Impact of Street Lighting Level on Floodlights

Abstract

The article presents selected results of research related to the use of outdoor lighting, mainly street lighting, in the design of facility illumination. The indicated subject matter primarily concerns architectural structures that are located in urbanized city spaces and in the strict centers of old cities. It is in these areas that there is usually a significant saturation of historic secular and sacred buildings with significant tourist values. At the same time, the immediate surroundings of the structures are usually wrapped by a dense network of street lighting infrastructure. This illumination can be a major setback in the process of illumination planning. Therefore, it is necessary to take into account the extent of this impact on the planned illumination work, related to the selection, mounting, and direction of illumination equipment. This is related to the distance of the street luminaires from the facade, the height of their installation, the distance of the poles from each other, the power of the street luminaires, and the luminous flux distribution of the luminaires used. The purpose of the work undertaken was to analyze the extent to which outdoor lighting influences the planned illumination of an architectural structure and to explore the possibility of its potential use as a component of illumination. Analytical work was conducted at two levels of detail using advanced graphical computer applications. After general considerations and the derivation of conclusions, an example of illumination of a large sacral building was realized successfully using the element of street lighting as a component of illumination.

Assessment of the Historical Gardens and Buildings Lighting Interaction through Virtual Reality: The Case of Casita de Arriba de El Escorial

“…This approach prevents the evaluation of reciprocal influences and integrations, especially in places such as monumental complexes, where a clear separation between the architecture and the surrounding vegetation areas is impossible. To the best of the authors' knowledge, only one study [60] evaluated the interaction between road and park lighting close to historical buildings, verifying the possibility of using it as an additional component for façade lighting design from both photometrical and energy points of view by using DIALux. In particular, the study evaluated the luminance variations on the façade upon varying the road and park lighting typology, as well as the distance from the façade.…”
