Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Technical Field] The present invention relates to a lighting cover attached to a lighting box attached to a mirror such as a vanity.

[Prior Art] A lighting box including a ball lamp and a fluorescent lamp is provided around a makeup mirror of a vanity. These luminaires are structured so that the illuminance is appropriate and the position of the light source is devised so that the face of the user can be easily seen.

The illumination box generally has a fluorescent lamp or the like as a light source, and a translucent cover made of synthetic resin or the like on the front surface thereof. By providing such a cover, the atmosphere at the time of certification can be created, and an optimal illumination space for makeup and the like can be created. In addition, in particular, in a bathroom vanity and the like, in order to improve the color tone during makeup, an incandescent lamp or the like is used in place of the fluorescent lamp, and illumination such as a combination of a fluorescent lamp and these light sources is often adopted.

[Problems to be solved by the device]

Since the amount of heat generated by a fluorescent lamp is relatively small, there is no problem even if the lighting box is closed with a cover. However, incandescent lamps generate much more heat than fluorescent lamps. For this reason, when the inside of the illumination box is closed by the cover, hot air stagnates and the internal temperature rises.

On the other hand, a cover, a makeup mirror body, and the like are mainly made of a synthetic resin sheet, and the makeup mirror body is often a wooden product. Such a material is affected by the temperature rise in the lighting box due to hot air, and in the case of synthetic resin it is deformed or distorted if it is thermoplastic, while it is carbonized if it is a wooden makeup mirror body. . For this reason, the cover may come off from the main body of the makeup mirror or the strength of the tree may be reduced, which may cause a situation in which the cover cannot be used. In addition, if a wattage greater than the specified wattage is incorporated, the amount of heat generated will increase dramatically, resulting in severe deformation and the like.

As mentioned above, when a light source with high heat generation is adopted,
There is a problem that various obstacles occur when the interior of the lighting box is a closed space.

Therefore, an object of the present invention is to provide a ventilation structure for a lighting cover to prevent retention of hot air, prevent deformation and carbonization of the cover, and enable complete use.

[Means for Solving the Problems]

The present invention is a lighting cover incorporated as a light projecting surface of a vertically arranged lighting box in which a light source is arranged, and has an operation section in which a switch, a cord and the like are arranged at the lower end and the upper end is opened. The operation portion is provided with a ventilation hole whose lower end is open to the outside air and whose upper end is opened to the storage side of the light source, and which accommodates the switch, the cord wiring, and the like, with respect to the air flow passing through the ventilation hole. It is characterized in that a chamber capable of shielding electrical equipment is provided.

[Action]

When the light source inside the lighting cover is turned on, the internal temperature rises due to the heat generated. On the other hand, if the upper and lower parts of the lighting cover are open to the outside air, a convection phenomenon occurs due to a temperature rise, and air flows into the inside from the lower open part, rises, and is discharged from the upper open part. .

In addition, even if an operating portion is provided at the lower end of the lighting cover and the switch cord wiring is provided on the operating portion, by providing the chamber so that these electric devices are not exposed to the air flow,
It is possible to protect electrical equipment.

〔Example〕

FIG. 1 is a front view of essential parts showing an example in which the lighting cover of the present invention is incorporated in a makeup mirror body of a vanity.

In the figure, the makeup mirror main body 12 is arranged to stand up from a cabinet (not shown) of a vanity, and is installed by connecting the lower end to the back guard of the washbasin.

The makeup mirror main body 12 is provided with a back plate for fixing the mirror M to the front surface thereof, and illumination boxes 13, 14, 15 are provided around the mirror M, and one illumination box 14, 15 is arranged in the left and right arrangements. Fluorescent light 2
It incorporates one and two incandescent lamps 22, respectively. It should be noted that one fluorescent lamp can be placed in the upper illumination box 13, and another illumination box may be provided at the lower end of the mirror M.

The vertically arranged illumination boxes 14 and 15 are configured by enclosing a fluorescent lamp 21 and an incandescent lamp 22 by an illumination cover provided on the front surface thereof, and illuminate a person standing in front of the mirror M as indirect illumination. Further, the illumination box 13 at the upper end is also provided with a box-shaped illumination cover 13a. The lighting cover 1 is a translucent material made of a thermoplastic synthetic resin, and has a front surface and a surface facing the mirror M which are cross-sectional light projecting surfaces orthogonal to each other.
The entire upper end surface is opened to the outside.

At the lower ends of the illumination boxes 14 and 15, there is provided an operation unit 5 having a built-in switch, a conset or the like.

The operation part 5 on the right side incorporates a switch, and a casing using a synthetic resin sheet as shown in FIG. 2 (a).
5a is fixed so as to bite into the lower end of the lighting cover 1. The upper and lower parts of the casing 5a have ventilation holes 5b, 5
By opening c, the lower part of the lighting cover 1 is opened to the outside by these, and an air flow path is provided. A bottom view of the casing 5a is shown in FIG. Further, inside the casing 5a, there is integrally provided a chamber 5d in which the switch 6a, the cord 6b and the like are partitioned and stored so as not to come into contact with the outside air. As shown in FIG. 4, the chamber 5d is provided at a substantially central portion of the casing 5a so that air can flow from the ventilation hole 5c on the bottom surface to the ventilation hole 5b on the upper surface.

On the other hand, the operation section 5 on the left side is used to mix and store the conset, and as shown in FIG. 2 (b), the outlet 6c is arranged on the front surface of the casing 5a, and the outlet cover which can be opened and closed to cover the surface is further provided. 6d is provided. Also, since the back of the outlet 6c and the cord 6b are housed inside the casing 5a, a chamber similar to the operation unit 5 on the switch 6a side is housed.
5d is formed.

In the above configuration, the fluorescent lamp 2 in the lighting box 14, 15
Even when 1 or the incandescent lamp 22 is turned on, hot air does not stay due to the vent holes 5b and 5c provided in the operation portion 5 at the lower end of the lighting cover 1 and the open structure of the upper end of the lighting cover 1. That is, although the heat generated by the incandescent lamp 22 is large, the lighting boxes 14, 1
A convection phenomenon occurs as the internal temperature of 5 rises, and air flows away from the vent holes 5b and 5c at the lower end toward the open end at the upper end of the lighting cover 1. For this reason, the lighting box 14,1
The rise in the internal temperature of 5 is suppressed, the heat influence on the lighting cover 1 and the makeup mirror body 12 around it is small, and the deformation and carbonization of the members are prevented. Therefore, even if a light source such as an incandescent lamp that generates a large amount of heat is used, the illumination boxes 14 and 15 and the members around them can be maintained, and the product can be supplied as a product with improved durability. Further, since the incandescent lamp 22 and the like can be used, it is possible to create a color tone more than the illumination of the fluorescent lamp 21 alone, and it can be suitably used for makeup and the like. Furthermore, the lighting cover 1
Since the surface temperature of the product can be controlled, you will not be injured by touching it.

In addition, a switch 6a and a conset 6c are provided on the lower end of the lighting cover 1.
Even if the operation unit 5 such as the above is provided, the rise of the internal temperature of the lighting cover 1 is suppressed by the vent holes 5b and 5c. Since the switch 6a and the outlet 6c in the operation unit 5 are housed in the chamber 5d, they do not come into direct contact with the air flow. For this reason, even if moist air passes through the casing 5a when the face or hair is washed using the vanity, the electric device is not damaged.

Here, the illumination cover 1 has its lower end placed on the upper surface of the casing 5a of the operation portion 5 as shown in FIG.
As shown in the figure, the fixture 7 can be used to restrain and fix the makeup mirror body 12. FIG. 6 (a) shows a perspective view of the fixture 7 for the lighting cover 1 arranged on the right side in FIG.

The fixture 7 is made of a thin metal plate, and has a base 7a with screw holes 7b for fixing it to the upper surface of the makeup mirror body 12, and two arms 7c protruding forward from both ends of the base 7a. There is. The tip of each arm 7c is formed as a restraining piece 7d that is bent downward, and a guide piece 7e that extends obliquely downward toward the front side is provided at the lower end thereof.

On the other hand, in the illumination cover 1, both ends of the back portion are bent inward to have an attachment margin 1h, and the bent portions are restrained by restraining pieces 7d at the tips of the two arms 7c. Further, as shown in FIG. 6B, the fixture 7 has a base 7a placed on the upper surface of the makeup mirror body 12 and is fixed to the makeup mirror body 12 with screws 7f. At this time, there is a gap between the front surface of the makeup mirror body 12 and the plane of the restraining piece 7d so that the lighting cover 1 can be inserted. The same applies to fixing the illumination box 1 arranged on the left side, and the illumination box 1 is fixed to the makeup mirror body 12 by a fixture 7 formed symmetrically to the one arranged on the right side.

The lighting cover 1 is incorporated in such a manner that the mounting margin 1h at the upper end thereof is inserted into the gap between the restraining piece 7d and the makeup mirror body 12. That is, the lower end side of the lighting cover 1 is attached to the makeup mirror main body 112.
Set the tilted position away from the side, and attach the installation fee 1h to the guide piece 7e.
Slide it on the back side of the and insert it between the restraint piece 7d and the makeup mirror body 12. When the lower end of the lighting cover 1 is placed on the casing 5a of the operating portion 5 as shown in FIG.
Is restrained and fixed by elastic deformation of the restraint piece 7d.

As shown in FIG. 6 (b), since the distance between the fixing point where the fixture 7 is fixed by the screw 7f and the restraining piece 7d is large, the lighting cover 1
When the plug is inserted in an oblique posture, the fixture 7 is easily elastically deformed so as to warp upward. Therefore, even if the lighting cover 1 is inserted in an oblique posture, the fixture 7 is not broken and can be securely fixed. In addition, in the case of removing the lighting cover 1, once it is pulled up a little and pulled toward you, the mounting allowance 1h is pulled out from the fixture 7 and can be easily removed.

In this way, the upper end of the lighting cover 1 can be detachably attached to the fixed portion 7.
The lighting cover 1 can be easily attached and detached as compared with the case where the lighting cover 1 is fixed by using screws. Therefore, it is convenient to replace the fluorescent lamp 21 and the incandescent lamp 22 and the like, and it is also effective to reduce the cost by reducing the number of members.

In the embodiment, the makeup mirror main body of the vanity is explained, but it goes without saying that the present invention can be applied to other lighting equipment.

[Effect of device]

In the present invention, the upper and lower parts of the lighting cover are opened to the outside air, and the convection due to the heat generation of the light source is used to allow the air to be discharged from the bottom to the top. Therefore, the rise in the internal temperature of the lighting cover can be suppressed, the deformation and carbonization of the member made of synthetic resin or wood can be prevented, and the durability can be greatly improved. Further, since an incandescent lamp or the like having a relatively large calorific value can be used, it is possible to bring out a color tone as compared with an illumination using only a fluorescent lamp, and it can be optimally used for makeup or the like.

Further, since the operation part is provided with a chamber so that the switch, the cord wiring and the like are not exposed to the air flow, the electric equipment is surely protected and it can be suitably used as equipment for washing the face and hair.
