Abstract: A method for generating a light emission pattern by illuminating at least one phosphor surface by at least one primary light beam is provided. The method includes: directing the primary light beam only onto a partial surface of the entire illuminatable phosphor surface; and illuminating at least one partial region of said partial surface more intensely than in the case of uniform illumination of the illuminatable phosphor surface.

Abstract: A method for operating a lighting device comprising n>1 light generating units configured to generate a respective primary light beam and comprising a phosphor surface spaced apart from the light generating units is provided. The method may include illuminating an i-th partial surface of the phosphor surface by i light generating units if a desired positive brightness value on this illuminated partial surface falls below or reaches a next higher i-th brightness threshold value from a group of n−1 positive, progressively increasing brightness threshold values; otherwise illuminating by n light generating units; wherein i and n are whole natural numbers and i=[1, . . . , n] holds true.

Abstract: A lighting device for a headlight for generating a light emission pattern in a far field is provided. The lighting device includes at least two phosphor surfaces arranged rotationally movably between different positions, and at least one light source spaced apart from the phosphor surfaces and serving for emitting primary light for illuminating a portion of the phosphor surfaces. An associated predetermined light emission pattern is generatable in respectively exactly one predetermined position of the phosphor surfaces.

Abstract: A lighting device may include a laser light source arrangement; an optical unit; at least one pivotable mirror; and at least one light wavelength conversion element. The optical unit and the at least one pivotable mirror are embodied in such a way that laser light generated by the laser light source arrangement is directed via the optical unit and the at least one pivotable mirror to the light wavelength conversion element. The lighting device may further include a unit configured to compensate for a lengthening or shortening—caused by the pivoting movement of the at least one pivotable mirror—of the optical path of the laser light generated by the laser light source arrangement and directed onto the at least one light wavelength conversion element via the optical unit and the at least one pivotable mirror.
