Abstract

Low-pressure sodium lamps, high-pressure sodium lamps and fluorescent lamps etc are mainly used tunnel lighting in Rep. of Korea. Power rates for tunnel lighting are known to account for the highest percentage in the tunnel maintenance costs. Therefore, tunnel lights are being replaced by LED that have advantages such as low power consumption and longevity. To analysis effect of replacement low pressure sodium lamp with LED, illumination and monthly power usage for a year are investigated for 8 tunnels. Power usage for tunnel lighting is decreased by 26.1% to 59.6%, and illumination is increased by 34.1% to 293% replacing low pressure sodium lamp with LED.

국내 터널조명에는 저압나트륨램프, 고압나트륨램프, 형광램프 등이 주요 광원으로 사용되고 있으며, 터널 유지관리 비용 가운데 터널조명을 위한 전력요금은 가장 높은 비율을 차지하고 있는 것으로 알려져 있다. 따라서 터널조명은 낮은 소비전력, 장수명 등의 장점을 갖는 LED로 교체 중에 있다. 본 연구에서는 터널조명 LED 교체에 따른 효과 분석을 위하여 기존 터널조명이 저압나트륨램프인 8개소 터널에 대하여, LED 교체 전 ‧ 후 터널 조도측정결과 및 1년간의 월별 전력사용량을 조사하였으며, 분석결과 터널조명 광원을 저압나트륨램프에서 LED로 교체 후 1년간 터널조명용 전력사용량은 26.1~59.6% 감소하였으며, 조도는 34.1~ 293% 향상된 것으로 나타났다.
