Abstract
(EN)
A plurality of light emitting diodes are selected so that the intensity of the forward direction current of the peak light emission efficiency is within a predetermined irregularity range and arranged in parallel to one another. An electric device power supply circuit from an AC power source reduces and rectifies voltage Vf to the vicinity where the light emitting efficiency is at its peak and supplies current to a plurality of light emitting diodes so as to emit light.

Selon le mode de réalisation décrit dans cette invention plusieurs diodes électroluminescentes sont sélectionnées de sorte que l'intensité d'un courant au moment du pic d'efficacité de l'émission lumineuse est comprise dans une gamme d'irrégularités prédéterminée et elles sont placées parallèlement les unes aux autres. Un circuit d'alimentation pour un dispositif électrique à partir d'une source de courant alternatif réduit et rectifie la tension Vf à proximité de l'emplacement où l'efficacité de l'émission lumineuse est à son maximum et il fournit du courant à plusieurs diodes électroluminescentes de manière à émettre de la lumière.
