METRICA, l’archivio istituzionale della produzione scientifica dell’Istituto Nazionale di Ricerca Metrologica, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ente.
METRICA utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishThe main goal of this study is to evaluate with objective and subjective investigations how white LED light source affects the perception of visual attributes of coloured materials with different gloss values. The study compares the objective characteristics of a material (colorimetric coordinates and gloss) with the subjective evaluation of associated perceived attributes under compact fluorescent and LED lamps. 21 samples of three different colours (red, blue and green) and seven different gloss finishing were characterized in lab considering the following most substantial optical characteristics: • spectral reflectance in condition 8/d and in the extend range 250-2500 nm, • gloss, • spatial radiance distribution. Then different light sources, LED and compact fluorescent, were selected and used for calculating, from samples measured data, the relevant colorimetric parameters and to test perceived saturation and glossiness using especially designed observation boxes. This paper shows the most interesting results obtained with the Blue colour sample with warm white lights e.g. LED and fluorescent sources.
