A laser light source of a projector configured to project image frames in sequence is described, comprising N light emitting sub-units emitting light of the same or similar color, wherein N is greater than or equal to 2, and wherein each light emitting sub-unit can be driven independently of each other. When the light source has to be dimmed, the at least one light emitting subunit is switched off or interrupted or steered during a time interval of at least 1/N of the time that the image frame is projected.)
