Title (EN) PROJECTION APPARATUS COMPRISING A LED CONTROL SYSTEM WITH FEEDBACK, AND DRIVING METHOD THEREFOR
(FR) APPAREIL DE PROJECTION COMPRENANT UN SYSTEME DE COMMANDE DE DIODES ELECTROLUMINESCENTES A RETROACTION ET PROCEDE D'ACTIVATION ASSOCIE
Abstract: front page image
(EN)A method of controlling power provided to one or more light emitting diodes in a projection system comprises measuring light output from the one or more light emitting diodes. Based at least upon the measured light output, the power to at least one of the light emitting diodes is modified.
(FR)L'invention concerne un procédé permettant de régler l'énergie fournie à une ou plusieurs diodes électroluminescentes dans un système de projection. Ce procédé consiste à mesurer la lumière émise par la ou les diodes électroluminescentes. Sur la base d'au moins la lumière émise, l'énergie fournie à au moins l'une des diodes électroluminescentes est modifiée.
