Title: INTEGRATED SMOKE DETECTION DEVICE
Abstract:
The integrated smoke detection device comprises a carrier (1), a light source (2) arranged on or above the carrier, a light receiver (3) arranged on or above the carrier at a distance from the light source, and a polarizing member (7) arranged on or above the carrier, the light source emitting radiation (a, b) into the polarizing member. The polarizing member is configured to have a boundary surface (11) that linearly polarizes a reflected portion (d) of the radiation emitted by the light source, and an exit surface (12) that allows the reflected portion (d) to exit the polarizing member.
