LIGHT CONVERTING DEVICE HAVING A WAVELENGTH CONVERTING LAYER WITH A HYDROPHOBIC NANOSTRUCTURE
(FR)
DISPOSITIF DE CONVERSION DE LUMIÈRE POSSÉDANT UNE COUCHE DE CONVERSION DE LONGUEUR D'ONDE AVEC UNE NANOSTRUCTURE HYDROPHOBE
Abstract:
(EN)
The present invention relates to a light converting device (11) comprising a solid state light source (2) and a wavelength converting layer (3) arranged to at least partly wavelength convert the light emitted, in use, by the solid state light source (2), the wavelength converting layer (3) having a back side (4) facing the solid state light source (2) and a front side (5) opposite the back side (4), wherein the front side (5) of the wavelength converting layer (3) defines an exit window of the light converting device (11). The light converting device (11) further comprises a hydrophobic nanostructure (6) having spaced apart protrusions (66) arranged on the front side (5) of the wavelength converting layer (3) and a protective coating (7) applied on top of the hydrophobic nanostructure (6).
(FR)
La présente invention concerne un dispositif de conversion de lumière (11) comprenant une source de lumière à semi-conducteur (2) et une couche de conversion de longueur d'onde (3) conçue pour convertir au moins partiellement la lumière émise, lors de l'utilisation, par la source de lumière à semi-conducteur (2), la couche de conversion de longueur d'onde (3) présentant un côté arrière (4) orienté vers la source de lumière à semi-conducteur (2) et un côté avant (5) opposé au côté arrière (4), le côté avant (5) de la couche de conversion de longueur d'onde (3) définissant une fenêtre de sortie du dispositif de conversion de lumière (11). Le dispositif de conversion de lumière (11) comprend en outre une nanostructure hydrophobe (6) possédant des saillies espacées (66) agencées sur le côté avant (5) de la couche de conversion de longueur d'onde (3) et un revêtement protecteur (7) appliqué au-dessus de la nanostructure hydrophobe (6).
