Title (DE) OPTOELEKTRONISCHES BAUELEMENT UND HINTERGRUNDBELEUCHTUNG FÜR EIN DISPLAY
(EN) OPTOELECTRONIC COMPONENT AND BACKGROUND LIGHTING FOR A DISPLAY
(FR) COMPOSANT OPTOÉLECTRONIQUE ET DISPOSITIF DE RÉTROÉCLAIRAGE POUR UN ÉCRAN
Abstract:
(DE) Die Erfindung betrifft ein optoelektronisches Bauelement (100) aufweisend einen Halbleiterchip (2) zur Erzeugung einer Primärstrahlung im blauen Spektralbereich, ein Konversionselement (4), das im Strahlengang des Halbleiterchips (2) angeordnet ist und zur Erzeugung einer Sekundärstrahlung aus der Primärstrahlung eingerichtet ist, wobei das Konversionselement (4) zumindest einen ersten Leuchtstoff (9) und einen zweiten Leuchtstoff (10) umfasst, wobei der erste Leuchtstoff (9) Sr (Sr1-xCax) Si2AI2N6 :Eu2+ und/oder (Sr1-yCay) [LiAI3N4] :Eu2+ mit 0 ≤ x ≤ 1 und 0 ≤ y ≤ 1 ist, wobei eine aus dem Bauelement (100) austretende Gesamtstrahlung (G) weißes Mischlicht ist.
(EN) The invention relates to an optoelectronic component (100) having a semiconductor chip (2) for producing a primary beam in the blue spectral range, a conversion element (4) which is arranged in the beam path of the semiconductor chip (2) and is designed to produce a secondary beam from the primary beam, wherein the conversion element (4) comprises at least one first fluorescent substance (9) and a second fluorescent substance (10), wherein the first fluorescent substance (9) is Sr (Sr1-xCax) Si2AI2N6 :Eu2+ and/or (Sr1-yCay) [LiAI3N4] :Eu2+ with 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1, wherein a total beam (G) emerging from the component (100) is white mixed light.
(FR) L'invention concerne un composant (100) optoélectronique présentant une puce semiconductrice (2) pour générer un rayonnement primaire dans le domaine spectral bleu, un élément de conversion (4) agencé dans le trajet optique de la puce semiconductrice (2) conçu pour générer un rayonnement secondaire à partir du rayonnement primaire, cet élément de conversion (4) comprenant au moins une première substance luminescente (9) et une deuxième substance luminescente (10), la première substance luminescente (9) étant Sr(Sr1-xCax)Si2Al2N6:Eu2+ et/ou (Sr1-yCay)[LiAl3N4]:Eu2+, étant entendu que 0 ≤ x ≤ 1 et 0 ≤ y ≤ 1. Un rayonnement total (G) sortant du composant (100) est une lumière mixte blanche.
