Patent ID: 7642707

Claim:
A light source to emit a mixture of primary and secondary light comprising an electroluminescent device like a light emitting diode LED or a laser to emit the primary light, a light conversion element ( 3 ) to convert the primary light into the secondary light, wherein a first part of the primary light is emitted along a light path with a first conversion factor ( 11 ) for the primary light and a second part of the primary light is emitted along a light path with a second conversion factor ( 12 ) for the primary light larger than the first conversion factor, wherein the first part of the primary light is coupled into at least one first area ( 4 ) of the conversion element ( 3 ) and the second part of the primary light is coupled into at least a second area of the conversion element ( 3 ), and wherein the conversion element ( 3 ) comprises a regular pattern of equidistant first areas ( 4 ), and/or the first area ( 4 ) has a shape of a cross-like slit in light emitting direction ( 12 ).
