First Claim
1. A notification device comprising:
- a housing configured to be installed on a ceiling;
a reflector unit mounted to the housing, the reflector unit comprising;
a base having a reflective curved surface, wherein a curvature of the curved surface is symmetrical about a central axis extending through the base;
a plurality of reflective fins, wherein each reflective fin comprises;
a first fin portion extending from the curved surface of the base; and
a second fin portion extending from the curved surface of the base and the first fin portion, the second fin portion having an inner surface and an outer surface, wherein the inner surface is exposed to the central axis; and
a surface portion extending from the curved surface of the base and positioned between the first fin portion and an edge of the base,wherein the surface portion is angled toward an inner surface of the second fin portion;
a lens coupled to the housing and positioned over the reflector unit; and
a lamp positioned in the center of the reflector unit along the central axis.

Abstract
A ceiling notification device has a housing; a reflector unit mounted to the housing; a lens positioned over the reflector unit; and a lamp in the center of the reflector unit along the central axis. The reflector unit has a base, a plurality of reflective fins, and a surface portion. The base has a curved surface that is symmetrical about a central axis. The plurality of reflective fins each has a first fin portion extending from the base and a second fin portion extending from the base and the first fin portion, the second fin portion having an inner surface and an outer surface, wherein the inner surface is exposed to the central axis. The surface portion extends from the base and positioned between the first fin portion and an edge of the base and is angled toward an inner surface of the second fin portion.
