Abstract：
Considering that the energy-storing self-illuminated multi-functional coating material would enhance the brightness inside a tunnel and the illumination uniformity of the road pavement, as well as improve visual comfort inside the tunnel, a test model was established to quantitatively analyze this material′s auxiliary lighting effects.The increase rate of brightness, color rendering index (CRI) and light-wave color temperature were tested under different illuminants using an HAAS-2000 high-precision rapid spectroradiometer. The results show that: 1) the increase rate of brightness is more than 25%; 2) its CRI is 3~17 higher than that of the normal material; 3) the deviation ratio of its light-wave color temperature decreases to varying degrees, which helps to improve the visual range of small objects inside the tunnel.
