To form a housing, the leadframe is sheathed, preferably, with a molding compound, with the thermal connecting part being embedded such that it can be thermally connected from the outside.
CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation of copending International Application No. PCT/DE02/01306, filed Apr. 9, 2002, which designated the United States and was not published in English.
BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The invention relates to a leadframe for a radiation-emitting component, preferably, a light-emitting diode component, to A housing for light-emitting components, preferably, light-emitting diodes, to a radiation-emitting component having a radiation-emitting chip, and to a method for producing the component.
SUMMARY OF THE INVENTION It is accordingly an object of the invention to provide a leadframe and housing for a radiation-emitting component, a radiation-emitting component, and a method for producing the component that overcome the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that provides improved heat dissipation that, in particular, allows high optical power levels to be produced in the component, for radiation-emitting components, and specifies a production method for such a purpose.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1A is a fragmentary plan view a first exemplary embodiment of a leadframe according to the invention;
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the figures of the drawings in detail and first, particularly to FIG. 1 thereof, there is shown a leadframe 2 having a mount part, which is subdivided into two electrical connecting parts 12 a, 12 b, and a thermal connecting part 4. The two electrical connecting parts 12 a, 12 b end in a respective solder connecting strip 3 a, 3 b. One electrical connecting part 12 a has an opening in the form of an eye. The thermal connecting part 4 is linked into the eye opening. For such a purpose, by way of example, the thermal connecting part 4 may be inserted with an accurate fitting into the eye opening in the electrical connecting part 12 a, after which it is crimped to the electrical connecting part 12 a in the form of a rivet. Alternative connections on the circumference between the thermal connecting part 4 and the electrical connecting part 12 a, for example, by riveting, soldering, or welding, likewise are possible.
