Abstract

In this study, the photometry of a wide range of conventional and innovative pavements used in urban and interurban areas was characterised with a laboratory gonioreflectometer, both in new condition and after 30 months of natural ageing. An extreme diversity of behaviour with respect to light reflection has been demonstrated, both over time and between pavements. Various lighting studies have been carried out for cases of renewal of lighting installation with the installation of LED luminaires on poles in place. The calculations have shown that the use of typical CIE r-tables almost systematically leads to non-compliance with the EN 13201 standard, particularly in terms of uniformity. On the other hand, taking into account in the calculations, the photometry of the pavement in its stabilised state makes it possible both to respect the challenges of lighting safety and to achieve significant energy savings. As measurements of pavement photometry are rarely carried out, an alternative is to set up a database of urban pavements, which is one of the achievements of this research.

有没有可能在不考虑路面光度的情况下实现高质量的照明?

在这项研究中，使用实验室角反射计对城市和城际地区广泛使用的传统和创新路面进行了光度测定，包括在新条件下和经过30个月自然老化后。在不同的时间和不同的路面之间，光反射的行为表现出极大的多样性。在灯杆上安装LED灯具的更新照明装置的个案，我们进行了多项照明研究。计算表明，使用典型的CIE r表几乎系统地导致不符合EN 13201标准，特别是在一致性方面。另一方面，考虑到在计算中，路面在稳定状态下的光度测量可以既尊重照明安全的挑战，又实现显著的节能。由于很少进行路面光度测量，因此另一种方法是建立城市路面数据库，这是本研究的成果之一。
