Active night vision cooling system

摘要

A thermal control system ( 11 ) for a light source ( 46 ) of a vision system ( 10 ) includes a cooling assembly ( 61 ) that has a cooling device ( 62 ) and is thermally coupled to the light source ( 46 ). A thermal sensor ( 60 ) is thermally coupled to the light source ( 46 ) and generates a light source temperature signal. A control circuit ( 50 ) is coupled to the cooling assembly ( 61 ) and to the thermal sensor ( 60 ) and operates the cooling device ( 62 ) when the light source temperature signal is above a minimum temperature limit.
