| titleOfInvention | Circuit for feeding a lamp |
| abstract | An electric lamp for the photopolymerization of dental materials is supplied with constant electric power so that constant light output is obtained. The control circuit used to this end operates with a triac (3) connected between an a.c. voltage supply (2) and the lamp (1), said triac being controlled by signal values stored in a read-only memory of a microprocessor (4). Said stored values are respectively allocated to pairs of instantaneous values of lamp current and lamp voltage, the instantaneous values being detected in each cycle of the a.c. supply voltage and being utilized to address the read-only memory. |
