Title (EN) MICROCONTROLLER OPTIMIZED PULSE-WIDTH MODULATION (PWM) DRIVE OF A LIGHT EMITTING DIODE (LED)
(FR) ATTAQUE PAR MODULATION D'IMPULSIONS EN DURÉE (PWM) OPTIMISÉE PAR MICROCONTRÔLEUR, D'UNE DIODE ÉLECTROLUMINESCENTE (DEL)
Abstract: front page image
(EN)The invention proposes a method for operating a controlled illumination apparatus, the illumination apparatus comprising at least one PWM controlled LED, the method comprising the following steps: - carrying out a duty cycle sweep of the PWM signal driving the at least one LED while sensing at least one parameter indicative of the power consumption of the at least one LED in order to compute a curve reflecting the duty-cycle dependency of the power efficiency of the at least one LED.
(FR)L'invention concerne un procédé de fonctionnement d'un dispositif d'éclairage commandé, ce dispositif comprenant au moins une DEL commandée par modulation d'impulsions en durée. Le procédé comporte les étapes consistant à: mettre en œuvre un balayage du cycle d'utilisation du signal PWM pilotant la ou des DEL pendant la détection d'au moins un paramètre indiquant la consommation d'énergie de la ou des DEL, afin de calculer une courbe reflétant la relation de dépendance entre le cycle d'utilisation et la consommation d'énergie de la ou des DEL.
