Title
(EN) LED LIGHT COLLECTION AND UNIFORM TRANSMISSION SYSTEM
(FR) SYSTEME DE RECUEIL ET DE TRANSMISSION UNIFORME DE LA LUMIERE D'UNE DEL
Abstract
(EN)
Apparatus for collecting light from an LED and transmitting it in a near­uniform column includes a conical reflector about the base of the LED for collecting light emitted to the sides of the LED, and a lens specially designed to focus the collected light into a near-collimated beam. The lens has opposite, substantially elliptical surfaces to collect and collimate the rapidly diverging light from the LED and the reflector, and each lens surface includes a flat spot to prevent shadows from forming, thereby producing a more uniform beam.
(FR)
L'invention porte sur un appareil de recueil de la lumière d'une DEL et la transmettant de manière quasi-uniforme en une colonne. A cet effet un réflecteur conique entourant la base de la DEL recueille sa lumière émise latéralement, tandis qu'une lentille spéciale la focalise en un faisceau quasi-collimaté. La lentille, qui présente des surfaces opposées sensiblement elliptiques recueillant et collimatant la lumière fortement divergente de la DEL et du réflecteur, comporte une petite surface plane empêchant la formation d'ombres, et renforçant par-là l'uniformité du faisceau.
