[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror device for projecting a human body, and more particularly to a mirror device for projecting light from the surface of the mirror device toward the human body and projecting the human body on the surface of the mirror device, and a basin provided with the same.

[Prior art]

2. Description of the Related Art Conventionally, mirror devices such as portable, stationary, and vanity tables use sunlight, outdoor lighting, indoor lighting, and light sources such as light bulbs and fluorescent lamps exclusively arranged around the mirror device. By irradiating light to a human body positioned in front of the mirror device and making the reflected light incident on the surface of the mirror device, the human body positioned in front of the mirror device is brightly projected. The mirror device used here is formed by depositing a metal material such as aluminum or silver with high reflectivity on the entire surface of one side of the glass plate that will be the back surface of the mirror device by a vacuum evaporation method, and increasing its thickness. The transmittance is reduced, and the reflectance is about 93 to 98%.

[0003]

However, when light is radiated to the human body from directly above or behind the human body by a light source such as illumination, the light source irradiates the human body as the human body approaches the mirror device. As the amount of light decreases and the incidence rate of light reflected from the human body and incident on the surface of the mirror device decreases, as a result, the human body projected on the mirror device becomes dark, and brightness is necessary especially when making up the face Is not appropriate. In addition, when light is radiated to the human body from the upper part and both sides of the human body by a light source arranged around the mirror device, unevenness in the amount of light emitted from the light source to the human body as the human body approaches the mirror device. As a result, a bright place and a dark place are extremely likely to occur on the human body projected on the mirror device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and irradiates light toward the human body from the surface of the mirror device even when the human body approaches the mirror device, and projects the human body brightly on the surface of the mirror device. An object of the present invention is to provide an irradiation method, a mirror device using the same, and a vanity table provided with the same.

Means for Solving the Problems and Action / Effect To solve the above problems, the invention according to claim 1 irradiates light toward the human body from the entire surface of the mirror device or the surface of a substantially central portion thereof, thereby providing a mirror device. A mirror device for projecting a human body on the surface of a mirror. By irradiating light from the surface of the mirror device toward the human body, even if the human body approaches the surface of the mirror device, it is possible to prevent a decrease in the amount of light reflected from the human body and incident on the mirror surface, and to place the human body on the surface of the mirror device. We can project brightly. In the case of a portable or stationary mirror device for makeup of the face, the mirror device is often provided with a mirror means large enough to reflect the face or a part thereof, and in this case, the entire surface of the mirror means has a transparent structure. It is preferable to make the entire surface emit light. In the case of mirror means placed on the washbasin or on the vanity stand, considering the productivity, manufacturing cost, and running cost, when the entire human body or upper body is projected on the mirror device, the human body is usually located at some distance from the mirror device. When performing detailed work, such as when the face is placed and when making up the face, the face is close to the surface of the mirror device, so only the central part of the mirror means has a transmissive structure, and the surrounding area is a mirror with excellent reflectance. As a structure,
It is preferable that the substantially central portion of the mirror means emit light. Here, the substantially central portion is a region having a diameter of about 10 cm to 30 cm including at least the center point of the mirror device and having a size equivalent to a human face, and is preferably a width of 20 cm and a height of 30 c.
It is desirable that the area be about m. In addition, when irradiating light from the surface of the mirror device to the human body, the light is irradiated at an irradiation angle of approximately 90 ° to the surface of the mirror device, so that the human body can be projected without any shadow or unevenness. it can.

According to a second aspect of the present invention, there is provided the mirror device, wherein a mirror means having a transmission portion for transmitting visible light from the inside to the outside on the entire surface or substantially at the center, and a light emitting means for emitting light by applying a voltage. And the light emitting means is arranged behind the mirror means located at the transmission part, and the light from the light emitting means is irradiated forward from the mirror means surface. Therefore, even if the human body approaches the surface of the mirror device and the amount of light emitted from the light source such as illumination to the human body decreases, light is emitted from the surface of the mirror device toward the human body by the light emitting means provided behind the mirror means. To illuminate the surface of the mirror device to brightly reflect the human body.

According to a third aspect of the present invention, the mirror device includes light emission control means for controlling a light amount of the light emission means, and the light emission control means causes the light emission means to emit light. As described above, by controlling the light amount of the light emitting means, it is possible to obtain a light amount at which the user can easily see his / her own face in accordance with the use environment and preferences.

The invention according to claim 4 is characterized in that the transmittance of the transmitting portion of the mirror means is in the range of 10 to 50%. If the transmittance of the transmitting portion provided in the mirror means exceeds 50%, the reflectance of the mirror means is low even if the human body is sufficiently illuminated by a light source such as illumination, so that the human body projected on the mirror device is light. Get dark. If the transmittance is less than 10%, the light emitted by the light emitting means is not efficiently radiated forward from the surface of the mirror means, so that if the illuminance of the light emitting means is to be increased, replacement due to early deterioration of the light emitting means, This leads to an increase in power consumption and a drop in economic efficiency.

The invention according to claim 5 is characterized in that the light emitting means is constituted by electroluminescence (hereinafter, EL). A surface (sheet) EL in which a transparent electrode, a phosphor, an insulator, an electrode, and a protective resin sheet are sequentially laminated in a thin film on the surface of the transparent resin sheet is disposed behind the mirror means provided with the transmission portion. Thus, with uniform surface light emission, light can be emitted from the surface of the mirror means to the human body located in front of the mirror device at an irradiation angle of about 90 ° with respect to the surface of the mirror means. In addition, by using EL for the light emitting means, the mirror device can be made thinner and the light emitting shape can be easily formed such as a circle, an ellipse, or a rectangle. Even if it is not provided, light can be emitted from an arbitrary position such as a substantially central portion or a periphery of the substantially central portion. The EL emits little heat during light emission and can efficiently convert electric power into light energy, so that it consumes less power and is more economical. As another light-emitting means, a cold-cathode tube, a fluorescent lamp, or the like can be arranged behind the mirror means, and light can be emitted from the surface of the mirror device toward the human body to project the human body brightly.

According to a sixth aspect of the present invention, the light emission control means includes:

Light can be emitted efficiently. Also,
By varying the voltage and frequency, the illuminance of the light emitting means can be adjusted precisely and easily, so that the user can vary the amount of light emitted from the mirror means with a volume SW or the like according to the use environment or preference. . For example, in the case of a mirror device provided with a sheet-like EL behind the mirror means as a light emitting means, E
The voltage applied to the L electrode is constant, and the frequency is 50-1.
By varying the light amount in the range of 0 kHz, the light amount emitted from the EL is changed, and as a result, the light amount emitted from the transmission part of the mirror means can be varied.

Since there is a possibility of electric leakage, it is preferable to automatically apply a voltage to the light emitting means in consideration of hygiene and safety. For example, when a person stops for more than one second in front of and near the mirror device, a voltage is automatically applied to the light emitting means, and light is emitted toward the human body from the surface of the mirror device, and from the front of the mirror device. When the person leaves, the application of the voltage to the light emitting means is automatically stopped, so that the light emitting means is not forgotten to be turned off, so that waste of power and early deterioration of the light emitting means can be prevented. In addition, an infrared sensor or a distance measuring sensor that can detect the distance between the human body and the mirror means is provided around or near the mirror device, and the light amount of the light emitting means is increased or decreased according to the movement of the human body located in front of the mirror means. By controlling the amount of light emitted forward from the surface of the mirror device, the human body can always be projected brightly on the mirror means.

The invention according to claim 8 is characterized in that there is provided illuminance detecting means for detecting the brightness around the mirror means, and the light quantity of the light emitting means is controlled in accordance with a signal from the illuminance detecting means. . If the area around the mirror device is dim, increase the amount of light emitted from the mirror means toward the human body, and if it is too bright, decrease the amount of light emitted from the mirror means to the human body. By controlling according to the brightness, the human body can be projected on the mirror means while always maintaining a constant brightness. Also, when the mirror device is placed in the washroom, the user may end up with only hand washing even if he is in front of the mirror device. Therefore, when the lighting is not on, the user recognizes that the mirror device is not used and controls so as not to apply the voltage to the light emitting means, or when the water is flowing from the faucet of the washroom even with the lighting. For example, the voltage to the light emitting means may be reduced or stopped.

According to a ninth aspect of the present invention, there is provided a vanity table provided with the mirror device of the present invention. Convenience can be further improved by using together with a light source such as a light bulb or a fluorescent light provided exclusively around the mirror device,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the mirror device according to the present invention will be described below in detail with reference to the drawings. In the drawings described in the present embodiment, the thickness of each member is different from the actual thickness for convenience of explanation. Mirror device 1 shown in FIG.
Is formed by vacuum evaporation on the back surface of the glass plate 6 serving as the mirror means 2, a substantially central portion serving as the transmitting portion 5 has a reflectance of 80% and a transmittance of 20%, and the periphery of the substantially central portion has a reflecting portion. Silver 7 is deposited so that the ratio becomes 95% or more. Behind the transparent part 5 of the mirror means 2, a transparent electrode 12 is provided on a transparent resin sheet 11.
A sheet-like EL, which is sequentially laminated with a phosphor 13, an insulator 14, an electrode 15, and a protective resin sheet 16, which emits white light, is arranged as a light emitting unit 3, and thereafter the whole is covered with an epoxy resin 8. Here, the light emission principle of the EL will be briefly described. When a high voltage (for example, about 100 V) and a high frequency (for example, about 400 Hz) are applied between the transparent electrode 12 and the electrode 15, electrons are emitted from the insulator 14. The emitted electrons collide with the phosphor 13 to emit light, pass through the transparent electrode 12 and the transparent resin sheet 11, and irradiate the surface with light. The light emission control means 4 connected to the light emission means 3 comprises a converter circuit for converting AC to DC and an inverter circuit for converting DC to a variable voltage / variable frequency, and converts a voltage and a frequency supplied from a commercial power supply or a battery. The light is converted efficiently and applied to the light emitting means 3. With this configuration, when a predetermined voltage is applied to the light-emitting unit 3, white light is emitted from the transmission unit 5 provided substantially at the center of the mirror unit 2 to the front of the mirror device 1, The human body located in can be projected brightly.

As the mirror means, the material may be changed between the reflective portion and the transmissive portion, for example, by depositing aluminum on the substantially central portion of the back surface of the glass plate and depositing silver on the periphery thereof. The same effect can be obtained by depositing a low-cost material such as copper and adjusting the transmittance after vapor deposition of a few tens nm. Further, a reflection film is formed on the surface of the glass plate with Sn (tin) or the like, and a light-emitting unit is provided behind a surface mirror having a similar transmission structure, so that even if a human body approaches the surface of the mirror unit, the mirror is formed. It is possible to prevent the occurrence of a double image due to the deviation of the reflection position of the means. In addition, a light emitting means having substantially the same shape as the mirror means having a transparent structure on the entire surface is provided behind the mirror means, and an opening is provided between the mirror means and the light emitting means so as to irradiate only substantially the central part of the mirror means. A mask sheet that blocks the emitted light may be provided. Then, a fluorescent material, an insulator, and an electrode can be directly laminated on the surface of silver deposited on the back surface of the glass plate as the mirror means to integrate the mirror means and the light emitting means. For example, silver is vapor-deposited so that the entire mirror means is transmitted, and silver deposited around the center and its periphery is insulated, and a phosphor,
By laminating the insulator and the electrode, it is easy to switch between the light emission only at the substantially central portion, the light emission only at the periphery of the substantially central portion, and the light emission at the entire surface.

A white phosphor is used for the EL of the light emitting means. However, by stacking phosphors having different emission colors, depending on the user's preference and the surrounding environment, a reddish color generally called a bulb color is obtained. It is also possible to select a warm color or a slightly bluish cold color called fluorescent light color. In addition, light emitting elements such as EL and light emitting diode are arranged in a matrix or
It is arranged in a segment, and when the human body is more than a certain distance from the mirror device, each element is selectively lit to display letters, numbers, pictures, etc. It can also be used as a light emitting display device such as a clock or advertisement . By arranging a heating means such as a planar heating element on the back surface of the EL, heat is transmitted to the mirror means via the EL without obstructing the irradiation from the light emitting means, and the difference between the surface temperature of the mirror means and its surrounding temperature. Fogging of the mirror means surface caused by the above can be prevented. For example, by using the EL electrode as one electrode, a heater circuit serving as a heating means and the other electrode are formed on the surface of the protective resin sheet, and the surface is covered with the protective resin sheet, so that the EL and the heating means are integrated. Therefore, the manufacturing cost can be reduced, and the mirror means can be quickly warmed because the heat transfer coefficient is improved.

By coating the surface of the thin film of silver 7 with a protective resin 8 such as an epoxy resin, corrosion is prevented and
By further covering the surface of L, waterproofness is improved, and it can be installed in places with high humidity such as a washroom.

The light emission control means has an inverter mechanism, and converts the commercial power supply voltage so that the light emission means has a high frequency (for example, 10
When a voltage of 0 Hz or higher is applied, a noise filter circuit is connected in front of the converter circuit provided in the light emission control means to prevent high frequency noise generated when applying a voltage to the light emission means from leaking outside. Prevent erroneous operation of multiple devices. Further, by providing the light emission control means with a timer circuit, it is possible to prevent power consumption due to forgetting to turn off the light emission means. Furthermore, a memory circuit is provided, and irradiation conditions such as applied voltage and frequency when previously used are stored in the memory circuit, and irradiation may be performed under the same conditions at the next use, or a reset circuit may be provided. The irradiation conditions used before may be initialized, and irradiation may be performed in a predetermined initial state at the time of next use.

Since the human body detecting means 22 is provided with a distance measuring sensor 22b for projecting a sensor wave in front of the mirror device 1, it is easy to detect how far the human body is from the mirror means 2 regardless of the presence or absence of a human body. However, since the voltage and frequency to the light emitting means 3 can be changed and the irradiation amount can be changed according to the situation, waste of power is prevented. . For example, the vanity table 21
When there is a person 1 m or more away from the front, there is a high possibility that the vanity stand 21 will not be used. Therefore, no voltage is applied to the light emitting means 3 and the light emitting control means is used when the person approaches within 1 m. By transmitting a signal to the light source 4 and applying a voltage to the light emitting means 5, light may be emitted to a human body located in front of the mirror means 2 with a predetermined illuminance. Further, since the infrared sensor 22b that projects a sensor wave substantially parallel to the mirror device 1 is provided, it is possible to further detect that a human body is approaching the mirror means 2 and increase the illuminance of the light emitting means 3. it can. By arranging the distance measuring sensor substantially in the same plane as the mirror device and projecting the sensor wave in front of the mirror device, it is also possible to control the amount of light of the light emitting device according to the distance to the mirror device. . Further, by using a timer circuit together, it is possible to control such that the light emission is not stopped immediately even if a person moves away from the mirror means for several seconds.

The illuminance of the illumination installed around the vanity 21 is detected by an optical sensor 23 installed above the vanity 21 and the mirror means 2 is used when the surroundings of the mirror device 1 are dim. By controlling the amount of light emitted from the mirror means 2 to the human body in accordance with the brightness around the mirror device 1, for example, increasing the amount of light emitted toward the human body, and decreasing the amount of light when it is too bright. The human body can be projected on the mirror means 2 while always maintaining a constant brightness. In the case of a vanity stand, even if the user is in front of the mirror device, the user may end up with only hand washing. Therefore, when there is no lighting,
When the user recognizes that the mirror device is not used and controls so that no voltage is applied to the light emitting means, or when water is flowing from the faucet even if the lighting is on, the voltage to the light emitting means is reduced or stopped. You may do it.
