1 한국동굴학회지, 2009, 95, 15~21 SOLAR-LED * ** *** 2) Dea-Wha, Soh Sang-Tack, Kang Hyun-Jun, Soh Abstract : Global village warming and carbon dioxide CO2 gas, and the human efforts for their healing and necessary alternative technology would be much more difficult things than that of making necessary funds and efforts to lay to sleep angry nature on the earth. The limited natural resources of fossil fuel would be dried up in several decades, and the intensity of diplomatic negotiations for natural resource guarantee among countries may be showed looking alike an war. The drain of fossil fuel called a new word of alternative policy like an environment-friendly green-growth, and the solar-cell and lighting technology for the solar energy applications were developed still more repeatedly day by day from oil lantern to LED high-tech illumination in great economy. Therefore, it was studied that the low-carbon green-growth illumination technology in cave applications with SOLAR-LED system which was produced and unified in connection with solar-cell and LED from the semiconductor production technology, and it was also clarified in necessary with useful cave lighting in heatless and with no photosynthesis of plant production in underground space. Key Words : SOLAR-LED system, low-carbon green-growth, cave lightings :,.,.,,,. SOLAR-LED. : SOLAR-LED,, 1. 서론
