Phosphor converted superluminescent diode light source

Abstract

The invention provides a light generating system (), configured to generate system light (), wherein the light generating system () comprises a light source (), a first luminescent material (), and a control system (), wherein: —the light source () is configured to generate light source light () having a tunable spectral power distribution within a first wavelength range (Λ); wherein the light source () comprises a superluminescent diode; —the first luminescent material () is configured to convert at least part of the light source light () into first luminescent material light () having one or more wavelengths in a first luminescent material light wavelength range (Λ); —the first luminescent material () is configured such that in an operational mode the system light () comprises the first luminescent material light (); —a spectral power distribution of the system light () is controllable in dependence of the spectral power distribution of the light source light (); and —the control system () is configured to control the spectral power distribution of the light source light ().
