Abstract:
1. A lighting system comprising: a light source unit and a projection system for generating a predetermined light pattern in a target area, wherein the light source unit comprises at least one light source and a plurality of collimators which are arranged side by side in the form of an array comprising a number of lines, each seen in a projection plane perpendicular to the optical axis of the projection system, and each collimator comprising an entry aperture through which light emitted by the at least one light source enters the collimator and light reflecting surfaces for reflecting and directing the light entered into the collimator through an exit aperture of the collimator and into the projection system, wherein the collimators are configured such that either the exit aperture of the collimator, or at least one of front rims of the light reflecting surfaces of the collimators which enclose and mark the boundary of the exit aperture of each of the collimators are at least substantially coincident with and at least substantially follow at least a part of a curved focal plane (P) of the projection system, or are configured such that the curved focal plane (P) of the projection system intersects with or tangentially touches the exit aperture or at least one of the rims, respectively.
