N2 - A wavelength converting element (104), typically for a LED (101), is provided, comprising luminescent particles (105) dispersed in materix (106) comprising crosslinked polysiloxane. Crosslinked polysiloxane are termperature stable, typically up to temperatures above 300 °C, meaning that they are stable under normal operating conditions of light emitting diodes. Further, crosslinked polysiloxanes are stable towards exposure to light, meaning that they will not degrade/discolor as a consequence of high intensity light exposure. The polymeric wavelength converter can easily be shaped in different forms. This may lead to better outcoupling of the light from a LED-converter system.
