摘要： The present invention can detect smoke with high accuracy. A light emitting portion is provided with a light emitting element outputting the inspection light with high brightness, the distribution of which is adjusted. A reflection portion collects the inspection light from the light emitting element to the detection region. A diaphragm portion transmits the collected light toward the detection region, while removing light diffused to regions other than the detection region a light shielding portion shields the light diffused to the regions other than the detection region. The light emitting element is provided with a light source outputting the inspection light with high brightness and a parabolic reflective mirror whose curved surface reflects light from the light source toward the detection region, the reflected light being in a doughnut shape in which the center is relatively dark and the periphery is bright.

摘要： A photoelectric smoke detector may detect presence of smoke by utilizing a light emitting element and a light receiving element whose optical axes intersect with each other. The photoelectric smoke detector may include a casing for storing the light emitting element and the light receiving element. Inlet and outlet ports may be respectively provided in one and the other sides of the casing, the inlet and outlet ports bringing air flow into the casing. Rectifying light blocking means may be provided contiguously with each of the inlet and outlet ports, the rectifying light blocking means preventing entry of disturbance light into an interior space and forming a flow line of smoke extending from one or the other inlet and outlet port to the other or the one inlet and outlet port such that the flow line passes through a detection area by the light emitting element and the light receiving element.
