Abstract
(DE)
Es wird eine Beleuchtungseinrichtung (1) zur Hinterleuchtung eines Displays oder eines Fernsehers angegeben. Die Beleuchtungseinrichtung (1) sendet im Betrieb elektromagnetische Strahlung mit einem Gesamtspektrum aus, das einen ersten Peak (6), einen zweiten Peak (9) und einen dritten Peak (10) aufweist, wobei - zumindest die elektromagnetische Strahlung einer der Peaks (6, 9, 10) mittels eines Konversionselements (11) erzeugt ist, und - die Beleuchtungseinrichtung ein Absorbermaterial (12, 12') aufweist, das einen vorgegeben spektralen Bereich des Gesamtspektrums absorbiert. Weiterhin werden ein Display und ein Fernseher angegeben.
(EN)
The invention relates to a lighting device (1) for backlighting a display or a television. In operation, the lighting device (1) emits electromagnetic radiation having a complete spectrum which has a first peak (6), a second peak (9) and a third peak (10), wherein - at least the electromagnetic radiation of one of the peaks (6, 9, 10) is generated by means of a conversion element (11) and - the lighting device has an absorber material (12, 12') which absorbs a specified spectral range of the complete spectrum. The invention further relates to a display and a television.
(FR)
L'invention concerne un dispositif d'éclairage (1) servant à rétroéclairer un écran ou un téléviseur. Le dispositif d'éclairage (1) envoie, lorsqu'il fonctionne, un rayonnement électromagnétique présentant un spectre total comportant un premier pic (6), un deuxième pic (9) et un troisième pic (10). Au moins le rayonnement électromagnétique d'un des pics (6, 9, 10) est produit par un élément de conversion (11). Le dispositif d'éclairage comporte un matériau d'absorption (12, 12'), qui absorbe une plage spectrale prédéfinie du spectre total. L'invention concerne par ailleurs un écran et un téléviseur.
