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. The converter has 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, which has a different wavelength than the primary light. The converter has 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. Regions (22, 32, 42, 52, 62, 72, 82, 92, 112, 122) of the diamond support structure have the converter material (24, 34, 44, 54, 64, 74, 84, 94, 114, 124), and free spaces remain between said regions, wherein the free spaces allow the primary light to pass through the diamond support structure without being converted. |
