Title (EN) LIGHTING DEVICES INCLUDING A LENS AND A COMPOSITE ENCAPSULANT, AND METHODS OF MAKING THE SAME
(FR) DISPOSITIFS D'ÉCLAIRAGE COMPRENANT UNE LENTILLE ET UN AGENT D'ENCAPSULATION COMPOSITE, ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) There is herein described a lighting device including a composite encapsulant and an optical component. The lighting devices include a first interface between the composite encapsulant and a light emitting surface of a light source, and a second interface between the composite encapsulant and the optical component. In various embodiments, the composite encapsulant is configured to increase a critical angle at the first interface, so as to limit total internal reflection at the first interface. Moreover, the properties and/or other features of the composite encapsulant may be controlled to also limit total internal reflection at the second interface. Methods of making such lighting devices are also disclosed.
(FR) L'invention concerne un dispositif d'éclairage comprenant un agent d'encapsulation composite et un composant optique. Les dispositifs d'éclairage comprennent une première interface entre l'agent d'encapsulation composite et une surface électroluminescente d'une source de lumière, et une seconde interface entre l'agent d'encapsulation composite et le composant optique. Selon divers modes de réalisation, l'agent d'encapsulation composite est conçu pour augmenter un angle critique au niveau de la première interface, de manière à limiter la réflexion interne totale au niveau de la première interface. De plus, les propriétés et/ou d'autres caractéristiques de l'agent d'encapsulation composite peuvent être contrôlées pour limiter également la réflexion interne totale au niveau de la seconde interface. L'invention concerne également des procédés de fabrication de tels dispositifs d'éclairage.
