LED luminaire, particularly LED headlight, comprising an active light source (2) composed of a plurality of LEDs (21 to 26) that have the same color or different colors and are disposed on a flat or curved surface (20, 200) or circuit board, and an optical system comprising - a collimation optics unit (3), the individual lenses of which are disposed a small distance above the emission surfaces of the LEDs (21 to 26) and which collects and focuses the light (L1 to L4) emitted by the LEDs and directs it onto a surface, - a mixing optical unit (4), which receives the light (K1, K2, E) that has been directed onto a surface and focused and mixes it in terms of the color and/or brightness, - and a field optics unit (5), which receives the light (M1, M2 or N1, N2) emitted by the mixing optics unit (4) and emits it with predetermined light distribution(F1-F4) to the far field. |
