Description

광각 발광소자를 이용한 광고 표시장치 {Apparatus for advertisement display using P4 LED}Ad display using wide-angle light emitting device {Apparatus for advertisement display using P4 LED}

본 발명은 광고 표시판에 관한 것으로서, 보다 상세하게는 고휘도 면발광을 위한 발광소자(Light Emitting Diode : 이하 "LED"라 약칭함.)를 이용하여 광고판을 제작하므로 소수의 LED로 고휘도의 광고 표시판을 제작하도록 하는 광각 LED를 이용한 광고 표시장치에 관한 것이다.The present invention relates to an advertisement display panel, and more particularly, to produce an advertisement panel using a light emitting diode (Light Emitting Diode (hereinafter, abbreviated as "LED")) for high brightness surface light emission. It relates to an advertising display device using a wide-angle LED to produce.

일반적으로 실내 또는 실외의 광고물이나 간판 등은 야간에 쉽게 인식될 수 있도록 네온가스를 이용한 네온사인이나 LED 등을 이용한 발광구조로 제작하거나, 또한, 실사출력한 그래픽 뒷면에 형광등을 넣어 광고하는 파나플렉스 형태가 사용된다.In general, indoor or outdoor advertisements or signs are manufactured with a light emitting structure using neon signs or LEDs using neon gas, or put a fluorescent light on the back of the graphic printed out in order to be easily recognized at night. Flex form is used.

여기서, 네온사인을 이용한 광고물의 경우에는 휘도가 높아 육안식별이 용이하나, 네온관이 노출되어 있으므로 파손되기 쉬우며, 물청소가 어려울 뿐만아니라, 고전압을 이용하기 때문에 전력소비가 많고 고온이 열이 발생하여 비효율적이다.Here, in the case of advertisements using neon signs, the brightness is high, so it is easy to visually identify, but the neon tube is exposed, so it is easy to be damaged, and it is difficult to clean the water, and because of the high voltage, power consumption is high and heat is generated. It is inefficient.

이러한 비효율적인 문제 때문에 일반적으로 LED를 이용하여 광고판을 사용하는 경우가 많으며, 이와 같은 LED를 이용한 광고판은 대한민국 특허 출원 "제 10-2000-49978 호"(실내/외 광고물 제조방법)에 개시되어 있으며, 발광다이오드를 이용한 면발광 광고표시판으로 대한민국 실용신안 등록 "제 20-178982 호"(합성수지와 발광 다이오드를 이용한 빛의 발산구조체)에 개시되어 있다.Due to this inefficient problem, a billboard is usually used by using LED, and the billboard using such LED is disclosed in Korean Patent Application No. 10-2000-49978 (indoor / outdoor advertising method). It is disclosed in Korean Utility Model Registration No. 20-178982 (light emitting structure using synthetic resin and light emitting diode) as a surface light emitting display panel using a light emitting diode.

도 1a, 1b는 종래 기술에 따른 일반적인 LED를 이용한 빛의 발산 구조체의 단면 사시도로서, 도 1a에 도시된 빛의 발산구조체(5)는 LED(10), 반사층(20), 수지충전물(30), 투광창(40), 외곽틀(50)을 구비한다. 외곽틀(50)의 내부에 반사층(20), LED(10), 수지충전물(30) 등을 순서대로 설치하고, 맨 위에 투광층(40)을 덮어서 제작한다. 투광창(40)의 바깥면은 발광면(51)을 이룬다.1A and 1B are cross-sectional perspective views of a light emitting structure using a conventional LED according to the prior art, wherein the light emitting structure 5 shown in FIG. 1A includes an LED 10, a reflective layer 20, and a resin filler 30. And a floodlight window 40 and an outer frame 50. The reflective layer 20, the LED 10, the resin filler 30, and the like are sequentially installed in the outer frame 50, and the transparent layer 40 is covered on the top. The outer surface of the light transmission window 40 forms a light emitting surface 51.

도 1b는 칩(chip)형 LED를 이용한 빛의 발산구조체의 단면 사시도로로서, 칩형 LED(60), 반사층(20), 수지충전물(30), 외곽특(50)을 구비한다. 외곽틀(50)의 내부에 반사층(20), 칩형 발광소자(10), 수지충전물(30) 등을 순서대로 설치하여구성하되, 수지충전물(30)의 상층부는 형광물질 혹은 인광물질을 혼합하여 구성한 형광층(35)가 형성된다. 수지충전물(30)의 윗면은 외곽틀(50)의 바깥부분 중 빛을 발산하는 발광면(51)을 이룬다.FIG. 1B is a cross-sectional perspective view of a light emitting structure using a chip type LED, and includes a chip type LED 60, a reflective layer 20, a resin filler 30, and an outer shell 50. The reflective layer 20, the chip-shaped light emitting device 10, the resin filler 30, etc. are installed in order in the outer frame 50, and the upper layer portion of the resin filler 30 is mixed with fluorescent materials or phosphorescent materials. The configured fluorescent layer 35 is formed. The upper surface of the resin filler 30 forms a light emitting surface 51 that emits light among the outer portions of the outer frame 50.

여기서, 칩형 LED(60)는 일반적인 LED(10)와는 달리 연결단자(11), 발광배선(12)등이 별도로 연결되지 않고 편편한 PCB(Printed Circuit Board)(62) 위의 LED(61)가 납땜등의 방법으로 부착된 형태를 이룬다.Here, the chip type LED 60, unlike the general LED 10, the connection terminal 11, the light emitting wiring 12, etc. are not connected separately, the LED 61 on the flat PCB (Printed Circuit Board) (62) is soldered To form the attached form by such a method.

이러한 칩형 LED(60)를 채용하면 빛의 발산구조체(6) 두께를 줄일 수 있다는 장점이 있다. 반사층(20)과 수지충전물(30)은 도 1의 구조와 동일하며, 형광층(35)은 LED(61)에서 나오는 빛을 다양한 색깔로 발산함으로써, 발광면(51)의 발광효과를 증진시킨다. 발광면(51)을 제외한 외곽틀(50)의 구조는 도 1의 구조와 동일하다.Employing such a chip-shaped LED (60) has the advantage of reducing the thickness of the light emitting structure (6). The reflective layer 20 and the resin filler 30 are the same as those of FIG. 1, and the fluorescent layer 35 emits light emitted from the LED 61 in various colors, thereby enhancing the light emitting effect of the light emitting surface 51. . The structure of the outer frame 50 except for the light emitting surface 51 is the same as the structure of FIG.

이와 같은 종래기술에 따른 빛의 발산구조체는 외곽틀 안의 바닥면, 양측면에 소정의 우레탄 페인트를 이용하여 반사판을 만들어 표면에 보다 밝은 빛을 내도록하고, 양측면과 표면에 투명에폭시를 충진시킴으로 빛을 산란시켜 면발광의 효과를 얻게 된다.Such a light diverging structure according to the prior art uses a predetermined urethane paint on the bottom surface and both sides of the outer frame to make a reflection plate to give a brighter light to the surface, filling the transparent epoxy on both sides and the surface to scatter the light The effect of surface light emission is obtained.

그러나, 이와 같은 종래기술에 따른 빛의 발산구조체는 외곽틀 안에 반사판과 양쪽 벽면 등에 투명에폭시를 충진시켜야 하는 복잡한 과정을 거쳐야되는 문제점이 있었다. 또한, 종래 기술에 의하여 제작된 광고표시판의 경우에는 사용되는 LED 또는 칩형 LED의 특성상 발광시 광각이 좁아 에폭시로 산란되었다 하더라도, LED 발광 초점이 육안으로 인식되어, 다수개의 LED 또는 칩형 LED를 사용하여 광고표시판을 제작할 경우 표면의 밝기가 고르지 않으므로, 장시간 바라볼 경우 눈에 피로감을 주는 문제점이 있었다. 또한, LED 또는 칩형 LED의 경우 발열이 많은데다가 에폭시로 밀폐시킴으로 방열효과가 더 떨어져 장시간 사용시 수명이 떨어지는 문제점이 있었다.However, the light diverging structure according to the prior art has a problem of having to go through the complicated process of filling the transparent epoxy on the reflecting plate and both walls in the outer frame. In addition, in the case of the advertisement display panel manufactured according to the prior art, even if the wide angle of light emission is narrow due to the nature of the LED or chip-type LED used, the focus of LED light emission is visually recognized, and a plurality of LEDs or chip type LEDs are used. Since the brightness of the surface is uneven when manufacturing the billboard, there was a problem of eye fatigue when viewed for a long time. In addition, in the case of LED or chip type LED, there is a problem that the heat dissipation effect is further lowered by using a lot of heat and the heat sealing effect is further sealed by epoxy.

본 발명은 상기한 종래기술의 제반 문제점을 해결하기 위한 것으로, 그 목적은 고휘도 면발광을 위한 4개의 핀을 갖는 광각 LED(이하 "P4 LED"라 약칭함)를 광원으로 이용하여 광고 표시판을 제작하므로, 소수의 LED로도 고휘도의 광고 표시판을 제작하도록 하는 광각 LED를 이용한 광고 표시장치에 관한 것이다.The present invention is to solve the above problems of the prior art, the purpose is to produce a display board using a wide-angle LED having a four-pin (hereinafter abbreviated as "P4 LED") as a light source for high brightness surface light emission Therefore, the present invention relates to an advertisement display device using a wide-angle LED to produce a high brightness advertisement display panel even with a small number of LEDs.

이와 같이 이루어진 본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention made as described above will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일 실시 예에 따른 광각 LED를 이용한 광고 표시장치의 구조도로서, 광고 표시판을 고정하는 프레임(101)과, 프레임 상부에 소정의 광고 문양 또는 문자 형태의 외곽틀(110)과, 외곽틀 내부에 하단에 부착된 인쇄회로기판(111)과, 인쇄회로기판(111)의 해당 위치에 접속된 P4 LED(112)와, P4 LED(112) 주변과 외곽틀 내부에 충진된 투명 에폭시(114)와, 외곽틀(110)을 밀폐시키도록 투명에폭시(114) 표면에 부착된 색상 에폭시(113)으로 형성된다.2 is a structural diagram of an advertisement display device using a wide-angle LED according to an embodiment of the present invention, a frame 101 for fixing an advertisement display plate, an outer frame 110 having a predetermined advertisement pattern or character shape on the frame and The printed circuit board 111 attached to the bottom inside the outer frame, the P4 LED 112 connected to the corresponding position of the printed circuit board 111, and the transparent filled around the P4 LED 112 and the inside of the outer frame Epoxy 114 and a color epoxy 113 attached to the surface of the transparent epoxy 114 to seal the outer frame 110 is formed.

이와 같이 형성된 본 발명의 작용을 첨부된 도면을 참조하여 보다 상세히 설명하면 다음과 같다.Referring to the attached operation of the present invention formed as described above in more detail as follows.

먼저, 본 발명은 광각 발광소자인 P4 LED를 사용하여 광고 표시판을 제작하므로 광고 표시판 표면에 고르게 분산시켜 면발광 효과를 극대화 시키도록 한다.First, since the present invention manufactures an advertisement display panel using a P4 LED, which is a wide-angle light emitting device, the surface of the advertisement display panel is evenly distributed to maximize the surface light emitting effect.

도 2는 본 발명의 실시예에 따른 광각 LED를 이용한 광고표시장치의 단면 형상도로서, 프레임(101) 위에 광고 표시장치를 고정하게 된다.2 is a cross-sectional view of the advertisement display device using the wide-angle LED according to an embodiment of the present invention, and the advertisement display device is fixed on the frame 101.

광고표시장치는 도 4에 도시된 바와 같이 다양한 도형 또는 문자 모양의 상부가 개방된 외곽틀(110)을 형성한다.As shown in FIG. 4, the advertisement display device forms an outer frame 110 in which upper portions of various figures or letters are opened.

외곽틀(110)의 바닥면에 P4 LED(112)가 접속된 PCB(111)를 설치한다.The PCB 111 to which the P4 LED 112 is connected is installed on the bottom surface of the outer frame 110.

이때, 외곽틀(110) 내부에 흰색 우레탄 페인트 등을 이용하여 반사판을 만들지 않아도 되며, 틀 높이에서 2∼3㎜ 정도를 남겨놓은 다음 투명 에폭시(114)를 충진시킨다. 그 다음 필요에 따라서 염료를 섞은 색상 에폭시(113)를 충진시켜 표면에 직접 빛을 비춰 빛을 손실없이 최대로 활용하여 면발광 방식을 이루게 하는 것이다.At this time, it is not necessary to make a reflector plate using a white urethane paint or the like inside the outer frame 110, and leaves about 2-3 mm at the height of the frame and then fills the transparent epoxy 114. Then, if necessary, by filling the color epoxy 113 mixed with dye to shine directly on the surface to utilize the maximum light without loss to achieve a surface emitting method.

여기서, 외곽틀(110)의 내부에 충진하는 투명 에폭시(114)는 필요에 따라 충진하지 않고, 외곽틀(110)의 상부에 색상 에폭시(113)만을 충진하여 외곽틀(110)을밀폐시키도록 한다.Here, the transparent epoxy 114 filling the inside of the outer frame 110 is not filled as necessary, and only the color epoxy 113 is filled in the upper portion of the outer frame 110 to seal the outer frame 110. do.

PCB(111)에 접속되어 발광하는 P4 LED(112)는 일반적인 LED나 칩 LED와는 달리 4개의 접속핀을 구비하고 있어 전류가 흐를 때 생기는 열을 외부로 빨리 방출시키므로, 방열효과가 매우 우수하며, 그에 따라 다른 LED에 비교하여 수명이 매우 길다. 뿐만 아니라, 빛의 밝기가 일반적인 LED에 비교하여 매우 밝으며, 광각이 100°이상으로 동일 면적을 면발광 방식으로 제작할 때 칩 LED보다 훨씬 적은 수량으로 제작할 수 있으므로, 고휘도임에도 불구하고 초점이 생기지 않아 빛의 손실없이 표면을 고르게 분산시킬 수 있게 된다.Unlike the general LED or chip LED, the P4 LED 112 connected to the PCB 111 has four connection pins, and thus quickly radiates heat generated when current flows to the outside, thereby providing excellent heat dissipation effect. As a result, the lifetime is very long compared to other LEDs. In addition, the brightness of the light is much brighter than that of general LEDs, and when the wide area is more than 100 °, the same area can be manufactured in a much smaller quantity than the chip LEDs. The surface can be evenly distributed without losing light.

도 3은 광고 표시장치에서 외곽틀의 바닥면으로 빛을 조사하도록 하여 문양 또는 문자등의 광고 표시장치에 후광의 효과를 주도록 한 것이다.3 is to illuminate the bottom surface of the outer frame in the advertising display device to give the effect of a halo on the advertising display device such as a pattern or text.

이를 위하여 프레임(101)의 상부와 일정간격을 두고 광고표시장치를 고정시키게 된다. 이때 외곽틀(110)은 개방된 그 상부가 프레임(101)측으로 향하도록 하고, 그 바닥면에 PCB(111)를 고정시키고, P4 LED(112)의 조사방향이 외곽틀(110)의 상부를 향하도록 PCB(111)의 해당 위치에 4개의 접속핀을 고정시킨다.To this end, the advertisement display device is fixed at a predetermined interval with the upper portion of the frame 101. At this time, the outer frame 110 is open to the upper side toward the frame 101 side, the PCB 111 is fixed to the bottom surface, the irradiation direction of the P4 LED 112 to the upper portion of the outer frame 110 Four connection pins are fixed to the corresponding positions of the PCB 111 so that they face each other.

외곽틀(110)내부는 필요한 경우 투명 에폭시(114)로 충진하거나, 투명 에폭시(114) 충진없이 개방된 외곽틀(110)의 상부를 색상 에폭시로 충진시켜 밀폐하도록 한다.The outer frame 110 may be filled with transparent epoxy 114 if necessary, or filled with a color epoxy to fill the upper portion of the open outer frame 110 without filling the transparent epoxy 114.

이와 같이 완성된 후광용 광고 표시장치는 광고하고자 하는 문자 또는 문양에 후광 효과를 주어 심미감을 더 할 수 있게 된다.The completed advertising display device for the halo can add aesthetic effect to the character or pattern to be advertised.

이상에서 본 발명에 따른 바람직한 실시예에 대해 설명하였으나, 외곽틀의형태를 단면발광, 3면 입체 발광, 후광발광 등 다양한 형상으로 변형이 가능하며, 본 기술분야에서 통상의 지식을 가진자라면 본 발명의 특허청구범위를 벗어남이 없이 다양한 변형예 및 수정예를 실시할 수 있을 것으로 이해된다.Although a preferred embodiment according to the present invention has been described above, the shape of the outer frame can be modified into various shapes such as cross-sectional light emission, three-sided three-dimensional light emission, and back light emission, and those skilled in the art will appreciate It is understood that various modifications and variations can be made without departing from the scope of the claims.

이상에서 설명한 바와 같이, 본 발명에 따른 광각 LED를 이용한 광고표시장치는 광각의 P4 LED를 사용하므로, 외곽틀 내부에 투명 에폭시로 광원을 산란시키지 않아도 광원이 광고 표면에 고르게 분산되어 눈의 피로를 줄일 수 있고, 심미감을 더 할 수 있으며, 광각으로 조사므로 일반적인 LED를 사용할 때 보다 적은 수의 P4 LED만을 사용해도 보다 효과적으로 면발광시킬 수 있는 효과가 있다. 또한, 내부에 투명 에폭시를 충진시킬 필요가 없고, 효과적인 면발광을 위하여 별도의 반사판이 필요없으므로 제조공정이 간단할 뿐만 아니라, 광고표시장치의 전체 무게와 제작비용을 줄일 수 있는 효과가 있다.As described above, since the advertisement display device using the wide-angle LED according to the present invention uses a wide-angle P4 LED, the light source is evenly distributed on the advertisement surface without scattering the light source with transparent epoxy inside the outer frame, thereby reducing eye fatigue. Since it can be reduced, added aesthetics, and wide-angle illumination, it is possible to more effectively surface-luminesce using only a small number of P4 LEDs when using ordinary LEDs. In addition, there is no need to fill the transparent epoxy inside, and there is no need for a separate reflector plate for effective surface emission, so that the manufacturing process is simple, and the overall weight and manufacturing cost of the advertisement display device can be reduced.
