Light-emitting diode arrangement comprising a reflector
First Claim
1. A light diode arrangement with a reflector, comprising a sub-mount on which a light-emitting diode chip is mounted, and a reflector aligned at the sub-mount, said sub-mount comprising a reflector surface located in a beam path of the light-emitting diode chip, wherein the sub-mount comprises a blind hole into which the light-emitting diode chip is inserted and which comprises a paraboloidal reflector surface disposed above the blind hole, said reflector surface having one of a focal point and focal line a center of a surface of the light-emitting diode chip is located, the reflector is formed by a solid body formed of a transparent material and comprising a small irradiation surface opposing the light-emitting diode chip and a large radiation surface opposing same at a distance, between which a lateral surface forming the reflector surface extends, and that the sub-mount comprises an opening above the blind hole into which the reflector body is inserted with the irradiation surface first so that its reflector surface forms a continuation of the reflector surface of the sub-mount.

Abstract
A light-emitting diode arrangement comprises a sub-mount on which a light-emitting diode chip is mounted, and a reflector which is adjusted at the sub-mount and has a reflector surface located in the beam path of the light-emitting diode chip. The reflector is formed from the lateral wall of a solid body consisting of a transparent material and having a small irradiation surface located opposite the light-emitting diode chip (3) and a large radiation surface which is located opposite the same, at a distance, a lateral wall forming a reflector surface extending therebetween, and the sub-mount comprises an opening into which the reflector body is inserted, with the irradiation surface first.
