Three case studies: Lighting historic public spaces

摘要

The small mediaeval town of Valkenburg aan de Geul in the Dutch province of Limburg is characterized by history, living culture, and modern tourism. The main square is lined with buildings that are centuries old, which are under historical preservation, as well as boutiques, cafes, a river, and, since recently, a newly restored city gate. When it is dark, two pole-mounted lights from ewo provide the atmospheric setting. The poles are constructed from four square tubes with vertical lighting strips mounted between them. Four panels of different sizes, mounted in an offset manner, provide the basic lighting. The distribution and individual orientation of the LED lighting units that are contained in them are adjusted in such a way that even, non-dazzling light reaches every point of the square, regardless of the distance from the poles. Frosted lens optics and a reduced current feed contribute to the desired soft, understated illumination. The separate staging of the surrounding buildings is not affected.
