Figure 5.5 Product and Dialux calculations (illuminances) for option A contemplating the surroundings. The main goal when this one comes into play is to make the light of the railings disappear allowing the user to perceive the darkness and the surroundings. (Fig. 5.3 and 5.4)

The following virtual tests were implemented using different photometries (real IES files from manufacturers) and with different distances. Since it is a historical fence made of steel, the luminaires cannot be integrated into the handrail. Therefore, they are placed in the upper frame of the grill.

Option A. LED strip with assymetric optics

In the horizontal plane, this light solution gives uniformity to the space in both axis (length and width) of the raised path, but at the same time there is a brightly lit area close to the edges, this creates a sharper transition between light and darkness in the middle of the path.

The E max gets to 100lx (nearest to the fence) and gets the E min gets to 4lx (by the middle where the green area and the path meet). This solution is characterized by being the one that gets the most illuminance in the path. As for the vertical plane, the light makes the textures in this plane stand out. This beneficial for the project since the light reflected in the fence is al-
