A lamp is provided having at least one module that includes a plurality of LEDs distributed over a module surface. The plurality of LEDs are arranged in a row of a plurality of rows in a longitudinal direction of the at least one module. Each of the plurality of rows are arranged next to each other in a transverse direction of the at least one module that is perpendicular to the longitudinal direction. The lamp includes an optical system for bundling the light emitted by the plurality of LEDs. The optical system includes at least one cylinder lens that extends in the longitudinal direction. The light of at least some of the plurality of LEDs from a first row of the plurality of rows is bundled into a line on a target surface by the at least one cylinder lens.
