Abstract
A device for defrosting the finned cooling assembly of a refrigeration system having an ellipsoid transparent polymer material housing a light source. The light source is positioned substantially in correspondence with one of the focal points of the ellipsoid. A sensor for the light beam radiated by the light source and reflected by an inner surface of the ellipsoid recognize variations in the luminous intensity of the beam caused by the formation of frost along the path of the light beam. A plurality of finned cooling assemblies are activated by the signal emitted by the sensor.
