摘　　要：旅游洞穴景观照明光源的选择是洞穴景观美学展现和景观保护的重要内容。热光源的使用导致洞穴环境温度及景观表面温度增高，使得洞穴景观受到损坏。第四代LED冷光源的应用，是洞穴景观照明光源的一次革命性进步，这种光源环保、节能、光效高、寿命长，经过四川米易县龙潭溶洞灯光改造中的探索，在景点的光照度变化不大的情况下，其表面温度下降了2～3℃，对洞穴旅游资源的保护起到了重要的作用。同时，LED光源的应用，也展示了洞穴景观的独特效果。The selection of lighting sources in show cave is very important for the protection of scenes. The use of thermo-light source in show cave leads to increased temperature to cave environment and the temperature of scenes＇ surface, and the scenes are easy to be damaged. Whereas, the application of fourth-generation LED cool-light source is a revolutionary advance, and it is advantageous for environmental protection, energy saving, high-efficient and long service life. It plays a perfect effect in the protection of scenes and lighting in Longtandong in Miyi county, Sichuan province.
