According to the present invention, the surface protrudes like a natural stone, and by forming a light-emitting sphere penetrating through the permeable porcelain cover on its own transparent porcelain in a certain pattern, while overcoming the light-transmitting limitation that the porcelain cover has, It can also create an atmosphere that comes out, there is an advantage that can increase the practical value as well as the aesthetic effect.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

First, the manufacturing method of the ceramic illumination cover by this invention is demonstrated.

Basically, as in the conventional light-transmissive ceramic cover manufacturing method, the circular manufacturing step-> formwork manufacturing step-> slip injection step-> demolding step-> firing step.

Therefore, the description of the present embodiment will be described in the general ceramic manufacturing process briefly or omitted the description, and focuses on the difference from the general process.

Circular production step in the present embodiment, as shown in Figure 4, the step (S10) for manufacturing the original plate gypsum or resin; Carving the pattern on the surface of the disc (S20); It is composed of the step (S30) of spraying stone powder on the surface.

Step (S10) of manufacturing the disc from the gypsum or resin is to determine the basic shape of the desired molding, specifically, the gypsum or resin is formed slightly convex on both sides around the pillar and the top of the pillar It is preferable to manufacture a disc such that two sides and the two sides are connected to each other at the edge to have a side of 10 to 12 cm wide.

Herein, resin refers to an amorphous solid or semiconductor composed of an organic compound and derivatives thereof, and especially when a large number of circular pieces are needed or sophisticated pieces are required when engraving a pattern on a disc, a pattern is particularly used by a Computer Numerical Control Machine (CNC) processor. In the case of carving, it is preferable to use resin as a base plate rather than gypsum.

The step (S20) of carving the pattern on the surface of the disc is a step of engraving the pattern on each side formed on both sides of the disc can be automatically done by a CNC machine as well as by designing the graph paper on both sides of the disc by hand You may. At this time, it is preferable to have a depth of about 1 ~ 2mm for digging grooves.

Next, it is preferable to spray fine stone powder on both sides of the disc engraved with a pattern using a stone spray containing a stone powder and adhesive resin (S30). This is to easily attach the stone powder to the surface of the disc to make the surface look like natural stone after molding.

Thus finished plaster surface (caribbean soap) to the finished circular surface repeated two or three times with a soft brush, and then enters the die production step (S40).

Once the mold made of gypsum is dried, it enters a slip injection step (S50).

Here, the ratio of the base to slip is made of 23% by weight of feldspar, 10% by weight of quartzite, 35% by weight of kaolin, 5% by weight of pottery stone and 5% by weight of sericite in consideration of light transmittance. Optionally, it is preferable to further include Bonshes in an amount corresponding to 3 to 4% of the total weight ratio of the components.

However, the ratio of slip possession for light transmission is not limited to the above components and their contents, and of course, may be slightly modified or replaced by other compositions.

It is preferable to remove the slip after a certain period of time so that the base wall is formed to have a thickness of 4 to 5 cm after slip injection in the slip injection step so that a predetermined space is formed between two light emitting surfaces formed in a later hollow step. .

Here, the slip removal time is about 40 minutes is suitable to form the wall thickness of about 4 ~ 5cm, if the slip is removed too soon, the wall thickness is too thin, there is a problem to be hollowed out later, but if removed too late There is a problem that the thickness is too thick, the space between the light emitting surface is narrow, the light is not spread well by the lamp. Of course, the slip removal time of 40 minutes is when the side width between the two light emitting surface is 10 ~ 12cm, the width of the slip removal time can also vary.

Subsequently, after about 1 hour after slip removal, the mold enters the demolding step, and when the moisture content of the molded wall becomes 30-40% after demolding, it is preferable to enter the hollow step (S60).

If the moisture content of the molded conductive wall is too low, not only it is difficult to be hollow, but a lot of cracks may be generated during the work, but if too high, the hollowed out shape may be easily deformed.

It is preferable to remove the cracks and the like generated by hollowing out with a brush before entering the firing step after the hollowing out.

In the hollow step, the pattern already determined in the disc pattern engraving step (S20), which is hollowed out according to the pattern stamped on the ceramic cover formed through the formwork.

The pattern revealed by the hollow step is, as shown in Figure 2, it is preferable that the traditional flower pattern formed by passing through a plurality of light emitting ports 46 regularly.

When the hollow step is completed, go to the firing step (S70), firstly baked for about 1 hour at 900 ° C (first roasting), and after lubricating with white meat, etc., and then firing for 2 hours at 1250 ° C for about 16 hours. By completing the ceramic lighting cover.

Here, between the two light emitting surface of the ceramic light cover, as shown in Figure 3, a narrow space 50 is formed, the narrow space with a ceramic wool before entering the secondary baking (baking) after the first baking (primary roasting) (50) It is preferable to fill the inside. Otherwise, when secondary firing is performed for a long time at a high temperature, light emitting surfaces on both sides may be bent into the narrow space 50 to be stuck together. Of course, the ceramic wool should be removed after the second firing. Ceramic wool can also be replaced with other materials that can withstand secondary firing temperatures.

The surface of the ceramic lighting cover completed through the above steps is protruding like a natural stone, and it is possible to implement traditional flower pattern as it is through the perforated pattern regularly, and can complement the translucent property of the ceramic cover, as well as aesthetic effect There is an advantage to increase the practical value.
