Title (EN) POLYMERIC WAVELENGTH CONVERTING ELEMENTS
(FR) ELÉMENTS POLYMÈRES DE CONVERSION DES LONGUEURS D’ONDE
Abstract: front page image
(EN)A wavelength converting element (104), typically for a LED (101), is provided, comprising luminescent particles (105) dispersed in a matrix (106) comprising crosslinked polysiloxane. Crosslinked polysiloxanes are temperature 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.
