Abstract (en)

[origin: WO2010060775A1] The invention relates to a method and to a device for adjusting the color point of a lighting unit, wherein the lighting unit comprises semiconductor-based lasers for producing an RGB signal. At least one component of the RGB signal, particularly a light ray originating from a semiconductor-based laser, is fed through a filter to a sensor, and at least one of the semiconductor-based lasers is controlled based on the signal detected by the sensor.
