Abstract
Abstract The semiconductor heat-fault detector of this invention comprises a barrel, an infrared generator, and lens means. The infrared generator is disposed at the terminal end of the body portion at its end opposite the lens portion with the infrared generator directed into the barrel. The infrared generator is powered from a suitable source, and has a preselected intensity. The lens means is disposed in the lens portion of the barrel, and is operable to condense and focus energy emitted from the generator.
