Abstract

터널구조물의 특성상 터널조명은 일반 도로의 조명과 달리 주간에도 조명이 필요하므로, 터널 유지관리 비용 가운데 터널조명을 위한 전력요금은 가장 높은 비율을 차지하고 있는 것으로 알려져 있다. 따라서 유지비용 절감 등을 위하여 터널조명을 낮은 소비전력, 장수명 등의 장점이 있는 LED램프로 교체 중에 있다. 본 연구에서는 기존 터널조명이 고압나트륨램프인 10개소 터널을 대상으로 터널조명 광원을 LED램프로 교체 시 효과 분석을 위하여, 광원 교체 전 ‧ 후 터널 조도측정결과 및 1년간의 월별 전력사용량을 조사하였다. 터널조명 광원을 고압나트륨램프에서 LED램프로 교체 후 조도는 27.9~490% 향상되었으나, 터널조명용 전력사용량은 평균 47.1% 감소한 것으로 나타났다.

고압나트륨램프

Low-pressure sodium lamps, high-pressure sodium lamps, and fluorescent lamps are mainly used for tunnel lighting in Rep. of Korea, which accounts for the highest percentage in the tunnel maintenance costs. Therefore, tunnel lights are being replaced by LED lamp that have advantages with respect to low power consumption and sustainability. To analyze the effect of replacement high pressure sodium lamp with LED lamp, illumination and monthly power usage per year have been investigated for 10 tunnels. The usage of LED lamp results in illumination improvement from 27.9% to 490% and power saving around average 47.1%.
