In this case, the holes may be formed very small so that a plurality of holes may be combined to form letters or figures.

In this case, however, foreign matters are inserted into the holes to block the holes, so that light does not penetrate the holes, thereby ultimately changing the shape of the letters or figures, or the characters or figures themselves may be hardly visible.

In addition, even when the light is not irradiated, the hole is exposed to the outside as it is, it may not look good.

The present invention is formed in the light emitting ornaments to form a character or a figure to prevent the foreign matter is inserted into the micro hole to irradiate the light to the outside, and if the light is not irradiated so that the micro hole is not exposed to the outside It is an object of the present invention to provide a light emitting ornament module and a method of manufacturing light emitting ornaments.

As shown in Figure 1 and 2, the light emitting ornament module of the present invention, the base portion 15, the light-transmissive resin 20, and the light source (30).

The base 15 is made of a flat metal material, and a plurality of fine holes 17 penetrated in the vertical direction are formed.

In this case, the plurality of fine holes 17 form letters or figures in the base portion 15.

In addition, the diameter of the fine hole 17 is preferably 0.05 ~ 0.1mm.

That is, the diameter of the micro holes 17 is reduced so that the micro holes 17 are not easily seen by the naked eye.

The fine holes 17 may be arranged in a line to form letters or figures. However, since the diameters of the fine holes 17 are small, the fine holes 17 are arranged in rows to form letters or figures.

In addition, the fine holes 17 are preferably formed in a circular shape using a laser.

The light transmissive resin 20 is inserted and filled in the micro holes 17 to have the same color as the color of the transparent material or the base portion 15.

The light transmissive resin 20 is made of UV paint, solvent and the like.

The optically transparent resin 20 inserted and filled in the plurality of micro holes 17 is inserted into and filled in the micro holes 17 without being adhered to the upper and lower surfaces of the base 15. It is bonded only to the outer peripheral surface of (17).

Therefore, the optically transparent resins 20 respectively filled in the plurality of micro holes 17 are spaced apart from each other without being connected to each other.

In addition, the height of the light transmissive resin 20 filled in the micro holes 17 is equal to or smaller than the depth of the micro holes 17.

As described above, by preventing the light-transmissive resin 20 from being adhered to the upper and lower surfaces of the base portion 15, the metal texture of the base portion 15 made of metal can be expressed as it is. The amount of material, ie, the light transmissive resin 20 can be reduced.

In addition, when the light-transmissive resin 20 is attached to the upper and lower surfaces of the base portion 15, the thickness of the light-transmissive resin 20 increases, so that the fine holes 17 and the light-transmissive resin 20 The transmittance of light to be transmitted is lowered. In the present invention, since the light-transmissive resin 20 is not adhered to the upper and lower surfaces of the base 15, the light filled in the micro holes 17 is the same. Since the thickness of the transparent resin 20 may be reduced, light transmittance may be improved, so that letters or figures may be more brightly expressed to the outside.

In addition, when the light transmissive resin 20 is adhered to the top and bottom surfaces of the base portion 15, the top and bottom surfaces of the base portion 15 and the light transmissive resin 20 over time. The light transmissive resin 20 may be peeled off from the surface of the base part 15 by the difference in the amount of elasticity and the inflow of foreign matter between the contact gaps.

However, in the present invention, the light transmissive resin 20 is not adhered to the upper and lower surfaces of the base 15 and is filled only in the microholes 17, so that the light transmissive resin 20 is the base 15. It can further prevent the separation from.

The light source 30 is disposed at the rear of the base 15 to serve to irradiate light.

The light generated by the light source 30 passes through the light-transmitting resin 20 filled in the microholes 17 and is emitted to the outside to emit light of letters or figures formed by the microholes 17.

When the light transmissive resin 20 is made of a transparent material, since the microholes 17 are so small, the color of the outer circumferential surface of the microholes 17, ie, the color of the base part 15, may be caused by scattering of light. Since it is displayed to the outside through the light transmissive resin 20, the fine hole 17 and the light transmissive resin 20 are not easily distinguished from the outside of the base portion 15 in general.

In addition, when the light transmissive resin 20 is the same color as the base part 15, the micro holes 17 and the light transmissive resin 20 are distinguished from the base part 15 due to the same color. Since it is difficult, the micro holes 17 and the light transmissive resin 20 are hardly distinguished from the outside of the base 15.

For this reason, when the light is not irradiated from the light source 30 at normal times, as shown in FIG. 1, the micro holes 17 and the light transmissive resin 20 are well identified in the base part 15. Since it is not possible, the base portion 15 appears to be free of letters and figures by the fine holes 17.

Then, when the light is irradiated by the light source 30, as shown in Figure 2, since the light is transmitted through the light-transmissive resin 20 to the outside, the shape formed by the fine hole 17 and The figure is exposed to the outside.

Therefore, in the light emitting ornament of the present invention, when the light is not shining, the letter or figure is concealed, and when the light is shining, the letter or the figure appears.

On the other hand, if necessary, the light transmissive resin 20 may have a different color from the base portion 15.

In this case, the letter or figure formed by the light-transmissive resin 20 is normally exposed to the outside, and is more exposed when light shines.

Luminescent ornaments of the present invention as described above are prepared by the following method.

As shown in FIG. 3, the method of manufacturing light emitting jewelry according to the present invention may include a bending step S1, a perforation step S2, a pretreatment step S3, a masking step S4, and an immersion step S5. ), A resin injection step (S6), drying step (S7), separation step (S8), degreasing step (S9), and a post-processing step (S10).

The bending step (S1), masking step (S4), immersion step (S5), separation step (S8) and degreasing step (S9) of the above process is a process that can be selectively added or deleted.

That is, the basic process of the light emitting jewelry manufacturing method of the present invention, the punching step (S2), the pre-processing step (S3), the resin injection step (S6), the drying step (S7), the post-processing step (S10) )

Most preferably, all processes as shown in FIG. 3 are performed.

The bending step S1 is a step of forming the base portion 15 by bending a specific portion of the disc 10 made of metal to protrude downward.

In addition, the drilling step (S2) is a step of forming a plurality of the fine holes 17 penetrating in the vertical direction by using a laser in the base portion 15.

At this time, a plurality of the fine holes 17 are formed to form a letter or a figure.

Of course, since the bending step S1 is a selection process, the perforation step S2 may be performed immediately.

The disc 10 after the bending step (S1) and the punching step (S2) is as shown in FIG.

The pretreatment step S3 is a step of removing burrs generated when the microholes 17 are formed.

The masking step (S4) is a step of attaching a masking member 40 such as an adhesive tape to one surface of the base 15 to close one direction of the microhole 17.

At this time, the masking member 40 is permeable to air, but the liquid is preferably made of a material that does not permeate.

When the base portion 15 is formed to protrude downward in the downward direction by the bending step S1 as in the present embodiment, the base is recessed downwardly in the downward direction. The masking member 40 is attached to one surface of the part 15.

The immersion step S5 is a step of immersing the base portion 15 in which the microholes 17 are formed in the light transmissive resin 20 in a liquid state.

In this case, the depth d1 of the base portion 15 immersed in the transparent resin 20 is greater than the thickness d3 of the base portion 15.

In the immersion step (S5), the other surface of the base portion 15 protruding downwards is in contact with the light transmissive resin 20, and the base 15 is immersed in the light transmissive resin 20. The depth d1 is smaller than the total thickness d2 of the bent disc 10 and larger than the thickness d3 of the base portion 15.

The resin injection step S6 is a step of filling the light transmissive resin 20 in the micro holes 17.

There may be various methods for filling the optically transparent resin 20 in the microholes 17, but the optically transparent resin 20 in the liquid state is filled in the microholes 17 using ultrasonic vibration. It is preferable to.

Since the microholes 17 are too small, it is difficult to fill the optically transmissive resin 20 with the microholes 17. When ultrasonic vibration is used as in the present invention, the optically transmissive resin 20 may be used as the microholes. (17) can be easily filled.

5 (a) and 5 (b) are formed only in the base portion 15 from the beginning without the bending step (S1), in the state in which the masking member 40 is not bonded, contained in the container 50 The base 15 is immersed in the light transmissive resin 20 to show the case where the light transmissive resin 20 is injected into the micro holes 17.

FIG. 5A illustrates a case in which the depth d1 of the base portion 15 immersed in the light transmissive resin 20 is smaller than the thickness d3 of the base, and FIG. 5B illustrates the base portion 15. Is a case in which the depth d1 immersed in the light transmissive resin 20 is greater than the thickness d3 of the base.

In the case of FIG. 5 (a), the light transmissive resin 20 is not sufficiently injected into the micro holes 17, thereby causing a defect.

In addition, in the case of FIG. 5 (b), the light transmissive resin 20 is sufficiently injected into the microholes 17, but the light emitting ornament of the present invention is shown in FIG. 2. It should be filled only in the micro-holes 17, in the post-processing step (S10) to be described later to remove all the light transmitting resin 20 attached to both sides of the base portion 15.

Therefore, there is a disadvantage in that the processing time and processing work in the post-processing step (S10) is increased.

On the other hand, the reason for removing the transparent resin 20 attached to the surface of the base portion 15, the front surface of the base portion 15 in the case of expressing the texture of the metallic material to the outside or other aesthetic appearance In the case of the back of the base portion 15, when the back of the base portion 15 is bonded to another object, the light-transparent resin attached to the back of the base portion 15 is dried ( This is because the contact level may be changed by the height difference of 20), resulting in a poor contact state.

5 (c) is a state in which the masking member 40 is attached to one surface of the base 15, and is immersed in the light transmissive resin 20 as shown in FIG. 5 (b).

In this case, since the masking member 40 covers the whole of one surface of the base portion 15, the disadvantage that the machining time and the machining operation is increased in the post-processing step (S10) as shown in Figure 5 (b) However, when the degreasing step (S9) of removing the masking member 40 from the base part 15 is performed afterwards, an outer circumferential surface of the masking member 40 is applied to the light transmissive resin 20. Attached, there is a disadvantage that the removal of the masking member 40 is not easy.

The immersion step (S5) is most preferably performed as shown in Figure 5 (d).

That is, in the bending step S1, the disc 10 protrudes downward to form the base portion 15 and the micro holes 17, and then downward from the disc 10. The masking member 40 closing one direction of the fine hole 17 is attached to one surface of the recessed base portion 15, and the other surface of the base portion 15 protruding downward is The light transmissive resin 20 is immersed in the light transmissive resin 20 to contact.

In this case, the depth d1 of the base portion 15 immersed in the transparent resin 20 is smaller than the total thickness d2 of the bent disc 10 and the thickness d3 of the base portion 15. To be larger.

Thus, the light transmissive resin 20 may be attached only to the other surface of the base portion 15 and the micro holes 17.

If the masking member 40 is not attached to the masking member 40, the light transmissive resin 20 penetrates through the micro holes 17 and is attached to one surface of the base 15, which is not suitable.

The drying step (S7) is a step of drying the light transmissive resin 20 filled in the micro-holes 17, according to the properties of the light transmissive resin 20 to the natural curing or thermal curing or ultraviolet curing Etc. can be made.

The separating step S8 is a step of separating the base part 15 from the disc 10, and is performed when the base part 15 is separately formed from the disc 10.

In the present embodiment, the base portion 15 protrudes from the disc 10 and is pressed, thereby separating the base portion 15 from the disc 10.

The degreasing step S9 is a step of removing the masking member 40 from one surface of the base part 15 after the drying step S7, and is a necessary process when the masking step S4 is performed.

The post-processing step (S10) is a step of removing the light-transmissive resin 20 attached to the surface of the base portion 15.

In the post-processing step (S10) as described in this embodiment by processing only the other surface of the base portion 15 material is not attached to the masking portion 40, it is possible to reduce the processing time and processing work.

In the post-processing step (S10), it is preferable to perform an anodizing method for forming an oxide film 19 on the surface of the base portion 15 made of a metal.

The separation step (S8), degreasing step (S9) and post-processing step (S10) may be reversed in order.

Luminescent ornaments of the present invention as described above can be used in addition to a variety of accessories, such as signs, buttons, knobs.
