Title (EN) ELECTROLUMINESCENT DEVICE
(FR) DISPOSITIF ELECTROLUMINESCENT
Abstract:
(EN) An electroluminescent device comprising at least one electroluminescent light source (2) with an electroluminescent layer (21) for emitting a primary radiation with an emission characteristic around a mean emission direction (5), and at least one light-converting element (3) for converting at least part of the primary radiation into a secondary radiation, wherein the shape of the light-converting element (3) is adapted to the emission characteristic of the electroluminescent light source (2) so as to generate a defined correlated color temperature as a function of a viewing angle (10).
(FR) L'invention concerne un dispositif électroluminescent comprenant au moins une source de lumière électroluminescente (2) pourvue d'une couche électroluminescente (21) destinée à l'émission d'un rayonnement primaire avec une caractéristique d'émission autour d'une direction d'émission moyenne (5), et au moins un élément de conversion de lumière (3) élaboré pour convertir au moins une partie du rayonnement primaire en un rayonnement secondaire, la forme dudit élément de conversion de lumière (3) étant adaptée à la caractéristique d'émission de la source de lumière électroluminescente (2), de manière à engendrer une température de couleur corrélée définie en tant que fonction d'un angle de visualisation (10).
