LED luminaire, particularly LED headlight, comprising an active light source (2) composed of a plurality of LEDs (21-26) that have the same color or different colors and are arranged 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 arranged in a small distance above the emission surfaces of the LEDs (21-26) and which collects and focuses the light (L1-L4) emitted by the LEDs and directed onto a surface, a mixing optical unit (4), which receives the light (K1, K2, E) that has been directed onto a surface and focussed 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 pre-determined light distribution (F1-F4) to the far field. |
