Laser smd package with phosphor and light incoupler

Abstract

The invention provides a light generating system () comprising a lighting unit (), a luminescent element (), an optical element (), and a reflective element (), wherein: (a) the lighting unit () is configured to generate a beam () of unit light (); (b) the luminescent element () comprises a luminescent material () configured to convert at least part of the unit light () into luminescent material light (); wherein the luminescent element () comprises a first luminescent element face () and a second luminescent element face (), wherein at least part of the luminescent material () is configured between the first luminescent element face () and the second luminescent element face (); (c) the optical element () comprises an external surface (), wherein the optical element () is configured between the luminescent element () andthe reflective element (), wherein a first part () of the external surface () is directed to the second luminescent face (), wherein a second part () of the external surface () is directed to the reflective element (), and wherein a third part () of the externa surface () is configured in a light receiving relationship with the lighting unit (); wherein a first area Aof the first part () is smaller than a second area Aof the second part (), wherein the optical element () is transmissive for the unit light (); (d) the reflective element () is configured to reflect unit light (); and (e) the lighting unit () is configured such that in an operational mode the lighting unit () is configured to irradiate the first element face () via transmission through the optical element () and reflection at the reflective element ().
