发明名称 |
Radiation emitting device with variable spectral properties, superimposes beams from luminescent dyes with different absorption spectra excited by LEDs with different emission spectra |
摘要 |
The device includes at least two LEDs with different emission spectra and separately controlled. At least one common conversion element contains at least two luminescent dyes of different absorption and emission spectra. Each dye is predominantly excited by one respective LED. The emitted light from the device comprises additively superimposed beams. |
