Description

진공 구조를 갖는 ＬＥＤ 형광등{LED Fluorescent Lamp Having Vacuum Structure}LED Fluorescent Lamp Having Vacuum Structure

본 발명은 진공 구조를 갖는 LED 형광등에 관한 것으로서, 보다 상세하게는 광확산 파이프를 일체형으로 개선하여 내부가 진공상태가 되도록 소켓과 결합하여 방수, 방습 기능을 가지는 진공 구조를 갖는 LED 형광등에 관한 것이다.The present invention relates to an LED fluorescent lamp having a vacuum structure, and more particularly, to an LED fluorescent lamp having a vacuum structure having a waterproof and moisture-proof function by combining with a socket so that the light diffusion pipe is integrally formed so that the inside thereof becomes a vacuum state. .

발광 다이오드(Light Emitting Diode, 이하 'LED'라 함)는 소형의 광원으로 소비전력이 적고 수명이 기존 광원보다 10배 이상 긴 특성이 있다. 또한 전기에너지가 빛 에너지로 직접 변환되어 빠른 반응 속도를 가진다. Light emitting diodes (LEDs) are small light sources that consume less power and have a lifespan that is 10 times longer than conventional light sources. In addition, electrical energy is converted directly into light energy, which has a fast reaction speed.

최근 자외선과 같은 유해파의 방출이 없고, 수은 및 기타 방전용 가스를 사용하지 않아 환경 친화적 광원으로 LED를 광원으로 하는 다양한 조명기구가 개발되고 있다.Recently, there is no emission of harmful waves such as ultraviolet rays, and mercury and other discharge gas are not used, and various lighting apparatuses using LED as a light source as an environmentally friendly light source have been developed.

특히 LED 형광등은 종래 형광물질을 사용하는 형광등보다 전력소비량이 20%에 불과하여 다양한 분야에 적용하기 위하여 개발되고 있다. 그러나, LED는 에너지가 빛의 형태 뿐만 아니라 열의 형태로도 방출되기 때문에 고온이 되기 쉬운 문제점이 있다. 이러한 방열 문제를 해결하기 위하여 종래의 LED 형광등(10)은 도 1에 도시된 내부 구조 사시도와 도 2의 단면도에 도시된 바와 같이 광원인 LED(13)가 회로기판(14) 상에 복수개 실장되어 있는 LED 모듈(12)과, LED 빛을 확산시켜 주는 광확산 파이프(11), 그리고 LED(13)에서 나오는 열을 흡수하여 이를 외부로 방출하는 HEAT SINK 역할을 하는 프레임(15)으로 구성된다.In particular, LED fluorescent lamps have been developed to apply to various fields because the power consumption is only 20% than fluorescent lamps using conventional fluorescent materials. However, LEDs have a problem of high temperature because energy is emitted not only in the form of light but also in the form of heat. In order to solve the heat dissipation problem, a conventional LED fluorescent light 10 has a plurality of LEDs 13 mounted on a circuit board 14 as a light source as shown in a perspective view of the internal structure of FIG. 1 and a cross-sectional view of FIG. 2. LED module 12, and a light diffusion pipe 11 to diffuse the LED light, and a frame 15 that serves as a heat sink to absorb the heat from the LED 13 and emit it to the outside.

상기 HEAT SINK 역할을 하는 프레임(15)이 단순히 LED 모듈(12)을 고정하고 상기 광확산 파이프(11)와 결합하기 위한 용도로만 사용되었다. 그래서 종래의 LED 형광등은 내부의 열이 외부로 배출되기 힘들기 때문에, 설치되는 장소의 온도가 LED 형광등과 온도 차이가 심하거나 습도가 높으면 설치가 힘들었다. 왜냐하면, 종래 LED 형광등의 내부 온도가 높아져서 외부와의 온도 차이가 커지면 형광등 내부에 습기가 차거나, LED 형광등의 프레임(15)과 광확산 파이프(11)의 결합 부분의 유격이나 소켓과 광확산 파이프(11)의 결합 부분을 통하여 외부로부터 습기가 침투되기 때문이다.The frame 15 serving as the heat sink is used only for fixing the LED module 12 and for coupling with the light diffusion pipe 11. Therefore, the conventional LED fluorescent lamp is difficult to be discharged to the outside heat inside, it is difficult to install if the temperature of the place where the installation is very different from the LED fluorescent lamp or the humidity is high. If the internal temperature of the conventional LED fluorescent lamp is increased and the temperature difference from the outside becomes large, moisture may be accumulated inside the fluorescent lamp, or the gap between the frame 15 of the LED fluorescent lamp and the light diffusion pipe 11 or the gap between the socket and the light diffusion pipe ( This is because moisture is penetrated from the outside through the engaging portion of 11).

상기의 문제점을 해결하기 위한 본 발명의 목적은, 일체형으로 형성된 광확산 파이프 내부에 다수의 LED가 형성된 LED 모듈과 PCB를 포함한 받침대가 형성되고 상기 광확산 파이프의 양측에 소켓이 내부 진공상태가 형성되도록 결합되어 방수, 방습의 진공 구조를 갖는 LED 형광등을 제공하기 위함이다. An object of the present invention for solving the above problems is, a pedestal including an LED module and a PCB formed with a plurality of LEDs are formed inside the light diffusion pipe integrally formed, and the sockets are formed on both sides of the light diffusion pipe in an internal vacuum state. In order to provide an LED fluorescent lamp that is combined to be waterproof and moisture-proof vacuum structure.

또한 본 발명의 목적은, 소켓의 일측에 탄성체결구를 형성하여 광확산 파이프 내부의 공기를 빼낸 후 상기 탄성체결구의 탄성으로 결합되어 외부 공기가 유입되지 않도록 진공 구조를 갖는 LED 형광등을 제공하기 위함이다. In addition, an object of the present invention is to provide an LED fluorescent lamp having a vacuum structure to form an elastic fastener on one side of the socket to remove the air inside the light diffusion pipe and then coupled to the elastic fastener so that the outside air is not introduced. .

또한 본 발명의 목적은, 형광등 내부가 중진공에서 고진공 사이를 유지하도록 하여 LED 구동으로 발생하는 기생 정전용량(Parasitic capacitance) 발생을 방지하여 발광효율을 향상시키도록 진공 구조를 갖는 LED 형광등을 제공하기 위함이다. In addition, an object of the present invention is to provide an LED fluorescent lamp having a vacuum structure to improve the luminous efficiency by preventing the generation of parasitic capacitance generated by driving the LED to maintain the interior of the fluorescent lamp between the medium and high vacuum. to be.
