Abstract
A radiation emitting device is disclosed. In an embodiment a radiation emitting device includes a pixelated optoelectronic semiconductor chip configured to emit a first radiation having a first peak wavelength, a conversion element or color control medium configured to convert at least a portion of the first radiation into a second radiation having a second peak wavelength and a color control element including a semiconductor diode configured to absorb a portion of the first and/or second radiation, wherein devise is configured to emit radiation of a first color temperature composed mainly of the first and second radiations when a reverse voltage is applied to the semiconductor diode and to emit radiation of a second color temperature composed mainly of the first and second radiations and a third radiation with a third peak wavelength generated by the absorbed first and/or second radiation in the semiconductor diode when a forward voltage is applied to the semiconductor diode.
