Title
(EN) SOLID-STATE LAMP WITH ANGULAR DISTRIBUTION OPTIC
(FR) LAMPE À SEMI-CONDUCTEURS À OPTIQUE DE DISTRIBUTION ANGULAIRE
Abstract
(EN)
A solid-state lamp (200) with an angular distribution optic (220) is disclosed. Embodiments of the present invention can provide for improved luminous intensity distribution in the vertical plane for a vertically oriented solid-state lamp. A lamp according to some example embodiments of the invention includes at least one LED (214), an optically transmissive enclosure (202) for the LED or LEDs, and a base. The lamp also includes a distribution optic (220) conformably disposed in or on the base to conduct light for angularly distributed emission from the base of the lamp. In some embodiments, the lamp is dimensioned as a replacement for a candelabra type incandescent bulb. The distribution optic can be composed of any optical medium, and in some embodiments, may be from about 1 mm to about 5 mm thick. In some embodiments, the distribution optic is made of thermally conductive plastic.

L'invention concerne une lampe à semi-conducteurs (200) à optique de distribution angulaire (220). Des modes de réalisation de la présente invention peuvent fournir une distribution d'intensité lumineuse améliorée dans le plan vertical pour une lampe à semi-conducteurs orientée verticalement. Une lampe selon certains modes de réalisation illustratifs de l'invention comprend au moins une DEL (214), une enveloppe à transmission optique (202) pour la ou les DEL et une base. La lampe comprend également une optique de distribution (220) disposée de manière conforme dans ou sur la base pour conduire la lumière pour une émission répartie de manière angulaire depuis la base de la lampe. Dans certains modes de réalisation, la lampe est dimensionnée de manière à remplacer une ampoule à incandescence du type candélabre. L'optique de distribution peut être composée d'un quelconque support optique et, dans certains modes de réalisation, peut être d'environ 1 mm à environ 5 mm d'épaisseur. Dans certains modes de réalisation, l'optique de distribution est composée de matière plastique conductrice de la chaleur.
