It is about how to calculate.

발광 다이오드를 포함하는 조명 장치는 소비전력이 적고, 수명이 길며, 협소한 공간에 설치 가능하고, 또한 진공에 강한 특성을 제공한다. The lighting device including the light emitting diode has a low power consumption, a long life, can be installed in a narrow space, and provides a vacuum-resistant characteristic.

최근 눈부신 반도체 기술의 발달로 LED의 수명 및 효율은 점차 높아지고 있으며, 곧 기존의 조명기구들을 대체하게 될 것으로 전망된다.Recently, the lifespan and efficiency of LEDs are gradually increasing due to the development of brilliant semiconductor technology, and it is expected to replace the existing lighting fixtures soon.

긴 수명을 가지는 LED 조명은 유지보수가 어려운 환경에서 사용되는 기존의 조명기구를 가장 빠른 시일 내에 대체하게 될 것으로 예견되며, 높은 연색지수 및 좁은 영역에 빛을 접속하는 것도 가능하여, 상가에서 상품전시를 위한 조명으로 널리 활용되고 있으며, 적은 소비전력으로 인하여 점차 모든 가정의 조명기구들을 대체하는 미래의 에너지 위기를 해결하기 위한 첨병으로 활약할 것으로 기대된다. 또한, 이러한 LED 조명은 집어등으로도 사용될 수 있어, 어선이 더 이상 발전기 및 연료를 싣고 다니지 않아도 되어 선박의 연료 절감에도 크게 기여하게 될 것으로 전망되어 21세기의 화두인 그린에너지 분야에서 반드시 실용화해야 될 기술이다.Long life LED lighting is expected to replace existing luminaires used in difficult maintenance environment at the earliest possible time, and it is also possible to connect the light to a high color rendering index and a small area, so that it can be displayed at the mall. It is widely used as a light source for lighting and is expected to serve as a solution to solve the future energy crisis that gradually replaces all home lighting fixtures due to the low power consumption.

Technology.

LED를 이용한 백색광을 구현하는 방식에는, UV LED 또는 청색 LED에 형광체를 도포하여 패키지 레벨에서 백색광을 구현하는 방법과, 적색, 청색 및 녹색 소자를 인접하게 설치함으로써, 각 LED로부터의 발광이 혼색되어 백색광을 구현하는 방식이 있다.In the method of implementing white light using the LED, a method of realizing white light at the package level by applying a phosphor to a UV LED or a blue LED and installing red, blue, and green elements adjacent to each other, the light emission from each LED is mixed. There is a way to implement white light.

특히, 삼색 LED 방식은 각 발광 소자들 간의 상이한 광학적 특성으로 인하여 균일한 혼색 즉, 자연광에 가까운 백색광이 구현되지 못하는 문제점이 있어 조명등의 설계에 있어 많은 기술적인 어려움이 따른다.In particular, the three-color LED method has a problem in that uniform color mixing, that is, white light close to natural light, is not realized due to different optical characteristics between respective light emitting devices, which causes a lot of technical difficulties in designing a lighting lamp.

나아가, 현재의 조명은 단순히 사물을 보기 위한 역할만 하는 조명에서 벗어나 인간의 감성을 자극하는 감성조명의 시대로 흘러가고 있다. 인간은 우리가 알게 모르게 빛의 색온도에 따라 상당히 민감한 반응을 일으키는데, 이러한 빛의 색온도에 따른 심리적 반응을 이용하는 조명을 감성 조명이라고 한다. Furthermore, the current lighting is moving away from the lighting that merely serves to see objects and into the era of emotional lighting that stimulates human emotion. Humans do not know our response to the color temperature of the light is very sensitive, the light that uses the psychological response to the color temperature of light is called emotional lighting.

The texture may vary.

즉, LED 조명 빛의 색온도 또는 밝기에 따라 사람마다 느끼는 감성이 다를 수 있다. That is, the sensitivity of each person may vary depending on the color temperature or brightness of the LED light.

따라서, 복수개의 LED를 이용하여 하나의 조명등을 구성하고, 이 조명등으로 자연광에 가까운 즉, 높은 CRI를 가지면서, 사용자가 원하는 분위기를 자유롭고 용이하게 연출할 수 있도록, LED 조명의 색온도 및 밝기를 제어하기 위한 LED 색값 산출방법이 절실히 요구되고 있다.

도 1에서, 감성조명을 구현하기 위한 복수개의 LED의 혼합색값을 산출하기 위해, 먼저, 다양한 감성조명을 구현하기 위한 적어도 하나의 색온도를 선정한다(S100). In FIG. 1, in order to calculate mixed color values of a plurality of LEDs for implementing emotional lighting, first, at least one color temperature for implementing various emotional lights is selected (S100).

색온도는 흑체 궤적을 따라 넓은 범위에 걸쳐 분포되어 있지만 이를 모두 재현할 필요는 없으며, 따라서 우리가 일상생활에서 가장 많이 접하는 빛의 종류만 선별하여 재현하면, 보통의 일광을 표현하는데 아무런 문제가 없다. 일 실시예에서, 색온도는 하기 표 1의 선정이유로 15단계로 선정될 수 있다.
The color temperature is distributed over a wide range along the blackbody trajectory, but it is not necessary to reproduce all of them, so if we select and reproduce only the kind of light that we encounter most in everyday life, there is no problem in expressing normal daylight. In one embodiment, the color temperature may be selected in 15 steps due to the selection of Table 1 below.

색온도가 선정되면, 색온도의 구간 범위를 설정한다(S110). 색온도 구간 범위란, 사람의 시각적으로 동일한 색온도로 인지되는 범위를 말하며, 일 실시예에서, 색온도 구간 범위(ΔT)는 “ANSI C78.377-2008”에서 규정한 바와 같이 하기의 수학식 1에 의해 구할 수도 있으나, 같은 색온도 그룹 내에 있더라도 색온도의 구간 범위가 넓어 사람이 인지하기에 따라서는 다른 빛으로 보일 수 있기 때문에 바람직하지 못하다. 따라서, 색온도의 구간 범위(ΔT)는 맥아담 편차타원 범위를 줄여 색온도 구분을 명확히 하기 위해 하기 수학식 2에 의하는 것이 바람직하다. When the color temperature is selected, the section range of the color temperature is set (S110). The color temperature section range refers to a range visually recognized by the same color temperature of a person. In one embodiment, the color temperature section range ΔT is defined by Equation 1 below as defined in "ANSI C78.377-2008". Although it can be obtained, even if it is in the same color temperature group, it is not preferable because the range of the color temperature is wide and may be seen as different light depending on the human perception. Therefore, it is preferable that the interval range ΔT of the color temperature is defined by the following Equation 2 in order to clarify the color temperature division by reducing the McAdam deviation elliptic range.

[수학식 1][Equation 1]

ΔT = 0.0000108×T2 +0.0262×T +8
ΔT = 0.0000108 × T 2 + 0.0262 × T +8

복수개의 LED 각각의 미리 설정된 밝기 단계별 조도값에 색값이 부여되면, 상기 색값을 서로 조합하여 복수개의 LED의 혼합색값을 생성한다(S130).When a color value is given to a predetermined illuminance value for each brightness level of each of the plurality of LEDs, the color values are combined with each other to generate a mixed color value of the plurality of LEDs (S130).

여기서, 혼합색값의 생성은 적색, 녹색, 청색 및 백색의 LED를 이용하는 경우, 각각 LED의 밝기 단계별 조도값을 헥사값으로 변환하여 생성하는 것이 바람직하다.Here, in the case of using the red, green, blue, and white LEDs, the mixed color values are preferably generated by converting illuminance values of the LEDs into hex values.

일 실시예에서, 복수개의 LED 각각의 밝기 스텝을 27 스텝으로 하는 경우로 하는 경우, 조합되는 혼합색값은 27 x 27 x 27 x 27 = 531,441이므로 531,441개가 생성 될 수 있다.In an embodiment, when the brightness step of each of the plurality of LEDs is set to 27 steps, the combined color values to be combined are 27 x 27 x 27 x 27 = 531,441, so that 531,441 can be generated.

혼합색값이 생성되면, 혼합색값에 대한 조명특성을 시험한 후, 생성된 혼합색값의 조명특성이 CIE 색도도의 흑체궤적에 포함되는 혼합색값을 추출하여, 선정된 색온도 구간 범위별로 분류한다(S140). 이는 조명을 구현하는 혼합색값이 흑체궤적에 가까울수록 이상적인 조명특성을 가지기 때문이다.When the mixed color value is generated, the lighting characteristics of the mixed color values are tested, and the mixed color values of the generated mixed color values included in the black body trajectory of the CIE chromaticity diagram are extracted and classified by the selected color temperature section (S140). ). This is because the mixed color value that realizes lighting has an ideal lighting characteristic as it approaches the blackbody trajectory.

색온도 구간별로 흑체궤적에 포함되는 혼합색값들이 분류되면, 분류된 혼합색값 중 맥아담 편차타원의 중심점(10)과 가장 근접한 색좌표 특성을 나타내는 혼합색값을 대표 혼합색값으로 선정한다(S150).
When the mixed color values included in the blackbody trajectory are classified for each color temperature section, the mixed color value representing the color coordinate characteristic closest to the center point 10 of the McAdam deviation ellipse among the classified mixed color values is selected as the representative mixed color value (S150).

하기 표4는 일 실시예에 따른 선정된 대표 혼합색값의 조명 특성을 나타낸다.Table 4 below shows illumination characteristics of selected representative mixed color values according to an embodiment.

다시 도 1에서, 대표 혼합색값이 선정되면, 상기에서 구축된 미리 설정된 밝기 단계별 색값 데이터베이스(표3)를 이용하여, 청색 LED를 기준으로 한 상기 색온도별 대표 혼합색값의 조도비를 산출한다(S160).Referring back to FIG. 1, when the representative mixed color value is selected, the illuminance ratio of the representative mixed color value for each color temperature is calculated based on the blue LED by using the color value database (Table 3) established in the above-described brightness level (S160). .

여기서, 조도가 가장 낮은 청색 LED를 기준으로 조도비를 산출하였으나, 다른 실시예에 따르면, 적색, 녹색 또는 백색 LED를 기준으로 조도비를 산출할 수도 있다.Here, although the illuminance ratio is calculated based on the blue LED having the lowest illuminance, according to another embodiment, the illuminance ratio may be calculated based on the red, green, or white LED.

색온도별 대표 혼합색값의 조도비가 산출되면, 대표 혼합색값의 조도비를 기초로, 미리 설정된 조도단계별 조도를 미리 설정된 밝기 단계별 색값 데이터베이스(표3)에 대입하여 색온도별 조도 단계에 따르는 혼합색값을 재산출한다(S170). 예를 들면, 복수개의 LED의 혼합광의 조도를 색온도별로 20 lx부터 5 lx씩 15단계로 조절이 가능하도록 하려면, 20 lx부터 5 lx씩 증가하는 조도값 15개가 설정될 수 있다. 여기서, 설정된 조도값에 대응하는 혼합색값은 미리 설정된 밝기 단계별 색값 데이터베이스(표3)와 상기 대표 혼합색값의 조도비를 이용하여 산출 할 수 있다.Once the illuminance ratios of the representative mixed color values for each color temperature are calculated, the mixed color values according to the illuminance steps for each color temperature are recalculated by substituting the illuminance for each of the illuminance steps based on the illuminance ratios of the representative mixed color values into the preset color value database for each brightness level (Table 3). (S170). For example, in order to adjust the illuminance of the mixed light of the plurality of LEDs in 15 steps by 20 lx to 5 lx for each color temperature, 15 illuminance values increasing by 20 lx to 5 lx may be set. Here, the mixed color value corresponding to the set illuminance value may be calculated using a preset brightness level color value database (Table 3) and the illuminance ratio of the representative mixed color value.

이는 도 3에 도시된 바와 같이 적색, 녹색, 청색 및 백색 LED의 조도값은 혼합광의 미리 설정된 조도 단계별로 일정한 값을 가지고, 선형으로 증가하는 관계를 이용한 것이다. As shown in FIG. 3, the illuminance values of the red, green, blue, and white LEDs have a constant value according to a predetermined illuminance level of the mixed light and increase linearly.

결과적으로, 이와 같은 방법으로 각 색온도별로 동일한 색온도를 가지면서 밝기만 다른 혼합광을 발생하는 조명을 구현하기 위한 복수개의 LED의 혼합색값을 산출할 수 있다.As a result, it is possible to calculate the mixed color values of the plurality of LEDs for realizing the illumination having the same color temperature for each color temperature and generating mixed light having only different brightness.

여기서, 감성조명 구현을 위한 복수개의 LED의 혼합색값 산출방법은 상기 미리 설정된 혼합광의 조도 단계별 혼합색값의 조명특성을 재산출 하고(S180), 상기 재산출된 혼합색값의 조명특성이 상기 색온도별 구간 범위를 벗어나는지 여부를 검증하며(S190), 상기 재산출된 혼합색값의 조명특성이 상기 색온도별 구간 범위를 벗어나는 경우, 상기 혼합색값이 상기 해당 색온도별 구간 범위 안으로 포함되도록 상기 복수개의 LED의 대표 혼합색값을 재선정(S200)하는 것이 더욱 바람직하다.Here, the method of calculating the mixed color value of the plurality of LEDs for the implementation of the emotional lighting is to recalculate the illumination characteristics of the mixed color value according to the illumination intensity of the preset mixed light (S180), the illumination characteristics of the recalculated mixed color value is the interval for each color temperature In operation S190, if the illumination characteristic of the recalculated mixed color value is out of the range for each color temperature, the representative of the plurality of LEDs is included in the range for each color temperature. It is more preferable to reselect the mixed color values (S200).

하기 표 6은 일 실시예에 따른 색온도별 재산출된 혼합색값 및 개별 LED의 조도를 나타낸다. 표 6에 의하면, 복수개의 LED를 이용한 조명장치는 재산출된 색온도별 밝기단계에 따른 복수개의 LED의 혼합광의 혼합색값 을 바탕으로 사용자의 설정에 따른 색온도 및 밝기의 감성조명을 구현할 수 있게 된다.
Table 6 below shows the recalculated mixed color values for respective color temperatures and illuminance of individual LEDs according to one embodiment. According to Table 6, the lighting apparatus using a plurality of LEDs can realize the sensitivity lighting of the color temperature and brightness according to the user's setting based on the mixed color value of the mixed light of the plurality of LEDs according to the brightness step for each color temperature.
