Description

색온도 조절이 가능한 엘이디 조명장치LED lighting device with adjustable color temperature
본 발명은 색온도 조절이 가능한 엘이디 조명장치로서, 엘이디로부터 방출되는 백색광의 색온도를 조절하여 다양한 색온도의 백색광을 구현할 수 있는 색온도 조절이 가능한 엘이디 조명장치에 관한 것이다.The present invention relates to an LED lighting device capable of adjusting the color temperature, and to an LED lighting device capable of adjusting the color temperature to realize the white light having various color temperatures by adjusting the color temperature of the white light emitted from the LED.
백색 발광다이오드(LED)는 기존에 사용하는 백열 전구에 비해 수명이 길고, 소형화가 가능하며, 저전압 구동이 가능하기 때문에 조명 분야 전반에 걸쳐 대체 광원으로서의 가능성을 인정받고 있다.White light emitting diodes (LEDs) have long life, miniaturization, and low voltage operation compared to incandescent bulbs, which have been recognized as potential light sources throughout the lighting field.
이러한 조명 분야를 대체하기 위한 백색광을 생성하는 엘이디는 빛의 삼원색인 적색, 녹색, 청색의 발광다이오드 칩을 한 패키지에 조합하여 제작한다. 그러나 이러한 백색광 생성방식은 각 색상별 발광다이오드가 넓은 스펙트럼 영역을 점유하지 못하기 때문에 연색 지수가 매우 낮고, 특정 색상의 발광다이오드의 수명이 짧아 조명을 장시간 사용하는데 문제점이 있다.LED, which produces white light to replace the lighting field, is manufactured by combining red, green, and blue light emitting diode chips, which are three primary colors of light, in one package. However, the white light generation method has a low color rendering index because the LEDs for each color do not occupy a wide spectral region, and there is a problem in using the lighting for a long time due to the short lifetime of the LEDs of a specific color.
백색광을 생성하는 다른 방법에는 InGaN계 청색 발광다이오드에 YAG계 형광체를 조합하는 방법이 있다. 이러한 엘이디 구조에서는 청색 발광다이오드에서 발생하는 청색광의 일부가 YAG계 형광체를 여기시켜 황록색의 형광을 발생하게 되며, 청색과 황록색이 합성되어 백색을 발광시킨다. 그러나 청색 발광다이오드에 YAG 형광체를 사용하는 방법은 발광다이오드의 청색과 형광체의 노란색과의 파장간격이 넓어서 색 분리로 인한 섬광효과로 인해 색좌표가 동일한 백색 발광다이오드의 양산이 어렵고, 색온도 조절이 어렵다.Another method of generating white light is to combine a YAG-based phosphor with an InGaN-based blue light emitting diode. In the LED structure, a part of the blue light generated from the blue light emitting diode excites the YAG-based phosphor to generate yellow green fluorescence, and blue and yellow green are synthesized to emit white light. However, the method of using the YAG phosphor in the blue light emitting diode has a wide wavelength interval between the blue of the light emitting diode and the yellow of the phosphor, so that the white light emitting diode having the same color coordinates is difficult to mass-produce and difficult to control the color temperature due to the glare effect due to color separation.
한편, 공개특허공보 제10-2011-0065161호에는 자연광에 가까운 백색광을 제공하기 위한 엘이디 발광모듈이 개시되어 있다. 도 1은 종래의 엘이디 발광모듈에 실장된 발광다이오드의 배열 패턴을 나타낸 것이다. 이러한 발광다이오드의 배열 패턴에 따라 나타나는 백색광은 서로 다른 파장을 갖는 발광다이오드로부터 방출되는 빛이 자연스럽게 혼합되지 않고 구분되어 파장 및 색온도 차이에 따른 얼룩이 발생하여 완전한 백색광을 구현하기 어렵다.On the other hand, Korean Patent Publication No. 10-2011-0065161 discloses an LED light emitting module for providing white light close to natural light. 1 illustrates an arrangement pattern of a light emitting diode mounted in a conventional LED light emitting module. The white light appearing according to the array pattern of the light emitting diodes is not naturally mixed without the light emitted from the light emitting diodes having different wavelengths, so that staining occurs due to the difference in wavelength and color temperature, and thus it is difficult to realize perfect white light.
