Description

Manufacturing method of lamp cover {MANUFACTURE METHOD OF COVER FOR LAMP}

The present invention relates to a manufacturing method of a lamp cover, and more particularly, to express a natural pattern and shape on the inner surface of the cover to make the aesthetics of the lamp cover more beautiful, and to form a coating layer on the inner surface. It relates to a method of manufacturing a lamp cover so that the expressed pattern or shape is not easily deformed and discolored.

In general, the lamp cover is used to protect the lamp, as shown in FIG. 1, to not only make the illumination by the lamp indirect lighting, but also to show the effect of the interior design, such a lamp cover, various interior atmosphere It is manufactured in various forms for the production of.

As a material of the above-mentioned lighting lamp cover, various materials such as glass, paper, and fabrics are generally used. Among these materials, glass has been widely used due to the fact that glass is not flammable and that the material is simple. For this reason, transparent glass is not used as it is. That is, in order to take advantage of scattering or refraction of the light itself, a translucent one is used or provided in a three-dimensional pattern.

In addition, a lamp cover made of Hanji is used to create a traditional and subtle indoor atmosphere. The cover of the Hanji lamp is made of a predetermined rectangle and is directly applied to the outside of the bulb. Hanji lamp cover of the same way there is a risk of fire, there is a problem, as well as the Korean paper itself changes yellow, there is a problem that must be replaced frequently.

In addition, as another example, by attaching hanji to the inside of the lamp cover manufactured using transparent glass, it is possible to obtain a subtle indirect lighting effect through the hanji, but in this case, the hanji is discolored. Of course, there are a number of problems, including the hassle associated with this.

Therefore, the use of Hanji itself as a method for producing the Hanji pattern effect of the lamp cover as described above is because the Hanji itself is exposed to heat and can be easily discolored by heat or other dust. It is difficult to expect long-term effects.

On the other hand, in order to solve the above problems, Utility Model Registration No. 183365, "Hanji pattern lamp cover glass" has been proposed.

This is formed by a smear of the paint made by a predetermined brushing operation applied to the surface of the lamp cover glass before the paint trapped on the surface of the lamp cover glass dries, and the Hanji pattern is a plurality of spaced apart at a narrow interval. In addition, the hanji pattern is made of a plurality of intersections extending in different directions to have a predetermined angle.

The conventional Hanji pattern lighting lamp glass cover configured as described above, as the Korean traditional Hanji pattern is irradiated indoors by the light of the lamp, the user is warm, not only can enjoy the old emotions, but also by frequent cleaning Eliminate the hassle and reduce the cost of replacement by contamination.

However, it is difficult to form hanji pattern by brushing brush on the surface of the lamp cover, and in the case of long-term use, the paint forming the hanji pattern is discolored by the heat emitted from the lamp and must be replaced with a new one. In addition to the inconvenience, there is a problem such as an additional cost.

The present invention has been made to solve the problems of the conventional lamp cover as described above, but expressing a natural pattern or shape on the inner surface of the lamp cover, by forming a coating layer further, the pattern or shape expressed during long-term use discolored Not only to prevent, but also to provide a manufacturing method of the lamp cover to facilitate the operation of expressing the pattern by inducing the applied paint flows while melting.

10: lamp cover 11: body

12: pattern layer 13: coating layer

The manufacturing method of the lamp cover of the present invention to achieve the above object,

After the solid pigment is mixed with the liquid pigment, the coloring step of spirally coloring the mixed pigment along the inner peripheral surface of the lamp cover body,

As the pigment colored on the inner surface by the coloring step is dried, the pattern expression step of expressing the pattern by flowing the thinner again on the solid pigment solidified;

A first drying step of drying the pattern represented by the pattern expression step,

A coating step of forming a coating layer by applying a curing agent to an inner surface of the lamp cover dried by the first drying step;

Characterized in that the secondary drying step of drying the lamp cover formed with the coating layer for a predetermined time.

The manufacturing method of the lamp cover of the present invention having the above characteristics, not only can easily express the pattern on the inner surface of the lamp cover, but also by further forming a coating layer to protect the expressed pattern, thereby preventing discoloration and discoloration of the expressed pattern. As a method of preventing and expressing a pattern is naturally expressed by a flowing stain of paint without using a brush or a brush, there is no difficulty in expressing various patterns and shapes.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings for the manufacturing method of the lamp cover.

Figure 2 is a schematic view showing a manufacturing process of the lamp cover according to the present invention, the inventors of the manufacturing method of the lamp cover, the coloring step, the pattern expression step, the first drying step, the coating step and the second drying step When made, it will be described the manufacturing process of the lamp cover manufactured accordingly as follows.

First, the pigment contained in the primary coloring tool is squeezed onto the inner surface of the lamp cover body 11 by using the primary coloring tool 20 having the coloring part 21 extending on one side.

In coloring the inner surface of the lamp cover 10, the body 11 of the mixed pigment contained in the primary coloring tool 20, by slowly rotating the body 11 in one direction as shown, the colored The pigment is colored evenly and spirally on the inner surface of the body 11. At this time, the colored portion is not part of the entire inner surface of the body, that is, the colored portion is to be uniformly colored in an spiral shape on the inner surface of the body while maintaining the band shape.

In addition to the primary coloring tool, the pigment may be colored on the inner surface of the body using a brush such as a brush.

After the pigment is colored to have a band shape on the inner surface of the body using the primary coloring tool as described above, and before the colored pigment is completely dried, the secondary coloring tool 30 is used on the applied pigment. Makes the thinner flow

The secondary coloring tool, it is preferable to achieve the object of the present invention that the end portion of the coloring portion is thinner than the primary coloring tool, it is the first coloring using the secondary coloring tool 30 in this way When the thinner flows on the pigment, the body 11 is slowly rotated in one direction as in the primary coloring.

When the body is slowly rotated while the thinner flows on the primary colored pigment as described above, the pigment applied by the flowing thinner flows downward, giving a feeling of acidification as if stained.
