Abstract:
1. A semiconductor lamp comprising: a light-emitting semiconductor device comprising a carrier and at least one light-emitting semiconductor component on the carrier, a heatsink having first and second main faces, which are opposite from each other and are formed with respective first and second recesses, an optical element with a main light transmission face, through which radiation emitted from the light-emitting semiconductor device is coupled out, wherein the optical element extends into the first recess of the first main face, and a control unit, wherein the semiconductor device is located adjacent to the first main face, the carrier facing the first main face, wherein the light-emitting semiconductor device is thermally coupled to the heatsink, wherein the heatsink has at least one feedthrough formed in the heatsink for electrical connection of the light-emitting semiconductor device, wherein the control unit is electrically connected to the light-emitting semiconductor device through the feedthrough and in operation supplies a current to the light-emitting semiconductor device, wherein the light-emitting semiconductor device is arranged in the first recess, and wherein the carrier is mounted to a bottom region of the first recess and thermally coupled to the heatsink in the bottom region.
