Abstract: front page image
(EN) Disclosed is an approach to implement a light emitting device with remote wavelength conversion. Lighting arrangements are disclosed which provides consistent color despite inconsistent light path lengths for phosphor light conversions. A component for an LED lighting arrangement, comprises wavelength conversion component that is operable to emit light of a second wavelength range when excited by light of the first wavelength range from at least one LED, wherein emitted light comprises combined light from both the at least one LED and the wavelength conversion component, and in which differing amounts of photoluminescent materials are present at different portions of the wavelength conversion component, wherein a visibly uniform color of light is producible based at least in part on the differing amount of photoluminescent materials at different portions of the wavelength conversion component.
(FR) La présente invention concerne une approche permettant la mise en œuvre d'un dispositif électroluminescent avec conversion de longueur d'onde à distance. L'invention concerne des agencements d'éclairage fournissant des couleurs cohérentes malgré des longueurs de chemin lumineux non cohérentes pour des conversions de lumière au phosphore.
