▎ 摘　　要

NOVELTY - The sensor has a heating module set provided with a visible light module and an illumination module. Multiple graphene forms an open cavity heat insulation layer. An infrared light module set in the open cavity. A graphene heat insulating layer is separated with heat conduction between the infrared light module and the heating module set. An open type cavity body far away from a side of the heating module is provided with an opening. A Graphene heat insulation layer is provided with a pulling sheet. The Graphene heat insulation layer is formed with an adhesive layer, where the adhesive layer is a heat-conducting glue layer. USE - Infrared-light sensor. ADVANTAGE - The sensor effectively realizes thermal isolation between heating mold set with infrared light module, improves measuring precision of the infrared light module, reduces temperature drift, weight and volume of the infrared sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an infrared-light sensor.
