Title (EN) SINGLE-ENDED PRIMARY INDUCTANCE CONVERTER (SEPIC) BASED POWER SUPPLY FOR DRIVING MULTIPLE STRINGS OF LIGHT EMITTING DIODES (LEDS) IN ROADWAY LIGHTING FIXTURES
(FR) ALIMENTATION DE TYPE À CONVERTISSEUR À INDUCTANCE PRIMAIRE ASYMÉTRIQUE (SEPIC) PERMETTANT L'ATTAQUE D'UNE PLURALITÉ DE CHAÎNES DE DIODES ÉLECTROLUMINESCENTES (DEL) DANS DES APPAREILS D'ÉCLAIRAGE ROUTIER
Abstract: front page image
(EN)A lighting fixture and power supply are provided that allows a power factor correction (PFC) single ended primary inductance controller (SEPIC) that provides a controlled voltage output to provide a constant current to an LED load. The power supply provides an efficient and stable power supply for LEDs. Multiple power supplies can be provided on the same printed circuit board to control multiple LED channels.
(FR)Appareil d'éclairage et alimentation permettant à un convertisseur à inductance primaire asymétrique (SEPIC) de correction du facteur de puissance (PFC) produisant une tension de sortie régulée d'appliquer un courant constant à une charge de DEL. L'alimentation assure une alimentation stable et efficace des DEL. Une pluralité d'alimentations peuvent être montées sur la même carte à circuit imprimé pour commander une pluralité de canaux de DEL.
