Abstract (en)

[origin: WO2011012388A1] Specified is a light-emitting diode comprising: a light-emitting diode chip (1) emitting primary radiation in the spectral range of blue light when operating; a conversion element (34) absorbing one part of the primary radiation and re-emits secondary radiation, wherein: the conversion element (34) comprises a first fluorescent substance (3) and a second fluorescent substance (4); the first fluorescent substance (3) has in an absorption wavelength range (??ab) an absorption that decreases as the wavelength increases and the second fluorescent substance (4) has in the same absorption wavelength range (??ab) an absorption that increases as the wavelength increases; the primary radiation comprises wavelengths that lie in the stated absorption wavelength range (??ab); and the light-emitting diode emits white mixed light from primary radiation and secondary radiation, which has a color temperature of at least 4000K.
