Abstract:
A photocuring light assembly having calibration circuitry which comprises:a curing lamp; an optical light guide for providing light energy from said curing lamp; a control unit generating digital control voltage converted to analogue control voltage for providing constant current to said curing lamp; means for inputting irradiation data for curing a photosensitive composition; means for displaying said irradiation data; means for controlling light energy output to said control unit, said means for controlling light energy output including means for measuring light energy output from said optical light guide, said means for controlling light energy output programmed to incrementally increase light energy output to said curing lamp to a maximum light output while concomitantly recording and storing light energy levels, said means for controlling light energy output programmed to incrementally decrease light energy output from said maximum light output while concomitantly recording and storing light energy levels, whereby recorded and stored levels constitute light energy levels for subsequent use of said photocuring light assembly for photocuring a photosensitive composition.
