Title: LIGHT FIXTURE WITH FERRORESONANT TRANSFORMER POWER SOURCE
Abstract:
A lighting device includes a ferroresonant transformer that receives an alternating current (AC) power signal and outputs an output power signal. The lighting device further includes a rectifier coupled to the ferroresonant transformer. The rectifier rectifies the output power signal from the ferroresonant transformer and generates a rectified power signal. The lighting device also includes a dc-to-dc converter coupled to the rectifier, wherein the dc-to-dc converter receives the rectified power signal and generates a regulated power signal.
