摘　　要：该文探讨了日光跟踪聚光光纤采光照明系统作为单向隧道出口段补充加强照明的可能性,考虑了目前市场上光纤照明系统的光损失、传输效率及聚光度等技术指标,同时还考虑了隧道所在地区的光气侯条件,建议采用年平均日光光量定量表征采用聚光采光设施的可能性。为了保证单向隧道出口段照明水平在洞口外太阳时隐时现和阴天时正常运营,建议在单向隧道出口段还应采用响应快的LED人工光源作为基本加强照明。This paper discusses the possibility of solar tracking optical fiber lighting system as enhanced light- ing in one-way tunnel exit zone, considers the loss of light, transmission efficiency and concentration ratio of optic fiber lighting system in the market. At the same time, it considers the light climate conditions in the tunnel area, and suggests the possibility of using concentrating lighting facilities can be quantitatively charac- terized by average annual amount of daylight light. In order to ensure the lighting levels in one-way tunnel ex- it zone can operate normally during the cloudy outside of tunnel. And it suggests the fast-response LED should also be used as a basic enhanced lighting in one-way tunnel exit zone.
