Title (EN) LIGHT TUNNELS AND METHODS FOR MAKING SAME
(FR) TUNNELS DE LUMIÈRE ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) Light tunnels, methods for forming a light tunnel, and apparatuses including light tunnels are disclosed herein. A light tunnel includes a plurality of reflectors cooperatively engaging with one another by a series of notches therein. The inner edges of the reflectors are chamfered to improve ease of assembly and decrease chipping of the edges during assembly. An adhesive can be applied at junctions between the reflectors on their outer surfaces. This construction eliminates or retards light leakage and adhesive leakage.
(FR) L'invention concerne des tunnels de lumière, des procédés de formation d'un tunnel de lumière, et des appareils comprenant des tunnels de lumière. Un tunnel de lumière comprend une pluralité de réflecteurs venant en prise de manière coopérative les uns avec les autres par l'intermédiaire d'une série d'encoches à l'intérieur de ceux-ci. Les bords internes des réflecteurs sont chanfreinés pour améliorer la facilité d'assemblage et diminuer l'écaillage des bords pendant l'assemblage. Un adhésif peut être appliqué aux jonctions entre les réflecteurs sur leurs surfaces externes. Cette construction élimine ou retarde une fuite de lumière et une fuite d'adhésif.
