Abstract

This study examined the criteria for efficient LEDs used throughout the experiment of an LED with another light color growth to be used in a plant factory. The experiment was confirmed by measuring the Red-LED, Blue-LED, plant growth, and amount of carbon reduction in a White-LED environment. The white-LED showed a similar growth trend to the Red-LED. Blue-LED showed the lowest growth. Measurements of the carbon dioxide levels, showed that the Red-LED and blue LED produced the lowest levels. The combination of the ratio of the LED showed four Red-LEDs and one blue LED to be the higher of the two. In addition, three Red-LED and one Blue-LED produced equal growth to that of the white-LED. In addition, as much as possible, red is the light color that obtains the result suitable for plant factories.

본 연구는 식물에 대한 LED 광색별 성장을 실험하여 효율적인 식물공장 광원에 대한 기준을 제시하기 위하여 수행되었다. 실험은 Red-LED와 Blue-LED, White-LED 광환경에서 식물의 성장과 이산화탄소 감소를 측정하여 확인하였다. 식물의 성장은 Red-LED에서 성장이 가장 높게 나타났다. White-LED는 Red-LED와 유사한 경향을 보였지만, 시간이 경과 할수록 Red-LED의 성장이 높은 경향을 보였다. Blue-LED는 가장 낮은 성장을 보였다. 그리고 혼합광과 단색광의 광합성정도를 확인한 결과 Red-LED와 Blue-LED를 조합한 광원에서 이산화탄소 감소가 높게 나타났으며 적색광이 많을수록 이산화탄소의 감소도 높게 나타났다. 이와 같은 실험 결과 토대로 혼합광과 백색광에서의 성장을 비교 측정한 결과, 적색 4개, 청색 2개의 비율의 광원에서 식물의 성장이 높게 나타났다. 따라서 식물공장에서 식물의 효율을 높이고 성장을 촉진하기 위해서는 백색의 단색광을 사용하는 것 보다 적색광을 사용하거나, 적색과 청색을 혼합하여 사용하여 파이토크롬 효과를 높이는 것이 바람직하다는 것이 확인되었다. 특히 백색광만 사용하는 경우 성장 초기에는 한해서 사용해야 하며 성장이 잎이 커짐에 따라 적생광이 강한 광을 사용하는 것이 효과적이다.
