Description

엘이디 전구{LED bulb light}LED bulb {LED bulb light}

본 고안은 실내 조명이나 장식의 목적으로 이용되는 전구에 관한 것이며, 더욱 상세하게는 빛을 발하는 광원으로서 발광다이오드를 이용한 LED전구에 관한 것이다.The present invention relates to a light bulb used for the purpose of indoor lighting or decoration, and more particularly to an LED bulb using a light emitting diode as a light emitting light source.

빛으로서 실내를 장식하고 밝게 하기 위한 인공광원으로는 여러 것들이 제공되어 있다.Several sources of artificial light are provided to decorate and brighten the interior as light.

그중 백열전구는 따스하고 아늑한 빛과 접등에 부속장치가 필요 없으며, 또한 조명기구와의 조합이 손쉬워서, 효율·수명·광색 등이 우수한 형광등의 급격한 보급에도 불구하고 수요비중이 크다. 특히 주택에서는 아늑한 분위기조성·점등의 간편성 등으로 널리 활용되고 있다.Among them, incandescent lamps do not need any accessories for warm and cozy light and entertainment, and the combination with lighting fixtures is easy. In particular, houses are widely used for creating a cozy atmosphere and convenience of lighting.

형광등은 1938년에 미국의 인맨에 의하여 발명된 것으로 효율·수명·광색 등의 우수한 특성으로 인하여 빌딩·공장·상점으로부터 주택에 이르기까지 널리 쓰이고 있다. 수은등이나 나트륨등은 형광등보다 이전에 발명된 것이지만, 연색성(演色性) 문제로 실용화가 늦어졌다. 그러나, 고효율·긴수명 등의 특성으로 현재에는 높은 천장의 공장, 경기조명·도로조명으로 많이 쓰이고 있다. 최근의 광원으로는 할로겐사이클을 이용한 요오드전구·고효율 헬라이드등·양광램프 등이 개발되어 실용화되고 있다.Fluorescent lamps were invented by Inman in the United States in 1938 and are widely used in buildings, factories, shops, and houses because of their excellent properties such as efficiency, lifespan, and color. Mercury lamps and sodium lamps were invented earlier than fluorescent lamps, but their use has been delayed due to color rendering problems. However, due to its high efficiency and long life, it is now widely used as a factory with high ceiling, Gyeonggi lighting and road lighting. Recently, iodine bulbs, high-efficiency halide lamps, and solar lamps using halogen cycles have been developed and put into practical use.

결정발광체인 전기루미네선스(EL)램프는 면광원으로 각광을 받고 있지만, 효율·광원장치 등의 문제로 실용화에는 이르지 못하고 있다. 이러한 인공광원은, 인류와 오랜 세월 친숙된 태양광을 목표로 발달되어 왔다. 연색성 등 다소 결점은 있으나, 일정한 광도를 유지할 수 있다는 특성은, 태양광에 비하여 확실히 우수하다.인간은 인공광원에 의하여 생활의 장을 시간적으로나 장소적으로 넓혀 왔다.Electroluminescence (EL) lamps, which are crystal emitters, are in the spotlight as surface light sources, but have not been put to practical use due to problems such as efficiency and light source devices. This artificial light source has been developed with the aim of solar light which has been familiar with mankind for many years. Although there are some drawbacks such as color rendering, the property of maintaining a constant brightness is certainly superior to sunlight. Humans have extended the field of life in time and place by artificial light sources.

한편, 발광다이오드(LED)는 종래의 광원에 비해 소형이고, 수명은 길며, 전기에너지가 빛에너지로 직접 변환하기 때문에 전력이 적게 들고 효율이 좋은 것으로 알려져 있다. 또한 고속응답이라 자동차 계기류의 표시소자, 광통신용광원 등 각종 전자기기의 표시용 램프, 숫자표시 장치나 계산기의 카드 판독기 등에 쓰이고 있다.On the other hand, light emitting diodes (LEDs) are known to have a small power, a long lifespan, and low electric power and good efficiency since electrical energy are directly converted into light energy. In addition, it is used in display devices of automotive instrumentation, display lamps of various electronic devices such as optical communication light sources, numeric display devices, and card readers of calculators.

그러나 이러한 장점을 가지고 있는 발광다이오드는 전기 전자 기구에서 신호의 표시를 위한 수단으로서 이용되고 있을 뿐 일상 생활에서 조명등으로서 이용하기에 적당하도록 제공된 것은 없는 것이다.However, the light emitting diode having such an advantage is used as a means for displaying signals in electric and electronic devices, but is not provided to be suitable for use as a lighting lamp in everyday life.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 제공된 것으로서 그 목적으로 하는 것은 광원으로서 발광다이오드를 이용하고 또 일반 주택이나 건물에서 기존에 제공되어 있는 소켓에 결합하여 이용할 수 있도록 하여 전력소모를 최소화 할 수 있으면서도 조명효율이 우수한 LED전구를 제공하는 것에 있다.The present invention is provided to solve the above-mentioned conventional problems, and its purpose is to use a light emitting diode as a light source and to be used in combination with a socket provided in a conventional house or building to minimize power consumption. The present invention is to provide an LED light bulb which is capable of lighting and has excellent lighting efficiency.
