Abstract
Devices, systems, and methods for providing an optical chamber base for smoke detection with integrated reflective surfaces for optical particle detection are described herein. One unitary reflective component insert includes a unitary reflective component insert body having a non-reflective portion and a reflective portion and wherein the reflective portion forms two emitter mirrors and a receiver mirror, wherein the emitter mirrors are shaped to direct light emitted from emitters positioned below the emitter mirrors toward a scattering zone of the optical chamber.
Claims19
A unitary reflective component insert, comprising:
- a first end including two ellipsoidal emitter mirrors shaped to direct light emitted from emitters positioned below the emitter mirrors toward a scattering zone of an optical chamber;
- a second end including a receiver mirror within a receiver cavity;
- side walls extending between the first end and the second end;
- and
- a barrier positioned at an entrance to the receiver cavity, extending across the insert, and terminating at each of the side walls.
An optical chamber base, comprising:
- a chamber base body having a cavity formed therein;
- and
- a unitary reflective component insert positioned in the cavity, wherein the unitary reflective component insert includes:
- first end including two ellipsoidal emitter mirrors shaped to direct light emitted from emitters positioned below the emitter mirrors toward a scattering zone of an optical chamber;
- a second end including a receiver mirror within a receiver cavity;
- side walls extending between the first end and the second end;
- and
- a barrier positioned at an entrance to the receiver cavity, extending across the insert, and terminating at each of the side walls.
A smoke detector of a fire sensing system, comprising:
- a circuit board body, having:
- a set of front scattering emitting light sources located on one side of an optical chamber;
- a receiver of front scattering light beams from the front scattering emitting light sources and backward scattering light beams;
- and
- a set of backward scattering emitting light sources located between the set of front scattering emitting light sources and the receiver, the backward scattering light beams emitted from the backward scattering emitters;
- and
- a unitary reflective component insert including:
- a first end including two ellipsoidal emitter mirrors shaped to reflect the front scattering light beams toward a scattering zone of the optical chamber;
- a second end including a receiver mirror within a receiver cavity;
- side walls extending between the first end and the second end;
- and
- a barrier positioned at an entrance to the receiver cavity, extending across the insert, and terminating at each of the side walls.
