1. A lighting system configured to generate lighting system light, wherein the lighting system light comprises one or more of (i) a first lighting system light component having a first component optical power Wopt,comp1, and (ii) a second lighting system light component having a second component optical power Wopt,comp2, wherein the lighting system comprises:
a first light source comprising a first pump light source configured to generate first pump light source light and a luminescent material configured to convert at least part of the first pump light source light into luminescent material light, wherein the first light source in combination with first optics is configured to provide the first lighting system light component, wherein the first lighting system light component comprises at least part of the luminescent material light, wherein the first lighting system light component has a first spectral power distribution with spectral intensity at a first wavelength λ1;
a second light source comprising a laser light source configured to generate laser light source light, wherein the second light source in combination with second optics is configured to provide the second lighting system light component, wherein the second lighting system light component comprises at least part of the laser light source light, wherein the second lighting system light component has a second spectral power distribution, different from the first spectral power distribution, with spectral intensity at a second wavelength X2, wherein the second wavelength λ2 is selected from the range of λ1−30 nm≤λ2≤λ1+30 nm;
a control system configured to control in at least one control mode the second component optical power Wopt,comp2 of the second lighting system light component in dependence of the first component optical power Wopt,comp1 of the first lighting system light component, wherein the control system is further configured to control in a first control mode the second component optical power Wopt,comp2 of the second lighting system light component in dependence of the first component optical power Wopt,comp1 of the first lighting system light component only above a predetermined threshold value of the first component optical power Wopt,comp1 of the first lighting system light component and the control system being configured to keep the color point of the combination of the first lighting system light component and the second lighting system light component within a predefined range of +/−0.05 of a predefined color point.
