Beschreibung
Zusammenfassung:	The present invention relates to a light emitting device comprising at least one light emitting diode which emits light in a predetermined wavelength region, copper-alkaline earth metal based inorganic mixed crystals activated by rare earths, which include copper-alkaline earth silicate phosphors which are disposed around the light emitting diode and absorb a portion of the light emitted from the light emitting diode and to emit light different in wavelength from the absorbed light.
