Abstract
A lighting system is disclosed which includes a light source unit and a projection system for producing a desired light distribution pattern in a target area, especially for use in an automotive head lighting, studio and theater lighting, indoor spots with adjustable beam width or direction, architectural dynamic lighting, disco lighting and other. The lighting system is especially suitable for a light source unit having one or more Lambertian light sources, especially a plurality of LEDs. For generating a desired light distribution pattern in the target area, the light source unit may include a plurality of collimators that are configured especially such that the curved focal plane (P) of the projection system intersects with or tangentially touches the exit apertures of the collimators.
