Claims
- 1. An apparatus for curing light sensitive, polymeric compositions with a light source, an optical light guide system, a control unit for controlling the irradiation time, an input unit for inputting of the irradiation time by the user, a display unit for displaying the irradiation time set and/or remaining, a control unit for controlling the light output delivered by the light source, a light filtering system, and a means for modulating the light intensity delivered by the light source to the polymeric composition.
- 2. The apparatus in accordance with claim 1 wherein the modulation of the light intensity is controlled by a microprocessor digital signal converted to an analogue control voltage in communication with the control line output of said light source reducing lamp current from a maximum value to a lower value repeatedly.
- 3. The apparatus in accordance with claim 2 wherein said light intensity is modulated on a constant basis or on a stepped form basis by the control unit during an irradiation procedure.
- 4. A method of curing light sensitive polymeric compositions and reducing the heating affect to surrounding material utilizing a light source, an optical light guide system, a control unit for controlling the irradiation time, an input unit for inputting the irradiation time by the user, a display unit for displaying the irradiation time set and/or remaining, a control unit for controlling the light output delivered by said light source wherein said method comprises modulating said light source during the irradiation time by means of a microprocessor generating a digital signal convertible to an analogue signal by means of a digital to analogue converter integrated circuit, said analogue signal in communication with a constant current circuit having an amplifier integrated circuit and transistor, said analogue control signal reducing lamp current from its maximum value to a lower value on a continuous and repeated basis.
