摘要
Infrared radiation fire detector, comprising a curved support surface (12) and a plurality of infrared radiation sensors (14) arranged on the support surface (12). Each sensor (14) comprises a planar array (15) of infrared radiation-sensitive elements (16), having a respective sight direction (SD) and a solid angle of view (²) defined around the sight direction (SD), which define a field of view associated to the sensor (14). The sight directions (SD) of the sensors (14) intersect with one another at a central point (C) and the sensors (14) are spaced apart from one another by a given angular distance referred to the central point (C), the solid angles of view (²) of the sensors (14) having a same narrow width so that the fields of view of the sensors are non-intersecting with one another.
