Smoke chamber for multiwave multiangle smoke detector
An optical chamber assembly of a detection device includes a light ring for supporting at least one light device, an optical cover defining an interior chamber of the optical chamber assembly, and an intermediate component disposed between the light ring and the optical cover. The intermediate component optically couples the at least one light device with the interior chamber. The light ring is formed from a first material, the intermediate component is formed from a second material, and the optical cover is formed from a third material, the first material, the second material, and the third material being different.
1. An optical chamber assembly of a detection device comprising:
a light ring for supporting at least one light device;
an optical cover defining an interior chamber of the optical chamber assembly; and
an intermediate component disposed between the light ring and the optical cover, wherein the intermediate component optically couples the at least one light device with the interior chamber.
2. The optical chamber assembly of claim 1 , wherein the light ring is formed from a first material, the intermediate component is formed from a second material, and the optical cover is formed from a third material, the first material, the second material, and the third material being different.
3. The optical chamber assembly of claim 1 , wherein the light ring is formed from an electrically insulating, high flame rated material.
4. The optical chamber assembly of claim 3 , wherein light absorbing properties of the intermediate component are greater than light absorbing properties of the light ring.
5. The optical chamber assembly of claim 1 , wherein the intermediate component is formed from a highly electrically conductive material.
6. The optical chamber assembly of claim 1 , wherein the optical cover is formed from a highly electrically conductive, high flame rated material.
7. The optical chamber assembly of claim 6 , wherein light absorbing properties of the optical cover are greater than light absorbing properties of the light ring.
8. The optical chamber assembly of claim 1 , wherein the optical cover includes a plurality of openings through which air is provided to the interior chamber.
9. The optical chamber assembly of claim 1 , wherein the at least one light device includes a light source and a light receiver.
10. The optical chamber assembly of claim 1 , wherein the optical chamber assembly is mounted to a printed circuit board and the intermediate component removably couples the light directly to the printed circuit board.
11. The optical chamber assembly of claim 10 , wherein the optical cover is connected to one of a ground, common or zero volt of the printed circuit board.
12. The optical chamber assembly of claim 1 , further comprising a screen connected to the optical cover to prevent debris from entering the interior chamber.
