Abstract

A notification appliance is disclosed. The notification appliance may be a strobe notification appliance, such as an LED strobe notification appliance. The notification appliance may be wall-mounted or ceiling-mounted. Further, the notification appliance may include an optic that is configured to shape the light output from the notification appliance. For example, in a wall-mount, the optic may be mounted off-axis of a plane defined by a back plate of the notification appliance. Further, the notification appliance may be composed of a back plate, a driver board, and a front housing, with the front housing being attached to one or both of the back plate and the driver board. Moreover, the notification appliance may be used with an adapter bracket, which may be used to connect the notification appliance with one or more types of junction boxes.

First claim

The invention claimed is:

1. A notification appliance comprising:
a connector configured for connection to a junction box;
a driver board;
one or more energy sources;
a front housing connected to one or both of a back plate and the driver board;
one or more strobe LEDs; and
an optic configured to shape light generated by the one or more strobe LEDs and mounted proximate to an LED board,
wherein the driver board, using the one or more energy sources, is configured to drive the one or more strobe LEDs,
wherein at least one of the one or more energy sources, when the connector connects the notification appliance to the junction box, are positioned in an interior of the junction box, and
wherein the one or more energy sources comprise one or more capacitors.

2. The notification appliance of claim 1 , further comprising a light pipe positioned proximate to the LED board to channel light to or from the LED board.

3. The notification appliance of claim 1 , wherein the front housing includes a screw receptacle;
wherein the optic includes a hole; and
further comprising at least one screw configured to go through the hole of the optic and engage the screw receptacle in order for the optic to press the LED board into the front housing.

4. The notification appliance of claim 1 , wherein the notification appliance comprises a plurality of LEDs; and
wherein each of the plurality of LEDs generates a light distribution.

5. The notification appliance of claim 1 , wherein a first capacitor is mounted on a first side of the driver board and a second capacitor is mounted on a second side of the driver board, the first side being opposite the second side.

6. The notification appliance of claim 5 , wherein the first capacitor and second capacitor are connected electrically in parallel.

7. The notification appliance of claim 1 , wherein a first capacitor and a second capacitor are mounted on a same side of the driver board; and
wherein both the first capacitor and the second capacitor are positioned at least partly within the junction box when the notification appliance is connected to the junction box.

8. The notification appliance of claim 1 , wherein at least one of the one or more capacitors is positioned entirely within the junction box when the notification appliance is connected to the junction box.
