Patent ID: 8113694

Claim:
A notification device comprising: a housing configured to be installed on a wall; a reflector unit mounted to the housing and symmetrical about a vertical axis, the reflector unit comprising: a base comprising: a curved portion centered on the vertical axis; a flat portion extending from the curved portion on a first side of the vertical axis and a second side of the vertical axis; a reflective flange extending from a location near a top side of the base and along a plane perpendicular to the wall, the reflective flange having a lower surface that tapers from the vertical axis toward the top side of the base; a first specular protrusion and a second specular protrusion extending from the curved portion of the base, wherein the first specular protrusion is positioned on the first side of the vertical axis and the second specular protrusion is positioned on the second side of the vertical axis, the first specular protrusion and the second specular protrusion each comprising a surface substantially directed toward a lower edge of the base near the vertical axis; a third specular protrusion and a fourth specular protrusion extending from the base, wherein the third specular protrusion is positioned on the first side of the vertical axis and the fourth specular protrusion is positioned on the second side of the vertical axis, the third specular protrusion and the fourth specular protrusion each extending from a lower edge of the base and tapering in a direction parallel to the vertical axis; a fifth specular protrusion and a sixth specular protrusion extending from the curved portion of the base, wherein the fifth specular protrusion is positioned on the first side of the vertical axis and the sixth specular protrusion is positioned on the second side of the vertical axis, and wherein the fifth specular protrusion is proximate to the third specular protrusion on a side of the third specular protrusion nearest the vertical axis and the sixth specular protrusion is proximate to the fourth specular protrusion on a side of the fourth specular protrusion nearest the vertical axis, the fifth specular protrusion and the sixth specular protrusion each having a curved surface substantially directed toward a central point of the curved portion of the base; and a seventh specular protrusion and a eighth specular protrusion extending from the flat portion of the base, wherein the seventh specular protrusion is positioned on the first side of the vertical axis and the eighth specular protrusion is positioned on the second side of the vertical axis, and wherein the seventh specular protrusion and the eighth specular protrusion each taper toward the vertical axis; a lens coupled to the housing and positioned over the reflector unit; and a lamp positioned in the center of the curved portion of the base.
