  • Publication number: 20060267031
    Abstract: The invention relates to a light source comprising a light-emitting element, which emits light in a first spectral region, and comprising a luminophore, which comes from the group of alkaline-earth orthosilicates and which absorbs a portion of the light emitted by the light source and emits light in another spectral region. According to the invention, the luminophore is an alkaline-earth orthosilicate, which is activated with bivalent europium and whose composition consists of: (2-x-y)SrOx(Ba, Ca)O (1-a-b-c-d)SiO2aP2O5bAl2O3cB2O3dGeO2: y Eu2+ and/or (2-x-y)BaOx((Sr, Ca)O (1-a-b-c-d)SiO2aP2O5bAl2O3cB2O3dGeO2: y Eu2+. The desired color (color temperature) can be easily adjusted by using a luminophore of the aforementioned type.

  • Patent number: 7138660
    Abstract: The light emitting device has a light emitting diode which is made of a nitride semiconductor and a phosphor which absorbs a part of lights emitted from the light emitting diode and emits different lights with wavelengths other than those of the absorbed lights. The phosphor is made of alkaline earth metal silicate fluorescent material activated with europium.
