Visibility and color-rendering properties of light sources in tunnel lighting

摘要：

We carried out the experiments in tunnel where high frequency fluorescent lamps are used and in tunnel where low-pressure sodium lamps are used. As a result, we found that adopting light sources with high color-rendering properties is effective for the visibility of visual objects and the possibility of accurately conceiving the equipments in the tunnel including fire plugs or the body colors of preceding vehicles will become higher.
