Title (EN) VERTICAL CAVITY SURFACE EMITTING LASER ARRAYS FOR ILLUMINATION
(FR) RESEAUX DE LASERS A CAVITE VERTICALE ET A EMISSION PAR LA SURFACE POUR L'ECLAIRAGE
Abstract:
(EN) Arrays of vertical cavity surface emitting lasers ('VCSEL's) (21-26) used for illumination in both infrared and visible light wavelengths are described. By using several different arrays (21-26), each array (21-26) generating light of a different wavelength, a replacement for conventional lighting sources can be obtained. The present invention offers lower power consumption and longer operating lifetime than known lighting technologies.
(FR) L'invention se rapporte à des réseaux de lasers à cavité verticale et à émission par la surface ('VCSEL') (21-26) utilisés pour l'éclairage dans des longueurs d'ondes de lumières ultraviolettes et visibles. En ayant recours à plusieurs réseaux différents (21-26), chacun de ces réseaux (21-26) générant une lumière de longueur d'onde différente, il est possible de remplacer les sources d'éclairage traditionnelles. En comparaison avec les technologies d'éclairage connues, l'invention permet de réduire la consommation de courant et de prolonger la durée de vie des sources d'éclairage.
