Abstract

A method for manufacturing an optoelectronic component and an optoelectronic component are disclosed. In an embodiment, a method includes applying a conversion layer including a luminescence conversion material to a support plate including a glass, arranging at least two optoelectronic semiconductor chips over the conversion layer on a side remote from the support plate and forming an envelope material free from a luminescence conversion material between the optoelectronic semiconductor chips, thereby forming a workpiece.

Claims (24)

1. An optoelectronic component comprising

at least two optoelectronic semiconductor chips arranged laterally spaced apart from each other;

a conversion layer arranged at upper surfaces of the optoelectronic semiconductor chips; and

a cover plate including a glass,

wherein the conversion layer includes a luminescence conversion material,

wherein the conversion layer is arranged between the optoelectronic semiconductor chips and the cover plate,

wherein all the optoelectronic semiconductor chips of the optoelectronic component are covered by the cover plate, and

wherein lateral surfaces of the optoelectronic semiconductor chip are substantially free from the conversion layer; and

an electric connecting element at bottom surfaces of the optoelectronic semiconductor chips remote from the cover plate,

wherein the electric connecting element is arranged between two adjacent optoelectronic semiconductor chips, the electric connecting element being in direct electric contact with corresponding contact pads of the optoelectronic semiconductor chips, and

wherein at least two of the optoelectronic semiconductor chips being electrically connected by the electric connecting element.

2. The optoelectronic component according to claim 1 , further comprising a housing body covering the lateral surfaces of the optoelectronic semiconductor chip, the housing body being reflective.

3. The optoelectronic component according to claim 2 , wherein the housing body is arranged adjacent to lateral surfaces of the conversion layer.

4. The optoelectronic component according to claim 2 , wherein the housing body is in direct contact with the optoelectronic semiconductor chips, the conversion layer and the cover plate.

5. The optoelectronic component according to claim 1 , wherein the cover plate includes a glass into which particles of at least one of the following materials are introduced: a luminescence conversion material, another luminescence conversion material, a diffusor material.

6. The optoelectronic component according to claim 1 ,

wherein the conversion layer is partitioned into a number of portions,

wherein exactly one portion of the conversion layer is associated to each of the optoelectronic semiconductor chips in a one-to-one relationship,

wherein the portions are arranged laterally spaced apart from each other, and

wherein parts of a housing body are arranged between the portions.

7. The optoelectronic component according to claim 6 , wherein portions associated to different optoelectronic semiconductor chips are different from each other regarding a thickness thereof and/or material composition thereof.

8. The optoelectronic component according to claim 1 , wherein a distance between two adjacent optoelectronic semiconductor chips ranges between at least 20 μm and at most 50 μm.

9. The optoelectronic component according to claim 1 ,

wherein a sidewall of the cover plate defines a sidewall of the optoelectronic component.
