Photo curing light system having modulated light intensity control

摘要

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.
