The Importance of Optimal Design in Outdoor Light Source Positioning

In this work we underline the importance of the optimal design for outdoor light systems such that light posts and sources are placed correctly. We present a case study where we considered a city road section equipped with LED sources. On this section, we measured technical luminous coefficients, which were then compared with values listed in standard and normative documentation. Based on this we did a new design that had to follow certain requirements on street and lighting post configuration. Comparing the two designs we conclude that, to have an optimal street light system, the engineer must aim for the best possible design and consider this when deciding on the position of the light sources
