본 고안은 출력광의 색을 조정할 수 있는 조절 가능한 조명 장치에 관한 것으로, 특히, 조명의 발광 다이오드 또는 그 유사 구조에 적용가능한 것이다.The present invention relates to an adjustable lighting device that can adjust the color of output light, and in particular, is applicable to light emitting diodes or similar structures of lighting.

발광 다이오드(Light emitting device)는 수명이 길고 체적이 작으며 내진성(耐振性)이 높고 전력 소비량이 낮은 등의 이점이 있기 때문에, 전기 제품 및 다양한 계기의 인디케이팅 램프 또는 광원에 널리 이용되고 있다. 최근, 발광 다이오드가 멀티 컬러 및 고휘도화로 더욱 발전하여, 발광 다이오드의 응용 범위가 대형 옥외 간판 조명 및 교통신호 램프 등까지 전개되었다.Light emitting devices are widely used in electrical appliances and indicator lamps or light sources of various instruments because of their advantages such as long life, small volume, high shock resistance and low power consumption. . In recent years, light emitting diodes have been further developed into multi-color and high brightness, and the application range of light emitting diodes has been developed to large outdoor signage lights and traffic signal lamps.

발광 다이오드는 단색의 유색광, 예를 들어, 적색, 녹색, 청색 등인 경우가 많아 복합색광을 발생시키고자 할 때에, 예를 들어, 백색광을 발생시키고자 할 경우, 적, 녹, 청의 삼색의 발광 칩을 발광소자에 패키징하고 전류를 통하게 하여 백색의 빛을 복합시켜야 하는데, 이때 칩마다 전기 광학 특성이 다르기 때문에 각각의 복합된 광선이 휘도 및 컬러의 번짐 등의 문제를 발생시키는 것이 가장 큰 문제점이다.Light emitting diodes are often monochromatic colored light, for example, red, green, blue, etc., so that when generating complex color light, for example, white light, red, green, and blue light emission The chip is packaged in a light emitting device and the white light must be mixed by passing a current. In this case, since the electro-optical characteristics are different for each chip, it is the biggest problem that each of the combined light rays causes problems such as luminance and color bleeding. .

이에, 본 고안의 고안자는 출력광의 색을 조정할 수 있는 조절 가능한 조명 장치를 제공하기 위해 연구를 거듭한 결과, 본 고안의 조절 가능한 조명 장치를 고안해내는데 이르렀다.Thus, the inventors of the present invention have been researched to provide an adjustable lighting device that can adjust the color of the output light, and came to devise an adjustable lighting device of the present invention.

본 고안의 주된 목적은 출력광의 색을 조정할 수 있어 원하는 광색을 얻을 수 있는 조절 가능한 조명 장치를 제공하는 것이다.The main object of the present invention is to provide an adjustable lighting device that can adjust the color of the output light to obtain the desired light color.

본 고안은 제어 회로 기판, 복수의 발광 다이오드 및 컬러 센서(Color sensor)를 포함하고, 이 복수의 발광 다이오드가 제어 회로 기판에 마련되며, 이 발광 다이오드가 적어도 하나의 적색 칩, 청색 칩 및 녹색 칩으로 이루어지고, 또한 이 제어 회로 기판이 이 컬러 센서에 접속됨으로써, 컬러 센서에 의해 발광 다이오드의 방출광을 검출·조정하여 원하는 색으로 조절하여 안정적인 광색을 유지할 수 있도록 한다.The present invention includes a control circuit board, a plurality of light emitting diodes and a color sensor, the plurality of light emitting diodes are provided on the control circuit board, the light emitting diodes being at least one red chip, blue chip, and green chip. In addition, the control circuit board is connected to the color sensor, whereby the color sensor detects and adjusts the emission light of the light emitting diode to adjust to a desired color so as to maintain a stable light color.

이하, 도면을 참조하면서 실시예를 들어 본 고안을 상세히 설명한다. 이에 의해, 당해 기술분야의 숙련된 당업자이면 간단히 실시할 수 있다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Thereby, it can be performed simply by those skilled in the art.

도 1을 참조하면, 본 고안의 조명 장치(1)는 제어 회로 기판(11), 복수의 발광 다이오드(12) 및 컬러 센서(14)가 마련되고, 이 복수의 발광 다이오드(12)가 제어 회로 기판(11)에 마련되며, 이 발광 다이오드(12)가 도 2에 나타내는 바와 같이, 적어도 하나의 적색 칩(121), 청색 칩(122) 및 녹색 칩(123)으로 이루어진다. 또한, 이 제어 회로 기판(11)이 컬러 센서(14)에 접속되며, 또한 이 제어 회로 기판(11)은 전류 조정 회로(13)와 연결되어 마련될 수 있다.Referring to FIG. 1, the lighting device 1 of the present invention includes a control circuit board 11, a plurality of light emitting diodes 12, and a color sensor 14, and the plurality of light emitting diodes 12 is a control circuit. It is provided in the board | substrate 11, and this light emitting diode 12 consists of at least 1 red chip 121, the blue chip 122, and the green chip 123, as shown in FIG. In addition, the control circuit board 11 may be connected to the color sensor 14, and the control circuit board 11 may be provided in connection with the current adjusting circuit 13.

이 제어 회로 기판(11)이 ＯＮ된 후에 전류 조정 회로(13)의 정류에 의해 원하는 전류를 각 소자에 공급하면, 발광 다이오드(12) 및 컬러 센서(14)가 기동하기 시작하며, 이 발광 다이오드(12)가 적색 칩(121), 청색 칩(122) 및 녹색 칩(123)이 방출하는 3색의 빛을 백색광으로 복합하고, 이 복합된 백색광이 컬러 센서(14)에 의해 검출된다. 이 컬러 센서(14)가 검출한 데이터를 설정된 데이터와 대비하여 검출된 데이터가 설정된 데이터와 합치하지 않으면, 이 전류 조정 회로(13)가 백색 발광 다이오드(12)의 적색 칩(121), 청색 칩(122) 및 녹색 칩(123)이 원하는 전류를 각각 얻도록 전류를 조정한다. 이에 의해, 적색 칩(121), 청색 칩(122) 및 녹색 칩(123)이 적절한 비율의 광을 각각 방출하며, 상기 적절한 비율의 3 종류의 색을 복합함으로써 원하는 광색의 출력을 얻을 수 있다. 따라서, 컬러 센서(14)의 검출 대비로 이들 백색 발광 다이오드(12)가 서로 다른 색의 백색광을 발광하도록 할 수 있어 사용자의 요구를 만족시킬 수 있다.After the control circuit board 11 is turned on, when the desired current is supplied to each element by rectification of the current adjusting circuit 13, the light emitting diode 12 and the color sensor 14 start to start, and the light emitting diode starts. (12) combines the three colors of light emitted from the red chip 121, the blue chip 122 and the green chip 123 into white light, and the combined white light is detected by the color sensor 14. If the data detected by the color sensor 14 does not match with the set data compared with the set data, the current adjustment circuit 13 causes the red chip 121 and the blue chip of the white light emitting diode 12 to be replaced. The current 122 is adjusted so that the 122 and the green chip 123 each obtain a desired current. Thereby, the red chip 121, the blue chip 122, and the green chip 123 emit light of appropriate ratios, respectively, and by combining three kinds of colors of the appropriate ratios, an output of a desired light color can be obtained. Therefore, in contrast to the detection of the color sensor 14, these white light emitting diodes 12 can emit white light of different colors, thereby satisfying the needs of the user.

또한, 이 컬러 센서(14)는 발광 칩(적색 칩(121) , 청색 칩(122) 및 녹색 칩 (123))의 파장도 검출할 수 있고, 각 발광 칩의 발광 파장 및 강도 비율을 적시에 조정하여, 이 설정된 복합광색을 발광 칩의 파장 변화에 따라 바뀌지 않게 하기 때문에, 이 발광 다이오드(12)는 장기간의 사용에도 동일한 광색을 유지할 수 있다.In addition, the color sensor 14 can also detect wavelengths of light emitting chips (red chip 121, blue chip 122, and green chip 123), and timely display the light emission wavelength and intensity ratio of each light emitting chip. Since the set composite light color is adjusted so as not to change with the wavelength change of the light emitting chip, the light emitting diode 12 can maintain the same light color even for long-term use.

상술한 상세한 설명은 본 고안의 실시가능한 실시예에 대한 구체적 설명이나, 상기 실시예는 본 고안의 권리 범위를 제한하는 것은 아니며 본 고안의 기술적 사상을 일탈하지 않는 범위 내에서의 등가 실시 또는 변경은 모두 본 고안의 청구 범위에 포함된다.The above detailed description is a detailed description of an embodiment of the present invention, but the embodiment does not limit the scope of the present invention and equivalent implementation or change within the scope not departing from the technical idea of the present invention. All are included in the claims of the present invention.

이상과 같이, 본 고안은 이하와 같은 효과를 가진다.As mentioned above, this invention has the following effects.

컬러 센서로 발광 다이오드가 방출하는 빛의 파장을 바로 검출하여 검출 결과를 원래의 설정과 비교해 결과가 합치하지 않으면, 전류 조정 회로를 개재하여 전류를 조정하여 원하는 광색을 얻을 수 있다.If the color sensor directly detects the wavelength of light emitted by the light emitting diode and compares the detection result with the original setting, and the results do not match, the desired light color can be obtained by adjusting the current through the current adjustment circuit.
