Abstract

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±0.005 and 0.5408±0.005 in the CIE color space during operation. A fourth semiconductor chip may emit electromagnetic radiation having color space coordinates of 0.5638±0.005 and 0.4113±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.
