Description

Crystal ornamentation {crystal glass ornarment}

The present invention relates to a crystal ornament having a pattern formed therein by using a laser beam. In particular, the present invention relates to a crystal ornament which can effectively display a pattern formed inside without attaching a colored background portion to one surface of a patterned portion.

The present invention relates to a crystal ornament having a three-dimensional pattern formed therein by laser processing.

In general, crystal glass is a kind of crystal, and is widely used as an ornament which is very hard and transparent and can feel high quality.

Since such a crystal glass has a very high hardness and it is very difficult to process the inside of the crystal glass, the outer surface of the crystal glass is variously processed to form a polyhedron so that the light is reflected to various places.

However, as described above, when only the outer surface of the crystal glass is processed, the shape thereof is extremely limited, so that a crystal decoration of a more various and colorful design can not be obtained. Therefore, a technique of processing a solid pattern inside the crystal glass by laser processing (Korean Patent No. 10-0348419, hereinafter referred to as " Reference 1 ").

The present invention relates to an apparatus for processing the inside of a glass or a crystal glass by using a laser beam, and more particularly to a system for reflecting a laser beam by a mirror rotated in both a lateral direction (X axis) and a longitudinal direction And a pedestal on which the crystal glass is placed is elevated in the height direction (Z-axis) so that the three-dimensional shape can be processed inside the crystal glass.

However, according to the above-mentioned Reference 1, a glass or a crystal glass whose interior has been processed into a three-dimensional shape has a problem that a three-dimensional shape processed in the interior due to the background is not easily seen in a bright place due to the transparent interior.

Therefore, in order to solve the above problem, an illumination device for illuminating a glass or a crystal glass having a three-dimensional shape inside thereof is proposed in Korean Utility Model Registration No. 20-0200229 (hereinafter referred to as "Reference 2").

The above-mentioned Reference 2 is related to a crystal ornament using an illumination device configured to illuminate a crystal ornament having a three-dimensional pattern formed therein by laser processing, as shown in FIG. 1, The plurality of LEDs 30 are mounted on the bottom surface of the coupling groove 21 formed in the coupling recess 21 so that light can be emitted into the interior of the coupling recess 21 through the bottom surface of the crystal ornament 10, The light emitted from the light emitting device 30 emits brightly the solid patterns 10 and 11 formed inside the crystal ornament 10 and the control chip 41 can control the various colors, Which can enhance the visual effect of the crystal ornament.

However, the above-mentioned Reference 2 has an inconvenience that it is necessary to provide a separate case in which the crystal ornaments can be mounted as an invention which does not solve the fundamental problem of the crystal ornaments in which the pattern formed in the crystal glass is not easily seen, , It is an invention having a problem of consuming power at all times in order to obtain a lighting effect.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a crystal glass which is capable of emphasizing a pattern formed inside a crystal glass, It is aimed to provide decorations.

In order to attain the above object, the present invention provides a crystal decorative article comprising a pattern part formed in a three-dimensional shape and capable of engraving a pattern, and a background part adhered to one surface of the pattern part, wherein the pattern part is transparent and the inside is visible, And the color of the background portion is projected when viewed from the other surface of the embossed surface toward the one surface.

According to the present invention, it is possible to obtain the effect that the colored background formed on the inside of the patterned portion can be emphasized by adhering the colored background portion to one side of the transparent patterned portion without a separate illumination device. Further, since the crystal ornament is made of crystal glass having a high appearance and high refractive index, the crystal ornament is easy to be totally reflected, so that the color of the background bonded to the one surface can be clearly seen from any surface of the other surface, It is possible to obtain an effect of obtaining a sense of spaciousness and aesthetics.

In the present invention, in order to provide a crystal ornamental material that can be used to emphasize a pattern formed inside the crystal ornament, by forming a three-dimensional pattern inside the crystal ornament by using a laser beam, Wherein the pattern portion is transparent and the inside portion is visible, and the background portion has a color, and when viewed from the other face of the pattern portion toward the one face, the pattern portion And a color is projected and viewed.

The scope of the present invention is not limited to the embodiments described below, and various modifications may be made by those skilled in the art without departing from the technical scope of the present invention.

Hereinafter, the crystal ornament according to the present invention will be described in detail with reference to FIGS. 2 to 12 attached hereto.

As shown in FIG. 2, the crystal ornament 100 of the present invention includes a transparent pattern 110 having a predetermined thickness and a background part 120 adhered to one surface of the pattern 110.

The patterned portion 110 and the background portion 120 may be a crystal glass. The crystal glass is a glass product called jewel in daily life because it is transparent and crystal clear.

Unlike ordinary glass products, crystal glass is usually blended with lead oxide and potassium carbonate, and has characteristics of high refractive index, heavy weight, beautiful and light impact sound, and excellent abrasion. Since the crystal glass has a high transparency, it does not show color even if the thickness is thick, and is transparent. Also, a glass having a high refractive index for light has a high reflectance and a bright light, so it contains lead oxide, Gloss.

Since crystal glass is rich in workability, it can be cut to increase the effect of high refractive index, and it is excellent in transparency because it does not deteriorate in transparency even when it is thick, so it is an excellent material for high-grade tableware such as glass for crafts and wine glass.

Therefore, it is useful to engrave various patterns 10 or the like as ornaments through a method of locally externally sculpting the crystal glass or locally heating and finely burning the inside using a laser beam to form cracks .

However, in the case where various patterns 10 are inscribed using a laser beam as described above, the pattern 10 and the like are often not clearly seen according to the brightness of the background. 3, when the colored background part 120 is adhered to one side of the pattern part 110 and is viewed from one side of the other side of the pattern part 110, the background part 120, as shown in FIG. 3, The color of the image can be projected. The patterned portion 110 and the background portion 120 are bonded to each other using an adhesive such as an UV bond and the patterned portion 110 and the background portion 120 are formed so as to look like one without interfering with the bond on the bonded portion. It is possible to fabricate an integrated type. Thus, the interior of the background unit 120 can be the background of the background unit 120 without illuminating the backlight. Here, the color of the background part 120 may be various colors, but it is assumed that the colors are black.

FIG. 3 is a plan view showing a shape of a square pillar with the pattern unit 110 and the background unit 120 adhered to each other. Thus, FIG. 3 may be viewed from above, or viewed from the left, right, and bottom.

In the present specification, the arrow indicates the flow of light and may indicate refraction of light or the like.

As shown in FIG. 3, when the pattern part 110 is viewed from the other side opposite to the one side to which the background part 120 is adhered, the pattern part 110 is transparent and the color of the background part 120 is It can be projected. Therefore, the inside of the pattern unit 110 appears to be colored.

At this time, when the pattern 110 is viewed at a certain angle without looking at the center of the other face, the left, right or upper and lower sides of the pattern 110 can be seen. In this case, The light that can be recognized from the eyes that you see is very likely to be totally reflected because it is high.

The index of refraction means that the sine of refraction angle with respect to the angle of incidence is constant. When the wave or light travels from a material having a small index of refraction to a material having a large index of refraction, the frequency does not change, the speed decreases, and the wavelength decreases. That is, as shown in FIG. 4, when the light is refracted at the interface between different media, the ratio of the incident angle to the sine value of the refracting angle is referred to as a refractive index, and the refractive index of light varies depending on the type of the medium and the wavelength . Therefore, as shown in FIG. 4, a part of the light is refracted at the interface between the different media, and another part of the light is reflected with a reflection angle of the same size as the incident angle.

In this case, when light travels from a medium having a large refractive index to a medium having a small refractive index, it is possible to cause total reflection (100% reflection) at the interface when the incident angle is larger than the critical angle. In general, when a medium having a high refractive index is moved to a medium having a low refractive index, a part of the medium is transmitted through the interface and a part of the light is reflected.

However, as shown in FIG. 5, when the angle of incidence is gradually increased, there is no light transmitted when a specific angle is exceeded, and the light is totally reflected at the interface. The incident angle at this time is called a critical angle.

In FIG. 5, 'A' and 'B' rays partially reflect and partially transmit, whereas 'C' does not transmit any rays. When the angle at this time is the critical angle &thetas; and the angle of incidence is the critical angle [theta], the refraction angle becomes 90 DEG. In this case, the critical angle and the refraction angle refer to angles from a virtual normal which is set up vertically at the boundary between the medium 1 and the medium 2.

When the angle of incidence is larger than the critical angle?, The light is totally reflected without the light transmitted through the light 'D', and the incident angle and the reflection angle are equal to each other.

The critical angle? Can be derived by the following equation.

At this time, in the crystal ornament 100 according to the present invention, the inside of the patterned portion 110 in which the light enters the inside from the other side of the patterned portion 110 and is in contact with the left, right and top or bottom faces becomes the medium 1, Or the air in contact with the bottom surface becomes the medium 2 and the left, right and top or bottom surfaces are the interface between the medium 1 and the medium 2, n ₁ is the refractive index of the pattern 110 and n ₂ is the refractive index to be.

I can think that the refractive index of the air is 1.00029 over 0 ℃, 1atm, therefore n ₂ = 1. In order to know the critical angle θ by substituting the above equation, n _1, ie, the refractive index of the crystal material The refractive index is generally as shown in Table 1 below.

matter Refractive index vacuum 1.00 Air (0 ° C, 1 atm) 1.00029 Amorphous crystal 1.46 Glass 1.5 crown glass 1.52 Emerald 1.57 flint glass 1.63 quartz 1.644 Sapphire 1.77 High density glass 1.89 Diamond 2.417

As can be seen from Table 1, the general refractive index of glass is 1.5. In addition, it can be seen that the emblem 110 in the present invention is made to have a refractive index higher than that of the glass, at least the emblem 110 is higher than the refractive index of the glass, Looking at the critical angle,

_{(n 1 = 1.5, n 2} = 1)

sin? = 1 / 1.5? 0.67

θ≈42 °

.

In addition, when the critical angle θ is obtained by using the refractive index of 1.63, which is the refractive index of the flint glass having a refractive index similar to that of the crystal glass,

_{(n 1 = 1.63, n 2} = 1)

sin? = 1 / 1.63? 0.61

?? 37.59

.

Therefore, it can be seen that the critical angle θ is smaller than 42 ° because at least the refractive index of the crystal material is larger than 1.5. When the refractive index is higher, the critical angle θ becomes smaller. In the case of the flint glass, when viewed at an angle larger than 37.59 ° from the normal, Can be confirmed.

That is, when the inside of the pattern unit 110 is viewed, the incidence angle of light hitting the left, right, top, and bottom faces can be totally reflected from an angle smaller than 42 degrees with the normal, It can be seen that the effect of broadening the range in which the total internal reflection occurs can be obtained.

The state of light in which total reflection occurs is as shown in Fig.

When the angle of incidence with the normal line is greater than the critical angle, total reflection may occur, so that the light coming into contact with the wall can be seen as the color of the background part 120. Therefore, when the pattern unit 110 is formed of a crystal glass having a refractive index of 1.5 or more, total reflection occurs on at least one surface of the pattern unit 110 when the pattern unit 110 is viewed from one side of the pattern unit 110 And it is possible to see the color of the background part 120 adhered to the one surface.

In addition, when the pattern unit 110 is formed as a hexahedron, the background unit 120 is adhered to one side of the pattern unit 110. When the pattern unit 110 is viewed from the opposite side of the side to which the background unit 120 is adhered, It is natural that the color of the background part 120 appears to be projected on one side and total reflection occurs on the left side, right side and upper side or bottom side of the inside of the pattern part 110 so that the color of the background part 120 can be seen .

Therefore, when the inside of the pattern unit 110 is viewed from the other side, the color of the background unit 120 may be visible on all the surfaces of the pattern unit 110, The pattern 10 formed inside the crystal ornaments 110 can be seen without any illumination regardless of where the crystal ornament 100 is placed.

As shown in FIG. 7, the embodiment of the crystal ornament 100 according to the present invention may have a quadrangular pyramid shape having a quadrilateral face and a smaller area than the other face, The background portion 120 may be adhered. At this time, it is preferable that the background part 120 is the same size as one surface of the pattern part 110 to be adhered. In the case where one surface is formed as a hexahedron having a smaller area as described above, the longitudinal section of the patterned portion 110 has a trapezoidal shape.

The crystal ornament 100 having the above-described shape has a shape gathered toward one side from the other side when viewed from one side through the other side, so that there is an effect that the sense of space is felt more when the inside is viewed. As shown in FIGS. 8 and 9, it is natural that the color of the bonded background portion 120 is visible on one side when looking at the inside from the other side toward the one side, and all the inside surfaces except the one side, that is, left side, right side, The color of the background portion 120 can be seen to be apparent by total reflection of the lower surface and the lower surface so that the three-dimensional pattern 10 engraved inside the crystal can be formed in the space and the background You can see it well without being distracted by it, and you will feel more sense of space.

A photograph showing the above embodiment will be described with reference to FIGS. 10 to 12 as follows.

FIGS. 10 and 11 are photographs of the embodiment of the present invention viewed from the side and top, respectively, and FIG. 12 is a photograph of the embodiment of the present invention viewed from the front.

The present invention may include a pattern unit 110 and a colored background unit 120 coupled to the pattern unit 110. At this time, as shown in FIGS. 10 and 11, the patterned portion 110 is made of transparent crystal, and light can be seen through the back of the ornament. However, when the present invention is viewed from the front as shown in FIG. 12, the left and right side surfaces 111 and 112, the upper surface 113, and the lower surface 114 as well as the portion to which the background portion 120 is adhered, It can be confirmed that the color of the background part 120 is visible. In addition, when the background part 120 is black, the pattern 10 engraved on the pattern part 110 has a white line, and thus, a more esthetic effect can be obtained.
