摘要： 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)SrO x(Ba, Ca)O (1-a-b-c-d)SiO2 aP2O5 bAl2O3 cB2O3 dGeO2: y Eu2+ and/or (2-x-y)BaO x((Sr, Ca)O (1-a-b-c-d)SiO¿2? aP2O5 bAl2O3 cB2O3 dGeO2: y Eu?2+¿. The desired color (color temperature) can be easily adjusted by using a luminophore of the aforementioned type. The light source can contain an additional luminophore selected from the group of alkaline-earth aluminates, activated with bivalent europium and/or manganese, and/or can contain an additional red-emitting luminophore selected from the group Y(V, P, Si)O¿4?:Eu or can contain alkaline-earth magnesium disilicate.
