Abstract
The invention provides light generating system () comprising (i) one or more light generating devices (), (ii) a luminescence conversion arrangement (), and (iii) a diffuser arrangement (), wherein: the one or more light generating devices () are configured to generate device light (); wherein the one or more light generating devices () comprises a solid state light source (), wherein the solid state light source () comprises one or more of a laser diode and a superluminescent diode; wherein the light generating system () is configured such that, in an operational mode of the light generating system (), (a) at least part of the device light () propagates to the luminescence conversion arrangement (), and (b) at least part of the device light () propagates to the diffuser arrangement (); wherein the at least part of the device light () propagating to the diffuser arrangement () is polarized light comprising one of a first linear polarization and a second linear polarization; the luminescence conversion arrangement () comprises a luminescent material () configured to convert at least part of the device light () received by the luminescent material () into luminescent material light (); wherein the luminescent material () is configured in the reflective mode relative to device light () irradiating the luminescent material (); the diffuser arrangement () is configured to generate diffused device light () from at least part of the device light () received by the diffuser arrangement (); wherein the diffuser arrangement () comprises a polarizing beam splitter (), a quarter wave plate (), a polarization maintaining diffuser (), and a specularly reflective mirror (), wherein the mirror () comprises a metallic mirror (); the polarizing beam splitter () is (i) transmissive for one of the light having the first linear polarization and light having the second linear polarization and (ii) reflective for the other one of the light having the first polarization and the light having the second linear polarization; and the light generating system () is configured to generate system light () comprising in the operational mode of the light generating system () (i) the diffused device light () and (ii) the luminescent material light ().
