INTEGRATED INFRARED GAS SENSOR HAVING SPECIAL-SHAPED GAS CHAMBER AND USAGE METHOD THEREFOR

摘要：

An integrated infrared gas sensor having a special-shaped gas chamber and a usage method therefor. The integrated infrared gas sensor having a special-shaped gas chamber comprises: a circuit board (1) and an optical gas chamber (2), wherein the optical gas chamber (2) is mounted on the circuit board (1), the optical gas chamber (2) comprises a first reflective member (21) and a second reflective member (22), the longitudinal cross-section of each of the first reflective member (21) and the second reflective member (22) is in a parabolic shape, and an accommodating space (3) is formed between the first reflective member (21) and the circuit board (1); a light source assembly (4), wherein the light source assembly (4) is mounted on the circuit board (1), and the light source assembly (4) is located in the accommodating space (3); and a detection assembly (5), wherein the detection assembly (5) is mounted on the circuit board (1), and the detection assembly (5) is located in the accommodating space (3). Mutual cooperation between the first reflective member (21), the second reflective member (22), the light source assembly (4) and the detection assembly (5) enables a small-size sensor to have a large optical path and luminous flux, and have improved sensitivity and an improved response speed.
