Abstract
In an embodiment, the optoelectronic semiconductor device comprises an optoelectronic semiconductor chip for emitting a radiation. An optical element is disposed downstream of the semiconductor chip. The semiconductor chip and the optical element are embedded in a potting body. The optical element comprises a structured, contiguous and optically effective area, which is located inside the optical element directly at an optical contrast region, preferably an evacuated or gas-filled cavity. The optically effective area completely covers a radiation exit area of the semiconductor chip.

An optoelectronic semiconductor device comprising:
- an optoelectronic semiconductor chip for emitting radiation,
- an optical element disposed optically downstream of the semiconductor chip, and
- potting body in which said semiconductor chip and said optical element are embedded,
- wherein
- the optical element comprises a structured, contiguous and optically effective area which is located inside the optical element directly at an optical contrast region, so that a refractive index jump of at least 0.4 is present between the optically effective area and the optical contrast region,
- the optically effective area completely covers a radiation exit area of the semiconductor chip, and
- the potting body directly surrounds the semiconductor chip and the optical element all around laterally in a form-fitting manner.
