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

본 발명은 형광등형 엘이디 전등에 관한 것이다. The present invention relates to a fluorescent lamp-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, by producing a light using an LED as a light source in the form and size of fluorescent lamp that is used in the existing, the present invention relates to a fluorescent lamp-type LED lamp to be easily used to replace the fluorescent lamp, which is currently being used.

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 light is been not only easily available from most supermarkets and electronics store, the price is also affordable, the longest in the entire lighting industry, as well as the easy way to install all ages signage industry and use the most.

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, in the case of fluorescent lamps were replaced frequent in sunspot phenomena, short life, etc., there is a limit to the colors, shapes and designs represented, because it uses a fluorescent material so runs counter to the flow of the lighting market oriented environment-friendly and replaced gradually by other sources 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. As is most attention LED (LED, Light Emitting Diode) device as the other light source, which is the beginning to the commercialization of red LEDs using GaAsP compound semiconductor 1962 GaP: with the green LED of the N series of information and communication equipment so far including has been used as the light source for the display of the electronic device.

또한, 1990년대 중반 이후, GaN 청색 엘이디가 개발되면서 천연색 디스플레이가 가능하게 되었다. In addition, since the mid-1990s, while GaN blue LED was developed to enable a multi-colored display.

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. A typical use of the field, be a liquid crystal display device and keypad backlights for mobile phones which, in addition to the outdoor large billboard, traffic lights, automotive instrument panels and taillights, ports, airports, warning and guide lights of the skyscrapers, has been used in various places.
