이하, 본 발명에 따른 LED전광모듈의 바람직한 예를 첨부된 도면을 참조하여 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings a preferred example of the LED electroluminescent module according to the present invention will be described in detail.

본 발명에 따른 LED전광모듈은 LED의 빛을 모아 조다 선명하게 하고, 커버에 형성된 투광홀을 통해 이물질이나 빗물이 커버의 내부로 침투하는 것을 방지할 수 있게 한 것이 특징이다. LED electroluminescent module according to the present invention is characterized in that it collects the light of the LED to make it clear, and to prevent foreign matter or rainwater from penetrating the inside of the cover through the light-transmitting hole formed in the cover.

특히, 렌즈를 내구성이 우수한 실리콘 고무로 구성한 것이 특징이다. In particular, the lens is made of silicone rubber having excellent durability.

이러한 본 발명의 LED전광모듈은 다수의 LED칩(11)이 실장된 LED기판(1)과, 상기 LED기판(1)을 지지하는 사출케이스(2)를 포함하여 구성된 LED모듈에 있어서, 상기 LED기판(1)의 표면에는 LED기판을 보호하기 위한 커버(3)를 더 설치하되, 상기 커버(3)에는 LED칩(11)과 대향되는 부분에 실리콘 고무로 만들어진 렌즈(4)가 설치된 것이다. The LED electroluminescent module of the present invention comprises an LED substrate (1) on which a plurality of LED chips (11) are mounted, and an LED module including an injection case (2) supporting the LED substrate (1), wherein the LED A cover 3 for protecting the LED substrate is further provided on the surface of the substrate 1, and the cover 3 is provided with a lens 4 made of silicon rubber at a portion opposite to the LED chip 11.

상기 LED기판(1)과 사출케이스(2)는 이미 상기에서 설명한 바와 동일 유사한 구조를 갖는 것이나, 부연 설명하면, 상기 LED기판(1)은 도 3 및 도 5에 도시한 바와 같이, 다수의 LED칩(11)이 종, 횡으로 설치되어 있고, 상기 사출케이스(2)는 상기 LED기판(1)이 폭과 길이보다 멀고 길게 형성되어 있으며, 사출케이스(2)의 내벽에는 상기 LED기판(1)의 가장자리를 받쳐주는 턱이 형성되어 있다. The LED substrate 1 and the injection case 2 has a similar structure as described above, but in detail, the LED substrate 1 has a plurality of LEDs, as shown in FIGS. 3 and 5. The chip 11 is provided vertically and horizontally, and the injection case 2 is formed such that the LED substrate 1 is farther and longer than the width and length, and the LED substrate 1 is formed on the inner wall of the injection case 2. A chin is formed to support the edge of the).

또한 상기 사출케이스((2)의 내부에는 다수의 나사 고정용 돌출부가 형성되어 있고, 중앙에는 관통구멍이 형성되어 있어 공기가 출입할 수 있게 하여 LED기판에서 발생되는 열을 냉각시킬 수 있다. In addition, a plurality of screw fixing protrusions are formed in the injection case (2), and through holes are formed in the center thereof to allow air to enter and to cool the heat generated from the LED substrate.

이렇게 구성된 사출케이스(2)의 개방된 면에 상기 커버(3)가 착탈 가능하게 설치되어 안쪽에 설치된 LED기판(1)을 덮어 보호하는 것이다. The cover 3 is detachably installed on the open surface of the injection case 2 configured as described above to cover and protect the LED substrate 1 installed therein.

상기 커버(3)는 도 3에 도시한 바와 같이 다수의 렌즈(4)가 설치된다. The cover 3 is provided with a plurality of lenses 4 as shown in FIG.

상기 렌즈(4)가 설치되는 위치는 도시한 바와 같이, LED기판(1)에 설치된 각각의 LED칩(11)에 대응되는 부분이고, 커버(3)를 관통하여 형성된 투광홀(31)에 설치된다. The position where the lens 4 is installed is a portion corresponding to each LED chip 11 installed on the LED substrate 1, and is installed in the light-transmitting hole 31 formed through the cover 3, as shown. do.

상기 투광홀(31)은 상기 LED기판(1)에 설치된 LED칩(11)에서 발생된 빛이 외부로 조사되는 구멍으로서, 상기 렌즈(4)에 의해 밀폐된다. The floodlight 31 is a hole through which light generated from the LED chip 11 installed in the LED substrate 1 is irradiated to the outside, and is sealed by the lens 4.

즉, 투광홀(31)을 렌즈(4)로 밀폐하여 투광홀(31)을 통해 커버(3)으 안쪽으로 빗물이나 이물질이 들어가지 못하게 차단되는 것이다. That is, the light-transmitting hole 31 is sealed with the lens 4 to block rain or foreign matter from entering the cover 3 through the light-transmitting hole 31.

상기 렌즈(4)는 상기한 바와 같이 투명한 실리콘 고무로 만들어진다, The lens 4 is made of transparent silicone rubber as described above,

이와 같이 실리콘 고무로 렌즈(4)를 구성하는 이유는 실리콘 고무가 다른 합성수지나 고무보다 내구성이 우수하기 때문이다. The reason why the lens 4 is made of silicone rubber is that silicone rubber is superior in durability to other synthetic resins and rubber.

상기 렌즈(4)를 구성하는 실리콘 고무는 일명 규소 고무라고도 물리워지는 것으로서, 실리콘 오일보다 분자량이 크고, 200°C 공기 중에서 두드러진 물성의 저하는 없고 장시간의 사용에 견딜 수 있으며, 내열 사용온도 범위는 일반적으로 150~250°C 까지도 사용될 수 있으며, 내한성 또한 우수하며, 일반합성고무와는 달리 분자구조 내 대기중의 산소, 오존, 자외선등과 반응하여 균열을 일으키는 이중결합이 없기 때문에 내후성이 월등히 뛰어나 장기간 옥외에 방치하여도 물성 변화가 거의 없는 것이다. The silicone rubber constituting the lens 4 is also referred to as silicon rubber, which has a higher molecular weight than silicone oil, can withstand prolonged use without noticeable degradation of physical properties in air at 200 ° C, and a heat-resistant temperature range. Generally, it can be used up to 150 ~ 250 ° C, and also has excellent cold resistance, and unlike general synthetic rubber, weather resistance is excellent because there is no double bond that reacts with oxygen, ozone, ultraviolet light in the molecular structure and causes cracking. It is excellent and there is almost no change in physical properties even if it is left outdoors for a long time.

따라서, 상기와 같이 렌즈(4)를 실리콘 고무로 구성함으로써 전광모듈을 장시간 사용하여도 렌즈의 투명도가 손상되지 않아 LED칩(11)으로부터 발생된 빛이 외부로 조사되는 양을 그대로 유지하여 밝기가 유지되는 것이다. Therefore, since the lens 4 is made of silicone rubber as described above, even if the all-optical module is used for a long time, the transparency of the lens is not impaired, thereby maintaining the amount of light emitted from the LED chip 11 to the outside and maintaining the brightness. It is maintained.

상기 렌즈(4)를 커버에 설치하는 방법으로는 아래의 두 가지 방법이 사용될 수 있다. The following two methods may be used to install the lens 4 on the cover.

하나는 상기 렌즈(4)를 커버(3)를 사출할 커버 사출 금형의 해당 위치에 삽입한 후, 커버를 구성하는 재료를 투입하여 커버(3)를 사출하는 방법이고, 다른 하나의 방법은 커버(3)에는 투광홀(31)을 형성하고, 렌즈(4)만을 실리콘 고무로 별도로 제작하여 투광홀(31)에 끼워 설치하는 방법이다. One is a method of inserting the lens (4) in the corresponding position of the cover injection mold for ejecting the cover 3, and then injecting the material constituting the cover to eject the cover (3), the other method is a cover (3) is a method of forming a light-transmitting hole 31, and manufacturing only the lens 4 separately from silicone rubber and inserting it into the light-transmitting hole 31.

상기와 같이 커버(3)의 투광홀(31)에 설치되는 렌즈(4)가 투광홀(31)로부터 분리되지 않게 하기 위해서 상기 렌즈(4)에는 커버에 형성된 투광홀(31)의 가장자리가 끼워지는 결합홈(41)이 형성될 수 있다. In order to prevent the lens 4 installed in the light transmission hole 31 of the cover 3 from being separated from the light transmission hole 31, the edge of the light transmission hole 31 formed in the cover is fitted in the lens 4. Losing coupling groove 41 may be formed.

즉, 도 8에 도시한 바와 같이, 렌즈(4)의 일측 단부 외벽에 결합홈(41)을 형성하고, 이 결합홈(41)에 투광홀(31)의 가장지리에 벽이 끼어지게 함으로서 렌즈(4)가 커버(3)로부터 이탈되지 않게 하는 것이다. That is, as shown in FIG. 8, the coupling groove 41 is formed in the outer wall of one end of the lens 4, and the wall is sandwiched at the edge of the floodlight 31 by the coupling groove 41. This is to prevent the (4) from being separated from the cover (3).

물론, 상기 결합홈(41)은 렌즈(4)를 커버(3)와 일체로 사출하던가 따로 구성하여 조립하는 것과 관계없이 구성될 수 있다. Of course, the coupling groove 41 may be configured regardless of whether the lens 4 is integrally ejected from the cover 3 or assembled separately.

즉, 렌즈(4)를 커버(3)를 사출할 커버 사출 금형의 해당 위치에 삽입한 후, 커버를 구성하는 재료를 투입하여 커버(3)를 사출할 경우에도 렌즈(4)에 결합홈(41)을 형성하여 이 결합홈(41)에 커버 사출 재료가 틈입하게 하여 렌즈(4)와 커버의 결함이 돈독해지게 할 수 있는 것이다. That is, after inserting the lens 4 in the corresponding position of the cover injection mold to eject the cover 3, the material constituting the cover is injected into the lens 4 even when the cover 3 is ejected. 41 is formed so that the cover injection material can penetrate into the engaging groove 41 so that defects of the lens 4 and the cover can be strengthened.
