The invention relates to a converter ( 25, 35, 45, 55, 65, 75, 85, 95, 115, 125 ) for a lighting device, in particular for a lighting device for a motor vehicle headlight, wherein the converter comprises a converter material ( 24, 34, 44, 54, 64, 74, 84, 94, 114, 124 ) for at least partly converting a primary light, which is emitted from a primary light source, into a secondary light, wherein the secondary light has a different wavelength than the primary light, wherein the converter comprises a flat diamond support structure ( 20, 30, 40, 50, 60, 70, 80, 90, 110, 120 ) made of polycrystalline diamond with a plurality of column-shaped diamond crystals ( 23, 33, 43, 53, 63, 73, 83, 93, 113, 123 ), which form a column-shaped diamond texture, wherein regions ( 22, 32, 42, 52, 62, 72, 82, 92, 112, 122 ) of the diamond support structure comprise the converter material ( 24, 34, 44, 54, 64, 74, 84, 94, 114, 124 ), and free spaces remain between said regions, the free spaces allow the primary light to pass through the diamond support structure without being converted. |
