摘要
A method for lighting with a predetermined illuminance an environment (11, 12) intended for the stay and/or for the passage of people and/or vehicles comprises steps of selecting and installing in the environment (11, 12) at least one passive lighting element (13) comprising a photoluminescent pigment, typically a material of formula AlxSryCa(1-y)Oz:Eu, Dy and/or an Europium and/or Dysprosium-doped alkaline-earth aluminate, in particular a material of formula SrAl2O4:Eu, Dy or SrAl2O4:Eu, Dy, B, adapted to emit a photoluminescent light flux (13') when exposed to a primary light flux (19'). In an aspect of the invention, the environment (11, 12) has at least one electrically suppliable active lighting body (19) or a pre-existing electric lighting installation, which is adapted to generate the primary light flux (19'), and the method provides supplying an adjusted electric power to at least one active lighting body (19) to generate the primary light flux (19') that is summed to the photoluminescent flux (13'), producing the required illuminance. According to another aspect of the invention, the method provides steps of selecting the at least one active lighting body (19) in such a way that, by supplying it with a predetermined electric power, the primary light flux (19') and the luminescent light flux (13') produce together the required illuminance value. The method remarkably reduces the lighting energy consumptions as well as the costs of the lighting installation. In an exemplary embodiment, the environment is a road or motorway environment (11, 12), for example a or pedestrian road tunnel (11). The passive lighting element (13) can be a photoluminescent stripe (13) arranged on the wall (10, 10') and parallel to the ground (9), having a predetermined width (H).
