Disinfecting device having improved efficiency and safety

Abstract

The present invention relates to a disinfecting device (1) comprising at least one light source (2) arranged for, in operation, to emit a first light having a first UV wavelength range. The disinfecting device (1) further comprises at least one optical element (7) arranged to collimate a part of the first light emitted from the light source (2) towards at least one louver (3). The at least one louver (3) comprises a plurality of light absorbing structures (4) having a first surface (4′) and a second surface (4′) being opposite to the first surface (4′), the light absorbing structure (4) further having a proximal end (5) being arranged adjacent to the at least one light source, and a distal end (6) being arranged opposite to the proximal end (5). The light absorbing structure (4) has a longitudinal extension L between the proximal end (5) and the distal end (6), and a transversal extension (D) being substantially perpendicular to the longitudinal extension (L). The light absorbing structure (4) is arranged for absorbing a first portion of the first light. The plurality of light absorbing structures (4) also comprises at least one light converting element (8) arranged for converting a second portion of the first light into a second light having a second wavelength range comprising longer wavelengths than the first UV wavelength range. A third portion of the first light is exiting the disinfection device.
