  • Radiation-emitting device
    Patent number: 12113156
    Abstract: A radiation-emitting device may include a radiation-emitting semiconductor chip configured to emit electromagnetic radiation of a first wavelength range from a radiation exit surface, a first phosphor configured to convert electromagnetic radiation of the first wavelength range into electromagnetic radiation of a second wavelength range. The second wavelength range may be or include infrared light. The device may further include an up-converting phosphor configured to convert infrared light of the second wavelength range into visible light.
    Type: Grant
