Definitions

  • the boost circuit and the rectification filter circuit form a boost rectifier filter circuit, and the boost rectifier filter The output end of the circuit is connected to a constant current output circuit.
  • the boost rectification filter circuit is composed of four rectifier diodes and two capacitors. The anode of the first rectifier diode and the cathode of the second rectifier diode are connected to the boost rectifier filter circuit.
  • the constant current output circuit is composed of a constant current driving chip, a resistor and a diode, an inductor and two series connected capacitors.
  • the first pin of the constant current driving chip is connected to the anode of the diode, and the cathode of the diode is connected to the boost at the same time.

Abstract

Cette invention concerne un convertisseur d'alimentation et une lampe à diode électroluminescente (DEL). Ledit convertisseur d'alimentation comprend un circuit de conversion (2) comprenant un redresseur et un circuit de filtrage (22) ainsi qu'un circuit de sortie de courant constant (23). La puissance de sortie maximale du circuit de conversion (2) peut atteindre de 4W à 12W, et il peut fonctionner de manière stable. Un circuit de filtrage (21) des interférences électromagnétiques (EMI) est également connecté aux bornes d'entrée du circuit de conversion (2) pour limiter l'interférence électromagnétique. De plus, une piézorésistance (VR1) est connectée en parallèle aux bornes de sortie du redresseur et au circuit de filtrage (22) pour empêcher le claquage d'un circuit intégré de génération de courant quand il n'y a pas de charge aux bornes de sortie du circuit de conversion (2). Le convertisseur d'alimentation est connecté à la lampe à DEL de sorte à assurer l'alimentation électrique de la lampe.
