Abstract
A laser light source arrangement for a laser projection device includes a laser diode array. The laser diode array includes a first light group with at least one first laser diode and a second light group with at least one second laser diode. The first laser diode and the second laser diode include spectrally different emission maxima. The first laser diode includes an emission maximum in a wavelength range of 440-462 nm. The second laser diode includes an emission maximum in a wavelength range of 462-472 nm. The laser diode array is accommodated in a housing in such a way that the beam paths of the first laser diode and the second laser diode extend spatially separated within the housing.
