Abstract

Une source de lumière à semi-conducteur (2) comprend un substrat et une pluralité de bâtonnets électroluminescents (4) de dimensions submillimétriques, lesdits bâtonnets s'étendant longitudinalement depuis ledit substrat. Selon l'invention, au moins une paroi (5) s'étend également en saillie du substrat, entre deux desdits bâtonnets, la paroi présentant des propriétés réfléchissantes des rayons émis par au moins l'un desdits deux bâtonnets électroluminescents (4).A semiconductor light source (2) comprises a substrate and a plurality of light emitting rods (4) of submillimeter dimensions, said rods extending longitudinally from said substrate. According to the invention, at least one wall (5) also extends projecting from the substrate, between two of said rods, the wall having properties that reflect the rays emitted by at least one of said two electroluminescent rods (4).
