User-Centric Measures of the Perceived Light Qualities of Lighting Products

Nowadays, lighting planning is predominantly determined by the need to meet physically measurable requirements that are often based on current standards. However, meeting minimum technical of standards no guarantee for a visually appealing light environment. Instead, perceived qualities also be included achieve better user comfort. Taking perception-based into consideration when creating environment is, many, not an easy task. In addition, common terminology currently lacking, both in industry and research. The aim this paper therefore, explore how white sources can described employing user-centric measures. focus was colour diffuse distinct since these have great impact visual impression light. perception assessed applying analytical sensory analysis products, method found promising previous work. methodology measurement human senses, which particularly valuable developing general terminology. Since still quite new topic lighting, applicability using assess real context investigated. results studies showed further concepts addition those used. For colour, reddish, bluish, yellowish, greenish colours proved suitable providing richer description quality. satisfactorily captured variations contrast produced shadows, reflections, sparkles. revealed applicable assessing real-world context. latter means knowledge gained laboratory translated environments. measures investigated contributed related qualities. These complement physical promote environments only energy efficient requirements, but cater increased Doi: 10.28991/ESJ-2023-07-02-022 Full Text: PDF
