Description

엘이디를 이용한 실내 조명장치{A Lighting Fixtures with Light Emitting Diode}Indoor lighting device using LEDs {A Lighting Fixtures with Light Emitting Diode}

본 발명은 LED(Light Emitting Diode: 이하 "엘이디"라 한다.)의 광원이 그 각도가 조절되는 도광판을 통하여 고정설치되는 반사면에 반사되어 광원의 중심각을 자유롭게 조절하도록 하는 엘이디를 이용한 실내 조명장치에 관한 것이다.The present invention is an indoor lighting apparatus using the LED to allow the light source of the LED (Light Emitting Diode: referred to as "LED") is reflected on the reflective surface fixed through the light guide plate whose angle is adjusted to freely adjust the center angle of the light source. It is about.

일반적으로, 야간이나 실내에서 사용되는 조명등은 전원을 공급받아 전기에너지를 빛에너지로 변환시키는 조명등으로 사용되는 것으로는 백열전구나 형광등이 사용된다. In general, an incandescent lamp or a fluorescent lamp is used as a lamp used at night or indoors to be used as a lamp for converting electrical energy into light energy by receiving power.

이때, 상기 백열전구는 색감이 따뜻하고 점등에 부속장치가 필요 없으며, 또한 조명기구와의 조합이 용이하여 형광등의 보급에도 불구하고 여전히 수요비중이 큰데, 이들 백열전구나 형광등은 수명이 짧고, 소비전력이 매우 높다.At this time, the incandescent light bulb is warm in color and does not require an accessory for lighting, and also easy to combine with lighting fixtures, despite the widespread use of fluorescent lamps, there is still a large share of demand, these incandescent lamps or fluorescent lamps have a short life and very power consumption high.

한편, 형광등은 필라멘트를 사용하는 백열전구에 비해 효율이 높고 수명이 긴 장점이 있어 백열전구와 함께 대중적으로 사용되고 있다.On the other hand, fluorescent lamps have a high efficiency and long life compared to incandescent bulbs using filaments, and thus are widely used with incandescent bulbs.

또한, 최근에는 할로겐사이클을 이용한 요오드 전구, 고효율 헬라이드등, 양광램프 등이 개발되고 실용화되고 있으며, 결정발광체인 EL램프는 면광원으로 차세 대 광원으로 각광받고는 있지만 효율이나 광원장치 등의 문제로 아직 실용화단계까지 도달하지는 못하였다.In addition, recently, iodine bulbs, high-efficiency halide lamps, and photovoltaic lamps using halogen cycles have been developed and put into practice. EL lamps, which are crystal light emitters, have been spotlighted as next-generation light sources. It has not yet reached the commercialization stage.

한편, 엘이디는 종래의 광원에 비해 소형이고, 수명이 길며, 전기에너지가 빛에너지로 직접 변환하기 때문에 전력이 적게 들고 효율이 좋은 것으로 알려져 있으나, 빛의 직진성은 우수한 반면 확산성이 좋지 못하여 넓은 면적을 고르게 조사해주어야 하는 일반 실내등으로는 부적합하였으며, 이로 인해 휴대용 랜턴과 같은 소형 전등으로는 개발되어 사용되고는 있으나, 아직까지는 일반 가정에서 실내 조명용으로 사용하기에 적합한 제품은 개발되어 있지 않은 실정이다.On the other hand, LEDs are known to be smaller and have a longer lifespan than conventional light sources, and have low power and good efficiency because electrical energy is directly converted into light energy. Although it is not suitable for general indoor lighting that needs to be irradiated evenly, it has been developed and used as a small lamp such as a portable lantern, but there are no products suitable for use for indoor lighting in general homes.
