A closed loop control circuit maintains the radiant energy output of the diodes at substantially a predetermined value. The radiant light radiant light and a sample of a gas of interest are directed to a sensing position at which a gas responsive tape is positioned. Reflected light from the tape is detected at a sensor displaced from the tape. A light collecting element can be positioned between the coupled diodes and the sensing position."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-point gas detector","description":"A gas detection apparatus includes a housing which carries a plurality of light emitting diodes which are coupled in parallel and which emit substantially the same wavelength of radiant energy.
