Patent
CA 2286972
A ballast is disclosed which can operate at an effective level of output with a number of different input voltage levels. A ballast is also disclosed that uses a ceramic (148) as a heat sink for switching transistors (144, 86, 96). A ballast is further disclosed which uses a start signal (48) for a power factor circuit (40) to boost voltage after the load for the ballast has already has a current applied to it. Furthermore, a ballast is disclosed which has a transformer (100) having a permeability which varies somewhat inversely with temperature over a given temperature range.
L'invention concerne un ballast pouvant fonctionner à un niveau efficace de sortie avec plusieurs niveaux différents de tension d'entrée. L'invention concerne aussi un ballast utilisant un matériau en céramique (148) en tant que puits de chaleur pour transistors de commutation (144, 86, 96). L'invention concerne en outre un ballast qui met en oeuvre un signal de départ (48) destiné à un circuit ayant un facteur de puissance afin d'amplifier la tension après que la charge du ballast a déjà reçu un courant. L'invention porte encore sur un ballast comprenant un transformateur (100) dont la perméabilité varie de manière sensiblement inverse par rapport à la température sur une plage de températures données.
