ABSTRACT:
A light-emitting semi-conductor diode comprising a light emitting chip at least partially surrounded by a transparent electronics protecting body on which a composite layer foil is disposed, the composite layer foil includes at its side facing away from the electronics protection body a carrier layer, which has a refraction index that is greater than the refraction index of the electronics protection body and, at the opposite side, an active layer of the same material of which the electronics protecting body consists.
