  • Photo-curing light assembly having calibratable light intensity control
    Patent number: 6485301
    Abstract: Applicant's invention relates to a photo-curing light assembly having calibration circuitry determinative of the intensity level of the light source and the generation of an analogue control voltage from a digital control voltage during use which automatically adjusts light intensity to achieve proper energy levels during programmed curing times.

  • Photo curing light system having modulated light intensity control
    Publication number: 20020014864
    Abstract: A photo-curing light system in which a modulation of the light intensity or output is controlled via an analogue control voltage to the control line output of the lamp power supply. The control signal results in the lamp current being reduced from its maximum value to a lower value on a continuous and repeated basis thereby modulating the light and reducing the heating value to surrounding material such as tooth structure during the curing process.
