일반적으로 매트는 바닥에 깔려서 사람들이 발로 밟고 지나가면서 발에 묻은 물기 또는 흙 등의 이물질을 제거하는 역할을 한다. 최근에는 이러한 기능 외에 매트 자체가 발광기능을 가지고 있어서, 사람들의 눈에 잘 띄이며, 이로 인하여 광고판 역할까지 할 수 있는 매트가 등장하였다.In general, the mat is laid on the floor to remove the foreign substances such as water or dirt on the feet as people walk on the foot. Recently, in addition to these functions, the mat itself has a light emitting function, so that people can easily stand out, and thus a mat that can serve as a billboard has emerged.
그러나 이러한 종래의 발광매트는 대부분 매트의 세척을 어떻게 할지에 중점을 두었을 뿐, 발광체에서 발산하는 빛을 이용하여 그 발광매트가 전달하고자 하는 내용을 발광매트에 인접한 사람들에게 어떻게 효과적으로 전달할지에 대한 시도는 없었다.However, these conventional light emitting mats mostly focused on how to clean the mat, and how to effectively deliver the contents that the light emitting mat wants to deliver to the people adjacent to the light emitting mat by using light emitted from the light emitting body. There was no attempt.
일반적으로 발광매트는 야간이나 어두운 실내에서 사용하는 경우가 많은데, 종래의 발광매트, 특히 전방으로 직진하려는 특성이 강한 LED에서 방사되는 빛을 이용한 발광매트는 LED의 특성으로 인하여 매트의 바로 위에서 발광매트를 보면 LED가 눈을 심하게 자극하여 눈이 부시는 현상이 발생하고, 발광매트로부터 어느 정도의 거리에 위치하는 사람의 눈에는 빛이 거의 발산하지 않는 LED의 측면을 보게 되므로 LED가 나타내려는 내용을 제대로 알 수 없다는 단점이 있었다. In general, the light emitting mat is often used at night or in a dark room. Conventional light emitting mats, especially light emitting mats using light emitted from LEDs having a strong characteristic of going straight ahead, have a light emitting mat directly above the mat due to the characteristics of the LED. If you look at the LED, the eyes will be irritated and the eyes will be dazzled and the eyes of people located at a certain distance from the light emitting mat will see the side of the LED that emits little light. There was a disadvantage of not knowing properly.

본 발명에 의한 시인성이 향상된 발광매트는 매트에 인쇄된 내용을 강조하기 위한 발광수단으로서의 LED 어셈블리가 부착되어 있으므로, 다른 여타의 매트들에 비하여 사람들의 시선을 확 끌어 당길 수 있다. 특히 야간의 경우에는 다른 모든 매트들이 단순히 신발에 묻어 있는 이물질을 제거하는 정도의 역할밖에 수행하지 못하지만, 본 발명에 의한 발광매트는 다양한 색깔과 형태의 발광체를 이용하여 사람들의 시선을 끌 수 있을 뿐 아니라 환상적인 빛의 조화에 의해 사람들의 뇌리에 오래 기억될 수 있다.The light emitting mat with improved visibility according to the present invention is attached to the LED assembly as a light emitting means for emphasizing the content printed on the mat, it can attract the eyes of people compared to other mats. Especially at night, all other mats play a role of simply removing foreign matters on the shoes, but the light emitting mat according to the present invention can attract people's eyes by using light emitting bodies of various colors and shapes. But it can be remembered for a long time by the fantastic harmony of light.
나아가 본 발명에 의한 발광매트는 박막투광부와 후막투광부를 갖춘 LED 어셈블리를 사용함으로서 원거리/근거리 및 정면/측면에서의 시인성이 향상된다. 특히 LED의 정면, 매트의 상부에서의 눈부심 현상이 완화되고, LED의 측면에서도 LED의 빛을 수월하게 인식할 수 있다.Furthermore, the light emitting mat according to the present invention improves visibility at long distance / near distance and front / side by using an LED assembly having a thin film light emitting part and a thick film light transmitting part. In particular, glare from the front of the LED and the top of the mat is alleviated, and the light of the LED can be easily recognized from the side of the LED.
또한 LED 빛의 색과 투광부의 색을 같거나 다르게 하거나, 또는 박막투광부와 후막투광부의 두께를 달리하여 하나의 LED 어셈블리로도 2개이상의 다양한 빛을 표현할 수 있으므로, 본 발명에 의한 발광매트는 환상적인 빛을 발산하여 보는 사람의 뇌리에 깊은 인상을 남길 수 있으므로 단순한 매트가 아닌 제2의 광고판으로서의 역할도 수행한다.In addition, since the color of the LED light and the color of the light-transmitting part may be the same or different, or the thicknesses of the thin-film light-emitting part and the thick-film light-emitting part may represent two or more various lights even with one LED assembly, the light emitting mat according to the present invention Because it can make a deep impression on the viewer's mind by emitting fantastic light, it also serves as a second billboard, not just a matte.
또한 전방으로만 비추던 종래의 LED와 달리, 본 발명에 사용된 LED는 측면으로도 빛이 조사되어져서, 전체적으로 하나의 LED 어셈블리가 커버하는 면적이 넓게 되고, 이로 인하여 적은 수의 LED를 사용하면서도 다수의 LED를 사용하는 것 과 같은 효과를 얻을 수 있다. 따라서 본 발명에 의한 발광매트에 사용된 LED는 같은 범위를 비추더라도 종래의 LED에 비하여 적은 수의 LED를 사용함에 따라 소모전력이 상대적으로 적고, 따라서 친환경적이지만 효율이 낮은 태양광전기를 사용하기에 적합하고, 또한 밧데리를 사용할 경우에도 장시간에 걸쳐서 밧데리를 사용할 수 있는 장점이 있다. 따라서 설치비 뿐 아니라 유지비가 절감되는 반면에 그 효과는 극대화된다.In addition, unlike the conventional LED that was only shining forward, the LED used in the present invention is also irradiated with light from the side, so that the overall area covered by one LED assembly, thereby using a small number of LEDs The same effect as using multiple LEDs can be obtained. Therefore, the LED used in the light emitting mat according to the present invention has a relatively low power consumption by using a smaller number of LEDs compared to the conventional LEDs even though it reflects the same range, so it is suitable to use an eco-friendly but low-efficiency solar cell. In addition, there is an advantage that the battery can be used for a long time even when using the battery. Therefore, not only installation costs but also maintenance costs are reduced, while the effect is maximized.
또한 매트층과 지지층이 서로 분리될 수 있으므로, 세척을 할 필요가 있는 경우에는 단순히 매트층만 세척을 하면 되므로, 세척이 매우 용이하다. 또한 기존의 발광매트는 LED에 캡이 설치되었어도 사람이 밟았을 때 외부의 충격에 따라서 LED가 흔들리면서 LED의 납땜부위가 파손되어 불이 들어오지 않는 불량이 있었으나 본 발명에서는 이러한 문제를 해결하기 위하여 LED의 측면에 측벽을 설치하여 LED를 외부의 충격으로부터 안전하게 보호할 수 있도록 했다. 또한 글자나 문양의 크기에 따라서 전선의 길이를 조정이 가능하도록 하여 작업시 전선의 휘어짐으로 인한 LED접촉부위의 불량을 방지할 수 있도록 한다.In addition, since the mat layer and the support layer can be separated from each other, it is very easy to wash because only the mat layer needs to be washed when it is necessary to wash. In addition, the conventional light emitting mat, even if the cap is installed on the LED, when the person stepped on the LED shakes according to the external impact when the soldering part of the LED was broken, there was a defect that does not light, but in the present invention to solve this problem Side walls are provided on the sides to protect the LEDs from external shocks. In addition, it is possible to adjust the length of the wire according to the size of the letter or pattern to prevent the defective LED contact portion due to the bending of the wire during work.

Position and serves to fix the fibers in the fibrous layer. The fiber fixing layer is preferably made of a rubber material. In particular, it is preferable to use raw rubber among rubbers.
지지층(3000)은 매트층(2000)의 하부에 위치하며, 지지층(3000)에는 LED 어셈블리(100)가 부착된다. 지지층(3000)의 형태에 대해서는 특별한 제한은 없으나, 바람직하게는 상판(3100)과 하판(3200)을 포함한다. 상판(3100)은 매트층(2000)의 하부와 접하며, 상기 매트발광공(2100)에 대응하는 위치에 상판발광공(3110)이 형성될 수도 있다. 상판발광공(3110)은 후술하는 투광부가 관통할 수도 있고, 전선(110)이 관통할 수도 있으며, 그 크기는 관통하는 것이 무엇이냐에 따라 결정된다.The support layer 3000 is positioned below the mat layer 2000, and the LED assembly 100 is attached to the support layer 3000. The shape of the support layer 3000 is not particularly limited, but preferably includes an upper plate 3100 and a lower plate 3200. The upper plate 3100 may be in contact with the lower portion of the mat layer 2000, and the upper plate emitting hole 3110 may be formed at a position corresponding to the mat emitting hole 2100.

도 2는 본 발명에 사용된 LED 어셈블리 단면도이다. 도 2에서 보는 바와 같이, 본 발명에 의한 LED 어셈블리(100)는 LED(1)와 투광부(10)를 포함하며, 경우에 따라서는 고정부(30)도 포함할 수 있다. 이하 각 부분에 대하여 설명한다. 2 is a cross-sectional view of the LED assembly used in the present invention. As shown in FIG. 2, the LED assembly 100 according to the present invention includes an LED 1 and a light transmitting unit 10, and in some cases, may also include a fixing unit 30. Each part is demonstrated below.
본 발명에서 사용되는 LED는 그 형태에 대해서는 특별한 제한은 없다. 예를 들어 LED 발광 부분이 도 2와 같이 긴 경우 뿐 아니라, 도 3과 같이 LED 발광 부분이 짧은 경우도 포함한다. 여기서 도 3과 같이 LED 발광부분이 짧은 경우에는 도 2와 비교하여 LED 측면의 밝기가 더욱 강조될 수 있다. 나아가 도 3과 같이 LED 발광 부분이 짧은 경우에는 투광부의 형상이 LED 발광부의 형상에 따라서 변형될 수도 있다. 그 외에도 발광 부분이 짧지만 넓은 형태의 LED 및 둥근형태의 LED도 본 발명에 적용될 수 있음은 당연하다. LED used in the present invention is not particularly limited in its form. For example, the LED light emitting part is not only long as shown in FIG. 2 but also the case where the LED light emitting part is short as shown in FIG. 3. Here, when the LED emitting portion is short as shown in FIG. 3, the brightness of the LED side surface may be further emphasized as compared with FIG. 2. Furthermore, when the LED light emitting part is short as shown in FIG. 3, the shape of the light transmitting part may be modified according to the shape of the LED light emitting part. In addition, although the light emitting portion is short, it is natural that a wide LED and a round LED may also be applied to the present invention.
본 발명에 사용되는 LED는 적어도 하나이상 설치된다. 여기서 LED의 갯수에 대해서는 특별한 제한은 없다. 다수의 LED가 설치되어지는 경우에는 서로 다른 색의 LED가 설치될 수 있고, 나아가 개개의 LED가 설치되어지는 각도를 달리하여 설치할 수도 있다. 이는 LED에서 방출되는 빛의 직진성을 고려하여 다양한 각도에서의 시인성을 향상시키기 위함이다. At least one LED is used in the present invention. There is no particular limitation on the number of LEDs here. When a plurality of LEDs are installed, LEDs of different colors may be installed, or may be installed with different angles at which individual LEDs are installed. This is to improve visibility at various angles in consideration of the linearity of light emitted from the LED.
투광부(10)는 LED(1)의 발광부분을 둘러싸고 LED(1)의 빛을 외부로 투과시키며 저면이 평평한 형태를 이루게 된다. 투광부(10)는 빛이 난사되는 것을 방지하고 조사 범위를 형상의 크기로 지정하여 빛의 집중도를 높이고 형상의 모양에 따라 다양한 표현이 가능하고 하나의 LED 어셈블리에 여러 개의 색, 모양 및 밝기가 표현될 수 있도록 한다. 또한 투광부(10)는 LED(1)의 발광부분을 둘러싸고 있으므로, LED(1)에 가해지는 외부충격으로부터 LED(1)를 보호하는 역할을 수행한다. LED(1)에서 방출된 빛은 투광부(10)를 거쳐서 외부로 방출되는데, 투광부(10)를 거치면서 빛은 반사, 회절등을 하게 된다. 본 발명에서의 투광부(10)의 형상에 대해서는 특별한 제한은 없지만, 시인성을 더욱 향상시키기 위하여 적어도 하나 이상의 박막투광부(12)와 적어도 하나 이상의 후막투광부(14)를 포함하는 것이 바람직하다.The light transmitting part 10 surrounds the light emitting part of the LED 1, transmits the light of the LED 1 to the outside, and has a flat bottom surface. The light-emitting unit 10 prevents light from being scattered and increases the concentration of light by designating the irradiation range as the size of the shape, and various expressions can be made according to the shape of the shape. To be expressed. In addition, since the light-transmitting portion 10 surrounds the light emitting portion of the LED 1, it serves to protect the LED 1 from the external impact applied to the LED (1). The light emitted from the LED 1 is emitted to the outside through the light-transmitting portion 10, the light is reflected, diffraction, etc. while passing through the light-transmitting portion 10. The shape of the light transmitting part 10 in the present invention is not particularly limited, but in order to further improve visibility, it is preferable to include at least one thin film light emitting part 12 and at least one thick film light transmitting part 14.
박막투광부(12)는 LED(1)의 빛을 원거리까지 도달시키되 LED의 바로 앞인 매트 상부에서의 눈부심 현상을 완화시키기 위하여 투광부의 두께가 얇은 부분이고, 후막투광부(14)는 LED(1)의 빛을 넓게 분산시켜서 LED(1)의 측면에서도 LED(1)의 빛을 쉽게 인식하여 형상을 강조하기 위하여 투광부의 두께가 상기 박막투광부(12)보다 두꺼운 부분이다. 박막투광부(12)에서는 LED(1) 빛이 통과하는 매질의 두께가 얇으므로, 빛은 에너지의 손실이 없이 거의 대부분 통과하게 되고, 따라서 비교적 원거리에 있는 사람들도 박막투광부(12)에서 방출되는 빛을 인식할 수 있게 된다. 그러나 박막투광부(12)에도 얇은 막이 존재하게 되므로 이로 인하여 LED의 정면 바로 앞인 매트 상부에서의 눈부심 현상이 완화된다. 따라서 매트위를 걸어가는 사람의 시야를 방해하지 않는다.The thin-film light-emitting part 12 is a thin portion of the light-transmitting part in order to reach the light of the LED (1) to a long distance, to alleviate the glare phenomenon in the upper part of the mat just in front of the LED, and the thick-film light-emitting part 14 is the LED (1) The thickness of the light transmitting part is thicker than the thin film light emitting part 12 in order to emphasize the shape by easily dispersing the light of the LED and also easily recognize the light of the LED 1 from the side of the LED 1. Since the thickness of the medium through which the LED 1 light passes is thin in the thin film transmitting part 12, the light passes almost without any loss of energy, so that even people at a relatively long distance are emitted from the thin film transmitting part 12. It becomes possible to recognize the light. However, since the thin film is also present in the thin film transmitting portion 12, the glare phenomenon in the upper portion of the mat just in front of the LED is alleviated. Therefore, it does not disturb the vision of the person walking on the mat.
박막투광부(12)의 두께는 설치되어지는 LED의 휘도에 따라서 달라진다. 통상적인 LED의 경우에는 두께가 0.1~10mm가 바람직하다. 0.1mm미만이면 바로 앞에서 눈부심 현상이 있으며, 10mm 초과하면 LED 빛이 박막투광부에 의해 방해를 받아서 멀리까지 도달하기 어렵다.The thickness of the thin film light-transmitting portion 12 depends on the brightness of the LED to be installed. In the case of a conventional LED, the thickness is preferably 0.1 to 10 mm. If it is less than 0.1mm, there is glare in front of it, and if it exceeds 10mm, the LED light is disturbed by the thin-film light emitting part and it is difficult to reach far.
박막투광부(12)는 빛을 원거리까지 도달할 수 있도록 하면서도, 아울러 LED 바로 앞인 매트 상부에서의 눈부심 현상이 완화시켜서 전체적으로 시인성을 향상시킨다. The thin-film light-emitting part 12 allows the light to reach a long distance, and at the same time, the glare phenomenon in the upper part of the mat directly in front of the LED is alleviated to improve the overall visibility.
이러한 박막투광부(12)는 투광부(10) 내부에 구멍을 뚫어서 박막투광부를 주변보다 얇게 하거나, 투광부 외부 표면 중 빛이 강하게 발산되어야 할 부분을 주변보다 얇게 성형하는 방법으로 형성할 수 있다.The thin film light emitting part 12 may be formed by drilling a hole in the light transmitting part 10 to make the thin film light transmitting part thinner than the surroundings, or by forming a portion of the outer surface of the light transmitting part to which light is strongly emitted to be thinner than the surroundings. .
도 2에서는 박막투광부(12)를 측면에서 볼 때 평평한 형태를 도시하였지만, 필요에 따라서는 빛이 확산될 수 있는 볼록한 형태 또는 빛이 모일 수 있는 오목한 형태를 가질 수도 있다.In FIG. 2, the thin film light-emitting part 12 is shown in a flat shape when viewed from the side, but if necessary, it may have a convex shape in which light may be diffused or a concave shape in which light may be collected.
후막투광부(14)는 투광부의 두께가 박막투광부(12)보다 두꺼운 부분으로서, 매질이 두꺼우므로 매질을 통과하는 빛의 일부는 내부에서 반사가 되어 후막투광부(14)의 전체에 걸쳐서 빛이 분산되어 외부로 방출되게 된다. 따라서 후막투광부(14)에서 방출되는 빛은 박막투광부(12)에서 방출되는 빛에 비하면 어두우나, 전체적으로 분산되어서 LED(1)의 발광방향의 정면 뿐 아니라 측면에서도 그 형태를 인식할 수 있게 되어서, 측면에 있는 사람들에게도 홍보하려는 내용을 정확하게 전달할 수 있다.The thick-film transparent portion 14 is a portion where the thickness of the transparent portion is thicker than the thin-film transparent portion 12, and since the medium is thick, a part of the light passing through the medium is reflected inside, so that the light is spread over the entire thick-film transparent portion 14. This is dispersed and released to the outside. Therefore, the light emitted from the thick film transmitting part 14 is darker than the light emitted from the thin film transmitting part 12, but it is dispersed as a whole so that the shape can be recognized from the front as well as the side of the emitting direction of the LED 1. So you can communicate exactly what you want to promote to the people on your side.
결과적으로 박막투광부(12)에서 방출되는 빛은 LED(1) 정면 바로 앞인 매트상부에서의 눈부심 현상을 완화시켜서 매트 위를 걸어가는 사람들의 시야를 방해하지 않으면서도 LED를 외부충격으로부터 효과적으로 보호할 수 있으며, 후막투광부(14)에서 방출되는 빛은 LED(1)의 측면으로도 LED 빛이 방출되어서 LED(1)의 빛의 진행방향의 측면에서도 그 형태를 사람들이 쉽게 인지할 수 있게 하여 시인성 향상에 기여하게 된다. 나아가 박막투광부(12)에서의 빛은 밝으며, 후막투광부(14)에서의 빛은 은은하게 비추어 박막투광부(12)와 후막투광부(14)가 조화를 이루어 시각적으로 매우 탁월한 효과를 나타내며 원거리/근거리 및 정면/측면에서의 시인성이 향상된다.As a result, the light emitted from the thin-film light-emitting part 12 mitigates the glare on the top of the mat directly in front of the LED 1 to effectively protect the LED from external shocks without disturbing the view of people walking on the mat. The light emitted from the thick film transmitting part 14 may emit light from the side of the LED 1 so that people can easily recognize the shape in terms of the traveling direction of the light of the LED 1. Contributes to improved visibility. Furthermore, the light from the thin film light-emitting part 12 is bright, and the light from the thick film light-emitting part 14 is softly reflected, and the thin film light-emitting part 12 and the thick-film light-emitting part 14 are harmonized to produce a visually excellent effect. Visibility at far / near and front / side is improved.
후막투광부(14)의 두께에 대해서는 특별한 제한은 없으나, 후막투광부는 빛이 측면으로 방출되기 위해서 박막투광부(12)보다 1.5~20배의 두께를 가지는 것이 바람직하다. 20배를 초과하면 외부로 방출되는 빛의 양이 너무 적게 되는 문제가 있다.The thickness of the thick film transmitting part 14 is not particularly limited, but it is preferable that the thick film transmitting part has a thickness of 1.5 to 20 times that of the thin film transmitting part 12 in order to emit light to the side surface. If it exceeds 20 times, there is a problem that the amount of light emitted to the outside is too small.
박막투광부(12)와 후광투광부(14)의 위치에 대해서는 특별한 제한은 없으나, 박막투광부(12)에서의 빛이 원거리까지 도달하기 위해서는 LED(1)에서 방출되는 빛의 직진성을 고려할 때, LED(1) 빛이 가장 강하게 방출되는 방향인 전면에 형성되는 것이 바람직하며, 후막투광부(14)는 박막투광부(12)의 주위에 설치되는 것이 바람직하다.There is no particular limitation on the positions of the thin film light emitting part 12 and the back light transmitting part 14, but when considering the straightness of the light emitted from the LED 1 to reach the distance from the thin film light emitting part 12 to a long distance. Preferably, the LED 1 is formed on the front surface in which the light is most strongly emitted, and the thick film light-emitting portion 14 is preferably installed around the thin film light-emitting portion 12.
또한 박막투광부(12)와 후막투광부(14)의 갯수에 대해서는 특별한 제한은 없으며, 필요에 따라서는 여러개를 형성할 수도 있다. The number of the thin film light emitting part 12 and the thick film light transmitting part 14 is not particularly limited, and may be formed as many as necessary.
투광부(10)의 전체적인 형태에 대해서는 특별한 제한은 없다. 도 2에서는 사면체를 기준으로 도시하였지만, 필요에 따라서는 삼면체, 오면체, 육면체, 반구형등등의 다양한 입체적인 형상을 가질 수도 있다. 도 4는 다양한 입체적인 형상의 예시로서 반구형의 형상을 가지는 투광부를 도시하였다. There is no particular limitation on the overall shape of the light transmitting part 10. Although shown in FIG. 2 with reference to a tetrahedron, if necessary, it may have various three-dimensional shapes, such as a trihedron, a pentagon, a hexahedron, and a hemispherical shape. 4 illustrates a light transmitting unit having a hemispherical shape as an example of various three-dimensional shapes.
또한 박막투광부(12)와 후막투광부(14)를 위에서 보았을 때의 형태에 대해서는 특별한 제한은 없다. 일반적으로 원형을 이루게 되지만, 경우에 따라서 별, 삼각형, 사각형, 동물문양, 사람형상, 글자모양 등등을 포함하는 특정한 도형이나 문자의 형태를 가질 수도 있다. 이 경우에 박막투광부(12) 또는 후막투광부(14)에 형성되어 있는 도형이나 문자의 형태를 외부에서 인식할 수 있게 된다. In addition, there is no restriction | limiting in particular about the form at the time of seeing the thin film light transmission part 12 and the thick film light transmission part 14 from the top. In general, it is circular, but in some cases, it may have a specific shape or character, including stars, triangles, squares, animal patterns, human figures, letters, and the like. In this case, it is possible to recognize the shape of a figure or a character formed in the thin film light emitting part 12 or the thick film light transmitting part 14 from the outside.
박막투광부(12)는 투광부의 두께가 상대적으로 얇은 부분을 의미하므로, 박막투광부(12)는 먼저 투광부를 형성하고 다음으로 투광부에서 박막투광부(12)에 해당하는 부분을 음각하는 방식에 의해 구현될 수 있다. 도 5는 박막투광부(12)가 음각된 것을 보여주는 도면이다. 도 5(a) 내지 (d)에서 보는 바와 같이, 박막투광부(12)는 투광부에서 음각이 된 부분이고, 그 이외의 부분은 후막투광부(14)가 된다. Since the thin film light emitting part 12 means a portion where the thickness of the light transmitting part is relatively thin, the thin film light transmitting part 12 first forms the light transmitting part and then inclines the portion corresponding to the thin film light emitting part 12 in the light transmitting part. It can be implemented by. 5 is a view showing that the thin film light-transmitting portion 12 is engraved. As shown in Fig. 5 (a) to (d), the thin film light-transmitting portion 12 is a portion engraved in the light-transmitting portion, the other portion is the thick film light-transmitting portion (14).
또한 후막투광부(14)는 투광부의 두께가 상대적으로 두꺼운 부분을 의미하므로, 후막투광부(14)는 투광부를 형성하고 투광부에서 후막투광부(14)에 해당하는 부분을 양각하는 방식에 의해 구현될 수 있다. 도 6은 후막투광부(14)가 양각된 것을 보여주는 도면이다. 도 6(a) 내지 (d)에서 보는 바와 같이, 후막투광부(14)는 투광부에서 양각이 된 부분이고, 그 이외의 부분은 박막투광부(12)가 된다. 도 6의 경우에는 후막투광부(14)가 중앙에 위치하고 박막투광부(12)가 그 주위에 위치하는 것을 보여주는 도면이다.In addition, since the thick-film light-emitting part 14 means a portion where the thickness of the light-transmitting part is relatively thick, the thick-film light-emitting part 14 forms a light-transmitting part and by embossing a portion corresponding to the thick-film light-emitting part 14 in the light-transmitting part. Can be implemented. 6 is a view showing that the thick-film light-transmitting portion 14 is embossed. As shown in Figs. 6 (a) to 6 (d), the thick film light transmitting portion 14 is an embossed portion of the light transmitting portion, and the other portion becomes the thin film light transmitting portion 12. In the case of FIG. 6, the thick-film light-emitting part 14 is positioned at the center and the thin-film light-emitting part 12 is positioned around it.
나아가 양각과 음각을 적절하게 조합하여서 박막투광부(12)와 후막투광부(14)가 여러개 존재하게 만들 수도 있다. 도 7은 다수의 박막투광부(12)와 후막투광부(14)가 존재하는 LED 어셈블리의 예시도이다. 도 7(a)와 도 7(b)에서 보는 바와 같이, 중앙에 위치하는 양각이 된 후막투광부(14')와 가장자리에 위치하는 다른 후막투광부(14'')가 존재하고 그 사이로 음각이 된 박막투광부(12)가 존재하고 있다. 따라서 외부에서 보면 도 7(a)의 경우에는 중앙의 원(14')와 가장자리의 원(14'')사이의 박막투광부(12)가 가장 밝게 보이는 효과가 있고, 도 7(b)의 경우에는 중앙의 별(14')와 가장자리의 사각형(14'')사이의 공간인 박막투광부(12)가 가장 밝게 보이는 효과가 있다. 도 5 내지 도 7은 투광부의 상부의 평평한 부분만 도시한 것이다.Furthermore, by appropriately combining the relief and the intaglio, it is also possible to have a plurality of the thin film light-emitting portion 12 and the thick film light-transmitting portion 14 present. 7 is an exemplary view illustrating an LED assembly in which a plurality of thin film light emitting parts 12 and a thick film light transmitting part 14 are present. As shown in Figs. 7 (a) and 7 (b), there is an embossed thick film projection portion 14 'positioned at the center and another thick membrane projection portion 14 " positioned at the edge, and there is an intaglio therebetween. The thin film light-emitting part 12 which existed exists. Therefore, when viewed from the outside, the thin film light-emitting portion 12 between the central circle 14 'and the circular circle 14' 'at the edge has the brightest effect. In this case, the thin film light emitting part 12, which is a space between the central star 14 'and the square 14 " 5 to 7 show only the flat portion of the upper portion of the light transmitting portion.
또한 LED 발광장치의 시각적인 효과를 강조하기 위하여 박막투광부(12)나 후막투광부(14)에는 색이 칠해질 수도 있다. 여기서 박막투광부(12)와 후막투광부(14)는 동일한 색으로 칠해질 수도 있으나, 서로 다른 색으로 칠해질 수도 있다. 또한 박막투광부(12)와 후막투광부(14)에 여러개의 색이 동시에 칠해질 수도 있다. 나아가 박막투광부(12)와 후막투광부(14)의 외부에만 색이 칠해질 수도 있다. 또한 LED와 투광부의 색깔을 서로 동일하게 하거나 서로 다르게 하여 하나의 LED에서 방출되는 빛을 다양하게 표현할 수 있다. In addition, in order to emphasize the visual effect of the LED light emitting device, the thin film light emitting part 12 or the thick film light transmitting part 14 may be colored. Here, the thin film transmitting part 12 and the thick film transmitting part 14 may be painted in the same color, or may be painted in different colors. In addition, a plurality of colors may be painted on the thin film light emitting part 12 and the thick film light transmitting part 14 simultaneously. Furthermore, the color may be painted only on the outside of the thin film transparent part 12 and the thick film transparent part 14. In addition, the colors emitted from one LED may be variously expressed by making the colors of the LED and the light emitting part the same or different from each other.

The base may be formed in various forms, but basically has a structure that can be in close contact with the light-transmitting part, but also to accommodate the LED inside to protect the LED from external shocks. FIG. 8 is a cross-sectional view of the LED assembly with a base, and FIG. 9 is a plan view of the LED assembly with the light transmitting portion removed. The base 70 includes a base 71, a side wall 73 and a wire connecting groove 76. The support portion 71 is formed with a rim 72 larger than the diameter of the fixing portion 30. The side wall 73 is a portion protruding upward from the base 71, and the light transmitting portion is coupled to the side wall. Therefore, coupling means such as screw grooves or coupling jaws may be formed on the sidewalls for coupling with the light transmitting portion. The side wall 73 generally has a cylindrical shape, and an inner space in which the LED is accommodated is formed in the side wall 73.
전선연결홈(76)은 받침부(71)를 관통하는 홈으로서, 이 부분으로 전선(미도시)이 연결된다. 전선연결홈(76)은 고정부(30)에 형성되어 있는 LED(1)의 양극과 음극으로 전선이 지나갈 수 있는 위치에 형성되어야 한다. 고정부(30)의 양극과 음극에는 각각 수직방향으로 연결나사(35)가 결합되어 있는데, 연결나사(35)는 고정부(30)를 수직방향으로 관통하게 된다. 전선연결홈(76)에 삽입된 전선은 피복이 벗겨지지 않은 상태로 삽입되며, 상기 연결나사(35)가 회전하면서 전선연결홈(76)에 삽입된 전선의 피복을 관통하여 LED의 양극과 음극은 각각 전선에 전기적으로 연결된다.

Are each electrically connected to a wire.
종래에는 LED와의 연결을 위하여 전선의 피복을 제거하여야 하므로 번거롭고, 또한 일단 설치된 LED의 위치를 변경하는 경우에는 전선을 추가로 연결하거나 전선이 남아서 늘어져서 외관상 안 좋았으나, 본 발명에서의 베이스를 이용하게 되면 연결이 간단할 뿐 아니라 LED 위치 변경시에는 단순히 연결나사를 풀고 LED의 위치를 변경한 후에 다시 연결나사를 조이면 되므로 종래와 같이 전선이 남아서 늘어지거나 부족하여 추가적으로 전선을 연결할 필요가 없게 된다.In the related art, it is cumbersome to remove the covering of the wire for connection with the LED, and in the case of changing the position of the LED once installed, the wire is additionally connected or the wire is left to be stretched. If the connection is simple, when changing the LED position, simply loosen the connection screw, change the position of the LED, and then tighten the connection screw again.

In this case, there is an open lower opening 78 at the lower part of the base 70, and the lower opening 78 is a form in which the LED can be inserted. In the case of the base 70 in which the lower opening 78 is formed, the wire connection groove is not installed. The method of coupling this to the upper plate 3100 is to combine the base 70 and the light emitting unit 30 in the upper light emitting hole 3110 by inserting the LED through the lower opening 78.
LED 어셈블리는 지지층(3000)에 부착시키는 방법에 대하여 설명한다. 이는 LED 어셈블리가 전체가 일체형으로 제작된 경우 및 투광부와 LED가 서로 분리되게 제작된 경우에 따라 서로 상이하다.A method of attaching the LED assembly to the support layer 3000 will be described. This is different from each other in the case where the LED assembly is made integrally with the whole and when the light transmitting part and the LED are made to be separated from each other.

다른 부착방법으로는 상판(3100)에 일정한 간격으로 다수의 상판발광공(3110)을 내고, 상기 상판발광공(3110)에 LED 어셈블리(100)를 끼워넣는 것이다. 통상적으로 이러한 결합방식을 뒤 끼우기 방식이라 한다. 이 경우에 상판발광공의 직경이 투광부의 직경과 같거나 작게 하여서 투광부를 상판발광공에 끼우면 투광부가 상판발광공에 완전히 끼인 상태가 될 수 있도록 한다. As another method of attachment, the top plate 3100 emits a plurality of top light emitting holes 3110 at regular intervals, and the LED assembly 100 is inserted into the top light emitting hole 3110. Typically, such a coupling method is called a back fitting method. In this case, when the diameter of the top emitting hole is equal to or smaller than the diameter of the light emitting part, the light transmitting part is inserted into the top emitting hole so that the light transmitting part is completely caught in the top emitting hole.

The recessed portion is in contact with the side surface of the LED 1 and the outside is in contact with the upper plate light emitting hole 3110. To this end, the top emitting hole 3110 should have a diameter slightly larger than that of the recess 90 but smaller than the diameter of the light transmitting portion 10 adjacent to the recess 90.
반면에 투광부(10)와 LED(1)가 분리된 경우에는 도 15와 같이, 상판(3100)에 형성된 상판발광공(3110)의 상부에 투광부(10)를 두고, 상판발광공(3110)의 하부에 LED(1)부분을 하부에서 상부로 끼우는 형식으로 밀어서 투광부(10)와 결합시키면 된다. 이를 통상적으로 앞 끼우기 방식이라 하며, 상판은 투광부와 고정부 사이에 고정된다. 이 경우에 LED(1)와 투광부(10)는 밀착하게 되어 고정된다. 물론 반대로 상판발광공(3110)의 하부에 LED(1)를 먼저 끼우고 상부에 투광부(10)를 결합시킬 수 도 있다. 또한 베이스가 있는 경우에는 베이스를 상판발광공에 끼워져서 투광부(10)와 결합하게 된다.

In this case, the LED 1 and the light projecting portion 10 are brought into close contact and fixed. Of course, on the contrary, the LED 1 may be inserted into the lower portion of the upper light emitting hole 3110 and the light emitting portion 10 may be coupled to the upper portion. In addition, when the base is present, the base is fitted into the upper plate emitting hole to be combined with the light transmitting part 10.
