SELF-CLEANING LIGHTING DEVICE

摘要

A lighting device comprising a source of light and a casing, allowing the passage of at least some of the light generated, which is coated on at least one face with a photocatalytically active layer which in low light conditions is sufficiently active to degrade and reduce organic contamination into easily removable particles which do not adhere to the layer and/or to give to the layer a hydrophilic nature. An independent claim is also included for a method of manufacturing the claimed device in which the photocatalytically active layer is formed by a sol-gel route, by vapor phase deposition thermal or plasma assisted at atmospheric pressure or under vacuum or reduced pressure, especially by cathodic spraying assisted by a magnetic field.
