ABSTRACT:
A system for actively monitoring and controlling the effective ambient temperature in an application utilizing a fluorescent tube as the source of illumination. The system is the combination of a fluorescent tube, which may be thermally bonded to a reflector plate that is in physical contact with thermal electric cooler units and a heat sink. A temperature sensor in conjunction with drive circuitry and a power source, directs a magnitude and direction of current flow through the thermal electric cooler units thereby controlling the ambient operating temperature of the fluorescent tube.
