Abstract

An optoelectronic component may include a radiation-emitting semiconductor chip configured to emit electromagnetic radiation and a phosphor mixture. The excitation spectrum may have a peak wavelength ranging from 435 nm to 460 nm. The phosphor mixture may have three phosphors configured to emit electromagnetic radiation in different spectral ranges.
