Abstract
A lighting device () for illuminating a surface (). The lighting device comprises at least one first light source () configured to emit a first light beam () in a first direction and at least one second light source () configured to emit a second light beam () in a second direction that is not parallel to the first direction. The first light beam () has a first spectral power distribution, the second light beam () has a second spectral power distribution and the second spectral power distribution is different from the first spectral power distribution. The lighting device further comprises at least one light-delimiting element () adjustable relative to at least one of the at least one first light source and the at least one second light source. The at least one light-delimiting element is further configured to delimit the first light beam and the second light beam thereby modify an area of overlap on the surface () of the first light beam () and the second light beam () by forming a boundary of the light () separating the first light beam and the second light beam, such that the first light source is configured to illuminate at least a first region () of the surface, and the second light source is configured to illuminate at least a second region () of the surface adjoining the at least one first region of the surface.
