Abstract
A light emitting device () comprising a light source () having a light exit surface, a wavelength converter () configured to convert light from a first wavelength to a second wavelength, said wavelength converter having a light exit surface () and a light entrance surface, a heat sink () and an optical coupling element (), arranged in thermal connection with said heat sink () and said wavelength converter (), wherein said optical coupling element () is selected to have a refractive index lower than a refractive index of said wavelength converter (). The optical coupling element () will allow for an efficient heat transfer from the wavelength converter () to the heat sink () while avoiding loss of light from unwanted surfaces.
