Descripción
Este documento presenta una metodología propuesta de comparación técnico-económica entre luminarias de montaje horizontal para alumbrado público en las tecnologías de vapor de sodio de alta presión (VSAP) y de estado sólido (LED) empleadas en instalaciones de uso peatonal. En primer lugar, se formula un procedimiento propuesto para determinar la equivalencia entre luminarias de ambas tecnologías, y seleccionar luminarias de tecnología LED como remplazo de luminarias de VSAP. Después, se presenta un caso de estudio en el que se aplica este procedimiento a un escenario real que corresponde a un parque público con áreas de recreación pasiva y circulación exclusiva de peatones. La utilidad del procedimiento se valida mediante cálculos fotométricos realizados con información de luminarias disponibles en el mercado local. Finalmente, se desarrolla un análisis económico del eventual remplazo de las luminarias existentes en el escenario del caso de estudio por luminarias LED seleccionadas a partir del procedimiento propuesto en la primera parte.
This document presents a proposed methodology of technical-economical comparison between streetlight luminaires of horizontal mounting type in High Pressure Sodium (HPS) and Solid State (LED) technologies used in pedestrian lighting systems. First, a proposed procedure to determine equivalence between luminaires of both technologies, and choose LED technology luminaires as replacement of HPS luminaires is formulated. Then, a case study is presented in which the proposed procedure is applied to a real scenario, such as a public park with passive recreation spaces and exclusive pedestrian use. The usefulness of the procedure is validated by means of photometric calculations performed with information of luminaires available in the local lighting market. Finally, an economic analysis of the possible replacement of the existing HPS luminaires in the case study scenario for LED luminaires chosen by means of the initially proposed method is carried out.
