Abstract

The lights used in tunnel are studied. Comparison and contrast is made on lighting efficiency, energy cost, using life and cost of highpressure sodium lamps and LED lights. Conclusions drawn are as follows: 1) LED light has advantages such as high lighting efficiency, low energy cost and long using life. 2) LED light is superior than highpressure sodium lamp in term of running cost, though the cost of LED light is higher than that of highpressure sodium lamp. 3) Energysaving, lowcarbon and environmentfriendly effect can be reached by using LED lights.

Key words： tunnel lighting; highpressure sodium lamp; LED light; energysaving; analysis; comparison
