(2003) reported that red and blue LED blends are helpful for tomato grafting. In Korea, Kim et al. (2008) reported that blue LED inhibited young seedlings growth.

이러한 식물의 흡수피크파장을 이용한 종래기술로 대한민국 등록특허공보 제10-0906226호(공고일자: 2009.07.07)에는 "식물 생장을 촉진하는 온실용 LED 조명장치"가 제안된 바 있다.In Korean Patent Registration No. 10-0906226 (publication date: 2009.07.07), a "green lighting LED lighting device for promoting plant growth" has been proposed in the prior art using the absorption peak wavelength of such plants.

상기의 종래기술은 주 파장이 420~470㎚ 인 청색 LED와, 주 파장이 640~690㎚ 인 적색 LED가 혼합되어 배열되어 있는 광원기판을 이용하는 것을 특징으로 한다.The above-described conventional technique uses a light source substrate in which a blue LED having a main wavelength of 420 to 470 nm and a red LED having a main wavelength of 640 to 690 nm are mixed and arranged.

하지만, 상기의 종래기술은 청색 LED와 별도의 적색 LED를 모두 이용하고 있으나, 식물광합성에 유효한 LED광원 중 660nm 파장 칩을 국내에서 제조하지 않아, 수입에 의존 등기구의 생산단가를 높혀 농업현장의 LED광원 적용을 더디게 하는 문제점이 있었다.However, the above-mentioned conventional technique uses both blue LED and separate red LED, but since the 660nm wavelength chip among the LED light sources effective for plant photosynthesis is not manufactured in domestic, the production cost of the luminaire depending on the import is increased, There was a problem of slowing the application of the light source.

본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 질화물계의 적색형광체를 이용하여 하나의 청색LED칩으로 이루어진 LED패키지에서 식물 생장에 필요한 청색 파장대역의 빛은 물론 적색 파장대역의 빛이 발산되도록 구성한 질화물계의 적색형광체를 이용한 식물 생장용 엘이디 조명 장치를 제공하는 데에 있다.It is an object of the present invention to provide an LED package made of one blue LED chip using a nitride-based red phosphor and capable of emitting light of a blue wavelength band And to provide a plant-growing LED lighting device using a nitride-based red phosphor that is configured to emit light of a red wavelength band as well as light.

상기와 같은 목적을 달성하고자 본 발명에 따른 질화물계의 적색형광체를 이용한 식물 생장용 엘이디 조명 장치는, 450㎚ 파장대역의 빛을 발산하는 청색LED칩과; 실리콘 계열의 몰딩액과 적색형광체가 혼합된 조성물로서 상기 청색LED칩에 도포되는 광변환체를; 포함하되, 상기 적색형광체는 질화물계로서 화학식이 CaAlSiN 3 :Eu 2+ 인 것을 특징으로 한다.According to an aspect of the present invention, there is provided a plant lighting lighting device using a nitride-based red phosphor, comprising: a blue LED chip emitting light in a wavelength band of 450 nm; A composition comprising a silicone-based molding liquid and a red phosphor mixed therein, wherein the light conversion material is applied to the blue LED chip; Wherein the red phosphor is a nitride system and is characterized by the formula CaAlSiN 3 : Eu 2+ .

또한, 본 발명에 따른 질화물계의 적색형광체를 이용한 식물 생장용 엘이디 조명 장치는, 상기 광변환체를 통해 발산되는 빛의 파장대역은 450㎚ 및 670㎚인 것을 특징으로 한다.Further, the LED lighting apparatus using the nitride-based red phosphor according to the present invention is characterized in that the wavelength band of the light emitted through the light converter is 450 nm and 670 nm.

또한, 본 발명에 따른 질화물계의 적색형광체를 이용한 식물 생장용 엘이디 조명 장치는, 상기 광변환체는 상기 실리콘 계열의 몰딩액과 상기 적색형광체가 10:3~7의 중량비로 혼합된 것을 특징으로 한다.Further, in the LED lighting device for plant growth using the nitride-based red phosphor according to the present invention, the silicon-based molding liquid and the red phosphor are mixed in a weight ratio of 10: 3 to 7, do.

FIG. 2 and FIG. 3 are schematic cross- FIG. 5 is a graph showing the relationship between the wavelength and the light intensity according to the mixing ratio of the red phosphors of the LED lighting apparatus for plant growth. FIG.

도 1 내지 도 3을 살펴보면, 본 발명의 일실시예에 따른 질화물계의 적색형광체를 이용한 식물 생장용 엘이디 조명 장치는 청색LED칩(10)과, 광변환체(20)를 포함하여 구성된다.1 to 3, an LED lighting apparatus using a nitride-based red phosphor according to an embodiment of the present invention includes a blue LED chip 10 and a light converter 20.

상기 청색LED칩(10)은 기판(S)에 실장되어 450㎚ 파장대역의 빛을 발산하는 구성이다.The blue LED chip 10 is mounted on the substrate S and emits light of a wavelength band of 450 nm.

상기 청색LED칩(10)은 적색LED칩이 비하여 상대적으로 제조가 용이하여 현재 국내에서 생산이 가능하다는 장점이 있다.The blue LED chip 10 is relatively easy to manufacture as compared with the red LED chip, and thus the blue LED chip 10 can be produced in Korea at present.

상기 광변환체(20)는 상기 청색LED칩(10)을 둘러싸도록 기판(S)에 설치된 중공형의 몰드(M) 내부로 충진되며 상기 청색LED칩(10)을 도포하는 구성이다.The light converter 20 is filled in the hollow mold M provided on the substrate S so as to surround the blue LED chip 10 and applies the blue LED chip 10.

본 발명의 일실시예에서 상기 광변환체(20)는 실리콘 계열의 몰딩액과 적색형광체가 혼합된 조성물로서 상기 적색형광체가 질화물계로서 화학식이 CaAlSiN 3 :Eu 2+ 인 것을 특징으로 한다.In one embodiment of the present invention, the light converter 20 is a composition in which a silicon-based molding liquid and a red phosphor are mixed, and the red phosphor is a nitride system and is represented by the formula CaAlSiN 3 : Eu 2+ .

상기 광변환체(20)에 질화물계 적색형광체(CaAlSiN 3 :Eu 2+ )를 이용하는 경우 450㎚ 파장대역의 빛을 발산하는 상기 청색LED칩(10)을 여기광원으로 하여 450㎚ 파장대역의 빛은 물론 670㎚ 파장대역의 빛을 발산할 수 있는 조명을 제작할 수 있게 되는 것이다.When the nitride-based red phosphor ( CaAlSiN 3 : Eu 2+ ) is used for the light converter 20, the blue LED chip 10 that emits light in the wavelength band of 450 nm is used as an excitation light source, It is possible to manufacture an illumination capable of emitting light of a wavelength band of 670 nm as well.

한편, 본 발명에서 상기 광변환체(20)는 실리콘 계열의 몰딩액과 상기 적색형광체가 일정 중량비로 혼합되어 구성된다.Meanwhile, in the present invention, the light converter 20 is formed by mixing a silicon-based molding liquid and the red phosphor at a constant weight ratio.

도 2의 가로축은 상기 광변환체(20)를 통과한 빛의 파장을 나타낸 것이고, 세로축은 그 빛의 광도를 나타낸 그래프이다.The horizontal axis of FIG. 2 shows the wavelength of the light passing through the light converter 20, and the vertical axis shows the luminance of the light.

도 2를 살펴보면, 실리콘 계열의 몰딩액과 상기 적색형광체의 중량비가 10:3, 10:5 및 10:7로 혼합된 상기 광변환체(20)에서 발산되는 빛의 경우 450㎚ 파장대역의 빛과 650㎚ 파장대역의 빛의 광도가 모두 우수함을 확인할 수 있다.2, in the case of the light emitted from the light converter 20 in which the weight ratio of the silicon-based molding liquid and the red phosphor is 10: 3, 10: 5, and 10: 7, And the light intensity of 650 nm wavelength band is excellent.

한편, 도 3은 일정 중량의 실리콘 계열의 몰딩액에 상기 적색형광체의 투입량을 변화시키며 상기 광변환체(20)를 통과한 빛의 파장과 광도의 관계를 도시한 그래프이다.3 is a graph showing the relationship between the wavelength of light passing through the light converter 20 and the luminous intensity of the silicon phosphor in a molding liquid of a predetermined weight and varying the amount of the red phosphor.

도 3에서 상기 적색형광체의 투입량 5㎎은 실리콘 계열의 몰딩액과 상기 적색형광체의 혼합 중량비가 10:3인 경우이고, 7㎎은 10:5인 경우이며, 9㎎은 10:7인 경우이다.In FIG. 3, the input amount of the red phosphor is 5 mg, the mixing weight ratio of the silicon-based molding liquid and the red phosphor is 10: 3, 7 mg is 10: 5, and 9 mg is 10: 7 .

도 3을 살펴보면, 상기 적색형광체의 투입량 9㎎과 10㎎ 사이에서 적색광 즉, 650㎚ 파장대역의 빛의 조도에 큰 차이를 갖는 것을 알 수 있다.Referring to FIG. 3, it can be seen that there is a large difference in illuminance of red light, that is, light of 650 nm wavelength band, between 9 mg and 10 mg of the amount of the red phosphor.

이는, 실리콘 계열의 몰딩액과 상기 적색형광체의 혼합 중량비가 10:3 미만인 경우 450㎚ 파장대역의 빛의 광도에 대비하여 670㎚ 파장대역의 빛의 광도가 너무 약하게 되는 것을 의미하고, 실리콘 계열의 몰딩액과 상기 적색형광체의 혼합 중량비가 10:7을 초과하는 경우 상기 적색형광체에 의해 손실이 생겨 670㎚ 파장대역의 빛의 광도가 혼합 중량비 10:3일때 광도의 70%로 저하됨으로써 전체적인 광효율이 저하되는 것을 의미한다.This means that when the mixing weight ratio of the silicone-based molding liquid and the red phosphor is less than 10: 3, the light intensity of the 670 nm wavelength band becomes too weak compared to the light intensity of 450 nm wavelength band, When the mixing weight ratio of the molding liquid to the red phosphor is more than 10: 7, loss is caused by the red phosphor and the light intensity of 670 nm wavelength band is reduced to 70% of the light intensity when the mixing weight ratio is 10: 3, It means that it is degraded.

따라서, 본 발명에서는 상기 광변환체(20)는 실리콘 계열의 몰딩액과 상기 적색형광체가 10:3~7의 중량비로 혼합된 것을 특징으로 하게 된 것이다.Accordingly, in the present invention, the light conversion member 20 is characterized in that a silicon-based molding liquid and the red phosphor are mixed at a weight ratio of 10: 3 to 7.

아래의 [표 1]에는 실리콘 계열의 몰딩액(실리콘)과 상기 적색형광체(형광체)의 혼합 비율에 따른 분광 특성을 나타내었다.Table 1 below shows the spectroscopic characteristics according to the mixing ratio of the silicon-based molding liquid (silicon) and the red phosphor (phosphor).

한편, 아래의 [표 2]에는 청색LED칩과 적색LED칩을 각각 별도로 이용한 LED조명(청적 단품)과, 본 발명의 일실시예에 따른 LED조명(청적 1.2, 청적 1.6 및 청적 2.0)의 소비전력, 광량 및 피크파장을 나타내었다.On the other hand, in Table 2 below, the LED lighting (pure single product) using the blue LED chip and the red LED chip separately and the consumption of the LED lighting according to the embodiment of the present invention (clear 1.2, clear 1.6 and clear 2.0) Power, light amount and peak wavelength.

육묘재배 공정 중 광원에 민감한 접목묘 활착 과정에 상기 4종의 조명을 이용하여 생장실험을 진행한 결과 4종의 조명 모두 접목묘 활착에 매우 좋은 특성을 보였다.As a result of the growth experiment using the above four kinds of lights during the germination process sensitive to the light source during the seedling growing process, all four kinds of lights showed very good characteristics for the grafting of grafted seedlings.

한편, 고추 같은 경우는 청색LED칩과 적색LED칩을 각각 별도로 이용한 LED조명(청적 단품)보다 본 발명의 일실시예에 따른 LED 조명(청적 1.2, 청적 1.6 및 청적 2.0)이 묘소질에 더 좋은 결과를 보이기도 하였다.On the other hand, in the case of red pepper, the LED illumination (clear 1.2, clear 1.6 and clear 2.0) according to an embodiment of the present invention is superior to the LED illumination (clear one) using the blue LED chip and the red LED chip separately Respectively.

따라서, 상기 적색형광체의 대량 생산으로 제조단가를 낮춘다면, 현재 수입에 의존하는 660nm 단색광 LED를 이용하는 조명보다 보다 저렴한 식물생장용 LED 조명 장치의 제작이 가능함을 확인할 수 있었고, 본 발명의 일실시예에 따른 질화물계의 적색형광체를 이용한 식물 생장용 엘이디 조명 장치의 경우 접목묘 활착율이 매우 높음을 확인할 수 있었다.Therefore, it can be confirmed that it is possible to manufacture an LED lighting device for plant growth more inexpensively than illumination using 660 nm monochromatic LED, which is dependent on current import, if the manufacturing cost is reduced by mass production of the red phosphor. It was confirmed that the grafting rate of the grafted seedlings was very high in the case of the LED lighting device using the nitride based red phosphor.
