이산화탄소는 사람의 활동이 많을수록 농도가 심해지고 1000PPM을 넘어서면 신체에 악영향을 주기도 한다. 보통의 가정에서는 가족이 모이는 저녁시간부터 이산화탄소의 농도가 높아지는데 심할경우 답답함, 호흡곤란등이 올수 있다. 그러나 대기오염과 지구온난화로 인해 환기에도 한계가 있을 수 있다. 그래서 공기청정기, 산소발생기등 실내질향상 관련 기구의 활용이 높아졌는데 경제적 부담이나 저효율성 문제등을 야기하고 있다. 본 발명은 미세조류를 활용한 이산화탄소 저감 조명시스템에 관한 것으로, 보다 상세하게는 기존 조명시스템의 전력을 활용하여 미세조류를 배양하고 미세조류의 뛰어난 산소배출 능력을 통해 이산화탄소를 저감하여 실내공기질 향상시키는데 관한 것이다. 미세조류의 이산화탄소 제거효율이 나무와 식물에 비교하여 최소 25배에서 최대 200배로 실내공기 내 이산화탄소 제거능력이 우수하므로 미세조류 필터 내에 미세조류(클로렐라, 스피룰리나 등)를 배양하고, 필터 내에 실내공기를 CO2 주입 펌프, CO2 조절기, CO2 센서, 공기순환FAN를 통해 공급하여, 실내공기 내 이산화탄소를 미세조류의의 광합성을 통해 높은 효율로 제거하는 것으로 달성된다. 본 발명의 다른 목적은, 조명시스템의 LED 조명�
