Resumen
En este trabajo primero se analizan los antecedentes respecto de la discusión sobre cuáles métricas representan mejor la percepción de brillo del espacio iluminado, así como sus limitaciones y los desafíos que plantea esta búsqueda. Se realizó un experimento piloto en un espacio iluminado real a fin de comparar las métricas existentes y su relación con la respuesta subjetiva de los observadores. Se midieron iluminancia horizontal y luminancia y, se calculó MRSE-Mean Room Surface Exitance-. Los datos de flujo luminoso y el tipo de distribución de intensidades fueron provistos por el fabricante. Este primer experimento piloto arroja algunos resultados: MRSE, el flujo luminoso y la luminancia parecen ser buenos candidatos para representar la percepción del espacio iluminado, además el tipo de distribución y en mucho menor grado la temperatura de color son variables significativas. La iluminancia horizontal no representaría la respuesta perceptual respecto del ambiente iluminado. Estos resultados ayudan a comprender la necesidad de investigar nuevas métricas y procedimientos que permitan a los diseñadores proyectar y evaluar espacios iluminados teniendo como objetivo la percepción de los usuarios.
In this paper we first analyze the background of the discussion of which metrics best represent the brightness perception of the illuminated space, as well as its limitations and the challenges that this search presents. A pilot experiment was conducted in a real illuminated space in order to compare the existing metrics and their relationship with the subjective response of the observers. Horizontal illuminance and luminance were measured and, MRSE-Mean Room Surface Exitance- was calculated. The luminous flux data and the intensity distribution type were provided by the manufacturer. This first pilot experiment yields some interesting results: MRSE, luminance and luminous flux seem to be good candidates to represent the perception of the illuminated space, besides the type of distribution and to a much lesser degree the color temperature are significant variables. The horizontal illuminance seems to be not represent the perceptual response of the luminous space. These results helped to understand the need to investigate new metrics and procedures that allow designers to project and evaluate illuminated spaces in order to achieve a visually well-qualified space.
