Abstract
A lighting device may include a light generating unit configured to generate at least two light beams; at least one phosphor surface which is illuminatable by the light beams; and at least one movable deflection mirror for the scanning deflection of the light beams onto the phosphor surface, 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 lighting device, comprising:
- a light generating unit configured to generate at least two light beams;
- at least one phosphor surface which is illuminatable by the light beams;
- and
- at least one movable deflection mirror for the scanning deflection of the light beams onto the phosphor surface,
- 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 a light emission pattern, the method comprising:
- illuminating at least one phosphor surface by at least two light beams such that at least one region of the phosphor surface is illuminated by at least two light beams in a manner spaced apart temporally.
