Description

형광등형 엘이디 전등{LED electric lamp type fluorescent lamp}Fluorescent lamp type LED lamp {LED electric lamp type fluorescent lamp}

본 발명은 형광등형 엘이디 전등에 관한 것이다.The present invention relates to a fluorescent type LED lamp.

더욱 상세하게는 엘이디를 광원으로 사용하는 전등을 기존에 사용하고 있는 형광등의 형태 및 규격으로 제조함으로써, 현재 사용하고 있는 형광등을 대체시켜 용이하게 사용될 수 있도록 한 형광등형 엘이디 전등에 관한 것이다.More specifically, the present invention relates to a fluorescent lamp type LED lamp that can be easily used by replacing a fluorescent lamp currently used by manufacturing a lamp using an LED as a light source in the form and specification of a conventional fluorescent lamp.

형광등은 일반 슈퍼나 전파사에서 손쉽게 구입할 수 있을 뿐만 아니라, 가격도 저렴하고 남녀노소 설치방법이 쉬워 간판 업계뿐만 아니라 전 조명업계에서 가장 오랫동안 그리고 가장 많이 사용되어진 광원이다. Fluorescent lamps are not only easy to buy at supermarkets and radio companies, but are also cheap and easy to install for both sexes, making them the longest and most used light source in the lighting industry.

그러나 형광등의 경우 흑점 현상, 짧은 수명 등으로 교체가 잦으며, 색, 형태 등 디자인 표현에 한계가 있고, 형광물질을 사용하기 때문에 친환경을 지향하는 조명시장의 흐름에 역행하므로 점차 타 광원으로 대치되고 있는 추세이다.However, fluorescent lamps are often replaced by dark spots and short lifespan, and there are limitations in design expression such as color and shape, and they are gradually replaced by other light sources because they use the fluorescent material, which is contrary to the trend of eco-friendly lighting market. There is a trend.

타 광원으로 가장 주목받고 있는 것은 엘이디(LED, Light Emitting Diode)소자로서, 이는 1962년 GaAsP 화합물 반도체를 이용한 적색 엘이디가 상품화된 것을 시작으로 GaP:N 계열의 녹색 엘이디와 함께 지금까지 정보통신기기를 비롯한 전자장치의 표시용 광원으로 이용되어 왔다. LED (Light Emitting Diode) device that is attracting the most attention as other light sources, which began with the commercialization of red LEDs using GaAsP compound semiconductors in 1962, together with GaP: N series green LEDs, It has been used as a light source for display of electronic devices.

또한, 1990년대 중반 이후, GaN 청색 엘이디가 개발되면서 천연색 디스플레이가 가능하게 되었다. In addition, since the mid-1990s, GaN blue LEDs have been developed to enable natural color displays.

대표적인 이용분야로는, 핸드폰의 액정표시소자와 키패드용 백라이트를 들 수 있으며, 이외에도 옥외용 대형 전광판, 교통 신호등, 자동차 계기판 및 후미등, 항만, 공항, 고층 빌딩의 경고 및 유도등으로, 다양한 곳에 사용되고 있다. Representative applications include a liquid crystal display device and a backlight for a keypad of a mobile phone, and are also used in various places such as outdoor large billboards, traffic signals, automobile dashboards and taillights, harbors, airports, and high-rise buildings.

또한, 엘이디는 반도체의 빠른 처리 속도와 낮은 전력 소모 등의 장점과 함께, 환경 친화적이면서도 에너지 절약 효과가 높아서 차세대 국가 전략 품목으로 꼽히고 있다. In addition, LED is considered as a next-generation national strategic item because of its advantages such as high processing speed and low power consumption of the semiconductor, and environmentally friendly and high energy saving effect.

또한 엘이디의 장점은 기존의 광원에 비해 극소형이며, 소비전력이 적고, 수명이 기존의 전구에 비해 10배 이상이며, 빠른 반응속도로 기존의 광원에 비해 매우 우수한 특성을 나타낸다. 또한, 자외선과 같은 유해파의 방출이 없고, 수은 및 기타 방전용 가스를 사용하지 않아 환경 친화적인 광원이다.In addition, the advantages of the LED is very small compared to the conventional light source, the power consumption is low, the lifespan is more than 10 times than the conventional light bulb, and shows a very excellent characteristics compared to the conventional light source with a fast reaction speed. In addition, there is no emission of harmful waves such as ultraviolet rays, and it is an environmentally friendly light source because mercury and other discharge gas are not used.

그러나 엘이디는 에너지가 빛의 형태뿐만 아니라, 열의 형태로도 방출되기 때문에, 고온이 되기 쉬운 특성을 갖는다. 고온을 냉각시키기 위하여 엘이디 전등 외부에 통공을 구성하는 형태의 전등이 일부 있으나, 통공을 통하여 유입된 먼지나 기타 해충 등에 의해 엘이디 전등의 효율이 현저히 감소하게 된다. 또한, 발열로 인한 고온 때문에 엘이디의 수명이 줄어들므로, 엘이디의 발열을 냉각시키려는 연구는 지속적으로 수행되고 있다.LEDs, however, have the property of becoming hot because energy is emitted not only in the form of light but also in the form of heat. There are some types of lights that form a through hole outside the LED light to cool the high temperature, but the efficiency of the LED light is significantly reduced due to dust or other pests introduced through the through hole. In addition, since the lifetime of the LED is reduced due to the high temperature due to the heat generation, research to cool the heat generation of the LED has been continuously conducted.

또한, 엘이디의 광은 직진성이 있어 엘이디 바로 아래는 상당히 밝은 편이나 주변은 어두운 편이다. 따라서 일반 전등으로 사용하기 위해서는 엘이디의 직진성이 강한 광을 확산시킬 수 있는 별도의 장치가 필요하다.Also, the LED's light is straight, so it's fairly bright just below the LED, but dark around it. Therefore, in order to use as a general lamp requires a separate device that can diffuse the LED's strong light.

이에 따라서, 본 발명은 종래 기술의 문제점을 해소시키고, 필요성에 따라 안출된 것으로, 본 발명의 목적은 엘이디를 광원으로 사용하는 형광등 형상의 전등을 제작하는데 있어, 엘이디를 외부환경으로부터 격리시키는 외부 케이스의 일부를 방열부재로 제작함으로써, 상기 엘이디에서 발생하는 열을 효율적으로 제거할 수 있도록 하는 형광등형 엘이디 전등을 제공하는데 있다.Accordingly, the present invention solves the problems of the prior art, and the invention is devised according to the necessity, the object of the present invention is to produce a fluorescent lamp-shaped lamp using the LED as a light source, the outer case to isolate the LED from the external environment By manufacturing a portion of the heat dissipation member, to provide a fluorescent lamp type LED lamp that can efficiently remove the heat generated from the LED.

A 59 is attached and provided, and the waterproof member 59 includes a waterproof tape or the like.

상기 엘이디(10)를 광원으로 사용하는 형광등형 엘이디 전등의 작동전압은 100~240V이다.The operating voltage of the fluorescent type LED lamp using the LED 10 as a light source is 100 ~ 240V.

상기와 같이 구성된 형광등형 엘이디 전등의 작용에 대해 설명하면 다음과 같다.Referring to the operation of the fluorescent LED lamp configured as described above are as follows.

먼저, 도 4에 도시된 바와 같이 회로기판(15)에 복수개의 엘이디(10)가 소정 간격으로 이격되어 배열된다. 즉, 상기 복수의 엘이디(10)는 도 5에 도시된 바와 같이 엘이디(10)에서 방출되는 광이 중첩될 수 있도록 이격 된다. First, as shown in FIG. 4, a plurality of LEDs 10 are arranged on the circuit board 15 at predetermined intervals. That is, the plurality of LEDs 10 are spaced apart from each other so that the light emitted from the LEDs 10 may overlap with each other.

그리고 상기 엘이디(10)로부터 방출되는 광의 중첩 지점이 상기 확산커버(30)의 내측에 위치되도록 상기 회로기판(15)이 확산커버(30)와 이격된 상태에서 방열커버(20)에 결합된다.The circuit board 15 is coupled to the heat dissipation cover 20 in a state in which the circuit board 15 is spaced apart from the diffusion cover 30 so that the overlapping point of the light emitted from the LED 10 is located inside the diffusion cover 30.

이때 거리(d) 조정은 회로기판(15)의 두께를 조절함으로써, 회로기판(15)과 확산커버(30)의 이격 거리가 일정 거리를 유지할 수 있도록 구현할 수 있다. In this case, the distance d may be adjusted to adjust the thickness of the circuit board 15 so that the distance between the circuit board 15 and the diffusion cover 30 may be maintained at a predetermined distance.

상기와 같이 복수의 엘이디(10)에서 방출되는 광이 중첩되는 지점이 확산커버(30) 내측에 내측벽으로부터 가장 근접한 위치에 위치되도록 엘이디(10)가 확산커버(30)로부터 이격된 위치에 구비되도록 한다. As described above, the LED 10 is provided at a position spaced apart from the diffusion cover 30 such that a point where the light emitted from the plurality of LEDs 10 overlaps is positioned at a position closest to the inner wall inside the diffusion cover 30. Be sure to

상기와 같이 엘이디(10)와 확산커버(30) 사이의 거리를 결정해 줌으로써, 엘이디(10)가 점등될 경우 확산커버(30)의 외부 면에 엘이디(10)의 형상이나 잔상이 나타나지 않게 된다.By determining the distance between the LED 10 and the diffusion cover 30 as described above, when the LED 10 is lit, the shape or afterimage of the LED 10 does not appear on the outer surface of the diffusion cover 30. .

또한, 방열커버(20)는 외주면에 일정 간격으로 이격된 방열핀(21)이 구비되어 있으므로, 상기 엘이디(10)가 점등될 경우 상기 엘이디(10)에 의해 발생되는 열을 외부로 방출시켜 형광등 내부의 온도가 상승되지 않도록 되며, 방열커버(20)의 양 끝단부에는 도 2 및 도 3에 도시된 바와 같이 결합부재인 홈(25)이 형성되어 있다.In addition, since the heat dissipation cover 20 is provided with heat dissipation fins 21 spaced at regular intervals on the outer circumferential surface, when the LED 10 is turned on, the heat generated by the LED 10 is discharged to the outside to form a fluorescent lamp. The temperature of the heat dissipation cover 20 is not increased, and both ends of the heat dissipation cover 20 are formed with grooves 25, which are coupling members, as shown in FIGS. 2 and 3.

상기 결합부재인 홈(25)에는 확산커버(30)에 구비된 결합부재인 돌기(35)가 외부로부터 가압되는 힘에 의해 끼워지고, 이에 따라 방열커버(20)와 확산커버(30)가 상호 결합되어 튜브형태의 형광등 형상을 가지게 된다. 이때 상기 확산커버(30)는 그 자체에 확산물질이 포함되어 형성되었기 때문에 별도의 확산 판 또는 확산 필름 등과 같은 확산부재를 구비시키지 않아도 기존의 형광등과 같이 자연스러운 광이 확산되어 방출되도록 한다.The coupling member groove 25 is fitted into the coupling member 25 by the force applied from the outside, and thus the heat dissipation cover 20 and the diffusion cover 30 are mutually connected. Coupled to have a tube-shaped fluorescent lamp shape. In this case, since the diffusion cover 30 is formed by including a diffusion material in itself, the diffusion cover 30 does not have a diffusion member such as a diffusion plate or a diffusion film so that natural light is diffused and emitted like a conventional fluorescent lamp.

이때, 상기 방열커버(20)의 홈(25)에 확산커버(30)의 돌기(35)를 끼우기 전에 상기 방열커버(20)와 확산커버(30)가 밀착되는 면에 방수 테이프(70)를 부착시켜 내측으로 증기 등과 같이 수분이 침투되지 않도록 한다.In this case, before inserting the projection 35 of the diffusion cover 30 into the groove 25 of the heat dissipation cover 20, the waterproof tape 70 is placed on a surface in which the heat dissipation cover 20 and the diffusion cover 30 are in close contact with each other. To prevent moisture from penetrating inside such as steam.

상기 결합된 상태에서 상기 방열커버(20)와 확산커버(30)에서 결합되어 형성된 튜브형태의 양 끝단에 전기연결부(50)를 먼저 끼우고, 상기 전기연결부(50)의 상부에 마감캡(40)을 씌워 상기 전기 연결부(50)가 외부 환경으로부터 격리되도록 한다. 이때 상기 마감캡(40)에는 상기 전기 연결부(50)와 전기적으로 결합되고, 상용전원을 공급받아 상기 전기 연결부(50)를 통해 엘이디 구동부(17)로 엘이디의 구동전원을 출력하는 전원핀(43)이 구비된다(도 1 및 도 2 참조).In the coupled state, the electrical connection portion 50 is first inserted into both ends of the tube shape formed by being coupled to the heat dissipation cover 20 and the diffusion cover 30, and a closing cap 40 on the upper portion of the electrical connection portion 50. ) So that the electrical connection 50 is isolated from the external environment. At this time, the closing cap 40 is electrically coupled with the electrical connector 50, the power supply pin 43 for outputting the driving power of the LED to the LED driver 17 through the electrical connector 50 is supplied with commercial power supply ) Is provided (see FIGS. 1 and 2).

이때, 상기 방열커버(20)와 밀착되는 전기 연결부(50)의 돌기(55) 외주면에 방수테이프(57)가 부착되고, 상기 확산커버(30)와 밀착되는 전기 연결부(50)의 홈(58) 내주면에 방수 테이프(59)가 부착되어 있으므로, 상기 전기연결부(50)가 상기 방열커버(20) 및 확산커버(30)에 더욱 밀착 결합되는 한편, 결합틈 사이로 공기 중에 있는 수분이 침투되지 않도록 한다.In this case, the waterproof tape 57 is attached to the outer circumferential surface of the protrusion 55 of the electrical connection part 50 in close contact with the heat dissipation cover 20, and the groove 58 of the electrical connection part 50 in close contact with the diffusion cover 30. Since the waterproof tape 59 is attached to the inner circumferential surface thereof, the electrical connection part 50 is more closely coupled to the heat dissipation cover 20 and the diffusion cover 30, and the moisture in the air does not penetrate between the coupling gaps. do.
