Patent ID: 8358058

Claim:
A lighting system, comprising: a light source; and at least one luminophore placed in front of it for at least partial conversion of the light source's radiation into longer-wave radiation, wherein the light source is configured to emit primary radiation with a peak wavelength in the range of from 300 to 420 nm; and wherein a luminophore used for the conversion is a mixture of an aluminate of the BAM host lattice type and a low Ba-aluminate, the mixture having the stoichiometry M x Eu 1−x Mg 1−y+d Mn y Al 10+2f O 17+d+3f , wherein 0.2≦x≦0.48; 0≦y≦0.3; 0≦d≦0.1; 0.1≦f≦1.0; and wherein M is at least one of the group consisting of Ba, Sr and Ca.
