Abstract

An optoelectronic component includes an optoelectronic semiconductor chip embodied as a volume emitter, wherein the optoelectronic semiconductor chip is embedded into an optically transparent molded body, a soldering contact is arranged at an underside of the molded body, a bonding wire forms an electrically conductive connection between an electrical contact area of the optoelectronic semiconductor chip and the soldering contact, and the bonding wire is embedded into the molded body.

Claims (20)

1. An optoelectronic component comprising an optoelectronic semiconductor chip embodied as a volume emitter,

wherein the optoelectronic semiconductor chip is embedded into an optically transparent molded body,

a soldering contact is arranged at an underside of the molded body,

a bonding wire forms an electrically conductive connection between an electrical contact area of the optoelectronic semiconductor chip and the soldering contact,

the bonding wire is embedded into the molded body,

the molded body has a pyramidal-frustum-shaped section,

a lateral surface of the pyramidal-frustum-shaped section forms a part of the underside of the molded body,

the lateral surface is at least partly covered by the soldering contact,

the underside of the molded body with the soldering contact arranged at the underside of the molded body forms an underside of the optoelectronic component, and

a wavelength converter layer is interposed between the lateral surface of the pyramidal-frustum-shaped section and the soldering contact and between a light emitting surface of the semiconductor chip and the optically transparent molded body, wherein the wavelength converter layer is in contact with a solder stop element in a recess within the soldering contact.

2. The optoelectronic component as claimed in claim 1 , wherein the optoelectronic semiconductor chip is at least partly arranged in the pyramidal-frustum-shaped section.

3. The optoelectronic component as claimed in claim 1 , wherein the soldering contact comprises a material having a reflectivity of at least 75% for a wavelength of a radiation emittable by the optoelectronic semiconductor chip.

4. The optoelectronic component as claimed in claim 1 , wherein the material of the molded body comprises filling particles.

5. The optoelectronic component as claimed in claim 4 , wherein the filling particles comprise amorphous SiO 2 powder.

6. The optoelectronic component as claimed in claim 1 , wherein the material of the molded body comprises converter particles that convert a wavelength of an electromagnetic radiation.

7. The optoelectronic component as claimed in claim 1 , wherein the soldering contact directly contacts the optoelectronic semiconductor chip.

8. The optoelectronic component as claimed in claim 1 , wherein a top side of the optoelectronic semiconductor chip is covered by a top side of the molded body.

9. The optoelectronic component as claimed in claim 1 , wherein two soldering contacts are arranged at the underside of the molded body,

two bonding wires form electrically conductive connections between two electrical contact areas of the optoelectronic semiconductor chip and the two soldering contacts, and

the two bonding wires are embedded into the molded body.
