. The light guide member 20 has a light incident portion 4 at an end surface (one end portion) at a rear end portion, and a front end portion which is an end portion opposite to the light incident portion 4 of the light guide member 20 is a light exit portion. It is part 3.

  In the light guide member 20 of the present embodiment, the first main surface 21 a of the light guide member 20 is slightly inclined with respect to the second main surface 21 b of the light guide member 20, and this inclination is emitted from the light incident part 4. The slope is such that the distance between the lower surface and the upper surface increases as the portion 3 is approached. That is, the plate thickness is gradually increased from the light incident portion 4 to the light exit portion 3.

  As shown in FIGS. 2 and 3 and the like, the light output part 3 of the present embodiment is provided on the first main surface 21a of the light guide member 20, and is configured by a curved surface that is smoothly continuous from the first main surface.

It is formed with a curved surface. The light that enters the curved surface and exits while being refracted and transmitted without being totally reflected is the light that exits from the first light exit portion 32. In other words, a part of the light propagated while performing multiple reflection in the light guide member 20 becomes light emitted from the first light output part 32. On the other hand, the curved surface (that is, the first light exit portion 32) located at the lower end of the front end is also the light guide surface 31. The light guide surface 31 can guide the light totally reflected on the light guide surface 31 toward the second light output portion 33.

A convex curved surface 35 located above is formed. A rear portion of the protruding portion 34 is a step portion 36, and the step portion 36 comes into contact with a lower contact portion 63 of the housing 6 described later so that the light guide member 20 can be positioned with respect to the housing 6. It has a configuration. The boundary between the second light output part 33 and the first light output part 32 is located at substantially the same height as the lower surface of the light guide member 20 or below the lower surface of the light guide member 20. .

  When light from the light source 1 is incident on such a light guide member 20, the light propagates while performing multiple reflection in the light guide member 20, and the light guide surface 31 out of the light reaching the light output unit 3. The light that does not satisfy the total reflection condition becomes light emitted from the first light output part 32, and the light that satisfies the total reflection condition with respect to the light guide surface 31 is totally reflected toward the second light output part 33, Most of the light is emitted from the second light output portion 33. That is, the light-emitting device A of the present embodiment can emit light from two different places of the first light output part 32 and the second light output part 33, and the light emitted from the first light output part 32 is directed substantially forward in the horizontal direction. In addition, the light emitted from the second light output portion 33 is light directed obliquely downward to the front.

  In addition, since the second light exit portion 33 is configured by the convex curved surface 35, the second light exit portion 33 is further vertically lower than the case where the second light exit portion 33 is not provided with the convex curved surface 35 before entering the lens portion 55 of the illumination cover 5. The light can be emitted in a direction close to the side.

  The light source 1 is configured by providing a plurality of LEDs 11 that are directional point light sources. More specifically, the light source 1 is configured by arranging the LEDs 11 on the substrate in a straight line in the width direction of the light guide member 20 (direction parallel to the long side 22) with the LEDs 11 spaced apart at a constant interval. In addition, irradiation is performed from the rear to the front (from the rear toward the light output unit 3) so that the optical axis is in a direction substantially parallel to the direction connecting the light input unit 4 and the light output unit 3. Yes. Such a light source 1 is disposed along the long side 22 where the light incident portion 4 of the light guide portion 2 is configured by connecting a plurality of light guide members 20 in the longitudinal direction. By configuring the light source 1 with the LEDs 11 in this manner, the light guide member 20 can be further thinned. More specifically, since the LED 11 is used as the light source 1, light can be emitted with low power consumption, so that 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.

At this time, the light guide member 20 is positioned by the upper contact portion 681 of the upper housing 68, the mounting portion 62 and the lower contact portion 63 of the lower housing 61, and is sandwiched and fixed by the elastic force of the illumination cover 5. Therefore, the light guide member 20 is prevented from falling off or rattling.

  The light emitting device A configured as described above is mounted on the vanity 7 as described above.

  As shown in FIG. 6, the vanity table 7 of the present embodiment includes a vanity bed 71 provided with a vanity bowl 72, a mirror surface portion 74 erected on the rear side of the vanity bowl 72 on the vanity table 71, and a mirror surface The light emitting device A is attached to the upper part of the mirror surface portion 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 portion communicating with the drain pipe is provided at the lowest portion of the wash bowl 72.

  The lower part of the washstand 71 is a storage part 79 (specifically, below the washbowl 72). The storage portion 79 includes a drawer portion 78 that can store small items therein and is slidable.

  A mirror surface 74 is erected from the rear end of the washstand 71. The mirror surface portion 74 includes a backboard portion 74a, a cabinet body 76, a door body 77, and a mirror 73. A door body is provided at the front of the rectangular box-shaped cabinet body 76 provided on the upper portion of the backboard portion 74a. 77 is pivotally supported to be freely opened and closed. A mirror 73 is disposed on the front surface of the door body 77. In addition, a device housing portion 75 in which the light emitting device A is housed is provided at the upper portion of the cabinet body 76, and the upper end of the door body 77 on which the mirror 73 is arranged is more than the bottom portion of the device housing portion 75.

  When light is emitted from the light emitting device A of the vanity 7 having such a configuration, the light around the face of the user of the vanity 7 can be irradiated by the light emitted from the first light emitting unit 32. Further, the light that is emitted obliquely downward from the second light exiting portion 33 and then refracted vertically downward by the lens portion 55 of the illumination cover 5 effectively causes the wash bowl 72 of the vanity 7 to be handed to the user. The use of the vanity 7 is greatly improved. In addition, although the light from the 2nd light emission part 33 refracted to the back side by the lens part 55 includes the light which illuminates the direction which faced the mirror 73 side rather than the perpendicular downward direction, the site | part in which the light-emitting device A was installed If the mirror 73 side is illuminated, the light reflected by the mirror 73 can indirectly illuminate the wash bowl 72, and in any case, it can contribute as light that illuminates the wash bowl 72. .

  In addition, since the light diffusing portion 56 is provided in the front portion 53 of the illumination cover 5, the light from the first light emitting portion 32 that illuminates the periphery of the user's face is diffused to become soft light, and the user feels dazzling. Can be prevented.

  Further, the luminance of the illumination light may be increased by configuring the lens portion 55 of the illumination cover 5 with a condensable curvature so that the light from the second light output portion 33 is condensed while being refracted.

  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 7, the same portions are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

  The lens portion 55 of the illumination cover 5 of the present embodiment is composed of a convex lens that protrudes upward from the lower surface portion 54 of the illumination cover 5, and the lower surface of the lower surface portion 54 is formed as a flat surface. The lens center portion 57 (that is, the thickest portion of the lens portion 55), which is an intermediate portion in the front-rear direction of the lens portion 55, is located behind the light emission portion of the second light emitting portion 33. Specifically, the light guide member 20 is positioned so as to substantially overlap the stepped portion 36 behind the protruding portion 34 of the second light output portion 33.

  Even with such a configuration, as with the illumination cover 5 of the first embodiment, the user's hand of the vanity table 7 can be effectively illuminated. In addition, since the lower surface of the illumination cover 5 is a flat surface, the protruding portion can be made even less conspicuous.

  In said 1st and 2nd embodiment, although the light guide member 20 of the light-emitting device A is comprised by the thin plate-shaped transparent member, for example, an acrylic resin, glass, polycarbonate resin, an epoxy resin, a silicone resin, etc. Can be preferably used. Moreover, the material of the illumination cover 5 is not limited to acrylic resin, and the above-mentioned materials can be preferably used.

  In the first and second embodiments, the lens unit 55 is a convex lens having a smooth curved surface. However, the lens unit 55 does not have to be a curved surface. For example, the curvature of the curved surface is approximated by a straight line. May be. Furthermore, although the 1st light emission part 32 (light guide surface 31) was formed in the curved surface, and the 2nd light emission part 33 was demonstrated in the example formed in the convex curved surface 35, this 1st light emission part 32 (light guide surface 31) was demonstrated. In addition, the second light output portion 33 can obtain the same effect even when approximated by a linear inclined surface.

  Furthermore, in the said embodiment, although the 2nd light emission part 33 demonstrated with the structure which provided the convex curve 35 in the protrusion part 34, the structure which provided the convex curve 35 in this protrusion part 34 is not essential, It may be a flat surface in which the protruding portion 34 is not provided (that is, a configuration in which the lower surface of the light guide member 20 is a uniform flat surface).
