Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-fog mirror with a damp-proof lighting device for use in places such as bathrooms where humidity is high and the mirror surface tends to become cloudy.

[0002]

[Prior art]

 The surface of a mirror in a humid place such as a bathroom becomes cloudy immediately. Therefore, it has been proposed to place a heat source on the back of the mirror so that it will not become cloudy. Further, in order to improve the image of the object to be reflected on the mirror, many mirrors provided with an illuminating device that illuminates the front part of the mirror have been proposed. However, it would be wasteful if the lighting device and the device for only the anti-fog were provided separately, so a mirror having both is proposed.

As disclosed in Japanese Utility Model Publication No. 59-1561, a light source (incandescent lamp) is installed on the back surface of a mirror, and a ring-shaped lens is arranged around the light source so that light from the light source is emitted. It is flat or spindle-shaped, and the light of the light source is emitted to the surface of the mirror by a prism or a reflecting mirror, which is used for illuminating the object to be imaged, and the heat of the light source prevents fog.

[0004]

[Problems to be solved by the device]

 The above-mentioned mirror having both anti-fog and lighting has various drawbacks in actual use. That is, since an incandescent lamp, which is a point light source, is used as the light source, a ring-shaped lens is required to efficiently guide the light to the mirror surface, and planar reflection is required for emission to the mirror surface. Since a prism is used and the light source is a point light source, the illumination light is close to parallel light. For this reason, it is not possible to uniformly and brightly illuminate a subject close to the mirror, and it is necessary to increase the amount of light from the light source to illuminate the subject uniformly and simply by diffusing parallel light. Furthermore, if an incandescent lamp is installed in the rear space of the mirror, the rear space becomes thicker, which is inconvenient for installation in a bathroom or the like. In addition, incandescent lamps generate too much heat, and the heat-generating part also serves as a point heat source, causing damage to the vicinity of the incandescent lamp due to aging, which is a problem with the durability of the mirror itself. Further, in order to solve the above-mentioned problem of parallel light, when the light amount of the light source is increased, the amount of heat generation is further increased. Therefore, there are various inconveniences to the light source and the reflection plate in the conventional mirror with an illumination device. It is hard to say that it is an anti-fog lighting device suitable for mirrors.

Therefore, the present invention proposes a specific structure suitable for an anti-fog mirror with a moisture-proof lighting device that illuminates an object with a back light source of the mirror and prevents fog on the mirror surface.

[0006]

[Means for Solving the Problems]

 The anti-fog mirror with a moisture-proof lighting device according to the present invention comprises a mirror body having a flat closed space on the back surface and a light transmission part provided at an appropriate place on the surface, and a fluorescent lamp installed in the back closed space of the mirror body. The rear surface of the light-transmitting portion is composed of a reflector plate that spreads and reflects the light of the fluorescent lamp toward the center of the front surface of the mirror body.

[0007]

[Action]

 When the fluorescent lamp is turned on, the light is reflected by the reflection plate and emitted from the light transmitting portion, and illuminates the object in front of the mirror. At this time, the emitted light is diffused toward the center of the front surface of the mirror body by the reflection plate, so that the object is illuminated brightly and uniformly. Also, by turning on the fluorescent lamp, the sealed space on the back side of the mirror body is warmed and the temperature of the mirror body itself is raised to an appropriate temperature, which prevents the mirror body from becoming cloudy.

[0008]

【Example】

 Next, an embodiment of the present invention will be described. The anti-fog mirror with a moisture proof lighting device according to the present invention comprises a mirror body 1, a fluorescent lamp 2, a reflector 3 and a rear space forming portion 4 of the mirror body 1, and the mirror body 1 is a front surface of the rear space portion 4. It has a large size to block the light and has a mirror section 11 for projecting a subject and a light transmitting section 12 for emitting the illumination light on the surface. The light transmitting section 12 is formed in the shape of a polished glass that softens the emitted light. To do. The fluorescent lamp 2 is fixed to the back space portion 4 and is provided with appropriate electric wiring. The reflection plate 3 is provided at a position corresponding to the light transmitting portion 12, and has a bulging surface or a bent surface so that the light of the fluorescent lamp 2 is diffused through the light transmitting portion 12 toward the front center of the mirror body 1 and reflected. Alternatively, it is a combination of several bulging and bent surfaces.

Further, the black body coating 13 is formed on the back surface of the mirror portion 11, and an appropriate reflection plate 41 is provided on the wall surface of the back space portion 4 to enhance the utilization efficiency of light and heat. Then, the back space 4 provided with the fluorescent lamp 2 and the reflector 3 is fixed to a mirror installation place in the bathroom, and the front of the back space 4 is hermetically closed by the mirror body 1 before use. It lights up the lamp 2 and functions as lighting and anti-fog as will be described later by turning on the lamp 2. The closed space 4 can be made thinner than the conventional anti-fog mirror with a moisture-proof lighting device using an incandescent lamp. Also, it can be easily installed in the bathroom, etc., and since the sealed space is sealed, there is no concern about leakage.

Next, the function of preventing fog will be described. When the fluorescent lamp 2 is turned on when the mirror is used, its calorific value is much weaker than that of an incandescent lamp, but since the sealed space 4 is small, the air temperature inside the sealed space 4 is high even when the fluorescent lamp 2 generates heat. Therefore, the surface temperature of the mirror body 1 can be raised to the room temperature or higher outside. Therefore, the lighting of the fluorescent lamp 4 does not cause dew condensation on the surface of the mirror body 1 due to moisture in the bathroom. Furthermore, even if water droplets adhere to the surface of the mirror body 1, it will be dried by the heat of the mirror body 1 and the mirror can be used in the bathroom or the like without any trouble.

Explaining the illumination, when the mirror is used, the fluorescent lamp 2 is turned on, and the light is reflected by the reflection plate 3 and emitted from the light transmission section 12. Since the reflecting plate 3 has a predetermined bulging surface, a bent surface, or a combination of both, the emitted light A is emitted while being diffused to the center side of the front surface of the mirror body 1, and the light is prevented from becoming parallel light. Further, the light is softened by the scattering surface of the light transmitting portion 12, and the subject standing in front of the mirror body 1 is illuminated brightly and uniformly. Furthermore, since the location where the fluorescent lamp is installed is sealed, it is possible to prevent moisture from entering the bathroom, and there is no risk of electrical leakage.

The present invention is not limited to the above-described embodiment, and a fluorescent lamp may be a rod-shaped fluorescent lamp 2a as shown in FIG. 3, and the reflector is also as shown in FIG. The reflection plate 3a having a mixture of the bent surface and the curved surface may be used, and further, the light transmitting portion 12a may be formed in a pattern as shown in FIG. Of course, the rear space portion 4 may not be an independent member but may be formed directly on the wall surface of the installation location.

[0013]
