Title (EN) LED LAMP WITH DIFFUSER HAVING SPHEROID GEOMETRY
(FR) LAMPE À DIODE ÉLECTROLUMINESCENTE DOTÉE D'UN DIFFUSEUR AYANT UNE GÉOMÉTRIE SPHÉROÏDALE
Abstract:
(EN) Embodiments of a lamp are described that use light emitting diodes (LEDs) to generate an intensity distribution that is consistent with incandescent lamps. In one embodiment, the lamp 100 comprises a diffuser 108 having a spheroid geometry with a light reflective upper portion 110 and a light transmissive lower portion 112. The lamp 100 also includes a thermal management system with a plurality of optically active heat dissipating elements 118 disposed annularly about the diffuser 108. In one example, the heat dissipating elements 118 are spaced apart from the diffuser 108 to promote convective heat dissipation.
(FR) Des modes de réalisation de la présente invention ont trait à une lampe qui utilise des diodes électroluminescentes (DEL) de manière à générer une répartition de l'intensité qui est en accord avec les lampes à incandescence. Selon un mode de réalisation, la lampe (100) comprend un diffuseur (108) qui est doté d'une géométrie sphéroïdale présentant une partie supérieure réfléchissante (110) et une partie inférieure de transmission lumineuse (112). La lampe (100) inclut aussi un système de gestion thermique qui est doté d'une pluralité d'éléments de dissipation de chaleur optiquement actifs (118) qui sont entourent le diffuseur. Selon un exemple, les éléments de dissipation de chaleur (118) sont espacés du diffuseur (108) de manière à favoriser la dissipation de chaleur par convection.
