In one embodiment, the optoelectronic semiconductor component comprises at least one semiconductor chip for generating a primary radiation, and also an optical body disposed optically downstream of the semiconductor chip. A reflector surrounds the optical body laterally all around in a positively locking manner and is configured for reflecting the primary radiation and visible light. The optical body has a base surface facing the semiconductor chip and an exit surface facing away from the semiconductor chip. The optical body tapers in a direction away from the semiconductor chip. A quotient of the base surface and a height of the optical body is between 1 mm and 30 mm inclusive.

An optoelectronic component may include four semiconductor chips arranged on a substrate. A first semiconductor chip may be configured to emit electromagnetic radiation with a dominant wavelength ranging from about 610 to about 650 nm during operation. A second semiconductor chip may be configured to emit electromagnetic radiation with a dominant wavelength ranging from about 450 to about 475 nm during operation. A third semiconductor chip may be configured to emit electromagnetic radiation with color space coordinates of 0.3231&#xb1;0.005 and 0.5408&#xb1;0.005 in the CIE color space during operation. A fourth semiconductor chip may emit electromagnetic radiation having color space coordinates of 0.5638&#xb1;0.005 and 0.4113&#xb1;0.005 in the CIE color space during operation. The third and fourth semiconductor chips may have a conversion layer configured to convert a wavelength of the electromagnetic radiation emitted by the active region.
