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.
An electrical system located in a portable battery operated light generating device comprising, a light lamp means operative to generate a light energy output, a battery means coupled to said light lamp means and operative to provide electrical voltage for activating said light lamp means, microprocessor means coupled to said light lamp means and to said battery means, and in response to the energy condition in said battery means to generate a series of electrical pulse signals, transistor means connected to said microprocessor means and to said battery ...
