Lighting, Quality and Artificial Intelligence

Data collected during investigations with lighting equipment using Solid State Lighting -SSL (WLEDi) technology are presented and considered. One focus is on the quality parameters of artificial lighting. Research on road lighting was carried out at the University City Armando de Salles Oliveira (CUASO), Campus of the University of So Paulo -USP and for internal lighting from an experiment at the Institute of Energy and Environment for more than 2,600 hours. The long-term experiment uses different brands of Edison-type WLEDi lamps (E-27) is running under regulated energy, continuously, and ambient temperature. The results obtained show the depreciation of the light output and correlated colour temperature, just as it was obtained for the CUASO road lighting system that has already completed more than 20 kh in service. The results are expected to increase local knowledge about the depreciation of light production by the SSL technology used by Brazilian consumers.
