Title
(DE) WEISS EMITTIERENDE BELEUCHTUNGSEINHEIT AUF LED-BASIS
(EN) LED-BASED WHITE-LIGHT EMITTING LIGHTING UNIT
(FR) UNITE D"ECLAIRAGE EMETTANT UNE LUMIERE BLANCHE, A BASE D"UNE DIODE ELECTROLUMINESCENTE
Abstract
(DE)
Eine weiß emittierende Lumineszenz-Konversions-LED verwendet einen Chlorosilikat-Leuchtstoff, der neben Ca und Mg eine Dotierung mit Europium enthält, sowie einen Granat-Leuchtstoff der seltenen Erden, insbesondere Y und/oder Tb. Damit lässt sich eine hohe Farbwiedergabe erzielen sowie eine hohe Konstanz der lichttecknischen Eigenschaften unter unterschiedlichen Temperaturverhältnissen.
(EN)
The inventive white-light emitting luminescent conversion LED uses a chlorosilicate luminous substance which is doped with europium in addition to containing Ca and Mg and a garnet rare-earth substance, especially Y and/or Tb. This results in high quality colour reproduction and highly constant lighting properties at various temperatures.
(FR)
L"invention concerne une diode électroluminescente à conversion, émettant une lumière blanche, qui utilise une substance luminescente de chlorosilicate contenant, outre du Ca et du Mg, un dopage à l"europium, ainsi qu"une substance luminescente à grenat, constituée de terres rares, notamment de Y et/ou Tb. On obtient ainsi un bon rendu des couleurs et une constance élevée des propriétés d"éclairage dans différentes conditions de température.
