METHOD AND DEVICE FOR LIGHTING SPACE, INTENDED FOR STAYING AND / OR MOVING PERSONS AND VEHICLES, ESPECIALLY IN ROAD TUNNELS

摘要

The method of illumination with a predetermined ambient light (11, 12) intended for the stay and / or passage of people and / or vehicles includes the steps of selecting and installing in the environment (11, 12) at least one passive lighting element (13 ) containing a photoluminescent pigment, as a rule, a material with the formula AlSrCaOEu, Dy and / or an alkaline-earth metal aluminate doped with europium and / or dysprosium, in particular, with the formula SrAlOEu, Dy or SrAlOEu, Dy, B, suitable for emitting photoluminescent, suitable for emitting a photoluminescent, Dy, or SrAlOEu, Dy, B, suitable for emitting photoluminescent, suitable for emitting photoluminescent, Dy, or SrAlOEu, Dy, B, suitable for emitting photoluminescent, suitable for emitting photoluminescent, Dy, or SrAlOEu, Dy, B, suitable for emitting photoluminescent, suitable for emitting photoluminescent, Dy, or SrAlOEu, Dy, B, suitable for emitting photoluminescent, suitable for emitting photoluminescent, Dy, or SrAlOEu, Dy, B a stream (13 ') upon irradiation of the primary luminous flux (19'). In one aspect of the present invention, the environment (11, 12) is provided with at least one active lighting device (19) with the possibility of supplying power or a previously existing electric lighting installation that is adapted to create a primary luminous flux (19 '), and the method provides for the supply of adjustable electricity to at least one active lighting device (19) to create a primary lighting current (19 '), which is added to the photoluminescent current (13'), ensuring that we require u lighting. In accordance with another aspect of the present invention, the method includes the steps of selecting at least one active lighting device (19) such that, when a predetermined power supply is applied, the primary luminous flux (19 ′) and the photoluminescent luminous flux (13 ′) together provide the required amount of illumination . The method significantly reduces the consumption of light energy, as well as the cost of the lighting installation. In an exemplary embodiment, the environment is, for example,
