Abstract

Es wird ein lichtemittierendes Paneel zur Verfügung gestellt, welches eine Mehrzahl von ungehäusten LED-Chips sowie eine Folie aufweist, welche eine Mehrzahl von LED-Chips vor Umwelteinflüssen schützend abdeckt und von diesen abgesandtes Licht mindestens teilweise beeinflusst, beispielsweise frequenzkonvertiert. Die Folie ist eine Konversionsfolie oder eine Diffusorfolie, d.h. sie enthält fluoreszierende Farbstoffe und/oder Diffusoren. Der Fluoreszenzfarbstoff (er wird hier auch Konversionsfarbstoff genannt) und/oder die Diffusoren sind in einen ersten Schichtaufbau eingebettet. Ein zweiter Schichtaufbau ist auf der den lichterzeugenden Elementen zugewandten Seite des ersten Schichtaufbaus angeordnet. Alle Schichten des ersten Schichtaufbaus und alle Schichten des zweiten Schichtaufbaus haben je einen ähnlichen Brechungsindex. Hingegen gibt es einen substantiellen Unterschied zwischen den Brechungsindizes der Schichten des ersten Schichtaufbaus und der Schichten des zweiten Schichtaufbaus, wobei der Brechungsindex der Schichten des ersten Schichtaufbaus klein- beispielsweise kleiner als 1.5, und der Brechungsindex der Schichten des zweiten Schichtaufbaus möglichst gross - beispielsweise grösser als 1.5 - ist. Der Übergang zwischen einer Grenzschicht des ersten Schichtaufbaus und einer Grenzschicht des zweiten Schichtaufbaus ist nicht flach sondern besitzt zur Schichtungsebene einen Winkel bildende oder eventuell gewellte Grenzflächen. Gemäss einem weiteren Aspekt der Erfindung können ungehäuste LED-Chips mit einer sie überziehenden Hülle mit Konversionsfarbstoff versehen sein.
