Abstract:
1. A light emitting semi-conductor diode ( 10 ) comprising at least one light emitting chip ( 50 ) having a light emitting surface ( 51 ), a transparent electronics-protecting body ( 60 ) at least partially surrounding the light emitting chip ( 50 ), a composite layer foil ( 70 ) disposed optically next to and on the electronics-protecting body ( 60 ) so as to at least partially cover it, said composite layer foil ( 70 ) comprising a carrier layer ( 71 ) at its side facing away from the electronics-protection body ( 60 ) which has a refraction index for visible light which is greater than the refraction index for visible light of the electronics-protection body ( 60 ) and said composite layer foil ( 70 ) comprising at its side facing the electronics-protecting body ( 60 ), an active layer ( 72 ) whose base material ( 73 ) consists of the same material as the electronics-protecting body ( 60 ), the active layer ( 72 ) and the carrier layer ( 71 ) having an interface ( 75 ) therebetween, the active layer ( 72 ) is arranged optically next to carrier layer ( 71 ) at interface ( 75 ) without an air gap.
