A lighting device (1) may include a light generating unit (2, 3) configured to generate at least two light beams (4, 5); at least one phosphor surface (7) which is illuminatable by the light beams (4, 5); and at least one movable deflection mirror (6) for the scanning deflection of the light beams onto the phosphor surface (7), such that the light beams impinge on the at least one phosphor surface in a spaced-apart fashion, and such that at least one region of the phosphor surface is illuminatable by at least two light beams in a manner spaced apart temporally. A method for generating optical radiation patterns comprises the steps of irradiating at least one phosphor surface (7) by means of at least two light beams (4, 5), and thereby at least one area (V) of the phosphor surface (7) are intervally irradiated by means of the at least two light beams (4, 5).
