Abstract: A light source. The light source includes as components which superimpose one another in this sequence: a first light-emitting semiconductor component; a first carrier element comprising a first carrier surface which faces the first light-emitting semiconductor component and a first cooling surface deliminating at least in part a first fluid path; and a distributor element comprising a first cavity and a further cavity. The first cavity and the further cavity are fluidically connected to one another by the first fluid path. Also disclosed are a printing machine; methods, in particular for producing a printed product, for irradiating a material to be irradiated, and for producing a light source; corresponding method products; an assembly having the light source; and uses of the light source.

Abstract: A luminaire for irradiating a target such as a printed product with printed-on lacquer or the like. The luminaire has a plurality of semiconductor light sources, wherein at least two first semiconductor light sources form a first light source line oriented in a lateral direction and wherein at least two further semiconductor light sources form a second light source line oriented in the lateral direction. The luminaire also has a plurality of separate lenses for collimating and/or collecting light from the semiconductor light sources, wherein each of the light source lines is assigned to one of the lenses.

Abstract: An irradiation system is provided. The irradiation system includes a plurality of LED arrays, each of the LED arrays including a plurality of LED light producing elements. The irradiation system also includes a target area, the target area being adapted to receive light energy from each of the plurality of LED arrays. The plurality of LED arrays are positioned with respect to one another such that they surround the target area of the irradiation system.
