Patent ID: 8097937

Claim:
A radiation-emitting component, comprising: a radiation-emitting semiconductor chip at least partially sheathed with a radiation-permeable compound; and one of: a leadframe; and a housing for light-emitting components having a leadframe, wherein the leadframe comprises: a mount part having: at least one wire connecting area an opening formed therein and extending completely through the mount part; and at least one external electrical connecting strip; and a separately manufactured thermal connecting part disposed in said opening and fastened into said mount part to form an electrical connection with the at least one external electrical connecting strip, said thermal connecting part having at least one chip mounting area and a reflector well surrounding said chip mounting area, wherein the thermal connecting part extends through the opening in the mount part and connects to the mount part at the opening to transfer heat away from the mount part, wherein said radiation-permeable compound is a plastic compound; and wherein said radiation-permeable compound has a volume described by the formula V≦qH, where H is a height of said chip and q is a scaling factor having a value that is less than 10 mm 2 .
