Beschreibung
Zusammenfassung:	A method and apparatus for improving the optical properties of an LED using a retroreflector element. A light emitting apparatus includes a substrate, at least one light emitting device attached to the substrate and including an outer primary light emitting surface through which substantially all light is emitted, and a retroreflector assembly attached to the substrate. The retroreflector assembly includes a proximal surface adjacent to the substrate, a distal surface spaced away from the substrate, and a retroreflective portion arranged between proximal surface and the distal surface. A distance from the distal surface to the substrate is less than or equal to a distance from the outer primary light emitting surface to the substrate. L'invention concerne un procédé et un appareil pour améliorer les propriétés optiques d'une DEL utilisant un élément rétroréflecteur. Un appareil électroluminescent comprend un substrat, au moins un dispositif électroluminescent fixé au substrat et comprenant une surface d'émission de lumière primaire externe à travers laquelle sensiblement toute la lumière est émise, et un ensemble rétroréflecteur fixé au substrat. L'ensemble rétroréflecteur comprend une surface proximale adjacente au substrat, une surface distale espacée du substrat, et une partie rétroréfléchissante disposée entre la surface proximale et la surface distale. Une distance depuis la surface distale jusqu'au substrat est inférieure ou égale à une distance de la surface d'émission de lumière primaire externe au substrat.
