도광판은 각종 디스플레이 제품이 많이 사용되는 것으로 광원에서 나오는 빛을 효율적으로 전달 및 적절히 분산시켜 주는 역할을 하는 판넬 형상의 구조로 이루어진다. 근래에는 이러한 도광판의 하부에 광원으로서 엘이디를 장착한 구조의 것이 많이 나오고 있다. The light guide plate is widely used in various display products, and has a panel-like structure that serves to efficiently transmit and disperse light from a light source. In recent years, many of the structures in which LEDs are mounted as a light source under the light guide plate have emerged.

이때 빛의 전달과 산란을 효과적으로 이루어지게 하기 위해 엘이디가 수용될 수 있는 홈을 도광판 하부에 형성하고 그 상부 면에도 대응하는 오목한 홈을 형성한 구조의 도광판이 나오고 있다At this time, in order to effectively transmit and scatter light, a light guide plate having a structure in which an LED can be accommodated is formed in a lower part of the light guide plate and a concave groove corresponding to the upper surface thereof is provided.

이러한 종래 도광판의 경우, 도 1 에서 보듯이, 도광판 상부면의 오목한 렌즈면을 금형으로 사출 성형하되, 2차로 이 오목한 홈에 각이 형성된 면가공부(40)가 형성되게 하였다. 즉, 상면의 홈은 구면이 아니라 여러 단계의 각이진 형상의 면가공부(40)가 연속되게 이어져 오목한 홈을 형성하게 된 것이다In the conventional light guide plate, as shown in FIG. 1, the concave lens surface of the upper surface of the light guide plate is injection molded into a mold, and the surface processing part 40 having an angle formed in the concave groove is secondarily formed. That is, the groove on the upper surface is not a spherical surface, but the surface processing portion 40 of the angular shape in various stages is continuously formed to form a concave groove.

이렇게 2차적인 가공을 하는 이유는 각이 진 오목한 형상으로 만들면 빛의 분산 효과를 더 높여주기 때문이다. 따라서 그 면 가공이 매우 어렵다The reason for this secondary processing is to make the angle of concave shape to enhance the light scattering effect. Therefore, the surface machining is very difficult

또한 1차로 오목한 형상의 홈을 형성하기 위한 성형용 금형을 제작하여 사출성형 가공한 후, 2 차로 면가공 하므로 생산 속도가 느리고 금형 가공 설비가 갖추어져야 하는 등의 설비면에서 여러가지 어려운 점이 많이 있다
In addition, there are many difficulties in terms of equipment, such as slow production speed and mold processing equipment, since the molding die for forming the first concave groove is manufactured and injection molded after the injection molding.

본 발명은 상기한 점을 감안하여 발명한 것으로, 가공이 간단하고 용이하며 사출 성형을 위한 사출성형시설이 불필요하고 제품의 양산 속도를 크게 높일 수 있는 구조의 도광판을 제공함에 본 발명의 목적이 있다SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object of the present invention is to provide a light guide plate having a structure that is simple and easy to process, does not require an injection molding facility for injection molding, and can greatly speed up the mass production of a product.

이하, 상기 목적 외 다른 목적을 추가로 설명한다
Hereinafter, another purpose other than the above will be further described.

상기 목적을 달성하기 위한 본 발명의 주요 구성은, 상,하면에 오목한 렌즈 형상의 홈을 갖는 렌즈형 도광판에 있어서, 상기 렌즈형 도광판의 상면에 형성되는 홈의 위치 중앙에, 수평한 면으로 이루어지는 수평면부(30)를 형성하고, 그 주변은 볼록한 면으로 이루어지는 볼록부(35)를 형성한 것을 특징으로 하며, 상기 수평면부(30) 및 볼록부(35)는 엔드밀(33)에 의한 가공으로 형성하는 것을 특징으로 하며, 상기 엔드밀(33)은 그 하단부는 렌즈형도광판(1)의 수평면부(30)에 상응하는 돌출된 구조의 수평부(34)를 가지며, 그 수평부(34) 주변 외측으로는 볼록부(35)에 대응하는 오목한 형상을 갖는 것을 특징으로 한다The main constitution of the present invention for achieving the above object is a lens-shaped light guide plate having a lens-shaped groove concave on the upper and lower surfaces, wherein the groove is formed in a horizontal plane at the center of the position formed on the upper surface of the lens-shaped light guide plate. The horizontal surface portion 30 is formed, the periphery thereof is characterized in that the convex portion 35 is formed of a convex surface, the horizontal surface portion 30 and the convex portion 35 is processed by the end mill 33 The end mill 33 has a lower end portion having a horizontal portion 34 having a protruding structure corresponding to the horizontal surface portion 30 of the lenticular light guide plate 1, and the horizontal portion 34. ) Has a concave shape corresponding to the convex portion 35 on the outer side.

또한 본 발명은 상기 렌즈형 도광판의 하면에 형성되는 홈(3)의 위치 중앙에, 원추형으로 이루어지는 원추홈면(50)을 형성하고, 그 외주는 단면상 단턱이 진 단턱부(51)를 형성한 것을 특징으로 하며, 상기 하면에 형성되는 홈(3)은 엔드밀(33)로 가공하되, 엔드밀(33)은 원추홈면(50)과 단턱부(51)의 형상으로 가공할 수 있는 상응되는 형상을 갖는 것을 특징으로 하며, 또한 상기 렌즈도광판(1)은 절취부(55)를 형성하여, 홈(3)이 가공된 각각의 렌즈도광판편(56)으로 분리하여, 이를 조명용 판넬(57) 후방에 설치할 수 있도록 구성한 것을 특징으로 한다
In addition, the present invention is to form a conical groove surface 50 of the conical shape in the center of the position of the groove (3) formed on the lower surface of the lens-shaped light guide plate, the outer periphery of the stepped portion 51 having a stepped end in cross section Characterized in that, the groove 3 formed on the lower surface is processed into an end mill 33, the end mill 33 is a corresponding shape that can be processed into the shape of the conical groove surface 50 and the stepped portion 51 In addition, the lens light guide plate (1) forms a cutout portion (55), the groove (3) is separated into each lens light guide plate piece (56) processed, this is the rear panel for illumination 57 It is characterized by being configured to install in

본 발명에 의하면, 엔드밀에 의한 렌즈도광판(1)의 오목 홈을 직접 가공으로 가공이 매우 간단하고 용이하다.According to the present invention, the concave groove of the lens light guide plate 1 by the end mill is directly processed, which is very simple and easy.

또한 도광판에 오목홈을 형성하기 위한 도광판의 사출 성형장치를 별도로 갖출 필요가 없어 도광판 생산 시설비를 매우 크게 절약한다In addition, there is no need to provide a separate injection molding apparatus for the light guide plate to form concave grooves in the light guide plate, thereby greatly reducing the cost of manufacturing the light guide plate.

또한 사출 성형을 위한 금형 및 그 장치는 많은 비용과 시설비와 운영관리비 및 설치 면적을 필요하므로 그 비용 절감 효과는 매우 지대하다도 할 수 있다In addition, since the mold and the apparatus for injection molding require a lot of cost, facility cost, operation and maintenance cost, and installation area, the cost reduction effect can be very large.

또한 본 발명에 의하면 도광판 사출 성형 후 2 차적인 면가공이 불필요하여 제품의 양산 속도를 높이고 제조 공정을 단축하고 2차 가공시설도 불필요하며 생산 속도도 매우 빠르다In addition, according to the present invention, the second surface processing is unnecessary after the light guide plate injection molding, thereby increasing the mass production speed of the product, shortening the manufacturing process, requiring no secondary processing facilities, and producing a very fast production speed.

또한 분리가능한 렌즈도광판편(56)을 이용하여 광고 조명용 판넬(57)의 외형상에 맞추어 판넬(57) 후방에 부착하거나 설치하고 렌즈도광판편(56) 후방에 엘이디를 설치하면 종래의 광고 판넬의 구성보다 엘이디(4) 조명을 적게 사용하고도 균일한 휘도와 밝기를 줄 수 있다In addition, by using a detachable lens light guide plate piece 56 to attach or install the rear of the panel 57 in accordance with the appearance of the advertising lighting panel 57, and to install an LED behind the lens light guide plate piece 56 of the conventional advertising panel. Uniform brightness and brightness can be achieved even with less LED (4) lighting than the configuration

또한 렌즈도광판편(56)을 분리하여 원하는 위치에 임의로 손쉽게 설치 가능하여 그 사용도 매우 편리하고 여러 구조물에 대한 활용성도 매우 높다In addition, the lens light guide plate 56 is separated and can be easily installed at a desired position, which is very convenient to use and has high utility for various structures.

이와 같이 본 발명은 비록 도광판의 면 가공의 구조적인 작은 변경으로 볼 수도 있으나, 그 파생 효과는 매우 지대하므로 본 발명은 매우 진보적이고 혁신적인 비용절감 및 생산성 향상 효과를 기대할 수 있다As described above, although the present invention may be regarded as a structural small change in the surface processing of the light guide plate, the derivative effect thereof is very large, and thus the present invention may expect very advanced and innovative cost reduction and productivity improvement effects.

2 shows a lenticular light guide plate according to the present invention;
Figure 3 is another embodiment of the present application

이하, 본 발명을 첨부 도면에 의거 상술한다Hereinafter, the present invention will be described in detail with reference to the accompanying drawings

도시한 바와 같이 기판(5) 위에는 엘이디(4)가 장착되고 그 위에는 렌즈도광판(1)이 설치된다. 엘이디(4)가 설치되는 위치에 대응하는 홈이 렌즈도광판(1) 하부에 형성된다As shown in the drawing, the LED 4 is mounted on the substrate 5, and the lens light guide plate 1 is mounted thereon. Grooves corresponding to the positions where the LEDs 4 are installed are formed in the lower part of the lens LGP 1.

본 발명은, 렌즈도광판(1)의 홈(3)에 대응하는 상면 위치에 수평면부(30)를 형성하였다. 그리고 그 좌우로는 약간 볼록하게 라운드진 형상의 구조가 나오도록 하였다In the present invention, the horizontal surface portion 30 is formed at an image position corresponding to the groove 3 of the lens light guide plate 1. On the left and right sides, a slightly convex rounded structure emerged.

상기 구조로 만들기 위하여는 상부에서 엔드밀(33)를 사용하여 성형하는데, 엔드밀(33)은 렌즈도광판(1)의 상부 홈 형상과 동일한 형상으로 이루어진다In order to make the above structure, the upper part is formed by using the end mill 33. The end mill 33 is formed in the same shape as the upper groove shape of the lens LGP 1.

엔드밀(33)은 다이아몬드 재질 또는 초경 등의 재질을 사용할 수 있다. 바람직하기로는 다이아몬드 재질로 사용하는 것이 더욱 장기간 사용 가능하므로 바람직하다. The end mill 33 may use a material such as diamond or carbide. Preferably, it is preferable to use a diamond material because it can be used for a longer period.

엔드밀(33)의 하단부는 수평면을 가공할 수 있는 수평가공부(34)를 형성한다. 이렇게 만드는 이유는 만약 엔드밀(33) 하단부의 가공부를 뾰죽한 형상으로 만들면 렌즈도광판(1)이 절단되거나 통공으로 관통되어 버리기 쉽기 때문이다The lower end of the end mill 33 forms a horizontal processing portion 34 capable of processing a horizontal plane. The reason for this is that if the processing part of the lower end of the end mill 33 is pointed, the lens light guide plate 1 is easily cut or penetrated through the hole.

엔드밀(33)의 수평가공부(34) 주변 측부로는 측가공날(38)을 형성한다The side peripheral edge of the horizontal mill 34 of the end mill 33 forms a side mill 38.

엔드밀(33)의 측가공날(38)은 도 2 와 같은 단면으로 보면 오목한 구조로 이루어진다. 그리하여, 수평면부(30) 좌우로는 볼록한 볼록부(35)를 형성하는데 이는 렌즈도광판(1)의 홈(3)과 수평면부(30) 형성으로 인해 좁아진 그 주변이 취약해지기 쉬우므로 약간 볼록한 형상으로 두께를 갖도록 하는 것이 강도면에서 바람직하기 때문이다. The side machining blade 38 of the end mill 33 has a concave structure when viewed in the cross section as shown in FIG. 2. Thus, the convex portions 35 are formed to the left and right of the horizontal plane portion 30, which are slightly convex because the periphery narrowed by the formation of the groove 3 and the horizontal plane portion 30 of the lens light guide plate 1 is easily vulnerable. It is because it is preferable to have thickness in shape in terms of strength.

또 다른 이유는 볼록 렌즈 효과를 가져와 렌즈와 같은 빛의 분산 효과를 주기 때문에 휘도를 향상시킬 수 있기 때문이다Another reason is that the brightness can be improved by bringing the convex lens effect and the light dispersion effect like the lens.

또한 렌즈도광판(1)의 하면에 형성되는 홈(3)도 동일한 방법으로 엔드밀(33)에 의한 가공으로 만들어 낸다In addition, the grooves 3 formed on the lower surface of the lens light guide plate 1 are also made by processing by the end mill 33 in the same manner.

상기 렌즈도광판(1)의 하면에 형성되는 홈(3)의 위치 중앙에, 원추형으로 이루어지는 원추홈면(50)을 형성하고, 그 외주는 단면상 단턱이 진 단턱부(51)를 형하도록 하기 위해, 상기 하면에 형성되는 홈(3)은 엔드밀(33)로 가공하되, 엔드밀(33)은 원추홈면(50)과 단턱부(51)의 형상으로 가공할 수 있는 상응되는 형상을 갖도록 한다In order to form a conical groove surface 50 formed in a conical shape in the center of the position of the groove 3 formed on the lower surface of the lens light guide plate 1, the outer periphery of the stepped end to form a stepped step 51, The groove 3 formed in the lower surface is processed into an end mill 33, the end mill 33 is to have a corresponding shape that can be processed into the shape of the conical groove surface 50 and the stepped portion (51).

상기와 같이 렌즈도광판(1)에 대하여 엔드밀(33)에 의한 직접 가공 성형을 행하면 렌즈도광판(1)의 상부면의 홈 형성이 한번의 가공으로 이루어지므로 그 가공이 매우 용이하고 생산 속도를 크게 높일 수 있다As described above, when the direct processing molding is performed on the lens light guide plate 1 by the end mill 33, the grooves of the upper surface of the lens light guide plate 1 are formed in one process, so the processing is very easy and the production speed is greatly increased. Can increase

따라서 종래와 같이 사출 성형을 위한 고가의 사출 금형 설비가 불필요하고, 사출 성형 후 2 차적인 오목홈의 면가공이 불필요하다Therefore, expensive injection mold equipment for injection molding is unnecessary as in the prior art, and secondary processing of concave grooves after injection molding is unnecessary.

도 3 은 본 발명의 다른 실시 예이다3 is another embodiment of the present invention.

도시한 바와 같이, 본 발명은 렌즈도광판(1)에 홈(3)을 가공하여 홈(3)이 형성된 각각의 렌즈 형상을 낱개로 분리 가능하도록 하였다As shown, according to the present invention, the groove 3 is processed in the lens light guide plate 1 so that each lens shape in which the groove 3 is formed can be separately separated.

이 경우, 렌즈도광판(1)에 쉽게 낱개로 잘라낼 수 있도록 절취부(55)를 미리 형성하여 둘 수도 있다. 그러면 그 분리한 렌즈도광판편(56)을 이용하여 광고 조명용 판넬(57)의 외형상에 맞추어 판넬(57) 후방에 부착하거나 설치하고 렌즈도광판편(56) 후방에 엘이디를 설치하면 된다. 이렇게 구성하면, 종래의 광고 판넬의 구성보다 엘이디(4) 조명을 적게 사용하고도 균일한 휘도와 밝기를 줄 수 있다In this case, the cutout 55 may be formed in advance so that the lens light guide plate 1 can be easily cut out individually. Then, the separated lens light guide plate piece 56 may be used to be attached or installed at the rear of the panel 57 according to the outer shape of the advertising lighting panel 57, and an LED may be installed behind the lens light guide plate piece 56. This configuration can provide uniform brightness and brightness even when using less LED 4 lighting than the conventional advertising panel configuration.

또한 렌즈도광판편(56)을 분리하여 원하는 위치에 임의로 손쉽게 설치 가능하여 그 사용도 매우 편리하고 여러 구조물에 대한 활용성도 매우 높다
In addition, the lens light guide plate 56 is separated and can be easily installed at a desired position.

이와 같이 본 발명은 비록 도광판의 면 가공의 구조적인 작은 변경으로 볼 수도 있으나, 그 파생 효과는 매우 지대하므로 본 발명은 매우 진보적이고 혁신적인 비용절감 및 생산성 향상 효과를 기대할 수 있다.As described above, although the present invention may be regarded as a structural small change in the surface processing of the light guide plate, since the derivative effect thereof is very large, the present invention can be expected to be very advanced and innovative cost reduction and productivity improvement effect.
