Abstract
The invention provides a light generating system () comprising one or more light generating devices (), a first luminescent material element (), a second luminescent material element (), first polarization optics (), second polarization optics (), and third optics (), wherein: (a) the one or more light generating devices () are configured to generate device light (); (b) the first luminescent material element () comprises a first luminescent material () configured in a light receiving relationship with one or more of the one or more light generating devices () and configured to convert at least part of the received device light () into first luminescent material light (); (c) the second luminescent material element () comprises a second luminescent material () configured in a light receiving relationship with one or more of the one or more light generating devices () and configured to convert at least part of the received device light () into second luminescent material light (); (d) the first polarization optics () are configured downstream of the first luminescent material () and upstream of the third optics (); wherein the first polarization optics () are configured to provide first luminescent material light () having a first polarization; (e) the second polarization optics () are configured downstream of the second luminescent material () and upstream of the third optics (); wherein the second polarization optics () are configured to provide second luminescent material light () having a second polarization different from the first polarization; and (f) the third optics () are configured to combine in an operational mode of the light generating system () the polarized first luminescent material light () and the polarized second luminescent material light (); and wherein the third optics () comprises a reflective polarizer.
