Abstract
This electrical system is for use in a portable hand-held battery operated light curing device. The system includes a microprocessor which is activated by the battery to provide a series of square wave signals to the light curing lamp such that the light output of the light curing lamp is constant over a selected period of time. The system also provides a fast charging circuit for recharging the battery over a relatively short period of time.
