Digital control of power supply used in regulation of halogen lamp

This paper deals with a developed digital control procedure used to regulate a halogen lamp. The digital process allowing the extraction of spectral irradiance characteristics was presented. Power consumption progress was given to determine the spectral intensity of 250W halogen lamp. To obtain these proprieties we use PIC18F family's microcontroller as a manager to operate the lamp in the appropriate conditions. The regulation of irradiance intensity was given in optimized procedure of current or voltage developed in embedded system.
