Abstract

La présente invention se rapporte à une lampe qui comporte une enceinte optiquement transmissive et une base qui définit un axe longitudinal de la lampe qui s'étend depuis la base jusqu'à l'extrémité libre de l'enceinte. Un ensemble diode DEL est positionné dans l'enceinte optiquement transmissive. L'ensemble diode DEL comprend des diodes électroluminescentes (DEL) utilisées pour émettre une lumière lorsqu'elles sont alimentées par un passage électrique à partir de la base. L'ensemble diode DEL est agencé de telle sorte que les multiples diodes électroluminescentes (DEL) soient orientées de façon perpendiculaire à l'axe longitudinal de la lampe. Le profil d'émission des diodes électroluminescentes (DEL) est une largeur à mi-hauteur (FWHM pour Full Width at Half Maximum) d'au moins 120 degrés.
