Patent

CA 2614208

SiO2 layers are used as adhesive layers in optoelectronic components. Permanent glued connections can be established with silicone rubbers. Said materials are usually provided with insufficient adhesion on materials that are frequently used for optoelectronic components, such as LED modules, resulting in a significant reduction of the service life of the components produced. Using the inventive adhesive layers (600, 601) makes it possible to effectively overcome said limitations while the resistance of the components during operation in a humid environment or during stresses caused by changes in temperature is substantially improved.

L'invention concerne des couches de SiO2 utilisées comme couches adhésives dans des composants optoélectroniques. Des collages durables peuvent être réalisés au moyen de caoutchoucs de silicone. Habituellement, ces matériaux ne présentent qu'une adhésivité insuffisante sur des matériaux tels qu'ils sont souvent utilisés pour des composants optoélectroniques, p. ex. des modules LED, ce qui a pour conséquence de diminuer sensiblement la durée de vie des composants fabriqués. Grâce à l'utilisation des couches adhésives (600, 601), ces limitations sont efficacement évitées et la stabilité des composants est sensiblement améliorée lorsqu'ils fonctionnent en milieu humide et sont soumis à des variations de température.
